Last time we spoke about the battle of Wakde. Operation Tornado, the amphibious assault of Wakde island faced many logistical challenges, but not as much Japanese resistance. The landing at Arare was a large success, seeing the allies secure a beachhead before advancing inland. Through a combination of air, naval and ground attacks, the smaller Japanese force was pushed back. Likewise the islands of Liki and Niroemoar were taken with relative ease as well. Over in the Burma-India theater, the battle for Kohima was gradually seeing the Japanese fail to meet their objectives. Without ammunition or provision supplies flowing to them, the Japanese at Kohima had no hope of holding back the allies. Thus the Japanese were beginning to fall back and now were setting up a defense to stop the allies from entering central Burma. Meanwhile a siege was being erected against Myitkyina.

This episode is the Siege of Myitkyina

Last time we saw General Stilwell had managed to seize the Myitkyina airstrip. Now allied forces were gradually securing northern Burma, pushing further towards Mogaung. The Japanese 18th Division were absolutely battered and barely holding on around Kamaing. However when the American-Chinese forces seized Myitkyina’s airstrip, they had failed to quickly attack the main town, which the Japanese were reinforcing heavily. Now they were being attacked from both ends. This prompted General Stilwell to dispatch General Boatner with the task force to try and turn things around. Simultaneously, Stilwell had just received word of the Chindits abandonment of the Blackpool stronghold, outraged by this he ordered them to advance northwards to support the attack on Mogaung.

Three brigades, the 111th, 14th and the 3rd West Africans were to advance north to support Calvert’s 77th Brigade to take Mogaung. The Chindits were incredulous. Nonetheless, Lentaigne, pressed by Stilwell, sought to have his 3rd West Africans, the 14th and 111th Brigades squeeze the Japanese along the western flanks of the Mogaung valley, in which Mogaung occupied the lowest point of an inverted triangle, with the other two points being Kamaing on the top left and Myitkyina on the top right. With any luck, his three brigades could capture Kamaing, which occupied an enviable place on the Mogaung River. The 111th Brigade was to move north-east and operate in the Pahok-Sahmaw area, destroying dumps and blocking enemy movement. Thebattered men of the 111th Brigade struggled to cope with the march north, to the hills east of Lakhren and west of Mogaung. Conditions were appalling on the three-day march to Lakhren village. From there, the best approach to Mogaung would be identified. They were making for a waterlogged, mosquito-infested area north east of the Lake. This area was also alive with Japanese units. They were required to support 77th Brigade’s attack on Mogaung, by pushing from the west as Calvert’s command advanced from the south-east. However, 111th Brigade was spent after Blackpool and many men were forced to return to Lakhren village. There was also a new task for 14th Brigade – the capture of Taungni. With the casualties evacuated, 14th Brigade abandoned the Kyunsalai Pass and headed north towards Mogaung. The steamy swamps continued to take their toll within the ranks of the York and Lancaster columns. Dysentery was rife. Animals collapsed and were shot where they dropped. They reached Mokso on June 25. This much-used rallying point, consisting of four huts, was a sea of mud and detritus, decorated with black clouds of flies. Rations were being consumed rapidly in an area devoid of drop zones. Brigadier Brodie, 14th Brigade’s Commander, responded to the extreme circumstances. His men, despite their dangerously poor condition, were still expected to harass the Japanese along the railway and support 77th Brigade’s assault on Mogaung. He formed his columns into “Light Battle Groups”, free of heavy weapons and the wounded and sick, now lying together in the mud. Meanwhile, some Nigerian units were now struggling on the road to Lakhren along the reailway, as were the York and Lancaster sick – around 300 in all, 200 of whom were dangerously ill.

On May 25th, the same day the Chindits had quit Blackpool, Stilwell ordered the Morris Force to seize Waingmaw, across the river from Myitkyina. Unfortunately, the Japanese had entrenched themselves at the town and enjoyed the luxury of a natural moat after heavy rains flooded the fields on the approaches to the town. Morrisforce was not a proper brigade, having only two columns of troops, to which a third from the 111th Brigade had been added 1,500 troops in total. It had been conceived to harass the Japanese on jungle areas. Now, they were up against fortified positions. The result was a bloodbath. Morrisforce then began to rapidly deplete in strength. By July 14th, it was to consist of exactly three platoons, roughly 120 men.

On May 31st, Boatner then launched his first coordinated attack against Myitkyina seeing the 42nd regiment reach the Waingmaw ferry road. Built up twelve feet above the neighboring paddy fields, the road gave the Japanese a magnificent defensive position, which they exploited cleverly. The Chinese recoiled from this natural fortification but were able to beat off a Japanese counterattack. The 150th Regiment reached the riverbank and drew up in an arc about a sawmill in which the Japanese had a strongpoint. Meanwhile Colonel Hunter’s 2nd battalion reinforced with engineers advanced to Radhapur where they were heavily counterattacked by the 114th Regiment. The next day, the inexperienced 236th Engineer Battalion was sent against Namkwi. The motive behind the 236th's attack was to contain the Japanese in the Namkwi area and introduce the battalion to combat under relatively easy conditions. One company of the 236th did succeed in entering Namkwi but instead of promptly consolidating to meet the inevitable Japanese counterattack fell out for a break. The Japanese counterattacked and drove the unwary engineers right back out of the village. Both the engineers and the 2600 replacements of the Galahad Unit that had recently arrived lacked adequate experience fighting the Japanese and as such suffered badly when fighting against them. Colonel Hunter’s veteran Marauders, however, had suffered ample casualties and thus needed these green replacements in order to continue existing as a fighting force. Boatner tossed a last ditch effort on June 3rd, but his Chinese forces had suffered 320 casualties and their ammunition was running low. While he waited for supplies to build up, he used his green american troops to give them some experience, the Chinese meanwhile tunneled towards the Japanese still suffering heavy casualties. This allowed more Japanese troops to break through and reinforce Myitkyina, with a huge relief force of the 52rd Division soon on its way.

Meanwhile, Lieutenant-General Matsuyama Yuzo of the depleted 56th Division was facing a deadly offensive of his own on the Yunnan front. After a series of negotiations between Chiang Kai-Shek and the Americans, it had been agreed, General Wei Lihuang’s Y Force would cross the Salween River to attack the Tengchong and Longling areas. This would effectively allow the allies to link the Ledo Road with China, bypassing the heavy Japanese concentration along the Burma Road. Although the Americans had supplied the Y Force with artillery and ammunition, the Chinese had failed to bring the Y Force divisions up to strength, and many questioned their training. Regardless, General Wei planned to have elements of the 20th army group cross the Salween at several points before initiating a full assault against Tengchong once reinforcements had been ferried through. Further south, elements of the 11th Army Group would also cross the Salween to launch attacks on Pingda and Longling.

On the night of May 11th, the Chinese forces began to cross the Salween River against little Japanese resistance, since Matsuyama had decided not to defend the crossing sites, instead placing his main line of resistance along the ridge line some 10 miles west. The 198th Division was able to assemble in front of the Mamien Pass; the 36th division was successfully ferried through Mengka; the brand new 39th Division managed to secure the Hueijen bridge and the 76th and 88th Divisions were converging on Pingda for the attack. On May 12th, the 198th were making good progress against the Mamien Pass as the 36th had surrounded the Japanese outposts in the eastern end of the Tiantouzhai pass. However Colonel Kurashige Yasuyoshi had his 148th regiment launched two surprise night counterattacks. All that night, the Japanese quietly filtered down from a nearby ridge and assembled near the Chinese position. Attacking at dawn, they surprised the Chinese and almost wiped them out before aid came. When darkness came, the 36th were at their bivouac. That night, the Japanese attacked vigorously, overrunning the division command post and causing the flustered 36th Division to fall back to the Salween. At dawn, the 53rd Army commander, Maj. Gen. Chou Fu-cheng, pushed a regiment across the Salween and restored the situation by attacking the Japanese flank. General Chou was an aggressive and tenacious fighter, whom his Manchurian soldiers had nicknamed Old Board-Back, and who had the reputation of never having yielded an inch to the Japanese. But even Chou could not immediately restore the morale of the 36th Division, which for some weeks took no further part in the Ta-tang-tzu fighting, and the rest of the 53rd Army had to bear the burden of clearing the pass.

In response to this, Lt General Zhou Fucheng of the 53rd Army pushed the 116th and 130th Divisions across the river to resume the advance towards Tiantouzhai. At the Mamien pass, the 592nd and 594th Regiments began clearing out the Japanese strongpoints while the 593rd Regiment moved west over mountain byways to emerge into the Shweli valley by the 16th, securing the western end of the pass and forcing Kurashige’s men to withdraw into the fortified village of Shangzhaigongfang. To the south, the New 39th would be able to secure Hemushu by the 17th. Yet the Japanese under Colonel Matsui Hideji soon recovered from the initial surprise of the Chinese offensive and the 1st battalion, 113th regiment drove the Chinese from Hung-mu-shu. The Japanese exploited their success and pushed the entire New 39th Division back against the Salween.

Further south, the 76th Division met outposts of the 1st battalion, 146th regiment and forced them back to the heights overlooking Ping-ka. Meanwhile the 88th Division from the north was fighting through a series of fortified villages as it headed south to join the 76th Division. By the 16th, thirteen villages were occupied in the area northeast of Ping-ka, but the Japanese, as they withdrew, received reinforcements. Strengthened by the 2nd battalion, 113th regiment, the Japanese did not attack the Chinese who were pursuing them, but moved south and hit the Chinese 228th Regiment south and west of Ping-ka.

Sensing the imminent danger from the north, Matsuyama redirected the 2nd and 3rd Battalions of the 113th Regiment to reinforce Shangzhaigongfang, where Kurashige would continue to resist staunchly. Reports from the American liaison teams were not cheerful. Americans observing the Kaolikung Range actions found that Japanese fire was accurate and economical, and that the enemy's use of camouflage and concealment approached perfection. The Japanese revealed no disposition to surrender though they were heavily outnumbered, often surrounded, and had neither air support nor air supply. On the other hand, the Americans reported that the Chinese endlessly wasted manpower and ammunition in costly frontal attacks. They reported that relations with the Chinese were not always as friendly as had been hoped, and they believed there would have to be better cooperation between Chinese and Americans if the Japanese were to be defeated. The Chinese were described as merely tolerating the Americans' presence and as paying little attention to their advice. The liaison personnel freely admitted their own shortcomings, and by their reports suggested that patience was the most important quality for a liaison officer to cultivate when dealing with the Chinese.

Matsuyama ha spread his forces widely, over a near 60 mile sector, thus he would be unable to perform mobile operations and was gradually shifting to a defense of the Kaolikung mountain range by the 20th. This allowed the 53rd Army to continue their advance and the New 39th to retake Hemushu. By late May, with the 198th Division apparently contained on the north, Kurashige then rushed with the 113th Regiment to reinforce the Tiantouzhai front, where they successfully stopped the 53rd Army on its tracks. Yet on June 1st, the 54th Army, emerged in the Shweli valley from Ta-tang-tzu pass to join the 593rd Regiment from the Ma-mien pass. Next day the Chinese occupied Chieh-tou village and began patrolling the Shweli valley. They took the advice of Y Force officers and donned Burmese clothes. So disguised, they found it easy to enter Japanese-held villages. When taken by surprise, the Japanese were willing to abandon many of their outer defenses. With TNT charges dropped by the 27th Troop Carrier's C-47's when the weather cleared, the 198th Division also blew up the last pillboxes at Chai-kung-tang on June 13th. When the last shots had been fired and the Chinese farmer boys of the 54th Army reported the area secure, there was bewilderment at finding only 75 Japanese bodies in defenses that must have been manned by at least 300 men, and shock and nausea when the Japanese kitchens revealed how the defenders had been able to prolong their stay. Pitiful and ghastly evidence showed that the Japanese had resorted to cannibalism when their rations failed. On June 14th the Japanese further quit Chiao-tou-chieh, leaving many stores to the 2nd Reserve and 36th Divisions. In the end, the Kurashige Detachment would pull back to Watien while the Inose Battalion retreated towards Kutungchieh.

General Wei then ordered the 71st Army to cross the Salween, just below the Huitung Bridge to attack Longling while a containing force attacked the strong Japanese harrison at Lameng. 20,000 troops of the 71st would cross the river by June 5th. At this time the 76th division left a regiment to besiege Pinga while the bulk pushed on to attack Matsuyama’s HQ at Mangshi, while the 9th Division crossed the Salween, cutting off Pingda’s line of communication. On June 4th, the new 28th Division attacked Lameng and forced Major Kanemitsu Keijirous garrison to retreat into the Mount Song fortress where they would hold out for several months. While the New 28th held down Kanemitsu, the 87th Division continued towards Longling, joining up with the 88th on June 8th to begin a siege of the main Japanese position on the Yunnan front. The Japanese still held onto the Burma Road east of Lung-ling, but as of June 7th the 87th Division had covered about two thirds of the distance along the Burma Road from the river to Lung-ling. The Chinese had to deal with small Japanese tanks, which had some moral effect but failed to halt the Chinese advance. Indeed, the latter had been fairly swift, for the Chinese had surprised the Japanese, and had been able to ease their supply problems by the capture of some Japanese rice depots.

To meet the new crisis, Matsuyama dispatched the 1st battalion, 119th regiment to stop the 2nd army at Xiangdaxiang and then attack Longling from the south. Matsuyama ordered Colonel Matsui Hideji to immediately relieve Longling from the north; and for the Yamazaki Composite Group to keep the Mangshi-Longling road open. Meanwhile, Lieutenant-General Song Xilian, had been making some progress against Longling’s two outer heights, the stout defenders would manage to repel the uncoordinated Chinese assaults for about a week. Four days of un-coordinated infantry attacks, with little artillery support, failed to carry the three mountains inside Lung-ling, and there was nothing to show for the heavy drain on the 71st Army's ammunition stocks. This gave more time for Matsuyama’s reinforcements to arrive by June 14th. On the 15th Matsui launched a heavy attack, in coordination with the besieged defenders, successfully defeating the 71st Army and consequently driving the Chinese from the vicinity of Longling. The Japanese had thus been able to drive back 10000 Chinese effectives by an attack with only 1500.

Repeated attempts by American liaison personnel with the 71st Army to learn how a small Japanese garrison could drive back a Chinese army group only brought embarrassed smiles from Chinese officers. The Chinese finally related on June 25th that the 261st Regiment had bolted, and that the commanding general of the 87th Division had attempted suicide. When fuller details of the fighting around Longling were available, anger and annoyance spread from Y Force to the Generalissimo himself. Y Force personnel considered the Chinese decision to withdraw from Longling inexcusable because the 11th Army Group had sent forward no reinforcements to meet the initial Japanese counterattacks. Of 21 battalions in the Longling vicinity on June 14th, only 9 took part in the fighting. In describing the defensive attitude of the 259th Regiment, as an example of the conduct that had cost the chance of a speedy breakthrough into Burma, one American liaison officer wrote: "From the time that we crossed the river until we reached Longling, the regimental commander continually had his troops in the rear digging emplacements and trenches in the fear that they would have to retreat." Yet that is it for the Yunnan battle for now as we need to head over to the Kamaing area.

General Tanaka’s 18th Division were withdrawing with the 22nd and 38th division in hot pursuit. To the south the Seton Roadblock was being held by 112th Regiment, threatening to thwart Tanaka’s plans. Coming to their aid, General Sun sent his 113th and 114th Regiments to descend upon Lawa, where General Aida began an unauthorized retreat on June 4th. The abandonment of Lawa severely affected the defense of Kamaing, thus General Aida was relieved of command and replaced with Colonel Imaoka Soshiro. Colonel Shoshiro immediately began to dig in at Lagawng. Meanwhile the bulk of the 55th and 56th regiments were holding onto the Nanyaseik area as General Liao’s 65th regiment cut their withdrawal route off on June 1st. While the rest of the 22nd Division were applying pressure from the north, the heavily outnumbered Japanese had no choice but to quickly cut a trail southeast, finally withdrawing on june 7th. Their retreat was chaotic, both regiments lost contact with each other and with their subordinate units as they made separate ways towards Kamaing. It would only be the 3rd battalion, 56th regiment who would arrive at Kamaing by June 10th, most of the others would reach Lakatkawng in late june. While retreating, their artillery units were intercepted by the pursuing Chinese and the artillerymen chose to die with their guns.

While the 22nd Division and 149th Regiment thus pushed towards Kamaing, General Sun had also sent the 113th Regiment to take Zigyun and the 114th Regiment to advance southwards and support the Chindit assault on Mogaung. The Chinese were able to encircle Kamaing from the west, north and east as the 149th Regiment then moving across the fields and into Kamaing to take the settlement on June 16th, pushing Tanaka’s battle-weary troops to the hills south and west of Kamaing. Meanwhile Brigadier Calbert was able to reach the Mogaung area by the start of June. 12 miles from Mogaung, Calvert’s forward troops began to run into Japanese patrols and snipers. Despite taking losses, the 3/6th Gurkhas led by Colonel Claude Rome, who in his previous incarnation had been overlord of “Broadway,” pushed on, seizing the western heights overlooking Mogaung on May 31. On June 1st, Calvert’s South Staffords linked up with Rome and the Gurkhas at the village of Loihinche. Other elements of the brigade reached the southern foothills of the heights, three miles south of the town, on June 2 and went straight into the fray. That same day, the Lancashire Fusiliers and the South Staffords also attacked Lakum (held by some ordnance troops and a field hospital). The leading force of Fusiliers was soon pinned down by heavy fire, the impasse only broken when a Bren gunner in the leading rifle section went wild, and ran “straight up the hill, firing from the hip and screaming curses at the Japanese.” Softening up the Japanese with airstrikes from Air Commando Mustangs, troops of the 1st Lancashire Fusiliers and 1st South Staffordshires attacked and wrested Lakum village away from Japanese and occupied the summit of the range of hills overlooking the city, to the northwest.

Calvert decided he would need to build a base akin to White City, where he could collect supplies and build an airstrip to take out the wounded. Calvert fixed his eye on the village of Lakum, occupying a strategic spot on the eastern foothills of the heights overlooking the Mogaung plain. Upon capturing the village, the Chindits would also find substantial ammunition, a field hospital and buildings which had obviously hosted several Japanese headquarters. The country leading up to Lakum, however, was hard stuff. It was in the midst of thick jungle intersected by deep ravines. The path proved difficult to follow as it sometimes wound along a ridge and sometimes went straight up or straight down. The place was a defender’s paradise. “A handful of resolute men could hold successive hill-tops for hours against a large force such as ours overburdened with mules and heavy stores,”.

In response to the new threat, Colonel Okada Hakuji rushed over with some units of his 128th Regiment to protect Mogaung, leaving his 1st Battalion to face the rapidly-approaching 114th Regiment and immediately recalling his 3rd Battalion from Seton. Alongside this General Honda ordered General Takeda to turn back from Myitkyina and instead secure the Moguang-Kameing area. Thus the chance to lift the siege of Myitkyina was lost. By June 3rd, the Chindits had built a new airstrip near the Tapaw Ferry, allowing airdrops of supplies and equipment to spill in. Calvert was now ready to launch his attack.

Early on June 8th, the 1st South Staffords set off to secure the Pinhmi. The village was defended by elements of 3rd battalion, 128th regiment who were also protecting some ammunition dumps in the area. The Staffords routed the Japanese and destroyed the dumps, clearing the way to the bridge. By now it was afternoon, and they stepped aside to let the 1st Lancashire Fusiliers move on to capture the 150-foot-long bridge. All seemed well until a hail of gunfire shattered the silence, tearing into the Fusiliers. Two companies were pinned down in the ditch while another was in the jungle further down. At about 6 pm, Calvert arrived at the front to confer with Major David Monteith of the attacking company. It was decided that two platoons, under the cover of a mortar barrage would dash across the bridge and secure the other bank. Calvert’s mind went to the 4.2” mortars. He intended to use them to deadly effect now. Two platoons of Fusiliers moved in on the bridge, with one platoon attempting to move along the ditch, only to struggle against the thick, waist-high grass, as the second slipped off the road into the jungle. The mortars, about 60 yards behind them, began firing, slowly at first, but then as fast as the men could drop bombs into the tubes. The men, with fixed bayonets, charged across the bridge. The Japanese waited until the British were halfway across before opening fire. Tracers filled that little space, bullets tearing into flesh. The Chindits toppled left and right. Some crawled in their bellies, trying to get just far enough to throw their grenades upon the enemy positions. By 6.15, it was all over, the retreat was called. Calvert summoned US airstrikes. Mustangs swooped in, bombing and machine-gunning the enemy emplacements, but one Mustang mistakenly bombed a group of Fusiliers unloading mules.

Because of the unexpected opposition, Calvert would instead direct his forces to ford the Wettauk Chaung and take Mahaung and Ywathitgale, which successfully fell on June 9. The following morning, a Gurkha company attacked towards Kyaingyi and the railway to create the impression that the main attack would come from this direction while the bulk of the 3/6th Gurkhas made a wide right flank advance to attack the bridge from the rear. At dawn on the 10th, Shaw’s Gurkhas moved forward, waist deep in marsh water and mud. The bridge assault party was under the command of Captain Michael Allmand, a one-time cavalryman commissioned into the Indian Army in 1942 after escaping from Singapore. Allmand moved his men forward warily. The approaches to the bridge were narrow with the road up on a high embankment with swampy, tree-heavy low-ground flanking both sides. Coming in from the marsh, the Gurkhas set upon the bunkers at the bridge with grenades and small-arms fire, but the Japanese held their ground. At 10 am, they tried again, shooting and hurling grenades from amid waist-deep mud of the Wettauk. Allmand, who was close to shore charged. Throwing grenades to scatter the enemy, he closed in to kill three with his kukri. Rallied by his heroism, the Gurkhas rushed the remaining defenders, capturing the bridge. About 35 Japanese were killed at the bridge and the Gurkhas captured one medium machinegun and two light machineguns. In return, Chindit casualties in the encirclement and capture of the Pinhmi Bridge came to about 130 killed and wounded. By mid-afternoon, Calvert had deployed two battalions up on the Mogaung-Pinhmi Road, while a third occupied the bridge area. Conquering the brigade saw the Chindits suffer 130 casualties, while Okada’s troops had also suffered heavy casualties, yet they had successfully delayed the Chindit advance for four days, which allowed Takeda to bring the bulk of his forces back into Mogaung.

Knowing full well that the Japanese had been able to reinforce Mogaung, Calvert decided to wait for the arrival of the Chinese troops that Stilwell had sent to reinforce him; but in the meantime, he launched a successful attack against the courthouse on June 11, followed by a failed advance towards the river. To secure his right flank, Calvert had decided to send a company of South Staffords under a new replacement officer, Major “Archie” Wavell Jr, son of the venerable Viceroy, to secure the area between the road and the Mogaung River. The Staffords made good headway, but near the river, they came under heavy fire from entrenched Japanese. Wavell was hit in the wrist, the bullet almost taking the hand off; and he was then pulled out of the line and walked back to the field hospital near Gurkha village, clutching onto his hand, which was now hanging on by a sinew. That night, the surgeons at Gurkha Village were to remove the hand entirely. Wavell Jr’s war was over. In the end, the Staffords also had to pull back towards the road after the loss of their commanding officer. By June 15th, the Chinese had still not appeared, thus the Chindits ultimately had to withdraw to Pinhmi.

Back over at Myitkyina artillery was arriving by air. Two batteries plus one platoon of 75-mm. howitzers; two 105-mm., and two 155-mm. howitzers, were landed. All except two pieces with GALAHAD were kept under headquarters control. During the siege they fired 600 tons of ammunition, very rarely with massed fire. Boatner renewed his offensive on June 13th, sending almost all his forces to attack the town from all directions. The American-Chinese forces would struggle to make much progress against General Minakami’s defenses. Utilizing a system of night attack and daylight defense, heavy casualties were consequently inflicted on the enemy and large supplies of weapons and ammunition were captured and used in the defense of the city. On June 12th the Japanese hit a platoon of K Company, New GALAHAD, so hard that the company broke and re-formed on the L Company line. The portion of the Japanese thrust that hit the perimeter next to the river made most of the men "take off," but two stayed in place and repelled the Japanese with an automatic rifle and a machine gun. To the west of this little break the Japanese worked their way in close but were stopped by grenades and small arms fire.

As a result of the attacks, however, the 3rd Galahad Battalion had cut the Maingna ferry road and reached the Irrawaddy north of Myitkyina by June 17th, with the 150th and 88th Regiments also gaining up to 200 yards. The allies needed to capture the Myitkyina-Mogaung-Sumprabum road junction; but for such few gains, Boatner had lost many men and thus had to stop his attacks on June 18th. Stilwell ordered the end of all infantry attacks. Boatner replied that he would stop attacking Japanese positions until ". . . our troops are steadied and a favorable opportunity presents itself." There was reason for the troops to need steadying. A and B companies, 209th Engineers, were cut off from their main body by infiltrating Japanese. Trying to close in on them, Company C and Headquarters and Service Companies were in turn halted by Japanese. The condition of A and B Companies became critical during June 14th, for they had only one meal with them. Two of their men managed to work their way back to the block on the Sumprabum Road with news of their plight, but enemy small arms fire prevented airdrops. The isolated companies finally made their way back in small groups to the rest of the battalion over 15 and 16 June. The 3rd Battalion of GALAHAD reported trouble in effecting reorganization and enforcing orders. The Americans were not alone in their problems. Two companies of the Chinese 2/42nd which had made a small penetration into the Japanese lines on 14 June were wiped out by counterattack that night. These setbacks emphasized the nature of the Myitkyina fighting. The Allies held a ring of battalion and regimental strongpoints enclosing a similar Japanese system. Though the Allied strongpoints were close enough for the troops in one to sortie to the aid of another should that be needed, they were not so close that interlocking fire could be put down to close the gaps. Consequently, there was plenty of room for maneuver and ambush, and the inexperienced engineers and New GALAHAD troops often suffered at the hands of General Minakami's veterans. On the other hand, the Myitkyina Garrison did not emerge entirely unscathed, as they too suffered heavily, losing approximately 1000 men during the month of June alone. But that is all for today with the CBI theater as we now need to head over to New Guinea to start the Battle of Lone Tree Hill.

After the fall of Wakde, General Tagami had sent Colonel Yoshino Naoyasu’s 223rd Regiment to cross the Tor River inland to attack Arare while Colonel Matsuyama Soemon’s 224th Regiment attacked the Toem area from the other side. In the meantime, General Doe’s 163rd Regiment patrolled across Tementoe Creek and the Tor River, encountering heavy Japanese resistance at Maffin but successfully repelling some enemy counterattacks. While the 163rd strengthened its defenses on the Tor and at Arare, Doe would also see the arrival of Colonel Prugh Herndon’s 158th Regiment on May 21. General Krueger’s plan was to use this regiment in a vigorous overland drive toward Sarmi, aimed at throwing the enemy into the defensive and therefore securing the Wakde area. This decision was based upon scanty and incomplete information concerning Japanese strength and dispositions. The Japanese had no intention of abandoning Sarmi and the two airstrips between the town and the Tor without a desperate struggle.

The Americans were also finalizing their plans for an operation against Biak, codenamed Hurricane. General Fuller’s plan was to land the 186th Regiment in the Bosnek area at 7:45 on May 27th to secure the Green Beaches and its two jetties. Once the two jetties were secured, LCI's bearing the 162nd Infantry, supporting troops, and the task force reserve were to move inshore and unload. LST's were also to move to the jetties when the beach area surrounding them had been cleared by the 186th Infantry. LCM's bearing artillery, tanks, and engineering equipment were to move to the beaches as soon as channels through the coral were found or made, or to the jetties in waves following the 186th Infantry's assault companies. As soon as it reorganized ashore, the 162nd Infantry was to advance rapidly west along the coast from Bosnek to seize the three airdromes. This drive was to be supported by eight tanks of the 603rd Tank Company and the 146th Field Artillery Battalion. The fields were to be repaired quickly to accommodate one fighter group and then expanded to receive an additional fighter group, a heavy bomber group, a reconnaissance group, a night fighter squadron, and one photo reconnaissance squadron. Mokmer Drome was to be the first field developed. Brigadier-General Edwin Patrick would also replace Doe in command of the Tornado Task Force, as the latter would resume its duties as assistant commander of the 41st Division.

Admiral Fechteler’s Task Force 77 was to provide naval support and cover the assault shipping. Naval fire support was to begin at H minus 45 minutes, 6:30. From that time until H Hour, cruisers and destroyers were to expend 400 rounds of 8-inch, 1,000 rounds of 6-inch, 3,740 rounds of 5-inch, and 1,000 rounds of 4.7-inch ammunition on targets in the airfield area west of the landing beaches. After H Hour the cruisers were to continue intermittent fire on the airfields, bombard targets of opportunity, and respond to calls for support from the forces ashore. Because there were many known or suspected Japanese gun emplacements along the south shore of Biak, counterbattery fire was to take precedence over all other types of fire. Bombardment of the landing beaches was also to begin at H minus 45 minutes. Five destroyers were to bombard the beaches and adjacent areas until H minus 30 minutes, when they were to move westward to join the cruisers firing on the airfield area. Then four other destroyers were to continue beach bombardment until H minus 3 minutes. Total ammunition allowance for beach bombardment was 4,900 rounds of 5-inch and 4.7-inch shells, while 40-mm. and 20-mm. ammunition was to be expended at the discretion of individual ship commanders. Rocket and automatic weapons fire from three rocket-equipped LCI's and two SC's was to provide close support for the assault waves. This fire was to begin at H minus 5 minutes and was to last until H Hour or until the initial wave was safely ashore.

Meanwhile General Kenney would toss 52 B-24’s to bomb the beaches just before the landings. Additionally, medium bombers and fighters from 5th Air Force would cover the force from the air; and from May 17th onwards, the bombings on Biak’s airfields would increase sharply in violence to soften up its defenses. As elsewhere along the absolute defense zone perimeter, primary emphasis was laid upon the construction of airfields. Between December 1943 and the enemy invasion of Hollandia in April 1944, two of three projected fields on southern Biak were completed and put into operational use by planes of the Navy's 23rd Air Flotilla. Their usefulness ended almost immediately, however, when the enemy's vastly superior air forces began operating from Hollandia bases. As in the Wakde-Sarmi sector, the concentration of effort on airfield construction until the Hollandia invasion resulted in dangerously delaying the preparation of ground defenses against enemy amphibious attack. In the five weeks which elapsed between the Hollandia and Biak invasions, the Biak garrison forces, under able leadership and by dint of desperate effort, succeeded in organizing a system of strong cave positions, which proved highly effective after the enemy landing. However, time, equipment and manpower were so short that defensive preparations could not entirely be completed. Some 15-cm naval guns, brought to Biak immediately after the Hollandia invasion to strengthen the coast defenses, were still unmounted when the island was attacked.

On May 23rd, the 158th advanced west from the Tor River Bridgehead. The advance of Company L met increasingly strong resistance. Japanese defenses were centered around three small, brush-bordered lakes near the beach about 1,800 yards west of the Tor. The rest of the 3rd Battalion, 158th Infantry, across the Tor before 1130, quickly moved forward to assist Company L, which had been pinned down along the main coastal track west of the lakes by Japanese machine gun and rifle fire. Company K pushed up to the left flank of Company L, while Company I moved toward L's rear. With the aid of mortar fire from the 81-mm. weapons of Company M, Companies K and L were able to push gradually forward during the afternoon, advancing on a front about 400 yards wide. Finding that the attack was not progressing as rapidly as he had expected, Colonel Herndon ordered his 1st Battalion across the Tor. The 1st Battalion did not start moving until 1400 and could not get far enough forward to join the attack before dark. Tanks would probably have been of great help to the 3rd Battalion, but by the time the mediums of the 1st Platoon, 603rd Tank Company, moved across the Tor, the forward infantry troops had already halted for the night. In the end, Companies L and K would dig in for the night across the main coastal track about 400 yards east of Maffin.

The following morning, after an ineffective mortar and artillery bombardment, Herndon resumed the attack. Despite the lack of extended artillery support, Companies K and L moved out as planned at 7:30. Company L, on the right, advanced along the beach encountering only scattered rifle fire but Company K, on the main road, had hardly started when Japanese machine gun and rifle fire from concealed positions in a wooded area on the left front halted its advance. Unable to gain any ground, Company K called for tank support. Two tanks, together with a flamethrower detachment from Company B of the 27th Engineers, arrived at Company K's lines about 1000. With the flamethrowers and tanks blasting the way, the infantrymen overran the Japanese defenses, killing ten of the enemy and capturing two machine guns. The remainder of the Japanese force, probably originally some forty men strong, disappeared into the jungle south of the road, whence scattered rifle fire continued to harass Company K. Company L reached the outskirts of Maffin No. 1 about 1400. The movement had been slow, not as a result of Japanese opposition but because the battalion commander did not believe it prudent for Company L to advance far beyond Company K. Despite the return of two companies, most of Colonel Kato’s engineers would have to withdraw behind the Tirfoam River against such heavy firepower. Captain Saito’s reconnaissance unit, meanwhile, retreated to the jungles south of Maffin alongside one engineer company, which was under Kato himself.

Over the Tirfoam River, however, the Americans were again stopped by the tenacious engineers, which again forced Herndon to request tank support. As the tanks moved into position elements of the Right Sector Force, comprising Captain Saito's men of the 1st Battalion, 224th Infantry and an engineer company, charged out of the jungle. The Japanese were under Colonel Kato, Right Sector Force commander, who was killed as he personally led a small detachment against the American tanks. The enemy was quickly thrown back with heavy losses by the combined fire of the four tanks and Company L's riflemen and machine gunners. However, under cover of their infantry attack, the Japanese had dragged a 37-mm. anti-tank gun forward out of the jungle. As the enemy infantrymen withdrew to the southwest after the death of Colonel Kato, the anti-tank gun opened fire. It was soon destroyed and its crew killed, but not before three of the American tanks had been so damaged that they had to be withdrawn for repairs.

Facing such heavy resistance, Herndon then sent his 1st Battalion to carry out a deep envelopment to the south across the Tirfoam, yet these troops would similarly be unable to break through by nightfall. After killing 28 men and wounded 75 others, Kato’s force allowed Tagami to dispatch the 2nd Battalion, 223rd Regiment to reinforce the Ilier Mountains line. On the morning of May 25, Major Matsuoka Yasake also arrived there with an infantry company to assume command of the remainder of Kato’s forces. Meanwnhile Yoshino had crossed the Tor River, 3 days behind schedule and to the east, Matsyuama was assembling on the right bank of the Tementoe River. Herndon relieved his 1st Battalion with the 3rd and then pushed west with the 2nd Battalion following behind them. The next objective for the 158th was Long Tree Hill.

Lone Tree Hill, known to the Japanese as Mt. Ilier, had been named for a single tree which was depicted on its crest by the map then employed by the Americans. Actually, the hill's coral mass was covered with dense rainforest and jungle undergrowth. Lone Tree Hill was about 175 feet high, 1200 yards long north to south, and 1100 yards wide east to west. The north side dropped steeply to a rocky shore on Maffin Bay. The hill's eastern slope was fronted by a short, violently twisting stream which was promptly dubbed the "Snaky River" by the 158th Regiment. The main road curved away from the beach to pass south of the Snaky River and Lone Tree Hill through a narrow defile. The southern side of this defile was formed by two noses of Mt. Saksin , a terrain feature about 100 feet higher than Lone Tree Hill. The more westerly of these noses was named "Hill 225", known to the Japanese as Mt. Sento after its height in feet. No name was given to the eastern ridge line, which pointed toward Lone Tree Hill from the southeast. There was a small native village at the eastern entrance to the defile and another at the pass's western outlet. Mt. Saksin was a name given to an indefinitely outlined hill mass which forms the northern extremity of the Irier Mountains, extending inland from the coast at Lone Tree Hill. The name Saksin was specifically applied to a prominent peak about 2,000 yards due south of Lone Tree. On or about May 23rd General Tagami had moved his headquarters into the Mt. Saksin area, apparently on the southwest side of the central peak.

Herndon forces continued the advance through the abandoned enemy positions, albeit without tank support, for they could not cross the fragile Tirfoam bridge. In the afternoon, the Americans were finally halted below the southernmost bend of the Snaky River, subjected to heavy machine-gun fire and an intermittent artillery bombardment. General Patrick, who had succeeded to the command of the TORNADO Task Force during the morning, was informed of the opposition encountered by the 1st Battalion. He ordered the advance stopped for the night and instructed the 158th Infantry to remain well east of the Snaky River so that American artillery could register on the native village and the defile without endangering the forward troops. Harassed by a few artillery shells, which by now had been recognized as originating from Japanese 70-mm. or 75-mm. weapons, the 1st Battalion pulled back about 500 yards east of the Snaky. A perimeter was set up with the battalion's left resting on the road and its right on the beach. The 2nd Battalion established a series of company perimeters back along the road to the east. Casualties for the day had been 22 men killed and 26 wounded, almost all in the 1st Battalion, while about 50 Japanese had been killed. When the attack orders for the day had been issued, it had been hoped that the 1st Battalion could reach the top of Lone Tree Hill before nightfall. Since the unexpectedly strong enemy opposition had prevented the realization of this hope, plans were made to continue the advance westward on the 26th. The ultimate objective was the east bank of the Woske River, 2,000 yards west of Lone Tree Hill, and the intermediate objective was the native village at the eastern entrance to the defile. The advance was to be preceded by naval shelling of the northern slopes of Lone Tree Hill from 6:30 to 7:00. A fifteen-minute artillery preparation was also to precede the advance, and the infantry was to start moving at 8:45.

The next morning, naval fire started ten minutes late. Two destroyers lying offshore shelled the northern slopes of Lone Tree Hill and the Maffin Bay area, firing on known or suspected enemy defensive positions and assembly points. After a twenty-minute bombardment the two support vessels withdrew. Artillery fire did not begin until 8:30. The time lag gave the Japanese ample opportunity to prepare for the infantry attack which had been heralded by the destroyer fire. The artillery, aiming its shells into the defile and against the eastern slopes of Lone Tree Hill, ceased firing about 8:45. A few moments later the 1st Battalion, 158th Infantry, Company B again leading, started moving westward. The infantry's line of departure was nearly 1,000 yards east of the village at the southeast foot of Lone Tree Hill, and the advance had to be slow because the road ran through heavily jungled terrain. The enemy therefore had sufficient time to reoccupy positions in the defile and on Lone Tree Hill which might have been vacated during the American artillery barrage. The value of both the naval and artillery bombardment had been lost.

Herndon’s 1st Battalion moved once again against Lone Tree Hill. Company B moved forward to the point at which it had been held up the previous afternoon and was again stopped--this time by fire from the southeastern corner of Lone Tree Hill. Company D's heavy machine guns were brought up to spray a densely wooded area in front of the point rifle platoon. The fire dispersed the Japanese riflemen, and Company B moved forward again. Less than 100 yards of ground had been gained when the company again encountered machine gun and mortar fire originating in the native village. Company A, initially off the road to the right rear of Company B, turned north to the mouth of the Snaky River. One platoon crossed at the river mouth at 1030 but was quickly forced back to the east bank by Japanese machine gun fire from the rocky beach below the north face of Lone Tree Hill. Artillery support was called for, supplied, and proved successful in stopping the enemy fire, and about 1:50 all Company A crossed the Snaky. Orders were to move down the west side of that stream to establish contact with Company B and to send one platoon up the eastern slope of Lone Tree Hill to probe enemy positions. Other efforts were meanwhile being made to scatter the Japanese opposing Company B. Company E moved up to the left flank of Company B and on the south side of the main road. The combined efforts of the two rifle companies proved insufficient to dislodge the Japanese from their positions at the eastern entrance to the defile, and the enemy fire forced the American units to seek cover. Company F was therefore ordered to pass through B's left flank and proceed to Hill 225 to take the Japanese positions from the rear. Company F's attack could not be started before dark and Company A, moving up the west side of the Snaky, was unable to relieve much of the pressure on Company B. Finally, Company A was forced for a second time to withdraw to the east bank of the river as a result of enemy fire from Lone Tree Hill. Tanks would have been of great help to Company B, but the bridge over the Tirfoam could not bear their weight, and the road west of the stream was in such disrepair that tanks probably could not have negotiated it.

Only Company A would manage to cross the Snaky River through much effort, yet it would be unable to relieve the pressure from Company B’s front and would have to retreat by the end of the day. To prevent further casualties from being inflicted by Japanese patrols, which were expected to roam around the flanks of the forward elements during the night, a semicircular perimeter was ultimately established. Although Herndon’s attacks on May 26th had been completely unsuccessful, the 158th Regiment had located and probed some of the principal Japanese defenses in the area and could now be ready to launch a more effective assault.

General Vinegar Joe was experiencing some major setbacks, but it looked like Myitkyina was as good as his. However the American officers' reports of how difficult the going was for the Chinese was quite disheartening. Over in New Guinea, the allies were yet again faced with a great obstacle, now in the form of One Tree Hill.

- 149 - Pacific War Podcast - Japanese Triumph in China 26 - October 4 - , 1944
24 sep· The Pacific War - week by week
Last time we spoke about the battles for Peleliu and Angaur. Following the amphibious assaults on Peleliu and Anguar, US Marines under General Rupertus intensified their offensive. On September 17, Colonel Hanneken’s 7th Marines advanced in Peleliu's southern sector, as the 1st and 5th Marines pushed north, confronting the fortified Umurbrogol Mountains, where Colonel Nakagawa’s defenses stalled their progress. Despite reaching key positions by mid-morning, intense Japanese counterattacks continued, causing heavy casualties. On September 18, the 7th Marines, aided by armor, resumed their slow advance, securing the southern part of Peleliu by day's end. Meanwhile, the 1st and 5th Marines faced brutal combat in the central ridges, suffering significant losses. By September 21, the capture of nearby Ulithi Atoll provided a strategic base for future operations. Despite securing important positions, the Marines encountered severe resistance in the Umurbrogol Mountains, leading to high casualties and necessitating reinforcements. By September 23, the Americans secured footholds on Peleliu and Anguar, yet fierce fighting persisted in Nakagawa’s fortified positions.

This week we are picking up back over on Peleliu and Anguar where the Japanese are still providing stiff resistance. On September 23, Colonel Venable’s 322nd Regiment had made little progress breaking into the Lake Salome bowl. With their commanding officer severely injured, a change in tactics was imminent. On the morning of September 24, propaganda broadcasts over a public address system were used to try and persuade the remaining Japanese to surrender. However, only two Japanese soldiers surrendered, reporting that over 300 defenders remained in the bowl under Major Goto. This accurate estimate was disregarded by the American command, who believed only about 150 defenders remained. Following this failed attempt, all available artillery bombarded the bowl in preparation for an attack from the north, altering the appearance of the bowl's interior and rims to aid the upcoming assault. Back at Peleliu, after heavy bombardment, Colonel Dark’s 321st Regiment resumed its advance north along the coast on September 24, despite continued harassment from Japanese fire from the central ridges. By noon, they had secured the trail-road junction south of Garekoru. Some troops explored the trail to the east, encountering heavy resistance, while Company G advanced rapidly north through Garekoru, reaching the O-4 Line. Behind them, Dark’s 3rd Battalion and Colonel Hanneken’s 3rd Battalion also pushed northwards. Further east, the 7th Marines pressed against Colonel Nakagawa’s main defenses on the Umurbrogol Mountains. By nightfall, having successfully resisted Japanese counterattacks on O-4, General Rupertus’ northward drive had proven to be a significant success.
He next planned to cut across the island on September 25 through the eastern trail to completely isolate the Japanese forces in the Umurbrogol ridges. At 07:00, Dark’s troops began moving eastward, with Company E successfully reaching the edge of East Road against light opposition. They halted in front of Hill B, which dominated the eastern area. However, the 3rd Battalion encountered heavier resistance from pillboxes and emplacements protected by steep walls and sheer cliffs guarding the northern approaches to the Umurbrogol defense system, making little progress. Meanwhile, to the north, a strong tank-infantry patrol advanced about 1,200 yards, killing 30 Japanese and destroying four pillboxes and two large supply dumps before reaching the O-5 Line. The weak resistance encountered by the patrol suggested that remaining Japanese strength was concentrated in the Umurbrogol Pocket. Thus, at 10:30, Rupertus decided to commit the 5th Marines for a drive to the northern tip of Peleliu. Rapidly relieved by the 1st Marines on eastern Peleliu.
Orders to move to the western portion of Peleliu found the 5th Marines in static positions on Eastern Peleliu, where the regimental mission had been to prevent enemy counterlandings. The 1st Battalion was deployed in the vicinity of the radio direction finding station near Ngardololok, the 2d Battalion was holding the islands north of the northeastern peninsula, while the 3d Battalion, less one company, occupied defensive positions along Purple Beach. The 1st Marines completed the relief of the 5th shortly after noon and assumed command of the 5th Marines sector at that time. In order to expedite movement of the regiment to the West Road, the battalions moved out on trucks at 1300, with 1/5 in the lead, followed by 3/5 and 2/5.
By 1600, the 5th Marines had executed the passage of the lines, and the regiment passed through Phase Line O-4 near Garekoru. As 1/5 continued its advance up the West Road, it encountered erratic resistance from what appeared to be Japanese holdouts. The level terrain was devoid of the dense jungle growth abounding elsewhere on Peleliu and offered ideal conditions for the movement of tanks and LVT flamethrowers accompanying the advance battalion. Aside from occasional Japanese sniper and mortar fire, the advance continued for about 500 yards without interruption to Road Junction 15, where the West and East Roads met. This vital point was defended by a small Japanese force, which had installed itself on a ridge dominating the road forks. Around 1700, as the Marines approached this point, the enemy opened fire, which served only to delay the Marines. When the firefight ended the Japanese had lost 20 killed. The battalion continued its advance for another 100 yards and seized the Japanese radio station, whose towers the forward elements of RCT 321 had spotted on the previous day. Having secured this objective, the battalion established night defenses north of the radio station from the beach to the high ground east of the West Road. Upon reaching Road Junction 15 in the wake of the advance of 1/5, the 3d Battalion pivoted to the southeast and headed down East Road, where it established night defenses on the road and along the western slopes of Hill 80. The latter hill, in itself an isolated terrain feature, owed its importance to its location, for it was the only link separating the Kamilianlul ridges to the south from the Amiangal ridges, which formed the northernmost hill mass on Peleliu.
Throughout the evening and night, the forward elements at the radio station were continuously and heavily attacked and bombed but managed to hold against the enemy onslaught. Meanwhile, at Angaur, after a heavy and prolonged artillery bombardment, the 3rd Battalion, 322nd Regiment pushed forward to launch its assault from the north. Finding no route south over the cliffs, they assembled near the northern end of the Milwaukee Railroad for an attack west the following day. At 07:30 on September 26, the infantry launched their assault on Lake Salome, quickly taking control of the eastern rim with minimal resistance. Facing increasing enemy fire, the Americans made their way down the eastern rim to the bowl floor. However, by the end of the day, they were halted by Goto’s positions on the northern cliffs and "The Island," a gap between an overgrown coral mound and the eastern rim. To the south, the 2nd Battalion supported the attack by advancing north, capturing the southeast rim and clearing out several enemy cave positions.
Back over on Peleliu the Marines had a very rough night full of Japanese infiltrator harassment. In fact our old friend Eugene Sledge wrote about the night of September 25th and what his unit of K Company, 3rd battalion, 5th marines went through.
The Japanese who had come across the road in front of me were probably members of what the enemy called a “close-quarter combat unit.” The enemy soldier shot by Sam was not dressed or equipped like their typical infantryman. Rather he wore only tropical khaki shorts, short-sleeved shirt, and tabi footwear (splittoed, rubber-soled canvas shoes). He carried only his bayonet. Why he entered our line where he did may have been pure accident, or he may have had an eye on our mortar. His comrade angled off toward the right near a machine gun on our flank. Mortars and machine guns were favorite targets for infiltrators on the front lines. To the rear, they went after heavy mortars, communications, and artillery. Before Company K moved out, I went down the road to the next company to see what had happened during the night. I learned that those blood-chilling screams had come from the Japanese I had seen run to the right. He had jumped into a foxhole where he met an alert Marine. In the ensuing struggle each had lost his weapon. The desperate Marine had jammed his forefinger into his enemy's eye socket and killed him. Such was the physical horror and brutish reality of war for us.
The 1/5 spent the early hours of 26 September in consolidating its positions around the radio station and preparing for continuation of its attack later in the day to the northern tip of Peleliu. Shortly after 0600, 3/5 jumped off for an attack against Hill 80 with Company K on the left and Company I on the right. The attack carried the hill and by 0830 the assault force reached a swamp bordering the east coast of Peleliu. This advance of the 3d Battalion was of major importance because it effectively cut the island in two. Late in the afternoon most of the battalion moved back from Hill 80 to a reserve position near the junction of East and West Roads. The unit's southern flank extended south from the junction along East Road to Hill 80, where Company I was stationed for the night. Between Company I, 5th Marines, and the 2d Battalion, 321st Infantry, at Hill B, lay a gap approximately 1,800 yards long through which only the 321st Infantry's Neal Task Force had passed. In this gap lay 1,500-yard-long Kamilianlul Mountain, held by an unknown number of Japanese and as yet not even reconnoitered by American units. The 5th Marines consolidated their positions and resumed their assault.
The 1st Battalion, 5th Marines, ran into stiff opposition from the Amiangal ridges dominating northern Peleliu. The northern portion of the L-shaped hill system consisted of ridges running generally from northeast to southwest for about 1,000 yards; the southern leg extended from northwest to southeast. The southern leg of the ridges was not continuous but broken into four separate hills or knobs, designated from northwest to southeast as Hill 1, Hill 2, Hill 3, and Radar Hill, so named because it had at one time served as an enemy radar installation. These four knobs were to gain ill repute as Hill Row. The entire Amiangal ridge system was held in strength by the Japanese, particularly the portion paralleling the route of advance of 1/5. This part contained some of the most elaborate caves and tunnels on Peleliu. The battalion had barely started out along the West Road when the enemy in and on Hill 1 opened up on the Marines with 37mm and 75mm guns as well as automatic weapons and mortars. This curtain of fire from the Amiangal ridges was reinforced by heavy fire from Ngesebus Island. All forward movement soon halted. Attacking eastward from the West Road, Company B assaulted the second knob, Hill 2, but also encountered opposition. Through sheer determination the company was able to gain a firm foothold on the hill by early afternoon. This accomplishment in effect served to outflank the Japanese on Hill 1, but Japanese resistance on the last mentioned hill continued throughout the day. An attempt by Company C to seize all of Hill 1 during the remaining hours of daylight was unsuccessful, and continuation of the assault had to await the following day. During the bitter fighting in which 1/5 engaged during the night of 25-26 September and for most of the following day, 2/5 remained stationary on the southern flank of the regiment. At 1600 on 26 September, when it had become apparent that 1/5 could make no further progress, 2/5 was ordered to attack. The battalion advanced northward through the left wing of 1/5, carefully bypassing embattled Hill 1. In the course of its advance, the battalion drew heavy fire from Japanese emplacements in the plain, from the ridges on its right, as well as from Ngesebus. Enemy mortars proved especially troublesome. As a result of the heavy fire, Company F lost four of its supporting tanks before it had advanced very far beyond Hill 1. Attempts by the artillery to give all possible support to the battalion were largely ineffectual. "We fired frequent missions throughout the day on these mortars; the reported effect was that the mortars were neutralized while we fired but that they were not destroyed. The enemy apparently withdrew into the caves during the period of our fire." As evening approached, the 5th Marines occupied a jagged front line. The 1st Battalion, though out of contact with the 2d, was tied in with the 3d on the right. The mission of the 3d Battalion was to support either the 1st or 2d Battalion in the event of a major Japanese counterattack. Further progress of the 2d Battalion was impeded by a large antitank ditch, which blocked the approach to the remnants of the Peleliu phosphate plant. The Japanese had converted the reinforced concrete foundation of the otherwise demolished structure into a major defensive installation. Exposed to the enemy fire from Ngesebus Island and plunging fire from caves and defensive positions from the hills, 2/5 found itself in a very unenviable situation.
Further south, after some necessary adjustments, Dark’s forces assaulted Hill B with two battalions. Initially repelled, Dark then sent a task force led by Captain George Neal to attack from the north. After a complex maneuver north and then south, the Neal Task Force attacked Hill B just as other elements of the 321st fought their way to the top through challenging terrain. The hill eventually fell to the Americans, completing the isolation of the Umurbrogol Pocket. By the end of the day, the island was divided in two places, leaving Nakagawa’s determined defenders isolated in two major pockets. On September 27, with the Umurbrogol Pocket now contained, the 5th Marines continued their operations against Amiangal Mountain. At the same time, the 1st Battalion, 321st Regiment advanced north from the Hill B area to close the long gap along East Road up to Hill 80. Dark's infantrymen secured Kamilianlul Mountain with minimal resistance and then moved towards the Marines’ road junction.
The 2d Battalion was to find progress extremely rough for the remainder of the day. First, the erstwhile phosphate plant, which the Japanese had turned into a blockhouse, had to be secured in an area that bristled with snipers. The problem confronting Colonel Harris was a formidable one. The blockhouse in front of 2/5 could not be taken until the antitank ditch blocking the approaches to it had been seized. This was a job that the infantry could not tackle without armored support. The regimental commander decided to utilize all arms available in reducing these obstacles. First of all, Colonel Harris called naval gunfire and artillery in on Ngesebus and any other targets suspected of harboring artillery or mortar positions. A medium tank, equipped with a bulldozer blade, was pressed into service to level the antitank ditch, and filled it by 0830. A LVT flamethrower then was able to come within effective range of the Japanese fortification. Moments later, when the flame and smoke had cleared, all resistance from this stronghold had ceased and more than 60 dead Japanese remained in the rubble. While this action was in progress, patrols from Company E seized a small, weakly defended ridge abutting the road from the east. The 2d Battalion thereafter resumed its advance northward along the road as well as over the adjacent ridge. Company F, at the head of the column, soon found itself embroiled in some of the most bitter and frustrating action of the entire campaign. Aside from receiving heavy Japanese artillery and mortar fire, the company faced a series of pillboxes and field fortifications on level ground, and layer upon layer of caves in the hillsides. Even though they were not aware of it at the time, the men of the 5th Marines had come upon the most skillfully constructed defenses on Peleliu. The Japanese Army had utilized all of the many natural caves possessing tactical value, adapting them for the emplacement of heavier weapons with great ingenuity. On the other hand, Japanese naval troops had preferred to construct their own caves with the help of the 214th Naval Construction Battalion, composed of men who had been professional miners and tunnel workers in civilian life. Since most of these Navy caves were located near the northern end of Peleliu, they proved a serious obstacle to the advance of the 5th Marines. Eugene Sledge faced these obstacles and saw firsthand the effectiveness of flamethrowers. Here is a passage from him:
Burgin's order to us to continue firing into the opening interrupted my musings. We kept up a steady fire into the pillbox to keep the Japanese pinned down while the flamethrower came up, carried by Corporal Womack from Mississippi. He was a brave, good-natured guy and popular with the troops, but he was one of the fiercest-looking Marines I ever saw. He was big and husky with a fiery red beard well powdered with white coral dust. He reminded me of some wild Viking. I was glad we were on the same side. Stooped under the heavy tanks on his back, Womack approached the pillbox with his assistant just out of the line of our fire. When they got about fifteen yards from the target, we ceased firing. The assistant reached up and turned a valve on the flamethrower. Womack then aimed the nozzle at the opening made by the 75mm gun. He pressed the trigger. With a whoooooooosh the flame leaped at the opening. Some muffled screams, then all quiet. Even the stoic Japanese couldn't suppress the agony of death by fire and suffocation. But they were no more likely to surrender to us than we would have been to them had we ever been confronted with the possibility of surrender. In fighting the Japanese, surrender was not one of our options.
Sheer courage and heroism in themselves proved inadequate for the task. In the course of the morning of 27 September, Company F seized the two ridges forming the northwestern anchor of the Amiangal system and established observation posts on the crests. But this did not solve the problem of what to do about the Japanese occupying the caves about half way up the hill. Marine casualties mounted steadily, and evacuation of the wounded became more and more difficult. Since the cave openings completely dominated the road leading past the northernmost ridge of Peleliu, the advance of the entire 2d Battalion ground to a halt. The first tank attempting to squeeze through the narrow gap between the hill and the northwestern shore was hit, and the Marines occupying the crest of the hill were powerless to cope with the caves underneath.
Although the Americans now controlled the northern shore and blocked further enemy reinforcements, skilled Japanese miners continued their resistance underground. What the Marines did not know was that they were facing the most comprehensive cave system on Peleliu which was the underground home of the Japanese naval construction units who were, luckily for the Marines, better miners than infantrymen. The Japanese Army had utilized all of the many natural caves possessing tactical value, adapting them for the emplacement of heavier weapons with great ingenuity. On the other hand, Japanese naval troops had preferred to construct their own caves with the help of the 214th Naval Construction Battalion, composed of men who had been professional miners and tunnel workers in civilian life. Since most of these Navy caves were located near the northern end of Peleliu, they proved a serious obstacle to the advance of the 5th Marines. In the end, it would take weeks for the Marines to finally quash all resistance on Akarakoro Point, then only by blasting closed all the tunnel entrances, sealing the Japanese defenders inside to their fate.
To the south, Harris’ 1st Battalion pressed on with their attack on the mountain's southern leg, successfully capturing Hill 1. Meanwhile, the 322nd Regiment resumed its assault on the Lake Salome bowl, fighting to secure the base of the north rim but encountering less resistance in the south as most Japanese defenders had been evacuated towards Romauldo. The following day, despite a successful enemy mortar barrage that initially forced a temporary withdrawal and reorganization, the Americans cleared the entire bowl floor of Japanese troops, isolating Goto’s remaining forces in the Romauldo area. This progress enabled the 322nd to launch a final coordinated attack on October 1, with its three battalions trapping the enemy in the Romauldo Pocket, though they were unable to penetrate Goto’s final defenses.
On September 28 at Peleliu, while Dark’s 1st Battalion engaged Japanese infiltrators while mopping up the Kamilianlul Mountain area, Harris’ 1st and 2nd Battalions continued their assault on Amiangal and successfully captured Hill 3. This action isolated the remaining Japanese forces at Radar Hill. Meanwhile, the 3rd Battalion, 5th Marines executed a successful landing on Ngesebus Island with minimal resistance after a comprehensive artillery, air, and naval bombardment.
The curtain on the drama of Ngesebus opened on the morning of September 28, when the massed fire of five artillery battalions from Peleliu, as well as heavy fire from warships and aircraft, blanketed the island. Near the northwestern shore of Peleliu, an impressive gathering of high-ranking officers had assembled to witness the operation. The group included such notables as Admiral Fort, and Generals Julian C. Smith, Geiger, Rupertus, Mueller, Oliver P. Smith, and Bell. The weather was cool and cloudy and interspersed with frequent rain squalls. For the Corsair pilots of VMF-114, air support for the Ngesebus landings represented a very interesting and original assignment. The operation marked the beginning of combat work for the squadron, which had reached Peleliu only two days earlier. At 06:30, the Corsairs hit the airstrip on Ngesebus with 500-pound bombs and strafed the entire island as well as Kongauru to the northeast. "Strafing runs were made just a few feet off the deck and a hail of lead laid all over the island." At 08:40, 20 Corsairs preceded the landing craft and gave the island another heavy strafing. In the course of this attack, Japanese mortar positions were spotted and one especially prominent square blockhouse with an iron door was fired on and neutralized. Whenever aircraft were not directly over the island, the artillery on Peleliu and naval guns offshore gave Ngesebus a heavy going over, starting at 07:00 and concluding at 09:05. Both quick and delay fuzes were used. Observers reported that the island was completely covered with fire. In the course of the preliminary bombardment, naval gunfire ships pounded the northern portion of Ngesebus and continued to fire on that part of the island throughout the landing.
The Marines advanced inland, swiftly securing the airstrip and the eastern portion of Ngesebus. One platoon then landed on Kongauru and Murphy islands to secure them against light opposition. However, the attack to the northwest encountered strong resistance from Japanese forces entrenched in caves and dugouts, prompting the deployment of tanks to support the Marine assault. By 5:00 PM, nearly all of Ngesebus was under American control, with only a few hundred yards at the extreme northwestern tip remaining in Japanese hands and some caves on the ridges still needing to be cleared.
The 3d Battalion spent a relatively quiet night on Ngesebus. On the morning of 29 September, Companies I and K resumed the attack. Progress was normal until the two companies had nearly reached the northern tip of Ngesebus, when a 75mm gun opened up at point blank range. The Marines quickly destroyed this weapon and went on to overcome the rest of the resistance on the island. At 1500, 29 September, Ngesebus was declared secure. An hour later, 2/321 relieved the Marines and completed mopping up. Having accomplished the mission on the island, 3/5 returned to Peleliu. The battalion had secured the island at a cost of 15 killed and 33 wounded. In return, the Marines killed or captured 470 Japanese. Infantrymen of 2/321 were to account for another hundred of the enemy during the ensuing mop-up. Eugene Sledge wrote this about the final capture of Ngesebus:
The next morning, again with the help of tanks and am-tracs, our battalion took most of the remainder of Ngesebus. Our casualties were remarkably low for the number of Japanese we killed.* In midafternoon we learned that an army unit would relieve us shortly and complete the job on the northern end of Ngesebus. Our mortar section halted to await orders and dispersed among some open bushes. In our midst was the wreckage of a Japanese heavy machine gun and the remains of the squad that had been wiped out by Company K. The squad members had been killed in the exact positions to be occupied by such a squad “according to the book.” At first glance the dead gunner appeared about to fire his deadly weapon. He still sat bolt upright in the proper firing position behind the breech of his machine gun. Even in death his eyes stared widely along the gun sights. Despite the vacant look of his dilated pupils, I couldn't believe he was dead. Cold chills ran along my spine. Gooseflesh tickled my back. It seemed as though he was looking through me into all eternity, that at any instant he would raise his hands—which rested in a relaxed manner on his thighs—grip the handles on the breech, and press the thumb trigger. The bright shiny brass slugs in the strip clip appeared as ready as the gunner, anxious to speed out, to kill, and to maim more of the “American devils.” But he would rot, and they would corrode. Neither he nor his ammo could do any more for the emperor.
The rest of the 5th Marines continued their operations on September 29, launching a full-scale assault on Radar Hill using flamethrowers, bazookas, and demolition charges, finally capturing the position by the morning of September 30. Following the completion of operations in northern Peleliu, the 5th Marines were relieved by the 321st Regiment. However, as the Army troops took over, the remaining Japanese, who had been hiding underground, reoccupied some positions, requiring two additional days of fighting to fully secure northern Peleliu. Nonetheless, the Japanese presence in Peleliu had now been reduced to Nakagawa’s Umurbrogol Pocket, so Peleliu was officially secured. Total losses during this battle so far included 843 killed, 3845 wounded and 356 missing of the 1st Marine Division; 46 killed, 226 wounded and 7 missing from the 321st Regiment; and an estimated 9076 Japanese dead plus 180 prisoners of war. Yet that is all for today with Peleliu and Anguar as we now need to travel to China where the Japanese are still carrying out Operation Ichi-Go in an effort to capture Guilin and Liuzhou.
As we last observed, General Yokoyama's 11th Army had taken control of Lingling Airdrome and Quanzhou by September 14. Following this, they reorganized their units in preparation for resuming their offensive in October. Meanwhile, the 34th Division was deployed towards Changning, and the 37th Division moved to capture Shaoyang, which fell by the end of the month. The 23rd Army also made final preparations for their offensive in early September. General Tanaka directed the Kawakami Raiding Unit in a wide flanking maneuver along the Zhukeng-Huaiji road towards Wuzhou, while the 23rd Independent Mixed Brigade embarked on a long march north to Guiping. On September 13, the 22nd Independent Mixed Brigade and the 22nd and 104th Divisions began their main advance towards Wuzhou. However, the Kawakami Raiding Unit successfully captured Wuzhou on September 22 and seized the Danzhuzhen airfield six days later. Each unit then continued its advance westward to Guiping, which fell to the 23rd Brigade on October 11. So far, Tanaka’s forces had encountered little to no resistance, but this was about to change.
After the war, in discussing the performance of the Chinese divisions supposed to defend Guilin and Liuzhou, the political situation in east China, and the attitudes of the east China commanders, Marshal Hata remarked that in his opinion Li Zongren and Bai Chongxi had kept their forces out of serious fighting in order to conserve them "for the future." At the time, there were rumors that these men were planning a coup against Chiang Kai-Shek. Chinese resistance was light, but with its supply situation improved the 14th Air Force again did its best on the Salween as well as in east China. In all September the force dropped 1897.6 tons of bombs and fired 1281382 rounds of machine-gun ammunition, some of the latter of course at aerial targets. In early September, Japanese fighter reinforcements from the homeland also entered combat. The Japanese were pleased at the performance of the latemodel fighters with one of the air regiments they sent to China. Thanks to the air cover thus supplied, for the first time in the east China campaign they found themselves able to move supplies regularly on the Xiang Jiang, which paralleled their line of advance, and so thought their prospects "brightened."
At the beginning of the month, Yokoyama renewed his offensive, with the 58th Division successfully taking Xing’An and the 34th Division capturing Changning. The 37th Division was then deployed to Dao, and the 34th Division was sent to Xing’An in preparation for the final push toward Guilin. On October 20, this attack commenced as Yokoyama directed the 216th Regiment to advance to Lehecun, the 58th Division to assault the area north of Guilin, the 40th Division to move to Gaoshangzhen, the 13th Division to advance to Quanhuicun, and the 3rd Division to push toward Fuchuan. With minimal resistance from the retreating Japanese forces, most of these movements were completed by the end of the month. The 3rd Division pushed further to Pingle, while the 37th Division occupied Gongchengzhen and Yanshan to approach Guilin from the south. On November 3, the 3rd Division captured Lipu and began preparations for the advance towards Liuzhen, encircling Guilin and opening the route to Liuzhen.
Meanwhile, on October 22, Tanaka ordered the reinforced 23rd Brigade to continue its advance toward Guigang, with the 104th and 22nd Divisions pushing toward Wuxuan. Their progress, previously unopposed, was now challenged by the Chinese 46th and 64th Armies, which launched daily attacks against Guiping with substantial air support. As a result, the 22nd Division was redirected to counter the Chinese forces, successfully forcing their withdrawal by October 29. Following this victory, the 23rd Brigade captured Guigang on November 3, and the 104th Division seized Wuxuan the following day. This allowed Tanaka’s forces to begin a northern pursuit to support Yokoyama’s assaults on Guilin and Liuzhen.
After the third Anshan strike, General LeMay began implementing reforms within the 20th Bomber Command. These changes included reorganizing the command, enhancing the logistics system, adjusting target priorities, and improving coordination with Pacific operations. As a result, the frequency of missions increased each month, with each mission becoming more substantial and effective. Concurrently, following the successful completion of the newly renamed Isley Field on Saipan, the 73rd Bombardment Wing was redirected to the Marianas instead of the CBI Theater. There, it would join Major-General Haywood Hansell’s 21st Bomber Command, tasked with executing high-altitude, daylight precision attacks to cripple Japan's aircraft industry.
The XXI Bomber Command arrived on Saipan on October 12, 1944, and from the start General Hansell was beset by a host of serious command problems, the worst of which were continued teething problems with the B-29, tardy delivery of aircraft, aircrews untrained in high altitude formation flying, primitive airfield conditions, lack of an air service command for logistical support, no repair depots, a total absence of target intelligence, stubborn internal resistance to daylight operations by his sole combat wing, subordinates in the XXI Bomber Command who lobbied for his removal, and Hansell's inferiority in rank in dealing with other AAF commanders in the theater. Furthermore, Hansell was soon prohibited from flying combat missions with his command, possibly because of limited knowledge of the atomic bomb or the perception that he knew the existence of Ultra.
As plans for a sustained bomber offensive against Honshu progressed, the strategic focus of Operation Matterhorn diminished. The 20th Bomber Command shifted to flying missions in direct support of other Pacific operations, with target priorities moving from coke ovens to the aircraft industry. In preparation for the upcoming invasion of the Philippines, the command was tasked with two closely spaced maximum missions against Okayama in Formosa, totaling 170 sorties, along with very-long-range reconnaissance missions. Yet now we have to travel over to the India-Burma theater. As the advance towards the Chindwin continued and the resilient 33rd Division finally crossed the river in late November, General Katamura was finalizing his plans for a withdrawal to the Mandalay sector, scheduled for December. This decision was driven by the intense pressure the British 36th Division was putting on General Takeda’s defensive positions at Pinwe, forcing the defenders to prepare for a final retreat by the end of November. Meanwhile, General Slim was preparing for Operation Capital. He planned to stretch airpower to its limits to move four and two-thirds divisions across the Chindwin, along with two tank brigades. After establishing bridgeheads at Sittang, Mawlaik, and Kalewa, he intended to cross the Chindwin and confront General Kimura’s forces between the Chindwin and the Irrawaddy. The 4th Corps, now under the experienced General Messervy, would break out from the Sittang bridgehead, advance east through the mountains, capture Pinlebu, and then approach the Shwebo plain from the north. Simultaneously, General Stopford’s 33rd Corps would move from Kalewa, following the Chindwin southeast to Yeu and Monywa. Once the Japanese forces were pushed onto the open plain, Slim planned to exploit his overwhelming advantage in airpower and tanks to decisively defeat them, anticipating that the enemy would fiercely defend Mandalay.
The combination of the defeats at Kohima, Imphal, Mogaung and Myitkyina meant that by the autumn of 1944, Kimura’s role was reduced to defending southern Burma as the northern flank of their new ‘South-East Asia defense zone’. With few reinforcements or supplies to look forward to, Kimura had grim prospects. On paper he had ten divisions (2nd, 15th, 18th, 31st, 33rd, 49th, 53rd, 54th, 55th, & 56th), though this was really seven, since little remained of the three divisions that had been devastated at Kohima-Imphal. He also had the dubious support of Bose’s INA and Aung San’s seven-battalion Burma National Army, but the civilian population was increasingly going over to the side of the likely winners. Unexpectedly, Kimura received 30000 fresh troops in the period June–October, but his problem was more commissariat than raw numbers, since he was rapidly running out of supplies. Even those he had (45000 tons of food, 500 lorries and 2000 pack animals) were difficult to get to the front, and Kimura was painfully aware that the situation could only get worse. The South-East Asia zone was slowly being throttled by the Allied naval blockade, all approaches to Rangoon were mined, and in 1944 total Japanese shipping losses amounted to 2.3 million tons. Even those ships that ran the blockade would proceed no farther than Penang in Malaya.
Kimura chose to deploy smaller units to delay the British-Indian forces while the main body of the 15th Army retreated across the Irrawaddy River. His strategy was to launch a counterattack once the British crossed the river, aiming to replicate a reverse Imphal by wearing down the British-Indian forces through attrition and then destroying them during their retreat in the May 1945 monsoon. Meanwhile, Admiral Mountbatten was also seeking a victory of his own. On November 8, he ordered an assault on Japanese positions in Arakan, with a deadline set for the end of January. This operation was assigned to General Christison’s 15th Corps.

The fighting on Peleliu and Angaur raged asAmerican forces struggled against resilient Japanese defenses. Significant advances were made, including the isolation of the Umurbrogol Pocket and the capture of Ngesebus Island. Despite heavy casualties, Peleliu was eventually secured, leaving a small pocket of Japanese resistance.

17 sep· The Pacific War - week by week
Last time we spoke about the invasion of the Palau Islands. General Rupertus’s 1st Marine Division was tasked with attacking Peleliu, while General Mueller’s 81st Division would land on Angaur. Prior to the landings, extensive neutralization of Japanese airfields was carried out by Allied forces. On September 6, carrier-based aircraft attacked the Palaus, significantly damaging enemy targets but encountering minimal resistance. The invasion fleet, led by Admiral Fort, began landing operations on September 15. Despite strong Japanese defenses, especially around Peleliu’s rugged coral ridges, the Marines made some progress but faced intense resistance. Notable figures such as Eugene Sledge, author of “With the Old Breed,” provided personal insights into the brutal conditions faced. The landing saw heavy casualties and challenges, including ineffective pre-landing bombardments and fierce counterattacks, but the Marines managed to secure key positions by the end of the first day. The 81st Division then proceeded with landings on Angaur on September 17, facing lighter resistance but difficult terrain.

Last time we left off, Peleliu and Anguar had just been amphibiously assaulted by US Marines. While the landings on Angaur were underway, General Rupertus pressed on with the Peleliu offensive on September 17. In the southern sector, Colonel Hanneken’s 7th Marines made headway against the isolated Japanese defenders. The 3rd Battalion cleared a minefield and captured the southeast promontory, while the 1st Battalion took on the southwestern promontory but only managed to secure half of it due to fierce enemy resistance. To the north, the 1st and 5th Marines advanced further, encountering the Umurbrogol Mountains for the first time, where Colonel Nakagawa had fortified his defenses. On the left flank, Colonel Puller’s 1st and 3rd Battalions encountered minimal opposition as they moved along the relatively flat coastal plain but had to halt their advance when the 1st Battalion was impeded by a reinforced concrete blockhouse. On the right, Colonel Harris’ 2nd Battalion progressed well while staying hidden from Japanese artillery and mortar fire. However, despite reaching their objectives by mid-morning, Harris’ 1st Battalion faced difficulty when Puller’s 2nd Battalion, after making initial gains, was halted by the Umurbrogol defenses. They fought hard to secure Hill 200 but were immediately met with fire from the next ridge. Additionally, Harris’ 3rd Battalion was pinned down by heavy flanking fire from the left. That night, additional armor was sent to the 7th Marines to support the ongoing operations in the south. The next morning, Hanneken’s 3rd Battalion launched a final assault. During the night of D+2, additional armor (tanks and 75mm gun-mounted halftracks) was brought up and at 10:00 on September 18 the advance was resumed. Again progress was painfully slow with many reserve elements being attacked by Japanese from bypassed caves and underground emplacements. At 13:44 elements of Companies A and C reached the southern shores, though the area being assaulted by Company B was still heavily defended. Tank support had withdrawn to re-arm and before Company B was in a position to resume the attack, a bulldozer was needed to extricate the gun-mounted half-tracks, which had become bogged down. At that time, several explosions were heard from the Japanese defenses and it was found that remaining Japanese defenders had finished the job for the Marines. The final handful leaped from the cliff tops into the sea in an effort to escape, only to be picked off by Marine riflemen. With the taking of the two promontories, the southern part of Peleliu was secured. 1/7 and 3/7 squared themselves away for a well-earned rest, while headquarters reported "1520 hours D+3, 7th Marines mission on Peleliu completed." Unfortunately, this was not quite the case. Despite the slow progress and intense Japanese resistance, the Marines managed to secure the southern portion of Peleliu by the end of September 18.
At the same time, the 1st and 5th Marines continued their fierce and costly push north. On the right flank, Colonel Harris’s 2nd Battalion faced only sporadic resistance as it cut through the dense jungle. The Americans eventually reached a causeway leading east to Peleliu’s northeastern peninsula, a potentially dangerous obstacle to their advance. After a successful patrol, Harris opted to call in an airstrike before crossing, but the strike missed its target and hit the area while the Marines were crossing. Despite this, the bridgehead was established, though further casualties were incurred due to friendly artillery and mortar fire. With this new foothold, Harris redirected his 3rd Battalion eastward across the causeway to support the 2nd Battalion’s advance. On the left flank, the 1st Marines, having sustained 1,236 casualties, were urged by Rupertus to "maintain the momentum." This led Colonel Puller to commit all available reserves, including engineers, support personnel, and Hanneken’s reserve 2nd Battalion. The 1st Marines suffered about 240 casualties during the 17th and in Japanese counterattacks the ensuing night; the 3rd Battalion was reduced to about one third of its original strength; and two companies of the 1st Battalion were practically finished as fighting units. On the other hand, there was some reason for optimism. Progress on the 17th had been measured in hundreds of yards in the rough, high ground at the southern end of the central ridges and strong Japanese resistance had been overcome. Whatever optimism may have existed was not to last too long. On the 18th, in what the Marine Corps' history of the operation characterizes as "savage and costly fighting," elements of the 1st and 7th Marines managed to advance more than 500 yards in the center, principally along the ridge lines and hills oriented north and south. But the advance during the day was held up at a group of peaks which seemed at first to form a continuous ridge line that was oriented more east and west than the rest of the Peleliu ridges. Soon, the name Five Sisters came to be applied to a cluster of peaks forming the western side of the terrain feature. A towering hill at its eastern extremity, separated from Five Sisters by a saddle, was designated Hill 300, or Old Baldy. With the 7th Marines held up in the center, at Five Sisters, the units on both sides of the central ridges halted so as not to create exposed flanks. Puller’s 3rd Battalion made progress along the coastal plains but had to pause to stay in contact with other units. Meanwhile, the 2nd Battalion struggled against the Umurbrogol Mountains, capturing Hill 210 before being forced to withdraw due to a fierce Japanese counterattack on Hill 200 behind them. At Anguar, following a three-hour artillery bombardment supported by aircraft, General Mueller’s 321st and 322nd Regiments resumed their advance north and west with tank support. After linking their advances, Colonel Venable pushed west and reached the high ground where Major Goto had established his main defenses, while Colonel Dark made significant progress south until his forces encountered the formidable defenses at Green Beach.
The night of 18-19 September was noisy and nerve-racking all along the front and few troops got much sleep. Minor Japanese attacks harassed the exposed salient held by the 3d Battalion, 322d Infantry, while bats and large land crabs helped the Japanese to create distraction and started troops firing on nonexistent enemy infiltrators. Apparently no casualties resulted either from Japanese action or indiscriminate small arms fire. Friendly artillery fire did, however, cause some casualties. About 2030, four or five 105-mm. shells from the 316th Field Artillery Battalion hit the lines of the 2d Battalion, 321st Infantry, killing 4 men and wounding 15 others. The artillery fire was stopped before further damage could be done.
On September 19, following a night of numerous Japanese infiltrations and small-scale counterattacks, the 322nd Regiment swiftly secured Saipan Town and advanced to the north shore of Garangaoi Cove. Meanwhile, the 321st Regiment successfully attacked and captured the Green Beach fortifications from their vulnerable side. To manage the exposed Japanese forces on the beaches, Dark’s 2nd Battalion, supported by tanks, maneuvered left and progressed down the southwest of the island, halting just short of the shoreline by nightfall. At Peleliu, Harris’ Marines made headway towards the Ngardololok area, overcoming light resistance and quickly dispatching the few enemy stragglers they encountered, reaching Purple Beach by day's end. However, in front of the O-3 line, Puller’s weary troops, having endured a grueling night of Japanese counterattacks, resumed their assault on the Umurbrogol Mountains.
Despite some local advances, by evening on 20 September the 1st Marines had been stopped and, ". . . as an assault unit on the regimental level, had ceased temporarily to exist," having suffered almost 1,750 casualties, well over half its strength. Relief was absolutely necessary, not only because casualties were heavy but also because the survivors were physically exhausted from heat, lack of water, and continuous combat. Elements of the 7th Marines therefore relieved all 1st Marines units except those along West Road. While the 7th Marines took over from the exhausted 1st Marines on the right, the 5th Marines continued their advance through western Peleliu, securing its two peninsulas, including Island A and Ngabad Island, by September 21. General Mueller, concerned lest the Japanese reported on the south break through gaps or weak points in the forward lines, had special defenses in depth set up at RED and BLUE Beaches, utilizing Shore Party and antiaircraft troops. All units were alerted to expect Japanese attacks during the night. The division expected (and perhaps hoped) that the Japanese still believed to be located in southern Angaur might launch a suicidal desperation charge during the night or at dawn on the 20th. The night proved very quiet until, toward morning, some small, scattered Japanese parties infiltrated through the lines of both regiments. There was no banzai effort--rather, these Japanese troops were apparently attempting to escape to the northwest hill mass from positions in the mangrove swamp and GREEN Beach 3 areas. Action at dawn was limited to a mopping-up operation directed against four Japanese discovered in the headquarters area of the 2d Battalion, 321st Infantry. By 11:00 on September 20, Mueller reported to General Geiger that all organized resistance on Angaur had ended and that the island was secure.
General Mueller's statement was probably prompted by his realization that the remaining Japanese were compressed into the northwest hills and by the reports that about 850 of the enemy had been killed through the 20th. This casualty figure was an overestimation. Probably fewer than 600 Japanese had been killed through the 20th, and Major Goto still had possibly 750 men with which to conduct an organized defense in the northwest. On orders from General Inoue, Goto planned no final banzai attack which would decimate his forces. Instead he withdrew over half his force to rugged terrain and emplaced them in natural or prepared fortifications. His lines of defense in the northwest were well conceived; many of his positions were mutually supporting; the amphitheater configuration of the bowl provided him with defensive areas whence heavy cross fires could be directed at attackers; the broken coral, with its crevices, fissures, caves, and ridgelets, gave him defensive advantages at least as good as those at the Ibdi Pocket on Biak; and he had available a number of artillery and anti-tank weapons, heavy and light mortars, and heavy and light machine-guns, most of them so emplaced as to give maximum support to his riflemen. In addition, he could still exercise effective control over the men he had gathered in the Lake Salome bowl. For whatever it was worth, Goto was ready to conduct a protracted defense, though the best he could hope for was to tie down the 322nd Regiment. Nevertheless, the real issue at Angaur--securing the prospective airfield area--had already been decided.
To the north, while southern Angaur was being secured, Venable’s men were probing the enemy's northwestern defenses with a series of company-sized attacks. These attacks allowed the Americans to gather crucial information about Goto’s remaining positions, centered around the Lake Salome bowl. Venable discovered that organized resistance was still strong, prompting him to rearrange his units for a final push. Following a heavy artillery and air bombardment, the 322nd Regiment attacked the bowl with tank support, initially making some gains but soon encountering obstacles due to the terrain and enemy fire. By the end of September 21, Venable deemed the newly gained positions too exposed and decided to withdraw to the previous night's defenses. Meanwhile, the 1st and 7th Marines continued to face heavy casualties as they fought through the Umurbrogol Mountains, with the latter advancing less than 175 yards after two days of intense combat. Nakagawa’s fierce defenders managed to halt the 1st Marine Division on the rough and well-defended terrain, resulting in a total of 4,000 casualties by this time. After visiting the front, Geiger decided to replace the battered 1st Marines with Dark’s 321st Regiment, which had suffered minimal casualties and had completed its mission at Angaur. The 1st Marines by this time reported 1749 casualties. One Marine later described the fighting in the Umurbrogol, which attests to the level to which the 1st Marines had deteriorated: "I picked up the rifle of a dead Marine and I went up the hill; I remember no more than a few yards of scarred hillside, I didn't worry about death anymore, I had resigned from the human race. I crawled and scrambled forward and lay still without any feeling towards any human thing. In the next foxhole was a rifleman. He peered at me through red and painful eyes. I didn't care about him and he didn't care about me. As a fighting unit, the 1st Marines was finished. We were no longer human beings, I fired at anything that moved in front of me, friend or foe. I had no friends, I just wanted to kill."
OnSeptember 19, he also dispatched Colonel Arthur Watson's reserve 323rd Regiment to secure Ulithi Atoll. After a successful reconnaissance mission, the infantrymen landed on September 22, discovering that the atoll’s airfield and seaplane base had been abandoned by the Japanese. The Americans later established a major advanced fleet anchorage, a Marine airbase, and a Navy seaplane base there. Ulithi Atoll contained a 300-berth anchorage and a seaplane base. Occupation of these Western Caroline islands provided still another base from which future operations against the enemy could be supported. The construction of an airstrip on Ameliorate Island made possible fighter plane protection for the anchorage and afforded a base from which US aircraft could continue neutralization of the nearby Japanese bases on Yap. Together with Angaur and Peleliu Islands to the southwest and Guam, Tinian, and Saipan to the northeast, the capture of Ulithi Atoll completed a line of American bases that isolated Japanese holdings in the Central and South Pacific. The occupation of Ulithi Atoll further denied it to the enemy as a fleet anchorage, weather and radio station, and possible air and submarine base, in addition to precluding its use by the enemy to observe and report the activities of American forces in the sector. By September 25 the unloading of all the support ships had been completed and Vice Admiral John H. Hoover, Commander, Forward Areas Western Pacific, took over the task of developing Ulithi Atoll into an advanced fleet base. Within a month after its capture, more than 100 Navy craft from self-propelled types to lighters, floating drydocks, barges, landing craft, and seaplane wrecking derricks were en route to the island. During subsequent operations in the Philippines, the Pacific Fleet found Ulithi to be an extremely valuable base. Prior to the invasion of Okinawa, the island served as a staging area for fleet and amphibious forces. The atoll thus fulfilled a vital strategic role in the final phase of the Pacific War.
On that day, Venable resumed his assault on the Lake Salome bowl. The coastal offensive faced little resistance, but the attack through the southern defile encountered heavy enemy fire. Despite this, the troops reached the shores of Lake Salome. However, Venable was severely wounded during the action and had to be evacuated, with his troops retreating to more defensible positions by nightfall. The main strength of the attack was placed on the right (southeast) section of the bowl, and tanks fired along the eastern rim about 200 yards in front of the leading elements. The mediums had been undisturbed by enemy fire all morning, but, apparently attracted by an incautious grouping of officers and men near the lead tanks and defile exit, a Japanese anti-tank gun opened fire from a hidden emplacement along the east rim. Three officers (including Colonel Venable, who was in the forward area to observe the new attack) and one enlisted man were severely wounded and had to be evacuated. During the retirement on the 22nd, one of the three forward tanks was so badly damaged by a mine or buried shell that it could not be moved through the defile. This tank blocked the defile's northern entrance and prevented the withdrawal of another medium, which had to be destroyed to keep it from falling into Japanese hands. In four days of fruitless effort to push into the bowl from the south, three tanks and two 75-mm SPM's had been lost. Heavier infantry losses also began to be sustained now that the Japanese, cornered, were fighting to the death. On that day, for instance, the 2nd Battalion lost 2 men killed and about 35 wounded.
At 0730 on the morning of the 23d, the 2d Battalion, with Companies B, C, and E attached, continued the attack into the bowl from the south. Companies B and C worked up the east shore of Lake Salome. Companies I and G pushed toward the southwest and western shores, while Company F paid particular attention to caves along the southwest rim of the bowl. During the first part of the attack all companies moved forward rapidly, and Company I reached the northwest corner of the lake without much trouble. But Company B, pushing forward against increasingly heavy Japanese fire from the north, was pinned down by this fire when it reached the northeast corner of the lake. Company C was sent north on B's right to try to outflank the enemy machine gun and mortar positions from which the fire on Company B originated. The intention was to flush the Japanese from their positions and push them southwest and south against the main body of the 2d Battalion. But Company C could make little progress toward the northern section of the bowl, and its own position became precarious as Japanese mortar and machine gun fire increased and the 1st Battalion's own 81-mm. mortar ammunition ran out, making further mortar support impossible. Japanese fire continued to increase and the positions of all forward companies became untenable. A general withdrawal to the defile entrance was ordered. The withdrawal was painfully slow; companies were broken up; all units suffered more casualties. One small group of Company I, separated from its parent unit, worked over the cliffs and ridges at the bowl's western rim to the coast at BLACK Beach. Company B, retreating in small segments, lost men as it withdrew from the northeast corner of the lake. All told, the 2d Battalion and attached companies lost 18 men killed and over 75 wounded during the day.
Concurrently, as the 1st and 7th Marines continued to struggle with the formidable Umurbrogol Mountains, Harris’ Company G successfully secured the undefended Carlson Island, finally completing the 5th Marines' original mission. Despite concerns about a potential enemy attack on Koror and Babelthuap after the Peleliu operation, General Inoue decided to reinforce Nakagawa’s beleaguered garrison. By 21 September effective Japanese infantry strength in the central ridges was down to 1,300 men. That, of course, does not paint a true picture of the situation in the central pocket. A trained soldier, well armed, can be tenacious on the defense in such terrain as the central ridges of Peleliu whether or not he be trained for infantry service. There were probably 4,000 Japanese troops (including the 1,300 infantrymen) still firmly ensconced in the central pocket as of 21 September, and there were at least 1,000 more troops in the Amiangal Mountain area at northern Peleliu. Nevertheless, Colonel Nakagawa, commanding the Peleliu Sector Unit, clearly needed reinforcements if he was to hold out much longer. There were perhaps 30,000 Japanese troops in the northern Palaus to draw from, including two battalions of the 59th Infantry, two battalions of the 15th Infantry, and four or five recently organized infantry battalions of the 53d Independent Mixed Brigade.
The Japanese were not to reach their destination undetected. At 0535, the destroyer H.L. Edwards spotted seven enemy barges about 1,000 yards northeast of Akarakoro Point at the northern tip of Peleliu, obviously headed for the island. The destroyer opened fire, sinking one barge before the remainder reached the beach. A combination of bombing and strafing, naval gunfire, and artillery hit the barges on the beach, and by 0845 the cruiser Louisville reported all barges destroyed. The enemy version of this incident agrees only in part with the American account, adding that "despite receiving severe enemy air and artillery fire at a point two kilometers off the coast, they made a successful landing at 0520 hours under the command of 1st Lieutenant Murahori".
Knowing that some Japanese forces had reached Peleliu, Rupertus decided to deploy his own reinforcements between the central ridges and the western shore, targeting the enemy's weak spot for an offensive up the western coast. The 7th Marines supported the Army by attacking enemy positions from the south and center, with Hanneken’s 3rd Battalion advancing along the high ground to the right rear of the 321st. After relieving the 1st Marines, Dark sent patrols up the coastal flat to Garekoru, encountering little opposition initially. However, Dark’s 2nd Battalion faced heavier resistance in the afternoon and had to retreat, postponing the northward advance until the next day. During the night, Inoue sent the remainder of the 2nd Battalion, 15th Regiment, and despite being shelled, most reinforcements reached Peleliu. By September 23, the Americans had secured important footholds on Peleliu and Angaur. However, intense fighting remained, with the 321st Regiment relieving the 1st Marines against Nakagawa’s fortified positions, while the 322nd Regiment continued to attack Goto’s defenses on the northwest hills. Yet that is it for the Palau’s as we now need to turn to Mortai.
General Persons’ troops quickly secured and expanded the island perimeter, successfully repelling the enemy's night raids with little difficulty. An example of these raids is the September 18 attack. This is the Japanese report: “On 18 September the main body of the 2nd Provisional Raiding Unit, which had moved into position along the upper Tjao, launched a strong night infiltration attack with the objective of disrupting the enemy's rear area in the vicinity of Doroeba and Gotalalmo. Although deep penetration of the enemy lines was achieved and considerable casualties inflicted, the attack failed to reduce the beachhead or to interfere with the enemy's rapid preparation of Doroeba airfield.” In truth, the Americans easily repelled this attack, suffering very few casualties. These raids would continue throughout September and October.
American engineers were busy constructing a new fighter strip at the Pitoe Drome area. This strip was scheduled to be ready for use by September 29 but was eventually abandoned and downgraded to an emergency field. A number of factors influenced the decision to abandon the site, which was renamed Pitoe Crash Strip. Japanese air reaction had been so ineffectual that the need for a fighter base on Morotai was not as urgent as had been expected. Aircraft based on escort carriers, some of which remained in the Morotai area for weeks, were able to keep away most of the Japanese planes, and their efforts were supplemented by long-range land-based fighters from Sansapor. Moreover, the line of approach which planes had to use to land on Pitoe Crash Strip interfered with that of the more important bomber base at Wama Drome. Finally, the terrain at the crash strip was by no means as well drained as that at other locations on the Doroeba Plain, and it was necessary to expend much engineer effort to keep the strip operational.
The new field, which acquired the designation Pitoe Drome, was located about 1,200 yards north of Wama Drome. Construction proceeded slowly at Pitoe Drome because so much engineer effort had to be devoted to the completion of Wama Drome. By 4 October almost 7,000 feet at the new site had been cleared, but it was not until the 17th, D plus 32, that even one runway was surfaced, let alone taxiways and dispersal lanes. Meanwhile, the construction of a new bomber field at Wama Drome faced significant delays due to heavy rainstorms and a shortage of suitable surfacing material. Despite almost constant struggles with soggy ground and tropical downpours, engineers managed to make 4,000 feet of Wama Drome operational by October 4. However, the overall progress on building Morotai’s new airbase, intended for the upcoming invasion of the Philippines, was slower than anticipated. Nevertheless, the Tradewind Task Force was disbanded on September 25, as the island was considered secure enough. General Hall then assumed command of the Morotai base as the commander of the 11th Corps. However, unbeknownst to the Americans, who believed the only possible Japanese response to the invasion was the ineffective air raids already carried out against them, troops in Halmahera were preparing to embark on a dangerous mission to reinforce Morotai and contest control of this key island.
In the meantime, after the successful invasion of the Palaus, new developments were unfolding on the Philippines front following Admiral Mitscher’s Task Force 38's recent successful strikes. These strikes had revealed an unexpected vulnerability in the enemy's air defenses, prompting Admirals Halsey and Nimitz to cancel the Yap operation, thereby freeing up many resources for the Philippines Campaign. Approximately 500 aircraft, or about 57% of the 884 believed to be in the Philippines, were rendered nonoperational or destroyed during these air attacks. Consequently, General MacArthur decided to cancel the preliminary Mindanao operations and instead make a direct jump from the Palaus-Morotai line to Leyte on October 20. Shortly after this change in schedule, MacArthur informed the Joint Chiefs that he could advance from Leyte to Luzon by December 20, two months earlier than planned. Meanwhile, the carrier raids on Mindanao and the Visayas strengthened the Southern Army command's belief that the Allies were preparing for an early invasion of the Philippines. As a result, Marshal Terauchi recommended accelerating the reinforcement of the Philippines, activating Operation Sho-Go, and authorizing the 4th Air Army to employ its main strength against enemy carrier task forces. This was in contrast to the current policy of not committing available air strength against enemy raiders, which was failing to conserve Japanese air power for a decisive battle. However, Tokyo denied these last two requests while also receiving concerning reports about General Kuroda’s neglect of his duties as field army commander. In the middle of September, IGHQ decided to replace General Kuroda with General Yamashita. Not only did General Kuroda have a concept of the Philippine operations that differed from that of his superiors, but he was charged with neglecting his duty as field army commander. Lt. Col. Yoshie Seiichi of the Personnel Bureau of the War Ministry, who had been sent to the Philippines to investigate personnel matters in the Southern Army, said of the incident: “Stories reached the War Ministry that Lt. Gen. Kuroda was devoting more time to his golf, reading and personal matters than to the execution of his official duties. It appeared that his control over staff officers and troops was not sufficiently strong and that there was a good deal of unfavorable criticism of his conduct among the troops. There were also indications that discipline was becoming very lax. On September 4, I left Tokyo under orders . . . to investigate. As a result I obtained many statements substantiating the unfavorable stories in regard to Lt. Gen. Kuroda. The recommendations of all the staff was that Lt. Gen. Kuroda be relieved as soon as possible, and be replaced by Gen. Yamashita . . . who was a superb tactician and excellent leader.” Random note, for those interested, over on my personal podcast at the Pacific War Channel I did a single episode covering how Yamashita became the Tiger of Malaya and plan to do more pieces on him as I find him to be one of the more interesting generals of the Pacific War.
Before an effective change in command could take place, the Japanese were about to experience a more dramatic display of Allied offensive power that they would soon encounter in the Philippines. On September 18, Mitscher’s Task Force 38 was ordered to head back toward the islands for a major strike against Luzon, the heart of Japanese control in the Philippines. The American carriers achieved complete surprise and successfully attacked Luzon three days later. Despite the fierce defense by approximately 42 Zeros, between 09:30 and 18:00 on September 21, four waves of over 400 aircraft targeted the harbor area and airfields around Manila with bombs and strafing runs. The assault on the harbor and shipping along the west coast resulted in the sinking or severe damage of 34 vessels totaling over 100,000 gross tons, while the raids on the airfields inflicted significant damage on grounded aircraft. At 0610 the following day, 22 September, search planes discovered the enemy carrier groups still lurking off the coast of Luzon, and at 0730 a hit-and-run attack was carried out by 27 Japanese aircraft, with reported bomb hits on two carriers and one cruiser. Naval air units at Legaspi attempted to carry out a second attack on the enemy carriers during the late afternoon, but the attack force of 19 planes failed to locate the carrier groups. Following the failed Japanese hit-and-run counterattack, Mitscher continued his assaults on Manila, destroying an estimated 110 aircraft in the air and 95 on the ground, and sinking or damaging 44 vessels. After the apparent withdrawal of enemy carriers, the Japanese decided to relocate their remaining ships in Manila Bay to other anchorages, many of which were directed to the secure docks of Coron Bay. However, Mitscher’s carriers returned on September 24 to launch further strikes against Luzon, including a raid by about 96 Hellcats and 24 Helldivers on Coron Bay, which resulted in the sinking or damaging of 10 more vessels. Additional attacks on other targets led to the sinking or damaging of 12 more ships.
Despite the ongoing air attacks, the Imperial Japanese Navy still deemed it premature to fully activate Operation Sho-Go, believing the decisive battle would take place in or after late October. Meanwhile, the Imperial Japanese Army accelerated its preparations to defend the Philippines. The reserve 1st Division was ordered to move to the islands immediately, and plans were made to assign ten surface raiding regiments to the area. On September 26, as plans for air reinforcement to the Philippines were being approved, General Yamashita was confirmed as the new commander of the 14th Area Army. He arrived in the Philippines on October 6 and found the situation "unsatisfactory," with poor planning for the Leyte campaign and many of his staff unfamiliar with the conditions in the Philippines. Lt. Gen. Makino Shiro, now commanding the 16th Division, which was the major force on Leyte, had directed his efforts since April 1944 toward the construction of defensive positions on the island. The first line of defense, which was on the east coast in the Dulag area, was practically completed by the middle of October. The third defensive line was in the middle of Leyte Valley in the vicinity of Dagami. The second line of defense was between the two others, while the bulk of supplies was assembled in the central mountain range at Jaro. The distribution of the other troops at the time of the American landings was as follows: one battalion of the 9th Infantry Regiment in the Catmon Hill and Tanauan district, and the main strength of the 33d Infantry Regiment in the Palo and Tacloban area. The larger part of the 33d Infantry Regiment, which was less adequately trained than the other regiments, had arrived on Leyte in mid-September from Luzon. Its officers were unfamiliar with the terrain and did not fortify their positions.
However, the supply situation was favorable, with Manila serving as the main Japanese depot in the region. Following established plans, he instructed his subordinates that the Area Army would "seek decisive battle on Luzon" while in the central and southern Philippines, the focus would be to delay the enemy's advance and prevent them from securing naval and air bases. However, the September air strikes had led to a noticeable increase in guerrilla activity and civil disorder due to widespread destruction and panic. Small Japanese garrisons were attacked, pro-Japanese Filipinos molested and intimidated, and communications disrupted. In central Luzon there were indications that some guerrilla units were planning a move to the Lamon Bay area in order to be the first to cooperate with an American landing force, and on Negros and Panay guerrilla raids on Japanese airfields became boldly persistent. The Fourteenth Area Army feared that, as soon as enemy forces landed, the guerrillas would not only give them direct assistance as scouts and guides, but seriously hamper Japanese operations by attacking rear communication lines. Consequently, martial law was declared across the archipelago in anticipation of enemy landings.

Despite fierce and costly combat, American forces made significant advances in the Palaus, securing critical islands and establishing bases. The battle for Peleliu was marked by high casualties and intense fighting, with heavy losses on both sides. The successful capture of strategic locations like Ulithi Atoll and the subsequent strikes on Luzon further demonstrated Allied dominance and strategic planning in the Pacific Theater.

- 147 - Pacific War Podcast - Invasion of the Palau Islands 9 - September 18 - , 1944
10 sep· The Pacific War - week by week
Last time we spoke about the invasion of Morotai. After capturing the Marianas and Sansapor, the Allies planned to invade the Palaus and Halmahera. The Japanese stationed the 14th Division at Palau and the 32nd Division at Halmahera. General Ishii, with 11,000 troops, defended Halmahera's nine airfields, while Major Kawashima led 500 Formosans on Morotai. Meanwhile Colonel Nakagawa commanded the forces at Peleliu with extensive defenses, emphasizing attrition tactics. The Allies planned Operation Stalemate for Peleliu and Angaur, with General Geiger's corps set to land on September 15. Aerial reconnaissance and submarine missions informed their strategy. At Morotai, Operation Tradewind was executed by General Krueger’s 31st Division. Supported by air and naval bombardment, Allied troops swiftly secured key areas, encountering minimal Japanese resistance. These operations were part of broader Allied strategies involving coordinated air support and subsequent invasions in the region.
This episode is the Invasion of the Palau Islands

In last weeks episode we talked about the plans and preparations for the invasion of Palau. General Rupertus’ 1st Marine Division was assigned to assault Peleliu while General Mueller’s 81st Division would conduct a dual-pronged landing on Angaur. Meanwhile, Admiral Hoover’s land-based aircraft, General Kenney’s Allied Air Forces, and Admiral Mitscher’s carrier-based aircraft carried out an extensive neutralization program against Japanese airfields within range of Palau. When fighter planes of three fast carrier groups started sweeping over the Palaus on September 6, they found that the efforts of the Southwest Pacific's land-based bombers had succeeded in eliminating many ground targets. Nevertheless, fighters and bombers of the three groups started full-scale attacks on all the principal islands in the Palaus the next day. There was no air opposition, nor had there been any on the 6th. On the 8th, because observable targets were scarce, the weight of attack was reduced, and the carriers began preparing to move to Philippine waters. During their three days at the Palaus, the carrier-based planes flew about 1470 sorties, causing extensive damage to ammunition and supply dumps, barracks, warehouses, and a number of miscellaneous buildings. The groups claimed destruction of only four enemy aircraft, while losing eight of their own.
Admiral Fort’s slower-moving tractor groups, responsible for transporting both divisions to the islands, departed Guadalcanal with their respective screening forces on the morning of September 4. Four days later, fast transports and LSDs also set out to rendezvous with them in the early hours of September 15 after an uneventful voyage. In the interim, Admiral Davison’s carrier group launched a final sweep over the Palaus on September 10. The next day, Rear Admiral Jesse Oldendorf’s Western Fire Support Group and Rear Admiral Ralph Ofstie’s escort carriers arrived to begin the naval gunfire bombardment. Over the following three days, approximately 2,200 tons of naval projectiles were successfully fired on Peleliu. While Japanese positions pinpointed by the fire support ships were generally destroyed, many hidden by natural or man-made camouflage remained intact, as did those in areas not accessible to naval gunfire. Minesweepers cleared the 670 mines laid by the Japanese in the Peleliu-Angaur region and at least 240 more in the Kossol Passage. Nearly 175 mines were destroyed in the four days leading up to the landings, with the remaining mines marked at the cost of one minesweeper. Underwater demolition teams also began clearing obstacles from the landing beaches on September 12, providing the Japanese with clues about the Allied landing plans, leading them to hastily lay many land mines in the last few days.
By 05:15 on September 15, Fort’s transports had finally gathered off the Palaus and taken their assigned positions in the transport areas, ready for the landings to begin. Under clear skies, the small craft and amphibian vehicles of the assault waves formed up without difficulty and moved toward the reefs in front of Peleliu’s White and Orange Beaches. At 05:30, Oldendorf’s cruisers and destroyers started the pre-landing bombardment of the beaches, which was scheduled to cease at 07:50 to allow the carriers to conduct a final sweep. Ten minutes later, the first assault wave began advancing, supported by an LCI rocket barrage and aerial strafing attacks. However, the pre-landing bombardment had been inefficient, leaving many Japanese positions intact. Artillery and mortar fire quickly targeted the American amtracs, with several LVTs taking direct hits. Approximately 26 were destroyed during the landings, their burning hulks cluttering the beaches. Despite the smoke from Japanese fire and burning amtracs, the first wave reached the shore at 08:32. Colonel Chesty Puller’s 1st Marines landed on the left, Colonel Harold Harris’ 5th Marines in the center, and Colonel Herman Hanneken’s 7th Marines on the right. For those of you interested, a rather famous marine was with Harris’s 5th marines this day. Serving with K Company, 3rd battalion, 5th Marines was Eugene Sledge, the author of “with the Old Breed” probably the most famous Pacific War book of all time. If you are a fan of the HBO series: the Pacific, it was based loosely off this book amongst others. I think overall with the Old Breed does an outstanding job, particularly for when it was written, to showcase the brutal reality of the war in the Pacific. Eugene Sledge did not sugar coat things or gloss over terrible things he saw his fellow marines do, such as ripping out gold teeth from dead or even alive Japanese as well as taking human trophies like skulls or hands. Here is a passage:
We learned that our battalion would leave Peleliu as soon as a ship was available to transport us back to Pavuvu. By day we rested and swapped souvenirs, but we had to be on the alert at night for possible Japanese movement. To the south we could hear the constant rattle of machine guns and the thud of mortars and artillery as the 81st Infantry Division kept up the pressure around the Umurbrogol Pocket. “Have you gone Asiatic?” I gasped. “You know you can't keep that thing. Some officer'll put you on report sure as hell,” I remonstrated as I stared in horror at the shriveled human hand he had unwrapped. “Aw, Sledgehammer, nobody'll say anything. I've got to dry it in the sun a little more so it won't stink,” he said as he carefully laid it out on the rock in the hot sun. He explained that he thought a dried Japanese hand would be a more interesting souvenir than gold teeth. So when he found a corpse that was drying in the sun and not rotting, he simply took out his kabar and severed the hand from the corpse, and here it was, and what did I think? “I think you're nuts,” I said. “You know the CO will raise hell if he sees that.” “Hell no, Sledgehammer, nobody says anything about the guys collecting gold teeth, do they?” he argued. “Maybe so,” I said, “but it's just the idea of a human hand. Bury it.” He looked grimly at me, which was totally out of character for his amiable good nature. “How many Marines you reckon that hand pulled the trigger on?” he asked in an icy voice. I stared at the blackened, shriveled hand and wondered about what he said. I thought how I valued my own hands and what a miracle to do good or evil the human hand is. Although I didn't collect gold teeth, I had gotten used to the idea, but somehow a hand seemed to be going too far. The war had gotten to my friend; he had lost (briefly, I hoped) all his sensitivity. He was a twentiethcentury savage now, mild mannered though he still was. I shuddered to think that I might do the same thing if the war went on and on
Its a gripping read, highly recommend it, especially for quote en quote normie friends you might want to get into the Pacific War. Back to the story.Rupertus’ objectives for the first day were to push inland 300 yards to objective line O-1, then attack and capture O-2. Landing simultaneously with the fourth wave were the division's tanks (M-4 Shermans). Because of their excellent waterproofing for the operation, they successfully negotiated the reef, where the worst of the underwater obstacles had been removed by UDTs, and continued toward land in six parallel columns led by their respective LVT guides. The enemy fire, however, proved so intense that over half of 30 tanks organic to the division suffered from one to four hits during the 10 minutes necessary to cross the reef. In the 1st Marines' zone, for example, only one of the assigned tanks escaped being hit during the trip ashore. only three, however, were completely knocked out of action. "Thus within a half hour after the initial landing the infantry had full tank support--a record unsurpassed in any previous Marine landing in the Central Pacific, except for the Marshalls."
To make matters worse, no sooner had the lead elements of 3/1 landed and advanced less than 100 yards inland, than they found themselves confronted by a most formidable natural obstacle, a rugged coral ridge, some 30ft high. This had not shown up on any maps. Worse, the face of this ridge (christened "The Point" by the Marines) was honeycombed with caves and firing positions which the Japanese had blasted into the coral and had turned into excellent defensive positions which resisted all initial assaults. Even after tanks arrived to support the assault troops attempting to storm the northern portion of the ridge, they stumbled into a wide, deep anti-tank ditch, dominated by the ridge itself. Here they came under severe and accurate enfilading fire and were pinned down for hours.
The loss of much communication equipment further left Puller and Rupertus unaware of the situation on the left flank. A major effort was then launched to assault The Point from the rear. It became apparent to the Marines that The Point was unassailable from the front and so eventually units fought inland and assaulted The Point from the rear. These units, commanded by Capt George P. Hunt, fought their way along The Point for nearly two hours, during which time they succeeded in neutralizing all of the enemy infantry protecting the major defensive blockhouses and pill boxes. The principal defense installation was a reinforced concrete casement built into the coral, mounting a 25mm automatic cannon, which had been raking the assault beaches all morning. This blockhouse was taken from above by Lieutenant William L. Willis, who dropped a smoke grenade outside the blockhouse's embrasure, to cover the approach of his men, and Corporal Anderson who launched a rifle grenade through the firing aperture. This disabled the gun and ignited the ammunition inside the blockhouse. After a huge explosion, the fleeing Japanese defenders were mown down by waiting Marine riflemen.
Hunt's surviving 32 men remained isolated on The Point for the next 30 hours, constantly under attack from Japanese infiltrators. Meanwhile, Puller's 2nd Battalion pushed inland about 350 yards against moderate resistance. Despite this success, the 1st Marines' front was divided by two huge gaps. Puller's 1st Battalion was then committed to support the Marines on the left, successfully gaining a foothold on the southern area of The Point, but still unable to close the critical gaps. In the center, Harris' 1st Battalion advanced through coconut groves that provided ample cover, successfully reaching O-1 to link up with Puller's 2nd Battalion in front of the airfield by 09:30. On the right, however, Harris' 3rd Battalion and Hanneken's 3rd Battalion experienced a confused landing and made no progress, with only Harris' Company I reaching O-1 an hour after landing. At 10:30, the two battalions began pushing inland. Harris' Company K rapidly advanced deep into Peleliu's interior under the cover of fairly dense scrub, while the 7th Marines used a large anti-tank ditch to move forward in relative safety.
Again I thought it give more flavor if I took a passage from this moment when K Company advanced from Sledge:
We started to move inland. We had gone only a few yards when an enemy machine gun opened up from a scrub thicket to our right. Japanese 81mm and 90mm mortars then opened up on us. Everyone hit the deck; I dove into a shallow crater. The company was completely pinned down. All movement ceased. The shells fell faster, until I couldn't make out individual explosions, just continuous, crashing rumbles with an occasional ripping sound of shrapnel tearing low through the air overhead amid the roar. The air was murky with smoke and dust. Every muscle in my body was as tight as a piano wire. I shuddered and shook as though I were having a mild convulsion. Sweat flowed profusely. I prayed, clenched my teeth, squeezed my carbine stock, and cursed the Japanese. Our lieutenant, a Cape Gloucester veteran who was nearby, seemed to be in about the same shape. From the meager protection of my shallow crater I pitied him, or anyone, out on that flat coral
Hanneken soon faced strong opposition, leading him to pause his troops and request tank support in the afternoon. The requested tank support became somewhat confused by an unexpected coincidence: the flank battalions of the two assaulting regiments in the center and right were both the 3rd (3/5 and 3/7) with both containing Companies I, K, and L. The unfortunate tank commanders looking for 3/7 who had wandered into 3/5 area due to obstacles - in particular the large anti-tank ditch on Orange 3 - enquired of a body of troops they encountered "is this Company I, 3rd Battalion?" Hearing the right answer in the wrong place, they proceeded to operate with these troops, who were in fact Company I of 3/5 and not Company I of 3/7. Happily, this was one of those confusions of battle that helped more than it hindered. The confusion resulted in a gap between the two regiments as 3/7 paused to take stock of the situation, whereas 3/5 was actually pushing ahead. In an effort to re-establish contact with 3/5, Company L of the 7th Marines worked patrols further and further to the left until its foremost patrol emerged on the southern edge of the airfield. This was completely out of its regimental zone of action and several hundred yards to the rear of the units it was looking for.
By this time, Harris’ 2nd Battalion and Hanneken’s 1st Battalion had landed, with Harris’ battalion pushing vigorously northeast, while Hanneken’s battalion dealt with fierce Japanese resistance and a dense swamp to the south as they advanced toward O-1. Concerned about the slow progress on the right and the heavy casualties suffered by Hanneken’s forces, Rupertus decided to land the divisional reconnaissance company. However, the reserve 2nd Battalion, 7th Marines could not be disembarked until the next day.
One major Japanese counterattack occurred at around 16:50hrs on D-Day, consisting of a tank-infantry sortie in force across the northern portion of the airfield. This attack had been expected by the Marines, especially those of the 5th Marines facing open ground in front of the airfield, and accordingly the regimental commanders had brought up artillery and heavy machine guns as well as tanks to support that area. Increase in Japanese artillery and mortar fire in that area was the first indication that something was brewing. Soon after Japanese infantry was observed advancing across the airfield, not as a fanatical, drunken banzai charge but as a coolly disciplined advance of veteran infantrymen. A Navy air observer spotted Japanese tanks forming east of the ridges above the airfield with more infantry riding on them. These tanks moved forward, passing through the Japanese infantry advancing across the airfield and some 400 yards in front of the Marine lines. For a moment, but only for a moment, the Japanese counter-attack looked like a serious coordinated movement. Then the formation went to pieces. Inexplicably, the Japanese tank drivers opened their throttles wide and raced towards the Marine lines. Charging like the proverbial "Bats outa Hell," with the few infantry atop the tanks clinging on for dear life, they left their accompanying infantry foot support supp far behind. No positive account exists of what happened thereafter. The tanks involved in the charge numbered between 13 and 17 (insufficient pieces were left afterwards to give a definite count) and headed for the Marine lines, cutting diagonally across the front of 2/1, who subjected them to murderous flanking fire from all weapons, small arms, light and heavy machine guns, 37mm antitank guns and artillery. Two of the Japanese tanks veered off into the lines of 2/1, hurtling over a coral embankment and crashing into a swamp, the escaping crews were quickly disposed of by the Marines. Meantime, the remaining tanks came under heavy fire from the marines of 1/5, while the advancing Japanese infantry was subjected to fire and bombing from a passing Navy dive bomber. The tanks and their riding infantry were decimated as they passed right through the Marine lines which simply closed behind them.
At 17:00, a heavy mortar barrage struck Harris’ 3rd Battalion’s command post, causing the Marine companies to lose cohesion, though they eventually formed a defensive line along the airfield's edge. Under this barrage Eugene Sledge had this to say:
Under my first barrage since the fast-moving events of hitting the beach, I learned a new sensation: utter and absolute helplessness. The shelling lifted in about half an hour, although it seemed to me to have crashed on for hours. Time had no meaning to me. (This was particularly true when under a heavy shelling. I never could judge how long it lasted.) Orders then came to move out and I got up, covered by a layer of coral dust. I felt like jelly and couldn't believe any of us had survived that barrage.
By the end of the day, despite 210 men killed and 901 wounded, the progress of the beach expansion was disappointing. Again Eugene Sledge has a passage about getting through the first heat of combat on D-day at Peleliu:
We had to be alert constantly as we moved through the thick sniper-infested scrub. We received orders to halt in an open area as I came upon the first enemy dead I had ever seen, a dead Japanese medical corpsman and two riflemen. The medic apparently had been trying to administer aid when he was killed by one of our shells. His medical chest lay open beside him, and the various bandages and medicines were arranged neatly in compartments. The corpsman was on his back, his abdominal cavity laid bare. I stared in horror, shocked at the glistening viscera bespecked with fine coral dust. This can't have been a human being, I agonized. It looked more like the guts of one of the many rabbits or squirrels I had cleaned on hunting trips as a boy. I felt sick as I stared at the corpses. A sweating, dusty Company K veteran came up, looked first at the dead, and then at me. He slung his M1 rifle over his shoulder and leaned over the bodies. With the thumb and forefinger of one hand, he deftly plucked a pair of hornrimmed glasses from the face of the corpsman. This was done as casually as a guest plucking an hors d'oeuvre from a tray at a cocktail party. “Sledgehammer,” he said reproachfully, “don't stand there with your mouth open when there's all these good souvenirs laying around.” He held the glasses for me to see and added, “Look how thick that glass is. These sonsabitches must be half blind, but it don't seem to mess up their marksmanship any.” He then removed a Nambu pistol, slipped the belt off the corpse, and took the leather holster. He pulled off the steel helmet, reached inside, and took out a neatly folded Japanese flag covered with writing. The veteran pitched the helmet on the coral where it clanked and rattled, rolled the corpse over, and started pawing through the combat pack. The veteran's buddy came up and started stripping the other Japanese corpses. His take was a flag and other items. He then removed the bolts from the Japanese rifles and broke the stocks against the coral to render them useless to infiltrators. The first veteran said, “See you, Sledgehammer. Don't take any wooden nickels.” He and his buddy moved on. I hadn't budged an inch or said a word, just stood glued to the spot almost in a trance. The corpses were sprawled where the veterans had dragged them around to get into their packs and pockets. Would I become this casual and calloused about enemy dead? I wondered. Would the war dehumanize me so that I, too, could “field strip” enemy dead with such nonchalance? The time soon came when it didn't bother me a bit.
During the night, coordinated local counterattacks were repelled with relative ease, thanks to the support from naval gunfire and the artillery of the 11th Marines. However, the enemy’s resistance, which was not the frenzied banzai charges of previous encounters, began to suggest that the prolonged and organized opposition Rupertus had anticipated might indeed persist for a longer time. Meanwhile, with the 3rd Battalion, 15th Regiment cut off to the south, Nakagawa chose to withdraw most of his forces to the ridgelines and high ground north of the airfield, aiming to hold out as long as possible. The 1st Marine Division, enduring a night of harassment from Japanese mortar and artillery fire, faced heavy resistance from these ridgeline defenses on September 16. Despite this, after landing on Peleliu at 09:50, Rupertus made significant progress that day. His only adjustment was to order the reserve 2nd Battalion, 7th Marines to support Puller’s beleaguered 1st Marines to "maintain momentum." On the right flank, the 7th Marines pressed their hold on the southern part of the island despite heavy resistance and thick scrub, capturing all but two small promontories at the southern tip, where isolated defenders established their final positions. In the center, the 5th Marines cleared most of the remaining airfield area and set up defenses at night in a hangar and shop area on the field’s north side, while Puller’s 2nd Battalion secured the northwestern section of the airfield, including several headquarters buildings and barracks.
On the left flank, the 1st Marines struggled to advance against the determined and well-coordinated resistance from Nakagawa’s main defenses, which were concentrated around the Umurbrogol Mountains. Only after intense fighting and with the help of tanks did the Marines manage to capture a 500-yard stretch of the ridge. By nightfall, at the cost of approximately 30 additional men killed and 115 wounded, the division had established a perimeter extending over 3,000 yards from north to south, and about 2,000 yards deep at its farthest point. Over the course of two days, the Americans suffered nearly 1,500 casualties, with more than 1,000 from Puller’s 1st Marines alone. Despite these losses, the crucial objective—the Peleliu airfield area—had been secured. The Japanese defenses had been divided, with two small pockets in the south and the main stronghold in the central ridges. Feeling that operations were progressing well and possibly aiming to keep Peleliu an all-Marine endeavor, Rupertus decided not to request reinforcements from the 81st Division. Consequently, General Mueller’s forces were set to proceed with landings on Angaur the next day. Rear-Admiral William Blandy, commanding the Angaur Attack Group, reported that based on air and naval bombardments, hydrographic surveys, and UDT activities, a successful landing on Angaur appeared achievable. Admiral Fort and General Geiger thus approved the decision. Meanwhile, Major Goto Ushio had stationed his 1,400 men from the reinforced 1st Battalion, 59th Regiment in four defensive sectors with a small reserve in the center.
Expecting the Americans to land on the well-prepared Green Beaches to the southeast, he had fortified that area with his strongest coastal defenses. However, the Americans anticipated this and chose instead to land Colonel Benjamin Venable’s 322nd Regiment on Red Beach to the north and Colonel Robert Dark’s 321st Regiment on Blue Beach to the east. In the early hours of September 17, Blandy positioned his forces off Angaur and at 0530 the Angaur Fire Support Group started its bombardment, employing for the most part slow, methodical area fire rather than shooting at specific targets. The fire was characterized by the 81st Division as being "very satisfactory," and it accounted for about 40 percent of all naval shells thrown at Angaur from 12 through 17 September.
Due to a delay in the arrival of support aircraft, the shore bombardment continued past the scheduled time while General Mueller’s assault troops boarded the landing craft and amphibian vehicles meant to take them ashore. By 08:00, the LVT assault waves began positioning themselves at the line of departure, while the 323rd Regiment executed a feint at Green Beach to distract the Japanese from the actual landing sites. Ten minutes later, the assault waves moved toward the shore, supported by LCI rocket fire, ongoing bombardments, and strafing planes that had also arrived late. Despite encountering only light mortar and small-arms fire, Dark’s forces successfully landed on Blue Beach at 08:31, just one minute behind schedule. Venable’s first wave, however, was delayed and arrived at Red Beach six minutes late. Subsequent waves landed throughout the day amid light resistance but faced challenges such as traffic congestion and limited beach space. By 16:45, all tanks of the 710th Tank Battalion were ashore, and the 316th and 906th Field Artillery Battalions had successfully landed at Red Beach by nightfall. The artillery for Blue Beach was landed the following day. Additionally, Venable’s reserve 2nd Battalion landed by 11:30, and Dark’s reserve 1st Battalion arrived by 13:00.
After landing, Mueller’s green regiments began advancing inland about 300 yards to their first phase line, quickly becoming entangled in dense scrub forests teeming with Japanese machine guns and snipers. On Blue Beach, Dark’s troops proceeded cautiously at first, but by noon they had secured Rocky Point, Cape Ngariois, and established a beachhead approximately 1200 yards long and 350 yards deep. Meanwhile, Venable’s 1st Battalion moved swiftly north and inland through less dense undergrowth to secure its designated beachhead area. The 3rd Battalion bypassed some enemy bunkers set in jagged coral and proceeded south and west, successfully linking up with the 1st Battalion but falling short of reaching Cape Ngatpokul. With two secure beachheads and a 700-yard gap along the first phase line between regiments, Mueller ordered the 322nd Regiment to extend its right flank onto the second phase line about 400 yards inland and to continue pushing south with its left flank towards the sister regiment. By 14:30, the advances resumed, with Venable’s 1st Battalion pushing westward against light resistance into increasingly rough terrain along the coast and into a densely overgrown basin near the north end of Lake Aztec. Meanwhile, the 3rd Battalion engaged in patrol actions against isolated Japanese positions to secure the coastal area between the two landing beaches, though little progress was made. Dark’s forces also struggled, hindered by difficult terrain and mounting Japanese resistance.
Ignoring the gap between regiments, Mueller ordered Venable’s 3rd Battalion to advance to the second phase line. The battalion moved along railroad beds without encountering opposition, reaching the objective by nightfall. Simultaneously, Dark attempted to advance to the second phase line but made little progress before having to dig in. Goto, on the other hand, chose not to launch an immediate mass counterattack, believing that the 81st Division might land at other beaches. Instead, he deployed a company-strength mobile reserve for a counterattack, but this effort was disrupted by air and naval gunfire before it could commence. By late afternoon, realizing that the Americans had firmly established themselves ashore, Goto began moving his units and withdrew the southern defense force to the northwest hills for a final stand. To cover this movement, he ordered a night counterattack by two companies. At 05:50 on September 18, enemy infantry emerged from cover below Rocky Point and attacked Dark’s Company B, pushing the Americans back about 75 yards before being halted by a heavy concentration of fire. Meanwhile, small groups of Japanese forces repeatedly assaulted the defensive line south of Lake Aztec, near the boundary between the 1st and 3rd Battalions. Despite their efforts, they failed to exploit the gap between regiments and withdrew to the northwest hills shortly after dawn.

Thus the Marines were yet again storming new islands that would see them experience some of the worst horrors of WW2. A young enlisted man, Eugene Sledge would get his first experience of combat on Peleliu, and from there would begin to write a book that would captivate the minds of many in America, post WW2.

- 146 - Pacific War Podcast - Invasion of Morotai 2 - September 9 - , 1944
3 sep· The Pacific War - week by week
Last time we spoke about the end of Operation Dan. In Yunnan, by late July, General Wei's Y Force worked to eliminate Japanese garrisons at Tengchong, Mount Song, Pingda, and Longling. The 33rd Army prepared for Operation Dan, anticipating resistance from General Honda's garrisons until September. The fall of Myitkyina prompted Honda to expedite his plans. Reinforcements were expected in Mandalay by September. General Matsuyama's forces, cut off and surrounded, provided support only through radio messages. At Tengchong, Colonel Kurashige vowed to defend against relentless attacks. Chinese forces, after intense fighting and bombing raids, breached the city's defenses. Despite heavy casualties, the Japanese resisted fiercely. Major Kanemitsu’s garrison defended Moung Song with dwindling supplies. The Chinese forces employed siege tactics and underground mines to break Japanese strongholds. The Chinese launched coordinated attacks, capturing key positions and ultimately compelling Japanese retreats.

After the Marianas fell and Sansapor was captured, the Allies set their sights on their next objectives: the Palaus and Halmahera, slated for simultaneous invasion by mid-September. The Japanese had stationed the 14th Division at Palau and the 32nd Division at Halmahera as their primary defenses. The Halmahera-Morotai area had not assumed much importance to the Japanese until early 1944, when they began to develop Halmahera as a focal point for the defense of the southern approaches to the Philippines. In addition to the 32d Division, the Japanese had on Halmahera innumerable service organizations, and they completed or had under construction nine airfields on the island, most of them in northern Halmahera. On that island they concentrated nearly 30,000 men, including at least 11,000 combat troops.
On Halmahera, General Ishii commanded approximately 11,000 troops to safeguard nine airfields, despite having already lost most of their air power. Meanwhile, Morotai Island was defended by around 500 Formosans of the 2nd Raiding Unit, led by Major Kawashima Takenobu. General Ishii planned to counterattack from Halmahera if the Allies landed on Morotai, but soon realized Allied air and naval superiority would foil these efforts. Following their defeat in the Marianas, Tokyo reassigned the Bonin Area Group directly under its command and placed the Palau Area Group under the Southern Army, leaving General Mugikura’s 31st Army to defend Truk and other isolated outposts. General Inoue fortified Palau with elaborate defenses along the coast and inland, manned by 21,000 Imperial Japanese Army (IJA) troops, 7,000 Imperial Japanese Navy (IJN) personnel, and 10,000 laborers.
The IJN had by 1944 constructed numerous reinforced concrete blockhouses and bunkers plus dug an extensive tunnel system near the end of the northeast peninsula as well as taking full advantage of Peleliu's natural caves. This elaborate, multi-level tunnel system could shelter 1000 troops. These defenses, tunnels, the airfield, and the many support facilities were built by the 204th, 214th, and 235th Construction Battalions, mostly manned by Koreans and Okinawans. Detachments of the guard forces manned eight 120mm dual-purpose, and about three 200mm coast defense guns. There was no ammunition for the 200mm short guns nor did any ships report being fired on by coast defense guns. The 114th and 126th Anti-aircraft Units manned single and twin-barreled 25mm automatic guns (estimated at 30) and 13.2mm machine guns. A dozen 20mm cannons, removed from destroyed aircraft, were set up on makeshift mounts, mostly around the airfield. His strategy emphasized prolonged attrition over suicidal charges, aiming to exhaust the American forces. In preparation for the intense pre-landing bombardment, Inoue instructed his troops to utilize natural terrain features like coral caves and sinkholes, tactics that proved effective against the advancing Allies.Based in Koror, the Japanese commander stationed Colonel Nakagawa Kunio’s 2nd Regiment on Peleliu, the reinforced 1st Battalion of the 59th Regiment on Angaur, and deployed the 15th and 59th Regiments across Babelthuap and other islands. Major-General Yamaguchi Takeo’s 53rd Independent Mixed Brigade defended the central islands, complemented by 4,000 personnel from the Imperial Japanese Navy on Peleliu.
Prior to General Inoue’s arrival in the Palaus, the defense of the Palaus had been under the command of Vice-Admiral Ito Yoshioka. Upon his arrival on Koror, where he established his headquarters, Inoue appointed Colonel Nakagawa Kunio as Peleliu's new commander, with his 2nd Regiment (Reinforced). Nakagawa was a most able commander, possibly one of Japan's finest defensive tacticians, in the same league as General Kuribayashi on Iwo Jima. Nakagawa would make full use of all his defenses and troops on Peleliu, making the Americans pay dearly for every inch, as he had been ordered to do. Although a very capable commander, the appointment of an Army colonel over a Navy vice-admiral caused a great rift between the Army and Navy on Peleliu, which deteriorated into farce. To resolve matters and calm the Navy down somewhat, Inoue sent Major-General Murai Kenjiro from his headquarters on Koror Island to Peleliu to provide the Army with sufficient rank to satisfy the vice-admiral's honor, although the defense of Peleliu seems, to practical purposes, to have remained in the hands of Nakagawa. It appears that Murai, after inspecting Nakagawa's defensive works and battle plans for the defense of Peleliu, was content to let Nakagawa continue without interference from himself, lending only the weight of his rank to acquire the required cooperation of the Navy elements on Peleliu.
Nakagawa, divided the island into four defense sectors, each manned by an infantry battalion. His 1st Battalion, alongside the 14th Division Tank Unit and Engineer Company, served as a mobile reserve for counterattacks against potential landings. Meanwhile, Admirals Nimitz and Halsey had been planning Operation Stalemate, targeting Palau since May 29. Originally slated for September 8, General Geiger’s 3rd Amphibious Corps would assault Peleliu and Angaur, with General Hodge’s 24th Corps landing on Babelthuap.
Intelligence was gathered by aerial reconnaissance photographs. Also, in June 1944 the submarine USS Seawolf (SS-197) carried out photographic reconnaissance of the invasion landing beaches. A further reconnaissance was carried out by the submarine USS Burrfish (SS-312) on Peleliu and Yap beaches. An 11-man reconnaissance group of underwater demolition team (UDT) frogmen landed on the Peleliu beaches from the Burrfish for closer investigation relating to water depth, location of potholes and sandbars, and obstacles. With thousands of Japanese on the island they understandably did not reconnoiter inland, and the rugged terrain of the interior would come as an unpleasant surprise to the Marines. A similar operation was carried out on the Yap invasion beaches, but this time only two of a five-man reconnaissance team made it back to the pick-up point. After several unsuccessful attempts to locate their missing comrades the remaining two men returned to the Burrfish. After this incident, Admiral Nimitz banned any further missions of this type. Given delays in the Guam operation, Operation Stalemate was canceled on July 7, replaced by Stalemate II.
An unusual staff arrangement was established to plan Stalemate II. IIIAC was committed to take Guam under General Geiger. The IIIAC staff would thus be unable to plan the Palaus operation, which it was to execute. Consequently, Major General Julian Smith, designated to command the Expeditionary Troops, was tasked to plan the operation using his own small staff augmented by some IIIAC staff officers. This temporary planning staff was designated X-Ray Provisional Amphibious Corps. It would plan the operation and IIIAC would execute it – an awkward arrangement, but necessary in order to maintain the increasing tempo of operations. As Commander, Expeditionary Troops, Smith was also to be in control of all ground action in the western Carolines; a position roughly analogous to that of General Krueger of ALAMO Force in the Southwest Pacific. X-Ray was finally dissolved on August 15, 1944. This revised plan scheduled Geiger’s forces to land on Peleliu with the 1st Marine Division and on Angaur with the 81st Division on September 15, while the 77th Division remained in floating reserve and the 5th Marine Division in area reserve.
Then, on October 8th, the 24th Corps planned to launch an assault on the islands of Yap and Ulithi in the western Carolines. This was aimed at securing an additional airfield and fully neutralizing Truk and the remaining islands in the group. For this operation, Halsey divided his 3rd Fleet into two main echelons: his Task Force 30, which included covering forces such as Admiral Mitscher’s Fast Carrier Task Force (now Task Force 38), and Admiral Wilkinson’s Task Force 31, the Joint Expeditionary Force. At Peleliu, General Rupertus’ 1st Marine Division was to land with five battalions advancing over the White and Orange Beaches on the southwest coast. The 1st Marines were to land on the left, pushing up the western shore to clear Japanese forces from ridges overlooking the airfield; the 5th Marines would land in the center to secure the airfield; and the 7th Marines on the right to capture the southern end of the island. Meanwhile, at Angaur, Major-General Paul Mueller’s 81st Division planned a two-pronged amphibious assault. The 322nd Regiment was to land on Red Beach on the northeast coast, while the 321st Regiment would land on Blue Beach about 2000 yards to the southeast. Both forces would then push inland to secure a first phase line approximately 300 yards from the beaches, before continuing their advance west and south. The reserve 323rd Regiment was tasked with a feint landing at Beach Black on the northwest coast, with potential deployment to Ulithi if the Palau operations proved successful.
Meanwhile, General MacArthur aimed to establish an airbase in the Halmahera area, strategically positioned between the Vogelkop and Mindanao. This location would provide crucial flank protection against Japanese forces in the Dutch East Indies and support land-based operations for the upcoming invasion of Mindanao. Optimistically, in mid-June, MacArthur had tentatively scheduled the invasion of Mindanao for October 25. Nimitz, however, believed that MacArthur's hope of reaching Mindanao by October 25 was too optimistic. During conferences at Pearl Harbor in July, called at the suggestion of Nimitz to coordinate Southwest and Central Pacific plans for the Morotai, Palau, and Mindanao operations, Southwest Pacific planners learned that less amphibious craft and assault shipping could be made available to them than had previously been anticipated. Moreover, restudy of range and weather factors made it appear somewhat risky to depend upon the ability of Morotai-based aircraft to provide air support for Southwest Pacific forces on Mindanao after carriers had to leave the latter area and before airdromes could be developed there. To obtain adequate land-based air support for the Mindanao invasion force, MacArthur returned to discarded plans to seize air-base sites on the Talaud Islands, about equidistant from Morotai and Sarangani Bay, Mindanao, where the first landings in the Philippines were then scheduled to take place. The employment of amphibious means for the Talaud operation would delay preparations for Mindanao, as would the development of airdromes on the Talauds. Finally, to have the invasion of Mindanao take place much before the middle of November would involve a conflict in timing with anticipated employment of assault shipping and carrier support by Admiral Nimitz for the occupation of Yap and Ulithi in the western Carolines, an operation scheduled for the first week in October. MacArthur therefore revised his program to call for the invasion of Morotai on September 15, the Talauds on October 15, and Mindanao on November 15.
As Allied carriers were engaged in the Palau operation, MacArthur needed a target within range of fighters and medium bombers stationed at Sansapor. Thus, Morotai Island was chosen for Operation Tradewind due to its perceived light defenses and ample space for airfield and light naval base facilities. General Krueger selected the 31st Division and the 126th Regiment, totaling approximately 28,000 troops under the overall command of General Hall's 11th Corps, for this operation. Admiral Barbey's Task Force 77, comprising 12 destroyers, 2 APAs, 5 APDs, 1 LSD, 39 LCIs, 12 LSTs, and 12 LCTs, along with a covering force led by Admiral Berkey and an escort carrier force under Rear-Admiral Thomas Sprague, facilitated the amphibious movement. Additionally, Vice-Admiral John McCain's fast carrier group provided support. Anticipating minimal resistance, the landings were planned near prospective airfield sites on the Doroeba Plain in southwest Morotai. General Hall's strategy involved the 155th and 167th Regiments landing on Red Beach on the southwestern coast to swiftly capture the abandoned Pitoe Drome and secure the new Pitoe Airfield site. Meanwhile, the 124th Regiment landed at White Beach, about 1500 yards to the south, to secure the Gila Peninsula and the Wama Airfield site. The reserve 126th Regiment was scheduled to land the following day, with its 1st Battalion initially supporting the 124th Regiment's operations at the beachhead.
Both the Palau and Morotai operations were supported by a coordinated strategic air support program. Admiral Hoover's land-based aircraft were tasked with neutralizing Japanese airfields at various islands including Yap, Woleai, Truk, Ponape, Pagan, Bonin, and Marcus Islands. Concurrently, General Kenney's Allied Air Forces reinforced these efforts and targeted enemy air centers in Palau, Mindanao, western Dutch New Guinea, Halmahera, the Talaud Islands, the Moluccas, the Celebes, and the Arafura Sea islands. Additionally, Mitscher’s fast carriers embarked on an ambitious campaign, launching strikes from the Bonin and Volcano Islands to the Palaus and Mindanao between late August and the start of the invasions.
This strike had a twofold objective: the temporary neutralization of Japanese airfields on those island groups and, more important, the creation of a diversion on the north preceding stronger attacks against targets in the Philippines and western Carolines. Carrier action in the latter area was to begin on 6 September, with strikes on the Palaus, Yap, and Ulithi. The bulk of the carrier forces was to leave the western Carolines on the afternoon of the 8th to take up positions off Mindanao. Japanese airfields on Mindanao presented difficult targets because they were scattered over that large island, but it was believed that the cluster of airfields and associated installations in the Davao area would provide profitable targets for carrier-based aircraft attacks. The Davao and Sarangani Bay areas, as well as Japanese shipping routes from Davao to Zamboanga and thence north toward Manila, were also expected to provide profitable targets. Strikes against airdromes and shipping in the Mindanao area were to be carried out on 9 and 10 September, while on the 10th and 11th part of the carrier force was to hit the Palaus and Yap-Ulithi again.
Rear-Admiral Ralph Davison’s carrier-launched aircraft struck Chichi Jima and Iwo Jima from August 31 to September 2. The Fast Carrier Task Force continued with strikes on Yap and the Palaus from September 6 to 8, and on Mindanao from September 9 to 10. Enemy air resistance was surprisingly weak throughout these operations, prompting Halsey to redirect plans for a follow-up attack on Mindanao to the Central Philippines. While the Japanese forces in the Philippines hastened to complete preparations against anticipated Allied invasion, enemy carrier-borne aircraft served sudden warning on September 9 that the date of this invasion was fast drawing near. In the first large-scale air operation by the Allies against the Philippines, an estimated 400 carrier planes staged a devastating ten-hour offensive against southern Mindanao, concentrating their attacks on Davao, Sarangani, Cagayan and Digos. Since Japanese air patrols had failed to discover the enemy task force, the attacks achieved complete surprise and inflicted widespread and severe damage to ground installations, airfields, anchorages, and lines of communication. Reconnaissance units of the 1st Air Fleet immediately flew off search missions, which revealed that the attacks originated from three enemy naval task groups boldly maneuvering in the waters southeast of Mindanao. As per the Sho-Go directives, however, the 1st Air Fleet withheld retaliatory action pending further developments. Ground and naval units in the Davao area were nevertheless ordered on the alert to meet the possible contingency that an invasion attempt would follow the air strikes, and the Japanese armed forces throughout southern Mindanao became tense with expectancy. A feeling of nervousness gripped the weak local forces at Davao and rapidly spread to the large Japanese civilian colony. A wave of wild rumors swept the city. On September 10, a second series of heavy enemy raids aggravated this state of alarm. The city and harbor were reduced to a shambles and communications paralyzed. Panic and civil disorder broke out.
Less than 48 hours after the termination of the raids on Mindanao, the enemy struck again; this time in the central Philippines. On the morning of 12 September, a navy radar picket station on Suluan Island, in Leyte Gulf, broadcast over the general air-warning net that a vast formation of enemy carrier planes was heading westward toward the Visayas. Since the Suluan Island lookout was only about twenty minutes' flying time from Cebu, the air forces there could not be alerted quickly enough to put up an effective defense. By 0920 the enemy planes were already swarming over the Cebu airfields, where the main fighter strength of the First Air Fleet was based following its transfer from Davao. Although the attacks extended over the entire Visayan area and later took in Tawitawi, in the Sulu Archipelago, the Cebu fields appeared to be the principal objective. In the three days over which this air offensive continued, the First Air Fleet suffered damage to 50 Zero fighters on Cebu alone, while in other areas 30 additional aircraft of all types were rendered non-operational. Flight personnel suffered numerous casualties, and training was disrupted. Heavy damage was also sustained by Army air units. The 13th Air Brigade, made up of Type I fighters, was so hard hit that it had to be ordered back to Japan for regrouping, while the 45th Fighterbomber Regiment was reduced to half strength. In addition, 11 transports totalling 27,000 gross tons and 13 naval combat vessels were sent to the bottom of Cebu harbor.The unexpected weakness in enemy air defenses led Nimitz to reconsider bypassing Yap and Mindanao, instead focusing forces on an early invasion of Leyte. McCain’s group continued with attacks on Zamboanga, the Talauds, and Menado en route to Morotai. Meanwhile, between September 1 and 14, Kenney’s aircraft conducted heavy raids on Japanese air bases within range of Morotai, effectively isolating the island. Targeted locations included Halmahera, the northern Celebes, Ceram, western New Guinea, and Mindanao.
After rehearsals and preparations were completed, Barbey’s convoy departed Aitape on September 9. Two days later, they rendezvoused at Maffin Bay with the majority of General Persons’ 31st Division. The entire convoy departed the area on September 12, joined the next day by the covering force and escort carriers. The voyage proceeded smoothly, and Barbey successfully reached Morotai on the morning of September 15. Meanwhile, McCain’s carrier aircraft conducted a bombing and strafing mission over Japanese air bases in the Manado area, destroying 28 enemy aircraft. Kenney’s bombers also struck Japanese air installations on Batjan Island, while Berkey’s cruisers and destroyers shelled enemy positions along Galela Bay. Barbey’s surface warships conducted a bombardment of the landing area.
During the naval and air bombardment, assault ships moved into their assigned positions west of the landing beaches efficiently and without confusion. The initial waves formed quickly and landed the 155th and 167th Regiments on Red Beach at 08:30, followed by the 124th Regiment on White Beach one minute later. Encountering no opposition, the troops swiftly reorganized on shore and advanced toward their objectives inland. By 13:00, the 167th Regiment had secured Pitoe Drome, and by 15:00, Colonel Starr’s 1st Battalion had secured Gila Peninsula. Other units also advanced inland, establishing the 2000-yard beachhead line. Although there were some minor skirmishes, the Japanese could not mount significant resistance against the overwhelming Allied force and retreated into Morotai's rugged interior. The day's action resulted in seven wounded among the 124th Regiment and the loss of twelve Japanese soldiers, with one captured.
Beach conditions, however, proved unexpectedly poor, severely hindering the unloading efforts. Consequently, starting on September 16, all the LSTs, along with numerous LCTs and LCMs, had to be unloaded at Blue Beach, a favorable landing spot on Pitoe Bay's shores. Simultaneously, as the reserve 126th Regiment was disembarking, Persons resumed advancing inland against minimal opposition. Swiftly, they secured a perimeter around the Pitoe Drome area, spanning over 7000 yards wide and approximately 5000 yards deep. Following this, American patrols were dispatched to eliminate small Japanese groups, radar stations and observation posts were established on various offshore islands and Morotai's coastline, and efforts were made to expand the perimeter to the Sabatai River to accommodate additional bivouacs and supply installations.
Leaving Morotai behind, attention shifts to Burma to explore the aftermath of Operation U-Go. Following the decisive victories at Imphal-Kohima, General Slim opted to pursue retreating Japanese forces toward the Chindwin River, despite the need for rest among his weary British-Indian divisions. Consequently, the 23rd Division spearheaded the pursuit to Tamu, at the head of the Kabaw Valley, where Major-General Charles Fowkes' 11th East African Division took over in early August. Meanwhile, to the south, General Evans' 5th Division pressed toward Tiddim, encountering stubborn resistance from General Tanaka's 33rd Division. Slim's strategy aimed for both divisions to eliminate remaining Japanese forces west of the Chindwin and converge at Kalemyo. Subsequently, the Tiddim road would be abandoned as a supply route in favor of the Kabaw Valley and aerial resupply drops.
As a result, the 31st Division, now led by Lieutenant-General Kawata Tsuchitaro, successfully reached Sittaung. Their mission was to cover the withdrawal of other units in the region. Meanwhile, the 33rd Division faced challenges as it conducted delaying actions along the Tiddim road, with the added threat of East African forces potentially cutting off their withdrawal route towards Yazagyo. Japanese delaying tactics were always the same, and the means of dealing with them was also always the same. A crater would be found beyond which the lead infantry would come under fire and would have to be filled or covered using a Valentine bridgelayer, while air strikes would break up the blocking position to allow tanks from 3rd Carabiniers forward to support them.
To disrupt Tanaka’s communications south of the road, an ad hoc light unit, the Lushai Brigade, was deployed. By mid-August, General Mutaguchi ordered his forces to commence withdrawal towards the Zibyu Range. The 15th and 31st Divisions were directed to cross the Chindwin River by August 25, despite shortages of small boats. At the beginning of the crossing operation, a serious setback was experienced. It had been planned to bring small boats upstream to the crossing area with supplies for the Army and to utilize the same boats to evacuate casualties and heavy weapons south to Kalewa. Because of the enemy air activity over the Chindwin River, it was impossible to bring the boats to the crossing points. As a result, approximately 3000 sick and wounded were forced to cross the river and continue to the rear on foot with increasingly heavy death losses.
By August 31, they were expected to reach the eastern bank of the Chindwin, with the 15th Division consolidating along the Pinbon-Pinlebu line by the end of September and the 31st Division reaching Shwebo by mid-October. By the end of August, key command changes occurred following the setbacks of Operation U-Go. Lieutenant-General Katamura Shihachi replaced General Mutaguchi as commander of the 15th Army, while Lieutenant-General Kimura Heitaro took over from General Kawabe as commander of the Burma Area Army. Kimura Heitaro, noted for his strategic flexibility and acumen, subsequently directed the 33rd Army to secure a defensive line from Lashio to Mandalay, safeguarding the right flank of the 15th Army. The 15th Army, in turn, was tasked with holding the Irrawaddy River from Mandalay to Pakkoku, while the 28th Army was assigned to defend the Yenangyaung oilfields, the Arakan coast, and the Rangoon delta.
Meanwhile, on September 12, the 33rd Division crossed the Manipur River and proceeded with their retreat towards the Kabaw valley. They left the 215th Regiment to guard the rear at Tonzang, while units of the 5th Division infiltrated the area between Tonzang and Kalemyo to disrupt Tanaka's withdrawal and mount significant attacks against the 215th. By September 20, the Japanese forces were forced back to Tiddim, where the 214th Regiment covered the retreat of the rest of the division. Simultaneously, the 26th King’s African Rifles moved east from Tamu to Sittang, crossing the Chindwin River on September 8 to assess enemy strength across the river and prepare bridgeheads for a broader crossing. Encountering unexpectedly strong resistance, they were compelled to retreat back across the river. Under persistent pressure, the Japanese evacuated Tiddim on the night of October 6. Tanaka consolidated his division in the Kalemyo-Kalewa area by the end of October, while pursuing forces captured Fort White and Kennedy Peak. On October 10, the 4th King’s African Rifles launched an assault on Leik Ridge, suffering significant casualties but ultimately securing the main hill twelve days later. Meanwhile, after withdrawing from Mogaung, the 53rd Division regrouped at Mawhun by September 10, where they successfully defended against enemy units until the end of the month. They then retreated towards Pinwe and came under the command of the 15th Army on October 5.
Following the Quebec conference in September, a strategic overview of Burma emerged: the Combined Chiefs of Staff approved two plans. The first, codenamed Dracula, proposed an amphibious assault on Rangoon with a target date of March 15, 1945. The second plan, Capital, aimed at the conquest of north and central Burma, with General Slim suggesting an overland capture of Rangoon as part of the operation. Initially skeptical, the Americans reluctantly agreed to Dracula, contingent on ensuring that northern Burma received adequate resources. However, due to Allied setbacks at Arnhem and during the Battle of the Bulge, it became clear that reinforcements from the European theater could not be spared for the Rangoon offensive. Consequently, it was announced that the operation would need to be postponed until after the 1945 monsoon season.

After intense Allied operations in the Pacific, including the capture of the Marianas and Sansapor, attention turned to the Palaus and Halmahera. Japanese defenses were formidable, with significant troop concentrations and elaborate fortifications. Despite setbacks, Allied forces meticulously planned and executed operations, paving the way for further strategic advances in the region.

- 145 - Pacific War Podcast - Operation Dan 26 - August - September 2 , 1944
27 aug· The Pacific War - week by week
Last time we spoke about the battle of the Driniumor River. In July and August, American and Japanese forces clashed near Afua in New Guinea. Troop A of the 112th Cavalry engaged Japanese units, pushing them back temporarily. Troop C replaced Troop A but was soon isolated by Japanese attacks. The American TED Force, including the 124th and 169th Infantry, launched a counteroffensive, facing heavy resistance. Despite supply and terrain challenges, TED Force advanced, forcing the Japanese to gradually withdraw. By early August, the Japanese launched fierce and desperate attacks, but American defenses held firm. TED Force continued its advance, encountering further fierce Japanese resistance but successfully disrupting their supply lines. The Japanese, suffering heavy losses, were finally forced to begin a general retreat, as the American forces consolidated their positions by early August. It seemed Green Hell was still living up to its dreadful nickname.
This episode is Operation Dan

This week we are picking up with the action along the CBI theater. In Yunnan, by the end of July, General Wei's Y Force was still engaged in efforts to eliminate the resilient but small Japanese garrisons at Tengchong, Mount Song, Pingda, and Longling. Simultaneously, the 33rd Army was striving to accelerate preparations for Operation Dan, anticipating resistance from General Honda's main garrisons until September's end. Following the fall of Myitkyina in August, Honda recognized the need to expedite his offensive plans, despite delays in the deployment of the 2nd and 18th Divisions. Additional reinforcements from the 49th Division were expected in Mandalay by September, bolstering Honda's position. Meanwhile, General Matsuyama faced the challenge of isolated garrisons cut off from his 56th Division, surrounded by superior enemy forces. With his main forces focused on imminent offensive preparations, Matsuyama could only provide moral support through radio messages. Colonel Matsui's recent successes reduced Chinese activity on the Mangshi front, allowing for the rehabilitation of the 113th Regiment by August, despite occasional small-scale raids. At Tengchong, Colonel Kurashige resolved to defend the Walled City to the last man against relentless infantry assaults, air bombardments, and continuous enemy artillery preparations.
Compared with the defenses of Lameng, the positions at Tengchong were much less effective due to the factors of disadvantageous terrain and the lack of time to make defense preparations. Tengchong Castle covered an area slightly over a half-mile square; and was surrounded by a rampart 16 to 20 feet in height and over six feet thick at the top. Although the rampart had a stone facing and was backed with clay, it was not proof against an artillery bombardment and considerable work was required to strengthen it. Concrete or stone pillboxes were constructed adjacent to all gates and at the four corners. Shelters were built to protect guns and machine guns mounted on the rampart as well as for the troops and supplies inside the wall. Other entrenchments were prepared within the castle itself. While these measures greatly strengthened the defenses, the castle was still not proof against an intensive air or artillery bombardment. Recognizing the southeast as the primary avenue of approach, General Huo directed his forces to concentrate their main efforts in that direction.
On August 2, following another bombing raid by twelve B-25s that created a gap fifteen feet wide, the 36th and 116th Divisions initiated a new general assault. The Japanese quickly worked to repair the breach and fired machine guns to cover it. It was only after concentrating guns, rockets, and flamethrowers on the southwest pillbox, along with five waves of fighter cover fire, that the Chinese were able to position scaling ladders against the wall. Two companies then seized the top of the wall just east of the southern corner on August 3. Overnight, Kurashige led a successful counterattack that restored defenses along the rampart, except for one platoon that held its ground all night. This platoon's resilience allowed Chinese reinforcements to pass through the breach on August 4 and seize a pillbox inside the city. With the walls breached, the fall of Tengchong became inevitable, but the determined defenders continued to resist fiercely in the coming days, inflicting heavy casualties on the Chinese attackers. Meanwhile, Major Kanemitsu’s Lameng Garrison defended Moung Song fiercely. After the Hondo Position fell, the 308th Regiment resumed the advance on 3 August it had flamethrowers which it used with devastating effect to take the crest of Kung Lung-po. There the Chinese found several Japanese tankettes, which had been dug in for use as pillboxes. Despite repelling enemy attacks with great effort, the Japanese faced dangerously low ammunition supplies. As a result, Kanemitsu decided to raid the 8th Army's artillery positions and supply dumps to replenish his ammunition stocks. Twenty-nine men, selected from the artillery battalion, were divided into two teams for the purpose. One team was to raid the artillery positions on Shirakabe and Haraguchi Hills as well as to attack motor vehicles on the road between Lameng and Huitung Bridge. The second team was to operate in the area to the south and west of the Gake and Hondo Positions.
On the night of August 9, seven groups of Japanese volunteers launched a surprise attack, destroying several howitzers and seizing light weapons and ammunition. Despite Kanemitsu’s initial success and his troops' resilient defense against Chinese infantry assaults, General Song opted to revert to conventional siege tactics starting August 11. His divisions began digging tunnels beneath key Japanese strongholds in the Mount Song triangle, each tunnel stretching 22 feet to accommodate two powerful mines aimed at enemy pillboxes.One mine held 2,500 pounds of TNT, the other mine held 3,500 pounds of TNT. The mines detonated on August 20, causing significant damage that engineers exploited swiftly with flamethrowers, capturing Kanemitsu’s primary stronghold. In one pillbox forty-two Japanese were buried alive, of whom five were rescued. The prisoners stated that they had been asleep and had never suspected that they were being undermined. At 0920 the 3d Regiment against light opposition took the few strongpoints that remained on Sung Shan proper. In spite of particularly heavy pressure being exerted against the Sekiyama Position, the enemy had made little progress. However, on 19 August, following a heavy bombardment three tremendous blasts shook the Sekiyama Position. The Chinese, becoming discouraged with trying to storm the position, had tunneled under it, the defenders of the Sekiyama Position were virtually annihilated and the position fell to the enemy. On 23 August the Lameng Garrison regrouped to make final resist- ance in the Otobeyama, Nishiyama, Matsuyama, Yokomata and Urayama Po- sitions. The total number available for defense had been reduced to about 150 men, all of whom were wounded, some seriously. Even those who had lost an arm or a leg were propped up in positions where they could fire a rifle or sight a gun. The Lameng Garrison continued to resist in scattered pockets, launching futile counterattacks, Song recognized the battle's turning point.
During the latter part of July and early August, the Yunnan Force made new troop dispositions and moved in three divisions to attack the town. The main force of the Chinese 87th Division was on the east front, with an element along the Tien-Mien Road; the New 28th Division was between the two elements of the 87th; elements of the 1st Honor Division were on the north front with the New 39th Division on the south and west of Longling. At dawn on 14 August, preceded by an intense concentration of artillery fire and air bombardment, the Chinese forces launched a coordinated attack from all sides. Hill 6 bore the brunt of the enemy attack for eight hours but managed to hold, as did the defenders on the main line of resistance. After the attack had ceased, the Garrison spent the entire night rebuilding defenses, using rubble and half-burned mate- rial from the town. However, five days later, Chinese forces captured the eastern hills, weakening the entire Japanese defensive line. Consequently, by August 23, the eastern front collapsed, compelling the Japanese to retreat from their main defensive positions to reserve positions within the town.
Matsuyama was aware that under the current conditions, Longling would likely fall before September began. While the timely reinforcement of the 3rd Battalion, 148th Regiment would enable the garrison to hold out for a few more days, he understood the urgency of accelerating the Dan offensive to relieve Longling. Starting on 26 August, the 2nd Division began moving from Namhkam to Mangshih under cover of darkness, requiring three nights to complete the movement. Shortly thereafter, the headquarters of the 16th Regiment was called from Bhamo to Mangshih and Col. Hara Yoshimi, commanding officer of the 2nd Reconnaissance Regiment, succeeded Col. Sakai as commander of the Bhamo Garrison, which was placed under 18th Division control. On 30 August, the Division conducted a war game followed by a conference to brief subordinate commanders on the plans and missions of the Dan Operation.
With the recent arrival of the 4th and 146th Regiments, Matsuyama planned to send Matsui’s Task Force and the 146th Regiment northwestward to clear the western sector. Meanwhile, General Okazaki’s 2nd Division would attack northeastward to defeat the main enemy force in the eastern sector, thus fully relieving Longling. Subsequently, the 56th Division would advance towards Tengchong, while the 2nd Division moved towards Lameng, to relieve both isolated garrisons. However, before this offensive could begin, new developments emerged from Tengchong. Realizing that assaults on the ramparts were too costly, Huo ordered his Chinese troops to start tunneling under the walls. Additionally, air attacks increased in intensity, and on August 13, several large bombs struck the headquarters, killing Kurashige and leaving the garrison nearly leaderless. The following morning, after a heavy artillery bombardment of about 20,000 rounds, Huo launched his second general attack.
Despite the garrison's determined defense against Chinese attempts to breach or scale the ramparts, Huo reinforced his southern assault with the 198th Division, applying intense pressure. While defenders held against the combined attacks of more than two divisions, the 198th Division, which had made several ineffectual attacks in the northwestern sectors, was brought south to reinforce the units already there. Three divisions pitted against the badly damaged southern wall could not be held off and Chinese troops began infiltrating beyond the rampart. The garrison launched successive counterattacks and, while they were successful in driving the enemy out on the first two occasions, the third counterattack so exhausted the defenders that the enemy held the southwest corner of the compound. The Chinese were not, however, able to make any appreciable headway in breaching any other part of the castle's defenses.
Three days later, following another heavy air and artillery bombardment that succeeded in making seven breaches in the southern rampart, the Chinese resumed the offensive and managed to force the garrison to relinquish all but the southeast corner of the southern part of the castle compound. On August 22, a fourth attack was then launched; and, in spite of valiant efforts by the defenders, the west gate of the castle was finally taken by the 198th Division early in the morning of August 24. The following day, about 500 grenades and medical supplies were dropped by 12 Japanese fighters, which bolstered the garrison’s morale even though their fate was pretty much sealed already.
Simultaneously, Matsuyama initiated Operation Dan on August 26, with Matsui’s Task Force struggling for six days to secure control of Komatsu Hill before advancing towards Shuangpo on September 1. The Dan Offensive opened inauspiciously with an unsuccessful attack on Komatsu Hill, about three miles south of Lungling. Launched by the 1st Battalion, of the 113th Infantry (Takeda Battalion), on the morning of the 26th, the attack was thrown back and it was not until the following morning after the 3d Battalion, of the 113th (Murakami Battalion) had been thrown into the attack that the Takeda Battalion succeeded in seizing the western half of the hill. Upon achieving the objective, the Murakami Battalion was withdrawn and the Takeda Battalion was exposed to severe counterattacks which the enemy repeated for four days. The Takeda Battalion sustained extremely heavy losses, including the loss of three company commanders. The Inose Battalion attacked the hill from the northeast on 30 August and succeeded in making contact with the Takeda Battalion the following day but the northern part of the hill still remained in the possession of the enemy. Unable to hold up the advance any longer, the Inose Battalion was left at Komatsu Hill to clean out the remnants of the enemy and the main body of the Matsui Column advanced to Shuangpo on 1 September, fighting their way through enemy resistance.
The 146th Regiment successfully bypassed Chinese forces blocking the Tien-Mien Road, reaching the ridge west of Shuangpo. The 113th and 146th Regiments continued their northwestward advance, reaching the Longling River line by September 6, where they nearly wiped out the New 39th Division. Meanwhile, Okazaki assembled his 4th, 16th, and 29th Regiments at Shuangpo, preparing for an offensive. To the south, the 76th Division persisted in defending Komatsu Hill despite heavy casualties. Okazaki directed the 4th Regiment to attack the enemy’s northern positions on September 3, resulting in repeated assaults over the next three days. Despite suffering significant losses, the Japanese were compelled to halt their local offensive.
In the meantime, the 16th and 29th Regiments moved northeastward. The 29th Regiment successfully breached enemy positions and linked up with the besieged garrison by September 6. Despite this victory at Longling, subsequent events at Mount Song and Tengchong rendered Operation Dan futile. On August 29, following the fall of the Otobeyama Position, Kanemitsu realized that resistance could only last a few more days. On September 5 Major Kanemitsu sent to the commander of the 56th Division a final radio message: “All of my brave officers and men have determinedly defended our position for 120 days since May 10 with a sublime spirit of self-sacrifice and an attitude of absolute obedience. However, our ammunition has been entirely expended and practically every officer and man is wounded. The final moment has come. We will burn the colors and code books and make a suicide stand with what strength remains. I do not have the words to apologize for the fact that, because of my unresourceful command, we have been unable to hold out as long as expected. We are deeply moved by your long and special consideration of our situation. I respectfully ask that everything possible be done for the bereaved families of the officers and men of the Lameng Garrison. Our souls will continue to pray for the eternal prosperity of the Imperial Throne and the final victory of the Japanese Forces.”
Consequently, on September 5, he concentrated his remaining forces in the northernmost positions, which came under heavy enemy fire the next day. After Kanemitsu's death from a mortar shell, the Japanese burned their colors and euthanized their wounded. They launched a final suicide charge on September 7, resulting in the death of the remaining 50 survivors. Of the 1260 Japanese at Lameng Garrison, only 9 were captured and 10 believed to have escaped, with the rest perishing at the hands of Song's divisions, totaling approximately 41,675 troops. The significance of Mount Song lies in the four-month siege to clear the block from the Burma Road, during which the Chinese suffered 7675 casualties, including around 5000 from the 8th Army, leaving it with only two understrength regiments fit for further combat at Longling. Meanwhile, on August 31, Huo's fifth attack pressed with great enthusiasm, eventually succeeding in taking the southeast corner, which had withstood the onslaught of two divisions for over a month. The garrison was then pressed back to a line running from the east gate through the center of the palace grounds to the northwest corner of the castle grounds. The number of survivors had been reduced to approximately 350, virtually all of whom were wounded. Five days later, the Chinese attacked once again, successfully effecting a breakthrough of the defensive line which split the defending force into two groups. By September 9, the northwest corner had been completely overrun and only 70 men remained to hold the northeast corner. Realizing that the end was near, the Japanese burned their colors and on September 14 launched a last suicide charge in which the remainder of the garrison was finally cut down.
In a valiant defense, rivaling that of the Lameng Garrison, the 2025 men of the Tengchong Garrison held off the Chinese 20th Army, numbering an estimated 50,000 troops, for approximately 80 days. Despite this, the capture of Tengchong marked a significant victory for Y Force, as it opened a viable route to Myitkyina known as the "Tengchong cut-off". Moreover, the fall of Tengchong and Lameng allowed the Chinese to deploy more troops to counter the Dan offensive. In the early hours of September 7, the 113th and 146th Regiments crossed the Longling River and launched an assault on the 1st Honor Division, entrenched in strong defensive positions. Although General Matsui’s battalions were repelled by determined defenders, the 146th Regiment made notable progress on the left, gradually pushing the Chinese forces northward. By September 9, the western and northern sectors had been partially cleared, and the Longling Garrison was nearly completely relieved. Simultaneously, the 29th Regiment, supported by remnants of the 16th Regiment and the 2nd Field Artillery Regiment, advanced northeast towards the eastern hills, encountering difficulty in capturing them. By September 9, they had only secured one of the hills. With Honda growing impatient due to the slow progress of the 2nd Division. Okazaki directed increased attacks in the following days. An attack was launched on 11 September but did not succeed. Then an attack conducted on the 12th, y the 3d Battalion, 29th Infantry was successful in seizing the hill, however a counterattack by the enemy resulted in the annihilation of the Battalion and the retaking of the hill by the Chinese.
Furthermore, Okazaki also noted that the Chinese were still holding their ground to the south. Consequently, orders were issued for the 1st Battalion, 16th Regiment to address this lingering threat. However, the battalion exhibited such limited initiative that Colonel Tsuji Masanobu of the 33rd Army staff assumed direct command of the frontline units. With the addition of another battalion, this proactive commander led his troops in a series of vigorous assaults, culminating in the capture of the southern hill by September 15. Meanwhile, to the north, Matsuyama successfully relieved Longling, yet a new challenge emerged. The formidable 200th Division had arrived from Kunming and launched immediate attacks against the 113th and 146th Regiments by September 9. Fortunately, Matsuyama received reinforcements in the form of the 3rd Battalion, 148th Regiment and the reserve 168th Regiment, effectively clearing the northern sector by September 11. Positioned defensively, Matsuyama’s forces continued to fend off repeated counterattacks from the aggressive 200th Division, while the 168th Regiment moved westward to confront a significant element of the 36th Division advancing south from Tengchong. At this juncture, the Japanese had suffered approximately 1800 killed and 2500 wounded, while Honda estimated inflicting over 63,000 casualties since May. Despite the costly relief of Longling by mid-September, the 33rd Army had failed to reach the Nu Chiang River or rescue the Lameng or Tengchong Garrisons. Moreover, with Tengchong's fall, the entire 20th Army Group was mobilizing to reinforce Chinese forces engaged in the Longling campaign.
Realizing that Operation Dan faced inevitable failure, Honda opted to halt the offensive. Instead, he directed the 2nd Division to undertake a defensive stance south of Longling. Simultaneously, the 56th Division and the 168th Regiment disengaged from the enemy, moving southwards to relieve the Pingda Garrison. On September 16, the divisions rotated smoothly: the 56th Division gathered east of Mangshi, while Colonel Yoshida Shiro’s 168th Regiment initiated a covering attack to the east. This left the Longling Garrison vulnerable, prompting its commander to defy Honda’s orders and withdraw during the night. Lt. Col. Komuro's action came as a shock to Army and Division headquarters and, although he later committed suicide to atone for his act, the commander and the Garrison were considered to have disgraced themselves and the Japanese Army. Lt. Col. Nagai, a staff officer of the 56th Division, when questioned in 1959 made the following statement: "The Longling Garrison had twice before made great and courageous stands against tremendous odds. They were all exhausted by their efforts and had expected to be relieved. It is understandable that the Garrison should bitterly resent being placed in a position where they might possibly be surrounded in Longling a third time. The defense line of the 2nd Division was so drawn as to leave Longling projecting and constituting a primary target for enemy attacks. It should also be borne in mind that the Garrison was not an organic unit but was, instead, a composite group composed of various elements without the esprit de corps of a regular unit. Although Lt. Col. Komuro was a respected officer, his tendency toward a philosophical approach to life may have made it impossible for him to hold out against the unanimous discontent and resentment of his subordinates."
Fortunately, Matsui’s 3rd Battalion arrived in Longling two days later without encountering Chinese forces. Despite being outnumbered, the 2nd Division managed to maintain its extended front by destabilizing the enemy and conducting nightly raids. On September 17, Matsui launched a successful relief operation, driving the 9th Division from the Sahngzhai area. Concurrently, the 146th Regiment embarked on a forced march towards Pingda; by September 22, it breached the enemy lines, reaching the besieged city. Having been isolated for nearly six months, there were scenes of wild rejoicing as the besieged Garrison welcomed the Imaoka Column. Carrying about 150 casualties on stretchers the combined forces of the Imaoka Column and the Pingka Garrison broke through the enemy lines at night and, on the 24th, reached Liangtzuchai where they were covered by the Matsui Column. Both units withdrew to Mangshih and, when the Yoshida Force subsequently pulled back from Isao Hill, the Pingka relief operation was concluded. Following the conclusion of the Pingda relief operation, Honda began preparations for the impending enemy offensive.
Subsequently, the 56th Division was tasked again with defending Longling and Mangshi, while the 2nd Division relocated to Muse to prepare for a potential counterattack in the Shweli River valley. Meanwhile, the rested and reorganized 18th Division, now under Lieutenant-General Naka Eitaro, successfully concentrated at Namhkam by the end of September. The 33d Army expected that the main force would arrive prior to the end of the month, but the movement was executed very slowly and units were arriving in Namhkan throughout the month of September. Upon arrival of the Division at Namhkan, the units continued the work on fortification construction that had been started by the 2d Division. The main body of the Division moved via rail through Mandalay, while the 55th Infantry Regiment, with one artillery battalion and one engineer company advanced through Katha, Kunchaung and Sikaw on foot. The Division was gradually built up and, by the end of September, had achieved a strength of about 7,000 men. Since the replacements for the most part consisted of men recently discharged from hospitals, the complete recovery of the Division was understandably slow. The 18th Division finally managed to concentrate in Namhkam by 1 the early part of October. On 2 October, when Lt. Gen. Naka, who was replacing Lt. Gen. Tanaka, arrived at Namhkam, he found that the Division still had not fully recovered from the effects of the Hukawng Operation. However, abundant food supplies in the area, combined with excellent climate, enabled the division to make an unexpectedly rapid recovery during the month of October. By early November, the strength of the Division had been built up to about 9,000 men of whom about 3,000 were reinforcements from Japan. Some tanks and two 149-mm howitzers had been supplied and six mountain guns repaired. During this period of rehabilitation the Division engaged in the construction of defense positions on both sides of the Shweli River in the general area of Namhkam.
This period allowed the Japanese ample time to strengthen their defenses, as Y Force had suffered significant casualties. General Wei found it necessary to retrain and reorganize his depleted divisions before resuming the offensive in Yunnan. Because all of his immediate reserves had been drawn into the fight for Longling, and considering that the Chinese Government had ignored his earlier pleas, Wei Lihuang asked General Dorn, chief of staff of the American personnel working with Y-Force, to present his further requests for 20000 trained replacements (Wei had not received one since the offensive began); for two more divisions; for permission to use the 5th Army's tank battalion; and for Baoshan to be developed as a supply base. Dorn, however, was only partially successful in that the National Military Council renewed its promises to send replacements.
Shifting focus from Yunnan, we turn to the new operations of the 20th Bomber Command. Following the unsuccessful Yawata strike on August 20, Saunders continued planning for the return to Anshan, initially set for August 30 but postponed to September 8. On August 29, Major-General Curtis LeMay assumed command of the 20th Bomber Command. Despite the change in leadership, Saunders' plan remained unchanged: to deploy every serviceable B-29 aircraft. Saunders’ plan was to dispatch every B-29 fit to fly; and so, by September 8, 115 bombers had gathered in the forward area and 108 successfully got off the runways. Of these, 95 reached Anshan to find good weather, with 90 of them dropping 206.5 tons of bombs at the Showa works and 3 bombing other installations while another 5 hit the Xinxiang Railroad Yards and 3 others hit various targets of opportunity. Total losses for the mission were four: a crack-up near Dudhkundi on the way up; two forced landings in China, one destroyed on the ground by enemy planes and one partly salvaged; and a plane listed as missing. The crew of this last plane later walked out with the loss of only one man. The Americans in turn claimed 8 kills, 9 probables and 10 damaged.
The following day, a B-29 reconnaissance plane reported significant damage to the steelworks. Out of the sixteen coke oven batteries, three were estimated to be out of commission for a year, and another three for six months. Additional damage to related installations and the byproducts plant further compounded the impact. Overall, command intelligence officers calculated that the two attacks had reduced Showa's coking output by 35.2%, which in turn would decrease total Japanese rolled steel production by 9.3%. In response to the extensive damage, the Japanese launched their first counterattack against the 20th Bomber Command. Shortly after midnight, Japanese bombers came over Xinjin and attacked the American headquarters, storage areas, and the parked B-29s. Aided apparently by ground signals, the intruders made four runs, dropping fragmentation and high explosive bombs to inflict minor damage on one Superfortress and a C-46, and to wound two soldiers.
Meanwhile, LeMay, who had accompanied the mission to Anshan, was encouraged by the promising results. Despite this, he had been tasked with implementing significant changes to the command. He began revising tactics, tightening and expanding formations, and enhancing training for greater bombing precision—effects that would become evident in the following months. Specifically, LeMay intended to substitute for the current 4-plane diamond formation a 12-plane formation similar to one he had used with his heavies in the ETO. He proposed further to follow 8th Air Force practice by subordinating night missions, so far numbering four of the command’s eight strikes, to daylight precision attacks. This would not mean the abandonment of radar bombing, so vital in variable weather. LeMay’s doctrine called for “synchronous bombing” in which both the bombardier and radar operator followed the bomb run in, with visibility determining who would control the plane during the crucial seconds before release. Precision bombing required training more sustained than the sporadic sessions which the command’s crews had undergone, and fortunately new arrangements for nourishing strikes out of China would release B-29s and their crews from much of the Hump transport duty which had handicapped training. On September 5 LeMay had ordered each group to select 6 lead crews (later increased to 8) upon which other crews in a formation would drop. A week later a school was set up at Dudhkundi, occupied since early July by the 444th Group. Ground training and a simulated mission and critique on each of 10 successive days made the 11-day course at “Dudhkundi Tech” both strenuous and valuable. Meanwhile, the other crews of the 4 combat groups had been working with the 12-plane formation and had made some progress when training was interrupted for the ninth mission.
Most of September was spent initiating LeMay’s reforms, leaving time for only one major operation at the end of the month. Consequently, LeMay decided to finish off Anshan with another 100-plane strike. By September 26, he consequently had 117 B-29s forward, with 109 of them successfully getting airborne the following morning. Though take off had been improved since the last mission, bad weather and a cold front would see only 86 bombers reaching Anshan; 73 of them actually bombing the Showa works, all by radar. Subsequent photographic coverage, however, indicated absolutely no new darnage. In addition, two B-29s bombed Dairen, four Xinxiang, and nine bombed various targets of opportunity. Japanese opposition was likewise ineffective, with the Americans suffering no losses. but during the night, enemy bombers managed to sweep into the Chengdu area to drop three strings of bombs and damage five bombers, two of them seriously. The Chinese warning net had tracked the Japanese planes in from Hankow airfields and the 317th Fighter Control Squadron at Chengtu had ample time to alert command personnel. But the one P-47 up could not make contact. The 312th Wing had suffered with other China-based units from lack of supplies, and in the interest of economy of fuel one of its P-47 groups had been exchanged for the 311th Fighter Group, equipped with P-51B’s. Chennault, reluctant to tie down two full groups for the static defense of Chengtu, had disposed part of the wing forward where the planes could take a more active part in the war, and events were to prove that this policy constituted no serious danger to the B-29 fields.

By mid-September, intense battles in the CBI theater saw the Japanese forces grappling with diminishing supplies and overwhelming Chinese offensives. Despite heroic defenses at Tengchong and Lameng, Japanese positions fell after heavy casualties and strategic missteps. General Matsuyama's relief efforts at Longling achieved temporary success, yet the broader objectives of Operation Dan were unmet, marking a turning point in the campaign.

- 144 - Pacific War Podcast - Battle of the Driniumor River 19 - August - 26, 1944
20 aug· The Pacific War - week by week
Last time we spoke about the fall of Myitkyina. By late July 1944, the Japanese at Myitkyina in northern Burma were facing severe challenges. Despite holding out through a long siege, they were cut off from supplies and suffering heavy casualties. A leadership conflict between Colonel Maruyama and General Minakami further complicated things. Maruyama defended the city intensely, while Minakami aimed to deny Allied access to strategic roads. With depleted forces, including wounded troops trying to escape via the Irrawaddy River, the Japanese defense weakened. Allied forces, reinforced and ready, made significant gains, shrinking Japanese-held areas. On August 1, Minakami agreed to withdraw, and the remaining Japanese began escaping across the river. The Allies launched a final attack, securing Myitkyina on August 3. The 10 week siege resulted in substantial casualties on both sides. This victory allowed the Allies to improve logistical routes and marked a critical point in the Burma campaign.

Last time we were seeing action kick up at the Driniumor River. While the Japanese offensive had initially been successful, General Hall's forces managed to halt the enemy advance and reform their river line by July 15, despite a 1500-yard gap in the center. The Japanese were aware of this weakness in the American lines and exploited it, especially during the night. However, Colonel Starr's 3rd Battalion patrolled this area and occasionally engaged the enemy, killing 135 Japanese on the night of July 14. Despite this, General Cunningham claimed that his South Force had extended its lines nearly 1000 yards beyond its assigned sector without encountering any elements of the 124th Regiment. Consequently, on July 15, Starr concluded that his regiment had not advanced as far south as previously reported and ordered his units to adjust their lines southward and extend their defenses up the Driniumor towards Cunningham's Troop E. The following morning, Starr's 3rd Battalion began moving south to close the gap. As they reached the area by nightfall, Troop E was attacked by two companies of the 1st Battalion, 239th Regiment. While the cavalrymen sought cover, Starr's 3rd Battalion was also attacked by Colonel Nara's 3rd Battalion, which had turned south after its defeat at the Paup villages. This split the American forces in two, with Companies L and M pushing south through increasing opposition to reach South Force lines, while Companies I and K dug in for the night in their current positions. Despite the intense fighting, several Japanese were killed, and the gap was reduced to 500 yards.
In the course of the day's fighting the Coastal Attack Force had lost all its artillery and had suffered heavy casualties. Additional losses were sustained on succeeding days, but Major Hoshino and his men were not completely removed as an irritant until the night of 16-17 July. During that night remnants of the Coastal Attack Force, about thirty-five men strong, attacked North Force and 124th Infantry command post installations at Anamo. At 23:00 the group charged out of the jungle southwest of the Anamo perimeter. Repulsed by machine gun fire, the enemy temporarily disappeared, only to reappear at 03:00 on 17 July moving west against Anamo along the beach. Machine gun fire from the American positions broke up this second attack, but about ten minutes later the Japanese tried again, this time moving on Anamo from the north by wading in from the sea. Once ashore, Major Hoshino's men broke up into small groups, attempting to destroy mechanized equipment, automatic weapons positions, and communications installations. The Coastal Attack Force remnants had apparently scouted well, for they were reported to have moved purposefully toward the most important installations and they easily found their way about in terrain they had vacated only four days previously. Whatever Major Hoshino's plans were, they were not realized. About forty of his men were killed and the rest dispersed.
Behind them, Hall dispatched Colonel Howe’s 1st and 2nd Battalions to clear the remaining enemy units west of the Driniumor River. Over two days of complex and sometimes uncoordinated company actions, the Americans successfully overran Nara’s stragglers in the area. Further south, as Japanese troops were seen crossing the Driniumor at a fording point about 2,500 yards south of Afua, Cunningham sent Troop A south to high ground behind the Driniumor to halt the Japanese movements westwards. There, the 78th and 80th Regiments, under Major-General Miyake Sadahiko, were assembling for a renewed offensive. Adachi’s new plan involved Miyake striking Afua from the south while the 239th Regiment prepared to move against the Kawanaka Shima area. Additionally, the retreating 237th Regiment and the reserve 66th Regiment were ordered south to join future attacks by the 20th Division, though they wouldn’t arrive until July 25. As the Miyake Force maneuvered into position to the right and rear of Cunningham’s 1st Squadron, Starr struggled to close the gap in the center, which was eventually sealed on the morning of July 18. That night, Miyake launched an attack with two battalions on the 1st Squadron's command post and the adjacent perimeter held by Troop A, successfully pushing them 250 yards to the northeast.
Early in the afternoon of 19 July fresh Japanese units began to surround the Troop A position, moving in from the north, northwest, west, and southwest. The 1st Squadron commander called for artillery fire to break up this enemy maneuver. Upon cessation of the fire, Troop A attacked to the south and west for a second time. Driving at least a company of Japanese before it, the troop pushed 600 yards southwest of its original positions astride the Afua-Palauru trail and temporarily disrupted enemy plans to seize the position. About 140 Japanese had been killed during the two days' operation around Troop A. South Force, at the same time, lost 8 men killed and 29 wounded, all from the 1st Squadron, 112th Cavalry. There were strong indications that more attacks might occur in the 1st Squadron area, but Troop A was not destined to take part in any of these actions. It was replaced on the 21st by Troop C.
Following this victory on July 21, Troop C relieved the battered Troop A, Howe’s battalions successfully set up a patrol base on the East Branch of Koronal Creek, and Starr’s 2nd Battalion moved to Palauru to provide additional outer security southwest of the airfield. On July 19, the first elements of General Wing’s 43rd Division began landing at Aitape, with the 2nd Battalion, 169th Regiment subsequently taking over about 1,000 yards of the river line on the right of the 124th Regiment by July 22. Meanwhile, Adachi ordered the still-reorganizing Miyake Force to attack Afua from the north and west while General Nakai’s 79th Regiment crossed the Driniumor and attacked from the south. On the evening of July 21, Miyake launched his attack on Troop C’s position, successfully cutting it off from the rest of South Force. While the cavalrymen resisted heavy Japanese attacks, Miyake’s units also repelled Cunningham’s attempts to relieve the beleaguered troop over the next few days. Not knowing what other plans the Japanese might have in mind, General Cunningham was unwilling to pull any more troops away from the river defenses. Moreover, he now considered the position of his right flank untenable. He therefore withdrew Troop B north of Afua about 1,000 yards and used the unit to form a new defense line which ran westward about 500 yards from Troop A's right flank, anchored on the Driniumor. South Force's right flank was now refused and additional protection had been secured for medical, supply, and command post installations at the dropping ground banana patch. Troop C was left isolated behind Japanese lines, and Afua was again released to the enemy.
It was not until the night of 21-22 July that the Japanese forward units were able to organize for any sort of attack. During that night, elements of the 124th Infantry received considerable mortar, machine gun, and rifle fire from east of the Driniumor. This fire increased the next morning, and about noon the 3d Battalion, 124th Infantry, was attacked from the west by elements of the 237th Infantry. The first Japanese attack was ". . . finally broken up by a bayonet charge . . ." conducted by elements of the 3d Battalion, 124th Infantry, but other attacks followed as troops of the 1st Battalion, 239th Infantry, tried to move across the Driniumor from the east, striking both the 124th Infantry's unit and part of the 2d Battalion, 169th Infantry. Before dark on the 22d, the 3d Battalion, 124th Infantry, counted 155 new Japanese dead in its area. That unit and the 2d Battalion, 169th Infantry, reported their own losses as five killed and twenty-five wounded.
The 1st Battalion, 239th Regiment made further unsuccessful attempts to reopen the river crossing. By July 25, Adachi decided to send the 41st Division south to assist in the southern effort. After the fall of Afua, Hall ordered Howe’s battalions to leave their East Branch base and reinforce Cunningham’s South Force, arriving at the new line by July 23. With these reinforcements, Cunningham decided early in the afternoon to send Troops A and B to attack west toward Troop C while Howe’s 2nd Battalion pushed southeast toward the isolated troop. Despite being uncoordinated, the infantry successfully moved into Troop C's perimeter from the northwest and helped repel a heavy Japanese attack from the southwest, while the cavalry troops reoccupied Afua and established new defensive positions. However, American attempts to break out on July 24 were unsuccessful due to the Japanese defending all tracks, trails, and ridgelines in the heavily jungled ground northeast of the perimeter. On July 25, Howe’s Companies E and B unexpectedly established contact about 500 yards north of the besieged forces against light resistance, allowing the battered Troop C to withdraw. With Troop C relieved, Howe’s units continued to attack south and west towards the Afua-Palauru trail, successfully pushing the Japanese into the Torricelli Mountains.
Many Japanese troops remained positioned in a triangular area bounded by the dropping ground, Afua, and Company G's ridgeline position, where they continued to harass Cunningham’s forces. Rifle fire, intensifying as darkness approached, harassed the rear and right flank of the two battalions, and the Japanese began intermittently to drop light artillery or mortar shells into the banana patch area, where the command posts of South Force, the 112th Cavalry, and the 127th Infantry were now located. Finally, Japanese patrols, coming in from the west, had scouted the banana patch area during the day, action which seemed to presage an enemy attack during the night. To get out of range of the enemy fire and danger of enemy attack, General Cunningham moved the command post installations 500 yards to the north before dark. Additionally, 127th Infantry patrols had found a Japanese map which indicated that the 66th Infantry, 51st Division, was concentrating in the Kwamagnirk area. Indeed, the 66th Infantry, which, with attached units, was at least 1,000 men strong, had crossed the Driniumor on or about 24 July. Bypassing the right flank of South Force, the regiment had moved into the heavily jungled high ground west of the banana patch and dropping ground. In addition, the remnants of the 237th Infantry, probably about 300 men strong, had finally arrived in the Afua area on 25 July and had passed to the control of the Miyake Force. Rear elements of the 20th Division, including additional men from the 26th Field Artillery and engineer units, had also crossed the Driniumor south of Afua. The number of Japanese troops in the South Force area by nightfall on the 26th of July was at least 2,500 and may have been over 3,000.
On July 27, the battalion launched a successful southward attack, but ongoing Japanese movements to the west eventually necessitated an American withdrawal, despite other units under Cunningham managing to repel enemy advances. The following day, Cunningham consolidated his positions to bolster defenses in anticipation of potential large-scale Japanese assaults. However, on July 29, efforts by the 1st Squadron and the 2nd Battalion to attack south and west into the Triangle were thwarted by determined Japanese defenders led by Adachi. As a result, only localized patrol actions were conducted on July 30 and 31, as Cunningham devised plans for another offensive into the Triangle.
Major combat activity revolved around the withdrawal of Company G, 127th Infantry, from its exposed outpost west of Afua. On the afternoon of the 29th the unit had been driven more than 400 yards east of its original position by Japanese attacks and had established new defenses on high ground about 300 yards west of Afua. On the 30th the company was surrounded and spent all day fighting off a series of small-scale attacks. The next morning it fought its way north to the dropping ground, where it arrived about 1330. Thence, it moved on to the Driniumor and joined the rest of the 2d Battalion, 127th Infantry, which had switched positions with the 3d Battalion. During the period from 13 to 31 July, South Force had suffered almost 1,000 casualties, of which 260 had been incurred by the 112th Cavalry. For the understrength cavalry regiment, this was a casualty rate of over 17 percent. The 2d Battalion, 127th Infantry, had also lost heavily and was in need of rest, reorganization, and re-equipment--needs which had prompted General Cunningham to change the places of the 2d and 3d Battalions, 127th Infantry. South Force casualties were as follows: 106 killed, 386 wounded, 18 missing, and 426 evacuated as a result of disease and sickness. South Force estimated that it had killed over 700 Japanese. By the end of July, with the arrival of most of the 41st Division, Adachi believed he had amassed enough reinforcements near Afua to launch a final offensive.
The 238th Regiment, the 41st Mountain Artillery, and the 8th Independent Engineers were across the river in time by the 30th but the 2nd and 3rd Battalions, 239th Regiment, had missed the crossing point on the Driniumor and were lost. Fortunately for the 18th Army, the South Force withdrawals on July 29 and 30 gave the 20th and 41st Divisions time to complete their organization. New orders were issued for the attack to start on August 1, with the 20th Division on the west and the 41st Division on the east. The strength that the 20th Division could muster for the attack was a little over 2000 men. Most of these troops had been without food for some time. They were suffering from starvation, malaria, and skin diseases, and morale was cracking. They were short of both ammunition and weapons. The 41st Division and its attached units, totaling nearly 1750 men by the morning of August 1, were in equally bad shape. Nevertheless, General Adachi was determined to make one last attack with the nearly 4000 troops now available to him in the Afua area.
Despite sensing minimal Japanese resistance to the north, Hall was eager to mount a robust counteroffensive against the 18th Army. The 2d Battalion, 124th Infantry, which had been patrolling in the Palauru-Chinapelli area, was relieved from that duty by the 1st Battalion, 169th Infantry, and on the 30th joined its regiment at the Driniumor. The 2d Battalion, 169th Infantry, was already at the river. Tactical control of the counteroffensive was vested in Col. Edward M. Starr, commanding officer of the 124th Infantry, whose counterattack organization was to be known as TED Force. The 1st Battalion, 124th Infantry, was commanded by Maj. Ralph D. Burns; the 2d Battalion by Lt. Col. Robert M. Fowler; the 3d Battalion by Lt. Col. George D. Williams; and the 2d Battalion, 169th Infantry, by Maj. William F. Lewis. To avoid confusion, the four battalions were referred to by the last names of their commanders rather than by their number designations. Fowler's battalion, attacking along the coast, was to be supplied by ration trains moving along the coastal trail from Anamo. The rest of TED Force, pushing through trackless, dense jungle, was to be supplied by airdrop. The 149th Field Artillery Battalion, augmented by the Cannon Company, 124th Infantry, was responsible for artillery support, but when necessary the 129th Field Artillery was to add its fire to that of the 149th. All the artillery units were emplaced on the beach west of the Driniumor's mouth. The positions which the 124th Infantry and the 2d Battalion, 169th Infantry, left vacant on the Driniumor were to be occupied by the 2d and 3d Battalions, 128th Infantry. Colonel Starr had succeeded General Stark as commander of North Force on 18 July when the arrival of elements of the 43d Division at Aitape made it necessary for General Stark, the assistant division commander, to move back to BLUE Beach for administrative duties. General Stark apparently also reassumed command of the Western Sector, in place of General Hutchinson, Assistant Division Commander, 31st Division, who had rejoined his division when it, less the 124th Infantry, moved to a new operational area in western New Guinea. When TED Force was organized, North Force as such apparently ceased to exist, and the 128th Infantry took over the defensive functions previously assigned to North Force on the Driniumor. The name TED Force originated from the diminutive for Colonel Starr's first name. There were always so many units from different divisions and regiments operating along the Driniumor that the task force usually found it more convenient to use names rather than numbers for unit designations. The names, usually derived from the commanding officers, served not only to lessen confusion but also did double duty as code names.
The attack was to be carried out with three battalions abreast along a front of 3,000 yards, and the fourth in reserve and in position to protect the right flank of the advancing force. The four battalions were to move east to the line of Niumen Creek, destroying all enemy found between that stream and the Driniumor within the 3,000-yard-wide zone of responsibility. Upon their arrival on the Niumen the battalions were to reorganize and prepare for further advances either east or south upon orders from General Hall. All three battalions of the 124th Infantry began crossing the Driniumor on schedule at 0800, 31 July, moving into terrain concerning which only incomplete and sometimes inaccurate information was available. The 1st Battalion faced delays from enemy delaying actions but eventually reached the creek by August 1, while the remaining battalions advanced inland, also reaching Niumen successfully.
The 1st Battalion’s advance company had been held up about 800 yards east of the Driniumor by elements of the 1st Battalion, 239th Infantry, which had been left along the river when the rest of that Japanese regiment had moved south to Afua on 26 July. Burns' men continued to encounter strong opposition from 239th Infantry elements throughout the day and did not break off contact until 1730, when the battalion bivouacked for the night still 800 yards west of Niumen Creek. Company A had become separated during the day and remained some 550 yards northwest of the main body for the night. Both sections of the battalion were out of touch with the rest of TED Force. The 3d Battalion, 124th Infantry (Williams), crossed the Driniumor at a point about 3,000 yards inland and reached the Niumen about 1400, having encountered only scattered rifle fire. Lewis' 2d Battalion, 169th Infantry, which followed Williams' command, made no contact with the enemy and bivouacked for the night about 500 yards west of Williams. All battalions spent the next day, 1 August, consolidating and patrolling along Neumen Creek, and Burns' unit moved up into line with the others.
Meanwhile, Cunningham planned his own offensive aimed at dismantling the Triangle position following a reconnaissance mission along the Afua-Palauru trail. However, preliminary actions were disrupted when two companies launched a surprise attack from the southwest against Troop C's lines at 06:20 on August 1. General Cunningham immediately canceled the planned reconnaissance in force into the triangle area and turned his attention to this new threat. The first Japanese assault units were quickly reinforced, and the enemy moved forward against Troop C in massed waves along a narrow front. A bloody battle ensued as the enemy, apparently determined to commit suicide, continued his mass attacks. South Force called for artillery support, which was quickly forthcoming and which greatly helped Troop C to throw back the enemy assaults. By 0800 the Japanese had withdrawn and the battle area had become strangely quiet. Patrols were sent out from the cavalry perimeter to reconnoiter. These parties counted 180 dead Japanese in front of Troop C's lines, and it was considered probable that the enemy had carried off many more dead and wounded. Troop C, on the other hand, had lost but 5 men killed and 6 wounded. Examination of the enemy dead disclosed that elements of both the 80th and 238th Infantry Regiments had participated in the attacks. Thirty minutes later, Cunningham proceeded with his reconnaissance mission, encountering minimal resistance before returning in the afternoon. Despite capturing documents indicating an impending major assault, Cunningham deployed the 2nd Squadron as a mobile reserve at his command post.
Although the movement of the 2d Squadron had apparently been well advised, the Japanese did not attack the command post area. Instead, at 1900, elements of the 41st Division struck the 1st Battalion, 127th Infantry, at its lines south of the dropping ground. This attack was preceded by fire from a 70-mm. or 75-mm. artillery piece which the Japanese had managed to sneak into the area within 150 yards of Company B, 127th Infantry. Following a few rounds from this weapon, Japanese infantry charged forward in four separate waves, employing perhaps 300 men on a very narrow front. Few of the enemy got near Company B's positions, for the attack was thrown back with artillery, mortar, and machine gun fire, which caused heavy losses among the enemy forces. By 2030, action in the dropping ground area stopped for the night. During the early hours of the next morning, 3 August, the 1st Battalion, 127th Infantry, again heard enemy activity to its front, and about 0730 a small Japanese party struck between Companies A and C. This attack was quickly repulsed, principally by mortar fire from 1st Battalion units. By noon all activity in the 1st Battalion area had ceased, and the Japanese had withdrawn to the southwest.
Concurrently, Cunningham’s 1st Squadron faced attacks from Nakai’s 20th Division, but their suicidal charges were also turned back by resilient defenders. The 1st Squadron, 112th Cavalry, on the left rear of the 1st Battalion, was attacked by another group of Japanese at 1945. This action was probably meant to have been coordinated with the attack on Company B, but, if this were the enemy's intention, something had gone wrong. Apparently there had also been some mix-up in unit dispositions, for both enemy efforts had entailed the use of elements of the 78th, 80th, and 238th Infantry Regiments. After the day's action was finished, the combined effective strength of the first two units was probably not more than 250 men, and the 2d Battalion, 238th Infantry, was practically wiped out. The desperate attacks during the day had been carried out with a complete disregard for self-preservation, and had probably cost the Japanese 300 men killed and at least twice that number wounded.
TED Force was subsequently directed to advance south along Niumen Creek toward the Torricelli Mountains foothills to disrupt Adachi’s supply lines and flank the 18th Army. Supply challenges and dense jungle terrain initially delayed Starr’s southern movement, with his northern battalions only linking up with the southern ones by day's end. The next morning, Starr launched a southward offensive, immediately encountering fierce resistance from the 1st Battalion, 239th Regiment, which held a stubborn defense throughout the day. In response, Starr ordered his 1st Battalion to bypass the engagement and move southwest, advancing unopposed for up to 1000 yards. August 3rd proved relatively calm for Cunningham, as the 1st Battalion, 169th Regiment arrived to bolster the South Force perimeter. However, vigilance remained high in anticipation of Mano’s impending final assault.
On 1 August General Adachi learned that American forces were active in the Yakamul area. It was erroneously reported to him that this was an amphibious operation, a maneuver which the 18th Army commander had feared for some time (actually, the report referred to patrolling by the 2d Battalion, 124th Infantry, along the coast from the mouth of Niumen Creek). He therefore ordered the remaining elements of the 237th Infantry to extricate themselves from the operations in the Afua area and hurry back to Yakamul to reinforce service units in that vicinity. Events moved so rapidly that the remnants of the 237th Infantry never got to Yakamul. Instead, the advance of TED Force made it necessary for General Adachi to change his plans and accelerate a general withdrawal. Communications within forward units of the 18th Army had so broken down that it was not until 3 August that General Adachi learned of the TED Force movement across the Driniumor, although the 1st Battalion, 239th Infantry, had been in contact with TED Force since 31 July. When General Adachi did hear of the American movement, he grossly underestimated the strength of TED Force. Thinking that the American operation was being carried out by only 400 troops, General Adachi merely changed the orders of the 237th Infantry and instructed that regiment to hold the 18th Army's crossing point on the upper Niumen Creek. On the same day, 3 August, General Adachi issued detailed plans for the withdrawal of all 18th Army units to the east side of the Driniumor, a withdrawal which was to begin on 4 or 5 August. The 66th Infantry, 51st Division, was to protect the 20th and 41st Division units as they crossed the Driniumor. The continued advance of TED Force on 3 August prompted General Adachi to change his plans and early on the 4th he ordered the 20th Division to start retreating at noon that day and the 41st Division to break contact on the 5th.
The following morning, elements of the 238th and 239th Regiments emerged from the jungle southwest of the 1st Squadron in a final, desperate charge. Violent action continued in front of the 1st Squadron for about two hours, during which time nearly 200 Japanese were killed at the very edge of the squadron perimeter, principally by machine gun and rifle fire. How many more of the enemy were killed by artillery and mortar fire during the period cannot be estimated, but the banzai tactics undoubtedly cost the Japanese more than the 200 dead counted in front of the 1st Squadron which, in the same two hours, lost only 3 men killed and 4 wounded. By 0900 the last enemy attacks had ceased and the remaining Japanese had withdrawn generally to the south.
Following the enemy withdrawal, Troop E pursued the retreating Japanese southward, encountering sporadic rifle fire as they eliminated remaining stragglers. The terrain encountered on August 4 and subsequent days during the operations of the TED Force east of the Driniumor proved next to impassable. Dense jungle undergrowth covered the ground; the area was thick with heavy rain forest; low but knifelike ridges, separated from each other by deep gullies, were encountered; and swampy spots were plentiful. To add to the difficulties, rain fell during the day--a downpour which turned much of the ground into a quagmire and flooded many dry stream beds. A few new, rough trails, recently cut by the Japanese, were found, but mud made them nearly useless as routes of advance. Low clouds coming in from the Torricelli Mountains to the south prevented ration and ammunition drops and increased communication difficulties. Battalions ran low on drinking water, for weather conditions prevented resupply of water purification tablets and the assault companies had neither time nor equipment to clean water by other means. Radio communication between battalions, from battalions to TED Force headquarters, and from the latter to higher echelons was nearly nonexistent, for the heavy jungle and the damp weather cut down the efficiency of all radio equipment.
It had been hoped that the advance on the 4th would carry TED Force south to the main Japanese supply route, but the trail reached by Burns', Lewis', and Williams' battalions was another route which had not been used by military traffic for some time. Possibly, it was a section of the native trail to Afua and, as such, purposely avoided by the Japanese inasmuch as parts of it could be seen from the air. In any case, the track cut on the 4th lay about 1,200 yards north of the east-west trail which most of the Japanese forces moving to and from the Afua area had been using. Colonel Starr, realizing that the main Japanese supply route had not yet been severed, ordered his units to continue southward on the 5th, on which day the advance was resumed about 0800 hours with Williams leading and Lewis' battalion about 400 yards to the rear. Pushing south along now precipitous and mountainous banks of the upper Niumen, Williams' unit was opposed by only scattered rifle fire until 1100, when it was decisively halted by a strong Japanese force conducting a stubborn defense. On August 5, learning that TED Force was approaching the point at which the 18th Army's main line of communications crossed the upper reaches of Niumen Creek, General Adachi had also ordered the 8th Independent Engineers to aid the remnants of the 237th Infantry in holding the crossing point. It was this combined 237th Infantry-8th Engineers force that Williams' 3d Battalion, 124th Infantry, had encountered about 1100 on 5 August. The composite Japanese unit was dug in along a 1,000-foot high ridge across Williams' line of advance and threatened to outflank the battalion by occupying other high ground nearby. Despite artillery and mortar support, Williams' men were unable to advance. Colonel Starr ordered Lewis' unit to bypass the fight and continue south to locate and cut the Japanese main supply route. Fighting at Williams' front continued through most of the afternoon, and Colonel Starr realized that the Japanese force could not be dislodged that day. Fowlers' battalion was brought up to the rear of Williams' and late in the afternoon set up a new perimeter with the regimental command post. Before dark, Williams' men withdrew slightly from their most forward positions so that artillery concentrations could be placed along the front. Lewis' unit, which had moved off to the southeast to bypass Williams' fight, made little progress in very rough terrain and was cut off from the rest of TED Force before it could swing westward.
Meanwhile, another battalion to the west encountered minimal resistance as it intercepted the main enemy trail east of the Driniumor, linking up with patrols from Cunningham’s 2nd Squadron. Action on the 6th started earlier than TED Force expected. About 0300 approximately 400 Japanese attacked Williams' perimeter. This enemy force comprised elements of the 41st Division, supported by men of the 26th Field Artillery of the 20th Division and some remnants of the 8th Independent Engineers. Attacking under cover of fire from machine guns, mortars, and 75-mm. mountain guns, the Japanese force was attempting to secure fords over the upper reaches of Niumen Creek and protect the withdrawal of other elements of 18th Army units from Afua. Though surprised, Williams' men held back the initial onslaught. Reportedly, Japanese riflemen then climbed trees surrounding Williams' perimeter to pin down the American troops while other Japanese continued to attack on the ground.
Fowler's unit, under orders to bypass Williams' fight and move around the enemy left, started moving about 0800 hours but soon found the terrain made it impossible to avoid contact with the Japanese opposing Williams. The Japanese, having control of most commanding ground in the area, stopped Fowler's leading company. Action was not rapid. The terrain made all movements slow and laborious, and much time had to be taken to co-ordinate artillery support fire properly. Under cover of artillery fire, another company of Fowler's battalion, creeping slowly through ravines and up an almost vertical cliff, worked around to unoccupied high ground on the Japanese left. The rest of the battalion was successfully disengaged to secure more commanding terrain in the same area. The Japanese, finding themselves outflanked and subjected to increasingly heavy artillery and mortar fire, began to withdraw southward in midafternoon, relieving the pressure on Williams' front. Fowler's battalion, in enveloping the Japanese left, had moved north and then westward and the maneuver had carried the unit by dark to a point just north of the main trail about 750 yards east of Burns' battalion. Williams' men withdrew to reorganize, after disengaging from the enemy forces late in the afternoon; at dark, having resumed the march westward, they secured high ground north of the trail. The ground covered during the day by Williams' battalion was little more than 500 yards west of the position it had occupied the previous night. The unit probably could have moved farther, but Colonel Starr halted it so as not to increase the distance from Lewis' battalion which was, in effect, lost. The unit had laboriously struggled over extremely rough and trackless ground during the day, fighting in the afternoon against a number of Japanese who had withdrawn from Williams' front. For the night, Lewis' men set up a perimeter about 800 yards south-southeast of the scene of Williams' fighting. With Adachi’s escape route blocked, Starr’s battalions advanced southwestward, achieving notable success by killing around 500 Japanese soldiers between August 6 and 7.
In the interim, Cunningham’s South Force completed operations in their sector, achieving a successful attack led by Howe that ousted the remaining disorganized Japanese presence from Afua on August 6. Two days later, the 124th Regiment advanced to the Driniumor, claiming to have eliminated approximately 1800 Japanese soldiers since the start of their counteroffensive, at the cost of 50 men killed and 80 wounded. With the rest of Adachi’s 18th Army retreating towards Wewak, General Gill declared Afua secure by the evening of August 9. Following the conclusion of the Battle of the Driniumor River, the fatigued units of the 32nd Division, including the 124th Regiment and 112th Cavalry Regiment, were relieved by units from Wing’s 43rd Division. From August 16 to 25, Wing’s regiments conducted final combat missions in the Aitape region, encountering minimal Japanese resistance east of the Driniumor, except for delaying actions near the mouth of the Dandriwad River by patrols of the 103rd Regiment. Consequently, General Krueger declared the Aitape operation concluded on August 25, confident that the 18th Army posed no further threat to the Tadji airstrips. Adachi’s forces had indeed suffered a decisive and costly defeat, rendering them incapable of posing a significant threat to Allied forces anywhere in New Guinea. The campaign to secure the Aitape area and defeat the 18th Army resulted in approximately 440 Allied soldiers killed, 2550 wounded, and 10 missing, while inflicting losses of around 8821 Japanese killed and 98 captured, including 2669 killed and 34 taken prisoner from August 2 to 9 alone. Adachi himself reported losing 9000 men and virtually annihilating seven regiments.

The American forces under Hall and Cunningham repelled multiple fierce Japanese offensives, inflicting heavy casualties. Despite a lot of setbacks and logistical challenges, TED Force advanced southward, disrupting Japanese supply lines and forcing their withdrawal by early August. Casualties were significant on both sides, underscoring the fierce nature of fighting on Green Hell.

- 143 - Pacific War Podcast - Fall of Myitkyina 12 - August 19, 1944
13 aug· The Pacific War - week by week
Last time we spoke about the fall of Guam and actions in New Guinea. General Shepherd's Marines had secured the Orote Peninsula, while General Turnage's Marines pushed the Japanese northwards. General Bruce's 77th Division prepared for an eastward assault, and engineers attempted, but failed, to build a supply road to Yona. Geiger's offensive began on July 31, with Marines quickly capturing Agaña and advancing despite dense jungle and resistance. The 77th Division faced tough terrain but liberated 2,000 Guamanians. The push north continued, facing logistical challenges and mined roads. By August 7th, coordinated attacks cleared key areas, culminating in the defeat of remaining Japanese forces by August 11. Guam was back in American hands although scattered Japanese forces continued guerrilla warfare until the war's conclusion. Thus the Marianas campaign had finally come to a conclusion, and now the allies were adding more bass of operation to hit the Japanese home islands.
This episode is the Fall of Myitkyina

This week we are diving back over to the northern Burma front. Despite holding Myitkyina through a rainy, muddy summer-long siege, by late July, the Japanese had been gradually cornered into a small perimeter, cut off from all supply lines and running short on ammunition. The situation worsened due to a leadership crisis, between the two Japanese leaders was a matter of semantics. Colonel Maruyama of the 114th Regiment who was in charge of the defense of the city, interpreted his orders to “facilitate the future operations of 33rd Army ‘by securing the vital areas in the vicinity of Myitkyina’,” as a call to defend the city street-by-street, house-by-house. When General Minakami of the 56th Division arrived, he pointed out that all Maruyama had to do to satisfy his orders was simply to continue to deny the Allies access to the Ledo-Kamaing road. Minakami thus found himself in a rather difficult position in regard to the command of the Myitkyina Garrison. Maruyama had conducted an excellent defense, was fully familiar with the situation and, because of his position as former commander, exercised considerable authority. Shortly after Minakami’s assumption of command, General Honda asked how long Myitkyina could stand. Minakami replied that the garrison might be able to hold out for as long as two months. A few days later, Honda was surprised to receive a second message stating, "The Myitkyina Garrison finds it difficult to hold with the poor defense facilities and meager supplies of ammunition." The Army staff concluded that the first message was undoubtedly Minakami's personal opinion as it reflected his determined character and that the second message incorporated the views of Maruyama who was more cognizant of the actual situation. In order that there should be no doubt as to the importance of holding Myitkyina, Honda sent the following message, "Maj. Gen. Minakami will defend Myitkyina to the death” — a message sent with deep regret and sadness according to the staff officers who wrote and dispatched the order.
Heavy casualties had reduced the Japanese forces from around 3,000 to fewer than 1,500, further weakening the garrison's defensive capabilities. This number included the heavily wounded and hospital patients, who could only be evacuated by drifting down the Irrawaddy River on rafts, often intercepted by the unforgiving Kachin Levies. On July 24, eight rafts and a boat laden with Japanese were attacked on the Irrawaddy by Kachins of the OSS Detachment 101. Twenty-four Japanese were killed, two captured, and then it was learned these were hospital patients fleeing Myitkyina. Three more Japanese seized by friendly Burmans revealed that hospital patients were being evacuated by the simple expedient of letting them drift down the river on rafts.
As these fierce defenders began to falter, General Wessels felt ready to launch his final push. Reinforced by the 149th and 90th Regiments, the American-Chinese forces made daily gains of several hundred yards during the last days of July, though at a significant cost. As the Japanese-held area shrank, counterattacks became less dynamic, captured positions were less fortified, and many Japanese dead were found to be severely wounded men returned to the line. Unbeknownst to the Americans, the desperate defenders had requested a withdrawal to the east by the end of the month. Though Minakami had intended to fight to the last, he ultimately agreed to preserve his men’s lives. On the night of August 1, the Japanese began their escape, crossing the Irrawaddy east of the town.
Weighing the many evidences that control of the situation was rapidly passing into their hands, Wessels and his colleagues drafted a new plan of attack. It included an ingenious device, credited to General Pan Yu-kun of the 50th Division. A raiding party, formed into fifteen heavily armed sections, was organized and briefed on infiltrating Japanese lines facing the 50th Division. Having made its way through the Japanese lines in darkness, it was to remain hidden until 0430 when the 50th would assault while the raiders spread confusion behind the Japanese lines. Meanwhile, air reconnaissance revealed many rafts moored against the Irrawaddy within the Japanese lines. "At 0300 hours (3 August), when the moon went down and rain and thunder set in, the raiding party of the 50th Division moved out. The approach was detected only once and some shots were fired at the raiders, who hit the ground. The Chinese did not return fire however, and after laying low for a while, moved out again quietly and cautiously."
While the raiders created confusion behind Japanese lines, the 50th Division launched a full attack, quickly overwhelming the remaining enemy positions and capturing 187 prisoners, thus securing Myitkyina for the Chinese. However, about 800 Japanese managed to escape eastward and later rejoined their allies. Minakami was not among them. As the 3rd of August meandered on in a haze of gunfire, blood and rain, Minakami went to sit with his back against a tree. There came the sound of a pistol shot. Japanese officers nearby sprinted to the scene. The general’s orderly was in tears. They found Minakami’s body erect against the tree trunk, facing northeast, towards Japan. The ten-week siege resulted in approximately 3,000 Japanese killed or captured; 972 Chinese killed, 3,184 wounded, and 188 evacuated due to illness; and 272 Americans killed, 955 wounded, and 980 evacuated sick. Overall, the total American-Chinese casualties in 1944 amounted to 13,618 Chinese and 1,327 American casualties. A week later, the Galahad Unit, reduced to only 130 combat-effective men from the original 2,997, was disbanded.
The fall of Myitkyina was General Stilwell’s greatest victory, earning him a promotion to full general on August 1, two days before the city fell. The attack was costly in terms of suffering and losses, but the Mogaung-Myitkyina area was a significant prize. It allowed Ledo Road builders and American transport planes to move to Myitkyina and enabled ground forces to link up with other Chinese forces in neighboring Yunnan. As the fighting moved further south down the Hukawng and Mogaung valleys, it became safer for transports to use the lower, more southerly routes to China. This, in turn, increased Hump deliveries to China from 13,686 tons in May to 18,235 tons in June and 25,454 tons in July.
While the Allies celebrated victories in northern Burma, the situation in China was dire as the Ichi-Go offensive resulted in many Chinese casualties. By August 1, General Yokoyama had amassed 110,000 troops around Hengyang, equipped with five heavy artillery pieces, fifty mountain artillery pieces, and 40,000 shells. Conversely, General Fang’s resilient defenders had dwindled to 3,000 exhausted troops, with their defenses largely destroyed. General Xue Yue’s reinforcements had failed to reach Hengyang, leaving the Chinese forces to rely on the 46th Army to launch an attack along the railway.
On August 4, Yokoyama initiated his main offensive. The 68th and 116th Divisions launched a significant assault from the south and southwest, while the 58th Division quietly positioned itself near the enemy’s northern defenses. Initially, progress was slow. However, by August 5, Yokoyama’s forces had captured Yoping and School Hill. The next day, the 116th Division secured part of the city's defenses. On August 6, the 58th Division breached the city walls from the north, forcing Fang to redeploy troops to counter this new threat. Intense street fighting broke out on August 7 as the defenders valiantly tried to repel the Japanese attacks. By nightfall, the 68th Division had overrun the southern defenses and entered part of the Walled City. Gradually, enemy troops began to surrender, and before dawn on August 8, after 48 days of fierce resistance, Fang was compelled to surrender.
Following the capture of Hengyang, Yokoyama declared the successful completion of the initial phase of Operation Togo and promptly began preparations for the subsequent offensive. In this phase, the Japanese reported casualties of over 3860 killed, 8327 wounded, and 7099 sick, with an estimated Chinese casualty count exceeding 100,000, including 8400 killed and 5000 captured in Hengyang alone. To spearhead the next stage of Operation Togo targeting Guilin and Liuzhou, General Okamura Yasuji's 6th Area Army was established on August 25, comprising the 11th, 23rd, and 34th Armies, along with the 27th, 40th, 64th, and 68th Divisions, alongside additional support units. This allowed General Hata to focus on countering potential American landings on the Chinese coast while Okamura directed the offensives in eastern China. Ahead of this operation, Lieutenant-General Tanaka Hisakazu of the 23rd Army initiated a preliminary offensive in late June, positioning the 23rd Independent Mixed Brigade in the northeastern sector of the Luichow Peninsula, advancing the 22nd Independent Mixed Brigade to the Tanjiang River, securing the Jiangmen area with the 22nd Division, and capturing the Qingyuan sector with the 104th Division. By late August, Yokoyama had deployed six divisions along the Shuangfeng-Leiyang line, poised to eliminate the enemy in the district west of Hengyang. On August 29, he launched the offensive, with over 100,000 troops advancing southwest amidst heavy artillery bombardment. Intense ground and aerial combat ensued, resulting in the loss of 10 Japanese planes and 15 enemy aircraft. Despite fierce resistance from Chinese defenders over three days, their entire line collapsed on September 1, prompting a retreat towards Shaoyang, Qiyang, and Jiahe.
However, the Japanese advanced relentlessly, covering nearly 100 kilometers in the following days without pause. By September 5, both Qiyang and Huochangpingzhen had fallen, followed by the seizure of Lingling Airdrome on September 8 by the 3rd Division. Progressing along a north-south axis, Japanese forces secured Shaoyang and Changning, while the 58th Division captured Dongan on the same day. With initial objectives achieved, Yokoyama ordered further pursuit, with the 3rd and 54th Divisions converging in the Quanzhou area by September 14. Meanwhile, Tanaka prepared for his offensive, with the bulk of the 104th Division moving towards Taipingzhen, and a raiding unit conducting a wide envelopment maneuver along the Zhukeng-Huaiji road towards Wuzhou by September 6. Subsequently, the 23rd Brigade began its northward march from Suixi. However, Tanaka's offensive wouldn't commence for a couple of weeks.
Turning to the broader context of the Pacific War, General Stilwell celebrated a major victory with the fall of Myitkyina, while General Slim's successful defense against Operation U-Go further bolstered Allied morale in the CBI Theater. In Thailand, Prime Minister Phibun's regime faced a significant crisis as Japan struggled to meet the country's essential import needs, leading to inflation, rationing, shortages, black markets, smuggling, corruption, and profiteering. The anti-Japanese Free Thai underground movement, spearheaded by Regent Pridi Banomyong, infiltrated the government, stoking public discontent against both the Japanese occupiers and Phibun's administration.
As a result, following the downfall of the Tojo government, Phibun found himself compelled to step down in late July. For his part, Phibun also was thinking of ways, he claims, to prepare to turn against the Japanese. Part of these preparations included proposals to move the capital to remote Phetchabun, north of Bangkok, and construct a “Buddhist City,” a sort of center for world Buddhism, near Saraburi—both grandiose projects in typically extravagant Phibun style. Moving to the isolated, mountain-ringed Phetchabun, Phibun later argued, would facilitate a Thai uprising against the Japanese. Yet on July 18, the Tojo government in Japan resigned, and only six days later the Thai National Assembly turned down both government bills and forced the resignation of Phibun as prime minister. The deputies in the assembly voted against these plans motivated in part by the fall of Tojo, who was closely associated in their minds with Phibun, in part by their feeling that the war was turning against Japan, and in part by their feeling that Phibun was too closely identified with an authoritarian past that must now be buried for the sake of improving relations with the Allies.
Politician Khuang Aphaiwong then assumed his position as Prime Minister on August 1. Serving as a compromise candidate, he navigated between Phibun's supporters and the opposition while maintaining cooperation with the Japanese and safeguarding Free Thai members who had collaborated with the Allies. Meanwhile, in China, the success of Operation Ichi-Go led to another leadership crisis. Despite the initial rejection of Stilwell commanding troops in China in 1942, the effective Japanese offensive posed a threat of defeat to the Chinese Government, reigniting the debate over command authority. This was especially significant as Chinese troops under Stilwell’s command were achieving significant victories in northern Burma. However, Stilwell's vocal criticism of Chiang Kai-Shek’s corrupt regime and incompetent generals strained their relationship. Chiang favored General Chennault, who proposed that with a monthly allocation of 10,000 tons for operations in northern China, his 14th Air Force could halt the Japanese offensive. Despite his strained relationship with Chennault, Stilwell redirected Hump allocations to increase the 14th Air Force's allocation to 8,425 tons, although he couldn't secure an additional 1,500 tons from the Matterhorn allocation. Chennault's aircraft managed to disrupt the Japanese advance, but failed to halt it completely. In late June, Stilwell faced criticism when Vice-President Henry Wallace visited Chongqing. While Wallace persuaded Chiang to allow a small American observer mission into Communist territory, he also recommended Stilwell's recall due to his perceived lack of diplomacy and strained relations with the Chinese leadership.
Nonetheless, Stilwell maintained the backing of the Joint Chiefs of Staff, and President Roosevelt eventually nominated him to lead the China Theater, on the condition that he make every effort to avoid upsetting the Generalissimo. In July, the President attempted to persuade Chiang to accept this arrangement, but the Generalissimo employed various diplomatic maneuvers to reject the proposal, agreeing "in principle" only after an unspecified period for his forces to adjust. He also requested the presence of a presidential representative to facilitate smooth relations between himself and Stilwell. Major-General Patrick Hurley was appointed to this role and arrived in China in August. Concurrently, the Dixie Mission arrived in Yan'an, where over the following months, American observers assessed Communist society, military tactics, and guerrilla operations, issuing reports that commended them and suggested increased collaboration.
Following the fall of Hengyang, tensions escalated in China, with rumors swirling about potential coup plans involving Marshall Li Zhongren and General Xue Yue against the Generalissimo. Meanwhile, Chennault urged Stilwell to divert Hump airlift capacity to supply ground forces in eastern China, a move opposed by Chiang, who feared supporting potential insurgents with lend-lease equipment. Stilwell, anticipating his imminent assumption of leadership in the China Theater, refrained from challenging Chiang's stance. With significant developments looming, the intensifying rift between Stilwell and Chiang foreshadowed the downfall of one of them.
Elsewhere in the South Pacific, General MacArthur’s troops had finished their final offensive in New Guinea and were preparing to return to the Philippines by way of an intermediate stop at Halmahera Island. To the east, Rabaul was completely surrounded, enduring heavy bombardment from Allied air forces. Meanwhile, on Bougainville, the remaining forces of the 17th Army had retreated to the island's southern region, unable to launch further counterattacks. The living conditions of the Japanese soldiers, never good under the best of circumstances, became increasingly desperate. Added to the dangers that forward troops always faced, such as contact with large American combat patrols, was the growing specter of starvation. Sealed off from regular supplies from New Ireland or New Britain, General Hyakutake's army had to depend entirely on its own laborers to acquire food. The normal rice ration of 750 grams of rice for each soldier was cut in April 1944 to 250 grams, and beginning in September there was no rice ration. A large portion of the available army and naval personnel had to be put to work growing food. Allied pilots took delight in dropping napalm on these garden plots whenever possible. The native workers who had been impressed into service were the first to defect, but soon many soldiers also just walked away from their units, taking the chance of surviving in the jungle on what could be gathered. After the failure of the March attack, morale in most units became deplorably low. There were instances, normally unimagined in the Japanese army, of open insubordination and even mutiny. Although General Hyakutake dreamed of a midsummer offensive, it became obvious that no operations as large as that smashed in March could be undertaken for months, if ever. Thus, almost as if by agreement, both sides adopted a defensive posture that minimized the conflict in the no-man's-land between them.
In the Central Pacific, significant progress had been made over the past year, marked by the complete capture of the Gilbert, Marshall, and Mariana Islands, strengthening the Allied presence and providing a launching point for future offensives into the heart of the Japanese Empire. The next target for Admiral Nimitz was the Palaus, to be invaded concurrently with Halmahera. However, the architect of this southwestern advance was not Admiral Spruance, who had been overseeing operations with the 5th Fleet. Instead, it was Admiral Halsey’s 3rd Fleet, known as the "Department of Dirty Tricks," that had been strategizing the next moves from Hawaii. Now, Admiral Halsey was set to assume command of the Pacific Fleet, leading the charge to the Palaus and the Philippines. This rotation in leadership between Halsey’s 3rd Fleet and Spruance’s 5th Fleet was orchestrated by Nimitz to maintain operational tempo and confuse the Japanese. The alternating command structure allowed for continuous planning of future operations while the active fleet conducted current ones.
However, Tokyo was apprehensive about a potential invasion of the Philippines and sought to bolster its defenses. Following the surrender of the US Army Forces in the Philippines, the 14th Army, led by Lieutenant-General Tanaka Shizuichi, worked to establish military administration, secure cooperation from civilian institutions, and quell guerrilla groups across the countryside. Despite their endeavors, their control over certain regions, particularly in the Visayas and Mindanao, remained fragile. Allied submarines and aircraft from Australia and New Guinea also delivered supplies like signal equipment, weapons, explosives, propaganda materials, and counterfeit currency to support the guerrilla forces, further impeding Japanese efforts. Additionally, with the deteriorating situation in the South and Central Pacific, more troops were redirected from the Philippines’ garrison to other areas, weakening the 14th Army, now commanded by Lieutenant-General Kuroda Shigenori since May 19, 1943. Undermanned and stretched thin, the Japanese halted their suppression operations in August, hoping that the imminent declaration of independence by the Second Philippine Republic would lead guerrillas to surrender. However, this strategy backfired, as the guerrillas only grew stronger during the pause. Consequently, Kuroda restarted intensive suppression operations in 1944, but guerrilla activities escalated in anticipation of the imminent liberation by American forces. As a result, the guerrillas gained strength in the following months, providing valuable intelligence to MacArthur’s forces in preparation for their eventual return. Given this context, it was evident that the 14th Army would be ill-equipped to withstand an American invasion under the current circumstances.
Due to its crucial strategic location bridging Japan and the southern region rich in natural resources, Japan couldn't risk losing the Philippines. It served as their primary rear base supporting the main defense perimeter. The Philippines were also to play the role of a rear base of operations–an assembly and staging area for troops and supplies and a concentration area for air reserves, to support operations at any threatened point on the main defense perimeter from the Marianas south to Western New Guinea and the Banda Sea area. To implement these plans, IGHQ in October 1943 directed the 14th Army to complete the establishment of the necessary base facilities by the spring of 1944. Major emphasis in this program was laid upon the construction of air bases. The Army alone planned to build or improve 30 fields in addition to 13 already in operational use or partially completed. The Navy projected 21 fields and seaplane bases to be ready for operational use by the end of 1944, expanding its total number of Philippine bases to 33. Line of communications and other rear area base installations were also to be expanded and improved. Of the 30 Army airfields projected in October 1943, six had been generally completed by May 1944, and 24 under construction. Of the 21 projected Navy fields, 15 were still incomplete by then.
Consequently, in early 1944, the decision was made to strengthen the garrison in the Philippines. Initially, this involved reorganizing and expanding existing garrison units to establish four new independent mixed brigades. These brigades were primarily tasked with suppressing guerrilla activity, while infantry divisions were assigned to defend against potential enemy landings. However, despite the estimation that at least seven divisions were necessary for the defense of Luzon, the Visayas, and Mindanao, only the 16th Division was available. Additionally, it was deemed crucial to bolster air strength with at least two air divisions, anticipating Allied invasions in Halmahera and Palau before advancing to the Philippines. Plans were formulated in March to deploy reinforcements within eight months. In mid-May, General Terauchi relocated his headquarters to Manila to oversee operations more closely. Concurrently, efforts were made to transport the 30th Division to Mindanao and bring the 4th Air Army to Manila. Furthermore, the Philippines were reinforced with the 2nd and 4th Air Divisions, the latter being tasked with constructing 30 new airfields.
In June, approximately 20,000 inexperienced replacements were transported to the Philippines to bolster the recently-formed independent mixed brigades, filling them up to division strength. Subsequently, in July, the 100th, 102nd, 103rd, and 105th Divisions were activated, along with the establishment of the 54th and 55th Independent Mixed Brigades. It's ironic that despite this reinforcement, the main Japanese forces were as inexperienced as the Philippine Army during MacArthur’s defense. Nonetheless, Terauchi was resolute in further fortifying the Philippines to prevent its fall, unlike MacArthur's situation. By mid-July, the reinforced 58th Independent Mixed Brigade arrived at Lingayen. Later that month, the 14th Army underwent reorganization into the 14th Area Army, with units directly under its command tasked with defending the northern Philippines. Meanwhile, the 35th Army, led by Lieutenant-General Suzuki Sosaki, was established under the 14th Area Army to defend Mindanao and the Visayas. Additionally, Tokyo finalized plans for decisive battle operations, codenamed Sho-Go, covering the Philippines-Formosa-Ryukyus-Japan-Kuriles area. This determined the disposition of Army and Navy air forces across the Pacific, with the Philippines receiving the reorganized 1st and 2nd Air Fleets and the 4th Air Army. The Philippine garrison was strengthened to a total of nine divisions and four brigades, with the 1st Division at Shanghai and the 68th Independent Brigade at Formosa designated as general reserves. Defenses and fortifications were constructed at Luzon in preparation for the decisive battle there.
Known as the Combined Fleet Top Secret Operations Order No. 84, issued on 1 August, this fixed the new tactical grouping of naval forces for the Sho-Go Operations. Almost the entire surface combat strength of the Fleet was included in a Task Force placed under the overall command of the First Mobile Fleet Commander, ViceAdm. Ozawa Jisaburo. This force was broken down into three tactical groups: (1) the Task Force Main Body, directly commanded by ViceAdm. Ozawa and consisting of most of the Third Fleet (carrier forces): (2) the First Striking Force, commanded by Vice Adm. Kurita Takeo and made up of the Second Fleet with part of the 10th Destroyer Squadron attached: (3) the Second Striking Force, commanded by Vice Adm. Shima Kiyohide and composed of the Fifth Fleet plus two destroyer divisions and the battleships Fuso and Yamashiro. The First Striking Force would be stationed at Lingga Anchorage, while the Task Force Main Body and the Second Striking Force would be stationed in the western part of the Inland Sea. However, if an enemy attack was expected, the First Striking Force would advance from Lingga Anchorage to Brunei, Coron or Guimaras while the Task Force Main Body and the Second Striking Force remained in the Inland Sea and prepared to attack the north flank of the enemy task force. During August, the Navy Section of Imperial General Headquarters also took action to give the Combined Fleet more unified operational control of naval forces in order to facilitate the execution of the Sho-Go plans. On 9 August the General Escort Command and units assigned to naval stations were placed under operational command of the Combined Fleet, and on 21 August the China Area Fleet was similarly placed under Combined Fleet command. On 10 August the 1st Carrier Division, reorganized around two newly-commissioned regular carriers, was added to the Task Force Main Body. Vice Adm. Ozawa, Task Force Commander, meanwhile set 15 October as the target date for completion of the reorganization and training of the 3d and 4th Carrier Division air groups. Concurrently with these preparations, steps were taken to strengthen the antiaircraft armament of combat units.
Accordingly, the Japanese sought to deploy the 8th and 26th Divisions, the 2nd Tank Division, and the 61st Independent Mixed Brigade to the Luzon region for a decisive battle. However, enemy submarines posed a constant threat. Since February, they had been patrolling the South China Sea, targeting the Hi Convoys supplying Japanese territories in Southeast Asia and Japan itself. During these engagements, Admiral Ijuin was killed aboard the patrol boat Iki. Between August 18 and 25, Admiral Kajioka's Hi-71 convoy, carrying the 26th Division, was attacked by six American submarines. The escort carrier Taiyo, destroyers Yunagi and Asakaze, two oilers, four transports, and three kaibokans were sunk, with 7420 soldiers of the 26th Division lost. The submarine Harder was the only American vessel sunk in retaliation. Kajioka's Hi-72 convoy, returning from Luzon, was also attacked, resulting in the sinking of his flagship, the kaibokan Hirato, and the loss of the destroyer Shikinami, three transports, and one oiler. Despite these setbacks, advance units of the 8th Division, 2nd Tank Division, and 61st Independent Mixed Brigade successfully reached the Philippines in September.

After months the siege of Myitkyina had finally ended. The Japanese had held out as long as they could, but lack of supplies and rather terrible leadership lost them the fight. Meanwhile, in China, Japanese offensives intensified, challenging Chinese defenses and leadership. It seemed war was coming to the Philippines, where the Japanese prepared to fight to the death.

- 142 - Pacific War Podcast - Fall of Guam August 5 - August 12, 1944
6 aug· The Pacific War - week by week
Last time we spoke about fall of Tinian and battle of Sansapor. Following the capture of Noemfoor and Biak, the Allies advanced to the Vogelkop Peninsula, constructing vital airbases. MacArthur initially focused on seizing Sorong and Waigeo Island, but operations accelerated, making Klamono oilfields non-viable, and oil rehabilitation projects in the Dutch East Indies were prioritized by the Joint Chiefs of Staff. MacArthur planned reconnaissance in the Mar-Sansapor area. The 6th Division launched Operation Typhoon, and Task Force 77 executed landings on July 30, 1944. Airfields were built, and patrols eliminated Japanese forces. Meanwhile, Tinian saw intense fighting, with Marines securing key objectives by July 31. Following massive bombardments, Marines continued advancing, encountering heavy resistance but eventually declaring Tinian secure on August 1. Guam operations saw similar advances with coordinated attacks overcoming Japanese defenses.
This episode is the Fall of Guam

This weeks podcast brings us back into the intense action in Guam. As we previously observed in Guam, General Shepherd’s Marine brigade had effectively captured the Orote Peninsula, while General Turnage’s 3rd Marine Division had reached the designated beachhead line, pushing back a weakened Japanese force retreating northward. Meanwhile, General Bruce’s 77th Division maintained control of the southern beachhead line, preparing for a general eastward assault. An engineer battalion began constructing a supply road towards Yona, a project that ultimately failed to support the infantry's advance.
On July 30, Turnage’s Marines and the infantrymen sent patrols to gauge the strength of the Japanese forces, but dense foliage obscured enemy movements. Geiger eventually concluded that defensive positions were likely near the Agaña-Pago Bay Road. He planned an initial advance toward the general line of Agaña-Famja-Pago Bay, followed by a northeastward attack. Turnage’s Marines were assigned to capture the capital, Agaña, and the strategic Tiyan Airfield on the left, while Bruce’s infantry aimed to secure the Pago Bay area on the right.
Following two days of intense artillery and naval bombardment, Geiger’s offensive commenced at 06:30 on July 31. On the left, Turnage’s units encountered minimal resistance. The 3rd Marines, now led by Colonel James Stuart, quickly occupied the ruins of the abandoned Agaña and moved beyond the O-1 Line to secure the main northbound roads. The 21st Marines advanced through dense underbrush, reaching O-1 after neutralizing an enemy pillbox near Famja. When Lieutenant Colonel Duplantis 3rd battalion, 21st marines brought his command post forward, a curious incident occurred which illustrated the confusion of the Japanese. Someone in the battalion command group sighted one of the bypassed enemy groups, estimated to be about 15-20, led by an officer, moving toward the new CP area. The Marines held their fire, and when the small unit got to within 150 yards of the waiting men, an interpreter called to the Nipponese to surrender. Apparently thinking they had finally reached friendly lines, they started forward, then stopped to hold a hurried conference. The chattering was interrupted by the interpreter urging them forward, but by this time the aggregation had decided they were in unfriendly territory. They broke and ran in all directions; the Marines opened fire, killing and wounding about half of the intruders. Those still alive escaped into the protecting foliage. The 9th Marines destroyed a delaying detachment at Ordot and two tanks during their successful push to O-1.
Colonel Hamilton’s 1st and 3rd Battalions, along with Colonel Tanzola’s 3rd Battalion, advanced to the right, moving through steep slopes and narrow gorges in columns. They successfully reached Yona and the Pago River without encountering any opposition. With the Reconnaissance Troop protecting the south flank, General Bruce's 77th Infantry Division started toward the east coast of Guam at 7:00, 31 July. Elements of the 307th, with 3/305 attached, led the way in a column of battalions. Lack of enemy resistance permitted battalions to move with companies in column; even so, the march proved most difficult. The troops initially scaled steep slopes, slid down into narrow gorges, and followed along the foothills southwest of the central mountain range of Guam. For a time, vehicles followed, but soon the terrain became so rough that even jeeps could not traverse it. As one infantryman later wrote: “The distance across the island is not far, as the crow flies, but unluckily we can't fly. The nearest I came to flying was while descending the slippery side of a mountain in a sitting position. . . . After advancing a few yards you find that the [bolt] handle of the machine gun on your shoulder, your pack and shovel, canteens, knife, and machete all stick out at right angles and are as tenacious in their grip on the surrounding underbrush as a dozen grappling hooks. . . . The flies and mosquitos have discovered your route of march and have called up all the reinforcements including the underfed and undernourished who regard us as nothing but walking blood banks. We continue to push on. . . .”
During this movement, Hamilton’s Company L liberated 2,000 Guamanians from a concentration camp near Asinan. Soldiers willingly gave their rations and cigarettes to the undernourished men and women who were almost overcome with joy at once again seeing Americans. Men of the 77th Division soon forgot the long, tiresome cross-island march as the full realization of the expression, "liberation of enslaved peoples," came to the troops. Following the Orote operations, Shepherd’s brigade was ordered to take over the southern half of the beachhead line from Inalas to Magpo Point, relieving the 305th and 306th Regiments. On August 1, Geiger’s northward push continued, with the 305th moving to the Yona area and the 306th heading to Pago Bay. The 305th and 307th Regiments advanced slowly through rough terrain without opposition, reaching the O-2 Line by nightfall. On the left, Turnage began his advance with three regiments abreast, but the 3rd and 9th Marines eventually pinched out the 21st upon reaching the intermediate D-2A Line. At 15:00, these two regiments resumed their advance against slight resistance and reached O-2 by nightfall. The main challenge during this period was moving supplies forward, as both divisions relied on the same coastal road, heavily mined by the Japanese. With the rapid advance came the necessity to move supply distribution points closer to the front. Trucks began to roll over the already crowded coast highway to establish an advanced division dump in the Agaña Central Plaza area. Artillery units started to displace forward so that continuous direct support would be available to the assault units. This added traffic, plus the fact that the 77th Division would have to move supplies over the same road, presented a problem to the engineers. In an effort to alleviate the situation, the 25th Naval Construction Battalion and the 19th Marines put all available men to work improving existing roads and trails. Yet despite these efforts, by August 1, the problem of getting supplies forward was becoming more serious. The main coast road –and only one that ran from west to east on northern Guam– over which all traffic had to move had been heavily mined. The Japanese had placed aerial bombs and single-horned mines at road junctions and intersections in and around Agaña. In addition to being mined and heavily congested, the two-lane, hard-surfaced Agaña-Pago Bay Road was overused, poorly maintained and, with frequent rain, soon deteriorated badly. In the end, the engineers could not properly maintain the road and still allow the essential supply convoys through. On the morning of August 2, artillery and warships bombed the new positions General Obata was trying to establish around Mount Santa Rosa. Meanwhile, the Marines and infantrymen continued their pursuit northwards, aiming to reach the O-3 Line behind Japanese delaying positions at Finegayan and Mount Barrigada.
On the left, the 9th Marines swiftly captured Tiyan Airfield, but their advance was hampered by dense jungle. Despite this, they managed to gain 1800 yards while the 21st Marines cleared the Saupon Point-Ypao Point area of small enemy groups. On the right, the 77th Division's advance was initially covered by a 14-tank patrol conducting reconnaissance in the Barrigada area, where they faced heavy resistance. The 307th Regiment quickly secured Price Road, but Tanzola’s 3rd Battalion was halted by concealed machine-gun positions near Barrigada Well. Subsequently, the 307th, now led by Lieutenant-Colonel Thomas Manuel, was also stopped near the village, with Manuel’s 1st and 3rd Battalions becoming mixed up just as an enemy tank broke through their lines. After numerous failed attempts to dislodge the enemy, Companies G and E managed to penetrate the Japanese lines in the afternoon, although Company G had to be evacuated by nightfall. Meanwhile, the 305th moved up and consolidated its lines with the 307th. Since Bruce’s infantrymen failed to link up with the Marines, Colonel Butler’s 2nd Battalion was sent to fill the gap between the divisions. Following a reorganization, the 305th and 307th Regiments attacked again the next morning, encountering surprisingly little resistance as they moved through Barrigada and secured the vital well. The 77th Division had a special reason for wanting to reach Barrigada quickly. The reservoir and pump, located 100 yards northwest of Road Junction 306, could supply 20000 gallons of water daily to the troops. Until now, the men of the division had quenched their thirst by getting water from streams and creeks. But in the northern part of Guam there were no streams, and the reservoir would be the only source of supply. With tanks leading the way, Manuel’s 3rd Battalion advanced quickly and reached the summit of Mount Barrigada, although the 2nd Battalion lagged behind. Meanwhile, the 305th Regiment engaged in several isolated skirmishes but still managed to link up with the 307th.
To the left, Turnage had also resumed his advance toward O-3. Although the 3rd Marines encountered little resistance and reached their objective successfully, Colonel Craig’s 1st Battalion was halted by heavy fire near Finegayan after destroying a Japanese stronghold. That night, the Marines faced mortar and tank attacks, but these assaults made little progress. Meanwhile, as the 22nd Marines patrolled southern Guam, the 4th Regiment was held in reserve at Toto. On August 4, the remainder of Shepherd’s brigade began moving to Toto, leaving only Colonel Schneider’s 1st Battalion and the 6th Defense Battalion behind. Following Turnage’s orders, the 21st Marines were positioned between the other two regiments to reach O-3 near Dededo. At the same time, Craig’s 1st Battalion made minimal gains toward Finegayan, while the rest of the 9th Marines advanced to O-3 and successfully severed the Finegayan-Barrigada Road. To the right, Bruce’s infantrymen, following an artillery barrage, advanced to O-3, overcoming terrain difficulties and securing the objective line by nightfall. On August 5, Turnage’s three regiments continued their advance, pushing past O-3. The 3rd Marines reached Amantes Point, and Craig’s 1st Battalion finally overran the remaining Japanese positions at Finegayan. Behind them, Shepherd’s brigade moved to Dededo, preparing to take over the left flank for the final push. Meanwhile, as the 306th Regiment relieved the exhausted 307th, Tanzola’s men continued to fight through the dense jungle, with his 2nd Battalion reaching the O-4 Line by nightfall.
During a nighttime raid, the 1st Battalion was targeted, resulting in 48 casualties. Following this, the 2nd Battalion encountered the tanks the next morning, eventually neutralizing them but suffering an additional 46 casualties. Bruce’s regiments gathered at O-4 to prepare for an attack on Mount Santa Rosa, where Obata had concentrated his forces. Turnage’s regiments also resumed their attack, advancing with minimal resistance. Geiger initiated the final push on August 7, with Turnage’s Marines facing minor obstacles due to jungle terrain. Despite this, the 3rd Marine Division reached the O-5 Line by nightfall. Shepherd’s brigade swiftly progressed along the coast, joining forces with the 3rd Marines. Meanwhile, the 306th and 307th Regiments prepared for a coordinated attack. Bruce's strategy involved the 306th securing ground north of the Japanese defensive lines, the 307th leading a tank-infantry assault on Yigo, and the 305th closing in on Mount Santa Rosa. Once each objective was secured, Santa Rosa would be encircled from Anao to Lumuna Point, leaving the enemy with no escape route except into the sea.
By midday, despite facing delays from the narrow road and enemy sniper activity, Manuel's tanks surged ahead of the infantry, veering right to swiftly eliminate several Japanese machine-gun positions at the road's edge. However, their advance was halted by heavy Japanese fire from the left rear as they crested a slight elevation. In a wedge formation, commanded by Captain Seger from his tank at the right rear, the light tanks swept rapidly over the slight crest. As they pushed on there was an explosion to the left of the tanks directly in front of Seger. He radioed to Colonel Stokes: "There's a burst in front of me; could be mine or antitank gun. Call for the mediums." Just before the mediums came up more explosions sounded from the left. The tankers could not locate the source of the fire because of the dense woods to the left and the absence of flash and smoke. When the mediums reached the open area, their crews could tell that the light tanks were in trouble but they could not see where the fire was coming from. Only when they advanced up the slight rise and began themselves to have steel shrapnel and bullets smash on the left of their hulls and turrets did they turn and pour fire back into the woods at the left rear. Fifty yards behind the stricken tanks the infantrymen struggled to push through the positions by the road that the tanks had overrun. Japanese still fired from a pillbox that had been blasted by the medium tanks as they raced ahead. The troops put rifle and machine-gun fire into it. They threw six grenades before one landed inside the position. The enemy continued to fire from it. A flame-thrower man maneuvered cautiously up to the position and put the searing flame in through an opening. The heat was too much for the defenders; one of them scurried out and fell before the American guns. The enemy position, so skillfully concealed from the front but vulnerable from the rear, was built around two light tanks. Two antitank guns, two 20mm guns, six light and two heavy machine guns, plus about a makeshift battalion of infantry added their fire to make the Yigo defense formidable. One medium was hit in its gas tank. Flames shot out of the bottom and quickly enveloped the sides. The crew hastily clambered out of it just before the ammunition inside began exploding. Another tank stalled under the heavy fire. As bullets hit the vehicle, the tankers dashed for a shell hole. Some of the mediums moved on out of the area. One of them tried to sweep around to the right below the line of enemy fire and promptly threw a track. As more tanks came up, they swung their cannons and machine guns around for brief fire on the enemy positions to the left and then passed on to the objective ahead. The leading light tank had similarly been destroyed and another was destroyed shortly afterwards.
The American armor suffered losses against this well-concealed enemy position. Fortunately, Colonel Smith's 3rd Battalion, encountering minimal resistance in the jungle, directed Company K to flank the Japanese from the rear, catching them off guard and eliminating them without casualties. This enabled the 307th to secure the Yigo area and the elevated terrain to the northeast in readiness for the Santa Rosa assault. Meanwhile, the 306th consolidated west and north of Yigo, while the 305th advanced to the Lumuna Point line. The day also witnessed the inaugural combat flights of Marine planes from the newly completed Orote airfield over Guam. By nightfall, Obata dispatched his remaining tanks on a futile infantry-tank raid against the 306th, which repelled the attack successfully. On August 8, as the 305th and 307th Regiments closed in on Santa Rosa, Smith's forces continued north towards Lulog to complete the encirclement. Although the 306th captured Lulog, the 307th encountered minimal resistance in capturing Santa Rosa. Consequently, Bruce instructed Smith to push north towards Salisbury, but progress was limited by day's end.
On the left flank, Shepherd’s brigade and Turnage’s division continued their advance. The 22nd Marines progressed to Ritidian Point, establishing three roadblocks. The 4th Marines secured O-5 and advanced to RJ 462. The 21st Marines patrolled the Chaguian area, while the 3rd Marines fought through dense jungle to defeat a Japanese roadblock and reach the Salisbury-Tarague Road. Patrols returned late in the afternoon and reported few enemy contacts, but one such unit from 3/21 had discovered a Japanese truck containing the bodies of 30 native men who had been beheaded. According to the official account of the incident, the Guamanians, found near Chaguian, had not been dead more than 24 hours. The next morning another patrol found an additional 21 bodies in the jungle near the same village.
The 9th Marines faced heavy resistance as they dug in around Salisbury, close to Obata’s headquarters. A tank-infantry counterattack targeted Stuart’s 2nd Battalion at night, dispersing the enemy but necessitating retreat due to the threat of Obata’s remaining tanks. Stuart’s 3rd Battalion and Butler’s 1st Battalion attacked the next morning but found no sign of the tanks. Meanwhile, the 77th Division patrolled the Yigo-Salisbury area, and the 9th Marines advanced rapidly towards the northeastern coast before redirecting patrols to Savana Grande, where 3000 Japanese were suspected to be hiding. Following artillery bombardment, the Marines occupied Savana Grande and Pati Point but found little evidence of Japanese presence. Patrols from the 4th and 22nd Marines also reached the northern beaches, leading Shepherd to declare an end to organized resistance in the brigade zone. The last known resistance persisted in the 3rd Marines’ sector, where Obata’s tanks were last observed.
Accordingly, on August 10th, Stuart’s 2nd Battalion initiated an attack to the east, establishing contact with two tanks on the road. Swiftly disabling these tanks, the Marines pressed forward, swiftly overpowering the Japanese positions and successfully seizing a total of seven abandoned tanks. By 11:30, Geiger declared an end to organized resistance on Guam. American casualties up to this point totaled 1214 killed, 5704 wounded, and 329 missing, with 10971 Japanese reported dead. Despite this announcement, Obata persisted at Mount Mataguac, fending off Bruce’s infantry patrols since August 8th. Finally, on August 11th, Smith’s 1st Battalion launched a meticulously planned attack supported by tanks and mortar barrages, stunning the defenders and enabling soldiers to destroy cave entrances. When the caves were reopened four days later, more than 60 bodies, including General Obata’s, were found inside the well-fortified command post. Following the battle, Major-General Henry Larsen’s garrison forces maintained intensive patrols on Guam throughout the remainder of the year under close scrutiny from Island Command.
Island Command, Guam under General Larsen, had taken command of Orote Peninsula and Cabras Island on August 2 to begin base development, namely the airfield and seaport. It then assumed formal command of Guam on August 15. Island Command grew rapidly as it took over all logistics, construction, and civil affairs tasks in stages. It included the 5th Naval Construction Brigade with the 27-29th Seabee Regiments with 12 Seabee, four Army, and one Marine engineer battalions plus "Lion 6", a Navy advance base force responsible for building and operating Naval Operating Base, Guam. Island Command was also responsible for the care of 21000 Guamanian civilians and built replacement housing for 15000. Both the 3rd and 77th Divisions maintained an infantry regiment and an artillery battalion in the north to deal with diehards. Up to 80 Japanese were killed each day during the first two weeks after Guam was declared secure. The nightmare would continue for the Japanese for some time to come. The 3rd Marine Division took over sole responsibility for island defense under Island Command on August 22. The 1st Provisional Marine Brigade then departed for Guadalcanal on August 31, where it would be expanded into the 6th Marine Division to fight on Okinawa. The 3rd Marine Division finally remained on the island to train for Iwo Jima, as did the 77th for Leyte and later Okinawa.An estimated 8500 Japanese soldiers remained scattered in the jungles of the north and the mountains of the south, engaging in guerrilla warfare until the war's conclusion. However, most were either killed or captured before then. The final tally for Guam by August 1945 included 18377 Japanese killed and 1250 captured, with American losses totaling 1407 killed, 6010 wounded, and 376 missing.
By the conclusion of the Marianas Campaign, the Japanese suffered casualties exceeding 50,000, while the Americans solidified their control by positioning themselves strategically along the inner ring of Imperial defenses. This positioning enabled them to cut off the flow of supply ships and submarines that had previously supported remote enemy garrisons. Additionally, the Americans established a naval base with the capacity to support one-third of the Pacific Fleet, set up extensive forward supply depots, which posed a threat of swifter assaults on the Japanese home islands, and constructed several B-29 airfields. These airfields facilitated the unleashing of devastating aerial bombardments on Japan, bringing the full force of total war to its people through a relentless barrage of explosives and fire. That finishes up the story of the Marianas, now we need to travel back over to New Guinea.
Despite the initial success of the Japanese offensive, General Hall's forces successfully halted the enemy advance and reorganized their river line by July 15th, although there remained a 1500-yard gap in the center. Aware of this vulnerability in the American defenses, the Japanese exploited it, particularly under the cover of darkness. However, Colonel Starr's 3rd Battalion actively patrolled this area and occasionally engaged with the enemy, such as the night of July 14th when they eliminated 135 Japanese soldiers. Nonetheless, General Cunningham reported that his South Force had expanded its lines nearly 1000 yards beyond its designated sector without encountering any elements of the 124th Regiment. Consequently, on July 15th, Starr concluded that his regiment had not advanced as far south as previously thought, prompting him to order his units to adjust their positions southward and fortify their defenses along the Driniumor River towards Cunningham's Troop E location.
The next morning, the 3rd Battalion began its journey southward to close the gap. However, upon reaching the area by nightfall, Troop E came under attack from two companies of the 1st Battalion, 239th Regiment. As the cavalrymen sought cover from this assault, Starr’s 3rd Battalion also faced fire from Colonel Nara’s 3rd Battalion, which had redirected southward following its defeat at the Paup villages. This division split the American force, with Companies L and M encountering increasing resistance as they pressed southward towards South Force lines, while Companies I and K fortified their positions for the night. Despite the engagement resulting in the death of several Japanese soldiers and the narrowing of the gap to 500 yards, nightfall on the coast witnessed General Adachi’s Coastal Attack Force launching suicide banzai charges towards Anamo, only to be swiftly repelled by the defenders' lethal machine-gun fire, resulting in the complete annihilation of the force. In the rear, Colonel Howe’s 1st and 2nd Battalions were dispatched by Hall to eliminate remaining enemy units west of the Driniumor. Over the course of two days, in a series of complex and occasionally disjointed company maneuvers, the Americans successfully subdued Colonel Nara’s remaining troops in the area. Meanwhile, further south, Japanese groups were spotted crossing the Driniumor at a fording point approximately 2500 yards south of Afua, prompting Cunningham to deploy Troop A to strategic high ground behind the river to halt westward Japanese movements. There, the 78th and 80th Regiments, led by Major-General Miyake Sadahiko, were gathering in preparation for a fresh offensive.
Adachi devised a fresh strategy, envisioning Miyake's forces striking Afua from the southern front, while the 239th Regiment prepared to advance against the Kawanaka Shima area. Furthermore, the retreating 237th Regiment and the reserve 66th Regiment received orders to head south to reinforce future assaults by the 20th Division, although they wouldn't reach the destination until July 25. Meanwhile, as the Miyake Force gradually maneuvered into position on the right and rear of Cunningham’s 1st Squadron, Starr faced ongoing challenges in filling the gap in the center, eventually managing to close it by the morning of July 18. That night, Miyake finally dispatched two battalions to launch an assault on the 1st Squadron's command post and the adjacent perimeter held by Troop A, successfully pushing them back 250 yards to the northeast. However, swift reinforcements enabled Cunningham to recapture the lost ground the following morning, prompting the enemy to retreat northwest into the jungles. By afternoon, fresh Japanese units had once again encircled the Troop A position; yet, after an effective artillery barrage, the cavalrymen thwarted Adachi’s plans by pushing 600 yards to the southwest. Following this triumph, on July 21, Troop C relieved the battered Troop A; Howe’s battalions successfully established a patrol base on the East Branch of Koronal Creek; and Starr’s 2nd Battalion relocated to Palauru to enhance outer security southwest of the airfield. Concurrently, on July 19, the initial units of General Wing’s 43rd Division commenced landing at Aitape, with the 2nd Battalion, 169th Regiment subsequently assuming control of approximately 1000 yards of the river line on the right flank of the 124th Regiment by July 22.
Meanwhile, Adachi instructed the still-reorganizing Miyake Force to launch another assault on Afua from the north and west, while General Nakai’s 79th Regiment crossed the Driniumor River to strike from the south. On July 21, in the evening, Miyake initiated an attack on Troop C’s position, effectively isolating it from the remainder of South Force. Despite the cavalry's resistance against the intense Japanese onslaughts, Miyake's units successfully thwarted Cunningham’s efforts to relieve the besieged troop in the subsequent days. Faced with the threat to his command post and reluctant to divert more forces from the river defenses, Cunningham ultimately opted to establish a new defensive line 1000 yards north of Afua, consequently abandoning the town and leaving Troop C stranded.
It was not until the night of 21-22 July that the Japanese forward units were able to organize for any sort of attack. During that night, elements of the 124th Infantry received considerable mortar, machine gun, and rifle fire from east of the Driniumor. This fire increased the next morning, and about noon the 3d Battalion, 124th Infantry, was attacked from the west by elements of the 237th Infantry. The first Japanese attack was ". . . finally broken up by a bayonet charge . . ." conducted by elements of the 3d Battalion, 124th Infantry, but other attacks followed as troops of the 1st Battalion, 239th Infantry, tried to move across the Driniumor from the east, striking both the 124th Infantry's unit and part of the 2d Battalion, 169th Infantry. Before dark on the 22d, the 3d Battalion, 124th Infantry, counted 155 new Japanese dead in its area. That unit and the 2d Battalion, 169th Infantry, reported their own losses as five killed and twenty-five wounded.
Despite further unsuccessful attempts to reopen the river crossing by the 1st Battalion, 239th Regiment, Adachi eventually decided on July 25 to dispatch the 41st Division south to reinforce the southern front. Following the fall of Afua, Hall directed Howe’s battalions to depart from their East Branch base and reinforce Cunningham’s South Force, successfully arriving at the new defensive line by July 23. With these reinforcements in place, Cunningham early in the afternoon of the same day decided to deploy Troops A and B to advance westward toward Troop C, while Howe’s 2nd Battalion pushed southeast to support the isolated troop. Despite the lack of coordination in the attack, infantrymen managed to infiltrate Troop C's perimeter from the northwest, aiding in repelling a fierce Japanese assault from the southwest, while the cavalry troops reclaimed Afua and established new defensive positions.
Despite an initial triumph, American efforts to advance on July 24 were thwarted by the resolute defense of the Japanese, who fiercely guarded all paths, trails, and ridges in the densely forested terrain northeast of the perimeter. However, on July 25, Companies E and B under Howe surprisingly made contact roughly 500 yards north of the besieged forces, encountering minimal resistance, which allowed the beleaguered Troop C to retreat. With Troop C relieved, Howe’s units continued their assault southward and westward toward the Afua-Palauru trail, driving the Japanese forces into the Torricelli Mountains. Nonetheless, a significant number of Japanese troops remained within a triangular area delineated by the sloping ground, Afua, and Company G's ridgeline position, persistently harassing Cunningham’s forces. Throughout the night, additional Japanese reinforcements, including the 66th Regiment, maneuvered behind Howe’s 2nd Battalion, securing control over trails leading southeast through dense jungle from the banana patch to a point on the Afua-Palauru trail near the 2nd Battalion's command post. Consequently, on July 26, Howe’s 1st Battalion was withdrawn toward the sloping ground, with the 2nd Battalion expanding its positions to the east to cover the vacated area. On July 27, the battalion launched a successful southward attack; however, menacing Japanese movements to the west compelled the American forces to withdraw, despite other units under Cunningham also repelling enemy advances. Subsequently, Cunningham reorganized his lines on July 28 to strengthen defenses, anticipating imminent large-scale Japanese assaults. Nonetheless, on July 29, the 1st Squadron and the 2nd Battalion renewed their offensive toward the south and west into the Triangle, yet this time Adachi’s determined defenders successfully rebuffed them.
Therefore, local patrol activity was the primary focus on July 30 and 31 while Cunningham devised plans for another offensive into the Triangle. Major combat activity revolved around the withdrawal of Company G, 127th Infantry, from its exposed outpost west of Afua. On the afternoon of the 29th the unit had been driven more than 400 yards east of its original position by Japanese attacks and had established new defenses on high ground about 300 yards west of Afua. On the 30th the company was surrounded and spent all day fighting off a series of small-scale attacks. The next morning it fought its way north to the dropping ground, where it arrived about 1330. Thence, it moved on to the Driniumor and joined the rest of the 2d Battalion, 127th Infantry, which had switched positions with the 3d Battalion.
During the period from 13 to 31 July, South Force had suffered almost 1,000 casualties, of which 260 had been incurred by the 112th Cavalry. For the understrength cavalry regiment, this was a casualty rate of over 17 percent. The 2d Battalion, 127th Infantry, had also lost heavily and was in need of rest, reorganization, and re-equipment--needs which had prompted General Cunningham to change the places of the 2d and 3d Battalions, 127th Infantry. South Force casualties were as follows: 106 killed, 386 wounded, 18 missing, and 426 evacuated as a result of disease and sickness. South Force estimated that it had killed over 700 Japanese.

With the capture of Guam, the Marianas campaign had finally come to an end. Yet it seemed apparent to the frontline commanders, the closer the island hopping got to the Japanese home islands, casualties were exponentially mounting. How much American blood was it going to take to end the Pacific War?

- 141 - Pacific War Podcast - Battle of Sansapor July 30 - August 5, 1944
30 jul· The Pacific War - week by week
Last time we spoke about invasion of Guam and Tinian. Japanese forces, led by General Obata on Guam and Colonel Ogata on Tinian, prepared defenses with trenches, pillboxes, and artillery. The Americans bombarded these defenses extensively. Despite resistance, they successfully landed on Guam and Tinian, securing beachheads. Intense fighting ensued, with Marines facing heavy casualties. Despite Japanese counterattacks, American forces gradually expanded their footholds, leading to the eventual containment of the Japanese on Orote Peninsula. The Japanese launched a fierce assault against Marine positions on Guam, engaging in close combat with heavy casualties on both sides. Despite initial success, the Japanese offensive was repelled by intense artillery and machine-gun fire, leaving the remaining enemy forces to defend Orote Peninsula. On Tinian, after extensive naval bombardment, Marines landed successfully, repelling Japanese counterattacks and establishing a beachhead. Despite heavy Japanese casualties, the Marines suffered relatively few losses, ultimately breaking the enemy's resistance.
This episode is the Battle of Sansapor

Following the successful capture of Noemfoor and Biak, the Allies possessed ample air and supply bases to advance to the Vogelkop Peninsula, fulfilling General MacArthur's aim of establishing a vital airbase supporting further operations northwestward, potentially towards Mindanao or via Halmahera. Initially considering Manokwari as a non-critical objective, MacArthur's plan centered on seizing Sorong and Waigeo Island for crucial supply and air bases in New Guinea. However, the rapid pace of Pacific theater operations raised doubts about the feasibility of bringing the Klamono oilfields into production before the war's end, prompting the cancellation of exploitation plans by the Joint Chiefs of Staff.
The Joint Chiefs assumed responsibility for the direction and coordination of oil rehabilitation projects in the Dutch East Indies and undertook necessary liaison with British and Dutch agencies. By mid-February 1943 they had decided that military units would at least start all oil rehabilitation and exploitation projects in the Indies, although the final development of the oil resources might be left to civilian agencies. MacArthur was instructed to plan the location and timing details of oil rehabilitation projects in the Indies, and, subject to the Joint Chiefs' approval, execute those plans. At the same time, the Joint Chiefs directed that the organization of special military petroleum production and refining units begin. The requisite troops, most of them US Army engineers and many especially recruited from civilian pursuits, soon began to assemble and train in California. Orders were also placed with manufacturers for the special production and refining equipment, which was sent to California as it was obtained. While these steps were being taken to coordinate oil rehabilitation projects, it had become obvious that in accordance with MacArthur's plans the first significant oil producing region that could be recaptured in the Netherlands East Indies would be the Klamono district on the Vogelkop Peninsula. The Klamono oil was especially valuable in that it could be used as fuel for naval vessels without refining beyond a little "topping" to remove excess naphtha. With limited effort, the wells could be expected to bring in some 16000 barrels of crude oil per day; with additional development, about 25000 barrels. Such production would presumably save the Allies considerable shipping space and time, for, instead of the long haul from United States ports, navy bunker fuel could be produced and topped as necessary much nearer to the scene of combat.
With the oilfields no longer a priority and aerial surveys indicating unsuitable conditions for airstrips on Waigeo, MacArthur opted for ground reconnaissance of the Mar-Sansapor area. This exploration revealed promising landing beaches and potential airfield sites, albeit requiring significant effort to develop. Consequently, MacArthur directed Alamo Force to secure the lightly-defended Sansapor-Mar area instead of Sorong-Waigeo, scheduling a landing for July 30. General Krueger tasked General Sibert’s 6th Division with Operation Typhoon, designating the 20th Regiment at Wakde-Sarmi as reserve and arranging relief by Major-General John Persons’ 31st Division.
Admiral Fechteler’s Task Force 77 had devised a strategy: to deploy Colonel Forbie Privett’s 1st Regiment, consisting of the 1st and 2nd Battalions, onto the Red Beaches northeast of Mar. Concurrently, Sibert’s 6th Cavalry Reconnaissance Troop was tasked with securing Middleburg Island. Following the landings, airfields were to be constructed at these sites. The subsequent phase involved Privett’s 3rd Battalion executing a shore-to-shore movement to establish a PT base on Sansapor’s Green Beach, scheduled for the day after the initial landings.
To set this plan in motion, the 31st Division commenced unloading operations at Maffin Bay on July 14 and successfully relieved Sibert’s units four days later. The two regimental combat teams of the 31st Division, the 155th and the 167th, which operated at Wakde-Sarmi had no previous combat experience but received much valuable training in a series of patrol actions, company-sized scouting missions, and battalion reconnaissances in force. General Persons wanted to mount an offensive to drive the Japanese from a main line of resistance which they had established in the low hills between Metimedan Creek and Sarmi, but the demands for labor at the Maffin Bay staging area and the necessity for committing many troops to the defense of that area made it impossible to assemble sufficient strength for such an attack. Then, by the time the 6th Division's requirements had been met, the 31st Division itself had to begin preparations for another operation. The 31st Division therefore had to confine itself principally to its patrolling missions, both west and east of the perimeter. Patrols east of the perimeter were sent out to hunt down stragglers from the Japanese Hollandia garrison, and most of them, comprising armed natives of the Wakde-Sarmi area, were led by a Dutch officer, 1st Lt. C.J. Sneeuwjagt. Meanwhile, work went on at the Maffin Bay staging area; and during the period July 18-August 31 a daily average of 2,500 tons of various supplies was unloaded at the bay. During the same period the 31st Division lost 39 men killed, 195 wounded, 34 injured, and 3 missing. The division in turn killed 294 Japanese, found 497 dead, and captured 14 others.
However, the deployment of the 6th Division faced delays due to heavy congestion in the Wakde-Sarmi area. It wasn’t until July 27 that Sibert’s combat units began departing from Maffin Bay towards Sansapor. Maintaining the element of surprise was paramount to General Krueger, hence no preliminary naval or air bombardment was conducted in the Sansapor-Mar area. Instead, General Kenney’s aircraft targeted Japanese bases at Manokwari, Sorong, and the Halmahera-Ceram-Ambon region.
To further deceive the Japanese, Fechteler’s convoy took a circuitous route to approach Sansapor, apparently arriving undetected around 05:00 on July 30. As anticipated, no opposition was encountered, and the first wave successfully landed at 07:01. While Privett’s troops swiftly unloaded on the mainland, one LST proceeded toward Middleburg Island. By 07:30, it began deploying the amtracs carrying the reinforced 6th Cavalry Reconnaissance Troop, which safely landed by 08:00. Encountering no resistance, the island was promptly secured, and the troop regrouped before setting sail for nearby Amsterdam Island, which was also secured unopposed by 11:30.
Upon returning to the mainland, following the incident where three unarmed Japanese were killed, Privett’s 2nd Battalion proceeded inland and eastward. They successfully established defenses along low hills roughly 800 yards from the shore. Meanwhile, the 1st Battalion encountered challenges navigating through dense jungle undergrowth. At 07:40, the 3rd Battalion landed and moved west along the beach to the Wewe River mouth, preparing for the next day's advance to Sansapor. By nightfall, all units were ashore, securing the desired beachhead perimeter. The following day, Privett’s 3rd Battalion embarked for Green Beach at Cape Sansapor, meeting no resistance upon landing at 08:44. They then proceeded south along the beach to secure Sansapor Plantation and Village by 10:00. While Cape Sansapor proved unsuitable for the planned PT boat base due to reef-bound shorelines and poor beaches, Amsterdam Island emerged as a promising alternative location. Subsequent operations in the Sansapor-Mar area involved patrolling to eliminate scattered Japanese groups, expanding the beachhead, and safeguarding airfield installations. A significant event occurred on August 3 when 92 sick or wounded Japanese and Formosan troops were captured at a Japanese hospital near Cape Opmarai. Concurrently, General Anami acknowledged the untenable positions on the northeastern Vogelkop and General Ikeda’s 35th Division abandoned Manokwari on July 16, embarking on a challenging overland march towards Sorong with limited supplies. Around the same time, General Teshima’s headquarters at Manokwari and other small garrisons in the region commenced an overland journey to Windehsi.
By August 15, as units of the 35th Division approached the Kor River, the 63rd Regiment moved into the vicinity, engaging in skirmishes with retreating Japanese forces. In these encounters, they eliminated 17 enemy combatants and captured 4. By August 31, the 63rd Regiment had further success, neutralizing 155 Japanese soldiers and capturing an additional 42, with minimal losses on their own side: 3 soldiers killed and 4 wounded. Similarly, patrols from the 1st Regiment on the western flank encountered retreating Japanese forces, resulting in the elimination of 197 enemies and the capture of 154, with only 4 soldiers wounded by the end of August. The total casualties for the Typhoon Task Force amounted to 14 killed, 35 wounded, and 9 injured, while they managed to account for 385 Japanese and Formosans killed and 215 captured. Ikeda’s division remnants reached Sorong on August 25 after enduring a grueling 40-day march. Additionally, construction of the Middleburg strip was successfully completed by August 14, and the Mar Drome was slated to be operational by September 3 to accommodate Kenney’s fighters and medium bombers.
Transitioning to Tinian, following the successful landing on July 24 and the subsequent destruction of the Japanese counterattacking force, General Schmidt's primary objectives for July 25 included landing the 2nd Marine Division and expanding the beachhead. While General Watson’s Marines disembarked swiftly, General Cates’ 4th Marine Division initiated their advance at 10:00. Colonel Jones’ 23rd Marines navigated through dense canefields and underbrush along the coast beyond the O-1 Line. Colonel Batchelder’s 25th Marines executed an enveloping maneuver against Mount Maga, securing its summit after intense combat supported by mortars and tanks. Colonel Hart’s 24th Marines swiftly moved south and eastward, reaching the O-2 Line.
Upon arrival, Colonel Wallace's 8th Marines assumed control of the far left flank and proceeded slowly through the rugged coastal terrain and dense undergrowth toward Ushi Point. Following the successful capture of a Japanese stronghold, the Marines advanced unopposed, advancing 200 yards past O-2 swiftly. However, the day brought hardship for the 14th Marines, facing heavy counter-battery fire resulting in the loss of 13 soldiers killed and 22 wounded. Admiral Mitscher's Task Force 58 conducted a reconnaissance-in-force of the western Carolines and launched a third raid on the Volcano-Bonin Islands to thwart enemy bomber interference, resulting in the destruction of five ships, damage to others, and the loss of 13 enemy planes for only 16 aircraft lost. The next day, Schmidt's undermanned divisions, later reinforced with 1782 replacements to fill Saipan-related gaps, commenced the advance to the O-3 Line. While the 23rd Marines steadily advanced with minimal resistance towards the vicinity of the O-4 Line, the bolstered 25th Marines cleared Mount Maga and, securing the summit of Mount Lasso, advanced into the O-4A Line virtually unchallenged. Meanwhile, the 8th Marines rapidly secured the Ushi Point flats and its airfield, Colonel Stuart's 2nd Marines swiftly advanced eastward, securing Asiga Point upon reaching the east coast by 12:30, and Colonel Riseley's 6th Marines, after landing, pushed southward to establish a line abreast of the 2nd Marines.
On July 27 and 28, encountering minimal opposition, the Marines advanced southward in a concerted effort, with riflemen in formation and skirmishers leading the way. The NTLF G-2 Lieutenant Colonel Thomas R. Yancey came to a conservative conclusion on July 27 that summarized not only that day's enemy situation but the entire operation's enemy situation as well: “Without saying so, he seemed to indicate the importance of all units conducting aggressive patrolling far to the front: To date there have been no indications that our front line units have encountered the 50th Infantry Regiment in force [since the first night's counterattacks]. It is believed that this unit is largely intact and it is known that they are well equipped and seasoned troops. They are capable of intervention at any time and may be expected to offer a strong opposition when encountered.” In the same report, Yancey noted that the "most likely enemy capability" was: "To fight a delaying action, withdrawing to, and organizing further defenses in, the high ground in the southeastern end of the island." Faced with this enigmatic enemy situation, General Schmidt formulated his scheme of maneuver and assigned his objectives on July 27 and 28 to facilitate an irregular "elbowing" advance. From the front lines held on the morning of July 27, Objective O-4 was near for the 4th Division, far for the 2nd Division; once Objective O-4 had been reached, the emphasis would shift--Objective O-5 would be near for the 2nd Division, far for the 4th Division. The Corps' attack on these two days, then, would find the 2nd Division carrying the ball on July 27, the 4th Division on the 28th. On the first day the 2nd Division would push forward at 07:30, the 4th Division at 10:00; on the second day the 4th Division would attack at 07:00, the 2nd Division at 10:00. Variations in these attack hours were consistent with plans to punch first with the left, then with the right. Principal advantage of this arrangement was that the bulk of the supporting fires could be allotted first to one division, then to the other. Not only did the 14th Corps Artillery mass its fires to support the main effort, but two 105mm howitzer battalions of the division executing the secondary attack were also made available to support the principal thrust in each case.
Despite the gradual progress made by Cates’ Marines as they secured key positions on higher terrain, they successfully reached the O-4 Line by the end of the first day. Simultaneously, Watson’s Marines made significant strides on more favorable terrain, aided by tanks, covering a distance of 4000 yards to also reach the O-4 Line. The following day, amidst worsening weather conditions, the 2nd and 6th Marines quickly moved forward to secure the O-5 Line. The weather at Tinian had been unpleasant. Nearly every day featured rain squalls, gusty winds, and ominous clouds. And yet, for Jig-Day and three days following, the seas remained calm enough for reasonably convenient shore activities. The "three days of good weather" that Admiral Hill had considered vital had already expired. On the afternoon of 28 July the weather got worse--much worse. This condition resulted from the effects of a typhoon that built up west of the Marianas and sent its swells and winds against Tinian's west coast. The seas surrounding Tinian changed to a dirty gray-blue as the winds mounted and the waves boiled over one another and grew into larger, uglier masses. Surf roaring against the tiny WHITE Beaches and their rocky flanking shelves forced temporary suspension, at 1800 on 28 July, of all unloading over the beaches.
On the left flank, after intense artillery bombardment, Cates’ Marines swiftly advanced to the O-5 Line, then, supported by naval forces, resumed their march to secure Gurguan Point and its airfield, advancing to the intermediate O-6A Line, with Jones’ 23rd Marines covering a total distance of 7300 yards. On July 29, with half of the island under control, Schmidt directed his forces to push beyond the O-6 Line. Accordingly, the 24th and 25th Marines advanced with minimal resistance and reached the O-6 Line. Although Watson’s Marines faced initially light opposition, resistance intensified as they crossed the O-6 Line. The 6th Marines managed to secure advantageous positions just shy of the intermediate O-7A Line, while the 2nd Marines encountered opposition around the Masalog Point hill, halting their progress. The next day, Cates’ Marines resumed their southward advance, encountering resistance from Japanese machine-gunners and riflemen entrenched in coastal caves.
While tanks engaged the enemy, the 24th and 25th Marines surged forward, effectively securing Tinian Town and its airfield, and eventually reaching the O-7 Line. On the right flank, Watson’s Marines also pressed southward, with the 2nd Marines swiftly securing Masalog Hill and advancing along the coast despite heavy machine-gun fire, reaching O-7, while the 6th Marines advanced against sporadic resistance, also reaching O-7. Additionally, the 8th Marines took position at the center of the corps’ line. With the capture of four-fifths of the island and over 3000 Japanese either killed or captured, Schmidt’s Marines successfully pushed the remaining Japanese forces under Colonel Ogata’s command into an unnamed ridge between Lalo and Marpo Points at Tinian's southern end.
On July 31, following a massive artillery, air, and naval barrage, the Marines launched another assault to the south. The 24th Marines made significant progress along the coast and on less steep cliffs, securing the road to the ridge top. The 23rd Marines faced stiffer resistance but advanced with remarkable discipline, aided by tanks, gaining high ground. On the right flank, the 2nd and 6th Marines advanced against light machine-gun and mortar fire, reaching the intermediate O-8A Line. In the center, the 8th Marines encountered stronger resistance but managed to establish a foothold on the zigzag road to the top. By nightfall, a 600-yard gap emerged between the 8th and 23rd Marines, which the Japanese could exploit.
At 23:00, a banzai charge was repelled; however, at 01:00 on August 1, a 150-man force blocked Wallace’s rear road and launched an attack. A counterattack force was quickly organized, driving back the enemy. Ogata's final banzai charge at 05:15 was directed at the left of Company E but failed to breach Marine defenses. Both Colonel Wallace and the enemy commander probably still Colonel Ogata had realized the tactical implications of the cliff-line penetration. Both knew that it provided a route over which thousands of Marines could move into the Japanese rear. The two commanders' reactions were classic. As soon as one of his battalions grasped a toe hold, Wallace exploited the success by committing his reserve there. The enemy commander, as soon as he received word of the penetration, ordered a counterattack to throw the Marines off the cliff and restore the position. Each selected a tactically sound course of action. Only one could be successful.
At dawn, as the Japanese began to withdraw, Cates’ Marines continued the attack southward, with the 24th Marines reaching the O-8 Line at Lalo Point, and the 23rd Marines, after encountering a sheer cliff, retracing their steps to reach the cliffline in front of O-8. On the right flank, the 8th Marines swiftly advanced to O-8A and moved alongside the 6th Marines toward the cliffs overlooking the water. Finally, the 2nd Marines secured the high ground to prevent enemy escape along the east coast. Despite not reaching Marpo Point, organized resistance crumbled, leading Schmidt to declare Tinian secure at 18:55.
Organized resistance had ceased. But on the early morning of August 2, an enemy force–estimated variously from 100 to 250–struck headlong into the command post of the 3rd Battalion, 6th Marines. Headquarters personnel, armed for the most part with carbines and pistols (although two automatic rifles were also used), considered the enemy group very well "organized." Initially, personnel of the aid station bore the brunt, but soon everyone in the headquarters group–clerks, communicators, corpsmen, assault engineers, mortarmen, and staff personnel–rallied behind their commanding officer, Lieutenant Colonel Easley, to defend themselves. The Japanese, carrying rifles, grenades, and machine guns, hurled themselves at the Marines with characteristic violence. As soon as one fell, another took his place. In search of substantial assistance, Captain John R. Steinstra, Headquarters Company commander, dashed to the nearby Company F, 6th Marines, acquired a medium tank and a rifle platoon, and led them back to the fight. Here was welcome reinforcement to the 3rd Battalion Headquarters Group, which had fought the enemy at close quarters for over two hours. The machine barged into the battle with guns blazing, and the tide turned. The battalion executive officer later stated that he considered the tank's appearance "vitally important" to the outcome. Those enemy soldiers who remained on their feet hastily departed the area. Daylight made results of the enemy effort visible: 119 Japanese bodies lay almost side by side in and around the 3rd Battalion command post. But the Marines had also taken casualties, one of the dead being Colonel Easley.
Nearly 400 Japanese perished in the week following the island's capture. From August 7 onward, the 8th Marines conducted cleanup operations on Tinian until January 1, 1945, eliminating an additional 542 Japanese at the cost of 38 killed and 125 wounded. Throughout the Battle of Tinian, a total of 5,745 Japanese were killed and 404 captured, while American losses amounted to 389 killed and 1,816 wounded. Similar to Saipan, around 4,000 civilians either took their own lives or were killed, but unlike Saipan, the majority—approximately 13,000 civilians—were interned.
On April 15, 1944, there were 16,029 civilians residing on Tinian, out of which 1,658, primarily consisting of women, children, and the elderly, were relocated to Japan prior to the American invasion. Approximately 2,610 civilians lost their lives during the conflict. Journalist Robert Sherrod observed that most casualties occurred due to direct combat, as the Americans heavily utilized artillery, aerial bombardment, and naval attacks, often forcing civilians to seek refuge alongside soldiers. Some perished from diseases, thirst, or hunger. Tragically, some were also victims of atrocities committed by Japanese soldiers, such as being tied together and attacked with grenades. Instances of mass suicide occurred, notably at the "Suicide Cliff," where parents threw their children off the 120-foot precipice, and some civilians were pushed by Japanese soldiers. According to a captured Japanese soldier, a large group willingly perished in caves at the military's behest. By August 1, only 2,468 civilians had been documented, but within three days, this number surged to 8,491. The 2nd Marine Division established a camp for civilians at Ushi Point Airfield, while the 4th Marine Division set up another at the ruins of Churo village, which became a permanent settlement for all displaced civilians. By October 15, Camp Churo housed 10,926 civilians, comprising mainly Japanese and Korean nationals, with nearly half being children under 15 years old. The military administration struggled to provide adequate care due to shortages of relief supplies. Seabees oversaw the construction of temporary shelters initially, which were later replaced by more durable structures using salvaged materials. The internees also supplemented their provisions by salvaging food and cultivating gardens, with Seabees stepping in to provide improvised diesel stoves as firewood became scarce. In late 1945, Admiral Spruance, who succeeded Nimitz as CINCPOA, ordered the repatriation of all Japanese and Korean civilians, a process completed by late 1946.
Shifting focus to Guam, by July 25, General Geiger's Marines had secured two beachhead areas, with General Turnage's 3rd Marine Division advancing on the Fonte Plateau and General Shepherd's brigade sealing off the Orote Peninsula. Despite a fierce enemy counterattack on both fronts, Japanese resistance was effectively shattered. On July 26, while mop-up operations continued in General Turnage's sector, General Shepherd's Marines prepared to assault Orote. Following coordinated air, naval, and artillery bombardment, the 4th Marines launched their attack at 07:00, making swift progress. However, the 22nd Marines faced delays due to enemy artillery fire, necessitating the 4th Marines to extend their line to cover the exposed flank. Although the mangrove swamp hindered Colonel Schneider's Marines, they successfully cleared the area by afternoon, establishing contact with Colonel Shapley's forces at RJ 15, albeit with a slight eastern bend in their line. Meanwhile, Shepherd's units encountered mines, pillboxes, and bunkers, halting their advance by nightfall.
On the morning of July 27th, the offensive recommenced, yet the 4th Marines encountered difficulties in penetrating the robust enemy defenses without tank support. However, once the mines were cleared, the Shermans neutralized enemy positions, enabling the Marines to take control of the ridge ahead, although they couldn't advance further through the coconut grove. Meanwhile, the 22nd Marines, moving alongside Shapley’s 3rd Battalion along the inland road, faced delays due to the swamp. They encountered numerous obstacles including pillboxes, trenches, dugouts, and mines near the old Marine Barracks. Remarkably, the determined enemy abandoned their fortified line around 5:00 PM after a substantial bombardment, allowing Schneider’s Marines to swiftly advance ahead of the 4th Marines and seize strategic terrain by nightfall.
Following another intense bombardment, Shepherd’s forces prepared to attack on July 28th. Despite Japanese resistance, Schneider’s tank-supported advance reached the O-4 Line by 10:05 AM, creating a significant gap between Marine regiments. Nonetheless, the 22nd Marines persisted, fighting through the Marine Barracks and halting just 100 yards east of Sumay. Meanwhile, the 4th Marines faced slow progress and fierce opposition, stopping within 150 yards of the airfield. On June 29th, Shepherd launched a final assault after yet another heavy barrage, with both regiments successfully advancing the entire length of the airstrip against minimal resistance, establishing a defensive line 150 yards beyond the strip by 2:00 PM.
As the 22nd Marines redirected their efforts to clean up the devastated Sumay area, effectively eliminating the last remaining enemy stronghold the next day, the 4th Marines continued their advance northward, with a combined tank and infantry patrol reaching the tip of the peninsula. With the peninsula now under control, the American flag was once again raised over the ruins of the Marine Barracks.General Shepherd proclaimed “On this hallowed ground, you officers and men of the 1st Marine Brigade have avenged the loss of our comrades who were overcome by the numerically superior enemy three days after Pearl Harbor.” Orote saw over 2500 Japanese casualties, while Marine losses amounted to 115 killed, 721 wounded, and 38 missing.
Moving northward, following a failed Japanese counterattack, Takashina’s forces were preparing to retreat further into the island's interior, but the Americans were relentless in their pursuit. After regrouping and subjecting the enemy to heavy bombardment, battalions from Turnage’s regiments launched an assault towards the Fonte Plateau on July 27, albeit encountering stubborn resistance from the still-active enemy. Meanwhile, Colonel Butler’s 3rd Battalion successfully advanced to the D-2 Line on the same day. Following successful defense against several small-scale enemy counterattacks overnight, Turnage initiated the main push towards the objective beachhead line on the morning of July 28.
The depleted 3rd Marines, with Colonel Craig’s 2nd Battalion attached, launched another assault, encountering minimal resistance and securing the D-3 Line by afternoon, thereby completely controlling the abandoned Fonte area. Further bolstered by the 3rd Battalion, 307th Regiment, the 9th Marines made progress in their attack towards the strategic Chachao-Alutom-Tenjo ridgeline, marking a significant initial victory. Simultaneously, the 2nd Battalion, 307th Regiment, supported by units from the 305th Regiment, advanced towards Mount Tenjo from the south.
Under the protective cover of artillery neutralization fire, Craig’s 3rd Battalion effectively demolished a concrete emplacement at the center of Mount Chachao’s summit and swiftly secured the beachhead line adjacent to Mount Alutom. Simultaneously, General Bruce’s infantry units swiftly captured Mount Tenjo, with Craig’s 1st Battalion joining them by day's end. The 21st Marines faced minimal resistance, eliminating remaining enemy pockets around the radio towers and reaching the designated beachhead line. Thus, Turnage’s attack objectives were achieved, extending the beachhead line across the entire front. Additionally, the 21st Marines overran the 29th Division command post near the Fonte River, resulting in Takashina's demise as he supervised his retreating units. Consequently, General Obata assumed direct command of the remaining forces, adhering to Takashina’s plan for a strategic withdrawal to Mount Santa Rosa, with delaying positions established at Finegayan and Mount Barrigada. The Japanese launched eleven localized counterattacks against Turnage’s beachhead line on July 29, all of which were successfully repelled, inflicting 800 casualties on the attackers. The 3rd Marine Division then focused on consolidation and reorganization for the remainder of the day while rear areas were cleared of enemy presence. In the meantime, as the 306th Regiment secured the unoccupied Mounts Alifan and Taene, Bruce had also dispatched several patrols to the southern end of the island since July 27, successfully discovering by the end of July that the sector had been completely abandoned.

- 140 - Pacific War Podcast - Invasions of Guam and Tinian July 23 -30, 1944
26 jul· The Pacific War - week by week
Last time we spoke about beginning of the bombing campaign against Japan. The Japanese 11th Army faced setbacks at Hengyang due to resilient Chinese defenses and supply shortages. Reinforced by General Xue Yue, Chinese forces launched effective counterattacks, regaining some territories before being pushed back. By July 20, the Japanese resumed their offensive but faced heavy resistance and were paused. American air raids on Japan and Manchuria intensified under General Arnold’s orders, despite logistical challenges. In Burma, Allied forces under General Stilwell made slow but steady advances, capturing strategic positions and repelling Japanese counterattacks. The Chindits, severely depleted, were eventually evacuated. In Yunnan, Chinese forces encircled and assaulted Japanese positions, achieving significant gains despite heavy resistance and logistical issues.

Today our week begins with the ongoings of Operation Forager. By late July, American plans for the invasions of Guam and Tinian were finalized. General Cates’ 4th Marine Division was assigned to land on Tinian’s White Beaches, while General Geiger’s 3rd Amphibious Corps planned two amphibious landings nearly seven miles apart to trap the Japanese in a double envelopment. General Obata, who had relocated his headquarters to Guam, commanded several troops on these islands. On Tinian, Colonel Ogata Keiji's forces included the 50th Regiment, the 1st Battalion of the 135th Regiment, the tank company of the 18th Regiment, and the 56th Naval Guard Unit, totaling 8,039 men. Similar to Saipan, he divided Tinian into three sectors, with most troops defending Tinian Town and Asiga Bay. The 1st Battalion of the 135th Regiment, supported by Ogata’s artillery, formed the Mobile Counterattack Force, ready to respond swiftly to landings. This left only Ogata’s 3rd Company to defend the northwest coast where the Americans planned to land.
Meanwhile, General Takashina’s 29th Division was assigned to Guam and reinforced by Major-General Shigematsu Kiyoshi’s 48th Independent Mixed Brigade and Colonel Kataoka Ichiro’s 10th Independent Mixed Regiment. Takashina’s units fortified the landward neck of the Orote Peninsula and established strong positions on the beaches of Agat, Asan, Tumon, and Agaña Bays. The main fortified area ran along the west coast from Tumon Bay to Facpi Point and included, of course, Orote Peninsula. Other fortified beaches, on the south and east coasts from Merizo to Pago Bay, had been abandoned before W Day, their defenders having moved to the north. Outside the main fortified area, the airfields were provided local defense by anti-aircraft and dual-purpose guns. The most notable and certainly the most effective fortifications on the island were constructed across the neck of Orote Peninsula, which contained a fairly elaborate system of trenches and foxholes arranged in depth, together with large numbers of pillboxes and heavy-caliber weapons. Outside of Orote, the prepared defenses were generally hastily constructed and often incomplete. The typical beach defense was arranged, from the seaward side, in four parallel lines: first were obstacles and mines on the fringing reef offshore; second came beach obstacles and tank traps; third were trenches, machine-gun positions, pillboxes, heavy weapons, artillery, and coast defense guns on the beaches or immediately inland; and, finally, came the machine-guns, heavy weapons, and artillery emplaced on the high ground inland. Insufficient advantage was taken of the high ground, and except on Orote little provision was made for defense in depth. Even as late as the five-week period of pre-invasion bombardment, the Japanese continued to work frantically on improving offshore obstacles and beach defenses, to the neglect of positions in the rear.They also had three tank companies in reserve to strike the beachhead alongside the infantry. Additionally, the 54th Naval Guard Unit, equipped with coastal defense and anti-aircraft guns, secured many positions with reinforced concrete.
The Japanese set up specific defense sectors on this island. Shigematsu’s brigade and Colonel Ohashi Hikoshiro’s 18th Regiment held the Asan Beaches and the Agaña and Tumon Bays. Colonel Suenaga Tsunetaro’s 38th Regiment defended the Agat Beaches, while Kataoka’s forces manned the southern defenses. Additionally, Takashina had a mobile reserve behind the Fonte Plateau, which included five infantry companies, one naval unit, and one tank company. Only Ohashi’s 2nd Battalion was positioned at Guam’s northern end, while Kataoka’s 1st Battalion was deployed to Rota Island. The Americans conducted the longest preliminary air and sea bombardment of the war against Guam, beginning on June 16 after the invasion of Saipan. This bombardment intensified after July 8, when American warships launched the greatest single naval bombardment program of the war, coordinated with Admiral Mitscher’s carrier aircraft. Over the next 13 days, a total of 836 rounds of 16-inch, 5422 of 14-inch, 3862 of 8-inch, 2430 of 6-inch, and 16214 of 5-inch shells were fired at Guam’s main defenses.
At the invasion of Roi-Namur Admiral Conolly had earned the sobriquet "Close-in Conolly" for his insistence that warships cruise close to shore when firing at land targets. At Guam, he reaffirmed his right to the title, but more important was the systematic procedure he introduced for coordinating naval gunfire and aerial bombardment and checking the results of each. A target board of six officers, representing the air, gunnery, and intelligence sections of the staff, was set up to assign primary missions for air strikes and naval gunfire and assess the damages daily before designating the next day's targets. Aerial photographs were taken each morning and on the basis of these damage was assessed and new targets were assigned. In these operations, the admiral's staff was aided by the presence aboard Appalachian of General Geiger who, as commanding general of the landing force, naturally had the greatest personal concern about the accuracy both of the bombardment and of the damage reports submitted afterward.
In the final three days before the landing, Mitscher’s planes conducted 1430 bombing sorties and 614 strafing attacks, dropping a total of 1131 tons of bombs, depth charges, and rockets, while losing only 16 aircraft. Despite the extensive bombardment, positions reinforced with coral and concrete remained in good condition. Anti-aircraft artillery and harbor installations suffered minimal damage, power installations in caves were unharmed, and communications were not interrupted.
The intensity of the attacks on the western defenses suggested a likely amphibious landing there, prompting Takashina to abandon the ineffective southern and northern defenses. Meanwhile, Conolly's vessels, carrying Geiger's Southern Landing Forces, departed Eniwetok for Guam between July 11 and 18, arriving successfully by July 21. Between July 14 and 17, three underwater demolition teams scouted the landing beaches, and under the protection of LCI gunboats, they removed 640 obstacles from the Northern Beaches and 300 from the Southern Beaches. On the morning of July 21, in excellent weather conditions, the Americans began a preliminary bombardment. Admirals Conolly and Reifsneider directed the shelling of Asan and Agat beaches, respectively, while Admiral Mitscher’s carrier aircraft bombed and strafed the fourteen miles of coastline from Agaña to Bangi Point. At 07:40, the assault waves crossed their departure lines under the cover of rocket fire from LCI gunboats. Eight minutes before landing, when the vehicles were 1200 yards from shore, Conolly's warships launched a final massive bombardment, and Mitscher’s fighters provided covering strafing attacks. These attacks were to be shifted inland as the troops approached the shore. Despite the intense bombardment from ships and aircraft, the Japanese managed to target the assault waves, destroying nine amtracs from the 3rd Marine Division. Nevertheless, the waves of vehicles advanced, and at 08:28, the first LVTs landed, two minutes ahead of schedule. Further south, shore fire was even heavier, hitting one LCI gunboat and destroying 13 amtracs. However, the landing formation held, and the troops landed on schedule.
Despite numerous concrete pillboxes still manned by the Japanese, both assault regiments advanced rapidly. Colonel Merlin Schneider’s 22nd Marines successfully captured Agat amid strong resistance but were eventually halted at a hill position northwest of the town. Meanwhile, Lieutenant-Colonel Alan Shapley’s 4th Marines cleared Bangi Point and Hill 40, setting up a roadblock supported by five tanks on Harmon Road. By the end of the day, General Shepherd had established a beachhead approximately 1300 to 2300 yards deep, at the cost of around 350 casualties and 24 lost LVTs.
At 08:30, the infantrymen of Lt. Col. Robert D. Adair’s 2nd Battalion were climbing down cargo nets from their transports into the bobbing landing craft that were to carry them to the edge of the reef. By 10:30 all boats were in position near the line of departure waiting for the signal to go in. For three and a half hours they circled impatiently. At last, at 14:05, came the message to proceed to the beach and assemble in an area 300 yards inland from Gaan Point. Unfortunately, no amphibian tractors were on hand to transport Adair's men over the reef and onto the shore line, and of course their LCVPs were too deep-drafted to negotiate either the reef or the shallow waters inland of it. Over the sides of their boats the men climbed, and waded the rest of the way in water at least waist deep. Some lucky few were able to pick up rides in Marine LVTs on the landward side of the reef, but most stumbled in over the rough coral bottom, cutting their shoes en route and occasionally falling into deep potholes. Luckily, no enemy fire impeded their progress, and except for the dousing they got and the exhaustion they suffered the troops of the 2nd Battalion, 305th Regiment completed their ship-to-shore movement without injury.To the north, Colonel Edward Craig’s 9th Marines advanced steadily against fairly heavy machine-gun and rifle fire, securing a beachhead about 1500 yards deep. Colonel Arthur Butler's 21st Marines, facing only moderate opposition but difficult terrain, cleared Asan Town and gained a foothold on the face of the Fonte Plateau.
On the left flank, Colonel William Hall’s 3rd Marines encountered the heaviest resistance from two complex cave defense systems on Chonito Cliff and Bundschu Ridge. Hall’s men cleared Chonito Cliff and Adelup Point after several costly assaults and heavy casualties, but progress against Bundschu Ridge was limited, resulting in a 200-yard-wide gap between the 3rd and 21st Marines. Nevertheless, General Turnage secured a beachhead approximately 1600 by 4000 yards and had landed all division infantry, artillery, and support units, at the cost of 105 killed, 536 wounded, and 56 missing.
Upon receiving the alert of enemy landings, Takashina promptly mobilized his reserve units to the Fonte Plateau in an attempt to contain Turnage’s Marines within their limited beachhead. Throughout the night, he initiated several fragmented counterattacks, all of which were easily thwarted, resulting in significant Japanese casualties. In the southern sector, the 4th and 22nd Marines heroically fended off numerous well-coordinated counterattacks, managing to destroy four enemy tanks and eliminate Colonel Suenaga along with his 38th Regiment. By July 22, Geiger’s forces began to expand their footholds on the beaches. In the northern front, Hall’s assault on the Bundschu Ridge faced formidable resistance. Despite some Marines reaching the ridge with support from 20mm and 40mm fire, they were compelled to withdraw due to intense mortar shelling. Unbeknownst to them, their relentless attack forced the Japanese to abandon the position, albeit at a significant cost to the 3rd Marines, which suffered up to 615 casualties and was unable to sustain the advance. Meanwhile, Butler’s 21st Marines encountered difficulty clearing the ravine separating them from the 3rd Marines, necessitating the deployment of their reserve 1st Battalion to support the depleted 2nd Battalion. On the right flank, Craig’s 9th Marines encountered minimal resistance as they swiftly secured the Piti Navy Yard, followed by the landing of the 3rd Battalion on Cabras Island after extensive naval and aerial bombardment. The only significant engagement during the night was a Japanese bayonet charge backed by mortar fire, which Butler’s 1st Battalion successfully repelled, inflicting heavy losses on the enemy.
To the south, following the night landings, the 305th Regiment underwent reorganization while Tanzola's 2nd Battalion relieved Shapley’s 2nd Battalion. Schneider’s 22nd Marines encountered moderate resistance as they moved northward after crossing the Ajuya River. Despite lacking tank support, they advanced until halting approximately 250 yards north of RJ 5. Simultaneously, Shapley’s 4th Marines launched an assault towards Mount Alifan's steep slopes, successfully neutralizing entrenched enemy positions using demolitions and grenades, though hindered by rugged terrain. Eventually, a platoon reached the summit, finding no enemy presence. Tanzola’s 1st and 3rd Battalions then advanced along Harmon Road towards the Maanot Pass, navigating eroded hills and dense vegetation to secure the O-a high ground line.
The 306th Infantry Regiment's landing on the White Beaches required the entire day because of communications problems and landing craft shortages. It was not until the next day that the 4th Marines was fully replaced by the 306th. 3rd Amphibious Corps Artillery was landing over White 1 at this same time, as was the 77th Division Artillery, leading to a great deal of congestion, especially when coupled with the landing of smaller units, supplies, and ammunition. Most artillery battalions were in-place by nightfall as was the 9th Defense Battalion deployed along the beaches. The defense battalions, besides providing air defense and direct fire support on ground targets, were positioned to engage any Japanese counter-landing attempts on the beachhead. The 77th Division, with the 305th on the right (center of the beachhead) and the 306th on the left, would secure the southern portion allowing the 4th Marines to move north with the 22nd Marines to seal off the neck of Orote Peninsula.
They continued their advance beyond Harmon Road and Maanot Pass, securing commanding positions overlooking Orote Peninsula. Meanwhile, Schneider’s 22nd Marines, initially advancing rapidly against scattered resistance, encountered intense enfilade fire from hills surrounded by rice paddies while attempting to maneuver across the neck of Orote Peninsula. This compelled them to withdraw approximately 400 yards to a line of hills south of Old Agat Road.
Further to the north, Hall’s 3rd Marines eventually discovered that the Bundschu Ridge had been deserted. However, following their clean-up operations, they were not in a condition to advance any further. Craig’s 3rd Battalion successfully secured Cabras Island and then relieved the 2nd Battalion on the mainland. Meanwhile, Butler’s 21st Marines faced challenges in bridging the gap with the 3rd Marines and encountered limited progress against well-fortified enemy pillboxes on the plateau’s slopes. Turnage initiated the first contact attempt with Shepherd’s brigade on July 24th, but the 30-man patrol was forced to retreat due to enemy fire. Despite Butler’s 2nd Battalion's efforts to close the gap by attacking up the ravine, they were repeatedly hindered by heavy machine-gun fire from caves on the cliff sides. Although both the 3rd and 9th Marines managed to enhance their positions, Turnage's casualties rose to 2034 since the initial landing.
Further south, Shepherd, in response to the formidable defense on the neck of the Orote Peninsula, instructed Schneider to advance the 1st and 3rd Battalions in company columns along the Agat-Sumay Road. The objective was to penetrate the enemy lines and seize the O-2 Line from the coast to Apra Harbor, while the 2nd Battalion shifted to occupy strategic high ground near Atantano from its position on the Old Agat Road. This maneuver not only flanked the Japanese strongholds guarding the rice paddies but also established a barrier across the neck of Orote, securing the beachhead line in front of the brigade.
Following an extensive air, artillery, and naval bombardment, Schneider's primary thrust along the Agat-Sumay Road encountered determined resistance but successfully advanced to the R-2 Line. The 1st Battalion then spread out to the right, while the 3rd Battalion veered further east across the hills, swiftly capturing the fortified positions around the rice paddies that had posed significant challenges the previous day. By nightfall, the 1st Battalion had reached the O-2 Line, but the 3rd Battalion halted 400 yards short of its target, prompting Shapley's 2nd Battalion to fill the breach between them. After repulsing a vigorous counterattack, the 2nd Battalion pushed forward with minimal opposition and secured Atantano. Consequently, by the end of July 24, Shepherd had firmly established his beachhead and contained the enemy on the Orote Peninsula, albeit with casualties totaling 200 killed, 748 wounded, and 97 missing. General Bruce, with the remainder of the 77th Division, assumed control of most of the beachhead perimeter, while Shepherd's Marines readied for the capture of Orote. Subsequently, after repelling several tank-led counterattacks resulting in the destruction of 12 Japanese tanks, they sealed off the peninsula entirely on July 25. By afternoon, approximately 2500 troops under Commander Tamai Asaichi were confined to the eight square miles of Orote Peninsula. Meanwhile, Turnage pressed his forces to secure the objective beachhead definitively.
Accordingly, the 9th Marines progressed southward along the Apra Harbor shoreline towards the Aguada River, reaching the midpoint before being compelled to retreat to the Laguas River due to Craig's stretched lines. Meanwhile, the 21st Marines faced formidable defenses at the Mount Chachao-Aluton-Tenjo complex, managing to establish defensive positions just shy of Mount Tenjo Road after slow progress. Simultaneously, the beleaguered 3rd Marines, with reinforcements from Craig's 2nd Battalion, launched a determined assault, overcoming moderate resistance and mortar fire to seize Mount Tenjo Road and gain a vantage point. Despite the extended frontline, troops stationed on the newly captured high ground could finally survey the terrain ahead by nightfall.
As Takashina consolidated his forces on the plateau, he prepared for a coordinated counterattack aimed at dividing and conquering the enemy. The 48th Independent Mixed Brigade planned to strike Turnage's left flank before pivoting northeast to target Hall's rear. Meanwhile, the 18th Regiment aimed to assault Butler's positions and advance toward the coast to establish a new defensive line, targeting the enemy's headquarters, artillery, and supply units. Additionally, elements of the 10th Independent Mixed Regiment were tasked with exploiting an 800-yard gap between the 9th and 21st Marines, protected only by the 3rd Reconnaissance Company.
In a desperate move following a failed attempt to evacuate by barge, Tamai opted for a nighttime banzai charge with his trapped 2500-strong force, seeking to break free from the Orote Peninsula and join Takashina's troops at Fonte. After dusk, the intermittent showers that had been falling all day became more frequent. A heavy downpour hampered organization of the brigade's defense for the night. On the other hand, the pitch blackness and the unpleasant weather aided the Japanese in making preparations for their supreme effort. Marines in the front lines could hear screaming, yelling, laughter, and the breaking of bottles as the Japanese made final arrangements. At times so much clamor could be heard that reports reached the command post that the assault had started. Afterwards someone aptly said that the confusion "sounded like New Year's Eve in the Zoo." While the enemy made ready and drank, Marine artillerymen laid down normal barrages along the swamp's edge and at all other points of possible penetration. Shortly before midnight the Japanese commanders felt that their men had reached the proper emotional state, and the assault began. Sake-crazed attackers swarmed from the cover of the mangroves in front of the 3rd Battalion, 22nd Marines. Led by flag-waving, sword-swinging officers, the enlisted men stumbled forward, carrying everything conceivable. Unsteady hands clutched pitchforks, sticks, ballbats, and pieces of broken bottles, together with the normal infantry weapons. The assault faced formidable resistance from Marine forces, particularly Shapley’s 1st Battalion, which alone accounted for 256 enemy casualties.
When the surging Japanese mass came within range, Marine forward observers and company commanders gave the order to commence firing. Brigade, 77th Division, and corps artillery, 37mm guns, 81mm and 60mm mortars, machine guns, rifles, and grenades saturated the entire area. At one time officers brought the fire of the Pack Howitzer Battalion, 22d Marines, to within 35 yards of 3/22's front lines in an at tempt to stop the swarming horde. One weapons company lieutenant reported: "Arms and legs flew like snowflakes. Japs ran amuck. They screamed in terror until they died." But in a powerful attack it is inevitable that some men will seep through the blocking fire. Company L, 3/22, received the brunt of the subsiding attack and repulsed it before too much damage could be done. Those Japanese who survived fled to the momentary safety of the swamp. But observers shifted the artillery fire and between midnight and 0200 some 26,000 shells took a heavy toll of the remaining peninsular defenders. On the right flank of the 22d Marines a second counterattack hit. The Island War describes the action quite vividly: “. . . At its height, flares revealed an out-of-this-world picture of Nipponese drunks reeling about in our forward positions, falling into foxholes, tossing aimless grenades here and there, yelling such English phrases as they had managed to pick up, and laughing crazily, to be exterminated in savage close-in fighting. Succeeding waves were caught in a deadly cross-fire. Not until dawn did this attack finally dwindle out, at which time more than four hundred bodies were counted in front of the position.” In contrast to the frenzied close quarter action in the 3/22 zone, the platoon from Company A (1/4) that filled the gap between the two regiments participated in a shooting gallery affair with the Japanese. Enemy troops made no attempt at a concerted attack, and the platoon plus artillery, without the loss of a single Marine, killed 256 Imperial soldiers. This fantastic figure was verified by officers from regiment the following morning.
Despite the intense machine-gun and artillery fire, some Japanese managed to infiltrate Marine positions, engaging in fierce hand-to-hand combat. However, by dawn, the Japanese offensive had been halted, with most remaining enemy forces eliminated, leaving Tamai with no option but to defend Orote Peninsula to the end. Meanwhile, Takashina's main assault, launched on July 26 at 04:00, faced initial success in overrunning Company B positions but was ultimately contained by the relentless machine-gun fire of the 1st Battalion.
Major Maruyama's men (2/18) advanced noisily, shouting, "Wake up American and die." The initial impetus of the assault passed completely over Company B in the center, previously reduced to about 50 men, and streamed through the gap down a draw toward the cliff. Despite the breakthrough, companies held the shoulders of the penetration and Lieutenant Colonel Williams ordered the units to refuse their flanks to the cliff. Company A on the left, commanded by Captain William G. Shoemaker, rallied in the face of the withering fire and overwhelming numbers. Shoemaker pulled back his right platoon to deny his flank to the enemy and to permit regrouping for a local counterattack. Company C (Captain Henry M. Helgren, Jr.) also successfully refused its flank to protect the position and immediately began firing into the onrushing Japanese. Tanks parked in the rear of the Marine positions took a great toll as the intruders surged through the widening gap. One report described the rush on the tanks as resembling a horde of ants. It went on to say of the Nipponese: “Savagely they swarmed upon the mechanized vehicles, oblivious of the vicious machine-gun fire, and frantically pounded, kicked, and beat against the turrets in an attempt to get the crew within. When this seemed futile they leaped to the ground and continued their wild rush down the draw to the rear areas. . .” Demolition charges were forgotten in the mad scramble to reach deeper into Marine-held territory. Machine gunners of 1/21 had a field day. Never had they seen such lucrative targets, but grenades and bayonets soon silenced the Marines as enemy soldiers overran the gun positions. Many of the Japanese were killed as they moved through the lines and into the ravine.
Although some of the infiltrating Japanese got down the cliff to attack the battalion command post and Butler’s mortar platoons, killing most of the mortarmen before being repelled by service troops, To the left, Craig’s tenacious 2nd Battalion, in its exposed position, received the brunt of Shigematsu’s attack, yet it managed to defeat seven determined counterattacks without losing any ground. Nonetheless, though they killed 950 Japanese, they suffered 50% casualties as well. Looking right, Ohashi’s 3rd Battalion hit Butler’s 3rd; and although two machine-guns were initially captured, their attack ended up being rapidly repelled. Consequently, the Japanese slid along the front and attacked down the vulnerable 800-yard gap, successfully defeating a strong roadblock to set up a dangerous line on the high ground behind Butler’s 3rd Battalion.
The lack of a swiftly organized regimental reserve line led to approximately 70 Japanese infiltrating into the Division Hospital area, where they were eventually repelled by a pioneer force. The first warning came about 6:30 when corpsmen reported that a number of enemy soldiers could be seen on the high ground to the right of the hospital. Division headquarters immediately ordered Lieutenant Colonel George O. Van Orden (Division Infantry Training Officer) to take command of two companies of pioneers standing by for just such an eventuality and clear the enemy from the hard-pressed area. At the hospital, doctors ordered patients to evacuate the tents and go to the beach. Onlookers saw a pathetic sight as half-clothed, bandaged men hobbled down the coast road helping the more seriously wounded to safety. 41 of the patients grabbed rifles, carbines, hand grenades, and whatever else they could find and joined the battle. The hospital doctors, corpsmen, and pajama-clad patients presented a rare sight as they formed a defensive line around the tents. It was a solid line, however, and one that held until the recently organized reinforcements arrived. Only one patient was wounded during the fighting, but one medical officer and one corpsman later died of wounds. The casualty list also included one medical officer, one dental officer, one Navy warrant officer, 12 corpsmen, and 16 Marines from the medical companies wounded in action. This does not include those casualties suffered by Van Orden's force. After cleaning out the assigned area, Van Orden proceeded up the Nidual River Valley in pursuit of the fleeing Japanese. The attack had pushed the enemy back to the hill at the head of the ravine by 11:00, but a request to send a Marine patrol to the ridge to determine the hostile strength was denied. Other plans had already been made for the assault of this dominating terrain. It was from this high ground that Major Yukioka's men paralyzed the operation of 3/21's CP and threatened the flank of both the 9th and 21st Marines.
While this action was taking place, the 12th Marines CP and several of its battalions were engaged in stopping the suicide squad attacks. In order to have these parties in position to make their foray in conjunction with the all-out offensive, enemy commanders had ordered the groups to infiltrate behind Marine lines on the night of 24-25 July. With typical Japanese patience, the raiders lay hidden in caves all day. As soon as darkness came on the night of 25-26 July they started firing random shots into the headquarters of the 12th Marines and began to move in small groups down the Asan Valley. A hand grenade duel went on during the early hours of darkness, but some of the intruders sought the safer confines of a cave not 20 feet from the headquarter's fire direction center. The artillerymen's perimeter defense held, and only one of the enemy succeeded in getting through to the guns. He was killed in the 3d Battalion's area before he could do any damage. In the five-hour long fighting around the regimental headquarters, 17 explosive-laden Japanese died. Most of them carried packs containing about 20 pounds of TNT with ready detonators, while others carried magnetic mines. With the coming of daylight, patrols went out to clean up any troops that might cause trouble later in the day. Men of the 12th Marines killed approximately 50-60 more enemy soldiers and drove the remainder into other areas where they were liquidated one by one.
Despite the initial success of Takashina’s well-coordinated counterattack, by noon, his forces had suffered defeat, marking the breaking of the backbone of Japanese resistance on Guam. Marine casualties were significant, with around 166 killed, 645 wounded, and 34 missing between July 25 and 27. Consequently, the 9th Marines retreated approximately 1500 yards to establish better defensive positions, and a battalion of Colonel Stephen Hamilton’s 307th Regiment was deployed near Piti Navy Yard. However, the focus now shifted to covering the invasion of Tinian. While naval guns had intermittently harassed Tinian since June 11, the preliminary bombardment of Saipan’s sister island commenced on June 20, with the first Army artillery battery targeting northern Tinian. By July 9, the 531st Field Artillery Battalion had fired a total of 7571 rounds. Following the fall of Saipan, the remaining 24th Corps Artillery and Marine howitzers intensified the bombardment, maintaining a continuous round-the-clock schedule and expending a total of 24,536 rounds on northern Tinian.
For the most part, 14th Corps Artillery confined its efforts to the area north of the line between Gurguan Point and Masalog Point, while aircraft restricted their efforts to the southern half of the island. Naval ships were assigned any targets on Tinian deemed unsuitable to either of the other two arms. Coordination of the three supporting arms was assigned to the corps artillery representative attached to General Schmidt's staff. In one instance, an artillery air observer discovered three 140-mm. coastal defense guns on Masalog Point that were within easy firing range of White Beaches 1 and 2, but were masked from field artillery. The battleship Colorado was called in and, with its main batteries adjusted by an airborne artillery observer, succeeded in neutralizing or destroying the enemy weapons. Because the spotting plane was not in direct radio contact with the ship, it was necessary for the plane to submit its spotting data to the artillery post by radio, whence they were relayed by telephone to General Schmidt's headquarters, and in turn by radio on another frequency to the firing ship. In spite of this somewhat complicated system of communications, the time lag was so slight as to be insignificant.
Meanwhile, starting from June 22, the P-47s belonging to the 318th Fighter Group maintained a relentless barrage on the airfields at Ushi, Gurguan Point, and just east of Tinian Town through constant strafing and bombing, further devastating the town to ruins. Beginning on July 15, naval gunfire operations were reinstated, with Admiral Hill’s cruisers and destroyers delivering destructive bombardment daily against Tinian’s harbor defenses. Then, on July 22, two P-47s dropped the first napalm bombs used in the Pacific war on Tinian, proving highly effective in incinerating canefields, underbrush, and enemy personnel located in open trenches and dugouts. The following day, Hill intensified preparatory fire with a formidable naval force comprising three battleships, two heavy cruisers, three light cruisers, and sixteen destroyers, positioned strategically to shell Tinian from all directions. However, there was no attempt to focus on the White Beaches to mislead the Japanese about the actual landing point. Throughout the rainy night, destroyers and cruisers maintained control over crucial road junctions while an UDT conducted a last-minute underwater reconnaissance, albeit unsuccessfully attempting to detonate recently discovered mines due to adverse weather conditions. At dawn on July 24, Hill’s transports carrying the 2nd and 4th Marine Divisions finally departed from Tanapag Harbor for the short journey to Tinian, successfully reaching their designated areas by 06:00. Simultaneously, the onslaught of artillery, air raids, and naval bombardment persisted over the Japanese defenses, intensifying into a full-scale onslaught by 07:00, with particular focus on the White Beaches. Additionally, efforts were made to neutralize mines on White 2, although these attempts proved futile.
As the assault waves took shape, General Watson’s Marines effectively executed the demonstration near Tinian Town without suffering any casualties. This demonstration effectively held the defenders in place, preventing them from deploying northward. However, a cleverly concealed Japanese battery managed to inflict significant damage on the battleship Colorado and the destroyer Norman Scott, resulting in the loss of 62 lives and 245 wounded before being neutralized. At 07:17, the initial landing wave crossed the designated line and began the 3000-yard journey to the beach, supported by intense pre-landing bombardment and rocket fire from LCI gunboats.
At about the same moment small-caliber fire--estimated variously as 50-caliber, 20mm and 40mm--began falling around the LST's. Its source could not be located because of the pall of smoke and dust that cloaked the island. Regarding this incident the logistics officer of the 2d Battalion, 23d Marines, aboard one of the LST's in the area, recalled: “The fire . . . wounded two or more Navy enlisted men of the crew of the vessel, and possibly a couple of Marines belonging to the landing team. . . . My recollection concerning the Marines who were wounded is hazy . . . the incident created a stir and speculation concerning the source of the fire, but everyone soon settled down to the business at hand.” Despite encountering the sporadic small-caliber fire, the LVTs successfully reached the narrow beaches by 07:50. Upon landing, Company E of the 24th Marines swiftly engaged and eliminated a small beach-defense unit on White 1, while the remainder of the battalion made landfall. On White 2, the 2nd and 3rd Battalions of the 25th Marines landed simultaneously but faced a delay in advancing due to the need for engineers to clear 100 horned mines that had destroyed three LVTs. Subsequently, Colonel Batchelder’s Companies G and I circumvented two enemy blockhouses and initiated an inland attack, while other units subdued strongpoints. However, the presence of additional mines and staunch resistance from caves and ravines prevented them from reaching their objective at the O-1 Line and Mount Maga. Meanwhile, Colonel Hart’s 1st and 2nd Battalions of the 24th Marines successfully advanced to the O-1 Line amid minimal opposition. Later in the day, reserve and artillery battalions were landed, along with Colonel Jones’ 23rd Marines, although their landing was delayed due to communication issues. This delay proved beneficial due to heavy congestion on White 2 at the time.
By nightfall, Colonel Wallace’s 1st Battalion, along with the 2nd and 4th Tank Battalions, under Hill's command, successfully disembarked 15614 men ashore. General Cates, anticipating Japanese counterattacks, directed his troops to halt at 16:30 to fortify defenses, achieving a beachhead spanning about 7000 yards. This came at a cost of 15 Marines killed and 225 wounded. Ogata, as expected by Cates, immediately ordered counterattacks with the 1st and 2nd Battalions of the 50th Regiment and mobilized the Mobile Counterattack Force. While Japanese probes commenced at 22:30, the major assaults, marked by fierce banzai charges, began after midnight.
The attack on the left came first and lasted longest. At 2:00, men of the 1st Battalion, 24th Marines, straining their eyes through the black moonless night, suddenly saw a compact group of Japanese a short 100 yards away. The Marines opened fire. The compact group became a screaming mass of attackers as the first Marine bullets and shells found targets. Now the shadows were alive with about 600 leaping Japanese naval troops, loaded with aggressive spirit, requiring no instructions to make their screaming charge. Marines called flares into action; the battlefield became light. Marines needed no orders either: the 37mm guns sprayed canister; machine guns cut into the enemy area with grazing fire; rifles pounded out at sighted or suspected targets; mortars crunched into the defilade areas; artillery crashed steadily behind the Japanese to shatter and destroy any reinforcement group. The tightly packed foe was a choice target for all these weapons, and hundreds of shells lashed his ranks. At no time did the enemy penetrate the 1st Battalion; but extremely heavy pressure against Company A, the unit that bore the brunt, caused the battalion commander to reinforce it with engineers, corpsmen, communicators, naval gunfire liaison and shore party personnel. The fight continued hot and heavy until about 0545, when dawn and the vigor of the enemy effort broke simultaneously. Medium tanks from Company B, 4th Tank Battalion, entered the fray at this time and stopped all further thrusts at the Marines' lines. Many Japanese, convinced that all was lost, committed suicide with grenades. While armored amphibians afloat fired on enemy groups hiding along the coast, Marines of the 1st Battalion, 24th Marines, mopped up the area to their front, an activity completed by 0700. They counted 476 Japanese bodies, most of them within 100 yards of Company A's lines. Although no figures are available for Marine casualties in this action, the battalion commander estimated that ". . . Company A was reduced to about 30 men with usable weapons before the enemy was repulsed."
Ogata’s infantrymen struck Cates’ center thirty minutes later, yet their efforts were thwarted by intense small-arms, mortar, and 37mm fire. Despite briefly breaching the line through weak points, they were ultimately defeated by rear elements after prolonged and heavy fighting.
This time, though many of the attackers fell forward of the lines, others penetrated a weak spot at the boundary between the two Marine regiments. About 200 Japanese poured through this spot before the flow could be stopped. After pausing in a swamp behind the lines, the enemy force speared out in two prongs: one straight into the beachhead toward U. S. artillery positions, the other turning west into the 25th Marines' rear areas. The latter group of Japanese attained first contact when they met a well-prepared support platoon from the 3d Battalion, 25th Marines. Positioned to contain just such a penetration as had occurred, the Marines quickly eliminated this Japanese threat, killing 91 in a brief, violent skirmish. The other prong pushed deep into the rear of the beachhead, finally reached the 75mm howitzer firing positions of the 2d Battalion, 14th Marines. Battery D, firing a mission for the 24th Marines, suddenly found itself beset from the front by many determined Japanese. Marines not actively engaged in servicing the howitzers rallied to the defense of their positions with small arms, while the remainder continued firing an artillery mission for the 24th Regiment. Later, as pressure mounted, all hands turned to the task of stopping the Japanese close at hand. At this juncture the .50-caliber machine guns of the other two batteries (E and F) of the battalion levelled a heavy volume of enfilading fire into the area forward of besieged Battery D. This fire, in the words of the battalion executive officer, "literally tore the Japanese . . . to pieces." To reinforce Battery D in its bitter fight, Company C, 8th Marines, arrived at 0445. But by then the situation was well in hand; the Japanese had faltered and stopped before the deluge of small-arms fire. Morning revealed about 100 dead Japanese in the area, while the artillerymen had lost but two of their number--both killed manning a .50-caliber machine gun with Battery D. The only Japanese penetration of the night had shattered itself against a prepared rear area. Up at the front, meanwhile, Marines of the 25th Regiment and the right (2d) battalion of the 24th Regiment, fought off a series of frontal rushes upon their positions. In each case the Japanese were stopped at the barbed wire forward of the Marines' lines. The all-night firing had taken a heavy toll of the Marines' ammunition stocks, however, and by shortly before daylight there was concern along the lines that another heavy attack might exhaust supplies. Dawn came first. Attached tanks moved up at once to range the area forward of the lines. They blasted points of resistance with their 75mm guns, killing or chasing such few Japanese as had survived the night melee. Nearly 500 Japanese were killed in the attacks against the center of the beachhead and in the skirmishes behind the lines following the penetration.
The third and last major enemy effort struck the extreme right (south) flank of the beachhead at 3:30. The 2d Battalion, 23d Marines, in position along the coast, bore the brunt of this thrust, although the 2d Battalion, 25th Marines, also figured prominently in the action. Moving north along the coastal road, the enemy force consisted of five or six light tanks (about half of those available to the Japanese at Tinian) with infantrymen riding and following on foot. First warning of the enemy move came when Marine listening posts stationed along the road a short distance forward of the lines reported enemy tanks rumbling in from the south. With the tanks an estimated 400 yards in front of the lines, Marine artillery opened up. The tanks came on. Ready for just this situation, U. S. ships began firing illuminating shells over the area, virtually turning night into day. Bazookas, 75mm half-tracks, and 37mm guns attached to three battalions now went into action. One of the 37mm platoons, positioned astride the coral road, leveled point-blank fires into the enemy armor. Even so, one fast-moving tank weathered a 37mm hit and drove through the front lines into rear areas before a Marine bazookaman finished it off. An officer present on the scene described the action as he saw it: “The three lead tanks broke through our wall of fire. One began to glow blood-red, turned crazily on its tracks, and careened into a ditch. A second, mortally wounded, turned its machine guns on its tormentors, firing into the ditches in a last desperate effort to fight its way free. One hundred yards more and it stopped dead in its tracks. The third tried frantically to turn and then retreat, but our men closed in, literally blasting it apart. . . . Bazookas knocked out the fourth tank with a direct hit which killed the driver. The rest of the crew piled out of the turret, screaming. The fifth tank, completely surrounded, attempted to flee. Bazookas made short work of it. Another hit set it afire, and its crew was cremated.” Thus, five tanks stood immobile on the field of battle. If a sixth accompanied this incursion, it escaped, since there was no trace of it the following morning when Marines moved through the area. Despite the fact that their armor was gone, enemy foot soldiers from the 1st and 2d Battalions, 50th Infantry, and the 1st Battalion, 135th Infantry, pressed toward the Marines. The fighting that ensued was close-in and savage, but the Japanese never cracked the tight defense. The few who seeped through the lines met a quick end at the hands of the 23d Marines' reserve (1st Battalion), positioned to provide depth in this precise area. The operations officer of the 2d Battalion, 23d Marines, described the weird termination of the Japanese activities: “. . . as it began to get light, Jap bodies began to fly ten to fifteen feet in the air in the area in front of our lines. . . . We knew that hand grenades did not have the power to blow a man's body that high and could not figure out what was happening. [Later] we moved out to mop up. . . . It turned out that about fifty percent of the dead Japs carried magnetic mines and had obviously been ordered to break through our lines and destroy the tanks in the rear of us. . . . The Japs who were wounded and unable to flee were placing the tank mines under their bodies and tapping the detonators.” Daylight revealed that the enemy had expended 267 men and five tanks (of 12 on the island) against the right flank of the beachhead with no success. By the end of the night's counterattacks, 1241 Japanese bodies lay scattered along Cates’ front, with the 1st Battalion, 135th Regiment virtually decimated, while Marine casualties numbered less than 100. Reflecting on the engagement, they later concluded: "It was there and then that [we] broke the Jap's back in the battle for Tinian". This assessment proved accurate, as Ogata’s forces began retreating towards the southern end of the island.

Similar to the experience invading Saipan, Guam and Tinian proved to be literal horror shows. The savagery of the Island hoping campaign had increased ten-fold. The Japanese hoped by inflicted as much pain as possible, the Americans might simply come to the peace table, but was there any real chance of that?

- 139 - Pacific War -First Bombing Campaign against Japan, July 16-23,1944
16 jul· The Pacific War - week by week
Last time we spoke about battle of Noemfoor. General MacArthur initiated a successful offensive on Noemfoor, with General Patrick's troops securing a beachhead. American forces encountered minimal resistance, occupying key positions. Despite initial skirmishes, American defenses held firm, inflicting heavy casualties. Meanwhile, in Aitape, ongoing clashes saw American forces repelling Japanese assaults. Despite setbacks, American defenses held, and preparations for a counteroffensive were underway. The Japanese breached American lines, occupying a 1300-yard gap but faced intense resistance. Martin ordered counterattacks and reorganization of forces along the X-ray River-Koronal Creek line. Despite some delays, American forces repelled Japanese assaults. In the Battle of Imphal, British-Indian troops repelled Japanese attacks, leading to their retreat. Operation Crimson saw successful naval and air assaults on Japanese positions, though with some setbacks. Admiral Somerville's diplomatic transfer followed, amidst reorganization of SEAC's higher officers due to internal conflicts.
This episode is the First Bombing Campaign against Japan

Our week's story first takes us over to the China Theater. Last time we spoke about China, the 11th Army's progress was halted at Hengyang in early July due to the resilient defense led by General Fang and a severe shortage of ammunition. General Yokoyama had to pause the offensive until his artillery unit could arrive to bolster the siege. Meanwhile, the 64th Division was dispatched to Changsha to relieve garrison duties. Despite these setbacks, the 13th Division secured Leiyang by July 4, and the 40th Division took control of Yongfeng on the same day, followed by Zhajiang on July 6. Although Hengyang was nearly surrounded, the Japanese forces had to entrench due to lack of supplies, which were delayed and harassed by General Chennault’s aircraft. Seizing this opportunity, General Xue Yue sent reinforcements and launched counterattacks against the besiegers. The 58th Army recaptured Liling on July 8 before being pushed back by the 27th Division two days later, while the Chinese forces began encircling Maoshizhen from the southwest by mid-July. By July 10, Yokoyama had received sufficient artillery and ammunition to resume the attack on Hengyang. Despite heavy air and artillery support, the 116th Division's assaults from the southwest failed to breach Fang’s defenses once again.
On July 15, the Japanese launched another assault, this time managing to displace the exhausted defenders from their outer positions and into the city itself. Two days later, the 13th Division also gained control of the airfield on the east bank of Hengyang and strategic points along the railway near the town. Despite these territorial gains, they were deemed insufficient considering the significant loss of life endured during the intense fighting of that week. Consequently, Yokoyama decided to pause the offensive once more on July 20, intending to concentrate his forces around Hengyang. The 40th and 58th Divisions were already en route to reinforce the front lines. However, during this period, two significant aerial operations occurred. Initially, following the bombing of Yawata, General Arnold ordered a subsequent night raid on Japan to underscore that Operation Matterhorn marked the beginning of a sustained bombing campaign, distinct from the isolated nature of the Doolittle raid. This was followed by a 100-plane attack on Manchuria and a 50-plane attack on Palembang.
Two days after the Yawata show General Arnold informed Wolfe that, despite the depleted fuel stocks in China, it was “essential” to increase pressure against Japan. Immediate objectives were: a major daylight attack on Anshan, small harassing raids against the home islands, and a strike against Palembang from Ceylon. When Arnold asked for an estimate of the command’s capabilities, Wolfe’s reply was none too hopeful. With low storage tanks at Chengdu (only 5000 gallons) he could not with his own resources build up for an all-out mission to Anshan before August 10. Ceylon fields would not be ready before July 15, and either the Palembang mission or the night raids would delay the Anshan attack. In spite of Wolfe’s cautious estimate, Arnold on June 27 issued a new target directive calling for a 15-plane night raid over Japan by July 10, a minimum of 100 planes against Anshan between by July 30, and a 50-plane mission to Palembang as soon as Ceylon airfields were ready. To meet this schedule, Wolfe was admonished to improve radically the operations of C-46s and B-29s on the Hump run. He outlined conditions necessary for fulfilling the directive: build-up of his B-29 force and a flat guarantee of ATC Hump tonnage. Even when it was decided that the command would get back its 1500 tons for July, Wolfe’s operational plan set up the Anshan mission for 50 to 60 B-29s, not 100 as Arnold wanted. Arnold received this plan on July 1. On the 4th General Wolfe was ordered to proceed immediately to Washington to take over an “important command assignment” and two days later he departed. Thus General Wolfe was in reality sacked, leaving General Saunders to assume temporary leadership.
Subsequently, on July 7, the requested night raid was carried out, involving 18 B-29s targeting the Sasebo Naval Base, with an additional six attacking other sites in Nagasaki, Omura, Yawata, and Tobata. Of the 24 bombers, 11 successfully bombed Sasebo using radar; individual planes struck Omura and Tobata, while the B-29 assigned to Yawata inadvertently bombed the secondary target at Laoyao harbor. Two other bombers, experiencing fuel-transfer issues, redirected to bomb Hankow, narrowly missing it by 20 miles. Despite witnessing explosions in all targeted areas, the damage inflicted on Japanese infrastructure was minimal. Only one bomber sustained damage, yet the successful attack heightened panic within the Home Islands.
After the disastrous loss of Saipan, it was clear to many of Japan's elite that the war was all but lost. Now Japan needed to make peace before the kokutai and perhaps even the Chrysanthemum Throne itself was destroyed. Tojo had been thoroughly demonized by the United States during the war, thus for the American people, Tojo was clearly the face of Japanese militarism. It was thus inconceivable that the United States would make peace with a government headed by Tojo. British historian H. P. Willmott noted that a major problem for the "doves" was that: "Tojo was an embodiment of 'mainstream opinion' within the nation, the armed services and particularly the Army. Tojo had powerful support, and by Japanese standards, he was not extreme." Tojo was more of a follower than a leader, and he represented the mainstream opinion of the Army. This meant his removal from office would not end the political ambitions of the Army who were still fanatically committed to victory or death. The jushin, elder statesmen, had advised Emperor Hirohito that Tojo needed to be sacked after Saipan and further advised against partial changes in the cabinet, demanding that the entire Tojo cabinet resign. Tojo, well aware of the efforts to bring him down, sought the public approval of the Emperor Hirohito, which was denied. Hirohito sent him a message to the effect that the man responsible for the disaster of Saipan was not worthy of his approval. Tojo then suggested reorganizing his cabinet to retain his position, but was rebuffed again. Hirohito said the entire cabinet simply had to go. Once it became clear that Tojo no longer held the support of the Emperor, his enemies had little trouble bringing down his government.The politically powerful Lord Privy Seal, Marquis Kōichi Kido spread the word that the Emperor no longer supported Tojo. Thus after the fall of Saipan, he was forced to resign on July 18, 1944.
Admiral Yonai Mitsumasa and General Koiso Kuniaki were appointed by Hirohito to form a new government, with Koiso ultimately becoming Prime Minister as Tojo's replacement. Meanwhile, Lieutenant-General Shimoyama Takuma’s 5th Air Army discovered Chennault’s aircraft and two Chinese squadrons concentrated at Guilin airfield on July 13. Seizing this opportunity, Shimoyama launched a daring raid that caught the Allies off guard, resulting in 80 aircraft destroyed on the ground. Despite this initial setback, Chennault’s P-51 Mustangs maintained superiority over the Zero, downing 88 Japanese aircraft in the following weeks at the cost of 27 Allied planes.
In Hengyang, preliminary artillery bombardment commenced on July 27 as Yokoyama’s forces prepared for their final offensive. Despite minor attacks in the subsequent days, little progress was made while the Japanese awaited the arrival of the 58th Division. Concurrently, the 27th and 34th Divisions advanced towards Lianhua to eliminate the 58th Army, resulting in heavy casualties and their subsequent withdrawal. By August 1, Yokoyama had amassed 110,000 troops around Hengyang, along with heavy artillery and mountain artillery pieces. In contrast, only 3,000 exhausted Chinese troops remained, valiantly resisting despite being cut off for over a month.
Returning to Matterhorn, Arnold insisted on a meticulously planned daylight attack involving 100 planes to be executed in July. Saunders managed to fit in the Anshan strike at the month's end by delaying Palembang until mid-August. The primary target was the Showa Steel Works at Anshan in Manchuria–specifically, the company’s Anshan Coke Plant, producing annually 3793000 metric tons of metallurgical coke, approximately ⅓ of the Empire’s total. About half of this was used by Showa’s own steel works, second in size only to Imperial’s, and the rest for various industrial purposes in Manchuria, Korea, and Japan. The secondary target was Qinhuangdao harbor whence coking coal from the great Kailan mines was exported to Japan. Tertiary target was the Taku port near Tianjin, which handled coal, iron ore, and pig iron. And as a last resort, bombers were to hit the railroad yards at Zhengxian, a possible bottleneck along a Japanese supply route. Aiming point at Anshan, as at Yawata, was to be a battery of coke ovens and again the bomb load was set at eight soo-pound GPs per plane.
Consequently, on July 25, 111 B-29s began staging to China, with 106 successfully arriving four days later. However, on July 29, only 72 B-29s managed to take off for the Anshan strike due to rain muddying the runway at Guanghan, preventing the 444th Group from launching. Mechanical issues further hindered eleven bombers from reaching Anshan, resulting in one bombing Qinhuangdao, two targeting Zhengxian, and four hitting other targets of opportunity. Despite these challenges, the sixty B-29s that reached Anshan maintained formation and bombed from altitudes close to the designated 25,000 feet under clear skies. However, the first wave mistakenly bombed a by-products plant adjacent to the aiming point, enveloping it in thick smoke. Anti-aircraft opposition was relatively light, with heavy flak damaging five B-29s and Japanese fighters downing only one bomber, whose crew escaped with the help of Chinese guerrillas. B-29 gunners claimed three probable hits and four damaged Japanese fighters. Chinese forces aided in rescuing a stranded bomber near Ankang. The plane was on the ground for five days while an engine, spare parts, tools, and mechanics came in by C-46 from Hsinching to effect an engine change and other repairs. Air cover was furnished by 14th Air Force fighters, who shot down a Lily bomber during a night attack. With full assistance from the Chinese and American garrisons at Ankang, the B-29 took off on August 3 and returned to Chiung-Lai. Another B-29 crash-landed in Vladivostok. Fortunately, on July 30, the wet strip at Kwanghan had dried sufficiently to launch 24 bombers of the 444th, albeit nearly five hours behind schedule. However, they were too late for Anshan, with 16 bombing the Taku port and three targeting Zhengxian instead. The day's efforts, though not flawlessly executed, brought encouragement to the command. American reconnaissance reported significant damage at Anshan, including hits and near misses on several coke-oven batteries, related installations, and the by-products plant. Taku and Zhengxian also showed substantial damage. The command gained valuable insights into conducting daylight missions, and despite the loss of five B-29s, it was deemed acceptable. That is all for now for the China theater as we now need to jump over to Burma.
Meanwhile, in north Burma, General Wessels decided to resume the offensive on July 12. Following a heavy air and artillery bombardment, a coordinated attack was launched, supported by 39 B-25s and the 88th Fighter Squadron, which successfully dropped 754 tons of bombs on Myitkyina. However, approximately 40% of the bombs landed among American troops north of Sitapur, resulting in casualties and confusion. Consequently, the coordinated attack stalled, with minimal gains by the 88th and 89th Regiments. Subsequently, Wessels' forces reverted to patient day-by-day advances, pushing back Japanese forces gradually. The tightening grip around Myitkyina was evident, with previously separated units now in close contact, preventing Japanese movement. Further south, General Stilwell directed the weary Chindit brigades to converge on Sahmaw and eliminate the 18th and 53rd Divisions. West African troops fought for control of Hill 60 to the north, while the depleted 111th Brigade engaged in battles at Taungni and the heavily fortified Point 2171. Stilwell also ordered the 300-man 77th Brigade towards Myitkyina, but Brigadier Calvert opted to cut off radio communications and withdraw his men to Kamaing, eventually evacuating them to India.
After returning back to Allied lines, Calvert and Lentaigne drove to Stilwell’s headquarters, where they found the general at a table with his son and Boatner. Then, speaking with the same sort of blunt honesty that Stilwell prided himself on, Calvert went into a long monologue explaining that despite their crippling losses and lack of heavy weapons, his men had sacrificed so much at Mogaung that now they had nothing left to give. To order the survivors into combat now was to pass nothing more than a death sentence. Stilwell seemed stunned at Calvert’s contained monologue. Then his shock turned to scathing anger towards his own staff. “Why wasn’t I told?’ he demanded. It quickly became obvious to Calvert that Stilwell had not realized the true tribulations his Chindits had gone through since the gliderborne invasion some months ago. As Calvert later wrote: “It became obvious from Stilwell’s repeated ‘Why wasn’t I told? Is this true?’ that his sycophantic staff had kept the true nature of the battle from him.” Overcome with the truth of it all, Stilwell apologized. “You and your boys have done a great job, I congratulate you.” Calvert was then allowed to evacuate his brigade. Their campaign was finally over.
The other brigades, nearing the edge of their endurance, didn’t experience the same fortune and had to persist in battling against the determined Japanese defenders. With morale faltering, Major Masters' only opportunity for success came through a bold flank attack on July 9 led by Company C of the 3/9th Gurkhas. As the Gurkhas fell back in disarray, savaged by machine-guns firing straight down the ridge, the surviving men scattered, diving into the jungle. Major Gerald Blaker moved on alone, firing his M1 carbine, yelling: “Come on, C Company!” Seeing him, the Japanese threw grenades. Braving the blasts despite an arm savaged by shrapnel, he charged the Japanese. At the last moment, the enemy gunners found the range and a volley of seven bullets plunged into Blaker who fell against a tree, bleeding profusely. He turned his head to call on his men: “Come on, C Company, I’m going to die. Take the position.” The Gurkhas surged forward, bayonets glinting in the dull light, crying: “Ayo Gurkhali, the Gurkhas have come!” Point 2171 then fell into Allied hands. 50 Japanese dead were counted on the summit. Major Gerald Blaker sacrificed his life during the assault and earned a posthumous Victoria Cross.
Shortly thereafter, the 14th Brigade relieved the exhausted 111th, which now counted only 119 fit men; and on July 17, Stilwell finally authorized the evacuation of Masters’ men. Thankfully, the seasoned 36th Division under Major-General Francis Festing would arrive in the frontline area to replace the depleted Chindits by the end of July, enabling General Lentaigne’s remaining forces to be brought back to India. The final to depart were the West Africans, who assisted the British in capturing Hill 60 on August 5, prompting the Japanese to withdraw towards Pinbow and Mawhun. Since the inception of Operation Thursday, the Chindits had suffered 5000 casualties, including killed, wounded, or missing, 3800 of them after Wingate’s demise. Their unconventional warfare had effectively diverted numerous potential reinforcements away from Imphal and Myitkyina; severed the 18th Division’s supply line, rendering its holding operation futile; and highlighted the importance of air supply as the sole means of sustenance during military campaigns, a lesson pivotal in the 14th Army’s subsequent offensives. Shifting focus to Yunnan, by the beginning of July, General Wei’s Y Force had successfully halted General Matsuyama’s counteroffensive in the Longling region.
In the interim, General Kawabe's Burma Area Army was formulating strategies to address the impending aftermath of Operation U-Go's unfavorable results. Following the completion of the 15th Army's retreat in central Burma, plans were set in motion for Operation Ban, a defensive maneuver aimed at countering anticipated Allied advancements along the Irrawaddy River. Concurrently, General Sakurai's 28th Army was organizing Operation Kan in anticipation of potential Allied incursions along the Bay of Bengal coastline. Additionally, General Honda's 33rd Army initiated preparations for Operation Dan, a synchronized offensive designed to repel the invading Chinese forces eastward across the Nujiang River and deep into Yunnan, thus thwarting the establishment of a land route between India and China by the Allies. Consequently, the 2nd Division under Lieutenant-General Okazaki Seisaburo was reassigned to the 33rd Army on July 19 to partake in the offensive, while Matsuyama's 56th Division was tasked with maintaining defensive positions in Yunnan. The 18th and 53rd Divisions were directed to safeguard the western flank against potential assaults originating from Myitkyina. Subsequently, Matsuyama opted to relocate his primary force from Longling to Mangshi, where he planned to rendezvous with Okazaki at a later date. To facilitate this relocation, Colonel Matsui's task force was dispatched on July 5 to dislodge the 76th Division from Mukang. Following a stealthy infiltration behind enemy lines on July 7, Matsui launched a surprise attack the following day, compelling the Chinese forces to retreat. With the route to Mangshi cleared, the 56th Division vacated Longling and began regrouping in the Mangshi vicinity, leaving a modest garrison of 2500 men to secure Longling. Throughout July, the city faced intense aerial and artillery bombardments, culminating in the capture of East Hill by the 87th Division on July 17.
Fortunately, Y Force's efforts were now focused on the previously bypassed blocks at Tengchong, Lameng, and Pingda, as the Chinese prioritized securing the flow of supplies to the front lines. At Tengchong, Colonel Kurashige was compelled to abandon Feifeng Hill after his 3rd Battalion departed to join Matsui’s task force, leaving him with just 2025 men. Facing him, Lieutenant-General Huo Kuizhang’s five divisions spread out around Tengchong, occupying the surrounding heights. Despite attempts at medium-level bombing causing severe damage to the residential area, it only resulted in rubble piling around Japanese positions. Thus, entrenched in their dugouts, the Japanese remained steadfast and successfully repelled Chinese attacks, with the Chinese managing to take Kaoliang Hill only by July 9th. Meanwhile, from the south, the 2nd Reserve Division severed Tengchong from Longling and initiated unsuccessful assaults against Laifeng Hill. By mid-July, with the city completely encircled, Huo was poised to launch a coordinated assault, but heavy rains delayed the operation. Concurrently, with the arrival of the 8th Army at Lameng, General Song aimed to continue his attacks against Major Kanemitsu’s garrison. Following a night-long artillery bombardment, the 1st and 39th Divisions fiercely assaulted Japanese positions on July 5th, successfully overrunning some of them and destroying Kanemitsu’s main water reservoir. However, despite ammunition shortages, Japanese counterattacks pushed them back to their original positions by nightfall. In the second week of July, Song deployed the 82nd and 103rd Divisions for an attack against Kanemitsu’s southwest defenses, initially achieving success but ultimately being repelled by Japanese counterattacks.
In the meantime, the Pingda garrison, devastated by cholera, was reaching its breaking point. Consequently, the Matsui Force was dispatched to provide relief on July 11, successfully reaching their designated gathering point northwest of Pingda after a challenging two-day march. On July 13, Matsui's initial assaults only secured the forward positions of the 226th Regiment; however, the following day, they managed to breach the Chinese defenses, delivering much-needed supplies to the Pingda Garrison and evacuating its sick patients. Having performed its mission, the Matsui Task Force started its return trip on the morning of 15 July. The following evening, an enemy group was discovered near Chungchai and the Task Force prepared to attack. Just before the actual launching of the attack, Col. Matsui received a message from division headquarters stating that, "A powerful enemy force is advancing toward Mangshih. The Matsui Force will return as soon as possible."
To the north, Song opted to halt the sporadic attacks and initiated a synchronized assault with his four divisions on July 23. Backed by intense artillery fire, the Chinese exerted significant pressure, eventually overrunning the Hondo Position by the end of July. Only the timely intervention of Japanese fighters halted the offensive. Further north, following the subsiding of the storms and a heavy air bombardment, Huo finally launched a general offensive on July 26, supported by artillery and mortars. Moving swiftly and with strength, the Chinese successfully demolished all fortifications on Laifeng Hill, compelling the Japanese, grappling with ammunition shortages and heavy casualties, to abandon their other outposts in the vicinity.
The Chinese attack that followed revealed that previous experiences with Japanese positions had not been wasted. The Chinese infantry moved off quickly, on time, and as whole regiments rather than squads committed piecemeal. Mortar and artillery fire was brought down speedily on suspected Japanese positions, and the infantry took full advantage of it by advancing again the minute it lifted. Having taken one pillbox, the Chinese infantry kept right on going rather than stopping to loot and rest. At nightfall they were on top of the mountain and had taken a fortified temple on the summit. After mopping up the next day, the Chinese tallied about 400 Japanese dead. They themselves had lost 1200. Nevertheless, the speedy capture of Laifeng Hill was a brilliant feat of arms and dramatic evidence of the capabilities of Chinese troops when they applied proper tactics While the simultaneous attack on the southeast wall of Tengchong did not breach the massive wall, the Chinese now held a solid position in the sparse cluster of mud huts just outside the wall. Yet that will be all for today for the Burma-Yunnan front as we now are heading over to the Marianas.
As we remember, Admiral Spruance devised a plan to initiate the invasions of Guam and Tinian following the capture of Saipan. Tinian's strategic significance stemmed from its close proximity to Saipan and its relatively flat terrain, making it more suitable for bomber airfields compared to its mountainous counterpart. However, its natural features also posed challenges for a seaside landing, with most of its coastline characterized by steep cliffs. Consequently, the American forces had limited options for landing: the well-defended beaches of Tinian Town, particularly the northeast Yellow Beach at Asiga Bay, or the less fortified but narrow White Beaches on the northwest coast. However, the latter option risked congestion and immobility due to the confined space. After assessing the landing beaches firsthand, they opted for the latter, anticipating lower resistance. General Smith's Northern Landing Forces were tasked with this operation, although there were some changes in the chain of command. Smith was appointed commander of Fleet Marine Force, Pacific, overseeing all Marine Corps combat units in the region. General Schmidt assumed command of the 5th Amphibious Corps and the Northern Landing Forces, while Major-General Clifton Cates replaced him as commander of the 4th Marine Division. Additionally, Admiral Hill assumed command of a reorganized Northern Attack Force for the amphibious assault.
The strategy outlined was for Cates’ 24th and 25th Marines to land on the White Beaches on July 24, securing a beachhead line encompassing Faibus San Hilo Point, Mount Lasso, and Asiga Point. This offensive would receive heavy artillery support from Saipan, as well as backing from carrier-based aircraft, Aslito airfield-based planes, and naval gunfire. One of the main justifications for the final decision to land over the unlikely beaches on the northwestern shore of the island was the feasibility of full exploitation of artillery firing from Saipan. Consequently, all of the field pieces in the area except for the four battalions of 75-mm. pack howitzers were turned over to 14th Corps Artillery during the preliminary and landing phase. General Harper arranged his 13 battalions, totaling 156 guns and howitzers, into three groupments, all emplaced on southern Saipan. Groupment A, commanded by Col. Raphael Griffin, USMC, consisted of five 105-mm. battalions, two each from the Marine divisions and one from V Amphibious Corps. It was to reinforce the fires of the 75-mm. pack howitzers and be ready to move to Tinian on order. Groupment B, under the 27th Division's artillery commander, General Kernan, was made up of all of that division's organic artillery except the 106th Field Artillery Battalion. It was to reinforce the fires of Groupment A and also to be ready to displace to Tinian. Groupment C, commanded by General Harper himself, contained all the howitzers and guns of 24th Corps Artillery plus the 106th Field Artillery Battalion. It was to support the attack with counterbattery, neutralization, and harassing fire before the day of the landing, deliver a half-hour preparation on the landing beaches immediately before the scheduled touchdown, and execute long-range counterbattery, harassing, and interdiction fire.
Concurrently, General Watson’s 2nd Marine Division would stage a feint near Tinian Town before landing behind the main assault force post-beachhead establishment. Meanwhile, General Griner’s 27th Division would remain on standby in corps reserve, ready to embark on landing craft at short notice. A notable logistical innovation for Tinian involved a dual shuttle system to prevent congestion. Loaded trucks and Athey trailers shuttled between Saipan's base supply dumps and Tinian's division supply depots, while amphibious vehicles directly transported supplies from ship to shore to division dumps, aiming to minimize beachside handling of supplies. Additionally, General Geiger’s 3rd Amphibious Corps, comprising the 3rd Marine Division and the 1st Provisional Marine Brigade, assisted by Admiral Conolly’s Southern Attack Force, were tasked with capturing Guam. Due to formidable coastal defenses, Geiger's plan necessitated landings north and south of Apra Harbor on July 21, bypassing the heavily fortified Orote Peninsula.
General Turnage's 3rd Marine Division was tasked with landing on the shores between Adelup Point and the Tatgua River mouth, proceeding southward to occupy the eastern area of Apra Harbor. Simultaneously, General Shepherd's 1st Provisional Marine Brigade was to land between Agat village and Bangi Point, then pivot northward towards the base of the Orote Peninsula. The establishment of a secure beachhead line from Adelup Point to Facpi Point was crucial before Geiger's forces could launch their assault on Orote Peninsula and subsequently secure the rest of the island. With the 27th Division committed elsewhere, Major-General Andrew Bruce's 77th Division, slated to assemble at Eniwetok by July 18, was designated as the new reserve under Geiger's command. The 305th Regiment was assigned to land behind Shepherd's Marines to reinforce the beachhead line. To optimize support for the troops, Conolly divided his Southern Attack Force into two: his Northern Attack Group, backing the 3rd Marine Division's landing, and Rear-Admiral Lawrence Reifsnider's Southern Attack Group, aiding the 1st Provisional Brigade's landing. Coordination of pre-landing bombardments was planned between Conolly's ships and aircraft, synchronized with scheduled strikes by aircraft from Admiral Mitscher's Task Force 58.

The time had finally come for the Japanese home islands to be subjected to the horrors of modern bombing campaigns. It would begin gradually, but would escalate to a literal horror show that starved the population of Japan into submission. Meanwhile Hideki Tojo was finally sacked, though by no means was he gone.

- 138 - Pacific War - The Battle of Noemfoor, July 9-16,1944
9 jul· The Pacific War - week by week
Last time we spoke about the fall of Saipan. General Smith's coordinated attacks on June 27th led to significant progress, with the 4th Marine Division notably advancing. The 27th Division encountered resistance, and casualties rose. By early July, Americans gained ground, pushing toward Marpi Point. Japanese resistance remained fierce, but American forces steadily advanced, capturing strategic positions. The assault on Petosukara was swiftly countered, but intense action unfolded in the Makunsha region. The 3rd Battalion, 24th Marines faced a fierce enemy thrust, with over 200 attackers killed. Facing defeat, General Saito ordered a suicidal assault, resulting in a chaotic and desperate charge. Despite heavy losses, American forces repelled the onslaught. The battle lasted until midday on July 7, with sporadic skirmishes continuing. Efforts to persuade cave occupants to surrender intensified, yet many civilians chose mass suicide. Saipan was declared secured after extensive casualties on both sides.
This episode is the battle of Noemfoor

General MacArthur unleashed a new offensive, seeing General Patrick’s troops successfully landed on Noemfoor with little opposition, securing a beachhead. While the 3rd Battalion, 503rd Parachute Regiment was being airdropped on July 4, Colonel Sandlin’s 3rd Battalion continued eastward through scattered minefields toward Kornasoren Drome, meeting no resistance. Simultaneously, the 1st Battalion crossed the Kamiri River and occupied Kamiri village without encountering any opposition. Moving out of Kamiri, the American forces followed a southeastern road to a sizable Japanese garden area, where they faced resistance on Hill 201.
The Japanese garden area was about 600 yards long, east and west, and 350 yards across, north to south. The ground was devoid of large trees except for a few atop Hill 201, but thick, secondary jungle growth covered the eastern and southern slopes of the hill, while the rest of the garden area was overgrown with partially cultivated papaya, taro, and cassava, all averaging about eight feet in height. The trail from Kamiri village passed over the southern slope of Hill 201, and 300 yards away, near the eastern edge of the gardens, joined the main road from Kamiri Drome to Namber Drome, located about six miles to the south. Another trail ran along the eastern side of the hill, branching to the north and northwest at the northeastern corner of the low terrain feature.
To counter this, a double envelopment tactic was initiated, with Company C seizing Hill 180 to the north while Company B pushed the Japanese southeast over Mission Hill, a lower terrain feature situated southeast of Hill 201. By 15:15, the battalion secured the ground on both flanks of Hill 201 and consolidated around the hilltop for the night, establishing a tight defensive perimeter. At 05:20 on July 5, the Japanese launched an attack along the southern and southeastern sides of the perimeter with mortar support. The American forces responded with a deadly barrage of mortar and artillery fire, driving the enemy back and neutralizing their machine-gun positions. Some Japanese managed to get through the mortar and artillery barrages and continued up the sides of the trail from the south through fire from Company D's machine guns. The enemy found cover behind a low, 150-yard-long log fence which led from the southeast toward the center of the 1st Battalion's defenses. While the fence afforded some protection, the attacking infantrymen were silhouetted as they tried to clamber over the top. The main body of the attacking force therefore kept down behind the fence, trying to crawl along it to the top of the hill. Advancing cautiously, the attackers encountered sustained machine-gun and rifle fire from the defenders atop the hill, as the fence did not extend beyond the outer defenses of the 1st Battalion.
The assault quickly deteriorated into a sequence of small suicide charges carried out by groups of three to six Japanese soldiers. The 1st Battalion now sent patrols out over the battlefield. From prisoners it was determined that the attacking force had consisted of 350 to 400 men--the 10th and 12th Companies, 219th Infantry, reinforced by approximately 150 armed Formosan laborers. During the morning over 200 dead Japanese were counted around the 1st Battalion's perimeter, and the number of enemy dead found or enemy wounded captured on subsequent days along trails leading south from the hill indicated that virtually the entire original attacking force had been annihilated.
By 06:30, the skirmish had concluded, with over 200 Japanese casualties tallied. Following this engagement, operations on Noemfoor transitioned into a series of patrol activities as Allied forces extended their dominance over the island and rapidly expanded the airfield facilities. On the morning of July 6, Sandlin’s 2nd Battalion executed an amphibious landing on the deserted Namber Drome following a brief naval bombardment. By July 10, intensive patrolling had only encountered small Japanese groups, leading Patrick to conclude that no significant organized enemy presence remained on Noemfoor. To eradicate the remaining opposition, the 503rd Parachute Regiment was dispatched to the island's southern sector while the 158th addressed the northern half. By the end of August, Sandlin’s efforts had resulted in the death of 611 Japanese soldiers, the capture of 179, the loss of 6 American lives with 41 wounded, and the liberation of 209 slave laborers.
The Japanese had never brought the Melanesians of Noemfoor entirely under their control, for the natives had either offered a passive resistance or had faded into the interior to live off the land. A few were impressed into service by the Japanese, while others who were captured but still refused to cooperate were executed. The natives greeted the Allied landings with great enthusiasm and came out of hideaways in the hills carrying Dutch flags which they had concealed from the Japanese. Under the direction of the Netherlands Indies Civil Administration, the natives were gradually resettled in their old villages. Late in July the village chiefs gathered in formal council and officially declared war on the Japanese. Thereafter, native cooperation increased. Up to August 31 the natives had captured and brought to Allied outposts more than 50 Japanese and had killed another 50. One tale of horror concerns the Javanese on Noemfoor. According to information gathered by the NICA Detachment, over 3000 Indonesians were shipped to Noemfoor in late 1943, mostly from Soerabaja and other large cities on Java. The shipment included many women and children. The Japanese, without regard to age or sex, put the Javanese to work constructing roads and airfields almost entirely by hand. Little or no clothing, shoes, bedding, or shelter was provided, and the Javanese had to supplement their very inadequate allowance of rations by shifting for themselves. Driven by hunger, many attempted to steal Japanese rations but for their pains were beheaded or hung by their hands or feet until dead. Starvation and disease took a steadily increasing toll. The dead were periodically collected for mass burial, and survivors alleged that many of the sick were buried alive. It was considered probable that not more than 10 or 15 Javanese were killed accidentally by Allied forces. Yet only 403 of the 3000-odd brought from Java were found alive on Noemfoor by August 31.
Meanwhile, Colonel Jones pursued the remnants of Colonel Shimizu’s Noemfoor Detachment to Hill 670 in the south. From July 13 to 16, both sides engaged in fierce combat for control of the hill, with the Japanese ultimately managing to evade capture. Contact was reestablished on July 23 near Inasi, but Shimizu eluded capture once more. The primary Japanese force was finally located on August 10 near Hill 380, prompting Jones’ 1st and 3rd Battalions to converge in an attempt to trap the enemy. However, on August 15, Shimizu once again evaded capture, slipping away towards Pakriki.
Although the Japanese forces were either captured or eliminated by August 17, Shimizu evaded capture or death and remained at large by the operation's conclusion. Jones' forces endured 57 fatalities and 302 injuries, but managed to neutralize over 1100 Japanese soldiers and apprehend approximately 560 individuals, while liberating an additional 194 enslaved laborers. This brings the total casualties for the Battle of Noemfoor to 1730 Japanese casualties, with 740 taken prisoner, and 63 American fatalities, 343 wounded, and 3 missing, alongside the liberation of 403 slave laborers. Transitioning to the developments on the Aitape front post-Operation Persecution, significant changes occurred under General Gill's command starting May 4. The defensive setup in the Aitape region was revamped, and Colonel Howe's 127th Regiment bolstered its eastern positions, with the Nyaparake Force extending patrols to the Danmap River. However, General Nakai's advance forces arrived in early May. Shortly after 2:00am on 14 May, after a short preparation by grenades, light mortars, and light machine guns, 100 to 200 Japanese of the 78th Infantry, 20th Division, attacked from the east against the coastal sector of the perimeter. This assault was broken up by rifle and automatic weapons fire and by lobbing mortar shells to the rear of the advancing enemy group. The Japanese disappeared into the jungle south of the narrow beach. For the next hour Captain Fulmer's mortars placed harassing fire into suspected enemy assembly points east of the small stream. Meanwhile, the eight-man outpost reported that many small parties of Japanese were moving up the beach within 300 yards of the main perimeter and then slipping southward into the jungle. Such maneuvers seemed to presage another attack. The second assault came about 0330, this time against the eastern and southeastern third of the defenses. The Japanese were again beaten back by small arms and mortar fire, but at 5:00am they made a final effort which covered the entire eastern half of the perimeter. This last attack was quickly broken up and the Japanese quieted down. About 7:30am on the 14th, elements of Company A, 127th Infantry, began moving into the forward perimeter to reinforce Captain Fulmer's beleaguered units. The 1st Platoon of Company C and the 81-mm. mortar section also moved forward in preparation for continuing the advance.
General Martin took charge of the East Sector on the same day, relocating all troops except the Nyaparake Force to the west bank of the Driniumor River. The East Sector forces were supplied by a variety of methods. Units along the coast were supported directly by small boat from BLUE Beach or by native ration trains moving along the coastal track. Supplies to the Afua area went south from the coast along the Anamo-Afua trail or, later, over the inland track from the Tadji fields through Chinapelli and Palauru. Wheeled transport was impracticable except along short stretches of the coastal track. In early June, when the Japanese ambushed many ration parties which attempted to reach Afua, experiments were made with air supply from the Tadji strips. Breakage and loss were heavy at first, but air supply rapidly became more successful as pilots gained experience and ground troops located good dropping grounds. A dropping ground cleared on the west bank of the Driniumor about 2200 yards north of Afua soon became the principal source of supply for troops in the Afua area. Communications during operations east of the Driniumor were carried out principally by radio, but between units along the river and from the stream back to higher headquarters telephone became the principal means of communication. Keeping the telephone lines in service was a task to which much time and effort had to be devoted. The Japanese continually cut the lines, or American troops and heavy equipment accidentally broke the wires. The enemy often stationed riflemen to cover breaks in the line, thus making repair work dangerous. Usually, it was found less time consuming and less hazardous to string new wire than to attempt to find and repair breaks. As a result, miles of telephone wire soon lined the ground along the trails or was strung along the trees in the Driniumor River area and back to the Tadji perimeter. Despite this adjustment, Nakai escalated pressure, advancing beyond Yakamul by month's end. In response, Gill replaced the Nyaparake Force with the 1st Battalion, 126th Regiment, which swiftly recaptured Yakamul and Parakovio. Despite initial success, Nakai's forces launched a heavy counterattack in early June, reclaiming Yakamul by June 5.
In the meantime, additional Japanese units had been conducting exploratory missions inland against Afua since the beginning of the month. However, Howe’s 1st Battalion ultimately succeeded in repelling them. This allowed Martin’s forces to establish an outer defensive line along the Driniumor River. From there, they continued forward patrols toward the Japanese lines. While the 41st and 51st Divisions struggled to move personnel and supplies to the forward assembly area, Nakai efficiently organized a counter-reconnaissance screen along Niumen Creek to prevent East Sector troops from gathering intelligence about deployments farther east. On June 20, due to the increasingly dire situation in Western New Guinea, the 18th Army was suddenly transferred from 2nd Area Army control to the direct command of the Southern Army. Although General Terauchi's directive was to execute a "delaying action at strategic positions," General Adachi opted to adhere to his original plans for a westward offensive. He was determined to maximize the effectiveness of his forces while they still possessed fighting capability, aiming to divert as much enemy strength as possible away from the Western New Guinea battlefront. Sensing an imminent heavy enemy assault, Generals Krueger and MacArthur decided to reinforce Aitape with General Cunningham’s 112th Cavalry Regiment, arriving on June 27, and Colonel Edward “Ted” Starr’s 124th Regiment, expected to arrive in early July. They also expedited the shipment of the 43rd Division from its New Zealand staging area to Aitape, necessitating the establishment of Major-General Charles Hall’s 11th Corps. Upon assuming command of the task force on June 29, Hall reorganized his forces and implemented several troop redeployments in preparation for the looming enemy attack.
By June 30th, Adachi had completed concentrating his forces in the assembly area. Consequently, he swiftly initiated preparations for launching an attack against the Driniumor River line on July 10th. His strategy involved Colonel Nara Masahiko’s 237th Regiment crossing the river and launching an assault westward towards Koronal Creek, and northwest to clear Anamo and other Paup villages. Meanwhile, the 78th and 80th Regiments were tasked with clearing the Afua area and advancing all the way to Chinapelli. Success in this endeavor would pave the way for Japanese units to advance towards the Tadji airstrips. Furthermore, a Coastal Attack Force was designated to carry out a diversionary maneuver along the coast, aiming to engage the enemy and constrain them with artillery fire.
In early July, as the Japanese finalized their preparations, Hall and Martin made the decision to dispatch robust patrols east of the Driniumor to the Harech River. However, these patrols were only able to advance as far as Yakamul, where they encountered only the enemy’s forward units. Consequently, on July 10th, Hall and Martin ordered the 1st Battalion, 128th Regiment, and the 2nd Squadron, 112th Cavalry to conduct a reconnaissance mission across the Driniumor. Subsequently, the infantry faced significant resistance as they pushed towards Yakamul, while the cavalry's progress was limited to about a mile due to the dense jungle terrain. Despite these efforts yielding disappointing results, a captured Japanese soldier disclosed that their attack was imminent that night. However, this critical piece of information was mistakenly disregarded by the American command, leaving Adachi and Nakai poised to launch their counteroffensive.
Around midnight, the assault commenced with the 1st Battalion, 78th Regiment charging across the Driniumor River, facing Company G of the 128th Regiment along a narrow front.
The Japanese attacked in two or three screaming waves, broadening the front after the first assault by throwing in the rest of the 78th Infantry and possibly elements of the 80th Infantry. Japanese reconnaissance had been good--the attackers knew the locations of company and battalion command posts all along the American defenses but not quite good enough. The enemy did not know that Company G had been reinforced during the afternoon of 10 July nor, apparently, had he discovered that the company's front was protected by low barbed wire. The attacks of the 78th Infantry were thrown back with heavy losses. Machine gun and mortar fire from the 2d Battalion, 128th Infantry, accounted for many Japanese, numbers of whom were caught as they tried to cross the barbed wire in front of Company G. According to Japanese sources, the results of American artillery fire were even more disastrous. As soon as the enemy attack had begun, the 120th and 129th Field Artillery Battalions had started firing previously prepared concentrations along the bed and east bank of the Driniumor. The Japanese units in or near the impact areas suffered heavy casualties. The 1st Battalion. 78th Infantry, was quickly reduced from 400 to 30 men, principally as a result of the American artillery fire, which also destroyed large numbers of artillery weapons, machine guns, and mortars.
Despite this, the Americans, skillfully backed by artillery support, ultimately repelled them with significant casualties. Following this initial repulse, Martin concluded that a reconnaissance in force was unnecessary and ordered the units involved to retreat behind the Driniumor River. Confusion among many Japanese units, arriving late, had delayed the commencement of the 80th Regiment's attack, which was directed at Company E and was similarly pushed back. But a second wave of attackers, probably comprising the 237th Infantry and heretofore uncommitted elements of the Right Flank Unit, began pouring across the Driniumor toward Company E at approximately 0200. The new attackers overran the company command post and surrounded most of the unit's widely separated strong points. Fighting continued in the company sector for a little while, but the unit could not long withstand the overwhelming enemy pressure. Company organization and communications broke down. Worse still, the troops began to run out of ammunition. A general withdrawal commenced.
By 03:00, the Japanese had breached a gap approximately 1300 yards wide in the American lines, physically occupying that territory. Fortunately, the following hours remained relatively calm as the 78th and 80th Regiments regrouped to the south to resume the offensive. This lull enabled Martin to dispatch the 1st Battalion, 128th Regiment to counterattack along the Anamo-Afua trail, aiming to reinforce the 2nd Battalion's positions. Initially encountering no resistance for the first 1500 yards, the Americans were eventually halted by intense enemy fire at 10:30, compelling them to retreat back to Tiver. This fierce opposition convinced Martin that the enemy could advance directly westward with minimal hindrance towards the Tadji strips unless he abandoned the Driniumor River line. He decided to reorganize his forces along the secondary delaying position at the X-ray River-Koronal Creek line, preparing for further counterattacks against the Japanese.
Accordingly, while Company F maintained their position along the coast, the 128th Regiment began to fall back towards the creek. Further south, Cunningham opted to withdraw his cavalrymen in two stages, successfully reaching X-ray by midnight. However, communication issues delayed Howe’s 3rd Battalion, with most of the unit arriving at the river the following day. A small contingent had to engage in combat with Japanese forces and couldn't reach X-ray until July 13. Despite this, Krueger and Hall disagreed with the decision to abandon the Driniumor, promptly deploying the 124th Regiment for a potential counterattack. Martin, who was instructed to hold his position, was replaced by Gill, assuming direct command of the divided covering force, now split into North and South Forces. However, before the American counterattack could commence, Nara’s infantry launched an assault towards Tiver and Koronal Creek on July 12. The 128th Regiment successfully repelled them after a fierce confrontation. Meanwhile, Adachi dispatched the main body of the 41st Division and the reserve 66th Regiment towards the Driniumor, augmenting pressure on the Paup coast. To the south, Nakai’s units gathered across the river near Afua and Kwamrgnirk, preparing for a final northward push. Finally, at 07:30 on July 13, the American counteroffensive commenced as the 1st Battalion, 128th Regiment swiftly moved from Tiver to Chakila, only to be ambushed by Japanese artillery. Nevertheless, precise artillery counterfire silenced most of the enemy artillery, enabling the Americans to advance eastward toward the mouth of the Driniumor.
Meanwhile, the 124th Regiment under Starr's command advanced southward along the Anamo-Afua trail, facing strong opposition from the 237th Regiment. Despite encountering resistance, they managed to reach the river, although still positioned considerably north of their designated centerline. Cunningham's South Force began its eastward movement from the X-ray River at 10:00, successfully overcoming enemy positions along several stream crossings to reach the Driniumor near Afua. Consequently, all original crossing points on the Driniumor fell to the Allied forces, isolating the 20th Division and the 237th Regiment several miles west of the river's bank. By nightfall, Nara had regrouped his 237th Regiment for another assault on the 2nd Battalion, 128th Regiment. Company E demonstrated its combat effectiveness by holding firm and repelling the Japanese forces, with the rest of the battalion successfully defending against subsequent small-scale attacks, marking the conclusion of Nara’s offensive actions. The following morning, Gill’s forces consolidated their defensive positions along the reformed river line, albeit with a 1500-yard gap remaining in the center. Yet this all for today with Noemfoor as we now need to head over to the India-Burma theater.
The final phase was coming for the Battle of Imphal. By the start of July, the reopening of the Imphal–Kohima Road facilitated the resupply of the 4th Corps, enabling them to launch an offensive against the fatigued and under-resourced troops under General Mutaguchi's command. Additionally, three brigades from General Stopford’s 33rd Corps advanced from the north, swiftly joining General Gracey’s 20th Division in an endeavor to reopen the Ukhrul Road.
Under intense pressure, General Yamauchi’s battered 15th Division units hastily abandoned Tongou and Sokpao, leading to the 80th Brigade occupying Lamu by July 2. The next day, the ailing general, who had long fallen out of favor with Mutaguchi, was carried from the battlefield on a stretcher and later died in a hospital at Maymyo. Lieutenant-General Shibata Uichi replaced him and promptly prepared the 51st and 67th Regiments to retreat. To cover their withdrawal, the newly arrived and utterly exhausted 60th Regiment was tasked with attacking towards Lamu, while General Miyazaki’s troops assembled behind Ukhrul. However, the 60th Regiment was so weakened that its attacks were easily repelled, and the 67th Regiment retreated in disorder, leaving the 51st encircled. On July 8, Colonel Omoto’s troops fiercely broke through the encirclement in three columns, allowing Stopford’s brigades to finally overcome Japanese resistance at Ukhrul and capture the town. This forced Shibata to regroup his forces along a new line from Lungshong through Sangshak to Sakok, ultimately enabling the British-Indian forces to reopen the Ukhrul Road by July 10. With both supply roads reopened, the arrival of Stopford’s brigades from the north, and the Japanese forces nearly routed, General Slim decided it was time to go on the offensive. Slim's plan involved the 33rd Corps taking over the Shenam Saddle and the Tamu–Palel Road while the 4th Corps cleared the Japanese from the Silchar Track and the Tiddim Road.
On the other hand, Mutaguchi was still planning a combined attack on the Palel area involving the 15th Division, remnants of the 31st Division, and some units from the 33rd Division. Although he issued an attack order, the divisions were too battered to comply. The overall situation of the 15th Army went from bad to worse and the only hope remaining was to rally the 31st at Humine, give the troops a few days rest and then, after a reorganization, to dispatch them to the northern flank of the Yamamoto Detachment to capture Palel. In early July the 31st Division was concentrated in the area east of Myothit but discipline had disintegrated to the point that the Division could scarcely be termed a combat force. The Torikai Unit was organized with the 138th Infantry Regiment (less one battalion); the 2d Battalion, 124th Infantry Regiment and one artillery battalion to reinforce the Yamamoto Detachment. At the same time,the 15th Army ordered the 33rd Division to attack Palel from the south with the 214th Infantry Regiment. The newly formed Torikai' Unit, however, failed to join the Yamamoto Detachment and the order for the 33rd to attack Palel was never carried out.
Consequently, on July 9, General Kawabe had no choice but to order preparations for a withdrawal to a line connecting the Zibyu Mountains, Mawlaik, Kalewa, and Gangaw. Mutaguchi intended to begin the retreat on July 16, directing the 15th Division towards Sittaung, the 31st Division to Thaungdut, and the 33rd Division to Tiddim, while the Yamamoto Detachment would hold the Shenam Saddle until July 24 and then retreat to the Kuntaung-Moreh line to cover the main Army's withdrawal from the Kabaw Valley.
On the southwest front, General Tanaka’s forces had already started retreating from the Bishenpur area, leaving a small covering force at Ningthoukhong to prevent a pursuit by the 17th Division. As a result, General Cowan’s brigades made limited progress against the stubborn rearguard, ultimately securing Ningthoukhong on July 16 after heavy bombardment, coinciding with Mutaguchi’s general withdrawal. By the middle of July, Japanese resistance centered on Ningthoukhong Kha Khunou. A small hamlet about 300 meters wide and 500 meters long, it lay to the immediate south of Ningthoukhong. Despite probing attacks by the 48th Indian Brigade’s infantry and artillery firing on their defenses, the Japanese held on. Finally, in the early hours of 16 July, this small space was subjected to what some describe as one of the heaviest artillery concentrations yet in the Burma Campaign; in the space of an hour, approximately 9,000 shells were fired on Ningthoukhong Kha Khunou. Fortunately for the Japanese, they had withdrawn from the village just before the shelling began. By the time it ended, the village had been completely flattened and was pockmarked with waterlogged craters. And so the last Japanese stronghold in the Imphal Valley was taken. The 63rd Indian Brigade also reached and occupied the Laimanai area around the same time. The 5th Indian Division, the other division in the reconstituted IV Corps, now took over and commenced the chase of the Japanese 33rd Division down the road towards Tiddim.
The 5th Division, now led by Major-General Geoffrey Evans, continued the pursuit while Stopford’s brigades harassed the disordered retreat of the 15th and 31st Divisions. Despite their efforts, the 15th and 31st Divisions reached Thaungdut by early August, and the 33rd Division managed to assemble around Chikha by mid-August, under significant pressure and the serious threat of having their withdrawal route cut off. The 33rd Division distinguished itself by displaying almost superhuman fighting power and repeatedly launched counterattacks against the pursuing British-Indian 5th Division. The Yamamoto Detachment, however, had failed to cover the Yazagyo area and, in mid-August the 33rd Division found itself the vicinity of Chikha facing the serious threat of having its route of withdrawal cut by the enemy which was infiltrating into the Yazagyo area from Moreh and Shuganu through the Kabaw Valley.
On the south-eastern approach to Imphal, the two armies continued to face each other on the Shenam Saddle. Yamamoto Force remained in place on these heights and the front line was still on Scraggy. It was in the second half of July that a final, concerted effort was made to evict Yamamoto Force and push it down the Tamu–Palel Road towards the India–Burma frontier. Led by the 23rd Indian Division , the operation involved five brigades in a three-pronged attack. The central thrust was by the 37th Indian Brigade on the Shenam Saddle, with the support of all available artillery and tanks; the 5th British Brigade was deployed behind it and readied to provide assistance. D-day was to be 24 July. The 1st Indian Brigade was sent through the hills on the right, to arrive behind the saddle. The two were to push the Japanese back on the road. It was hoped their withdrawal route would be cut by the 49th Indian Brigade, which would arrive on the road after looping in from the far left; the 268th Indian Brigade would be to its left, protecting its flank.
Before the Japanese could retreat, the 49th Brigade had cut off General Yamamoto’s withdrawal route by looping in from the far left. However, Mutaguchi had sent Colonel Sato Genpachi’s reserve 61st Regiment to Tamu, which quickly counterattacked and reopened the route. Consequently, Yamamoto withdrew to Moreh, allowing Roberts to swiftly capture Nippon Hill and Scraggy. Within two days, the 23rd Division advanced down the road, forcing the Yamamoto Detachment to retreat toward Mawlaik on July 30. This marked the end of the Battle of Imphal and Operation U-Go, the Japanese Army’s largest land defeat. Estimates vary, but about 30,000 Japanese soldiers died and 23,000 were injured during the operation, including 6,000 killed at Kohima and 16,000 at Imphal. Additionally, the INA lost about 2,000 dead and 2,000 wounded. On the other hand, the British-Indians suffered 16,000 casualties, with over 12,000 at Imphal. Though Mutaguchi’s plan was initially effective and nearly succeeded in capturing Imphal, he underestimated the enemy’s ability to resist his troops and quickly bring reinforcements. Slim’s overall strategy for Imphal succeeded, as the Japanese overextended themselves from the Chindwin River to the Imphal Valley, just as he had predicted. A crucial factor in the British-Indian success was the air support, which kept the 14th Army supplied despite the road to Kohima being cut off. Ultimately, in an attempt to thwart a potential British-Indian advance into Burma, Mutaguchi’s 15th Army was utterly decimated by the failed attempt to capture Imphal. This failure allowed Slim to seize the moment and launch a rapid offensive into Burma, countering the Japanese U-Go plan. The Allies thus gained the upper hand, marking the beginning of the end for Japanese control over Burma.
As a final note for this week by late July, Admiral Somerville executed Operation Crimson, a coordinated naval and air assault on Japanese airfields in Sabang, Lhoknga, and Kutaraja. Departing Trincomalee on July 22, Somerville’s Task Force 62, comprising two carriers and four battleships, arrived off Sabang on the morning of July 25, ready to commence the bombardment. On 5th July 1944 the carriers Victorious and Indomitable arrived in Colombo. The former sailed with Illustrious on 22 July for Operation ‘Crimson’, a bombardment of Sabang by the battleships over which the carrier-borne aircraft were to provide cover and take photographs of the damage. Illustrious embarked the same aircraft as before with Victorious for a total of thirty-nine Corsairs; together they comprised 47 Naval Fighter Wing commanded by Lieutenant Commander Turnbull. The force assembled for the operation was designated TF 62 and the carriers were supported by Queen Elizabeth, Valiant, Renown, Richelieu, Nigeria, Kenya, Gambia, Ceylon, Cumberland, Phoebe, Tromp, Relentless, Rotherham, Racehorse, Raider, Roebuck, Rocket, Rapid, Quilliam, Quality and Quickmatch. The submarines Templar and Tantalus were deployed to ASR positions. The carriers operated only thirty-five miles north of Sabang, not far from the battleships, which approached their bombardment positions at 06:40.
The initial launch was planned for thirty-three minutes before sunrise but this proved to be too early as the morning was exceptionally dark and the launch was delayed for five minutes. Even then it was too early and the form-up was clumsy and slow, delaying departure. The fighters were briefed to attack Sabang, Lho Nga and Kotaraja airfields but 1838 NAS made a bad landfall since maps lacked detail and no photographs were available. When the target airfields were found it was still too dark for accurate strafing but the enemy was alert and opened fire as soon as aircraft came within range. To aircrew accustomed to the excellent intelligence material by then available in the Home Fleet, this caused concern and it had to be accepted that it was difficult to obtain good targets without losing the element of surprise. At very low level on a dark morning, flying at 400 knots with flashes from antiaircraft gunfire all around, camouflaged aircraft in revetments were inconspicuous and the strafing runs were not a success. One Corsair was shot down but the pilot was rescued.
Concurrently, the battleships targeted harbor facilities and military barracks at Sabang, while cruisers and destroyers shelled radar and wireless stations and engaged enemy shore batteries. After the main bombardment, the destroyers Tromp, Quality, Quickmatch, and Quilliam entered Sabang harbor, attacking Japanese positions and launching torpedoes, sustaining light damage from return fire. On the return journey, two enemy reconnaissance aircraft were intercepted and shot down by fighters. Additionally, ten Zeros attacked Somerville’s convoy but were intercepted by 13 Corsairs, leading to two Zeros being shot down and another two damageFollowing this engagement, British pilots noted that the Japanese airmen were not as proficient as they had been in 1942.
Although Operation Crimson's outcomes were not spectacular, Somerville’s final offensive was still deemed successful enough. Due to health concerns, he was subsequently transferred to diplomatic duties at Admiral Mountbatten’s request. Currently, Admiral Mountbatten was moving toward a complete rearrangement of the higher officers in SEAC. From the time of his arrival in the Far East, he had had trouble with his three commanders in chief. When the Imphal crisis arose, Mountbatten was dissatisfied with General Giffard's conduct of operations, and when he later found Giffard taking what Mountbatten considered a highly negative approach toward an aggressive conduct of operations he resolved to ask for Giffard's relief. Mountbatten's relations with Admiral Somerville had been equally difficult. Somerville had refused to treat him as a Supreme Commander and in Mountbatten's opinion tried to make him simply the chairman of a commanders-in-chief committee. As for the RAF commander, Air Chief Marshal Peirse, Mountbatten was not seeking his relief because he did not wish to change all of his principal subordinates simultaneously. After his relief, Somerville was placed in charge of the British naval delegation in Washington DC in October 1944 where he managed—to the surprise of almost everyone—to get on very well with the notoriously abrasive and anti-British Admiral Ernest King, the United States' Chief of Naval Operations.

The Battle of Noemfoor was just getting started, seeing General Douglas MacArthur not giving the Japanese a moment to catch their breath. Meanwhile the battle for Imphal was finally coming to a bitter end as Mutaguchi’s megalomaniac operation was clearly a disaster.

- 137 - Pacific War - Fall of Saipan, July 2-9,1944
2 jul· The Pacific War - week by week
Last time we spoke about operation forager and the Changsha-Hengyang campaign. On Saipan, General Holland Smith's forces advanced with the 4th Marine Division targeting Hill 600 and the 2nd Marine Division capturing Mounts Tipo Pale and Tapotchau. The 27th Division supported these efforts, encountering resistance and challenging terrain. Meanwhile, the 27th Division, under new leadership, made progress despite difficulties. Concurrently, Japanese forces initiated a three-pronged assault in Hunan, capturing significant territory despite supply challenges and heavy rain. On June 11, the 40th Division took control of Yiyang while the 34th Division moved toward Yuelu Mountain. The 68th and 116th bypassed Changsha towards Guanqiao, with the 3rd and 13th facing resistance near Liuyang, which fell on June 14. Xue Yue retreated to Liling as Chinese defenses crumbled. Concurrently, the U.S. initiated Operation Matterhorn, targeting Japan's industrial sites. Despite challenges, the initial bombing runs prompted further strategic bombings, marking a significant phase in the Pacific War.
This episode is the Fall of Saipan

As we last saw, the Americans had begun their advance into Central Saipan. They achieved significant success on the right with the 4th Marine Division, but faced difficulties breaking through on the left and center. Following the victory in the Philippine Sea, Admiral Turner successfully completed unloading operations, landing approximately 60,000 troops and 75,000 tons of supplies by June 26. To maintain air superiority, Admiral Mitscher conducted raids on the islands of Pagan, Tinian, Guam, Rota, and Iwo Jima, and continued these raids over the next few days, despite ongoing Japanese night air attacks against the American beachhead.
In a strategic effort to keep the Japanese unsettled and unable to prepare for counterattacks, Carrier Task Group One raided Pagan Island on June 23rd. The neighboring islands in the Marianas were also not ignored; almost daily photo reconnaissance missions were conducted over Guam and Tinian to monitor any changes in their situation or positions before the landings. On June 25, Carrier Task Group Three carried out intense bombing raids on Guam and Rota to further incapacitate the airfields and installations there.
The first significant naval raid following the battle, beyond routine operations, was an attempted strike against the Volcano-Bonin group, which escalated into a substantial air battle initiated by the Japanese. At 6:00 on June 24th, Vice Admiral Joseph J. Clark's Task Group 58.1, comprising the Hornet, Yorktown, and Bataan launched a long-range fighter sweep of 48 Hellcats against Iwo Jima, which was intercepted by numerous enemy fighters. In the ensuing battle, four U.S. Hellcats were lost, while Japanese losses were estimated at 68 fighters and bombers. Despite this defeat, the Japanese attempted another attack against Clark's task group with the remnants of their local air force. This attempt ended disastrously for them, as U.S. interceptors shot down an additional 46 aircraft, bringing the day's total to 114. Task Group 58.1, having completed its mission without bombing the airfields, safely returned to Eniwetok without incident.
On the opposing side, after the fall of Mount Tapotchau, General Saito organized a final line of resistance between Tanapag, Radar Hill, and Tarahoho. In a brief resume on the morning of 27th June, Major General Igeta summarized the situation: “The summit of Tapotchau was occupied yesterday evening. Front line units tried to retake it with a night attack, but did not succeed as planned. In Donnay the enemy broke through with a number of tanks, but their advance was slow. Thereafter, no great change in the situation. The defense force, along with the firmest possible defense of its present front line and its activities toward annihilation of the enemy, is at present setting up with a line between Tanapag--Hill 221 (Radar Hill)--Tarahoho as the final line of resistance… Meanwhile, about 50 men of the 118th Infantry are improving their positions on the east side of Hill 343, and one company of the 136th Infantry is improving its position on Hill 268, and about 50 men of the 118 Infantry are digging in on the north side of that hill. The main body of the 9th Expeditionary Force, about 200 men, and about 100 men from the 9th Tank Regiment are consolidating their positions north and east of there in the high ground (Chacha water area).”Although the pre-landing preparations had been largely ineffective, continuous naval bombardment during the battle forced his troops to stay low and defend under intense pressure.
For the June 27 attack, General Smith ordered the three divisions to advance side by side and capture the O-6 Line. On General Schmidt’s front, progress was swift. The 23rd Marines advanced quickly, facing only sporadic rifle fire from the villages of Donnay and Hashigoru, and reached their objective. Meanwhile, the 165th Regiment moved rapidly through the hills but struggled to maintain contact, requiring the deployment of a battalion from the 24th Marines to fill the gap and repel an enemy tank attack. In the center, the 106th Regiment encircled Hell’s Pocket and established a cordon at the north end of Death Valley, although they made little progress against Hill Able. To the left, General Watson’s Marines advanced about 200 yards along Mount Tapotchau's western slopes while the division realigned its lines.
Despite largely ineffective pre-landing preparations, the continuous naval bombardment during the battle forced enemy troops to stay under cover and defend under intense pressure. In General Saito’s words “The practical experiences of the defense forces of Saipan… have to do with the power of the enemy naval bombardment. If there just were no naval gunfire, we feel with determination that we could fight it out with the enemy in a decisive battle.” Underwater mines, which the Japanese had used as land mines, were found along the road and railroad in the vicinity of Donnay. Tanks detoured these mined areas without difficulty, however. A Japanese supply dump, found near Hashigoru, contained new clothing, ammunition, and infantry weapons. Lieutenant Colonel Dillon's 2nd Battalion, moving through the matted vegetation and ragged cliff line along the coast, experienced difficulty keeping abreast of the faster-moving 3d Battalion. Since a detailed search of the gnarled coast line could not be instituted without sacrificing the momentum of the attack, Colonel Jones ordered the 1st Battalion to follow Dillon's unit at 400 yards, mopping up and investigating suspicious areas. By 4:40pm the 23rd Marines had trudged to objective O-6. Both battalions immediately dispatched security-reconnaissance patrols to their front but made no contacts with the enemy.
The next day, Major-General George Griner arrived to assume command of the 27th Division, immediately reorganizing his units and deploying the reserve 3rd Battalion, 105th Regiment. The 3rd Battalion, 106th Regiment had suffered heavy casualties in its Death Valley fight. By June 28 its effective strength of riflemen numbered approximately 100, and it was reorganized into a single rifle company. Among the 3rd Battalion's casualties on June 28 was the commanding officer, Lieutenant Colonel Harold I. Mizony, USA, killed in action when two Japanese tanks unexpectedly appeared just forward of his battalion observation post. By chance, the two enemy vehicles had found a lucrative target; commanders of the 2nd and 3rd Battalions, together with their company commanders, were gathered to plan the next move. Tightly grouped a short distance behind them were the men of the two battalions, waiting for the orders that would send them into action. Within a matter of moments the enemy tankers reaped an awful harvest, including 12 killed and 61 wounded, and then disappeared unscathed.
On General Watson’s front, Major Hunt's 2nd Battalion continued to fight across the open canefield toward its objective, a low ridge line north of Tipo Pale. Japanese riflemen and machine gunners, secure in their hillside grotto, raked the clearing with grazing fire. Light flame-thrower and medium tanks were available to the 6th Marines, but their use in this instance was limited because of difficult routes of approach to enemy positions, and support had to be delivered from long ranges. This left the task to the infantrymen. As everywhere demonstrated, reduction of cave positions proved a slow, painful job. By late afternoon the situation had improved slightly and the volume of Japanese fire had diminished somewhat, but the 2nd Battalion's unceasing efforts since 6:30 found it still short of the ridge line objective and very tired. A great store of energy had been burned in moving across the murderous field, yet more effort would be required. It appeared that the Japanese were rooted to the pock-marked ridge line. The Tipo Pale strong point, at which Company K, 6th Marines, had been whittling for many days, finally was secured on 28 June, permitting the company to rejoin its battalion. The tenacious Japanese soldiers in this pocket had sold their lives but had exacted from the 6th Marines a high price in time, men and effort.
The 8th Marines encountered tough Japanese resistance and difficult terrain while advancing against four small hills known as the Pimples, achieving minimal progress. Meanwhile, Schmidt, positioned well behind the 27th Division, received orders to maintain current positions. However, the 23rd Regiment conducted patrols beyond its lines up to 500 yards, and the 165th Regiment secured Hill 700 to complete the movement to the O-6 Line. Over the following two days, combat fatigue and the need for the 27th Division to catch up slowed the Marine divisions almost to a halt. Beginning their attack at 11:00 on June 29, the 3rd Battalion, 105th Regiment successfully closed the gap on Griner’s right flank by about 800 yards, eventually linking up with the 24th Marines the next day. On the left, the 106th Regiment encountered heavy resistance but eventually captured Death Valley and Hell’s Pocket, establishing contact with the 8th Marines by June 30. Behind them, the 2nd Battalion, 165th Regiment secured Hill Able and the remaining portion of Purple Heart Ridge. Meanwhile, the Marines and the 165th Regiment conducted patrols, cleared out remaining enemy forces, and fortified their positions. The 6th and 8th Marines also made some limited progress northward, culminating in the capture of Bill’s Pimple.
During the night of June 30, the Japanese commenced their withdrawal towards Saito’s final defensive line in an organized manner despite facing artillery fire. This new defensive line, though shorter, provided an opportunity for Saito to regroup his troops and strengthen their defense. However, failure to hold this position would spell disaster for him and his soldiers. Upon learning of the Japanese retreat, the American forces resumed their offensive on July 1, encountering stubborn resistance from remaining Japanese pockets that needed to be cleared out. The following day, General Smith's forces launched a coordinated attack. On the left flank, Colonel Stuart’s 2nd Marines swiftly advanced through Garapan, Flametree, and Sugarloaf Hills, while the 6th Marines made significant gains after neutralizing an enemy stronghold. The 8th Marines, after securing the Pimples, faced heavy Japanese resistance at Limestone Hill. In the meantime, evacuation of casualties had become a problem: Marines had fallen on the open field, and all attempts to rescue them only resulted in more men being hit. The scheme finally adopted, and the one which brought success, was for a tank to position itself between the casualty and the limestone hill. By following directly behind the tanks, hospital corpsmen could then move safely to the wounded, apply hasty bandages, give them a shot of morphine, and place them on stretchers. Then, carefully coordinating their moves with the tank by talking to the driver through the sound-powered phone on the rear sponson, the stretcher bearers would precede the tank from the site, all the while shielded from Japanese fire. White phosphorous rounds dropped on the hill by the 81mm mortar platoon plus frontal blasts from the chaperoning medium tanks also contributed to the success of this resourceful project. The fact that only small arms fire spattered against the thick hulls of the tanks indicated that the Japanese had no heavier weapons readily available in the limestone hill. By dark, all wounded had been rescued, but the task of seizing the hill still remained.
Only a clever night tank raid, utilizing illuminating shells and flamethrower tanks, could eliminate this stubborn Japanese position. In the center, the 106th Regiment advanced despite sporadic fire, while the 105th Regiment had to overcome the Papako strongpoint to make modest gains. With the arrival of the 27th Division at the O-6 Line, the right units could resume their advance. Consequently, the 165th Regiment encountered minimal opposition, advancing 1700 yards, while the 23rd and 24th Marines made virtually unopposed progress to the intermediate O-6A Line.
On June 3, the general offensive persisted, now targeting the O-7 Line. On the front under Watson's command, the 2nd Marines successfully took control of the remaining portions of Garapan, though they encountered difficulty clearing Mutcho Point on the town's northwestern edge. Duty in the town had little to commend it; battered skeletons of what had once been buildings, and humans, and animals, dotted the area; the choking smell of death hung about like a fog. And everywhere were the pieces of corrugated iron which the Japanese and natives had used as roofing for almost every structure from the hen house to the bank. To step on one of these huge rattling sheets was to inform everyone thereabouts of one's presence. Garapan's trash and garbage dump appearance was further enhanced by odd clothing, shoes, papers, books, and miscellaneous bric-a-brac strewn through the area. Perhaps the only bright point was the copious wells, providing adequate water for the 2nd Marines to bathe away some of the filth on their bodies.
The 6th Marines also advanced, halting 1000 yards from the coast, while the 8th Marines faced minimal resistance and gained approximately 1000 yards. Meanwhile, Schmidt's three regiments advanced side by side and in formation, making swift progress over challenging terrain but were ultimately halted before Hill 721 and 4th of July Hill. Nonetheless, the 24th Marines managed to capture Radar Hill, situated at the center of Saito’s final defensive line.
In the central area, Japanese delaying units hindered the 27th Division's progress towards the coast, with the 106th advancing another 1000 yards and the 165th about 500 yards. During the night of July 3rd the 165th Infantry command post became the scene of violent activity when 27 Japanese advanced into the installation, apparently by mistake. All of the Japanese intruders were killed with no loss to personnel of the 165th. In the morning, when an identification could be made, Colonel Ogawa Yukimatsu, commander of the Japanese 136th Infantry, was discovered among the dead. Piecing the story together, it appears that Ogawa and his headquarters group had been by-passed by U. S. advance and that he was attempting to displace to the northeast when he blundered into the 165th's command post. Detailed instructions pertaining to the establishment of Saito’s final line of defense were found on his body, providing the Americans with valuable intelligence for future operations.
The next morning, Griner’s forces continued their northward advance, successfully securing Flores Point and the surrounding high ground. To the right, despite a disappointing artillery barrage, Schmidt's Marines swiftly captured Hill 721 and 4th of July Hill, with a bold patrol securing Hill 767 to the northeast. On the left flank, while the 2nd Marines cleared Mutcho Point and Tanapag Harbor, the 6th and 8th Marines rapidly pushed to the coast, reaching the O-7 Line.
Watson's involvement in the offensive came to an end, with subsequent shifts in the axis of attack by the 27th Division and the 4th Marine Division towards the northeast.
Mindful of the significance of the day in American history and pleased with progress at Saipan, General Holland Smith distributed the following message to the landing force on the evening of July 4th: “The Commanding General takes pride on this INDEPENDENCE DAY in sending his best wishes to the fighting men on Saipan. Your unflagging gallantry and devotion to duty have been worthy of the highest praise of our country. It is fitting that on this 4th of July you should be extremely proud of your achievements. Your fight is no less important than that waged by our forefathers who gave us the liberty and freedom we have long enjoyed. Your deeds to maintain these principles will not be forgotten. To all hands a sincere well done. My confidence in your ability is unbounded.” The entire northern part of the island remained to be seized, including the important Marpi Point area; and this demanded a swing of the axis of attack to the northeast. Holland Smith, therefore, split the unconquered portion in half, assigning the left segment to the 27th Division and the right to the 4th Division. To allow sufficient time for the juggling of frontages and zones, the attack hour was delayed until noon of 5 July. Generals Griner and Schmidt, of the 27th and 4th Divisions respectively, were to "conduct such adjustment of their lines or make minor attacks prior to King-hour as they [deemed] necessary to launch a coordinated attack. . . ." The 4th Division's thrust had pushed well into the newly-assigned zone of the 27th Division, so that the previously described reliefs and shifts were necessary.
The Japanese forces remaining in the upper end of the island were poorly equipped, supplied, and often in poor health, yet they maintained high morale and a readiness to fight to the end. In the final push northward, Griner assumed control of the western front on June 25th. However, the advancement of his 105th and 165th Regiments was hindered by difficult terrain and strong resistance from fortified positions around Harakiri Gulch. On the right flank, the 24th and 25th Marines made successful progress to the O-8A Line after the 23rd Marines secured the intermediate O-7Z Line. Despite concerns of a potential Japanese counterattack during the night, accurate artillery fire dispersed enemy concentrations. The following day, Griner aimed to reach Makunsha by midday, but faced slow progress against obstacles like Harakiri Gulch and along the coastline. Consequently, Smith decided to adjust division boundaries, allowing Schmidt’s Marines to expand northwestward, envelop the 27th Division north of Makunsha, and assume responsibility for the entire front for the sweep to Marpi Point. Under this revised plan, the 27th Division resumed its assault in the afternoon, breaking through a coastal ditch but encountering resistance at the Gulch. Meanwhile, the 23rd Marines, on Schmidt's front, pushed northwest and northeast, with limited progress towards Makunsha. The 24th Marines gained approximately 1800 yards, and the 25th Marines secured Mount Petosukara, where 800 civilians surrendered.
Overnight, attempts to counterattack against Petosukara were swiftly thwarted, but significant action unfolded in the Makunsha region. For the 3rd Battalion, 24th Marines, stationed to protect the regiment's exposed left flank, the action was particularly vicious. Just before dawn the enemy rushed forward, armed with grenades and "idiot sticks," encouraging themselves with loud shouts and screams. Though this thrust failed to penetrate the Marines' lines, some of the enemy fell within five yards of the foremost foxholes. The action report of the 3d Battalion, 24th Marines, estimated the number of enemy killed in this attack at "more than 200."
On July 6, facing the complete breach of his last line of defense and with no options left, Saito realized the futility of the situation. With his forces depleted of essential supplies and under relentless artillery barrage, he issued orders for the remaining troops to execute gyokusai, a final suicidal assault aimed at inflicting maximum damage on the enemy. Several days prior to Saito's final order the assembly of remaining Japanese forces had begun. Some Japanese were out of reach behind U. S. lines, others were hidden in the deep shadows of caves, but all available were mustered. Marpi Point, Paradise Valley and Harakiri Gulch were sites for mobilization and reorganization. Many provisional units were formed in an effort to achieve some degree of tactical unity among the assorted groups and individuals. Weapons and equipment were wanting and some Japanese were armed only with grenades or crudely-fashioned spears. One Japanese staff officer, Major Kiyoshi Yoshida who participated in the battle estimated the total participants at 1,500, many with no weapons. In the light of subsequent events, however, his estimate appears too low. Assuming that he was misinformed on this point, it is not at all surprising; even at the assembly points, U. S. artillery and mortar fire hampered Japanese efforts to organize their troops and an accurate count was impossible. As the conglomerate force moved toward Makunsha, which would serve as a point of departure, it was subjected to persistent, heavy concentrations of artillery fire. This resulted in a limping approach with leaders calling upon every conceivable device to maintain the unity of their commands. Greater silence by the sprawling force would have helped; early in the evening patrols from the 27th Division Reconnaissance Troop had detected unusual activity. This had resulted in the large number of unobserved fire concentrations thrown into the Makunsha vicinity. By nightfall, Generals Saito and Igeta, along with Admiral Nagumo, performed seppuku after a final meal, while Colonel Suzuki Takuji gathered 3000 Japanese fighters, including naval and support personnel, unarmed civilians, and the injured, for a final desperate charge.
The blow fell at 4:45am. First and hardest struck were the isolated positions held by the 1st and 2nd Battalions, 105th Infantry. The attack on these units hit from front, flank and, after moving through the gap, the rear. Almost as soon as the attack was launched, communications to the rear were cut. It was then simply a matter of two isolated battalions of soldiers fighting for their lives. This they did and did well. Some of the soldiers stacked so many dead Japanese forward of their positions that it was necessary to move to get fields of fire. Major McCarthy, commanding the 2d Battalion, described the onslaught: “It reminded me of one of those old cattle stampede scenes of the movies. The camera is in a hole in the ground and you see the herd coming and then they leap up and over you and are gone. Only the Japs just kept coming and coming. I didn't think they'd ever stop.” The sheer weight of this attack, its ponderous momentum, carried it through the soldiers' lines. In addition, hundreds of Japanese moved past the isolated defense area, using the gap on the right. The fanatical surge then carried to the 3rd Battalion, 105th Infantry, located on the high ground overlooking Harakiri Gulch. Here the soldiers were on better defensive terrain; the Japanese had to climb up to them. The lines held, and the Japanese suffered staggering losses. This portion of the battle did not cease with the coming of daylight on 7th July but continued until midafternoon. Next to feel the impetus of the determined thrust was the 3d Battalion, 10th Marines, in firing positions about 500 yards southwest of Tanapag Village. The Japanese mass that struck this unit was apparently that portion of the banzai force which had moved through the gap between the 1st and 3rd Battalions, 105th Infantry. Hardest hit were Batteries H and Headquarters and Service, in position on the left of the railroad track. Batteries I and G, set up on the right of the track also got into the fight, although they were not as closely engaged as the other two. The only battery that actually fired its howitzers during the melee was H, the others being forced to remain silent by the presence of other artillerymen to their front. During the early phases of the battle, before Battery H was forced to abandon its firing positions, one of its howitzers was turned completely around to engage a Japanese medium tank which had ploughed through to the rear. At a range of less than 50 yards the artillerymen sent 105mm shells crashing into, and destroying, their armored target. Eventually, however, the pressure from Japanese infantrymen was too great; Battery H's outnumbered survivors pulled back. In the frantic confusion and haste of the retreat, they failed to remove the breech blocks or firing locks from the howitzers. The Japanese, oddly enough, neither used nor destroyed the weapons while they had control of the area. Battery I had been attacked at 0455, with Japanese advancing astride the railroad track. The first thrust was repulsed and the Japanese fell back to reorganize. A series of actions, followed this same pattern, continued until 0650, when all of the battery's small-arms ammunition was expended. At this time the battery commander, Captain John M. Allen ordered the firing locks removed from the howitzers and the unit to fall back to the positions of Battery G. Here the two batteries continued the fight until relieved by elements of the 106th Infantry later in the day. Located directly behind Battery H, headquarters and service personnel of the battalion were forced to retire after heavy, close-in fighting. Among the 136 casualties in the battalion was the commanding officer, Major William L. Crouch, who was killed. Japanese killed in the encounter numbered 322. Even as the Japanese surged directly against the 3rd Battalion, brother artillerymen of the 4th Battalion, 10th Marines, in position to the southeast, received pressure from the fringe of the main enemy tide. In defense of its firing positions, the battalion killed about 85 Japanese. Despite the turmoil of the banzai attack, the 4th Battalion responded on the morning of 7 July to an urgent request for support originated by the 23d Marines, fighting down the cliffs above Makunsha.
By 05:30, they had advanced further, reaching the command post of the 105th Regiment, where Bishop's hastily assembled American forces, aided by artillery, managed to repel the attack. Concurrently, secondary assaults were launched in Paradise Valley and Harakiri Gulch but were promptly quelled by American firepower. By midday, the banzai charge had been effectively halted, and the few surviving Japanese soldiers retreated to Mamushka, engaging in sporadic skirmishes with American troops throughout the day. Despite a counterattack by the 106th Regiment, they were forced to halt just 200 yards short of the Tanapag perimeter, and by midnight, the remaining American survivors were successfully evacuated.
During this engagement, the 105th incurred 406 fatalities and 512 injuries, while Marine artillery units sustained 45 deaths and 82 injuries. On July 8, at 04:30, the remaining Japanese forces launched another attack on the 106th's positions, only to be swiftly repelled. Against the coastal portion of this line the Japanese executed a vigorous thrust during the night of July 7th. Though the strength, organization and planning of this second attack were weak by comparison with the previous effort, the vigor and determination with which it was executed did not vary. Shortly after midnight a report came from the observation post atop Hill 767; Japanese force moving south. Enemy "feeler" patrols probing for weak spots were engaged as early as 3:00am, but the information that they took back to their commanders must not have been encouraging. No holes existed. The attack, launched about 4:30am, struck the 1st Battalion, 106th Infantry, along the beach. Grazing defensive fires swept across the flat beach like a scythe, cutting all in its path. The Japanese never seriously threatened penetration of the lines and those that attempted to swim around the flank were spotted and killed. Shortly after 7:00am the Japanese attack petered out and died. The 106th Infantry estimated that it had slaughtered about 1,000 of the enemy, while at the same time its own losses were practically negligible.
Watson's Marines then assumed control over most Army units and conducted cleanup operations for the ensuing two days. They discovered a total of 4,311 Japanese casualties, including those inflicted earlier by artillery and naval bombardment. Meanwhile, Schmidt's regiments, supported by the 2nd Marines, faced resistance as they advanced northeast and northwest. The NTLF Operation Order for 8 July instructed the 2d Marine Division, less detachments, to "advance in the present 27th Infantry Division zone of action, pass through elements of [that] division on its front line, attack, mop up and destroy enemy elements. . . . Upon passing through the 27th Infantry Division assume operational control 165th Infantry and 3d Battalion, 6th Marines, . . . assume tactical control within the assigned zone of action at 0630 [8 July]." Upon passage of its lines the 27th Division would revert to NTLF reserve. No effective resistance was offered the 2nd Marine Division after it had passed through the 27th Division on the morning of 8 July, although large numbers of poorly armed and totally disorganized enemy were encountered. Some Japanese used the familiar device of hiding in caves and firing from the deep shadows, but the bulk seemed eager to die and made headlong rushes at the Marines. This foolish expenditure simplified the mop-up. The 6th Marines' action report characterized the day's activities as an "attack . . . against a disorganized, swarming mass of Japs . . . waiting for the final death blow. . . ." Adding the hundreds found strewn through its zone to the number that it disposed of, the 6th Marines made a "conservative estimate" for 8 July of 1,500 dead Japanese in its area. On more rugged terrain inland the 8th Marines encountered much the same type of resistance. Here, with more caves to investigate, the sweep was somewhat slower. One wooded pocket encountered, a deep ravine, caused a minor delay. The tactic that previously had worked so well was again employed: one company stayed behind to contain and mop-up while the rest continued the push. The 8th Marines' zone, being inland of the main path of the banzai attack, contained fewer enemy bodies; but, even so, there was conclusive evidence that a terrific battle had taken place.With this final push, Turner declared the island secured, although General Jarman's garrison troops continued mop-up operations for several months.
Following the declaration that the island was secured, efforts to induce cave-occupants to surrender were intensified. Interpreters, using public address systems, pleaded with people in caves to come out. The device was not only attempted from land but from sea as well. LCI gunboats moved close inshore and broadcast promises of good treatment, for which they were answered with fire from Japanese soldiers in the caves. Even some of Saipan's leading citizens, who had surrendered and received good treatment, talked to those in the caves, urging them to yield. But, for the effort expended, the results were not encouraging. The primary reason for this failure was that the people had been saturated with Japanese propaganda to the effect that the Americans intended to torture and kill them. This had been repeated so often that the people came to believe it. At this time the very zenith of horror occurred. Hundreds of civilians, believing that the end had come, embarked on a ghastly exhibition of self-destruction. Casting their children ahead of them, or embracing them in death, parents flung themselves from the cliffs onto the jagged rocks below. The places they jumped from would become known as "Suicide Cliff" and "Banzai Cliff". Some waded into the surf to drown or employed other gruesome means of destroying themselves. How many civilians died in this orgy of mass hysteria is not known, but it is estimated that around 1000 committed suicide. A commander of a patrol craft (YP) said that the progress of his boat around Marpi Point at this time was slow and tedious because of the hundreds of corpses floating in the water.
On July 13, Colonel Riseley's 3rd Battalion executed the last Marine operation on Saipan, successfully assaulting Maniagassa Island, resulting in 14 Japanese deaths and the capture of 15 others. By the end of the battle, almost the entire Japanese garrison of approximately 28,000 personnel had been eliminated. About 1,700 were taken prisoner, including roughly half who were Korean laborers. Nearly 10,000 Saipan civilians, roughly 40% of the population, perished, with another 14,000 interned. American forces suffered approximately 16,500 casualties, comprising 3,100 fatalities and 13,000 wounded out of a total assault force of 71,000. This casualty rate, exceeding 20%, was comparable to Tarawa and marked the costliest battle for the Americans in the Pacific theater up to that point. That is all for today with Saipan as we now need to head over to New Guinea.
General MacArthur’s next offensive was to be the invasion of Noemfoor Island, codenamed Operation Cyclone. Noemfoor served as a crucial staging ground for Japanese forces destined to reinforce the Biak Detachment, owing mainly to its possession of two vital airfields. Despite being guarded by a modest contingent, primarily consisting of six infantry companies from Colonel Shimizu Suesada’s 219th Regiment, the Japanese presence on the island was scattered, rendering their defense disorganized. Allied estimates of Japanese strength on Noemfoor were too high, for there were not more than 2,000 Japanese on the island. Probably not more than 900 of these could be counted infantry effectives. In addition to the 2,000 Japanese, there were 600-odd Formosan laborers and approximately 500 Javanese slave laborers. The 3d Battalion, 219th Infantry, contained the bulk of the combat troops, but there were also present about 180 men of the 2d Battalion, 219th Infantry, and a like number of the 222d Infantry, 36th Division, troops which had been unable to reach Biak. The Japanese garrison on Noemfoor was commanded by a Colonel Shimizu, who was also the commanding officer of the 219th Infantry. Another unit, commanded by a Major Mori, but apparently under Colonel Shimizu's operational control, seems to have been a provisional organization containing mostly armed service personnel and numbering about 600 men.
General Krueger, anticipating minimal resistance, tasked Colonel Sandlin’s 158th Regiment with Operation Cyclone, overseen by General Patrick. The assault was to be facilitated by Admiral Fechteler’s Task Force 77, supported by cruisers under Admiral Berkey and aircraft from the 5th and 13th Air Forces, which had been conducting preparatory bombings on Noemfoor and enemy air bases in the Vogelkop Peninsula. Patrick's strategy involved landing on Yellow Beach, where the enemy's defenses were perceived to be strongest, aiming for swift American control over Noemfoor's airfields. In many essentials, the landing plans for Noemfoor were very similar to those used at Biak; but in one major essential the Noemfoor landing plan differed radically from that employed at Biak. At the latter island the HURRICANE Task Force had used a beach which, while within easy marching distance of the principal objectives and the main concentration of enemy troops, was relatively undefended. But at Noemfoor, the landing was to be made in the face of the enemy's strongest defenses, known to be located in the Kamiri Drome area. YELLOW Beach, as the landing area was designated, extended approximately 800 yards along the western end of the airfield, which was situated almost at the high water mark. The reef presented fewer hazards there than elsewhere, since it was somewhat narrower than at most other points along the island's coast. The relative narrowness of the reef at Kamiri would also permit LCIs, LCTs, LCMs and LSTs to approach to within 450 yards of the beach, which was believed to be firm at the airfield. Moreover, landing at YELLOW Beach had the advantage of placing the assault troops immediately on their objective, permitting a rapid seizure of Kamiri Drome before the Japanese could recover from the shock of the naval and air bombardments. Enemy forces on the island would be split, and those stationed at Namber and Kornasoren Dromes would be isolated. To minimize casualties during the assault, the landing plan required the most intense naval bombardment witnessed in the Southwest Pacific Area thus far. Additionally, Krueger kept the 503rd Parachute Regiment on standby at Hollandia for airdrop once a suitable landing zone was secured, with the 34th Regiment stationed at Biak in reserve.
With all preparations finalized by the end of June, Fectheler’s unit set off from Toem at 18:00 on June 30, reaching southeastern Biak around 17:40 the following day. Subsequently, the American forces sailed towards Noemfoor, commencing deployment off Yellow Beach by 05:00 on July 2. Prior to the landings, the island had endured significant bombardment from General Kenney’s aircraft the previous day, with additional air assaults conducted leading up to the arrival of the troops. As the soldiers readied for the shoreline assault, Berkey’s cruisers and Fechteler’s destroyers bombarded Yellow Beach and its surroundings for approximately 50 minutes. Immediately before the landing, air bombardment, like much of the naval gunfire, was directed against the low coral ridges and hills behind Kamiri Drome. It was believed that the most determined enemy opposition would come from positions in these ridges, and to neutralize these possible defenses the 33 B-24's, at approximately H minus 15 minutes, dropped 500-pound bombs along the ridge lines.
The intensity of the Allied air and naval bombardment effectively dispersed most of the Japanese forces from the beach or kept those remaining pinned down. With the cessation of bombing, the initial wave of troop-carrying LVT's approached the outer edge of the reef, supported by rocket fire from LCI gunboats. Encountering no resistance, Sandlin’s 1st and 2nd Battalions disembarked near a coral ledge overlooking Kamiri Drome. The American forces then commenced advancement in the west, east, and south directions to expand the beachhead, facing only minor resistance from caves approximately 500 yards from the eastern end of Kamiri Drome. Simultaneously, Sandlin’s 3rd Battalion landed and swiftly joined mop-up operations at the east end of the airstrip, enabling the 2nd Battalion to turn southward towards the Kamiri River without encountering opposition along the way.
By 4:00, the 158th had successfully secured a rectangular area approximately 3000 yards wide and around 800 yards deep, reaching south to the banks of the Kamiri River. Despite enemy mortar fire, unloading operations had progressed well, with over 7100 men, 500 vehicles, and 2250 tons of supplies successfully brought ashore by evening. American casualties for the day were limited to 3 killed, 19 wounded, and 2 injured, while the Japanese suffered 115 dead and 3 captured. In anticipation of potential Japanese resistance elsewhere, Patrick had requested reinforcements, leading Krueger to order Colonel George Jones’ 503rd Parachute Regiment to advance to Kamiri. On July 3 around 05:15, regimental headquarters and the 1st Battalion began loading onto 38 C-47s at Cyclops Drome, with plans for the other two battalions to drop over the following days. Launching was completed by 07:47, with successful arrival over Noemfoor at 10:00. The leading C-47's paratroopers were on the ground just ten minutes later.
The planes were to fly over Kamiri Drome in flights of two each, the first plane at a height of 400 feet and the second echeloned slightly to the right rear at 450 feet. Subsequent flights were to follow at a distance of 300 yards. Contrary to plans, the first two C-47s flew over the strip at a height of about 175 feet, and the next eight planes all flew below 400 feet. Dropping from this low altitude caused the paratroopers in the first ten C-47s to suffer many casualties; more casualties resulted because the planes flew over the strip two abreast. The broad formation caused many paratroopers to land off the southern edge of the 100-foot-wide runway in an area where Allied vehicles, bulldozers, supply dumps, and wrecked Japanese aircraft were located. Additional hazards beyond the cleared area were jagged tree stumps, trees partially destroyed by pre-assault air and naval bombardments, and a number of anti-aircraft gun emplacements. The drop resulted in 72 casualties among the 739 men dropped on July 3, including 31 severe fracture cases, many of whom would not be able to parachute again. Despite these challenges, Jones’s 1st Battalion took control of approximately 2000 yards in the center of the defenses around Kamiri Drome upon arrival, allowing Sandlin’s 2nd and 3rd Battalions to concentrate at the eastern end of the field and expand the perimeter. These battalions then proceeded eastward toward Kornasoren Drome, encountering well-prepared but unmanned defensive positions. Additionally, the 1st Battalion conducted patrols south of the Kamiri River but encountered only a few scattered enemy soldiers. The next day, Jones’ 3rd Battalion initiated their drop on Kamiri Drome. They encountered casualties, with 56 jump injuries among the 685 paratroopers who landed by 10:25. Given the significant injuries from both drops, Krueger and Patrick opted to transport his remaining battalion via water. They would arrive at Noemfoor by July 11. But for now, let's shift focus from Noemfoor to the Wakde-Sarmi area to discuss its final clean-up.
Following the main conflict's conclusion on June 25, General Sibert directed the 3rd Battalion, 1st Regiment and the 3rd Battalion, 63rd Regiment to clear Lone Tree Hill. By June 30, they successfully secured the area. On the same day, the 1st Battalion, 20th Regiment moved through the defile south of the hill and encountered only a few stragglers. Seeking to fully secure the Maffin Bay staging area, Sibert extended the perimeter to the Woske River on July 1 through the 1st Regiment's efforts. By July 4, elements of the 63rd occupied Hill 225, seizing the crest of Mount Saksin the following day. However, Hill 265, located southwest of Hill 225, presented greater challenges due to Japanese resistance and difficult terrain. Yet by July 9, the 1st Battalions of the 1st and 63rd Regiments secured the hill crest, previously held by elements of the 224th Regiment. With the capture of Hill 265, the last enemy stronghold in the Maffin Bay region fell. Meanwhile, General Tagami abandoned the idea of a decisive battle in the Woske sector, opting instead to withdraw the majority of his 36th Division toward Sarmi and Sawar, with remnants of the 224th Regiment assuming defense of Woske.

The fall of Saipan pierced the Japanese inner defensive perimeter, now the home islands were vulnerable to strategic bombing. The battle claimed nearly 50,000 casualties and at least 8000 civilian deaths. The intense percentage of casualties suffered by the Americans would have a profound effect on future American planning for the Pacific War.

- 136 - Pacific War - The Changsha-Hengyang Campaign, June 25 - July 2, 1944
1 jul· The Pacific War - week by week
Last time we spoke about the Great Marianas Turkey Shoot. The battle of the philippine sea saw Admiral Ozawa toss numerous aircraft carrier attacks against US Task Force 58. The numerous strikes proved terribly ineffective, seeing most Japanese aircraft shot down and failing to return to their carriers. Ozawa’s forces faced issues with uncorrected compass deviations and poor communication leading to misidentified targets and unsuccessful attacks. The American pilots managed to intercept and shoot down incredible numbers of Japanese aircraft, dealing Ozawa a terrifying defeat. By the end, they had lost three carriers sunk, two carriers damaged, 395 carrier aircraft, about 200 land-based aircraft, two oilers, and four other damaged ships, with around 3,000 Japanese fatalities. The Americans lost 130 aircraft and 76 aviators, with none of their damaged ships rendered out of service. The Battle of the Philippine Sea, the last carrier-versus-carrier battle of the war, stood out because the most conservative and defensive-minded side emerged victorious.

Today we are first jumping back into the fighting on Saipan, where General Holland Smith’s forces were preparing for the start of the drive into the center of the island. General Holland Smith's strategy involved the 4th Marine Division advancing along the inland road to secure the area southeast of Mount Tapotchau and take Hill 600, which is just north of Magicienne Bay. Meanwhile, the 2nd Marine Division was tasked with capturing Mounts Tipo Pale and Tapotchau, while the 27th Division stood ready to support either Marine division if needed. On the morning of June 22, after a 10-minute artillery barrage, the offensive began.
On General Schmidt’s front, the 24th Marines moved along the shore, facing obstacles in the form of ravines but still reaching the O-4A Line by 13:30. The 25th Marines, advancing in battalions, secured three small ridgelines before being stopped at the fourth, gaining approximately 2000 yards. By noon, as the connection between the two regiments became weak, Schmidt had to send in the reserve 23rd Marines to bridge the gap and push toward Hill 600. Fighting especially troublesome terrain, the 23d Marines made slow progress. Only light enemy resistance from riflemen and machine gunners was encountered, but contact difficulties and time lost trudging up, down, around and through the rugged ground formations, limited the speed of advance. Progress ceased at a point about 200 yards south of objective O-4A, where the unit dug in. To the west, General Watson also made significant advances. The 6th Marines reached the summit of Mount Tipo Pale while the 8th Marines progressed closer to Mount Tapotchau. However, both units encountered obstacles due to enfilading fire from a Japanese stronghold on Tipo Pale, which remained undefeated for two days. Throughout the night, the 27th Division began relieving the worn-out 25th Marines. The 106th Regiment took position against the eastern slopes of Tapotchau, while the 165th faced off against Death Valley. Due to this shift, Holland Smith instructed the 105th Regiment to move north as the division’s reserve, leaving just its 2nd Battalion to clear Nafutan Point. The following morning, the 27th Division's advance was delayed because its regiments struggled to assemble at the line of departure. Meanwhile, Generals Watson and Schmidt had already resumed their offensive, encountering more resistance than the day before.
The 8th Marines initially encountered little resistance as they moved towards Tapotchau, but were stopped when the 106th Regiment had yet to advance. To the left, Colonel Riseley’s 3rd Battalion managed to advance about 400 yards, while the rest of the forces faced the Tipo Pale strongpoint. The 23rd Marines, attacking with battalions in column, Dillon’s 2d Battalion leading, advanced rapidly over rough terrain against machine-gun and rifle fire from Hill 600. Approached from the south. Hill 600 presented an extremely steep slope; and, in the words of the battalion commander, “It was all you could do to climb it, let alone light up it.” The number of Japanese defending the height was not great, but the area was admirably suited for defense and, for about 30 minutes, the fight was close and vicious. Hand grenades passed back and forth as in an overgrown, uncontrolled game of “hot potato.” Despite their struggle against gravity and an obstinate foe, Dillon’s Marines seized the peak and set up a hasty defense against counterattack. From its newly-won position, Dillon’s battalion had an unimpaired view of the whole of Kagman Peninsula. This surge had been executed without benefit of contact with the 27th Division on the left; and, when it was apparent that the latter was still some distance to the rear. General Schmidt ordered the 23d to hold up its advance until Army elements had tied in. Though the peak of the hill was securely in the hands of the 2d Battalion, the battle continued. The hill’s northern slope, cloaked in thick vegetation, was alive with Japanese soldiers. Dillon endeavored to strip them of their concealment by burning the area with flamethrowers, but the efforts were largely unsuccessful. Throughout the remainder of the day and during the night the grenade pitching continued.
In the afternoon, General Ralph Smith’s forces began their assault, with the 106th encountering a strongpoint known as Hell’s Pocket and the 165th being stopped by heavily fortified positions on Purple Heart Ridge. The nature of the terrain facing the 27th Division was to have an unusually vital bearing on the unit’s operations for many days to come. This terrain is well described by the historian attached to the division at Saipan: “The whole mountain [Tapotchau] was stoutly defended by the enemy, but the situation on the two flanks of it was somewhat unusual. On the west side of the peak, the ground sloped sharply to the sea. On the east, Kagman Point side, it dropped in sheer cliffs to a bench or plateau, some six hundred feet below the summit. This plateau, a saddle-shaped piece of land, was some twelve hundred yards across and bordered on the east by a low chain of hills covered with heavy foliage. Beyond them the ground sloped down to Kagman Point on the east or dropped off abruptly to Magicienne Bay on the southeast. The cliffs of Mt. Tapotehau and the chain of hills made a corridor out of the plateau. In the fighting which ensued this corridor was named Death Valley by the men who fought there and the chain of hills came to be known as Purple Heart Ridge.”
At d three divisions of Japanese troops and tanks were massing in front of the 27th Infantry Division. The expected enemy attack materialized at about 6:30, when Japanese tanks struck near the boundary between the 165th and 106th Regiments. The combined efforts of 37mm guns and bazookas in the areas of the 2d Battalion, 165th, and the 3d Battalion, 106th, destroyed five Japanese tanks, but a sixth escaped. This was not enough for the intruders. At about 7:30, in company with infantrymen, five more Japanese tanks struck the right center of the 106th Infantry. The 3d Battalion’s Antitank Platoon and the 1st Platoon of the Regimental Cannon Company accounted for four of the tanks while the fifth, though suffering a hit, broke through the 3d Battalion’s lines. Firing wildly, it sprayed the battalion aid station with machine-gun bullets and set fire to a large ammunition dump nearby. The resultant exploding shells forced the right of the 3d Battalion to withdraw about 100 yards, returning to its original positions after the lire had burned itself out. Holland Smith expressed displeasure over the 27th Division's failure to start its attack on time. He was even more upset when he found out that Colonel Bishop’s 2nd Battalion had not made progress at Nafutan Point. As a result, Major-General Sanderson Jarman had to brief Ralph Smith, who committed to ensuring his regiments advanced on schedule the next day.
On June 24, the 106th and 165th Regiments once again struggled to advance against strong resistance and difficult terrain. An attack toward Nafutan Point in the south also failed, prompting Holland Smith to remove Ralph Smith from command and temporarily appoint Jarman to lead the 27th Division. Colonel Geoffrey O'Connell was assigned to clear Nafutan. In contrast, the 2nd Marines made progress toward Garapan and reached Radio Road on the O-6 Line, where they repelled two strong enemy counterattacks. On the right of the 2nd Marine Division, the 8th Marines continued the fight over nightmarish terrain. As Lieutenant Colonel Hays’ 1sl Battalion moved into the attack, the troublesome pocket, developed on the previous day, came alive again. Matted with undergrowth and trees, the irregular coral limestone formation was favorable for the type of defense the Japanese were employing. Improving the area’s natural assets, they had developed a honeycomb of underground positions. The 1st Battalion, utilizing the most unspectacular of tactics, plodded at its unpleasant task of sealing the caves and killing the occupants. The former chore proved the easier, since in most cases the Japanese had not neglected to plan routes and methods of escape. When the “cavemen" had done as much damage as possible from one position, they would retire to another from which to resume the fight. Shortly after midday, the coordinated efforts of combat engineers armed with flame-throwers, bazookas and demolitions and riflemen showed results; the pocket was eliminated and contact with the 6th Marines again established. By late afternoon the battalion reached the edge of a vast cleared area, desirable from the defense-for-the-night point of view. Since the next satisfactory site was 700 yards farther to the north, the unit halted and dug in. Major Larsen’s 3d Battalion, advancing along the base of a cliff, made good progress, limited only by fairly difficult terrain and the necessity of maintaining contact with flank units. Above the 3d Battalion, along the top of the cliff, moved Lieutenant Colonel Tompkins’ 1st Battalion. 29th Marines. Here the cliff was broken into a rough plateau dotted with smaller plateaus of coral limestone which con tinned rising like irregular stair steps toward Mt Tapotcliau’s crest. The undergrowth in this area was a tangle of fern trees, the roots of which spread out three to eight feet above ground like the ribs of an inverted umbrella, overgrown and interlaced with a strait-jacket of vines. On the battalion’s right flank was a narrow flat ledge covered with grass five feet high and the usual tangle of trees. This ledge, part of the north-south ridge leading to Mt. Tapotchau, was within machine-gun range of the summit. Moving through this intricate snarl was like attempting to swim through a fishermen's net, and Tompkins’ battalion became overextended. At this juncture Colonel Wallace, commanding the 8th Marines, ordered the 2d Battalion to move in behind Tompkins’ right to protect the open flank. As the 8th Marines dug in for the night after an advance of about 700 yards, it again became essential to commit the 37mm Platoon from the Regimental Weapons Company to extend south along the ridge facing the hiatus between the 2nd and 27th Divisions.
Schmidt's division also moved east on Kagman Peninsula, with the 23rd Marines reaching Chacha village and the 24th Marines making rapid coastal gains of around 1200 yards. The next day, while the 2nd Marines held their ground outside Garapan and the 6th Marines tackled the Tipo Pale strongpoint, Colonel Wallace's forces finally attacked Mount Tapotchau. However, the summit was secured by a bold patrol along a ridge line on the right flank, which had to fend off multiple Japanese counterattacks. The 27th Division, under new leadership, resumed its attack, with the 165th taking one-third of Purple Heart Ridge and the 106th making a small entry into Death Valley before withdrawing during the night under enemy pressure. Further south, O'Connell struggled to make headway at Nafutan Point, while on Kagman Peninsula, Schmidt's Marines faced minimal resistance and secured Kagman Hill and the Brown Beaches along the O-6 Line. Additionally, recognizing their desperate situation, Generals Igeta and Saito requested reinforcements from Tinian.
From Sunharon Harbor on the west coast of Tinian, 11 personnel barges carrying a company of the 1st Battalion, 135th Regiment moved out during darkness of 25-26 June bent upon reinforcing Saipan. Spotted by the destroyer Bancroft and the destroyer escort Elden, the barges were fired upon and dispersed. One was reported sunk, while the remainder scurried back to Tinian Town. Later, at about 2:25am, LCI(G)s 438 and 456 observed several barges moving out of Tanapag Harbor on Saipan’s west coast. Immediately opening fire, the LCI(G)s accounted for one sunk and a second damaged; the remainder returned to Tanapag. Both LCI(G)s received some damage during this repulse, however. The 438 received 12 holes in her hull from one of the barges’ 37mm guns, damaging the fire main, starting batteries and radar. The 456 suffered less, with only slight damage to her winch and refrigerator. The 438 suffered one man killed and two wounded and the 456 two wounded. A report from one of the LCIs that the Japanese barges had unleashed torpedoes during this action was later substantiated by a prisoner of war who stated that there were at least three torpedoes fired at U. S. ships at this time.
The Americans responded by initiating a systematic bombardment of Tinian on June 26.Air and naval gunfire alternated daily, working first in one half and then in the other, while artillery fired on any targets escaping other attention. A target map was maintained, information exchanged and new targets posted. Cruisers Birmingham, Montpelier and Indianapolis, using both air and direct shipboard spot, were assigned to execute the naval gunfire portion of the plan, while planes would be provided by Carrier Support Groups One and Two. Meanwhile, Schmidt’s Marines were clearing the Kagman Peninsula, and the 6th Marines bypassed the Tipo Pale strongpoint and secured the ridge linking it to Tapotchau.
In the 8th Marines zone the day’s advances were small. On the left the 1st Battalion regulated its progress on that of the 6th Marines. On the right the 2d Battalion’s advance was restrained because of the lack of contact with 27th Division elements. In the 8th Marines’ center, the 3rd Battalion and the 1st Battalion, 29th Marines, made only small gains. The attached 2nd Battalion, 25th Marines, remained with the regiment during the greater portion of the day, Company E being used in the lines, while the remainder of the battalion was employed in mopping-up operations. As already noted, the 1st Battalion, 8th Marines, could move only as fast as the 6th Marines to its left if it were to retain contact. The cleeply-gashed ground, more than enemy opposition, governed the rate of advance. One unusual enemy tactic employed against the battalion at this time is worthy of note: bundles of picric acid blocks were catapulted upon the Marines by Japanese soldiers located in the craggy rocks along the route. This device showed originality but little else; no casualties were inflicted upon the Marines. Higher on Tapotehau’s western slopes, the 3rd Battalion also fought through difficult terrain. A statement from the 8th Marines’ action report gives an indication of the problems in that zone: “To go from the left flank of 3/8 to the right flank of 3/8 required a two hour and 40 minute march over rough terrain.” At some points the Japanese threw or rolled grenades and demolition charges down upon the Marines as they struggled through the hilly thickets. And as if that were not enough, Japanese positioned above directed plunging machine-gun fire upon the advancing men. The 3d Battalion’s left flank kept pace with the 1st Battalion, but the right flank lagged behind. By nightfall the 3d Battalion’s lines stretched almost north and south along the base of a steep slope. On 25 June the 1st Battalion, 29th Marines, less one company, had secured a foothold on the summit of Mt. Tapotchau. It remained on 26 June, then, for Company B to move up the mountain’s western slope and join the battalion. While waiting for this unit, Lieutenant Colonel Tompkins sent a 25-man combat patrol from Company A to seize the northernmost rise of Tapotehau’s crest. This patrol was repulsed after some hard fighting, and it became apparent that this area would have to be thoroughly battered before a successful effort could be made. In the meantime Company B reached the mountain to,. combing the area on the way. From the 2d Battalion position , the Marines observed men of the 2nd Battalion, 106th Infantry, attempting to move up on the division flank. By the close of the day, however, a gap of 600 yards still existed. To protect the exposed flank, the 2nd Battalion bent its lines to the shape of a horseshoe with one company facing north, one east, and one south. To sum up, the most important developments in the 8th Marines’ sector during the day were the straightening of several small bulges in the lines and consolidation of the dominating heights won on 25 June.
The 106th Regiment, under Colonel Albert Stebbins, failed to launch its attack amid confusion. The 165th Regiment bypassed Death Valley and joined the 4th Marine Division. In the south, after heavy bombardment, O'Connell began making progress against Nafutan Point. Life had not been pleasant for the Japanese defenders on Nafutan Point. From seaward, destroyers pounded the rocks and caves unmercifully; from land, a monotonously heavy volume of fire was maintained by 40mm and 90mm anti-aircraft guns, and 81mm and 60mm mortars, as well as fires of the light tank platoon, the self-propelled mount, and small arms of the 2nd Battalion, 105th Regiment. Movement on the point was rendered very difficult, and the shortage of food and water became acute. As a result, on June 26, Captain Sasaki, commanding the 317th Independent Infantry Battalion of the 47th Independent Mixed Brigade, determined to move his battalion from the Nafutan Point trap and join other Japanese forces which he believed to be in the vicinity of Hill 500. This attack, though better planned than the average Japanese effort, achieved very little, and Sasaki’s password “seven lives for one’s country” remained only a slogan.
However, during the night, the trapped Japanese forces managed to break through O’Connell’s defenses. Moving undiscovered through the thinly spread outposts of the 2d Battalion, 105th Infantry, Sasaki’s force headed for Aslito Airfield. The only indication that men of the 2d Battalion had that the enemy was on the move came at about 0200 when “an extremely large group” stumbled into the command post, about 1,500 yards in rear of the front lines. After a lively skirmish, in which the soldiers suffered 24 casualties, the intruders disappeared. The next morning the bodies of 27 Japanese were found in the immediate command post area. At about 0230 Sasaki’s force struck Aslito Airfield. All U. S. personnel in that area were alerted after the enemy succeeded in setting fire to one P-47 and damaging three others. Seabees and engineers quickly rallied to their unexpected mission, cleared the field of Japanese and set up a hasty defense. At 0430 the Commander, Air Defense Command, reported that enemy .50-caliber machine guns and 20mm guns were firing on Aslito Airfield. After causing confusion at the airfield, the force advanced toward Hill 500, where they expected to find Colonel Oka's 47th Independent Mixed Brigade Headquarters . At about 0520 there were two surprises: the first was to Sasaki’s men, who received an unexpected reception from the 25th Marines on Hill 500, and the second surprise was for the 25th Marines, who were not expecting visitors and, in some cases, found the Japanese in their midst before they realized that anything was afoot. Both participants quickly recovered from the shock, however, and a lively small arms and hand grenade battle ensued. At about the same time, the 14th Marines, in artillery firing positions between Hill 500 and Aslito Airfield, was attacked by another portion of Sasaki’s force. The brunt of this assault was borne by the 2nd Battalion led by Lieutenant Colonel Wilson, which held its fire until a precariously late moment, mistaking the advancing Japanese column for a large U. S. Army patrol scheduled to pass through the area at about this time. A savagely-fought, close-in battle ensued, virtually annihilating the attacking force. Total 14th Marines’ casualties in the skirmish were 33 killed and wounded, while 143 Japanese bodies lay sprawled in the regiment’s immediate area. With the coming of daylight, the 25th Marines were assigned the mission of mopping up the stragglers from the abortive enemy effort of the previous night. Total Japanese losses in the fight around Aslito Airfield, at Hill 500, and in the 14th Marines’ area, plus the 27 June mop-up by the 25th Marines, amounted to approximately 500 dead. The participants, some of whom wore United States uniforms and carried M-1 rifles, appeared greatly in need of water and rations. Yet that is all for Saipan for now, as we will be traveling over to China War.
After the success of Operation Kogo, the Japanese planned for General Yokoyama’s 11th Army to initiate a three-pronged assault in Hunan. The 34th, 58th, 68th, and 116th Divisions would head straight for Changsha, while the 3rd, 13th, and 27th Divisions provided coverage on the eastern flank by advancing towards Liling. Meanwhile, the 40th Division, the 17th Independent Mixed Brigade, and the 5th Independent Brigade secured the Dongting Lake region on the western flank. Additionally, the 70th Division in Jiangxi would launch a diversionary attack towards Hunan. On the night of May 27, following heavy artillery bombardment, Yokoyama initiated his offensive. The 34th, 58th, 68th, and 116th Divisions crossed the Xinqiang River swiftly, while the 3rd, 13th, and 27th Divisions moved south towards Liling. Furthermore, the 216th Regiment launched an amphibious operation towards Yingtianzhen and Xiangyin, catching the Chinese defenders off guard. The following day, the 40th Division and the 109th Regiment began their assault southwards, capturing Anxiang, Nan, Tianxingzhou, and the port of Sanxianhu by May 30. Simultaneously, the 5th and 17th Brigades advanced west towards the Songzizhong River to secure the northern shores of Dongting Lake.
In the east, the Japanese forces encountered minimal resistance and advanced almost 100 kilometers, capturing Tongcheng, Nanjiangzhen, Pingjiang, and Changshouzhen by June 1. In the center, the main Japanese divisions breached the 20th Army’s positions at Guanwang and Changlezhen and reached the Guluo River on June 3. With the enemy seemingly in full retreat, Yokoyama’s forces continued southward, hindered only by a sudden downpour, and reached the Laodao River line by June 6, preparing to besiege Changsha. However, heavy rains delayed these preparations, allowing General Xue Yue time to gather his forces around the city. According to a prearranged plan, the 11th Army used the 27th Division to repair the Chongyang-Tongcheng-Pingjiang-Liuyang road and all engineer regiments under the direct command of the Field Engineer commander to repair the Xinqiang-Xinshizhen-Mianhuapo-Changsha road. Continuous rains, however, greatly delayed the road work and turned the roads into a sea of mud. Lines of communication became extremely difficult to maintain and, until the middle of June, the Japanese first-line troops received very few supplies from the rear. In spite of strenuous efforts on the part of the Army to improve these two roads, they eventually had to be abandoned. The situation became critical as all field artillery and motor units became congested on the muddy Yueyang-Changsha road. In the meantime, the 40th Division crossed Dongting Lake to seize Yuanjiang, making contact with elements of the 58th Division at Qiaokou.
On June 11, the 40th Division successfully took control of the Yiyang area, while the 34th Division bypassed the Tamoshan Range and launched an attack towards Yuelu Mountain and Fengshupu. The 68th and 116th Divisions bypassed Changsha and moved forward towards Guanqiao, Changlingxiang, and Yisuhe, and the 3rd and 13th Divisions advanced towards Liuyang, facing significant resistance in the region. Despite this, Liuyang fell on June 14, after which the 13th Division proceeded towards Liling. Finding himself completely surrounded, Xue Yue decided to leave Changsha and retreat towards Liling. In the earlier three battles of Changsha, the Chinese had managed to defend the city and counterattack from the flanks; however, both the western and eastern flanks had now fallen to the Japanese, leaving the defenders with no choice but to withdraw.
Now I want to take a short detour. Since mid-1943, the Americans had been constructing airfields in India, Ceylon, and China to house 16 squadrons of B-29 Superfortress Very-Long-Range heavy bombers under Brigadier-General Kenneth Wolfe's 20th Bomber Command. As part of Operation Matterhorn, these bombers were assigned to target locations in Japan, Manchuria, Korea, Formosa, Indochina, and the Dutch East Indies. A key target was the Japanese steel industry, which relied on a few coke plants situated in Kyushu, Manchuria, and Korea—within reach of the B-29s stationed in Chengdu. Before launching an attack on Japan, Wolfe decided to conduct a test combat mission against the Makkasan railway yard facilities in Bangkok, Thailand. On June 5, at 05:45, Brigadier-General LaVerne Saunders led 98 B-29s on a 2,261-mile round trip from India, marking the longest mission of the war up to that point.
Each bomber carried a fuel load of 6846 US gallons and 5 short tons of bombs; three groups carried 500-pound general-purpose bombs while the fourth carried M18 incendiary bombs. The XX Bomber Command wanted to test out the new M18 incendiary bombs and the large number of wooden buildings and freight cars and a small oil facility in the area offered good targets. The resulting 134000-pound takeoff weight was too heavy for the temporary field at Charra, so the 444th Bombardment Group had to stage from the other three fields. The attack was launched at 5:45 local time on 5 June 1944 to avoid high ground temperatures that were bad for the R-3350 engines and to allow the whole mission to be conducted in daylight. Wolfe had suggested a night-time raid, but Arnold insisted on daylight precision bombing.
Only 77 bombers reached Bangkok, conducting a chaotic series of bombing runs between 10:52 and 12:32 due to cloud cover. The bomber's aim was to destroy the Memorial Bridge and a major power plant. They missed and instead knocked down tram lines and destroyed a Japanese military hospital as well as the headquarters of the Japanese secret police. No civilian buildings were damaged, a fact that aroused admiration among the Thai authorities. It was only in 1947 that the Thais discovered the American bombers had been aiming at the Memorial Bridge, almost two and-a-half kilometres away. Following the raid, schools and universities were closed in Bangkok and children moved out of the city for their safety.
Upon returning to India, 42 B-29s had to land at alternative airfields due to low fuel, leading to the loss of five bombers and 15 aircrew fatalities. Despite the setbacks, the mission was deemed successful enough for Wolfe to plan a night attack on Japan for June 15. The B-29s began relocating to Chengdu on June 13 to prepare for the strike against the Imperial Iron and Steel Works in Yawata, producing approximately 2,250,000 metric tons of steel annually, or 24% of Japan's steel output.
On June 15 at 16:16, Saunders led 68 B-29s on a 3,182-mile round trip to Yawata. Although some bombers crashed during takeoff, 47 reached the city and attacked for nearly two hours starting at 12:28. Only forty-seven of the sixty-eight B–29s launched hit the target area: one crashed en route, six jettisoned their bombs because of mechanical difficulties, and seven bombed secondary targets or targets of opportunity. Only 15 American aircraft visually aimed their bombs, as Yawata was obscured by darkness and smoke, with 32 others bombing via radar. Two more B-29s targeted Laoyao harbor, while five attacked other nearby targets. In total, 107 tons of bombs were dropped during the raid.
While returning to Chengdu, three additional B-29 bombers were lost in China. In total, seven B-29s and 55 crew members were lost by the Americans, who managed only to inflict minor damage on Yawata. However, this marked the first attack on the Japanese home islands since the Doolittle raid in April 1942, signaling the start of the strategic bombing campaign against Japan. This raid caused panic in Japanese society, prompting Tokyo to pressure Yokoyama to quickly conquer Changsha and then target the B-29 airfields in central China. As a result, on June 16, the 58th Division launched its assault on Changsha, with the 34th Division also attacking Yuelu and Fengshupu. Changsha fell two days later, leading to the collapse of Chinese resistance in the area. By June 22, Liling and Pingxiang were also captured, allowing the Japanese to gain control over the Jiangxi-Zhejiang railway. Upon hearing of the defeat at Changsha, the Allies worried about the role of Kuomintang forces during Operation Ichi-Go. President Roosevelt proposed placing the entire Nationalist Army under General Stilwell, a suggestion that infuriated Chiang Kai-Shek and was quickly rejected, “Due to our errors in Henan and Changsha, the prestige of our nation and our army, including that of the military command, has been questioned. The foreigners haven’t respected neither our combatants nor our commanders. This offense is more intolerable than the Japanese occupation of our homeland by force of arms.” Meanwhile, Yokoyama's next target was Hengyang to the south, where he planned to encircle the city using the 116th and 68th Divisions while the 40th Division secured Xiangxiang to the west. To the east, the 3rd and 13th Divisions would advance beyond You to secure Leiyang, with support from the 27th Division. The 216th Regiment was set to move upstream along the Xiang Jiang to attack Hengyang from the northeast.
Meanwhile, in Henan, General Uchiyama continued his offensive by capturing the Hotsin Airdrome on May 30 and occupying the towns of Lingbao and Wenxiang by June 11. However, the Chinese forces managed to regroup, ambush, and counterattack the Japanese troops, reclaiming the recently lost towns and ultimately forcing the Japanese to retreat from Loyang and other towns by June 15. Nonetheless, the railway remained under Japanese control and was further reinforced with the capture of Runan and Shangcai on June 16.
Back in Hunan, the second phase of Yokoyama's offensive got off to a strong start as the 40th secured Xiangxiang, trapping many retreating Chinese soldiers and compelling them to surrender. Meanwhile, the 68th and 116th moved quickly toward Hengyang, with the 68th occupying Hengyang airfield on June 26 and the 116th reaching the sector northwest of Hengyang the next day. On that day, the 68th also maneuvered around the city, crossing the Xiangjiang River to launch an attack on Hengyang from the southwest.
Both divisions commenced their assault on Hengyang, but the strong Chinese fortifications held by the well-prepared defenders proved impenetrable. The attackers faced a shortage of ammunition and were further challenged by General Chennault's B-25s, P-40s and P-51s, who bombed and strafed the besiegers. As a result, Major-General Fang Xianjue's 10th Army repelled all Japanese assaults by the end of June. The heavy Japanese losses during these attacks, including severe injuries to Lieutenant-General Sakuma Tameto, compelled Yokoyama to suspend the attacks on July 2 until his artillery could support the siege. Yet that will be all for the China front for today as we are now heading over to Biak.
After General Fuller was relieved on June 15th, General Eichelberger assumed command and decided to follow General Doe’s plans for the June 16th attack. The 186th Infantry's unit began attacking eastward along the ridge shortly after 9:00. Company E led, with the 2d Platoon on the ridge, the 3d Platoon in flats 100 yards to the north, and the 1st Platoon 100 yards beyond the 3d. The 2d Platoon quickly found itself in a maze of Japanese positions and was halted by Japanese automatic weapons fire. The 1st Platoon of Company G thereupon moved up on Company E's right and began advancing along the southern slope of the low ridge. Together, the two platoons continued eastward against slackening resistance. They cleared innumerable enemy slit trenches, foxholes, and bunkers, destroyed several machine guns of various calibers, and at 10:50 reached the lines of the 3d Battalion, 162d Infantry. The task of closing the ridge line gap was completed in less than two hours, many of the previous Japanese defenders apparently having withdrawn north into the West Caves the preceding night.
The Americans also moved northeast but encountered heavy resistance from enemy machine-gun and mortar fire. After intense artillery support, the battalion regrouped and attacked again in the afternoon, reaching the western limits of the West Caves positions. However, concerned about a possible counterattack on his left flank, Doe decided to pull his forces back to the low ridge while Haney's 2nd Battalion took over from the 2nd Battalion, 186th Regiment. The 2nd Battalion, 186th Regiment could look back on the day's operations with a good deal of satisfaction. It had closed the gap on the low ridge; it had located the western limits of the enemy's West Caves positions; it had discovered that more Japanese troops were located north of the enemy encampment area both along the main road and on ridges west and northwest of Hill 320; it had eliminated most of the machine-gun nests and rifle pits in the encampment area and many of those on high, forested ground near that bivouac; it had destroyed many Japanese automatic weapons and rifles; and it had killed at least 65 Japanese. The battalion in turn lost 15 men killed and 35 wounded. There had been only local patrolling by the rest of the units in the forward area during the day, for the 1st Battalions of the 162nd and 186th Regiments had been kept in place by American artillery and mortar fire which supported the operations of the 2nd Battalion, 186th Regiment.
On June 17, after identifying the western limits of the West Caves, Doe instructed Newman's 1st Battalion to advance northwest to high ground while Haney's 1st Battalion moved south and southwest towards the West Caves. Facing strong opposition, the 162nd Battalion, supported by tanks, managed to eliminate several pillboxes before being halted around midday. At the same time, the 186th Battalion approached the high ground from the east and joined forces with Haney's Company C, which had just cleared the final major enemy position on the hill. The Americans then continued their westward attack but made only modest progress by nightfall. With the high ground overlooking the West Caves secured, Doe planned to launch a coordinated attack on the strongpoint the following day. However, on June 18, Eichelberger changed his plans due to dissatisfaction with the progress of the operation. Instead, the 162nd and 186th Regiments reorganized for a coordinated attack, with Newman assigned to attack the rear of the West Caves position while the 3rd Battalion, 163rd Regiment gathered near Hill 320 to block enemy reinforcements.
The main effort was to be made by the 186th Infantry, the 2d and 3d Battalions of which were to attack from the southwest and west while the 1st Battalion struck from the east. The 162d Infantry would hold its positions. An egg-shaped terrain feature on the low ridge 1,000 yards northeast of Borokoe Drome and on the left flank of the 186th Infantry's prospective line of advance was to be seized for flank security and as a line of departure for subsequent attacks north and northeast. On 18 June only local patrolling was undertaken, while the bulk of the troops rested or redeployed in preparation for the attack on the 19th. The egg-shaped feature was secured against no opposition and a few Japanese stragglers along the low ridge in the area were mopped up. The regiment was to advance east from the egg-shaped protrusion of the low ridge with the 2nd Battalion leading, two companies abreast. The 3rd Battalion was to follow the 2nd, and the 1st Battalion would start moving northwestward once the other two had begun moving east. The attack, which was to begin at 6:30 on the 19th, would be supported by the 121st, 167th, 205th, and 947th Field Artillery Battalions, Company D of the 641st Tank Destroyer Battalion, and ten tanks of the 603d Tank Company.
Furthermore, the 34th Regiment was deployed to relieve the 186th west of Mokmer Drome, prepared to take over Borokoe and Sorido Dromes as per Eichelberger's orders. On the morning of June 19, following intense artillery preparation, Eichelberger's offensive began, with Newman's 2nd and 3rd Battalions attacking east and then northwest against light rifle fire and eventually reaching a rugged, heavily-forested coral ridge west of Hill 320 by midday. Around noon, Newman's 1st Battalion started clearing the southern extension of the coral ridge line, successfully advancing through the Japanese encampment area up the road to the 2nd Battalion's position by late afternoon. Facing minimal resistance, the 186th Regiment surrounded the rear of the Japanese in the West Caves, preventing reinforcement or escape. Eichelberger's plans for the next day involved the 186th continuing its operations in the Hill 320 area and the western ridges, while the 162nd attacked the West Caves and the 34th advanced towards the airdromes. On the morning of June 20, Haney's 1st Battalion, supported by two tanks, attacked the West Caves, facing lighter resistance initially but ultimately being halted by heavy Japanese fire. At the same time, Newman's troops extensively patrolled and discovered the Teardrop position, while the 34th Regiment quickly took control of the Borokoe and Sorido Dromes and Sorido village, facing minimal opposition.
During the 1st Battalion, 162nd Regiment again moved up to the West Caves on June 21 and sent patrols out to clear Japanese riflemen from brush and crevices on hillocks north and northwest of the caves. The patrols, actually flamethrower teams supported by riflemen, accomplished their mission without much difficulty while the rest of the battalion, again covered by two tanks from the 603rd Tank Company, surrounded the sump depressions. The infantry and tanks concentrated on the most westerly of three large sinkholes comprising the West Caves. The tanks fired into cave entrances; the infantrymen lobbed hand grenades into holes and crevices within reach; and all Japanese observed were quickly killed by rifle fire. But the battalion was unable to force its way into the main entrance to the underground caverns. Fire into this entrance was also ineffective, for the opening was shielded by stalagmites and stalactites. Engineers poured the contents of five gasoline drums into the cavern through crevices or seepage points found on the surface of the ground. Flamethrowers then ignited the gasoline and the 1st Battalion withdrew to await developments. There were no immediately apparent results and, since it was believed that the West Caves were still strongly held, the battalion did not attempt to send any more men into the entrance. In the late afternoon the unit again pulled back to its bivouac area.
The attacks during the night of June 21-22 had apparently resulted from a decision on the part of Colonel Kuzume to acknowledge defeat. In an impressive ceremony in the West Caves, Colonel Kuzume, surrounded by his staff, burned the colors of the 222nd Regiment and, according to some American reports, disemboweled himself in the tradition of the Samurai. Japanese reports of the Biak action state that Colonel Kuzume did not die then but was killed in action or committed suicide some days later. Whatever the cause and date of his death, on the night of June 21-22 Colonel Kuzume had instructed the forces remaining in the West Caves to withdraw to the north and west. Many of the remaining troops of the 1st and 2nd Battalions, 222nd Regiment, who had originally held the low ridge north of Mokmer Drome, had already been killed or had moved north, and most of the Japanese killed by the 186th Regiment during the night of June 21-22 were identified as members of the 221st Regiment, elements of which had been included in the reinforcements sent to Biak after Z Day.
At 4:00 am on June 22, the Japanese launched another attack, relying on stealth, hand grenades, and bayonets. Japanese poured out of the caves and rushed northwest up the road toward the lines of the 186th Infantry, attempting to escape to the west or north. At 2100 Japanese infantry, supported by light machine guns and light mortars, hit the southeast flank of the American regiment. When the Japanese were about fifty yards away, the 186th Infantry's .50-caliber machine guns opened fire and broke up the attack. Undaunted, the Japanese made another break-through attempt about midnight, this time supported only by light mortars. Machine guns, both .50- and .30-caliber, aided by Company G's 60-mm. mortars, forced the enemy to withdraw for a second time.
This final assault was so fierce that the enemy reached the 186th's foxholes, resulting in hand-to-hand combat across the regiment's southern flank. Mortar fire eventually scattered the disorganized enemy, though small groups of Japanese soldiers continued to mount sporadic attacks until dawn. Haney’s 1st Battalion continued to face enemy resistance at the West Caves; however, after dropping two 500-pound TNT charges into one of the cave entrances, the Americans initially reported the caves cleared. This assessment proved premature when another small group of Japanese attempted to breach the 186th Regiment's lines later that night.
On the following morning, Haney’s 1st Battalion set up a permanent camp around the various caves and indentations, continuing their search through the area. Although the remaining Japanese troops were trapped in a hopeless situation, they managed to hold their ground. It wasn't until the afternoon of June 25 that any soldiers managed to access the caves, but without making any deep inroads. It wasn't until June 27 that patrols reached the innermost parts of the West Caves. The stench of rotting Japanese bodies was revolting, and the sight nauseating. The entire cave area was strewn with Japanese bodies or parts of bodies. One gruesome area had apparently been used as an aid station and another possibly as a butcher shop for cannibalistically inclined survivors of the carnage since June 18. Three more Japanese were killed in the caves during the day, and large quantities of equipment and documents were found. Because of the advanced stage of decomposition of many of the dead, a complete count of Japanese bodies could not be made, but before overpowering odors drove the patrols out of the caves 125 more or less whole bodies were counted. This was considered a minimum figure, for no estimate could be made of the numbers of Japanese represented by separated arms, legs, or torsos and it was impossible to guess how many Japanese had been sealed in smaller caves or crevices by artillery and mortar fire or by explosions of TNT and Japanese ammunition within the caves.
With the suppression of Japanese cave positions near Mokmer airfield, the strip was finally operational, and P-40s and B-24s started using it from June 22. Between June 22 and 24, the 186th Regiment also took down some Japanese positions northwest of its perimeter. By June 25, Colonel Newman managed to subdue the Teardrop position. Despite lacking supplies and water, some Japanese managed to flee westward, where the 34th Regiment would eventually clean up the area by the end of June. Over at the East Caves from 7 through 10 June the 4.2-inch mortars of the 2d Platoon, Company D, 641st Tank Destroyer Battalion, lobbed over 1,000 shells into the East Caves area. On the 9th and 10th, tanks in LCT's cruising offshore added their fire, and on the latter day the 205th and 947th Field Artillery Battalions swung into action against the East Caves. Bombardments by artillery, mortars, tanks, and destroyers continued from 11-13 June, but the Japanese still managed to deny to the HURRICANE. Task Force the use of the coastal road during much of the period. In between artillery and naval gunfire concentrations, elements of the 3d Battalion, 163d Infantry, probed more deeply into the Japanese positions from the north and northeast and located the north flank of the main enemy defenses. By noon on the 13th, the combination of American fire and infantry action had succeeded in silencing enough of the Japanese fire so that truck convoys could safely use the coastal road without interruptions for the first time. Infantry patrolling and all types of bombardment continued from 14 through 23 June, but the Japanese still occasionally harassed truck convoys along the coastal road. On the 23d or 24th (the records are contradictory) there was undertaken a series of aerial bombardment missions which are among the shortest on record. Fifth Air Force B-25's, based on Mokmer Drome, took off from that field to skip-bomb the East Caves. Although most of the bombs missed the main sump holes, the air missions did cause many explosions and started a number of fires in the East Caves. For a few days, at least, almost all the enemy fire was silenced.
On 27 June Company E, 542d Engineer, Boat and Shore Regiment, started to construct a jetty near Mokmer, and in connection with this mission began working a gravel pit at the base of the ridge northwest of the village. Japanese mortar and rifle fire from the East Caves impeded the latter work and on 29 June 4.2-inch mortars and tanks had to be moved back into the area to shell the caves and protect the engineers. Within three days the mortars fired over 800 rounds into the caves. The engineer company, borrowing bazookas from an infantry unit, sent its own patrols into the caves, and Company I, 163d Infantry, sent patrols back into the area from the north. On 30 June the 205th Field Artillery Battalion sent one gun of Battery C to a position near Mokmer village to place about 800 rounds of smoke and high explosive shells into the caves. Light harassing fire continued, however, and on 3 July elements of Company E, 542d Engineer Boat and Shore Regiment, moved into the caves under cover of tank fire from the base of the ridge. Some tunnels were sealed shut, twelve Japanese were killed, and two light machine guns were captured. Almost simultaneously, Company E, 163d Infantry, pushed into the caves from Mokmer village. Neither the engineer nor the infantry unit met as much resistance as had been anticipated. Patrolling throughout the caves was continued on the 4th and 5th, and on the latter day a platoon of Company E, 163d Infantry, entered the larger sump holes, where were found many automatic weapons, mortars, rifles, all types of ammunition, food, clothing, cooking utensils, and pioneer equipment. The next day loudspeakers and interpreters were sent into the caves to persuade the few remaining Japanese to surrender. Only ten Japanese, of whom eight were killed, were seen in the area. The Japanese who had lived uninjured through the heavy bombardments since 7 June had evacuated the East Caves. The few Japanese left alive in the East Caves after 6 July were still capable of causing some trouble. On 15 July six souvenir hunters of the Royal Australian Air Force (elements of which were staging through Biak for operations farther west) were killed near the caves. Tanks and infantry were sent into the area to mop up the remaining Japanese and recover the Australian dead. On the 16th and 17th, three badly mutilated bodies of Australian airmen were found and two Japanese machine gun nests were wiped out. On the 20th the infantry and tanks returned to the caves, found the other Australian bodies, and eliminated the last enemy resistance.
Meanwhile, the determined and resourceful defenders of the Ibdi Pocket resisted repeated attacks from the 2nd Battalion, 163rd Regiment and ongoing artillery barrages. By the end of June, the Japanese had been pushed into a 600-yard-square area, with American patrols continuing the cleanup in July. Through the use of bazookas, flamethrowers, tanks, and artillery, the remaining Japanese were gradually confined to an even smaller area until the pocket was cleared on July 28.
The American forces would then mop-up the remainder of the island up to August 20, accounting for a total of 4700 Japanese dead and 220 captured since the start of the battle. Total American casualties were an estimated 400 killed, 2000 wounded, 150 injured in action and 5 missing. Additionally, there were 7234 non-battle casualties due to sickness, many of whom were returned to duty.

Operation Ichi-Go was continuing its horror show deeper into central China. B-29 Superfortresses are arriving to the scene, first from India and China, but as the Pacific Island hoping campaign makes more and more progress, soon they will be lifting off from airfields much closer to the Japanese home islands.

- 135 - Pacific War - The Great Marianas Turkey Shoot, June 18-25, 1944
1 jul· The Pacific War - week by week
Last time we spoke about the Invasion of Saipan, Tinian and Guam. The Japanese mistakenly believed that the Americans were preparing for a decisive battle near New Guinea, not realizing the real target was Saipan. The US assembled a large fleet for Operation Forager, aiming to capture Saipan, Tinian, and Guam, advancing the US strategy to establish strategic airfields to hit Tokyo. Japanese defenses were ill-prepared, with shortages of ammunition and inadequate inland defenses. The Americans hit Saipan with extensive air and naval bombardments, neutralizing Japanese positions, and faced stiff resistance during landings but ultimately secured a beachhead. The 23rd Marines of Colonel Louis Jones, advanced through Charan Kanoa and secured Mount Fina Susu despite significant losses. Heavy artillery pinned them down at the O-1 Line, leading Jones to reposition his forces. Casualties mounted on both sides as American forces fought to secure the beachhead and push inland.
This episode is the the Great Marianas Turkey Shoot

Before his death Admiral Yamamoto instilled a sort of mind virus into the Imperial Japanese Navy. To be honest, the virus was a pre war doctrine, laying around ever since perhaps the First-Sino Japanese War of 1894-1895, but Yamamoto certainly focused attention more so upon it. The infamous decisive naval battle. The event that could turn the tide of the war, to bolster Japan’s poker hand for peace negotiations. If Japan could simply knock out a enormous sum if not the entire strength the American Pacific fleet, something extremely unrealistic by this point of the war, but if they could, would America not reconsider settling this all up at the peace table? It had been the strategy of not just the IJN but for the Japanese military as a whole. Japan would never be able to win a war of attrition with the US, but they could make them pay so dearly, perhaps the Americans would just sue for peace. This idea consumed Yamamoto, leading to the disaster at the Battle of Midway. After the Guadalcanal Campaign, Japan lost the initiative, they retreated behind an inner perimeter. Henceforth the IJN scoured over the actions of the American navy, looking for any opportunity to unleash their full might down upon a significant American naval force. So many times the American navy eluded them, but here, with the invasion of Saipan, the IJN felt the decisive naval battle had finally come.
Admiral Turner and General Smith's American forces had just successfully invaded Saipan, establishing a beachhead with some challenges by June 17. This incited a strong Japanese response, as Admiral Toyoda initiated Operation A-Go, the IJN’s strategy for a decisive battle that could potentially win them the war. Following Admiral Koga’s Plan Z, Toyoda's A-Go involved Admiral Kakuta's land-based aircraft providing early warning and reconnaissance, aiming to neutralize one third of the enemy carriers before Admiral Ozawa’s carriers completed the destruction of the enemy fleet with large-scale daytime air attacks, operating beyond the enemy's aircraft range. Additionally, Toyoda planned a nighttime surface engagement where enemy screening forces would be targeted by massed torpedo attacks. On June 16, at 9:00, the First Mobile Fleet departed the Guimaras and headed to the northeast. At 5:30pm, the Japanese fleet entered the Philippine Sea through the San Bernardino Strait. Admiral Ugaki’s battleships Yamato and Musashi were not with the main body, but were proceeding independently through the Philippine Sea with two heavy cruisers, a light cruiser and five destroyers to join with Ozawa. Once into the Philippine Sea, Ozawa headed southeasterly. At about 5:00 on the 16th, Yamato and Musashi joined with the First Mobile Fleet. The Japanese began to refuel which was not completed until 10:00 on the 17th.
In response, Admiral Spruance directed Admiral Mitscher’s Task Force 58, strengthened by Admiral Lee’s battleships and Turner’s cruisers and destroyers, to remain positioned west of the Marianas, prepared to counter any IJN attack. On June 16, Mitscher continued strikes against Guam and Tinian. Several Japanese aircraft were destroyed on the ground and in the air, but their airfields remained usable. The following day saw an increase in Japanese air activity. A small strike flown from Truk, five torpedo bombers and one J1N1-S night fighter attacked a transport group east of Saipan at 5:50pm. Three Japanese aircraft were claimed as destroyed, but a torpedo hit the small landing craft LCI-468 that later sank. On June 18th, the Japanese mounted a larger raid, this time from Yap Island. This operation featured 31 Zeros, 17 Judys and two P1Y twin-engined bombers. Combat Air Patrol did not intercept this group before it attacked shipping off the landing beach at Saipan that resulted in damage to an LST. The attack group then encountered the American escort carrier groups and attacked them at dusk. Two escort carriers were nearmissed and Fanshaw Bay was hit by a bomb which penetrated to the hangar deck. The carrier was forced to retire for repairs. As usual, Japanese aviators over-claimed, stating that three or four carriers from Task Force 58 had been hit.Furthermore, Admirals Lockwood and Christie's submarines were tasked with reconnaissance of IJN fleet movements, launching attacks when possible, and rescuing downed aircrews. Since Ozawa’s fleet maintained radio silence and operated beyond the reach of American search planes, the only way to track his movements was through submarines, leaving the Americans mostly uninformed until the battle began.
Unknown to Ozawa and Toyoda, Mitscher's carrier aircraft had already disabled Kakuta's land-based air power in the area, which significantly weakened a major part of A-Go. Additionally, the Americans, who had acquired Plan Z on April 3, were prepared for the critical carrier battle, although they were hesitant to engage in nighttime combat. Meanwhile, on June 18, the 2nd and 4th Marine Divisions began their attacks at 10:00 a.m. The 4th Marine Division attacked toward the east coast with three regiments abreast: 25th Marines on the right, 24th Marines in the center, and 23rd Marines on the left. The 3rd Battalion, 24th Marines, remained attached to the 23rd Regiment. Good progress was made by the 24th and 25th Marines, although the former sustained an attack at 10:15 by two Japanese tanks which surged to within 350 yards of the front lines. The situation for a while was alarming: American tanks had departed for rear areas to refuel and rearm so that only bazookas were immediately available for anti-tank defense. Though the 24th Marines’ Weapons Company was immediately alerted, it arrived too late to participate in the fight. The enemy tanks were finally chased by bazookas and artillery, but not before they had sprayed the area, causing 15 casualties with machine-gun and small cannon fire. A portion of the O-3 line was reached by the 24th and 25th Marines during the day, placing the latter along the coast of Magicienne Bay. This healthy gain severed the island's southern portion, including Nafutan Point, from the remainder of the island. To maintain the momentum of the attack and avoid the long delay of a mopping-up process, the 24th Marines by-passed the southern extremity of a heavily defended cliff line running north and south through its zone of action. However, since the direction of attack for the division would soon Swing north through the by-passed area, it was necessary to secure the cliff line. This mission was assigned to the division reserve, 1st Battalion, 25th Marines. This, the unit’s first experience with cleaning cave positions, proved a sIow, unpleasant and dangerous task. Rather than a coordinated move, the task took the form of a series of small, separated actions, each employing groups of four or five men.
At 7:30, the 3rd Battalion, 24th Marines, relieved Haas’ 1st Battalion on the division’s left wing and commenced the move on O-2, which would serve as the line of departure. As will be seen, however, events of the day prevented the regiment from reaching this line. Organizational readjustments within the 23rd Marines included the attachment of the 3rd Battalion’s rifle companies and 81mm mortar platoon to Dillon’s 2nd Battalion and formation of a composite battalion from the 1st Battalion and the 3rd Battalion Headquarters. The latter unit would support the attack of the other two battalions from positions on Mt. Fina Susu. Machine-gun fire stopped the 23rd Marines’ left elements after an advance of 200 to 250 yards. Most of this fire came from a clump of trees to their front, but a definite location of enemy weapons was impossible. Frequent barrages of Japanese mortar fire hampered efforts to spot the enemy, and the attack faltered. At this juncture, Cosgrove’s composite battalion was committed on the left of the 3rd Battalion. 24th Marines, in an attempt to retain the impetus, and the attack again moved forward. But the advance was slow. By 5:15, the 23rd Marines had moved to a line about 400 yards short of O-2. Prior to darkness, 23rd Marines’ patrols were dispatched to the east. On the right, these patrols reached O-2, but on the left machinegun fire denied movement as far as O-2. Colonel Jones, the 23rd Marines’ commander, requested permission from General Schmidt to withdraw to more favorable ground for the night. General Schmidt approved, and the 23rd pulled back to a position about 400 yards east of Lake Susupe, breaking contact with the 2nd Division.
The 23rd Marines emerged from the swamps, the 24th Marines reached the base of Hill 500, and the 25th Marines progressed to Magicienne Bay, effectively dividing the island. General Smith's soldiers also captured the Aslito Airfield, with the 165th and 105th Regiments securing Cape Obiam and the area south of the field. This isolated numerous Japanese forces in the north at Nafutan Point. Concurrently, General Saito was shifting his remaining troops to the Garapan-Mount Tapotchau area, facing relentless artillery, naval, and air attacks that left the Japanese in a dire situation.
The chief of staff of the 31st Army, General Igeta, drafted a message on the morning of June 18th to the commanding general at Yap Island and the chief of staff in Tokyo. In it he summarized the situation as he saw it and, in the process, revealed how very little he knew of what was taking place. Not that the general was caught in the bog of apathy, nor was he too frightened or lazy to find out what was going on; it was simply impossible for him to penetrate the shroud of obscurity resulting from ruptured communications in the vast area over which the action was taking place. As such, he erroneously reported that the 43rd Division HQ “underwent an enemy attack this morning and the division CO died along with his staff officers.” In another dispatch later in the day, Igeta corrected his error in regard to the division commander’s death, reporting that General Saito was “all right, but that his staff officers were wounded.” He also added that “the secret documents in custody of the 31st Army Headquarters… were completely burned at 1830 of 18 June…” Recognizing the desperate circumstances, Prime Minister Tojo sent a fatalistic message to the garrison, despite reinforcements en route. “Have received your honorable Imperial words. By becoming the bulwark of the Pacific with 10000 deaths; we hope to acquire Imperial favor.”
Reports indicated that Ozawa's mobile fleet was approaching the Marianas and expected to arrive on June 19. When Spruance finally received the spotting report from Cavalla, this prompted a decision that turned out to be the most important of the battle. Assuming that the report from Cavalla was Ozawa’s main force, and assuming it would continue at a speed of 19 knots to the east, Spruance’s staff calculated that the Japanese would still be about 500nm from TF 58 at 5:30 on the 18th. This placed the Japanese well out of range of American searches or strikes. The only way to alter this situation was to steam TF 58 to the southwest toward the contact and plan to locate and engage the Japanese during the afternoon of the 18th. Mitscher advised the aggressive option of steaming to the southwest to close the range on Ozawa’s force. He wanted to launch afternoon strikes to locate and possibly attack Ozawa and even advocated a nighttime surface engagement. While this offered the possibility of opening the battle on terms set by the Americans, there were several problems with it in Spruance’s calculating mind. The first was that TF 58 was not yet concentrated; TGs 58.1 and 58.4 were not due to link up with the other two task groups operating west of Saipan until 1200 on the 18th. If he allowed Mitscher to take off to the west, it would only be with two task groups. Since the Japanese possessed longer-range strike aircraft, this offered Ozawa the chance to attack TF 58 and defeat it piecemeal. As for the prospects of a night engagement, both Spruance and Lee declined that possibility.
In response, Spruance adopted a cautious approach, instructing Mitscher to gather his carrier groups and redirect them toward Saipan. In a last effort to change Spruance’s mind, Mitscher sent him a message at about 11:30pm and proposed a course change to the west at 1:30am in order to position TF 58 to launch a strike against the Japanese carrier force at 5:00am. At 12:38am on the 19th, Spruance sent a message rejecting the proposal. The die was finally cast for a defensive battle on June 19.Spruance's priority was to safeguard the invasion force rather than eliminate the Japanese fleet.
At 6:00am on the 18th, Japanese search floatplanes from the First Mobile Fleet spotted six carriers from TF 58. In the afternoon, seven aircraft from Carrier Division 1 flying out to 420nm spotted TF 58 after its 1200 rendezvous. The first report was issued at 3:14pm and included detection of an American task group with two carriers. A second aircraft sighted a task group with an “unknown number of carriers” at 4:00 and later issued another report at 1710 which identified two task groups, each with two carriers. These were within strike range, but Ozawa elected not to launch an immediate strike since his pilots were so inexperienced in night flying. Nonetheless, Rear-Admiral Obayashi Sueo of the 3rd Carrier Division boldly ordered the launch of 67 aircraft from the carriers Zuiho, Chitose, and Chiyoda, hoping to surprise the Americans. However, when he learned of Ozawa’s decision, Obayashi reluctantly called off his strike. Ozawa had correctly assessed that the enemy would hold its position near Saipan, allowing him to maintain his own position without fearing an American attack. With this understanding, he changed course southwest to maintain the distance, while Admiral Kurita’s Vanguard Force moved east, and Forces A and B shifted south. At 03:00 on June 19, all three forces turned northeast and increased their speed to 20 knots. Ozawa executed his plan flawlessly, positioning himself to launch significant attacks against the unsuspecting Americans the next morning. His only misstep was breaking radio silence at 20:20 to coordinate the decisive operation with Kakuta, who consistently misrepresented the true condition of his air forces while giving overly optimistic reports of successes by his aviators. As a result, an American station intercepted the transmission and geo-located it accurately. Once the mobile fleet reached strike positions, the Japanese began launching search aircraft, sending 16 floatplanes at 04:45 and another 14 planes about 30 minutes later. Although they lost seven scouts, the Japanese were able to spot the northern elements of Task Force 58 and the picket destroyers deployed ahead by 7:00.
Starting at 05:30, Mitscher's combat air patrol engaged Japanese aircraft from Guam, which were unsuccessful in bombing destroyers. At 6:30am, American radar detected Japanese air activity over Guam and four Hellcats were sent to investigate. At 7:20am, these arrived and found themselves in the middle of many Japanese aircraft taking off. More Hellcats rushed in and, beginning at 8:07am for the next hour, there was constant combat over and near Guam. Up to 33 American fighters were involved, and they claimed 30 fighters and five bombers. The Americans claimed to have destroyed 30 aircraft, successfully hindering Kakuta's support for Ozawa's decisive battle. However, with the return of Japanese floatplanes, Ozawa was preparing to launch his first strike, deploying 69 aircraft: 16 Zero fighters, 45 Zeros with bombs and eight Jills with torpedoes at 08:30 under Obayashi's command. Fortunately for the Americans, radar warnings enabled Mitscher to dispatch every available Hellcat for interception. At 10:23am, launching of every available Hellcat from TF 58 began as the force headed east into the wind. The American carriers cleared their decks and all airborne bombers on search and patrol missions were instructed to clear the area. This allowed the fighters to return as necessary to rearm and refuel. The goal was to keep as many fighters in the air as possible to intercept incoming threats. The Hellcats had reached their interception altitudes of between 17,000 and 23,000ft when at 10:35am they spotted the incoming Japanese aircraft identified as two groups of strike aircraft with escorting Zeros on each flank. The first American fighters on the scene were Hellcats from Essex. Lieutenant Commander C. Brewer of Fighter Squadron 15 VF-15 led them. The escorting Japanese fighters did not protect the bombers and the bombers scattered making them easy to pick off. Brewer claimed four aircraft, and his wingman claimed another four. In all, VF-15 pilots claimed 20 Japanese aircraft. Joining the Hellcats from Essex were others from Hornet and Bunker Hill as well as from five light carriers for a total of 50 Hellcats. Altogether, some 25 out of the 69 Japanese aircraft in this raid were accounted for by this initial interception. In return, three Hellcats were lost in combat and a Bunker Hill Hellcat was lost when it ditched on its way back to its carrier. The remaining Japanese aircraft continued their approach but were intercepted by Bunker Hill's Hellcats, which claimed another 16. Only around 28 Japanese planes remained and made minor attacks on Admiral Lee's group. Two targeted battleship South Dakota, with one scoring a direct bomb hit at 10:49, though causing minimal damage. Another narrowly missed heavy cruiser Minneapolis, while another almost missed cruiser Wichita. The Japanese reported losing 42 aircraft: eight fighters, 32 fighter-bombers, and two torpedo bombers. Most had been destroyed by Hellcats, with anti-aircraft gunnery from TG 58.7 accounting for the rest. Meanwhile, Ozawa launched his main strike at 08:56, composed of the 1st Division's best-trained pilots from three fleet carriers. This was a large strike designated Raid II from the three fleet carriers of Carrier Division 1 with the best-trained aviators in the First Mobile Fleet. The raid consisted of 128 aircraft – 48 Zero fighters, 53 Judy dive-bombers and 27 Jills with torpedoes. Launching began at 08:56 but was disrupted when at 09:09 Taiho came under attack by American submarine Albacore. The submarine fired six torpedoes at the fast-moving carrier. A last-second glitch in the boat’s fire-control computer made it necessary to fire the six torpedoes by eye. One of Taiho’s aircraft saw the torpedoes headed for the ship and dove into one in an effort to save the ship. In spite of this, one of the torpedoes hit the carrier abreast the forward elevator and created a hole which resulted in flooding. The ship’s forward elevator, which was raised for the launch, was knocked out of alignment and fell several feet. Within 30 minutes, the elevator space was planked over by damage-control personnel and the launch continued. In addition to the aircraft lost from Taiho, eight other aircraft developed engine trouble and were forced to return. More trouble soon followed. When the attack group flew over the Vanguard Force deployed about 100nm in front of the main carrier force, it was engaged by the Japanese ships. This fire was effective enough to shoot down two more aircraft and damage another eight that were forced to return.
This attack and some friendly fire reduced the Japanese force to just 109 aircraft for the largest strike of the day, which was detected by radar. In a swirling action that began at 11:39am, the Hellcats again tore through the Japanese formation. McCampbell claimed three Judys and his wingman two. Other Hellcats joined the fray resulting in about 70 Japanese aircraft being shot down. VF-16 from Lexington claimed 22 Japanese aircraft without a loss; 12 Bunker Hill Hellcats were unable to gain a solid intercept but still claimed five kills, and Hellcats from light carriers Bataan, Monterey and Cabot claimed ten, seven and five, respectively. VF-1 from Yorktown also scored heavily. This still left a number of Japanese aircraft headed for TF 58. Twenty were reported in three groups at 11:45. Most of these made the mistake of attacking the picket destroyers deployed in advance of TG 58.7 or Lee’s battleship force itself. Destroyer Stockham reported being under attack for 20 minutes, but again the ship suffered no damage. Around noon, TG 58.7 came under attack. Two torpedo bombers attacked South Dakota with no success, and two more selected Indiana in the center of TG 58.7’s formation as their target. One crashed into the waterline of the heavily armored ship but caused little damage. Another Jill went after Iowa, but again missed. Alabama was undamaged by two bombs aimed at her. Potentially more serious was a group of six Judy dive-bombers that escaped the Hellcats and proceeded south until running across TG 58.2. Of this group, four selected carrier Wasp for attack. None scored a hit, but one of the bombs detonated overhead which rained down shrapnel that killed one and wounded 12 crewmen. The other two selected TG 58.2’s other fleet carrier, Bunker Hill, for attack at 12:03. They scored two near misses that caused minor fires and other damage, in addition to killing three and wounding 73. Both carriers continued in action. Four of the aircraft were shot down by antiaircraft fire, with the other two landing on Rota and Guam. Finally, six B6N bombers attacked Admiral Reeves’ carriers, but their attacks began at 11:57 and were also ineffective, failing to hit any targets. One missed Enterprise, and another three attacked light carrier Princeton, but all three were destroyed by antiaircraft fire.Thus, Ozawa’s second strike resulted in a significant loss for the Japanese, with 97 of the 128 aircraft not returning to their carriers. His losses totaled 32 fighters, 42 dive-bombers and 23 Jills.
At 5:30, the third group of Japanese scout aircraft took off. This comprised 11 Judys from Shokaku and two Jakes from heavy cruiser Mogami. The aircraft flew 560nm to the east. Two contacts were radioed back to Ozawa. The first, at 9:45, was reported at a position well to the south of TF 58’s actual position. The problem resulted from an uncorrected compass deviation on the search aircraft. This contact was designated “15 Ri” by the Japanese. The second contact, designated “3 Ri”, was reported at 10:00. It was of a task force of three carriers and escorts to the north of TF 58’s actual position, but may have been of TG 58.4.This third Japanese strike designated Raid III by the Americans was mounted by Carrier Division 2. This effort, from Junyo, Hiyo and Ryuho, comprised 47 aircraft including 15 fighters, 25 Zeros with bombs, and seven Jills with torpedoes.
The remaining 20 aircraft saw what they believed to be two battleships but chose to keep searching for carriers. After a failed search, the group eventually attacked the battleships they initially spotted at 12:55 but were intercepted by Hellcats and lost seven aircraft. Nonetheless, the group pressed on and attacked Rear-Admiral William Harrill’s carriers at 13:20. The effort was ineffective with one aircraft dropping a bomb 600 yards from Essex. Ozawa’s third strike had accomplished nothing, but at least 40 of its 47 aircraft survived to return to their carriers.
At 11:00, Ozawa launched his final attack of the day, consisting of 82 aircraft from the carriers Junyo, Hiyo, Ryuho, and Zuikaku of Carrier Division 1. It comprised 30 Zero fighters, ten Zeros with bombs, 27 Vals and nine Judys and six Jills. The planes set off for the new, incorrect southern target and found nothing, causing them to divide into three groups. The largest group of 49 planes headed toward Guam, where the Americans had been periodically discarding their ordnance to neutralize Kakuta’s airfields.
As Ozawa sent his series of strikes against TF 58, Spruance directed Mitscher to keep a number of Hellcats active over Guam to disrupt any Japanese attempt to mount attacks from there. This reflected Spruance’s fear that the Japanese would use Guam as a base for “shuttle bombing” using aircraft from the 1st Mobile Fleet. Before the first Japanese carrier raid, Hellcats encountered airborne Japanese aircraft over Guam. This action continued throughout the day and periodically intensified when TF 58 dive-bombers and Avengers, ordered to the east to steer clear of the air battle, dumped their ordnance on Guam. Before noon, 15 Yorktown and 17 Hornet Helldivers bombed Orote Field on Guam. Another attack was mounted at 13:30 by Dauntlesses from Lexington and Enterprise, nine Avengers from Enterprise and ten Hellcats for escort. The armor-piercing bombs carried by the dive-bombers did little damage, but the Avengers succeeded in cratering the runway. Other attacks continued throughout the afternoon including Hellcats from Bunker Hill strafing Japanese aircraft on the ground and 11 Helldivers from Essex just before 14:00. The price to keep Guam suppressed during the day was steep – six Hellcats and one Helldiver – but the Base Air Force did not support Ozawa’s main attack.
Back over at the carrier action, Ozawa’s first group approaching Guam were picked up by TF 58 radar at 1449hrs. Before long, 27 Hellcats were on the scene. Among these were 12 from light carrier Cowpens, seven from Essex again led by McCampbell, and eight from Hornet. The Hellcats did great execution, shooting down 30 of the 49 Japanese trying to land on Guam. The remaining 19 planes landed but were damaged on the ground and could no longer fly.Another 15 aircraft headed for Rota but changed course to attack Montgomery’s group when they sighted it en route. Six aircraft approached Wasp unmolested until 2:23 when they were engaged by antiaircraft fire just as they were dropping their bombs. Adept maneuvering by Wasp thwarted the aircraft, identified as Judys. Another group of divebombers appeared and split up; two went after Bunker Hill, and one after Wasp. All missed, and of the nine attackers, only one escaped. The final 18 aircraft of Raid IV, including the eight from Zuikaku and ten Zeros with bombs, were returning to their carriers when they encountered two American scout groups consisting of Hellcats and Avengers some 200nm west of Guam.This encounter cost the Japanese six aircraft, but they did gain a measure of revenge when at 3:30 the same group of returning Japanese aircraft encountered and shot down two Bunker Hill aircraft on a search mission. Despite these efforts, none of the American ships were hit during this fourth attack, while Ozawa suffered a significant loss of 73 aircraft.
The situation worsened when the submarine Cavalla spotted Shokaku recovering aircraft at 11:52 and launched six torpedoes. Three torpedoes hit the carrier's starboard side at 12:22, sparking fires in the hangar and causing the ship to list. Soon, the ship came to a halt and was left behind when Carrier Division 1 moved north. At 1310, the fires on the hangar set off a bomb that set off fumes from the cracked forward fuel tank. Large explosions ensued and it was obvious the carrier was doomed. Shokaku sank at 15:01, resulting in the deaths of 1,272 crew members. The light cruiser Yahagi and destroyers Urakaze, Wakatsuki, and Hatsuzuki rescued Captain Matsubara and 570 men. Additionally, a torpedo hit Taiho, cracking the forward aviation fuel tank and turning the IJN’s newest and most heavily protected carrier into a floating bomb.
At 3:32pm, a massive explosion hit Taiho, lifting her flight deck and causing damage to her hull that led to the ship sinking. Despite Ozawa's initial desire to stay with the carrier, he and his team were eventually evacuated by a destroyer. However, 660 members of Taiho's crew perished as the ship sank. The transfer to the Haguro, added to the confusion for Ozawa was the fact that he and his staff were jammed into inadequate facilities aboard heavy cruiser Haguro after they were forced to depart from Taiho. Communications were grossly inadequate; Ozawa admitted later that he should have turned over command to Kurita until he could have moved to a ship with adequate command and control facilities. After the final strike aircraft returned, the Japanese turned northwest at 18:08, preparing to refuel the following day before continuing their attack. In their four strikes, the Japanese had launched 373 aircraft; of these 243 were lost. Added to these losses were another 50 from Guam, nine when Shokaku went down, and another 13 from Taiho to bring the total to 315. Some 296 Hellcats had been engaged during the day in combat, and only 14 were lost in combat with another six recorded as operational losses. The lack of sufficient training and experience among Japanese aircrews was evident, as seasoned American pilots compared the battle to “an old-time turkey shoot down home.” As a result of the significant losses inflicted on Japanese aircraft by American forces, the aerial portion of the Battle of the Philippine Sea was known as the Great Marianas Turkey Shoot. In the war upon the land, after an uneventful night, the 2nd Marine Division conducted patrols as Generals Schmidt and Smith focused on securing the rest of southern Saipan.
Although the 4th Marine Division's assault was postponed due to their need to disperse a sizable Japanese group near Tsutsuran village, the 27th Division pressed forward in the morning with the 165th Regiment swiftly reaching Magicienne Bay. In contrast, the 105th advanced more slowly through challenging terrain, resulting in a gap between the two regiments and requiring the 165th to extend its lines to maintain contact. Further north, Colonel Jones' 23rd Marines succeeded in advancing close to Hill 500 after intense artillery bombardment, but were compelled to withdraw about 400 yards to protect their vulnerable flank. At this stage, Brigadier-General Arthur Harper's Corps artillery had arrived on the island, offering essential reinforcement to the division's artillery units. By the end of the day, Schmidt's division realigned its regiments and shifted north. The most vicious action of the night occurred in the sector occupied by the 2nd Battalion, 24th Marines. Starting at about 3:50am and lasting until daylight, an enemy force of approximately 75 attacked the Marines with grenades and bayonets. In the close-in fighting that ensued, 11 Marines were wounded, but, in the process, the enemy attack was broken. By daylight, many of the attackers were sprawled forward of the Marines’ foxholes, the rest had taken to their heels. Meanwhile, Admiral Mitscher, having retrieved all his aircraft, set a westerly course and increased speed to 23 knots in an attempt to catch up with the enemy. However, on June 20, his usual morning search found no results. The Japanese also maintained radio silence during the day, with no new intelligence obtained by American submarines or PBM flying boats based in Saipan. In the afternoon, a successful search finally established contact, prompting Mitscher to prepare for a bold night strike against an enemy fleet beyond the maximum strike range.
Meanwhile, the plan to refuel the 1st Mobile Fleet on June 20 fell through amid confusion, prompting Ozawa to abandon the attempt after noon. He transferred to the Zuikaku and restored communications, discovering the extent of his aircraft losses. Ozawa’s hope that he could continue strikes was buoyed by reports from Kakuta that some of Ozawa’s aircraft had landed on Guam and the prospects that additional land-based aircraft reinforcements would flow into the area. The only concession he made was to move his next attack until the 21st.
However, at 16:45, Ozawa's reconnaissance revealed he had been spotted, so he decided to retreat northwest at 24 knots. Thirty minutes later, when his scout aircraft located Task Force 58, Ozawa opted to initiate a night attack with seven B5Ns and three radar-equipped B6Ns. Meanwhile, Mitscher launched a full deckload from 11 carriers, including 85 Hellcats, 77 dive-bombers, and 54 Avengers. The First Mobile Fleet was not well positioned to meet the attack. The Van Force with most of the heavy escorts and the best antiaircraft capabilities was not the closest formation to the incoming American strike. Each of Ozawa’s three groups was headed northwesterly with the Van Force to the south, Carrier Division 2 in the center and Zuikaku to the north. Astern of the carrier groups were the two supply groups composed of six oilers with their escorts, making this the closest group to the Americans. After an uneventful flight, the American aircraft found the 1st Mobile Fleet at 18:40, at the edge of their fuel range after nearly 300 miles. Lacking time for a coordinated attack, the American aircraft easily bypassed the 40 fighters and 28 bombers sent to intercept them and individually targeted the enemy carriers. The veteran carrier Zuikaku was defended by 17 fighters and put up a good fight with heavy antiaircraft fire and adept maneuvering. She avoided the four torpedoes aimed at her from the Hornet Avengers and took only a single direct hit by a 500- pound bomb aft of the island. After departing, the Americans reported the big carrier with heavy fires onboard. However, the damage was not as great as it appeared. The single bomb hit penetrated to the upper hanger deck where a fire started among the remaining aircraft. These were not fueled, so after a few tense moments and an order to abandon ship that was quickly rescinded, the fire was extinguished. Six near misses were recorded, but overall damage was light. Zuikaku, the last surviving carrier from the Pearl Harbor attack force, lived to fight again.
Aircraft from Bunker Hill, Monterey, and Cabot attacked the Chiyoda group, which evaded five torpedoes and sustained one bomb hit, surviving to fight another day. The Japanese were organized into three groups, each centered on a light carrier with several escorting battleships or heavy cruisers. The Zuiho and Chitose groups were not attacked, but the Chiyoda group was. The light carrier was the target of over 20 Helldivers and Avengers with bombs, but only a single bomb hit Chiyoda on the flight deck resulting in 20 dead, 30 wounded and two aircraft destroyed. The Avengers from Monterey probably scored the single hit, which caused a fire that was quickly extinguished. Chiyoda successfully dodged five torpedoes from Bunker Hill Avengers and lived to fight another day. Escorting battleship Haruna was hit by a 500-pound bomb that penetrated her stern and flooded the steering compartment. The ship’s speed was reduced, and 15 crewmen were killed and 19 wounded. Cruiser Maya endured a near miss that caused flooding.
The strike group from Lexington, with support from the Avengers from Enterprise, Yorktown, and Belleau Wood, and the bomb-carrying Hellcats from Hornet and Yorktown, attacked Admiral Jojima’s carriers. They inflicted minor damage on Junyo and Ryuho. Most of Lexington’s Dauntless dive-bombers selected Junyo for attention. At 7:04, one or two bombs hit the carrier’s island, and several near misses created minor flooding. Casualties included 53 dead, but overall damage was light. Light carrier Ryuho was attacked by the five Avengers from Enterprise with bombs at 7;10; eight hits were claimed, but only slight damage was caused by near misses. The carrier also survived attacks from Enterprise Dauntlesses, Avengers from Yorktown five with torpedoes and probably Hellcats from Hornet.
Hiyo suffered the most successful attack of the evening. The carrier left the formation to launch two Jills to lay a smoke screen and was caught behind the main body when the American strike arrived. In the opening attack by Dauntlesses from Lexington, one bomb hit the foremast and exploded above the bridge resulting in heavy casualties to bridge personnel. The Japanese reported that another bomb hit the flight deck. However, the group of four Belleau Wood Avengers with torpedoes caused fatal damage. Three conducted an anvil attack, and one torpedo hit the carrier’s starboard engine room. This was followed by a dive-bomb attack from six Enterprise Dauntlesses. The single torpedo hit, the only one scored by Avengers during the entire attack, proved fatal to the largely unprotected carrier. Within minutes, the damage created a list. The ship proceeded for a time on its port engine, but then went dead in the water. Just before sunset, at 1917, there was a large explosion amidships that caused a loss of power. The Japanese were convinced that this was the result of a submarine-launched torpedo, but there were no submarines in the area. A fuel-fed conflagration ensued, causing multiple explosions. The fire was beyond being contained, and the order to abandon ship was given.
Hiyo sank at 20:32, claiming 247 crew members. The final American counterattack came from Wasp’s aircraft, targeting Ozawa’s Supply Group to disrupt the withdrawal of the 1st Mobile Fleet by damaging the oilers. Three oilers were damaged, and two were later scuttled. In this series of uncoordinated attacks, the Americans lost 20 aircraft and destroyed 80 Japanese planes; although the results were underwhelming, with only one carrier sunk, they fared better than Ozawa’s combined strikes the previous day. At 20:45, American aircraft began returning to their carriers. The distance from the targets to TF 58 was between 240 and 300 miles, so fuel exhaustion was a real danger for many pilots. On a dark night, the returning aircraft began to return to their carriers at 8:45. Mitscher decided to ignore the potential Japanese air and submarine threats and ordered his ships to use extra illumination beyond the normal landing lights on each carrier deck to guide his appreciative aviators home. Any pretense of order was quickly lost and soon aircraft were ordered to land on any deck in sight. Almost half of the returning aircraft landed on the wrong carrier. This hectic scene took over two hours to play out. When the final accounting was complete, aircraft losses were expectedly heavy. The Americans would end up losing a total of 100 pilots and 109 crew members. Meanwhile, Admiral Toyoda ordered Ozawa to disengage from the decisive battle and retreat northwest, with the Japanese fleet successfully evading Mitscher’s slow pursuit and reaching Okinawa on the afternoon of June 22.
Once more, the Japanese sought a decisive battle but were decisively defeated. By the end, they had lost three carriers sunk, two carriers damaged, 395 carrier aircraft, about 200 land-based aircraft, two oilers, and four other damaged ships, with around 3,000 Japanese fatalities. In contrast, the Americans lost 130 aircraft and 76 aviators, with none of their damaged ships rendered out of service. The Battle of the Philippine Sea, the last carrier-versus-carrier battle of the war, stood out because the most conservative and defensive-minded side emerged victorious. In terms of scale the Great Marianas Turkey Shoot dwarfed the four carrier battles that preceded it. At the Battle of the Coral Sea, the Battle of Midway, the Battle of the Eastern Solomons, and the Battle of Santa Cruz Islands, the largest carrier engagement involved 7 carriers at Midway; by comparison there were 24 carriers at the Great Marianas Turkey Shoot. It was, by a factor of almost 350 percent, the biggest carrier battle in history. Though Mitscher’s Combat Air Patrol was not flawless, the combination of inadequate Japanese aircrew training and American radar-directed fighter interception rendered a significant Japanese strike ineffective. Ozawa conducted an intelligent battle, accurately assessing American intentions to launch carrier air strikes that would have been catastrophic to a carrier task force by 1942 standards. Nevertheless, his tools failed him. Despite Ozawa's skilled fleet handling, he lacked the airpower to inflict serious damage on Task Force 58. Admiral Spruance has faced criticism for his cautious approach, which exposed his carriers to attack without a strong chance of striking back at the enemy. Only the significant difference in skill between American and Japanese aviators and some good luck prevented this strategy from failing.
Now back over on Saipin, General Watson continued to focus mainly on patrolling, while the 8th Marines worked to secure Hill 500. Colonel Wallace’s 2nd Battalion encountered minimal resistance, enabling them to quickly advance to the O-4 Line. Around 09:00, the 25th Marines moved towards Hill 500, subjecting the Japanese to a severe, thundering beating administered by the 4.5-inch rockets. As the Marines charged up the hill through the thinning smoke, artillery shells walked ahead in sturdy escort. Shortly before noon the hill was seized, and mopping up of the cave network began. Compartments at different levels and angles made it possible for the Japanese occupants to retreat from one cave-room to another, and the cleaning out process was a slow one. The price for Hill 500 was not light. Chambers’ battalion suffered 49 casualties, nine of whom were killed. Counted Japanese dead numbered 44. Upon examination, it was found that Hill 500 had been well organized for defense but that the positions were not strongly manned. As darkness approached, the Marines dug in to defend their newly won possession.
Meanwhile, the 24th Marines also reached the O-4 Line near Tsutsuran, but the 27th Division struggled to push the Japanese forces onto the challenging terrain at Nafutan Point. Additionally, the 106th Regiment arrived on June 20, and Aslito Airfield became operational, putting the security of the Japanese home islands in jeopardy. The following day involved reorganizing, resupplying, mopping-up, and patrolling to prepare for the next day's attack into central Saipan. General Smith's infantry continued their offensive south toward Nafutan Point, making incremental progress through each cave and ravine.
At 12:15, while engaged in the Nafutan Point attack, the 27th Division received a change of mission and disposition. NTLF Operation Order 9 dictated less one battalion and one light tank platoon, to assemble northwest of Aslito Airfield in NTLF reserve. Control of the division artillery would pass to the 23rd Corps Artillery. The designated infantry battalion was ordered to “operate in the Garrison Area and mop up remaining enemy detachments, maintain anti-sniper patrols within the Garrison Area and along the coast line to protect installations within its zone of action with particular attention to Aslito Airfield.”
At 5:00, after consideration of the NTLForder, Ralph Smith telephoned Holland Smith and urged that a complete regiment be used to clean up Nafutan Point, rather than one battalion. He said that he planned to use the 105th Infantry for the job and that he believed they could finish in a couple of days. Holland Smith agreed to this but specified that one battalion of the 105th must be retained in reserve for possible use elsewhere. For this task, the 2nd Battalion would be selected. This modification was later confirmed in a mailbrief from NTLF which arrived at the 27th Division command post at 8;30, 22 June. Ralph Smith then issued an order to his division, the 105th will hold the present front line facing Nafutan Point, with two battalions on the line and one battalion in regimental reserve. It would relieve elements of 165th now on the front line by . Reorganization of the present front line to be effected not later than 11:00, 22 June and offensive operations against the enemy continued. Reserve battalion will maintain anti-sniper patrols in the vicinity of Aslito Airfield.

The Battle of the Philippines was the last hurrah of the once proud IJN carrier fleet that had humbled the American two and a half years earlier. Admiral Spruance's strategic patience led to a decisive American victory. Japan's carrier threat, which had driven its early wartime expansion, was annihilated in the Great Marianas Turkey Shoot.

- 134 - Pacific War - Invasion of Saipan, June 11-18, 1944
11 jun· The Pacific War - week by week
Last time we spoke about the fall of Mogaung. General Vinegar Joe’s strategy against Myitkyina had turned into a brutal struggle. Stillwells forces were besieging the town while the Chindits battled for Mogaung, diverting Japanese reinforcements in the process. Despite heavy losses, the Chindits captured Naungkyaiktaw with the help of flamethrowers. Gradually Mogaung fell, but the credit was wrongly attributed to the Chinese while it should have gone to the Chindits. Mytikyina withstood endless attacks and at Biak the Americans repelled numerous Japanese assaults. The 2nd battalion, 162nd regiment tossed over to help, but this further complicated supply issues on the plateau. Progress was deeply hampered by water shortages, difficult jungle terrain and supply roads needing repairs. Lastly the battle for Lone Tree Hill saw absolute mayhem and horror, something the Americans and Japanese would never forget.
This episode is the Invasion of Saipan

The use of US fleet and escort carriers during the landings on Hollandia and Aitape had convinced Admiral Toyoda’s staff that the American naval force could be drawn into decisive naval battle off of New Guinea. On June 1st, however, a reconnaissance flight had discovered a major build up of enemy vessels at Majuro, suggesting that a new invasion was just days away. The Imperial General Staff reeled with shock in response to this, not knowing whether the Allied objective was Biak, Palau or Saipan. Aboard Toyoda's flagship Oyodo in Tokyo Bay, the naval staff debated, and the debate degenerated into argument. The truth was that no one had a “feel” for the American strategy except one lone staff intelligence officer, Commander Nakajima Chikataka. He said it had to be Saipan. But his fellow staff members scoffed at this. Even the Americans did not have such power that they could mount an operation the size of the three-pronged New Guinea strike as just a feint, they argued. They further argued that an enemy airfield at Biak would allow the Allies to bomb the Philippines and Palau with their long-range B-24 Liberators. And the American carriers were in evidence off New Guinea, unlike at Majuro. Thinking that Nakajima must be seeing things, Toyoda thus decided that Biak had to be the place. The Japanese unleashed Operation KON, diverting an enormous sum of their naval and air resources to bolster Biak in response to the perceived allied advance.
However, in actuality, Admiral Spruance was gathering the largest Pacific force yet seen at Pearl Harbor, comprising approximately 535 ships, ranging from battleships to tugs, carrying a total of 127,500 personnel of Lt-General Holland Smith’s 5th Amphibious Corps.
They were going to hit Saipan, Tinian and Guam. Designated “Operation Forager” it was to be the end game of Admiral Nimitz Central thurst into the Pacific. Taking these would see strategic airfields only 1400 miles away from Tokyo in the hands of the allies. From there the US Army Air Force could begin their long wished bombing campaign against the Japanese home islands. For the Japanese, Saipan in particular was considered a “home island”. Japan had seized Saipan during WW1 from the German Colonial Empire and she heavily invested in “Japanizing” the island. The Japanese government had encouraged southern Japanese and Okinawans to colonize Saipan, introducing Japanese language and culture to the indigenous peoples there. It was more than just another Imperial asset, in many ways Saipan had become a home island.
Part of the new operation would include Admiral Mitscher commanding the Fast Carrier Task Force 58 stationed at the Marshalls, along with Vice-Admiral Charles Lockwood overseeing 19 submarines and Rear-Admiral Ralph Christie leading 9 submarines operating across the Pacific and Southeast Asia. Operation Forager entailed Admiral Turner's Task Force capturing Saipan and Tinian sequentially with the 2nd and 4th Marine Divisions, followed by the 3rd Marine Division and the 1st Provisional Marine Brigade attacking Guam. The 27th Division was reserved for Saipan and the 77th Division for Guam. The outcome on Saipan would determine subsequent operations, with the Southern Landing Forces also held in reserve for the Northern Landing Forces until June 25. Lieutenant-General Holland Smith's strategy for the Saipan invasion involved landing four assault regiments simultaneously on four beaches in the Charan Kanoa area. Following three days of continuous air and naval bombardments, Major-General Thomas Watson's 2nd Marine Division's 6th and 8th Marine Regiments were to land north of Afetna Point on the Red and Green Beaches, while Major-General Harry Schmidt's 4th Marine Division's 23rd and 25th Marine Regiments would land south of Afetna Point on the Blue and Yellow Beaches.
Thomas Watson was then going to seize the Charan Kanoa Airstrip, afterwards he would sing northeast towards Mounts Tipo Pale and Tapotchau while Schmidt secured Charan Kanoa village, the Aslito Airfield and the islands southern end before moving north to take part in clearing the remainder of Saipan. Alongside this, Smith planned to dispatch the reserve 2nd and 24th Marine Regiments of Lt Colonel Walter Stuart and Lt Colonel Guy Tannyhill over to Scarlet and Black Beaches in the north to divert enemy attention. Two innovations would be tried for Forager. The 4th Marine Division had recently and optimistically accepted the proposal to employ amphibian tanks inland. This was a large part due to the unit's experiences on low and level Roi-Namur, during the Kwajalein assault. The 2nd Marine Division on the other hand, having fought on rugged Guadalcanal and experienced the limitations of LVTs during the Tarawa assault, were more pessimistic. General Watson convinced General Smith that he would only allow the amphibian tanks to advance inland far enough to clear the immediate beach area and that only the first troop-carrying LVT wave would follow them to discharge their troops beyond the beach. All subsequent waves would discharge troops on the beach and not proceed beyond the Tractor Control Line. The reason for this pessimism was that the Marines expected the terrain to be rougher than some predicted. They feared control would be lost over troops embarked in LVTs, concentrated groups of men would be exposed to fire, and that more amtracs would be lost to enemy fire inland. They were needed to return to the Transfer Control Line on the reef's lip where support troops boated aboard LCVPs would be picked up and run to shore in the amtracs. Furthermore, LVTs are not designed for cross-country movement. They have comparatively narrow tracks and low ground clearance, making it easy for them to "belly-out" on rough ground, rocks, and stumps. Amphibian tanks are poor substitutes for medium tanks for the same reasons, and in addition they have very thin armor and a high profile.
The Marine divisions commenced training for Saipan in March, conducting a significant rehearsal between May 14 and 20 off Maui. With all arrangements in place, Admiral Turner’s invasion fleet was poised to depart Hawaii by late May. The slower LSTs were scheduled to set sail for Eniwetok on May 25, followed by the troop transports departing Hawaii five days later. Turner’s vessels were slated to gather at Eniwetok on June 6, coinciding with the departure of Admiral Mitscher’s carriers from Majuro for the Marianas. Between June 8 and 10, Turner then embarked from Eniwetok in echelons, experiencing a relatively uneventful voyage towards Saipan. Meanwhile, the Japanese expedited the deployment of 31st Army units to the Central Pacific, successfully positioning most of their line units at designated locations by the end of May. Additionally, certain disparate units of the 31st Army underwent reorganization into seven independent mixed brigades and five independent mixed regiments to enhance chain of command and troop cohesion.
This, however, did not allow adequate time to prepare inland defenses in multiple lines, especially in the case of the Marianas. The larger elevated islands within the Marianas offered strategic advantages for establishing multi-layered defenses, creating strongholds on key terrain features, and positioning reserves centrally for potential counterattacks. However, the Japanese were unable to fully exploit these opportunities due to various factors. Insufficient troop deployments occurred until less than two months prior to the US assault, leaving limited time for comprehensive inland defense preparations. Many coastal defense and anti-aircraft guns were discovered still packed and alongside incomplete positions, due to a shortage of construction materials for fortified installations. Consequently, the high ground at the island's center remained unprepared for defense, and several beach defenses were unfinished. There was an overestimation of the natural ruggedness of the terrain to impede American advances. Despite this, some coastal defense guns were strategically placed within earlier reinforced concrete structures. While Saipan and Tinian lacked significant artificial underwater or beach obstacles, mines were sporadically utilized on their shores.
The Japanese also suffered from a lack of anti-aircraft ammunition to counter the enemy air superiority. Over on Saipan, Lieutenant-General Saito Yoshitsugu commanded a significant military presence including the 43rd Division, the 47th Independent Mixed Brigade, the 9th Tank Regiment, the 1st Battalion of the 18th Regiment, and various support units totaling 25,500 personnel. Despite its apparent strength, a convoy carrying reinforcements for the 43rd Division was ambushed by two American submarines between June 4 and 6, resulting in the loss of five transports and nearly decimating the 118th Regiment. Saito, overseeing Saipan as commander of the Northern Marianas Army Group, was joined by Admiral Nagumo's Central Pacific Area Fleet headquarters, bolstering defense with an additional 6,200 naval personnel. Additionally, General Obata, stationed at Saipan's army headquarters, delegated authority to his chief of staff, Major-General Igeta Keiji, as he inspected defenses in Palau during the American landings. Saito organized Saipan's defense into five sectors, anticipating landings on the island's west and northwest coasts, Tanapag Harbor, and the north shore of Magicienne Bay. The Japanese strategy relied on tank-infantry counterattacks launched at night from designated positions to repel enemy landings. However, American bombardment of Saipan commenced before Saito's forces could fully fortify their positions. Large numbers of heavy weapons, ranging from 200mm mortars to 5-inch coastal defense guns and literally dozens of searchlights and antiaircraft guns still remained in naval depots or loaded on railroad cars or still packed in cosmoline near partially excavated gun positions. The high ground in the island's center had received little attention in the defensive preparations; and, indeed, beach defenses themselves were in many cases far from complete. In so far as training in defensive warfare is concerned, Japanese forces displayed a marked deficiency; there was little evidence of organization of the ground, the principal airfield (Aslito) was virtually undefended against ground troops, and their counterattack plans were poorly conceived.
On the afternoon of June 11, Mitscher’s Task Force 58, began a relentless three and a half day heavy bombardment against Saipan, Tinian, Guam, Rota, and Pagan. This onslaught, featuring a 225-plane fighter sweep, caught the Japanese off guard in the Marianas and resulted in the destruction of 150 enemy aircraft, securing air superiority for the rest of the campaign. On June 12th and 13th, 216 carrier bombers hit Guam, Saipan, and Tinian, while Admiral Hoover's B-24s started pounding the southern Marianas airfields. You might be raising your eyebrows, the B-24’s belonged to Task Force 57, under Vice-Admiral John Hoover, which was currently formed by the 5th Air Force over on Cape Gloucester and New Guinea; the 7th Air Force and 4th Marine Aircraft Wing on the Marshall and Gilbert Islands; and the 13th Air Force on the Admiralty Islands. Concurrently, two Japanese convoys were intercepted, leading to the sinking of 16 enemy vessels. The first of these, was a formation of 20 ships, fleeing on a northerly course 125 miles west of Pagan Island. They were attacked on the afternoon of the 12th by planes of Rear Admiral William K. Harrill’s Task Group 58.4. Further south, 135 miles west of Guam, the other convoy of six ships became the target for a special attack mission sent by Rear Admiral Joseph J. Clark, commanding Task Group 58.1. Between the two attacks 12 cargo ships, three submarine chasers, and one patrol-torpedo boat were sunk. Additionally, on June 13th, Mitscher's fast battleships shelled Saipan, though with limited success. The following day, Turner's fire support ships joined Task Force 58 in bombarding Saipan's beaches and installations, effectively neutralizing most of the Japanese coastal defenses and anti-aircraft positions. Despite some damage inflicted on the destroyer Braine and battleship California, Saito's defenses were not completely destroyed, indicating that the preliminary bombardment was not entirely effective. Meanwhile, underwater demolition teams surveyed the landing beaches, clearing them of mines and obstacles and creating gaps in the reefs for the amphibious approach. Smith's reserves staged a demonstration off Tanapag to divert Japanese attention, while carrier groups were dispatched to prevent enemy aircraft staging through the Bonins, successfully attacking Iwo Jima, Chichi-jima, and Haha-jima.
To deter the Japanese from utilizing the Bonins in the north as a staging area for aircraft, two task groups led by Clark's 58.1 and Harrill's 58.4 set sail from Saipan on June 14th for an offensive. This marked the furthest advance into Empire waters by a carrier striking force at that time. Task Groups 58.1 and 58.4 refueled on June 14th and were then dispatched that night toward Chichi and Iwo Jima. Airstrikes on Japanese airfields in those locations commenced the following afternoon despite challenging weather conditions. Despite facing strong resistance from the Japanese, American fighter sweeps and bombing runs resulted in the destruction of 28 out of 37 Zeros engaged, with an additional seven destroyed on the ground, while only two American aircraft were lost. Adverse weather hampered morning strikes on the 16th, but the afternoon sortie of 54 American aircraft encountered Japanese planes on the runway, claiming 63 destroyed, though this wasn't confirmed by Japanese sources. Only two American aircraft were lost due to anti-aircraft fire and operational issues. Despite airborne opposition and unfavorable flying conditions, the mission achieved its objectives, significantly diminishing the Bonins' effectiveness as an aircraft staging area. After the afternoon raid, the two task groups headed south as per Mitscher's orders to position themselves off Saipan by the 18th. This operation proved successful, as around 100 Japanese aircraft that could have intervened in the impending battle were eliminated.
On the morning of June 15, while the landing craft were lowered and began the complex assembly process, the Americans carried the last air and naval preparations on Saipan. At 8:12am, Turner finally gave the landing signal and the amtracs began to approach their assigned beaches under the cover of the LCI gunboats’ rockets. Enemy fire was light until the LVTs reached the coral reef's lip, at which time artillery, mortar, and machine-gun fire increased drastically. Some control craft had drifted slightly to the north and coupled with a stronger than expected current some 2nd Marine Division units landed north of their intended beaches. The UDTs had not experienced this as the sea conditions and tides were different when they went to work the day before. Once over the reef lip some 400yds from shore, the swell made stationkeeping even more problematic. The swell increased through the day, making unloading and transfer difficult as well as capsizing landing craft and LVTs. The 2nd Marine Division had 31 of its 68 amphibian tanks hit or mechanically disabled before reaching the Tractor Control Line ashore. Nonetheless, in 20 minutes, some 8000 assault troops were ashore despite the strong Japanese artillery fire, albeit suffering heavy casualties. On the Red Beaches, Colonel James Riseley’s 2nd and 3rd Battalions encountered stiff resistance from Hill 500 but still managed to secure a shallow beachhead, subsequently repelling a savage counterattack as the reserve 1st Battalion was landing. To the south, as Colonel Clarence Wallace’s 2nd and 3rd Battalions had both come ashore on Green Beach 1, the 2nd would be sent south to seize Afetna Point while the 3rd advanced inland. Afetna Point was important for another reason than just denying the Japanese excellent positions for enfilading the American landing craft. Possession of the point would make Beach Green 3 available for landing of the tanks of both divisions. Because of an open channel off Green 3, LCM’s carrying tanks could proceed directly to the beach without crossing the troublesome reef that fenced all other beaches. Once through the channel the craft could either move straight into Green 3 or fan out to the north or south and put the tanks ashore, wherever it was desired. The same channel could also be used for logistical purposes after tanks were ashore. As a result, the 2nd met strong resistance, progressing slowly and costly against a determined foe while the 1st Battalion was being landed; yet the 3rd managed to push inland against weaker resistance, finally halting about 900 yards from the O-1 Line. In the afternoon, the reserve 1st Battalion, 29th Marines was also landed and employed to fill the gap between Wallace’s battalions. It’s also important to note that the 4th Company, 9th Tank Regiment conducted piecemeal counterattacks on either side of Charan Kanoa with 14 tanks, losing all but three.
Meanwhile, along the Blue Beaches, the 23rd Marines led by Colonel Louis Jones made headway through Charan Kanoa, facing occasional gunfire, and successfully advanced to the O-1 Line. Despite encountering challenging terrain and harassment from Japanese riflemen, their amtracs managed to secure Mount Fina Susu, albeit with significant losses. Upon reaching the O-1 Line, heavy artillery fire pinned down the Americans. Because of the concentrated mortar and artillery fire which had struck his troops throughout the day, the commander of the 23rd Marines, Colonel Jones estimated that the light forces on the O-1 line would be incapable of holding there for the night without being virtually annihilated. In addition, the regimental commander felt that “pulling back would allow our artillery and air to bring fire on the Jap batteries a short distance inland, better contact could be obtained on the right, and the exposed left flank could be better protected.” Dillon’s 2nd Battalion and Cosgrove’s 3rd Battalion were therefore ordered to establish a defense line generally 800 yards west of O-1 for the night. This involved a withdrawal under cover of darkness of the meager forces on O-1.Concerned about the exposed left flank between the 2nd and 4th Divisions, Colonel Jones directed the reserve 1st Battalion to fill the dangerous gap.
Further south, Colonel Merton Batchelder’s 1st Battalion faced fierce resistance from Agingan Point, repelling enemy counterattacks with the aid of air and naval support. Reinforcement from 3rd Battalion units allowed partial clearance of Japanese positions. The 2nd Battalion to the left encountered enemy concentrations but benefited from the heroic actions of the LVTAs, enabling them to advance inland.
About half the assault Marines of this battalion were carried to a railroad embankment prior to debarkation from LVTs. Until it reached there, the battalion was subjected to frontal small-arms fire from Japanese behind the embankment. There the small arms fire ceased, but mortar and artillery fire continued. From the direction of Nafutan Point came shells which burst overhead, apparently from antiaircraft guns depressed to fire at ground targets. And, as if troubles to the front and flanks were not enough, two enemy mortars began firing on the Marines from positions 500 yards to the rear. Before a request for assistance could be made, friendly planes spotted the mortars, attacked, and silenced them. Much credit for the 2nd Battalion’s success in pushing inland goes to the LVT(A)s of the Army’s 708th Amphibian Tank Battalion, which, according to the Marine battalion commander, Lieutenant Colonel Hudson, took “more than their share of punishment diverted enemy attention from the amphibious tractors carrying troops ... I shall always re- member the excellent support given to my battalion by the Army LVT(A)’s”. Meanwhile, Marine tanks and artillery, under Turner’s command, were successfully brought ashore, although some tanks and howitzers from the 4th Division were lost to fire and reef obstacles. By late afternoon, the bulk of the reserve 2nd and 24th Marines were landed, with the latter sustaining 400 casualties from accidents and artillery fire. Lieutenant Colonel Alexander A. Vandergrift, therefore, deployed his battalion and moved it on foot to an assembly area some 700 yards inland from Yellow 1, near a fork in the rail- road tracks. The men had no more than taken entrenching tools in hand when a barrage of well-directed Japanese artillery fire engulfed them. After the day’s casualties were totalled, it was discovered that the unit had suffered heavily, though it had yet to enter the front line fighting: 25 killed, 72 wounded, 39 missing, mostly those lost on board the overturned LVTs. Other battalions had suffered more heavily, but the real significance of these figures lies in the fact that the 3rd Battalion did not arrive on the beach until 5:27pm. However, by nightfall, only the 25th Marines had reached the O-1 Line, constituting less than one-third of the planned beachhead, with casualties exceeding 2000 during the landings.
After half an hour of the Saipan Invasion, Admiral Toyoda announced Operation A-Go proclaiming "The fate of the Empire rests upon this single battle. Every man is expected to do his utmost." The same Nelsonia words used by Admiral Togo at the legendary battle of Tsushima in 1905. He had created that statement taking Nelson’s signal "England expects that every man will do his duty" at the Battle of Trafalgar. Toyoda planned to destroy the American fleet. Admiral Ugaki’s battleships were to rendezvous with Admiral Ozawa’s carriers in the Philippine Sea to attack the American fleet around Saipan. At 6:35pm on June 15th, the submarine Flying Fish reported that a force of Japanese battleships and at least three carriers had passed through the San Bernardino Strait. The submarines were under orders to report sightings before attempting to attack, so Flying Fish waited until nightfall, then surfaced to radio in its report. The sighting report from the submarine was monitored by the Japanese who knew they had been located. About one hour later, submarine Seahorse also sighted a Japanese force 200nm east-southeast of Surigao Strait. The exact composition of this force was unclear, but was thought to be Yamato and Musashi plus escorts. The submarine was not able to send a signal of its sighting until 4:00am on June 16th. Additionally, throughout the 15th, a growing body of signals intelligence indicated that a major IJN fleet action was underway.
Receiving this intelligence on the enemy's intentions, Admiral Spruance made the decision to halt the Guam landings, instructed for unloading at Saipan to continue until June 17th only, and tasked Turner with preparing for an imminent decisive battle. However, that's a podcast for next week. General Saito was on the verge of initiating his counterattack. Throughout the night, there were various probes and minor counterattacks that were swiftly repelled. Nonetheless, the 2nd Battalion, 6th Marines faced a major assault at 3am when a Japanese bugler 75 sounded a loud, clear call on the tense night air, and with a waving of flags, loud screams, and a brandishing of swords, the attack was launched. Added to the din were the shouts of the 6th Marines for “flares.” Illumination shells, fired by the three destroyers, Halsey Powell, Coghlan and Monssen of Task Unit 52.17.3 began to burst over the area, clearly revealing the Japanese attackers. Men of Companies F and I opened with accurate, devastating lire. California joined with a tornado of salvos in front of the Marine lines. The Japanese, stripped by the illumination of the advantage afforded by their superior knowledge of the terrain (so helpful in night lighting), dropped before the Marines’ fusillade. As Japanese fell, others replaced them in the determined onslaught.
At one point in the fighting, it was feared that the enemy had effected a penetration of Company I, along the coastal road. To contain this Japanese prong, Colonel Riseley shifted one company of the 3rd Battalion, 2nd Marines, company L, into the area. The light of morning, however, revealed that no penetration had been made and that Company B had, in effect, formed a secondary line. By 5:45, the Japanese pressure reached a peak; two Marine 37mm guns near the beach were knocked out and their crews forced back. Although the main positions held, a false report reached the 6th Marines’ command post to the effect that Company F’s lines along the beach had been forced back about 50 yards. This erroneous report, probably fostered by the withdrawal of the two 37mm crews and the infiltration of small enemy groups to the regimental command post, had no basis in fact.
Fortunately, five medium tanks arrived in the nick of time to halt the Japanese advance and thwart their assault. With the dawn of June 16th, the battlefield revealed approximately 700 enemy casualties strewn across the terrain. Meanwhile, as the 6th Marines consolidated their position and the remaining 2nd Marines landed, Colonel Wallace’s 2nd Battalion resumed its offensive against Afetna Point, successfully eliminating enemy resistance and bridging the gap between Marine divisions. Further south, General Schmidt led his three regiments towards Fina Susu Ridge in a coordinated advance. Despite the 23rd Marines encountering formidable enemy opposition in the mountains and marshes, the 25th Marines managed to clear Agingan Point and extend beyond the beachhead, while Colonel Franklin Hart’s 24th Marines in the center made significant progress towards the O-1 line despite facing fierce resistance.
Meanwhile, Spruance opted to withdraw the unnecessary transports in anticipation of the impending naval confrontation. General Smith made the decision to deploy the reserve 27th Division for landing. Consequently, Major-General Ralph Smith's units, excluding the 106th Regiment, commenced landing operations in the afternoon. However, during the night, Saito initiated his second significant counterattack. The Japanese 136th Infantry (two battalions) and 9th Tank Regiments were to counterattack the center of the 2nd Marine Division sector at 17.00hrs. Yokosuka 1st SNLF was to attack the north flank from the Garapan area and “cooperate with the tanks to annihilate the enemy’s front line and advance towards Oreai (Charan Kanoa) Airfield.” Vice Admiral Nagumo, Commander Central Pacific Fleet and 5th Base Force, was ordered to command the attack personally. The units were still disorganized from the previous night's action and the attack was not launched until 03.30hrs. The objective of the Japanese attack was modest enough: the Saipan radio station, a short 400 yards behind the 6th Marines’ lines. This objective, in itself, represented a revision in Saito’s pre-D-Day policy to “destroy the enemy, during the night, at the water’s edge." Seizure of the radio station area would still leave 500—600 yards distance to the water. This resulted in an estimated 44 tanks and 500 infantry attacking the positions of the 1st Battalion, 6th Marines, and 2nd Battalion, 2nd Marines. The attack began at about 3:30, and the brunt struck Lieutenant Colonel Jones’ 1st Battalion, 6th Marines, and to a lesser extent the 2nd Battalion, 2nd Marines. The tanks advanced in groups of four or five with Japanese soldiers clinging to them. Poor and ineffective tactics reflected the inadequacy of Saito’s order; some tanks cruised about in an aimless fashion, some bogged down in the swampy ground, some made an effort to break through the lines, still others stopped to let off their pugnacious passengers. The Japanese suffered heavy losses, including approximately 24 tanks and 300 men, while inflicting only 97 casualties. By the end of the initial two days, American forces had incurred roughly 3,500 casualties, approximately 20% of the total for the operation. Concurrently, General Obata had instructed the commanders of Guam, Truk, and Tinian to send reinforcements to Saipan via barge, although only two companies managed to land on Rota by June 22nd. On June 17th, the American offensive resumed, yielding significant progress, partly due to artillery support. General Watson expanded the beachhead area nearly twofold, with the 3rd Battalion, 2nd Marines, and 2nd Battalion, 6th Marines advancing northward to within 1000 yards of Garapan. Meanwhile, Colonel Riseley's remaining units secured the base of Mount Tipo Pale along the O-2 Line, and Colonel Wallace's Marines maneuvered around Lake Susupe to reach the O-1 Line.
To the south, the 25th Marines led by Colonel Batchelder advanced in a column formation, making headway towards Aslito Airfield by approximately 1500 yards. They managed to secure advantageous high ground along the O-2 Line on the northwest perimeter of the airfield. Simultaneously, Colonel Gerard Kelley’s 165th Regiment also moved towards Aslito, making gains of around 1200 yards despite encountering light resistance. By 2:00pm, the 2nd Battalion had moved to the southwest edge of Aslito Airfield, while the 1st Battalion had become involved in a fight for a dominating ridge line extending from the airfield's southwest corner to the vicinity of Cape Obiam. Infantrymen of the 1st Battalion led by Major James H. Mahoney inched slowly up the steep and open slope, so that, by 5:00pm, a toehold had been gained at the crest. At this point, however, the Japanese launched a counterattack and drove the soldiers back off the hill. Reorganizing and reforming the lines at the base of the ridge, the battalion dug in for the night. Amid heavy artillery bombardment, the 24th Marines reached and secured the O-2 Line, consolidating their position on the ridge. In contrast, progress for the 23rd Marines to the south of Lake Susupe’s swamps was minimal as they faced entrenched enemy forces. With the expansion of the beachhead, additional Corps units landed, including General Smith’s command post, advance parties of the Corps artillery, and Colonel Leonard Bishop’s 105th Regiment. During the night, Saito launched another counterattack, deploying the 1st Battalion of the 18th Regiment to stage a counterlanding on the Marine beachhead. However, the intervention of LCI gunboats and Marine artillery thwarted the attempt, driving the enemy back to Tanapag Harbor. Shifting focus to the Battle of Biak, General Fuller’s forces had previously seized Mokmer but now found themselves encircled by Colonel Kuzume’s formidable positions in the East and West Caves. Despite progress in repairing the airdrome, intense Japanese fire prevented its use until the enemy cave strongholds were neutralized.
In contrast, the Japanese had attempted twice to reinforce Biak but failed both times. However, Operation KON drew the Allied forces away from the island, allowing barges to discreetly bring reinforcements from the southwest to Biak without naval protection. As a result, most of the 2nd Battalion, 221st Regiment was successfully transported to the island by June 12, and General Numata was evacuated during this period. Following this success, the 2nd Battalion, 219th Regiment was loaded onto barges in Sorong and transported to Biak via Noemfoor Island, arriving successfully by June 16. Meanwhile, as Colonel Newman’s 186th Regiment secured its positions on June 8, Fuller decided to send the rest of Colonel Haney’s 162nd Regiment to the recently secured Parai Jetty. With the Ibdi Pocket contained, Haney made significant progress toward Mokmer. The next day, Haney continued his advance, successfully connecting with his 2nd Battalion despite heavy mortar fire. Newman faced multiple night counterattacks and was unable to expand his beachhead. On June 10th the 1st Battalion, 186th Infantry, sent two companies to the point on the low ridge where Company B had been halted the previous afternoon. Despite artillery support, the two units could make little progress and were themselves pinned down about 10:30. Japanese rifle and mortar fire was silenced by the 1st Battalion's 60-mm. mortars, but the Japanese continued to pour machine gun fire from a number of bunkers and pillboxes which proved impervious to bazooka and 75-mm. tank fire. The units withdrew while more artillery fire was placed along the low ridge. On the east flank, enemy fire from the East Caves had died down, and the 2nd Battalion, 162nd Infantry, was able to move on eastward. On that same day, as Admiral Toyoda ordered a third attempt for Operation KON, Admiral Ugaki’s battleships were directed to support Admiral Sakonju’s convoy, assembling at Batjan Island on June 11th. The start of the Marianas bombardment on that day forced Toyoda to suspend the operation and prepare for A-Go, ordering the battleships to rejoin Admiral Ozawa’s command and sending the 23rd Air Flotilla to Palau to reinforce Admiral Kakuta’s 1st Air Fleet.
With two regiments now stationed at Mokmer, Fuller decided to resume his offensive by advancing westward towards Borokoe and northward towards the low ridge. The 163rd Regiment was assigned to hold the Ibdi Pocket and the East Caves. On June 11, the assault battalions began moving to the starting point in front of Menoebaboe. Haney's forces faced strong resistance and only reached the starting point by afternoon. The Americans then crossed the starting line, encountering minimal resistance along the coast but significant opposition on the low ridge. As a result, three battalions reached the 1st Phase Line, while Haney's 3rd Battalion couldn't move beyond the starting line. This forced Newman to pause his advance temporarily until Haney cleared enemy positions on the ridge. On June 12, Haney's 2nd and 3rd Battalions advanced on the low ridge. The 3rd Battalion fought doggedly forward during the afternoon, discovering an ever increasing number of Japanese pillboxes, bunkers, and hasty automatic weapons and rifle emplacements of all kinds, manned by 1st Battalion and 5th Company, 222nd Regiment. Dusk found the unit still some 100 yards short of the line of departure and about 1,300 yards east of the 2nd Battalion. The 1st Battalion, taking no part in the action during the day, moved forward to Mokmer Drome from Parai. Due to heavy Japanese resistance, their progress was slow. The next day, the Americans continued their attacks against enemy positions, but they couldn't close the gap between Haney's 2nd and 3rd Battalions. Fuller concluded that his troops were fatigued and that the Japanese had likely received reinforcements, so he requested an additional infantry regiment. General Krueger planned to send the 34th Regiment from Hollandia, scheduled to arrive on June 18. In response to recent setbacks, General Doe ordered the 1st Battalions of the 162nd and 186th Regiments to support the 3rd Battalion on June 14. These battalions positioned themselves on the terrace above the low ridge, facing the main Japanese strongpoint directly.
In response to the enemy's aggressive action, Colonel Kuzume initiated a tank-infantry counterattack with his remaining forces to push back the enemy battalions, inflicting heavy casualties and disrupting the American advance. Despite this, the Americans managed to regroup and establish a continuous line, while the Japanese sustained significant losses and were unable to execute any further major counterattacks for the rest of the battle. Generals Krueger and MacArthur were unhappy with the progress of operations in Biak, which led them to relieve Fuller of his duties as task force commander. Whether General Fuller's relief as commander of the HURRICANE Task Force was entirely justifiable is a question which cannot be answered categorically. At the time of his relief, the task force had seized Mokmer Drome. Patrols sent westward to Borokoe and Sorido Dromes had found no enemy at those two fields, and General Fuller knew they could be occupied with ease. But he had not sent more troops beyond Mokmer Drome because he believed it more important to secure an overland line of communications to that field and to clear the low ridge so that repair work could continue and at least one strip could be put in service. By June 14th it was only a question of time before the West Caves area and the low ridge would be secured. Indeed, General Eichelberger, who took 3.5 days to acquaint himself with the situation at Biak, drew up new attack plans according to which the 162nd and 186th Infantry Regiments were to be employed in the same area and in much the same manner as General Fuller had been using them. General Eichelberger realized, as had General Fuller, that Borokoe and Sorido Dromes would be no safer than Mokmer Drome as long as the Japanese held the low ridge and West Caves positions. But, in the last analysis, the mission of the HURRICANE Task Force, quick seizure and rehabilitation of the Biak fields, had not been accomplished by mid-June. General Eichelberger then took command of Operation Hurricane on June 15. Although the initial plan was to keep Fuller in charge of the 41st Division, he felt unjustly treated and requested to be relieved of this role as well. Consequently, Doe was promoted to command the 41st Division in Fuller's place.

The invasion of Saipan was seeing tremendous casualties for both the Japanese and Americans. By the end of the initial two days, American forces had incurred roughly 3,500 casualties, approximately 20% of the total for the operation. This island was not going to be a cake walk by any measure, it would be paid for in blood.

- 133 - Pacific War - Fall of Mogaung, June 4-11, 1944
4 jun· The Pacific War - week by week
Last time we spoke about landings at Biak. General Fuller unleashed a amphibious assault against Biak that faced countless hurdles. The Hurricane Task force encountered a lot of terrain issues at Humboldt bay, leading to logistical headaches. Despite the disorganization, they shipped off and landed, forming a beachhead. Colonel Kuzume and his men were caught with their pants down, units were scattered all over the place. The first tank battle of the Southwest Pacific occurred, seeing American Shermans absolutely desolate Japanese Type 95’s. General Fuller planned to consolidate his troops at Ibdi and Bosnek while reinforcements arrived, but the Japanese continuously lobbed surprise night attacks to horrible effect. Over in the Burma front, Mutaguchi’s operation continued to unravel as his subordinate officers disregarded his orders and performed their own withdrawals. As Mutaguchi relieved men of command and replaced them, General Slim finally reopened the Imphal-Kohima road spelling doom for the Japanese.
This episode is the Fall of Mogaung

As General Vinegar Joe unleashed what he believed to be a masterstroke against Myitkyina, it soon turned out to be an absolute gruesome struggle. As we last saw, General Stilwell’s men had begun a long and difficult siege of Myitkyina. The 22nd and 38th Chinese Divisions were now pinned down by General Tanaka’s battered 18th Division south of Kamaing. To the south Brigadier Calvert’s Chindits began a battle for Mogaung, which forced General Takeda’s 53rd Division to suspend the relief of Myitkyina and rush back to reinforce the town. Though the Mogaung Garrison and the 1st Battalion, 128th Regiment to the north had been effectively destroyed by the Chindit and Chinese attacks, the Japanese had been able to maintain their hold on Mogaung by mid-June. To the east, General Wei’s Y Force had opened a new offensive on Yunnan, gradually pushing Colonel Kurashige’s 148th Regiment to Tengchong but failing to seize Longling against the tenacious resistance of General Matsuyama’s forces. Along the Kamaing-Mogaung front, by late June, Tanaka had been able to assemble most of his depleted command at Lakatkawng, determined to keep the blockade on the Hukawng Valley. His main aim was to clear the Seton roadblock, which had been recently reinforced with General Sun’s 113th Regiment; but once again, his attacks would fail to dislodge the tenacious Chinese defenders. Yet upon receiving orders from the 33rd Army commander to withdraw, General Tanaka reported that the 18th Division could continue to hold in the Kamaing area. This statement, inspired by Colonel Ohgoshi, the chief of staff, proved to be unwarranted optimism. The 18th had staged a desperate resistance in the vicinity of Kamaing for about a month and, for most of the period, had only 80 men for each mile of front. Supplies of ammunition and food were very low with only about 1400 rounds of rifle ammunition per day for the entire Division and 60 rounds per machine gun. The daily ration was about 2.5 ounces of rice per man. On receipt of the Army's message to withdraw, Colonel Ohgoshi had advised the Division commander that further resistance in the area was possible, but had not made it clear that this was his personal belief and did not reflect the opinions of the rest of the Division staff. Within a day or two the commander became aware of the fact that the other staff officers were convinced that further resistance in the Kamaing area was impossible. He therefore forwarded to the 33rd Army a revised report of the Division's actual situation. Upon receipt of the second message, on June 27 the Army directed the Division to retire to the Sahmaw sector. Tanaka believed he needed to stand his ground while the 53rd Division pushed aside the Seton Block and reopened his line of communications. Thus, he elected to continue to resist the attacks from the north while he himself attacked Seton for three more days; but failing to make any progress, he would finally comply with his orders to withdraw to the hills north of Sahmaw in early July.
While the 4th and 146th Regiments performed covering attacks, the remnants of the 55th and 56th Regiments destroyed their artillery and heavy equipment, and withdrew along an escape trail cut through the forest west of the Seton roadblock. On 2 July the 18th Division began its withdrawal, utilizing an obscure trail that ran directly south from Kamaing. Crossing the mountain range west of Seton, the Division completed its concentration near Sahmaw about 7 July. The Hukawng Operation was then considered concluded, ending a campaign that had been a miserable failure and had cost almost 8,000 casualties. By July 15th, the 18th Division would finally assemble in the Indaw area. Though only 3000 men from the elite 18th Division would survive the Hukawng Valley Campaign, Tanaka had effectively managed to keep intact the blockade to China for another year, something that would have profound repercussions later on in Chinese history.
Further south, the 114th Regiment finally arrived at Gurkhaywa on June 16th, ready to reinforce the Chindits; yet Takeda had also brought most of his troops back to Mogaung, subsequently starting a deadly shelling of the Chindit positions. By when June 15th arrived, the Chinese still had not appeared, and Calvert pulled his troops back towards the bridge. At that moment, remarkable news arrived: The Japanese were abandoning their positions along the river. Calvert was exuberant. This meant he could move out of his bridgehead perhaps capture the town. Certainly, it meant a reduction of the shelling which was claiming at least 15 of his men a day. Yet, when the shelling did not die down and it quickly became apparent that Takeda was merely redeploying his troops along the railway, to get them out of flooding in low-lying areas. Chindit recce teams reported the area from the train station, in the heart of the town to the Mogaung Railway Bridge, further north, was heavily defended with eight bunkers dominating the landscape. Shelling from the village of Naungkyaiktaw, astride the road to Mogaung, set between fields of paddy, was persistent. Naungkyaiktaw had to be captured. Calvert estimated the village was held by a hundred Japanese. Because of this, on June 18th, Calvert ordered his forces to attack the apparent Japanese artillery encampment at Naungkyaiktaw after a heavy air and mortar bombardment. His troops outnumbered them, but unwilling to suffer needless casualties, Calvert directed the American fighter-bombers against the village, which was bombarded on the night of the 17th. Half an hour before dawn on the 18th, the Chindit mortars pummeled the place with 400 rounds for good measure. Calvert then sent in his assault force. Among the attackers was a company of 70 men from King’s Liverpool led by Major Fred Reeman. This was a company that had stayed on with the 77th Brigade after the rest of the battalion had been transferred to the 111th Brigade. They were joined by 12 men of Blaine’s Detachment, once evacuated to India but since returned, this time armed with about a dozen flamethrowers.
In the darkness, Blaine’s Detachment was told to advance in front of the company of King’s, and to “turn the fucking lights on.” As the detachment began to hurl flames far and wide, the Chindits behind them began cheering. The men had been told that the village had many bunkers, but never saw any at first. The scene soon turned fantastic. They went through the entire village “with twenty or thirty yards of flame shooting out in front.” They soon found the bunkers. The Japanese became crazed with fear especially after the British began yelling “put out the fucking lights,” and turning the flamethrowers their way. Many Japanese fled the bunkers, joined by those outside. They fled through the paddy fields, making for the railway station 400 yards away. Calvert’s machine gunners had been waiting and blazed away, killing at least forty. Meanwhile, the rest of Fusiliers and the Kings walked up the paddy, picking off Japanese hiding or trying to crawl away in the ditches. Calvert, his mobile brigade-major Brash and his orderly Lance-Corporal Young decided to join the mop-up, shooting at Japanese while standing on chairs, as more Fusiliers began clearing the last of the bunkers, hurling grenades into them and blasting the insides with flamethrowers. As twilight set in that day, the most peculiar thing happened. The Fusiliers were cooking an evening meal in their newly-won positions, when a weary, seven-man patrol walked into their billet and began to take off their kit. The Fusiliers who looked up casually, noticed to their horror, that the new men were Japanese. The Japanese, for their part, had not noticed. The Fusiliers lunged for their weapons and opened fire. The Japanese patrol did not survive. In all, Calvert estimated that his troops had killed about 70 Japanese in the capture and holding of Naungkyaiktaw, while suffering 16 killed and 38 wounded. Major Reeman’s King’s company had become reduced to a platoon.
Calvert was considerably cheered on the evening of the 18th, when the much promised Chinese reinforcements finally arrived, guided over the river in motorized ranger boats by a towering Chindit officer, Captain Andrew. This was the 1st Battalion of the Chinese 114th Regiment led by Major P’ang, which quickly deployed in the positions pointed out by Calvert but left the Chindits a little flummoxed when they proclaimed that they were in no particular hurry to fight as they had been fighting for years. On the following day, another battalion of Chinese arrived under the personal command of the regimental leader, Colonel Li Hung, as did a battery of 75mm pack howitzers the “6th Battery” under US Major Wayne Cook. The Chinese quickly assumed the defense of Mahaung, prompting an American liaison officer with the Chinese to send a press release that the Chinese had “captured” the village, which embarrassed Li. Cook’s battery was deployed into position at Pinhmi village began operations on the 20th, hurling fire against the Japanese positions as the Chinese infantrymen consolidated their positions. Meantime, elements of the Chinese 113th Infantry, operating five miles north of Mogaung, surrounded a Japanese company, while Cook’s guns hammered them. Fifty Japanese died from first blast alone. The Chinese finished off those who survived.The assault, was so ferocious that all the bunkers were overrun The reinforcements heartened Calvert for his own brigade was now a shell of its former self. The Lancashire Fusiliers and the King’s Liverpool had only 110 men, the South Staffords had 180 and the Gurkha Rifles had 230. He planned a fresh advance, this time aiming for the hamlet of Natgyigon, on Mogaung’s right flank, near the river. This area, Calvert believed, was the “key to Mogaung.” For the time, he chose the early hours of darkness on June 23rd a day which would go down in the annals of the 77th Brigade as the “stuff of legends.” The plan called for a mortar barrage of 1,000 bombs, in addition to shelling from the 75mm guns to cover the advance of the Chindits across the open ground towards Natgyigon. The Gurkhas were to move on the right, with the South Staffords on the left. Blaine’s Detachment and the Lancashire Fusiliers were in reserve. The objective was to capture the entire stretch of ground from the Mogaung Bridge to the train station, the latter of which the Chinese were to secure. Once the area was in Allied hands, the troops were to dig in while the reserve troops mopped up. In addition, Allied aircraft were to bombard the area before the start of the assault, which itself was timed to launch at about 3.10 am. In the dark, section commanders could be heard telling their men: “We attack Mogaung tonight and once we’ve taken it the Brigadier says we are through!” Later, during the attack, Calvert discovered the Chinese infantry had not captured the all-important train station, even as their American liaison officer insisted that they had. Calvert angrily pointed out that no, the Chinese had not, because enemy fire from that direction continued to pick off his men at the railway embankment.
The Gurkhas, moving along a wide right flank along the banks of the Mogaung River, headed for the railway bridge. Approaching the bridge, they came under heavy fire. Captain Allmand, by now suffering from trench foot as were most of the troops, moved forward to silence a machine gun firing on his men. He could barely run because of his affliction but advancing through the mud, he hurled grenades at the Japanese position. A burst of gunfire plunged into him. He fell, badly wounded. One of his Gurkhas, Sergeant. Tilbir Gurung pulled Allmand and another wounded NCO to safety. For this, Gurung was to get a Military Medal. Allmand’s own valor was to be recognized by a Victoria Cross. The South Staffords swept into Mogaung town. Resistance was heavy. Lt Durant of the South Stafford deployed his machineguns to rake Japanese positions with fire. Meantime, the flamethrowers were brought up. As they moved up past Durant’s positions, a shell burst exploded one, setting the man wielding it on fire. The man screamed and somehow shook off the flamethrowing unit from his back. Durant and some of his men rushed forward and rolled him into water in a nearby ditch. The Japanese had dug-in beneath the ruins of a brick house from where they were stubbornly holding the Staffords at bay. The rest of the flamethrowers moved in and sprayed the building. One Japanese, his clothes ablaze, leapt from his positions and tried to make a run for it. A scythe of gunfire cut him down. The rest valiantly held their positions and were burned to cinder. The Staffords, mopping up the, found the Japanese officer. He had shot himself with his revolver.
The Japanese had entrenched themselves at a strategically important building known as the Red House, which was well-protected with machine-gun nests. The advancing Gurkhas consequently ran smack into this killing zone, getting caught in a murderous crossfire and suffering heavy casualties. In response, Calvert threw his reserves into the fray and the Chindits also began to pummel the Japanese positions with mortars and machine-guns, which allowed the infantry to reach the all-important train station. Inflicting some 120 casualties and losing 60 dead and over 100 wounded, the Chindits then successfully captured all their objectives by noon. For the rest of the day, heavy fighting would continue as the Chindits dug in on their gained positions; but during the night, the Japanese would finally pull out, leaving the town to the shattered remnants of the 77th Brigade. Mopping up then continued until June 27, when Mogaung was declared void of Japanese. Though this was the first major town to be recaptured in Burma, Calvert lost over 250 killed and 500 wounded at Mogaung, which was more than any Chindit formation was prepared to take. This was also a bittersweet victory for Calvert because Stilwell would claim that the town had been taken by his Chinese troops, even though the Chindits had done most of the fighting.
Stilwill wrote in his diary on June 27th “Good news from Mogaung, We have it!” Then came a remarkable broadcast from Stilwell’s headquarters via the BBC “The Chinese had captured Mogaung”. There was no mention of the Chindits. Calvert was incensed. Colonel Li was appalled and apologized profusely. “If anyone has taken Mogaung it is your Brigade and we all admire the bravery of your soldiers.” Calvert, his anger against Stilwell unmitigated, sent a message to US headquarters “Chinese reported taking Mogaung. My Brigade now taking umbrage” this prompted Stilwell’s staff to scour the maps for the location of Umbrage. Meantime, congratulations poured in from Lentaigne, from “Scottie” Scott, from John Masters, and the other brigade commanders. Among the lot, there was one, from Derek Tulloch, which struck Calvert’s heart the most: “Wingate would have been proud of you.” After this defeat, and learning of the concurrent withdrawal of the 18th Division, Takeda’s 53rd Division would withdraw to the Sahmaw River line in early July, where it was also reinforced with the recently-arrived 119th Regiment.
Meanwhile over at Myitkyina, General Boatner had to order a stop to the attacks after June 18th because of the heavy casualties. For the time being, tunneling would be used to close with the enemy. On June 25th, however, Boatner would have a severe recurrence of malaria that would force him to abandon the frontlines. This led General Stilwell to appoint Brigadier-General Theodore Wessels in command of the Myitkyina Task Force on June 26th. Luckily for Wessels the situation started to improve after the fall of Mogaung, as Chinese troops there could now move up the railroad to connect with Wessels’ forces. This removed the recurrent menace of a Japanese drive from Mogaung, guaranteed reinforcements and the opening of a ground line of communications, and further eliminated one of General Minakami’s two bases from which supplies had trickled into the Japanese perimeter. Despite this, the only gains in the week of June 25th were a few hundred yards taken by the 150th Regiment and the 236th Engineers. Alongside this, Stilwell ordered the 1st Battalion, 42nd Regiment to penetrate through the Japanese positions towards Sitapur on June 28. They would drive deep into the Japanese defense system, leading Stilwell to hope this was the turning point; on receiving Japanese fire, it halted and dug in. Air supply was necessary.In response, Wessels dispatched some Marauder reinforcements. F Company, unaware it had lost its way and under an inexperienced commander, proceeded with a small point almost directly ahead of the marching column. The company commander at the head of the point met a small group of Orientals whom he took to be Chinese and who greeted him affably. The strangers then suggested he and his party lay aside their guns. At this point the commander realized that he had been ambushed and gave the alarm. The Japanese machine guns opened on his trapped column, inflicting heavy casualties. Some of his men made their way back to the Allied lines, but the company was never reconstituted and was broken up and distributed among the rest of Galahad. For his constant gallantry during a stubborn eight-hour rear-guard action, which permitted the survivors to extricate themselves from ambush, Private first class. Anthony Firenze of New Galahad received the Distinguished Service Cross. Wessels then planning to launch a set-piece attack to capture a stretch of the Sumprabum Road.
Over in the Yunnan front, Colonel Matsui’s 113th Regiment had successfully relieved the pressure from Longling by mid-June. General Matsuyama further ordered him to maintain the offensive while he continued to reorganize his forces. Though Matsui managed to seize the Tiechanghe pass on June 21st, most of his attacks would end up in nothing. In the north, the 20th Army Group launched simultaneous attacks against Qianshuang and Gudong on June 18th. This finally forcing the Japanese to retreat in disorder towards Tengchong by June 22nd. With the fall of Qianshuang, the Japanese had been forced to abandon the upper Shweli valley, and were now moving in some disorder toward Tengchong over three excellent trails. In Qianshuang, they left behind large quantities of ammunition and a few pieces of artillery, suggesting a disorganized withdrawal. 150 dead Japanese were found in Qianshuang itself; more than 300 Chinese gave their lives for the village. South of Qianshuang, the Japanese hastily destroyed their pontoon bridge to slow the Chinese pursuit. On reaching the Qianshuang-Baifen-Gudong line, the 20th Army Group had wrested 4000 square miles from Japanese control in forty days of fighting. The advance had been made over the precipitous ranges of the Kaolikung Mountains in an almost constant rain, a downpour sometimes heavy, sometimes light, rarely abating, and always turning to fog and sleet in the higher altitudes. More than 150 coolie supply porters fell to their deaths from the narrow, slippery trails that snaked precariously over the mountains.
On June 25th General Wei received a personal order from Generalissimo Chiang Kai-Shek to take Teng-chung. A few days later, th 20th Group Army, though delayed by the need to rebuild bridges over each of the swift mountain streams that crossed its advance, had pressed the Japanese rear guards back to the hills that surrounded Teng-chung at a distance of two to three miles from the formidable walled town itself. Meanwhile, the Fourteenth Air Force was trying to soften Teng-chung by daily attacks with bombs and machine-gun fire. The outer defenses of Teng-chung were pillboxes covering every avenue of approach, supported and covered by the 6,500-foot-high, fortified mountain peak of Lai-feng Shan, "The Place Where the Birds Come." Here were 600 or more Japanese with most of the garrison's artillery. Teng-chung itself was girdled by a massive wall of earth that in some places was forty feet high and sixty feet thick at the base, faced throughout with great slabs of stone. Chinese necromancers had carefully laid out the wall in a great square to cut the cardinal points of the compass. Each side had a gate, and each gate now had a Japanese command post, while Japanese machine guns and rifles swept the approaches to the wall, its face, and its parapets. Within the city were about 2,000 Japanese. In all, Colonel Kurashige, who had defended the Kaoli-kung mountains, had about 1,850 Japanese, a heavily reinforced battalion combat team built around the 2nd, 148th regiment. Kurashige's orders were to hold Teng-chung until the Chinese threat to Lung-ling passed
Over at Longling, Matsui saw the arrival of some reinforcements on June 22nd that would allow him to continue his counteroffensive. Making repeated night and day attacks, the Japanese would be able to penetrate the enemy positions on June 24. Matsuyama then directed him to exploit towards Bengmiao and Huangcaobacum; yet a heavy raid by 24 B-25s and the arrival of the 1st Division would manage to halt the Japanese attempt to exploit their success, with Mitsui only securing the area northwest of Bengmiao by July 1st. The next day, Matsuyama then suspended the counteroffensive because of heavy casualties and he could see the enemy were strengthening their positions. In the meantime, Major Kanemitsu’s Lameng Garrison was successfully holding off against a siege by three divisions since June 4th, though the Chinese would only launch unsuccessful attacks in regimental strength during this period; and to the southeast, the Pingda Garrison was also successfully repelling the small enemy attacks against them in spite of being cut off and disease-ridden. That is all for the Burma front today as we now need to head over to the Biak front.
After the arrival of two battalions of the163rd Regiment for reinforcements, General Fuller planed a two-pronged attack against Mokmer Drome, with the 186th Regiment advancing west over the inland plateau while the 162nd Regiment resumed its attack west along the coast. On the morning of June 1, in preparation for the offensive, Colonel Newman’s 3rd Battalion therefore left Bosnek and marched north over the coastal ridge, with the 2nd Battalion also moving from Opiaref to join them. By 11:00, both battalions successfully set up defensive perimeters; yet their preparations would be interrupted abruptly in the afternoon as Colonel Kuzume directed his 1st Battalion to attack the positions held by Company K. These Japanese, who were supported by machine guns and mortars emplaced northwest of the trail crossing, continued attacks until 5:00, when a platoon of Company K, by a flanking movement, forced their withdrawal northward. Company K and two platoons of the Antitank Company remained at the trail crossing for the night. Company I was moved forward to K's left and left rear, and Company L extended K's perimeter east along the main road toward the surveyed drome. Battalion headquarters and Company M stayed near the strip's western end. The 121st Field Artillery Battalion, the Cannon Company, the 2nd Battalion, regimental headquarters, the attached engineers, and the tanks remained near the center of the airfield.
Thankfully, the Americans would manage to repel the assaults and would ultimately force a Japanese withdrawal via a bold enveloping maneuver. But the Japanese would return after midnight. The first part of the night passed without incident, but at 3:30 the entire area held by the 3rd Battalion, 186th Infantry, flamed into action. About a company and a half of the 1st Battalion, 222nd Infantry, moved from the south against the semicircular perimeter held by Companies I, K, and L, having outflanked the 3rd Battalion on the west. Simultaneously, other elements of the 1st Battalion attacked from the northwest, attempting to drive a wedge between Companies L and K. Under the support of mortar and machine gun fire from both the northwest and southwest, the encircled Japanese desperately tried to fight their way north. Four hours of confused hand-to-hand fighting, marked by the use of bayonets, machetes, and grenades, ensued. At daylight a count revealed that 86 dead Japanese were within and around the 3rd Battalion's perimeter. The dead included the commander of the 1st Battalion, 222nd Infantry. Losses to the American unit were 3 men killed and 8 wounded.
After dealing with the threat, Newman resumed the westward advance at 9:00 on June 2nd. The 1st and 3rd Battalions, supported by five tanks and an antitank platoon, were to advance abreast, while the 2nd protected the right flank by patrolling north of the main road. The 121st Field Artillery Battalion was to provide continuous close support and was to displace forward with the infantry. Neither artillery nor air bombardment seems to have been provided for or delivered prior to the attack. However, both the 121st and 146th Field Artillery Battalions were registered on targets north and west of the 186th Infantry. Air support was available from Wakde Island upon call.
The 1st Battalion, 186th Infantry broke camp at its beach defense area at 8:00 on June 2nd and moved north over the ridge to join the rest of the regiment. The 1st Battalion, 222nd Infantry, had made no serious attempt to stop the 186th Infantry's progress westward because the inland plateau was nearly indefensible and because the battalion would have been decimated in battle with the superior strength of the reinforced American regiment. The 1st Battalion was withdrawn from the surveyed drome area, initially in preparation for counterattack against the Bosnek beachhead. While no such counteroffensive was mounted, the withdrawal of the 1st Battalion at least had the advantage of keeping the unit intact. The American advance would thus be opposed by the 10th Company, 222nd Regiment; the 3rd Company, 36th Division Sea Transportation Unit and some other naval and engineer units. The 1st and 3rd Battalions then advanced with two companies abreast against scattered but determined opposition from elements of the 1st Battalion, 222nd Infantry. Small enemy patrols aimed machine gun and rifle fire at the advancing American units and held their positions until killed or dispersed by tank or artillery fire. Most of the enemy parties were located on the north flank and apparently many of them had been driven westward out of the cave and garden area north of the surveyed drome by fire from the 121st Field Artillery Battalion, which destroyed Biak Detachment headquarters installations in that area. By nightfall the 186th Infantry had killed 96 Japanese and had itself lost 6 men killed and 10 wounded. The unit halted shortly after 1600 and began digging in at a point about 600 yards northeast of the day's objective. The advance had carried the regiment west until it was almost abreast and north of the 162nd Infantry, at the Ibdi Pocket. The latter had attempted to move west along the coast during the day, but it would be unable to dislodge the Japanese from the Ibdi Pocket, ultimately having to attach its 2nd Battalion to the 186th.
The addition of the 2nd Battalion, 162nd Regiment to the 186th Regiment helped to complicate the supply problems of the troops on the plateau. No water had yet been found inland. Heat and humidity were intense, and thick scrub growth, about 12 feet high, stopped any breezes. Despite the best efforts of Company B, 116th Engineers, the supply road could not be repaired fast enough to keep pace with the advancing infantrymen. Water had to be brought around from Bosnek via Opiaref to the forward units, and there were not enough water trailers nor 5-gallon cans available to supply all the water needed. At night each man received only one canteen of water for the next day, an inadequate amount under the conditions which prevailed inland. The water situation and the necessity for hauling all other supplies north through Opiaref did more to delay the 186th Regiment’s progress westward than did the opposition of the 1st Battalion, 222nd Regiment.
Meanwhile Kuzume’s only support so far had been some air raids carried out by the depleted 23rd Air Flotilla and 7th Air Division. By late May, the 23rd Air Flotilla had only twelve fighters and six medium bombers at Sorong and the 7th Air Division had four large bombers, 20 medium bombers and three fighters. Both units threw what strength they could muster into attacks on the enemy landing force. On May 27th four Army heavy bombers and nine Navy fighters carried out a daylight attack against fierce air opposition, all but four fighters failing to return. Kuzume would need more than that to launch a determined attack that would succeed in pushing the enemy back into the sea. Consequently, on May 29th, General Numata and Admiral Senda had requested the immediate commitment of fleet and air strength into the Biak battle. They both relayed this message “The enemy apparently found the difficulty of rapid occupation of the airfield sector. The enemy will change, in all probability, its policy to occupy the whole island of Biak after the arrival of reinforcements, securing its present positions with landed units for a while. The officers and men on Biak Island are firm in their resolution to crush the enemy. However, our operations are severely restricted by the uncontested superiority of the enemy's feet and air units. The Biak Detachment, which is making every effort in destroying the confronting enemy, request for further support by the army and navy units concerned. We believe that the immediate commitment of our air forces and, if possible, some fleet units would give us a splendid opportunity to turn the tide of battle in the whole Pacific area in our favor.“ This finally convinced Admiral Toyoda to send reinforcements to the island.
To counter the Allied advance to Biak, the IJN dispatched from one third of its available naval land-based air strength from the Central Pacific to reinforce the 23rd Air Flotilla in western New Guinea. On May 28th 70 carrier-type fighters, 4 reconnaissance bombers, and 16 medium bombers were dispatched to western New Guinea. Another group of planes, comprising 48 fighters, 8 reconnaissance aircraft, and 20 bombers, were sent to western New Guinea and Halmahera from the Carolines on or about May 31st. On 29-30th May the flotilla carried out fresh attacks on the Biak landing force. On May 29th, sixteen medium bombers attacked the enemy fleet in the sea near BIAK Island before daybreak of that day, yet none of them returned. Furthermore, in a daylight attack on the same day, four Zero fighters strafed BIAK Island. None of them returned to the base either. On May 30th, the unit of the Zero fighters of the Navy again fired upon enemy ships in the sea off Mokmer. The damage on the enemy ships was not confirmed. However, the unit reported that they fought four P-38s and four B-25s of the enemy and shot down two B-25s above BIAK Island.
Also as part of Operation KON, a huge task force under Admiral Sakonju, which included the battleship Fuso, four cruisers and eight destroyers, was to transport Major-General Tamada Yoshio’s 2nd Amphibious Brigade towards Biak. Additionally, it was decided to move three infantry companies of the 35th Division from Sorong to Biak by barge. Sakonju’s convoy finally left Davao on the night of June 2nd.
In connection with KON Force's advance, the Japanese had planned heavy air strikes against Biak which were to be carried out by the recently reinforced 23rd Air Flotilla and the few army aircraft which remained at bases within range of Biak. Between 1645 and 1700 on 2 June, from eleven to fifteen Japanese planes bombed Allied positions on Biak, causing a few casualties and some light damage. Seven of these planes were shot down by shore-based anti-aircraft weapons, while guns aboard Seventh Fleet ships lying off Bosnek accounted for at least one more. Later during the same night, a few more enemy planes dropped some bombs harmlessly on and near Owi Island. Still more approached Biak during the night, causing many red alerts but not dropping any bombs. The next night, that of 3-4 June, no Japanese planes attacked Biak, although an unknown number bombed Owi Island without causing any damage or casualties. Again, however, enemy aircraft flew many reconnaissance flights around Biak, causing an almost continuous red alert until the early morning hours of 4 June.
Early on the morning of June 3rd, at a point just east of the Talaud Islands, between Mindanao and Morotai, a 7th Fleet submarine sighted the Transport and 1st Screening Units and was in turn sighted by ships of the latter organization. Alongside this 7th Fleet PB4Y's, operating from Wakde Island, kept the Japanese vessels under surveillance the rest of the day, reporting that the course and speed of the enemy ships could bring them into range of Biak during the evening of June 4th. Their discovery by Allied aircraft so far from Biak apparently had not been anticipated by the Japanese, who later reported that they had not known Allied aircraft were capable of such long-range reconnaissance. Nevertheless, the three KON Force elements steamed on toward Biak, probably hoping that friendly aircraft might drive off the Allied reconnaissance planes and also protect the sea approaches to Biak.
To further muddy the situation, Sakonju received false reports that a strong American carrier group was approaching the waters east of Biak. Admiral Kinkaid had indeed dispatched a special task force to deal with this threat, yet the warships could only arrive off Biak on the night of June 4th and didn’t include any aircraft carrier. Nonetheless, knowing that he had been discovered and unwilling to risk so many ships under these circumstances, Sakonju would have to suspend the reinforcement run and turn back to Davao and Sorong.
When the Japanese called off KON on June 3rd, the Transport and the 1st and 2nd Screening Units were a little over 500 miles northwest of Biak and about 250 miles east-southeast of the Talaud Islands. At this point, the three forces were reorganized. The Transport Unit, accompanied by the three destroyers of the 1st Screening Unit, changed course for Sorong, while the 2nd Screening Unit and the two heavy cruisers of the 1st turned back toward Davao, which they probably reached late on June 5th. Of the ships moving to Sorong, the Fifth Air Force claimed to have sunk one destroyer and damaged at least two others. The Transport Unit and the 1st Screening Unit's three destroyers arrived safely at Sorong during the evening of June 4th. The Detached Unit, which had been moving toward Biak from Zamboanga on an independent course far to the west of the other three sections of KON Force, had also changed its direction during the night of 3-4 June, and reached Sorong sometime on the 4th. At Sorong the Transport Unit unloaded the 1,700 men of the 2nd Amphibious Brigade. The six destroyers of the Transport and 1st Screening Units then proceeded southwest to Ambon where they refueled. The Transport Unit's one heavy cruiser and one light cruiser sought shelter in Kaboei Bay, Waigeo Island, about 60 miles northwest of Sorong. On 6 June the heavy cruiser Aoba was attacked there by fifteen B-24's of the Fifth Air Force. First reports were that at least two hits were scored on the cruiser, but it was later learned that the ship suffered no damage. Instead, it was able to take part in a second KON Operation.
Back over at Biak, Newman resumed the advance westward on the morning of June 3rd, making painfully slow progress because of the difficult terrain and lack of adequate supply lines. Meeting no opposition, they would finally dig in half a mile from the point at which the main ridge left the coast and turned inland near Mokmer. That day, however, Fuller learnt about the possible enemy naval attack, so he decided to halt any offensive actions for the moment. On June 4th, upon learning that no enemy carriers were in the Biak area, Sakonju was again ordered to prepare to run the American blockade, this time bringing the bulk of the 2nd and 3rd Battalions, 219th Regiment. There would be two naval groups, the first was the Transport Unit, containing three destroyers which had been part of the first KON Operation Transport Unit. The second section was the Screening Unit, also comprising three destroyers. For the second KON Operation there were two detached units, the 1st had one heavy and one light cruiser while the 2nd Detached Unit included the small craft and patrol boats which had put into Sorong at the end of the first KON. The three destroyers of the Transport Unit were each to embark 200 infantrymen at Sorong. In addition, the destroyers of either or both the Transport and Screening Units were each to tow to Biak one landing barge crammed with troops, probably 30 to 50 men to a barge.
After two quiet nights, meanwhile, Newman decided to send three battalions forward toward the north-south section of the main ridge northwest of Mokmer on June 5th. Warned by the regimental commander that it was important to secure a foothold on the ridge before the Japanese could deny it to the 186th Infantry, the three assault battalions started westward about 8:00 on June 5th. Lack of water again slowed the advance. No water had been received in the forward area since the morning of the 4th, and Colonel Newman had ordered the troops westward against the advice of his staff and battalion commanders. About noon, however, a heavy rain fell. The regimental commander ordered all troops to halt, catch the rain in ponchos, and fill their canteens. "Had it not been for this lucky break, we would undoubtedly have had to halt in midafternoon." As events turned out, no Japanese opposition was encountered, and by 1500 the 3rd Battalion, 186th Infantry, was within 500 yards of the main ridge. Although Newman and General Doe then wanted to secure the dominating terrain north and northwest of the airfield, they would receive direct orders from Fuller to immediately seize Mokmer Drome and a beachhead on the coast directly south of that strip. Throughout the morning of June 6th the 186th Infantry directed most of its efforts to bringing supplies up to the forward units. Almost the entire 2nd Battalion was engaged in hand-carrying supplies to the 3rd Battalion atop the ridge, while the latter unit sent patrols toward Mokmer Drome seeking good routes of approach to that objective. About noon Colonel Newman reported to task force headquarters that no good route had been found and that supplies, especially the ever-needed water, had not been brought forward in sufficient quantities to allow a regimental attack to be launched that day, and he therefore recommended that the attack be postponed until June 7th. General Fuller approved this suggestion. The lack of supplies and water would delay the attack, however, though the 3rd Battalion would be able to move down the west side of the main ridge to take up positions along a line of departure for the next morning's attack.
To support the infantry attack, on June 7th, a thirty-minute artillery concentration began at 7:00 that morning. The 146th, 205th, and 947th Field Artillery Battalions, from positions along the coast to the east, were registered on targets in the airfield area ready to support the advance, but most of the firing was undertaken by the 121st Field Artillery from its location behind the 186th Infantry. While the artillery fired on Mokmer Drome and along the low ridge between that field and the 186th Infantry, Fifth Air Force bombers attacked the Borokoe Drome area and also struck some targets along the low ridge. The airfield was only occupied by the 108th Airfield Construction Unit, which immediately fled the area because of the heavy bombardment. Newman’s 1st and 3rd Battalions advanced south encountering no resistance as they crossed Mokmer Drome and reached the beach.
When, on 5 June, the 186th Infantry had reached the crest of the main coastal ridge, it had been on the left rear of the Japanese defenses on the low ridge and terraces above Mokmer Drome. Thus, the regiment had been in a favorable position to take these defenses from the rear. But in its move to the airfield, the 186th Infantry had bypassed the Biak Detachment's principal defensive positions. The bypassing had not been intentional. Colonel Newman had instructed both leading battalions to halt on the low ridge, reconnoiter along it in both directions, and report on Japanese defenses before moving on. According to Colonel Newman: "I received a negative report from both battalions, and ordered the movement to the airdrome. Evidently, the right battalion had failed in this patrolling effort."
Instead, the 186th had captured its main objective, but now found itself surrounded by Kuzume’s strongest defenses. The Japanese immediately began to pound the new American perimeter, with an artillery duel soon erupting. By nightfall, it had become impracticable to supply the 186th Regiment over the inland plateau road, which ended on the east side of the main ridge. From that point, all supplies would have to be hand-carried to Mokmer Drome and supply parties would be endangered by Japanese patrols, a few of which moved in behind the 186th as the regiment reached the beach, so the 3rd Battalion, 163rd Regiment would be dispatched to push over the inland plateau and protect the parties. Overwater supply was also attempted, yet as the first boats approached the shore they were greeted by machine gun and rifle fire from Japanese whom the 186th Infantry had not yet cleaned out of caves along the water line in front of Mokmer Drome. The small craft returned the fire, but were finally forced to withdraw. The 186th Infantry, according to Colonel Newman, was "glad to see them withdraw since they had our troops running for cover." At 2:00 another attempt was made to land supplies at Sboeria. The three LCM's managed to put their tanks ashore in the face of continuing Japanese fire, but accompanying LCT's were driven off by Japanese artillery. Two of the LCM's were so damaged by enemy fire that they could not fully retract their ramps and had to proceed the nine and a half miles back to Bosnek in reverse. Plans were made to effect all delivery of supplies and evacuation of casualties at night until the enemy fire on the Sboeria beachhead could be neutralized. The tanks which had been landed lumbered along the shore road fronting Mokmer Drome, destroying several small bunkers along the beach. Then they wheeled toward the low ridge north of the airfield, taking under fire a Japanese 75-mm. mountain gun and a 20-mm. piece which had opposed their landing. These two weapons were silenced. Moving cautiously northwestward from the field along a road which crossed the low ridge, the tanks destroyed two large pillboxes. Alongside this, Fuller sent two companies of Haney’s 3rd Battalion to land on the Parai Jetty in order to outflank the Ibdi Pocket, which the 162nd had been unsuccessfully attempting to dislodge since the start of the month. But June 7th would also see the start of Operation KON’s second attempt.
After rendezvousing off Misoöl Island that morning, Sakonju instructed his 8 destroyers to proceed to Biak. Air cover was to have been provided by planes of the 23rd Air Flotilla. But the cape area was being patrolled by Allied aircraft on June 8th and, about 1:30, the 23rd Air Flotilla cover of six planes was shot down or driven away by 5th Air Force P-38's.
Finding the air now free of enemy planes, American B-25's dived to the attack th convoy, reporting the convoy as 2 light cruisers and 4 destroyers. Initially, it was claimed that 1 destroyer was sunk, 2 were left sinking, and the fourth was damaged. A few days later, destruction was reassessed as 4 destroyers sunk and 2 light cruisers chased to the northwest. These claims were exaggerated. One destroyer, the Harusame, was holed by a near miss and sank rapidly, the bulk of its crew being saved. Another destroyer was damaged by a bomb and took some water; two others were slightly damaged by strafing. Neither speed nor navigation was impeded for any of the three. The two light cruisers reported by the Allied planes were, of course, the other two destroyers. These two might have taken some evasive action by heading northwest for a short time, but as soon as the Harusame crew had been rescued and the Allied planes had disappeared, the convoy reformed and continued on toward Biak.
The convoy reformed and continued on toward Biak, undeterred by reports of strong enemy elements in the area. By nightfall, however, it was on a collision course with the cruisers of Admirals Crutchley and Berkey. At about 6:00 on the 8th, the Transport and Screening Units received a report from a Japanese aircraft that an Allied naval force comprising 1 battleship, 4 cruisers, and 8 destroyers was moving west at high speed from an undesignated point east of Biak. This report was at least partially correct. The Allied task force which had been formed on June 3rd had again assembled on the 8th, having been alerted by reports of the air-sea battle off the Kaap de Goede Hoop. But the Japanese convoy commander apparently took this air reconnaissance report with at least one grain of salt--had not similar information received on June 3rd proved inaccurate? The Transport and Screening Units steamed on, despite the fact that the Kaap de Goede Hoop action had put the force behind schedule. At 11:30 the two enemy groups were approximately forty miles off the north coast of Soepiori Island, ready to turn southeast toward Korim Bay, on the northeast side of Biak. Minutes later a destroyer in the van sighted the Allied task force heading northwest around Biak. The convoy commander quickly realized that he was badly outnumbered and decided that discretion was called for. The Japanese convoy slipping towards the Mapia islands, seeing the allied destroyers failing to pursue them. Yet that is it for Biak for now as we now need to head over to the Wakde-Sarmi front.
General Sibert was preparing to resume the westward offensive. By June 14th, the 20th Regiment had relieved the 158th at the Tirfoam River; and although Sibert wanted to complete unloading of his remaining units before sending the 20th to push westward, General Krueger ordered him to start an immediate offensive on June 18th. Now, however, they were up against almost the full strength of General Tagami’s 36th Division. Company B pushed on toward the village at the entrance to the defile between Lone Tree Hill and the eastern nose of Mt. Saksin. This advance was greeted by a hail of fire from Japanese automatic weapons emplaced in the defile--fire reminiscent of the opposition encountered by Company B, 158th Infantry, at the same place more than three weeks earlier. The 20th Infantry's Company B tried to outflank the enemy position to the south but was halted by intense Japanese machine gun fire. Tanks sent forward to aid the infantry were unable to reach the enemy guns because the terrain was impassable to tracked or wheeled vehicles, which could scarcely negotiate the rough road, let alone the thick jungle and rising ground to the south. Late in the afternoon Company A was sent forward to Company B's position, but both units encountered heavy fire and soon lost contact with the rest of the 1st Battalion. The two companies remained for the night in an isolated perimeter near the village and about 400 yards west of the main body. The 3rd Battalion had moved north off the coastal road during the morning, and late in the afternoon it had established a perimeter extending south 200 yards from the beach along the east bank of the Snaky River. The battalion had encountered little opposition during the day, but patrols which had crossed the Snaky before dark reported finding many Japanese defensive positions on the eastern slopes of Lone Tree Hill. A gap which existed between the 1st and 3rd Battalions was partially filled just before nightfall by elements of the 2nd Battalion, which were sent forward late in the afternoon. Casualties during the day were four killed and twenty-eight wounded. The 1st and 3rd Battalions, 1st Infantry, moved across the Tor River in the morning of June 20th and took over the positions in the vicinity of Maffin No. 1 vacated by the 20th Infantry. The 2nd Battalion, 1st Infantry, assumed responsibility for the protection of the bridgehead across the Tor.
The following morning, Sibert then directed his units to patrol extensively in order to locate enemy strong points on and around the hill. Thanks to the information gathered, the 3rd Battalion would attack towards Rocky Point in the afternoon. At the top of Lone Tree Hill was a stretch of rough but generally level ground lying mostly along the western part of the hill. This flat ground, about 700 yards long north to south, was shaped like a crude dumbbell. At its northern end, the level area was about 300 yards wide. It narrowed at the center of the hill to less than 100 yards but broadened again on the south to a width of about 250 yards. There were many coral outcroppings, potholes, and small crevices, while on the north the hill terminated in a very rugged prominence called Rocky Point. This terrain feature, which extended into Maffin Bay from the central mass of Lone Tree Hill, was about 300 yards wide east to west. Its northern face was not as heavily overgrown as the rest of Lone Tree Hill. Although Rocky Point's northeast slope was steep, foot troops could climb that face with more ease than they could approach the top of Lone Tree Hill from most other points. A deep ravine ran southwest into the central mass of Lone Tree Hill from a sandy beach on the east side of Rocky Point. The floor of the ravine varied from 20 to 30 yards in width and its nearly vertical western wall was 40 to 50 feet high. Both sides were honeycombed with natural or man-made tunnels, caverns, and small caves, most of which were connected with each other by underground or deeply defiladed passages. Some caves reached a width of 40 feet, a depth into the hillside of 50 feet, and a height of 20 feet. The ravine terminated on the eastern slope of Lone Tree Hill in a steep grade at the narrow central portion of the hilltop.
At 1:45pm, after a fifteen-minute artillery and 4.2-inch mortar preparation, one company moved across the Snaky River, immediately finding the twenty-foot cliff along the eastern side of the shelf which lay between the Snaky River and the central mass of Lone Tree Hill. The morning patrols had not, apparently, reported the existence of this cliff, and naturally it was not known that Japanese defenses were established along it. Machine gun and rifle fire from the 1st Battalion, 224th Infantry, soon pinned down the 3rd Battalion's leading platoon. The company commander quickly sent part of his unit northward to find the Japanese left flank. Moving around the northeast end of the shelf, this group discovered the beach entrance to the deep ravine between the western side of the shelf and Rocky Point. Progress into or across the ravine was impossible in the face of the intense Japanese small arms fire which greeted the advancing American unit. Company B, 6th Engineers, then in the forward area to cut a road from the mouth of the Snaky River to Rocky Point, was brought up to the ravine to help clean out caves and crevices with flame throwers and demolitions, but could not reach the enemy positions through the continued machine gun, mortar, and rifle fire. Infantry bazooka squads also tried to blast the Japanese out of their caves but failed when their ammunition ran out. Since there was no time to bring additional rockets forward before dark, all elements of the 3rd Battalion and the engineer company were withdrawn to the east bank of the Snaky River for the night. The 20th Infantry was to continue the assault on the morrow with the 3rd Battalion moving against Lone Tree Hill from the northeast, the 2nd Battalion in reserve, and the 1st Battalion remaining in its holding position.
On the morning of June 22, after a heavy air and artillery concentration on Rocky Point, the 3rd Battalion once again attacked northwest with Companies K and I, successfully driving the Japanese back into their caves to reach the top of Lone Tree Hill just south of Rocky Point. Meanwhile, another two companies had attacked southwest to force their way up the southeast slope of the hill; but subjected to heavy machine-gun fire, they would have to withdraw and march north to join Companies K and I. The 2nd Battalion also moved forward and took positions to the south of the 3rd Battalion. Worried about the American gains, Colonel Matsuyama personally led two companies in the afternoon to fall on the 3rd Battalion’s perimeter with suicidal fury. Confused fighting, sometimes hand-to-hand, continued well into the night, with Matsuyama himself getting shot on the thigh. Yet this attack would successfully position the Japanese companies on the rear of the 2nd and 3rd Battalions, thus cutting them off from regimental headquarters. Matsuyama also recalled his 2nd Battalion from the Maffin area, so he would employ these reinforcements to attack Sibert’s 2nd Battalion on June 23. At dawn on the 23rd Japanese troops, some of whom were using American weapons and wearing parts of American uniforms, attacked the 2nd Battalion, 20th Infantry, from the deep ravine. The battalion initially held its fire, thinking that the enemy force might be a friendly patrol, and the Japanese were able to advance to within fifteen yards of the battalion lines before being recognized. It was an hour before the results of this error could be corrected--an hour during which both the 2nd Battalion and the Japanese suffered heavy losses. The hour ended with an enemy retreat.
Isolated, the 2nd Battalion then decided to withdraw and march north towards the 3rd Battalion’s perimeter at the top of the hill, getting harassed all the way by Matsuyama’s forces. During the night, the Japanese launched a banzai charge against the perimeter, getting very close to retaking Lone Tree Hill but suffering heavy casualties in the end. Upon learning that his battalions were cut off, meanwhile, Sibert decided to outflank the hill by a shore-to-shore maneuver and then continue the attack from both west and east. Accordingly, Companies K and I of the 1st Regiment boarded ten LVTs on the morning of June 24th and moved to the beach just west of Rocky Point, under the protection of the 6th Reconnaissance Troop. Both companies would land successfully by midday against strong Japanese fire, though they would be rapidly pinned down on the narrow beach. Thankfully, Sibert also landed four tanks two hours later to secure the beachhead. This diversion would allow the 2nd and 3rd Battalions, 20th Regiment to begin clearing the Japanese from the many caves and crevices on Rocky Point, the deep ravine east of the point, and the hilltop plateau, further securing the supply route up the hill.
By nightfall, no enemy counterattack developed, as Tagami had instead decided to withdraw the 224th Regiment to the Hill 255-Mount Saksin line while the 223rd Regiment retreated behind the Woske River. Thus Matsuyama’s resistance in the area weakened and the Americans were finally able to clear Rocky Point. The next day the 2nd and 3rd Battalions, 20th Infantry, continued clearing Rocky Point, the deep ravine, the northern part of the hilltop plateau, and the eastern shelf, where a few scattered Japanese still held positions along the twenty-foot-high cliff. Flame throwers, demolition charges, bazookas, and hand grenades all proved successful in eliminating Japanese resistance and sealing or clearing caves and crevices. The task was easier on the 25th, for the Japanese slowly gave up the fight and were killed or sealed off in their caves. Casualties continued to mount, the 2nd Battalion, 20th Infantry, had only about two hundred effectives by the end of the day but many of the losses were not due to Japanese action. Many men were evacuated over the now secured supply route to the top of the hill as they fell from exhaustion or became sick. On the beach west of Rocky Point Companies I and K, 1st Infantry, had little success in expanding their beachhead. The tanks proved useless in the area and were therefore withdrawn to Maffin No. 1. The two infantry companies, pinned down during the morning, kept up a continuous mortar barrage against Japanese positions in the swamp to the south, against the western cliff of Lone Tree Hill, and, when certain such fire would not endanger troops atop the hill, against the northwest corner of Rocky Point. This mortar fire, coupled with the operations on the plateau, began to have the desired effect during the afternoon, and Companies I and K were able to push their defenses beyond the narrow beachhead slightly southward and westward and toward the shore beneath Rocky Point. Once or twice during the afternoon, patrols were able to reach the top of Lone Tree Hill from the northwest corner of the point and established contact with 20th Infantry units. Late in the afternoon Company M, 1st Infantry, operating from the east side of the point, managed to push a patrol around the shore to establish contact with Company K. Though Companies I and K could find little tangible evidence of the results of their operations, they had actually wiped out the 223rd Infantry's defense force in the area just west of Lone Tree Hill. By dusk on the 25th, it had become obvious that the combined efforts of the 3rd Battalion, 1st Infantry, and the 2nd and 3rd Battalions, 20th Infantry, had either cleared out the northern half of Lone Tree Hill or had forced the Japanese to withdraw. The latter conclusion was the more nearly correct. The 36th Division decided on 25 June to withdraw the bulk of the Center and Right Sector Forces west of the Woske River and establish new defensive positions, thereby keeping the 223rd Infantry, the bulk of which had not been committed to action in the Lone Tree Hill area, more or less intact. Only the remnants of the 224th Infantry were to remain east of the Woske, and they were to withdraw into rough terrain southwest of Mt. Saksin. At nightfall on the 25th, General Sibert estimated that his three forward battalions had lost approximately 140 men killed and 850 wounded and evacuated, including those who had to be sent back to the rear because of wounds, sickness, heat exhaustion, or psychoneurotic disorders. Known Japanese dead in the northern part of the hill numbered 344, but it could not be estimated how many more had been thrown over the west cliff, sealed in caves, or carried off by withdrawing remnants of the Japanese defense force. According to Japanese sources, the Japanese had lost about 500 men killed and another 300 wounded in the Lone Tree Hill-Hill 225-Mt. Saksin area.

The Chinese were accredited with the fall of Moguang despite the Chindits taking the lionshare of the fighting. Things were advancing very well for the allies in the new Biak front. As for the battle for Lone Tree Hill, it was a costly one, and not one the Americans or Japanese would soon forget.

- 132 - Pacific War - Landing against Biak, May 28 - June 4, 1944
28 mei· The Pacific War - week by week
Last time we spoke about the Siege of Myitkyina. General Vinegar Joe made huge gains in northern Burma. Myitkyina’s airstrip was taken, now the main town was under siege. The Japanese resistance around Kamaing was greatly reduced. However setbacks were also seen, such as the Chindits abandonment of the Blackpool stronghold, prompting Stiwell to toss a new attack at Mogaung. Likewise American officers embedded with the Chinese units were sending reports of how the Chinese were suffering very heavy casualties and utilizing far too much ammunition for their objectives. Regardless, it seemed the Ledo Road to China was going to pan out. Calvert chose a new stronghold location, this time at Lakum, where his Chindits faced heavy resistance. Over on New Guinea, the allies were advancing west of their new beachheads to assault Lone Tree Hill. Soon assaults against Arare and Biak would also be made.
This episode is the Landing against Biak

In the last episode, plans were made for an amphibious assault against Biak, yet there were some hiccups. The Hurricane Task Force staged at Humboldt Bay, were facing issues with terrain. Terrain considerations forced most of the task force to assemble on the southern of the two sand spits dividing Humboldt and Jautefa Bays. On this spit the beach had a steep slope which made it impossible for more than a very few LST's to be held against the shore line long enough to load bulk stores. The LST's had to beach on the northern spit, where clearing and salvage after the fires and explosions which had ravaged that beach during the early phases of the Hollandia operation had not been completed. In addition, the northern spit was being used to unload supplies destined to be used at Hollandia, to load supplies being sent to the Tornado Task Force at Wakde-Sarmi, and to unload cargo for the Hurricane Task Force. No road connected the northern and southern sandspits. Consequently, most of the supplies and equipment, as well as many of the troops, had to be transported by water from the southern to the northern loading area. There were only a few LCT's available for this work and only by working twenty-four hours a day, were all the troops and supplies transported to the loading beach in time for departure on the 25th.
Finally, General Fuller’s task force would depart the bay on the evening of May 25th, covered by Admiral Fectheler’s cruisers and destroyers. Taking the most direct route, the convoy would be able to arrive off Biak on the morning of May 27th. At the time, Biak was held by the Biak Detachment, under Colonel Kuzume Naoyoki. It consisted of the 222nd Regiment; the 19th Guard Unit; and some rear echelon, service, and construction units. There were 10000 IJA personnel, 4000 were combat troops in total and 2000 IJN personnel, 125 were combat troops in total. In view of the intense enemy concentration on the Sorido-Mokmer airfield sector, Colonel Kuzume decided on May 22nd to shift the operational center of gravity of the detachment to the west. The 1st Battalion, 222nd Infantry, was relieved of its mission in the sector east of Opiaref and sent to replace the naval garrison unit in the Bosnek sector. The naval troops were, in turn, shifted westward into the Sorido airfield sector, while the tank company was brought over from Arfak Saba and assembled in the area northwest of Mokmer airfield. Although most of the Japanese efforts had been directed to the construction of airfields, Kuzume had ably managed to build a system of strong cave positions.
In this amphitheater-like terrain and along the low ridge, both of which were covered with thick growth, the Biak Detachment emplaced many field artillery and antiaircraft weapons. There were also many automatic weapons and a few mortars. All these weapons were located within range of Mokmer Drome and most of them could also fire on Borokoe Drome. The key to Colonel Kuzume's defenses in this area was the West Caves area, located about 50 yards north of the low ridge and about 1200 yards north of the western end of Mokmer Drome. The West Caves were actually three large sumps, or depressions in the ground, which were connected by underground tunnels and caverns. The caves were ringed with pillboxes, bunkers, and foxholes, and an extensive system of coral and log emplacements was built along the spur ridge above Mokmer Drome. Biak naval headquarters was originally located in the West Caves, which could shelter 1000 men, and Colonel Kuzume planned to move Biak Detachment headquarters to the caves for the final defense of the airdromes. As long as the West Caves and the positions along the low ridge were occupied by the Japanese, Allied planes could not safely use the airfields.
Chief of Staff of 2nd Area Army, Lieutenant-General Numata Takazo and Rear-Admiral Senda Sadatoshi, Commander of the 28th Special Base Force, with HQ at Manokwari had come to visit the garrison just as the Allies were preparing to invade, with Numata choosing to stay on the island to direct the battle alongside the resourceful Kuzume. Yet all of the Japanese at Biak were about to be caught with their pants down as many of their troops were scattered about the island. The Biak Detachment would not be in their defensive positions on Z Day but were apparently being held mobile. Detachment headquarters, the 1st Battalion of the 222nd Infantry about half of the 19th Naval Guard Unit, and miscellaneous service organizations were all located in a cave and garden area on the inland plateau about 3,000 yards north-northwest of Bosnek. Outposts at Saba and Opiaref were held by the 1st Company, 222nd Infantry, and a platoon of the 2nd Company was stationed along the main ridge behind Bosnek. The bulk of the 2nd Battalion, the rest of the naval guard unit, and some naval antiaircraft organizations were located at the East Caves. Naval headquarters, various naval service units, and the 6th Company, 222nd Infantry, were at the West Caves. Most of the army service units were at Mokmer Drome or disposed along the low ridge north of that field. The bulk of the 3rd Battalion was posted at the west end of the same airfield. One platoon of the 10th Company was at Sorido, guarding the southern terminus of a trail which led north across the island to Korim Bay. The tanks had not yet moved to Saba but were assembled on the terrace north of the eastern end of Mokmer Drome.
On the morning of May 27, Fechteler carried out his naval fire support as planned and General Kenney’s bombers also launched their air bombardment, receiving little answering fire from the surprised Japanese shore installations. Yet there was a westerly current off Biak that would push the transports over 3000 yards to the west, which would complicate the landings. A rocket-equipped LCI, which began firing on the beaches about H minus 4 minutes, led the first LVT wave toward the shore. The LCI fire, consisting of rockets and fire from automatic weapons, continued until H plus 2 minutes, when it was lifted because it began to endanger the troops who were unloading and pushing inland. The first waves of LVTs then formed rapidly and crossed the line of departure; but because of the westerly current and the smoke and dust raised by the preliminary bombardment, they would end up landing on a mangrove swamp almost 3000 yards west of Green Beach 4. Nevertheless, by 7:30, the 2nd Battalion, 186th Regiment had successfully landed and was pushing beyond the swamps to the main coastal road connecting Bosnek and the airfields. Five minutes later, Companies I and K of Colonel Newman’s 186th Regiment also landed about 700 yards east of the 2nd Battalion. Realizing about the westerly current, Fechteler then started to turn succeeding waves eastward to the proper beaches, with the troops coming ashore in disorder for the next thirty minutes.
With more than half of his regiment already far west of the proper landing beaches, and knowing that the landing had become disorganized and that the rest of the boat waves were being delayed, Colonel Newman asked the task force commander if the 186th Regiment should continue with its original mission or whether it might be feasible to switch missions with the 162nd Regiment and start moving west toward the airfields. General Fuller, the Task Force commander, ordered the 186th Regiment to continue with its original mission. As events turned out, it might have been better had the regiment continued west, and it is possible that a great deal of time might have been saved if the missions had been switched. In the first place, the maps with which the task force was supplied were so inaccurate that both regiments soon came upon terrain features that threw much planning out of gear. Secondly, most of the 186th Regiment had landed so far west that both it and the 162nd consumed much valuable time getting to their proper locations. Finally, an exchange of missions might have been executed without much difficulty, for, in amphibious training, the 41st Division had learned to switch missions when such mistakes were made.
Luckily, the landings would face no opposition, though the confusion would give Kuzume time to prepare his defense. By 8:00, the rest of Newman’s 3rd Battalion had landed to secure the jetties; and by 10:30, Companies I and K arrived to take their position west of Old Jetty. Entangled with the landed artillery and tanks, the 2nd Battalion would only be able to reach the area east of New Jetty by noon, then sending patrols to the north and east to secure the Bosnek perimeter. The face of the coral ridge behind Bosnek was found to be rough and honeycombed with small caves. Companies F and G, aided by elements of the Support Battery, 542nd Engineer Boat and Shore Regiment, sent patrols along the steep slope and to the top of the ridge to investigate many of the caves, most of which proved to be unoccupied, though three Japanese were killed near caves directly north of New Jetty. The companies moved over the first slope to a second ridge line which was parallel to and about seventy-five yards north of the first. Company G started looking for a trail which was thought to lead over the ridges to the plateau north of Bosnek, but it was Company E which, shortly after noon, found the ill-defined track. A few Japanese from the 2nd Company, 222nd Regiment in a pillbox temporarily prevented the two companies from securing the trail, which was not cleared until 2:00 hours, after the pillbox had been destroyed. During the late afternoon, patrols were sent north of the ridges to the area which the Japanese had surveyed for an airdrome. A few Japanese , most of whom fled upon being sighted, were found at the airdrome site, but there were no signs of large organized enemy groups north, northeast, or east of Bosnek insofar as the 186th Infantry could ascertain.
The only enemy action during this day would be an air attack by four Japanese bombers. A few enemy planes which flew over Biak around noon fled before anti-aircraft guns from ship or shore could be brought to bear. But all anti-aircraft crews were on the alert to expect further Japanese air action late in the afternoon. Because of the difference in time of sunset at the closest Allied and Japanese bases, Japanese aircraft could remain in the Biak area about half an hour after Allied planes had to leave. The expected attacks developed shortly after 4:00, when four Japanese two-engined bombers, accompanied by three or four fighters, approached the beachhead from the north, flying low over the ridge behind Bosnek and thus escaping radar detection. Some excellent targets were ready for the Japanese. Admiral Fechteler had permitted four LST's to tie up side by side at one of the jetties. Although he knew this move to be tactically unsound, he considered it justified because of the importance of the cargo aboard the LST's and because the jetty provided the only good spot for LST beaching. The Japanese bombing was accurate, but the LST's were lucky. None of the Japanese bombs exploded! Though the Japanese planes also bombed and strafed the beaches, none of the bombs dropped ashore exploded, while the strafing runs killed only one man and wounded two others. All four bombers were shot down by ground or ship-based antiaircraft, and the Japanese fighters were driven off by some Allied fighter planes which had remained late in the area. One Japanese bomber crashed into the water, sideswiping an SC which was standing offshore. Two of the ship's crew were killed and nine wounded. The SC had to be towed away for repairs, and a few other naval vessels suffered minor damage from strafing. There was negligible damage to supplies and equipment ashore. Total Allied losses as a result of the air raid were three killed and fourteen wounded, most of them naval personnel. Unloading also progressed satisfactorily, with 12000 men, 12 medium tanks, 29 artillery pieces, about 500 vehicles, and an estimated 3000 tons of bulk cargo being landed by 5:15.
Meanwhile, Colonel Haney’s 162nd Regiment had begun landing shortly after 9:00 and immediately started moving west along the main coastal road towards Biak’s three airdromes. Moving with speed, the 3rd Battalion passed through Ibdi village at 10:30 and then began to traverse the difficult Parai Defile. At 11:15, the regimental Intelligence and Reconnaissance Platoon discovered an enemy position on the face of the cliff west of Ibdi, that the 162nd Infantry first learned of the existence of the Parai Defile. At 1:00 the 3rd Battalion, with six tanks of the 603rd Tank Company leading the advance, arrived at the eastern entrance to the defile. There was no large Japanese force stationed along the cliff, but the few Japanese had such a tactical advantage over troops moving along the coastal road that they were able to delay the 162nd Infantry's advance for some time. Meanwhile Company E, which had been attempting to advance along the ridge north of the rest of the regiment, had found that the terrain and thick vegetation made progress along that route next to impossible. Since the company was lagging far behind the rest of the advance and since strong enemy opposition had not yet been encountered either inland or on the coastal route, it withdrew to join the rest of the 2nd Battalion on the beach, and by the time that battalion had reached Parai, Company E was back in place.
By 3:00, the 3rd Battalion had successfully pushed through the defile and had secured Parai and a large jetty at that village. Progress west of the Parai Defile was without noteworthy incident during the rest of the afternoon, so Haney’s 2nd and 3rd Battalion would be able to dig in at Parai by nightfall. On the other side, Kuzume was surprised by the landings, but he was expecting the enemy to land exactly there, where the extreme narrowness of the beach and the few entrances inland would make deployment difficult. Deciding to seize this momentary advantage, he thus ordered his 1st and 3rd Battalions to carry out an attack all along the Bosnek beachhead during the night. On the 3rd Battalion front, after an unsuccessful raid against two batteries near Ibdi. Then the 3rd Battalion, 222nd Infantry , renewed the attack with grenades and rifle fire, some circling to the north around Battery C and a few others moving against Battery B, located 200 yards to the east. Attacks on Battery C continued until daylight, when the last Japanese withdrew. The action cost Battery C 4 men killed and 8 wounded, while a near-by antiaircraft detachment lost 1 man killed and 1 wounded. Over 15 of the enemy had been killed during the night and an unknown number wounded. The 1st Battalion also raided the beachhead, suffering many casualties as a result.
On the morning of May 28th, the 162nd then resumed its westward advance, with its 3rd Battalion rapidly proceeding through Mokmer village without opposition. By 9:30, however, the Americans began to face stiff resistance at a road junction nearly 1500 yards west of Mokmer. Supported by artillery, Company K would be able to push to within 200 yards of Mokmer Drome; yet Kuzume would rapidly counterattack them with his 2nd Battalion. Charging repeatedly, the Japanese would eventually force the Americans to pull back by noon, with Lieutenant Yokoyama Hideo dying heroically during these attacks. Emboldened by this success, Kuzume then launched an all out assault from the East Caves area.
On the main ridge north of Mokmer the Japanese had another strongpoint east of the West Caves, which was called by the Japanese the East Caves. Behind Mokmer the ridge rose to a height of 240 feet. It was not so steep a cliff as the Parai Defile barricade, but it could not be climbed without the use of hands. About three quarters of the way to the top was a flat ledge from which two large caverns, similar to those in the West Caves area, could be entered. The Japanese constructed pillboxes on the ridge both below and above the ledge, and in the caverns they emplaced mortars, 20-mm. guns, and heavy machine guns. Observation posts were also set up at the East Caves, from which an unobstructed view of the coast from Parai to the west end of Mokmer Drome could be obtained. The Biak Detachment used the East Caves principally as living quarters, supply dumps, and as a connecting link between the Ibdi Pocket and the West Caves. Continued Japanese occupation of the East Caves would endanger Allied troop and supply movements along the coastal road from Parai to Mokmer Drome. The enemy threw more troops into the battle from the East Caves area until the attackers were coming not only from the west but also from the northwest and north. The Japanese split the 3rd Battalion by driving a wedge along the cliff between the troops on the shore and those on the terrace. Companies L and M were cut off. The 2nd Battalion, attempting to get on the terrace to the north of the 3rd Battalion, was pinned down by Japanese fire from the East Caves and was unable to advance. Company G, on the terrace north of the main road and between the 2nd and 3rd Battalions, was also cut off.
In response to the attacks, Haney ordered the 1st Battalion to move north from Parai onto the main coastal ridge to outflank the enemy positions, but efforts to do so were halted by enemy fire from the East Caves. Two companies patrolled in the broken terrain along the main ridge but were unable to move westward. Most of Company L and the Company M detachment which was also on the coral terrace managed to find a covered route back to the rest of the 3rd Battalion on the shore, but one platoon, initially surrounded, had to fight its way eastward into the lines of the 2nd Battalion, north of Mokmer village. Company G, on the terrace north of the main road and between the 2nd and 3rd Battalions, was also cut off and withdrew to the 2nd Battalion only with difficulty, and after it had suffered many casualties from Japanese fire. During the afternoon the 3rd Battalion stood off two more concerted enemy counterattacks, one at 12:00 and another shortly after 2:00, and suffered more casualties from the enemy mortar and artillery fire. During the latter attack, the Japanese began moving some light tanks forward from the Mokmer Drome area. The 3rd Platoon, 603rd Tank Company, engaged these tanks at a range of 1,200 yards and, with the aid of fire from destroyers lying offshore, drove the enemy tanks back into defilade positions. Three tanks of the 603rd were damaged by Japanese artillery fire and three men of the same organization were wounded during the action. Meanwhile, General Fuller had decided to reinforce the 3rd Battalion, 162nd Infantry. The 1st Platoon, 603rd Tank Company, moved west along the coastal road. At the same time small boats manned by the 542nd Engineer Boat and Shore Regiment were also sent forward with ammunition and medical supplies, both dangerously low. The small craft moved along the shore out of range of Japanese mortar and artillery fire until opposite the 3rd Battalion's position and then shot inshore at full speed, one by one. Supplies were replenished and the worst casualties evacuated despite continued shelling of the 3rd Battalion's position by the Japanese. The 1st and 2nd Battalions continued their efforts to clear the Japanese from the terrace behind the 3rd but met with little success.
By late afternoon, just as the 3rd Battalion's position was becoming untenable, Fuller gave up plans for further attempts at reinforcement and ordered Haney to withdraw his 3rd Battalion. The withdrawal started slowly because communications difficulties still prevented concentration of supporting fires. However, at 5:00 the regimental commander finally ordered the 3rd Battalion to start moving back along the coastal road. Tanks were to act as point, and rear guard and close-in artillery fire was substituted for a disengaging force. The battalion was to continue eastward until it had passed through the 2nd, which was setting up a new defensive position east of Mokmer village. The men of the 3rd Battalion moved in small parties along the beach and main road, which was intermittently swept by Japanese mortar, machine gun, and rifle fire. Many troops were unable to use the main road, but had to drop down to the beach below the overhanging cliff. Four tanks brought up the rear and protected the north flank. Between 1830 and 1900 all elements of the 3rd Battalion reached safety beyond the 2nd Battalion's lines and began digging in for the night east of the latter unit. Casualties for the day, almost all of them suffered by the 3rd Battalion, were 16 killed and 87 wounded.
Facing strong resistance, he also decided to commit his tank company to the attack. At around 8:00, new waves of Japanese infantry, now supported by four tanks, appeared west and north of the 2nd Battalion, thus beginning the first tank battle of the war in the Southwest Pacific Area. The 2nd Battalion, 162nd Infantry, with the 1st Platoon, 603rd Tank Company, in support, was astride the main coastal road 1,000 yards east of Mokmer. The battalion's left flank was on the beach while its right was against the coastal cliff and less than forty yards inland. Between the beach and the cliff was a coconut grove. The main coastal road crossed the rise of the cliff at a point about 475 yards west of the 2nd Battalion's lines. Shortly after 8:00 the Japanese tanks, followed by an infantry column, advanced down the incline where the main road crossed the cliff and deployed in echelon left formation in the coconut grove. The Japanese vehicles were light tanks, Type 95, weighing about nine tons, carrying a crew of three men, and armed with one 37-mm. cannon and two 7.7-mm. machine guns. They were opposed by two General Sherman M4A1 medium tanks, the heaviest armament on which was the 75-mm.
Each Japanese tank was stopped by one round of 75-mm. armor-piercing ammunition, while the enemy infantry was literally mowed down by the machine guns and mortars of the 2nd Battalion, 162nd Infantry. Armor-piercing 75-mm. shells passed right through the Japanese light tanks, and the Shermans followed with a few rounds of 75-mm. high explosive, which tore holes in the Japanese vehicles and blew loose their turrets. During this action several hits scored on the Shermans by the Japanese 37-mm. guns caused no damage. About thirty minutes after the first attack the Japanese sent in a second wave of three tanks, which used the same route of approach and the same formation in the coconut grove. These three were quickly destroyed by three Shermans. One enemy 37-mm. shell locked the 75-mm. gun of one Sherman in place, but the American tank backed part way into a shell hole to obtain elevation for its weapon and, despite the damage, managed to destroy one of the enemy tanks. The Japanese tanks having been stopped and the leading elements of the second infantry wave killed, the attack disintegrated and the enemy withdrew. For an hour or so the Japanese were quiet, but late in the morning, under the cover of machine gun fire and mortar barrages, they began to circle north of the 2nd and 3rd Battalions, 162nd Infantry. New infantry attacks began about 12:00. The enemy was unable to dislodge the 162nd Infantry, but his mortar fire caused many casualties within the regimental perimeter and the Japanese managed to cut the coast road east of a large T-jetty at Parai. Company B and the Cannon Company counterattacked the Japanese roadblock behind close-in mortar support and succeeded in dislodging the enemy by fire and movement.
During the afternoon of May 29, the 162nd thus moved back to Parai, where the 2nd Battalion and two companies boarded some amphibious craft back to Bosnek while the rest of the regiment moved overland through the Parai Defile and took up positions at Ibdi The 162nd Infantry's casualties during the day were 16 killed, 96 wounded, and 3 injured. The regiment estimated that it had killed over 500 Japanese during the day. Though Kuzume’s forces had suffered massive casualties, they had heroically managed to stop the enemy advance and would subsequently push troops forward to Parai and into the cliffs along the Parai Defile. They would however also lose most of their armor during these attacks. Only five tanks survived and were withdrawn to the West Caves.
Pending the arrival of reinforcements, General Fuller planned to use his available troops to hold the west flank at Ibdi and expand the beachhead at Bosnek. The 162nd Infantry was to establish a semicircular perimeter beginning on the beach west of Ibdi, reaching north to the main ridge, and returning to the beach at the village. The 1st Battalion, 186th Infantry, would maintain a perimeter around Mandom, where the Hurrican Task Force HQ was located, while the 3rd Battalion moved over the ridge behind Bosnek to set up defenses on the inland plateau. The 2nd Battalion, with part of the 3rd attached, would remain at the Bosnek beachhead. During this period, the 800 well-armed men of the 3rd Battalion, 222nd Infantry in the Ibdi Pocket, made only harassing attacks with small groups against the positions of the 162nd Infantry. On 30th and 31st of May the 162nd Infantry patrolled around the main ridge near Ibdi for a route over which large bodies of troops might move north to the inland plateau in preparation for the second attack westward. During the course of this patrolling, it was discovered that the main ridge from Bosnek to the Parai Defile actually comprised a series of seven sharp coral ridges, the crests of which were 50-75 yards apart and separated by gullies 50-100 feet deep. These separate ridges were honeycombed with small natural caves, potholes, and crevices. There was little soil on most of the coral, yet the area maintained a cover of dense rain forest containing trees 8-20 inches thick and 100-150 feet high. The 162nd Infantry discovered two native trails over the ridges. The most easterly of these, designated "Old Man's Trail," began on the beach road about 1,200 yards west of Mandom. It was a fairly well defined track which swung north over the seven ridges along a comparatively easy route. Another track began 1,200 yards to the west, near Ibdi. Called "Young Man's Trail," the latter followed a very difficult route over the ridges to the inland plateau. Both of these trails ran through the outer defenses of the Ibdi Pocket, into which the Biak Detachment, on 30 May, moved the 3rd Battalion, 222nd Infantry. On 30 and 31 May the 162nd Infantry's patrols along the ridges north of Ibdi and Mandom were harassed by the Japanese in the Ibdi Pocket, which had not yet been recognized as a major enemy strong point. On 30 May the 162nd Infantry located a water hole near the beach terminal of Old Man's Trail. A regimental water point established there was constantly harassed by Japanese rifle fire from the Ibdi Pocket area or by small enemy parties which moved down out of the ridges north of Ibdi and Mandom. The Cannon Company, 162nd Infantry, was therefore assigned the missions of clearing the enemy from the water point area and protecting that important installation from Japanese attacks. Halfway through the Parai Defile, a little over a mile west of the 162nd Infantry's main perimeter, an underground stream ran from the base of the cliff into Soanggarai Bay. At the point where the main road crossed the stream, the 162nd Infantry set up an ambush to prevent Japanese infiltration from the west along the beach. The ambush site was also used as a patrol base from which small parties reconnoitered along the cliffs of the Parai Defile to discover enemy dispositions in the area. Patrolling on 30th and 31st of May cost the 162nd Infantry 6 men killed, 17 wounded, and 4 injured.
On the main coastal ridge between the village of Ibdi and the Parai Defile the Biak Detachment developed another center of resistance which came to be known as the Ibdi Pocket. The terrain in the area was a series of knifelike east-west ridges separated by depressions and crevices up to fifty feet deep. These ridges were connected in places by cross-ridges, and the entire area was covered with thick rain forest and dense jungle undergrowth which had found a foothold in the coral. Pillboxes of coral and logs, hasty emplacements of the same materials, small caves and crevices, and foxholes at the bases of large trees were all utilized by the enemy to defend the area.
Back to the Wakde-Sarmi area, General Patrick was preparing to launch another assault on Lone Tree Hill. On the morning of May 27th at 7:00 two destroyers, firing on Lone Tree Hill and the Maffin Strip area, started scheduled fire support for the day's advance. Artillery and infantry action on this morning was much more closely coordinated than on the previous day. The destroyer fire lasted until 7:45, at which time the field artillery and all the 81-mm. mortars of the 158th Infantry laid concentrations on suspected and known enemy positions in the defile, on Lone Tree Hill, and on Hill 225. After this Colonel Herndon sent his 1st Battalion against the defile between Lone Tree Hill and the eastern nose of Mount Saksin and his 2nd Battalion against Hill 225. At 8:30 Company F, moving around Company E on the south flank, started its attack. Behind close artillery support, apparently controlled by artillery liaison planes for the most part, Company F pushed up a terrain feature initially believed to be Hill 225. It was not discovered until late the next day that F Company was actually on the eastern nose of Mt. Saksin and about 700 yards east of its reported location. Since artillery fire had knocked out two enemy machine gun nests which had been delaying the advance, patrols of Company F were able to reach the top of the eastern ridge. The rest of the company moved up the hill at 10:00; encountering scattered rifle fire from enemy positions to the southwest. Company E, just before noon, arrived atop the same hill on F's right. Company E had orders to secure the southern slopes of the defile between Hill 225 and Lone Tree Hill. Company B, still at the eastern entrance to the defile, was again unable to make any progress and during the morning was held up by machine gun and mortar fire from concealed enemy positions on the southern and southwestern slopes of Lone Tree Hill. No sooner had some of these positions been eliminated by American artillery and mortar fire than Company B was subjected to enemy machine gun and mortar fire originating from the northeast side of Hill 225, the reported location of Companies E and F. Actually, the artillery fire had not been entirely effective, because it had not reached into deep draws or caves in which many of the Japanese weapons were emplaced. Company E, attempting to move down the northern slopes of the eastern ridge to Company B's aid, was soon forced back by enemy rifle fire and infantry counterattacks from the west. At the same time small parties of Japanese, under cover of their own machine guns, started a series of minor counterattacks against Company B. Company F did not become engaged in this action. Instead, the company dug in on the ridge it was holding and sent patrols to the south and west to probe Japanese defenses. It was soon discovered that the combination of rugged terrain and Japanese machine gun and rifle fire limited patrolling to a very small area. North of Company B, Company A patrolled along the west bank of the Snaky River and on the eastern slope of Lone Tree Hill during the morning and early afternoon. About 4:30 the company moved in force up Lone Tree, finding the eastern slope of the hill to be unoccupied. Most of the fire that had harassed the company during the morning had apparently originated on the beach below the northern face of Lone Tree Hill. For the night the unit dug in at the crest of the hill. Again, little ground had been gained, although the eastern nose of Mr. Saksin and Lone Tree Hill had been at least partially occupied. At the same time, Patrick was informed that two battalions of the 163rd Regiment would be shipped to Biak to reinforce Fuller on June 1st, with General Krueger also preparing the 6th Division led by Major General Franklin Silbert to be dispatched to Wakde to replace the 163rd. Yet before this could occur, Colonel Matsuyama crossed the Tementoe River and launched a surprise night attack against Toem.
During pitch-black night at 8:30, an estimated 100 Japs struck 1st Battalion's area. Divided into small groups, but in two major commands, they carried grappling hooks, knives, grenades, knee-mortars, and rifles. Their grappling hooks had two prongs, like anchors and were attached to long ropes by which they could pull to explode booby traps harmlessly. A knee mortar barrage began the attack. While their mortars drove the men to ground, their grappling hooks caught booby trap wires and exploded attached grenades. They struck from southeast and southwest, two different commands about 150 yards apart. First command shouted wildly and threw grenades. They fired a light machine gun down A Company's street and holed up their tents. But this command's howling rush with grenades was just a feint to cause confusion. The second command, around 35-40, made the main drive. Easily they broke through 1st Battalion's far-spread perimeter holes. An estimated 25 made the serious penetration. They were trying to reach the Regimental command post to kill the top officers. Some of the staff officers were actually cut off outside their holes in a tent and actually unarmed. Ten Japanese almost reached the command post before they were cut down. Such was the official report, but 163rd men said that they tried to blow up the motor poo, nearly 100 of them. From a slit trench, four blazing M-1s stopped them, from the motor pool chief Staff Sergeant Burton, Staff Sergeant Engbretson, T/4 Switzer, and T/5 Donakowski. They piled up 13 dead Japanese, the last just 20 feet away. On a whistle signal, all Matsuyama's men withdrew.
The wild attack prompted Patrick to not to ship the 163rd towards Biak. The following morning, after another well-timed preliminary artillery bombardment, Herndon once again threw his forces against the Ilier Mountains, yet the result was the same as before. Nonetheless, his troops would be able to cover the amphibious arrival of two tanks to aid in further attacks; but with the situation soon becoming untenable because of strong Japanese counterattacks, all his companies ultimately had to withdraw to the Snaky River line. On May 29th, Krueger finally notified Patrick that the two battalions of the 163rd would have to leave for Biak the next day, so this would force Patrick to cease offensive action and withdraw the 1st Battalion, 158th Regiment back to Arare. Yet further Japanese counterattacks also forced Herndon to withdraw his remaining forces to the Maffin area as well, where he would form a new defensive line.
Patrick ultimately disagreed with Herndon’s decision to retreat, judging the withdrawal to be unwarranted and would relieve Herndon of his command, replacing him with Colonel Earle Sandlin. Colonel Herndon's fears of attack along his line of communications had been well taken, for the Right Sector Force had begun flanking movements designed to recapture the entire Maffin Bay area. However, the combat engineers quickly proved their versatility by driving off the enemy force with rifle, carbine, and machine gun fire. Five of the engineers were killed. Enemy casualties could not be estimated since the Japanese removed their dead and wounded during the night. The remainder of the night was more quiet, and the next morning the defenses along the Tirfoam were improved. There were a couple of minor attacks during the afternoon and desultory rifle and 70-mm. or 75-mm. artillery fire was directed against all American units still west of the Tor. The 147th Field Artillery Battalion, withdrawing to the east bank of the Tor late in the afternoon, was struck by some of this enemy artillery fire and lost one man killed.
A new defensive line along the Tirfoam was being developed on May 30th as the bulk of the 163rd Regiment would depart for Biak. This left Patrick’s forces spread out over almost twelve miles of coastline, just as Colonel Yoshino was about to launch his night attack. After the difficult river crossing, the 223rd Regiment had spent three days moving into the jungle southwest of Arara, from where they launched a series of simultaneous attacks against some anti-aircraft positions along the beach.
A 6:05 on June 30th, a guard at B Battery's Position No 6 challenged two men in the jungle across the beach road. Other Japanese were moving west down the road. When they did not answer his challenge, he fired, and hit the ground. Instantly, Japanese machine guns, rifles, mortars, and even grenades hit the B-6 position. The anti-aircraft men killed 10 Japs, but one heavy machine gun jammed. The second gun became overheated and had to cease fire. The Japanese were hard to hit in the dark. They were heavily camouflaged with leaves and nets down to their hips. After one American was killed, the anti-aircraft men left their emplacement and fled 500 yards east on the beach road to Battery A's Position 7. Joined with the men of A-7 - they had already stopped one attack - the B-6 men helped fight about 15-25 Japanese. From 6:40 to 4:30 next day, the Japanese struck intermittently, but rifle and machine guns fire repelled them. About 500 yards west of the B-6 position where the first attack had occurred, Battery A-6 also endured harassment from Japanese mortar, rifle, and machine gun fire. At least twice, the gunners repulsed attacks. A fourth position, Battery B-8, which was 400 yards west of A-6, was assailed about 6:30 also. The anti-aircraft men's .50 multiple heavy machine gun became overheated and jammed. Rifle ammo was running out. Scurrying from the gun-pit, they took cover in the shore brush until the Japanese left at 4:30. All attacks began about the same time, about 8:30, and some men glimpsed a Jap officer with his saber who was giving orders. All Japanese dead had rolls of white gauze in their mouths, and the Japanese officer had completely covered his lower face. The Americans thought that they used these means to prevent them from shouting or screaming when they were wounded. While they attacked the anti-aircraft batteries, Yoshino's men also tried to storm 1st Battalion 158 Infantry protecting Task Force Headquarters and the supply dumps. About 7:00, rifle and machine gun fire began impacting 1st Battalion positions. A captured heavy machine gun fired also. At 10:00 came a furious suicidal attack against B Company - beaten off with rifles, grenades, bayonets, pistols, and even knives. They failed to fire the supply dumps with demolition charges and Molotov cocktails. In the end, the Americans miraculously only lost 12 killed and 10 wounded while inflicting heavy casualties on the enemy. But fearing more enemy attacks, Patrick would decide to reduce the number of separate perimeters along the beach, from 21 to only 8.
The bulk of the 158th had to withdraw behind the Tor, leaving only its 2nd Battalion west of the river to secure the bridgehead. Facing little resistance, the Japanese recaptured Maffin, though they would be unable to push Sandlin’s troops behind the river. Yoshino and Matsuyama were unable to coordinate their efforts however, allowing the Americans to continue to strengthen their defenses for the next few days, with the Japanese only able to launch nightly raiding attacks that were easily repelled. On June 5, the first units of Major-General Franklin Sibert’s 6th Division then began to arrive, freeing up the 158th to continue with its offensive.
Sandlin then launched an attack with his 1st and 2nd Battalions supported by tanks crossing the Tor to attack Maffin on June 8, meeting increasingly strong enemy resistance from a line of hastily-repaired bunkers and pillboxes. The tanks were able to reduce the Japanese defenses due to their strong firepower, but not before the Americans had to dig in by nightfall.
The night passed without incident and early on June 9th patrols began to probe westward toward the Tirfoam. Scouts reported that the Japanese were holding another defense line, including reoccupied bunkers, on a slight rise at the west bank of the river. About 10:00, tank-infantry teams began to destroy the Japanese-held positions along the new line. While tank 75-mm fire was destroying bunkers or forcing the Japanese to seek cover, infantrymen crept forward to toss grenades into bunker gun ports or shoot down Japanese who tried to escape from the area. While these tank-infantry team operations were taking place, the rest of the two infantry battalions rested. Japanese 75-mm. fire, from a weapon emplaced on the beach between the Snaky River and Lone Tree Hill, harassed the 1st Battalion for a while, but this fire was summarily stopped when a 155-mm howitzer of the 218th Field Artillery Battalion scored a direct hit on the enemy piece. By 11:30 the enemy defensive positions had been cleaned out and the 1st and 2nd Battalions resumed the advance westward. Aided by fire from the 147th Field Artillery, which had supplanted the 167th in the close support role, the two infantry units probed cautiously forward, and it was not until 3:30 that both reached the east bank of the Tirfoam. Opposition was scattered, but the American units lost 6 men killed and 6 wounded. It was estimated that 50 of the enemy had been killed and one was captured.
At this point, the 158th would have to stop its advance because they received new orders from Krueger, who planned to employ the regiment for an assault on Noemfoor Island, 300 miles northwest of Sarmi, in late June or early July. As such, advances west of the Tirfoam would be postponed until a second combat team of the 6th Division could arrive in the area to relieve the 158th in mid-June.
General Sibert assumed command of the Tornado Task Force on June 12th. On 10 and 11th June the 158th Infantry limited its activities to patrolling, consolidating defensive positions, and driving Japanese outposts westward. One outpost, lying southeast of the 2nd Battalion, was manned by about a hundred Japanese and had to be cleared by tank fire and infantry assault. The Japanese, who were members of a 223rd Infantry company assigned to the Right Sector Force, fled toward Mr. Saksin, leaving behind 4 heavy machine guns, 1 light machine gun, 2 70-mm. howitzers, and 1 37-mm. antitank gun. On 14 June the 20th Infantry, 6th Division, relieved the 158th Infantry at the Tirfoam. The 158th recrossed the Tor and went into a defensive perimeter on the west bank of Tementoe Creek. Patrols sent south and east during the next week encountered a few stragglers from the Japanese garrison at Hollandia or from the Matsuyama Force. On the 22nd the entire regimental combat team was relieved of all combat responsibility in the Wakde-Sarmi area and began final preparations for the Noemfoor Island operation. During its operations in the Wakde-Sarmi area the 158th Regimental Combat Team lost 70 men killed, 257 wounded, and 4 missing. The unit took 11 Japanese prisoners and estimated that it killed 920 of the enemy. With their supply line compromised, Yoshino and Matsuyama would also decide to withdraw from their present positions about this time, which would allow the 36th Division to establish better defensive positions in the Ilier Mountains line. Yet that is all for Operation Tornado and Hurricane for now, as we now need to head over to the Imphal-Kohima front.
By June, the situation at Manipur saw General Slim’s 14th Army losing all of their advantages. Despite the extreme odds, with a slim chance of success, General Mutaguchi continued his wild attacks against Imphal. As it was, the two armies had been battling it out in difficult terrain and conditions. There were the steep and often jungle-covered hills, the heat for men not accustomed to it, the risk of tropical diseases like malaria and the leeches – not to mention the weeks and months of both physical and psychological strain from fighting a formidable enemy. The monsoon rains that began later in May only made matters worse. As the days passed by, the low-lying areas in the Imphal Valley would flood because of the downpours, while the streams and small rivers everywhere would become raging torrents. The water level of Loktak Lake would also rise, making it especially uncomfortable for the units of both sides dug in at some of the lakeside villages on the Tiddim Road. Dysentery and diarrhea became an ever-greater concern. Foot rot would start to set in for men in their flooded positions. The slopes in the hills became slippery and that much more treacherous to navigate. The incessant rains would dissolve stretches of ‘fairweather’ roads and ‘jeepable’ tracks into mud and slush everywhere, while triggering landslides in the hills. For the units on higher altitudes like the Shenam Saddle, Point 5846 and the Ukhrul area, the nights would become shockingly cold and damp, adding to their misery. Yet things were undoubtedly harder for the Japanese, who had carried few supplies and didn’t expect to be strung out fighting for so long.
To the north, General Sato’s 31st Division were withdrawing from Kohima towards Ukhrul, defying Mutaguchi’s orders, with General Miyazaki providing rearguard at Viswema, whileGeneral Grover’s 2nd Division pursued them. Miyazaki’s men held out at Visweman until June 12th, before withdrawing to Maosongsang. Then they held out at Maosongsang until June 16, before retreating to the last holding position at Maram. Over to the south, General Brigg’s 5th Division was engaging Colonel Matsumura’s 60th Regiment, fighting brutally for control over the Imphal-Kohima road. The battered Japanese defenders were fighting tooth and nail to prevent the opening of this vital supply line. The 9th and 123rd Brigades pushed on, they would only be able to capture the Zebra hill on June 7. The following day, the 3/14th Punjabis made a wide hook and arrived on the road behind Japanese lines by nightfall, where they would repel three heavy counterattacks. This would allow the 123rd to clear the hill positions near Modbung and link up with the Punjabis on June 11th. The 9th Brigade made great progress during these days, pushing on to Satarmaina by June 13th. General Gracey’s 20th Division was also attacking towards the Ukhrul Road during this period, with the 80th Brigade advancing northwards from Kameng up the Iril River Valley on a wide encircling move towards Litan while the 100th Brigade attacked up the road towards Kasom. Though the 80th faced little resistance, the 100th would struggle to progress against the fierce counterattacks of the recently-arrived 67th Regiment. By mid-June, the 51st Regiment was also ordered to abandon its positions and support the 67th on the Ukhrul Road.
Over in the southwest front, the arrival of reinforcements in the form of the 2nd Battalion, under the command of Colonel Yanagisawa Kanji at the end of May, gave General Tanaka a gleam of hope that he could launch another offensive in early June. On June 6th, four battalions under Colonel Sasahara attacked the 63rd Brigade’s hill positions, applying such great pressure, General Cowan was forced to withdraw his brigade to Bishenpur the following day. On June 7th, Tanaka ordered his recently-arrived reinforcements to clear Ningthoukhong and retake Potsangbam, yet their first coordinated attack would end in failure. The attack was almost single-handedly held by Sergeant Hanson Victor Turner of the 1st West Yorks. Defending his platoon’s position on the perimeter, Turner grabbed some grenades and charged forward, throwing them at the Japanese. He did this five times, going back to gather grenades each time and returning to the attack in the face of Japanese grenade and small-arms fire. He was killed on the sixth occasion while throwing a grenade. For his bravery, Turner was posthumously awarded the Victoria Cross. The Japanese eventually captured some ground in North Ningthoukhong, but withdrew after being struck from the air and shelled.
In the meantime, after the Japanese defeat at the Gibraltar Box, the Yamamoto Detachment would continue to harass the British-Indian positions from Nippon and Scraggy Hills in early June. On the evening of June 9, the Japanese put in their last major attack on Scraggy, starting with a heavy artillery bombardment. Artillery concentrations were directed at the Japanese and an airstrike was made on their part of Scraggy and Lynch. The Gurkhas followed up with an advance. Although some ground was recovered, the Japanese maintained their grip on Scraggy’s crest. Having suffered many casualties and feeling that the Gurkhas’ new position was sufficiently strong, General Roberts then decided to halt the counterattacks, thus leaving General Yamamoto in control of Scraggy up until the end of July. Concurrently, as a last hope to break through towards Imphal, Mutaguchi was planning to conduct a desperate offensive on Palel with some reinforcements that would fail to arrive in time. Due to these delays, he would end up sending some of Yamamoto’s exhausted troops to recover Langgol and advance to the hill northeast of Palel. The Japanese managed to get beyond Langgol and attack some positions in the foothills near Palel Airfield, but were soon rebuffed. They finally sent in a commando raid on the airfield in early July, which succeeded in blowing up eight planes.
Over in Ningthoukhong, Tanaka launched another heavy assault on June 12th. Though a salient on the other side was initially captured, a ferocious counterattack would ultimately evict them. This action was performed by units of the 48th Brigade, including reinforcements sent from Potsangbam. Rifleman Ganju Lama of the 1/7th Gurkha Rifles who earned a Victoria Cross in this action. To the west, Tanaka ordered the newly-arrived 151st Regiment of Colonel Hashimoto Kumakoro to attack the British picquets overlooking the Silchar Track. After a wave of assaults, Water Picquet would fall on June 21; yet the 32nd Brigade would respond immediately with a series of counterattacks that developed into confused fighting as positions were won and lost by both sides.
On the night of 25 June, no less than a company of Japanese began attacking Mortar Bluff, a picquet position bereft of cover and a short distance away from Water Picquet. It was held by a small garrison of some 40-odd men of the 2/5th Royal Gurkha Rifles who had replaced the 7/10th Baluchis. In pouring rain, the Japanese first bombarded the position with mortars and guns at point-blank range. For the next few hours, the infantry repeatedly attacked the surrounded and dwindling garrison. Subedar Netra Bahadur Thapa defended the besieged position almost through the night, organizing counter-attacks with whatever ammunition and grenades his unit had left. The Japanese finally overran Mortar Bluff the next morning, with Netra Bahadur Thapa fighting to his death. He was posthumously awarded the Victoria Cross.
A few hours later, a company of the same unit formed for a counterattack on Mortar Bluff. In the face of heavy fire, Naik Agan Singh Rai led his section in charging a Japanese machine-gun post and killing its crew. It then recaptured Mortar Bluff and neutralized a 37mm gun position and crew. Rai now advanced on a Japanese bunker and killed its occupants, after which his company also recovered Water Picquet. For his actions that day, Rai won the Victoria Cross, the second for the 2/5th Royal Gurkha Rifles the same day. Faced with such counter-attacks and intense artillery fire from Gun Box, the last throw of the Japanese 33rd Division around the Silchar Track ended in failure. This left Hashimoto and Tanaka empty-handed for all the losses they had suffered. Tanaka was forced to withdraw units before they were annihilated. On July 2st the 214th Infantry, with only 400 effectives remaining, completed its withdrawal to the area south of Nouyangtek and the 151st was directed to move back to Laimanai. Having been decimated by sickness and straggling en route to the front, the strength of the entire 151st Infantry Regiment was, at that time, less than 100 men.
Back in the north, Briggs’ units continued to struggle for control of the Satarmaina area. The struggle over the next week centered on the main feature east of the road, the hill named Liver. The 3/9th Jats attacked repeatedly to try to dislodge the Japanese from this feature. One such attempt was made on June 15th, when Hurribombers strafed the hill, followed by heavy artillery concentrations from 25-pdrs, 3.7in howitzers and 3in mortars. A Jat company climbed the hill, but had to withdraw some 100 meters from its objective because of heavy machine-gun fire. At the same time, the 1/17th Dogras were sent off on a wide hook left of the road and the 3/14th Punjabis were able to secure the Octopus position by June 20.
North of them, Grover’s troops would also be able to break through Maram and continue south down the road on June 20, finally meeting the Dogras two days later. Beaten, Miyazaki had nonetheless fulfilled his task and could now withdraw east towards Ukhrul. Sato's rearguard fought determinedly. Often a few men with an artillery piece, grenades and a machine-gun would take up positions on the high ground above tracks, ambushing the British advance guards before melting away to repeat the performance a few km further back or, as was often the case, remaining obstinately in their positions until they were killed. Few were free from disease and fatigue, but surrender played no part in these men's vocabulary; they fought on till overtaken by a British bullet or bayonet or, more often, by starvation and exhaustion. But the 31st Division had literally fought itself to death. Exhausted men lay in pits unable to defend themselves, suicide squads with anti-tank mines tottered towards the advancing Lee Grants and Stuarts to be mown down by accompanying infantry, or obliterated by shellfire
Although the battered 31st Division would manage to survive the Kohima disaster, General Sato would be relieved of his command as he had refused to carry Mutaguchi’s orders numerous times. As a result, Miyazaki was promoted to Lt-General and given temporary command of the division by the end of June. Meanwhile, though his men had resisted like demons, Matsumura now had no choice but to abandon the road and retreat east towards Ukhrul with what remained of his command due to this new threat to the north. On June 21, the Liver position would fall at last. Again, the Japanese positions were bombed and strafed from the air, this time by three squadrons of Hurribombers for half an hour. The 4th and 28th Field Regiments, as well as a troop of the 8th Medium Regiment, fired a concentration on Liver that covered it in dust and smoke. Three companies of the Jats now went in, and yet this attack was also held by the Japanese on and around Liver. They had had enough, however, and by the next morning were found to have withdrawn from the feature. The Jats suffered around 150 casualties that week, including 33 killed. The 15th Division would adopt new defensive positions at Ukhrul to cover the withdrawal of Miyazaki and Matsumura. The main force of the 15th Division then went into defense positions in a line extending generally from Ukhrul through Tongou, Shongphel and Aishan to the 3524 Pass in order to be in position to cover and pick up the Right Assault Unit and the Miyazaki Detachment as they withdrew to the east. In order to hold the new defense positions, all available men, including all those in the rear service units, were thrown into the line. Finally the Imphal-Kohima road was reopened. Slim knew while the battle was not yet over, it had already been won.

The landings at Biak was another allied success. The first tank battle of the war in the Southwest Pacific Area saw the American Sherman's absolutely devastate Japanese Type-95’s. Within the Burma front, General Slim had finally reopened the Imphal-Kohima road spelling doom for Mutaguchi’s failed offensive.

- 131 - Pacific War - Siege of Myitkyina, May 21-28, 1944
21 mei· The Pacific War - week by week
Last time we spoke about the battle of Wakde. Operation Tornado, the amphibious assault of Wakde island faced many logistical challenges, but not as much Japanese resistance. The landing at Arare was a large success, seeing the allies secure a beachhead before advancing inland. Through a combination of air, naval and ground attacks, the smaller Japanese force was pushed back. Likewise the islands of Liki and Niroemoar were taken with relative ease as well. Over in the Burma-India theater, the battle for Kohima was gradually seeing the Japanese fail to meet their objectives. Without ammunition or provision supplies flowing to them, the Japanese at Kohima had no hope of holding back the allies. Thus the Japanese were beginning to fall back and now were setting up a defense to stop the allies from entering central Burma. Meanwhile a siege was being erected against Myitkyina.
This episode is the Siege of Myitkyina

Last time we saw General Stilwell had managed to seize the Myitkyina airstrip. Now allied forces were gradually securing northern Burma, pushing further towards Mogaung. The Japanese 18th Division were absolutely battered and barely holding on around Kamaing. However when the American-Chinese forces seized Myitkyina’s airstrip, they had failed to quickly attack the main town, which the Japanese were reinforcing heavily. Now they were being attacked from both ends. This prompted General Stilwell to dispatch General Boatner with the task force to try and turn things around. Simultaneously, Stilwell had just received word of the Chindits abandonment of the Blackpool stronghold, outraged by this he ordered them to advance northwards to support the attack on Mogaung.
Three brigades, the 111th, 14th and the 3rd West Africans were to advance north to support Calvert’s 77th Brigade to take Mogaung. The Chindits were incredulous. Nonetheless, Lentaigne, pressed by Stilwell, sought to have his 3rd West Africans, the 14th and 111th Brigades squeeze the Japanese along the western flanks of the Mogaung valley, in which Mogaung occupied the lowest point of an inverted triangle, with the other two points being Kamaing on the top left and Myitkyina on the top right. With any luck, his three brigades could capture Kamaing, which occupied an enviable place on the Mogaung River. The 111th Brigade was to move north-east and operate in the Pahok-Sahmaw area, destroying dumps and blocking enemy movement. Thebattered men of the 111th Brigade struggled to cope with the march north, to the hills east of Lakhren and west of Mogaung. Conditions were appalling on the three-day march to Lakhren village. From there, the best approach to Mogaung would be identified. They were making for a waterlogged, mosquito-infested area north east of the Lake. This area was also alive with Japanese units. They were required to support 77th Brigade’s attack on Mogaung, by pushing from the west as Calvert’s command advanced from the south-east. However, 111th Brigade was spent after Blackpool and many men were forced to return to Lakhren village. There was also a new task for 14th Brigade – the capture of Taungni. With the casualties evacuated, 14th Brigade abandoned the Kyunsalai Pass and headed north towards Mogaung. The steamy swamps continued to take their toll within the ranks of the York and Lancaster columns. Dysentery was rife. Animals collapsed and were shot where they dropped. They reached Mokso on June 25. This much-used rallying point, consisting of four huts, was a sea of mud and detritus, decorated with black clouds of flies. Rations were being consumed rapidly in an area devoid of drop zones. Brigadier Brodie, 14th Brigade’s Commander, responded to the extreme circumstances. His men, despite their dangerously poor condition, were still expected to harass the Japanese along the railway and support 77th Brigade’s assault on Mogaung. He formed his columns into “Light Battle Groups”, free of heavy weapons and the wounded and sick, now lying together in the mud. Meanwhile, some Nigerian units were now struggling on the road to Lakhren along the reailway, as were the York and Lancaster sick – around 300 in all, 200 of whom were dangerously ill.
On May 25th, the same day the Chindits had quit Blackpool, Stilwell ordered the Morris Force to seize Waingmaw, across the river from Myitkyina. Unfortunately, the Japanese had entrenched themselves at the town and enjoyed the luxury of a natural moat after heavy rains flooded the fields on the approaches to the town. Morrisforce was not a proper brigade, having only two columns of troops, to which a third from the 111th Brigade had been added 1,500 troops in total. It had been conceived to harass the Japanese on jungle areas. Now, they were up against fortified positions. The result was a bloodbath. Morrisforce then began to rapidly deplete in strength. By July 14th, it was to consist of exactly three platoons, roughly 120 men.
On May 31st, Boatner then launched his first coordinated attack against Myitkyina seeing the 42nd regiment reach the Waingmaw ferry road. Built up twelve feet above the neighboring paddy fields, the road gave the Japanese a magnificent defensive position, which they exploited cleverly. The Chinese recoiled from this natural fortification but were able to beat off a Japanese counterattack. The 150th Regiment reached the riverbank and drew up in an arc about a sawmill in which the Japanese had a strongpoint. Meanwhile Colonel Hunter’s 2nd battalion reinforced with engineers advanced to Radhapur where they were heavily counterattacked by the 114th Regiment. The next day, the inexperienced 236th Engineer Battalion was sent against Namkwi. The motive behind the 236th's attack was to contain the Japanese in the Namkwi area and introduce the battalion to combat under relatively easy conditions. One company of the 236th did succeed in entering Namkwi but instead of promptly consolidating to meet the inevitable Japanese counterattack fell out for a break. The Japanese counterattacked and drove the unwary engineers right back out of the village. Both the engineers and the 2600 replacements of the Galahad Unit that had recently arrived lacked adequate experience fighting the Japanese and as such suffered badly when fighting against them. Colonel Hunter’s veteran Marauders, however, had suffered ample casualties and thus needed these green replacements in order to continue existing as a fighting force. Boatner tossed a last ditch effort on June 3rd, but his Chinese forces had suffered 320 casualties and their ammunition was running low. While he waited for supplies to build up, he used his green american troops to give them some experience, the Chinese meanwhile tunneled towards the Japanese still suffering heavy casualties. This allowed more Japanese troops to break through and reinforce Myitkyina, with a huge relief force of the 52rd Division soon on its way.
Meanwhile, Lieutenant-General Matsuyama Yuzo of the depleted 56th Division was facing a deadly offensive of his own on the Yunnan front. After a series of negotiations between Chiang Kai-Shek and the Americans, it had been agreed, General Wei Lihuang’s Y Force would cross the Salween River to attack the Tengchong and Longling areas. This would effectively allow the allies to link the Ledo Road with China, bypassing the heavy Japanese concentration along the Burma Road. Although the Americans had supplied the Y Force with artillery and ammunition, the Chinese had failed to bring the Y Force divisions up to strength, and many questioned their training. Regardless, General Wei planned to have elements of the 20th army group cross the Salween at several points before initiating a full assault against Tengchong once reinforcements had been ferried through. Further south, elements of the 11th Army Group would also cross the Salween to launch attacks on Pingda and Longling.
On the night of May 11th, the Chinese forces began to cross the Salween River against little Japanese resistance, since Matsuyama had decided not to defend the crossing sites, instead placing his main line of resistance along the ridge line some 10 miles west. The 198th Division was able to assemble in front of the Mamien Pass; the 36th division was successfully ferried through Mengka; the brand new 39th Division managed to secure the Hueijen bridge and the 76th and 88th Divisions were converging on Pingda for the attack. On May 12th, the 198th were making good progress against the Mamien Pass as the 36th had surrounded the Japanese outposts in the eastern end of the Tiantouzhai pass. However Colonel Kurashige Yasuyoshi had his 148th regiment launched two surprise night counterattacks. All that night, the Japanese quietly filtered down from a nearby ridge and assembled near the Chinese position. Attacking at dawn, they surprised the Chinese and almost wiped them out before aid came. When darkness came, the 36th were at their bivouac. That night, the Japanese attacked vigorously, overrunning the division command post and causing the flustered 36th Division to fall back to the Salween. At dawn, the 53rd Army commander, Maj. Gen. Chou Fu-cheng, pushed a regiment across the Salween and restored the situation by attacking the Japanese flank. General Chou was an aggressive and tenacious fighter, whom his Manchurian soldiers had nicknamed Old Board-Back, and who had the reputation of never having yielded an inch to the Japanese. But even Chou could not immediately restore the morale of the 36th Division, which for some weeks took no further part in the Ta-tang-tzu fighting, and the rest of the 53rd Army had to bear the burden of clearing the pass.
In response to this, Lt General Zhou Fucheng of the 53rd Army pushed the 116th and 130th Divisions across the river to resume the advance towards Tiantouzhai. At the Mamien pass, the 592nd and 594th Regiments began clearing out the Japanese strongpoints while the 593rd Regiment moved west over mountain byways to emerge into the Shweli valley by the 16th, securing the western end of the pass and forcing Kurashige’s men to withdraw into the fortified village of Shangzhaigongfang. To the south, the New 39th would be able to secure Hemushu by the 17th. Yet the Japanese under Colonel Matsui Hideji soon recovered from the initial surprise of the Chinese offensive and the 1st battalion, 113th regiment drove the Chinese from Hung-mu-shu. The Japanese exploited their success and pushed the entire New 39th Division back against the Salween.
Further south, the 76th Division met outposts of the 1st battalion, 146th regiment and forced them back to the heights overlooking Ping-ka. Meanwhile the 88th Division from the north was fighting through a series of fortified villages as it headed south to join the 76th Division. By the 16th, thirteen villages were occupied in the area northeast of Ping-ka, but the Japanese, as they withdrew, received reinforcements. Strengthened by the 2nd battalion, 113th regiment, the Japanese did not attack the Chinese who were pursuing them, but moved south and hit the Chinese 228th Regiment south and west of Ping-ka.
Sensing the imminent danger from the north, Matsuyama redirected the 2nd and 3rd Battalions of the 113th Regiment to reinforce Shangzhaigongfang, where Kurashige would continue to resist staunchly. Reports from the American liaison teams were not cheerful. Americans observing the Kaolikung Range actions found that Japanese fire was accurate and economical, and that the enemy's use of camouflage and concealment approached perfection. The Japanese revealed no disposition to surrender though they were heavily outnumbered, often surrounded, and had neither air support nor air supply. On the other hand, the Americans reported that the Chinese endlessly wasted manpower and ammunition in costly frontal attacks. They reported that relations with the Chinese were not always as friendly as had been hoped, and they believed there would have to be better cooperation between Chinese and Americans if the Japanese were to be defeated. The Chinese were described as merely tolerating the Americans' presence and as paying little attention to their advice. The liaison personnel freely admitted their own shortcomings, and by their reports suggested that patience was the most important quality for a liaison officer to cultivate when dealing with the Chinese.
Matsuyama ha spread his forces widely, over a near 60 mile sector, thus he would be unable to perform mobile operations and was gradually shifting to a defense of the Kaolikung mountain range by the 20th. This allowed the 53rd Army to continue their advance and the New 39th to retake Hemushu. By late May, with the 198th Division apparently contained on the north, Kurashige then rushed with the 113th Regiment to reinforce the Tiantouzhai front, where they successfully stopped the 53rd Army on its tracks. Yet on June 1st, the 54th Army, emerged in the Shweli valley from Ta-tang-tzu pass to join the 593rd Regiment from the Ma-mien pass. Next day the Chinese occupied Chieh-tou village and began patrolling the Shweli valley. They took the advice of Y Force officers and donned Burmese clothes. So disguised, they found it easy to enter Japanese-held villages. When taken by surprise, the Japanese were willing to abandon many of their outer defenses. With TNT charges dropped by the 27th Troop Carrier's C-47's when the weather cleared, the 198th Division also blew up the last pillboxes at Chai-kung-tang on June 13th. When the last shots had been fired and the Chinese farmer boys of the 54th Army reported the area secure, there was bewilderment at finding only 75 Japanese bodies in defenses that must have been manned by at least 300 men, and shock and nausea when the Japanese kitchens revealed how the defenders had been able to prolong their stay. Pitiful and ghastly evidence showed that the Japanese had resorted to cannibalism when their rations failed. On June 14th the Japanese further quit Chiao-tou-chieh, leaving many stores to the 2nd Reserve and 36th Divisions. In the end, the Kurashige Detachment would pull back to Watien while the Inose Battalion retreated towards Kutungchieh.
General Wei then ordered the 71st Army to cross the Salween, just below the Huitung Bridge to attack Longling while a containing force attacked the strong Japanese harrison at Lameng. 20,000 troops of the 71st would cross the river by June 5th. At this time the 76th division left a regiment to besiege Pinga while the bulk pushed on to attack Matsuyama’s HQ at Mangshi, while the 9th Division crossed the Salween, cutting off Pingda’s line of communication. On June 4th, the new 28th Division attacked Lameng and forced Major Kanemitsu Keijirous garrison to retreat into the Mount Song fortress where they would hold out for several months. While the New 28th held down Kanemitsu, the 87th Division continued towards Longling, joining up with the 88th on June 8th to begin a siege of the main Japanese position on the Yunnan front. The Japanese still held onto the Burma Road east of Lung-ling, but as of June 7th the 87th Division had covered about two thirds of the distance along the Burma Road from the river to Lung-ling. The Chinese had to deal with small Japanese tanks, which had some moral effect but failed to halt the Chinese advance. Indeed, the latter had been fairly swift, for the Chinese had surprised the Japanese, and had been able to ease their supply problems by the capture of some Japanese rice depots.
To meet the new crisis, Matsuyama dispatched the 1st battalion, 119th regiment to stop the 2nd army at Xiangdaxiang and then attack Longling from the south. Matsuyama ordered Colonel Matsui Hideji to immediately relieve Longling from the north; and for the Yamazaki Composite Group to keep the Mangshi-Longling road open. Meanwhile, Lieutenant-General Song Xilian, had been making some progress against Longling’s two outer heights, the stout defenders would manage to repel the uncoordinated Chinese assaults for about a week. Four days of un-coordinated infantry attacks, with little artillery support, failed to carry the three mountains inside Lung-ling, and there was nothing to show for the heavy drain on the 71st Army's ammunition stocks. This gave more time for Matsuyama’s reinforcements to arrive by June 14th. On the 15th Matsui launched a heavy attack, in coordination with the besieged defenders, successfully defeating the 71st Army and consequently driving the Chinese from the vicinity of Longling. The Japanese had thus been able to drive back 10000 Chinese effectives by an attack with only 1500.
Repeated attempts by American liaison personnel with the 71st Army to learn how a small Japanese garrison could drive back a Chinese army group only brought embarrassed smiles from Chinese officers. The Chinese finally related on June 25th that the 261st Regiment had bolted, and that the commanding general of the 87th Division had attempted suicide. When fuller details of the fighting around Longling were available, anger and annoyance spread from Y Force to the Generalissimo himself. Y Force personnel considered the Chinese decision to withdraw from Longling inexcusable because the 11th Army Group had sent forward no reinforcements to meet the initial Japanese counterattacks. Of 21 battalions in the Longling vicinity on June 14th, only 9 took part in the fighting. In describing the defensive attitude of the 259th Regiment, as an example of the conduct that had cost the chance of a speedy breakthrough into Burma, one American liaison officer wrote: "From the time that we crossed the river until we reached Longling, the regimental commander continually had his troops in the rear digging emplacements and trenches in the fear that they would have to retreat." Yet that is it for the Yunnan battle for now as we need to head over to the Kamaing area.
General Tanaka’s 18th Division were withdrawing with the 22nd and 38th division in hot pursuit. To the south the Seton Roadblock was being held by 112th Regiment, threatening to thwart Tanaka’s plans. Coming to their aid, General Sun sent his 113th and 114th Regiments to descend upon Lawa, where General Aida began an unauthorized retreat on June 4th. The abandonment of Lawa severely affected the defense of Kamaing, thus General Aida was relieved of command and replaced with Colonel Imaoka Soshiro. Colonel Shoshiro immediately began to dig in at Lagawng. Meanwhile the bulk of the 55th and 56th regiments were holding onto the Nanyaseik area as General Liao’s 65th regiment cut their withdrawal route off on June 1st. While the rest of the 22nd Division were applying pressure from the north, the heavily outnumbered Japanese had no choice but to quickly cut a trail southeast, finally withdrawing on june 7th. Their retreat was chaotic, both regiments lost contact with each other and with their subordinate units as they made separate ways towards Kamaing. It would only be the 3rd battalion, 56th regiment who would arrive at Kamaing by June 10th, most of the others would reach Lakatkawng in late june. While retreating, their artillery units were intercepted by the pursuing Chinese and the artillerymen chose to die with their guns.
While the 22nd Division and 149th Regiment thus pushed towards Kamaing, General Sun had also sent the 113th Regiment to take Zigyun and the 114th Regiment to advance southwards and support the Chindit assault on Mogaung. The Chinese were able to encircle Kamaing from the west, north and east as the 149th Regiment then moving across the fields and into Kamaing to take the settlement on June 16th, pushing Tanaka’s battle-weary troops to the hills south and west of Kamaing. Meanwhile Brigadier Calbert was able to reach the Mogaung area by the start of June. 12 miles from Mogaung, Calvert’s forward troops began to run into Japanese patrols and snipers. Despite taking losses, the 3/6th Gurkhas led by Colonel Claude Rome, who in his previous incarnation had been overlord of “Broadway,” pushed on, seizing the western heights overlooking Mogaung on May 31. On June 1st, Calvert’s South Staffords linked up with Rome and the Gurkhas at the village of Loihinche. Other elements of the brigade reached the southern foothills of the heights, three miles south of the town, on June 2 and went straight into the fray. That same day, the Lancashire Fusiliers and the South Staffords also attacked Lakum (held by some ordnance troops and a field hospital). The leading force of Fusiliers was soon pinned down by heavy fire, the impasse only broken when a Bren gunner in the leading rifle section went wild, and ran “straight up the hill, firing from the hip and screaming curses at the Japanese.” Softening up the Japanese with airstrikes from Air Commando Mustangs, troops of the 1st Lancashire Fusiliers and 1st South Staffordshires attacked and wrested Lakum village away from Japanese and occupied the summit of the range of hills overlooking the city, to the northwest.
Calvert decided he would need to build a base akin to White City, where he could collect supplies and build an airstrip to take out the wounded. Calvert fixed his eye on the village of Lakum, occupying a strategic spot on the eastern foothills of the heights overlooking the Mogaung plain. Upon capturing the village, the Chindits would also find substantial ammunition, a field hospital and buildings which had obviously hosted several Japanese headquarters. The country leading up to Lakum, however, was hard stuff. It was in the midst of thick jungle intersected by deep ravines. The path proved difficult to follow as it sometimes wound along a ridge and sometimes went straight up or straight down. The place was a defender’s paradise. “A handful of resolute men could hold successive hill-tops for hours against a large force such as ours overburdened with mules and heavy stores,”.
In response to the new threat, Colonel Okada Hakuji rushed over with some units of his 128th Regiment to protect Mogaung, leaving his 1st Battalion to face the rapidly-approaching 114th Regiment and immediately recalling his 3rd Battalion from Seton. Alongside this General Honda ordered General Takeda to turn back from Myitkyina and instead secure the Moguang-Kameing area. Thus the chance to lift the siege of Myitkyina was lost. By June 3rd, the Chindits had built a new airstrip near the Tapaw Ferry, allowing airdrops of supplies and equipment to spill in. Calvert was now ready to launch his attack.
Early on June 8th, the 1st South Staffords set off to secure the Pinhmi. The village was defended by elements of 3rd battalion, 128th regiment who were also protecting some ammunition dumps in the area. The Staffords routed the Japanese and destroyed the dumps, clearing the way to the bridge. By now it was afternoon, and they stepped aside to let the 1st Lancashire Fusiliers move on to capture the 150-foot-long bridge. All seemed well until a hail of gunfire shattered the silence, tearing into the Fusiliers. Two companies were pinned down in the ditch while another was in the jungle further down. At about 6 pm, Calvert arrived at the front to confer with Major David Monteith of the attacking company. It was decided that two platoons, under the cover of a mortar barrage would dash across the bridge and secure the other bank. Calvert’s mind went to the 4.2” mortars. He intended to use them to deadly effect now. Two platoons of Fusiliers moved in on the bridge, with one platoon attempting to move along the ditch, only to struggle against the thick, waist-high grass, as the second slipped off the road into the jungle. The mortars, about 60 yards behind them, began firing, slowly at first, but then as fast as the men could drop bombs into the tubes. The men, with fixed bayonets, charged across the bridge. The Japanese waited until the British were halfway across before opening fire. Tracers filled that little space, bullets tearing into flesh. The Chindits toppled left and right. Some crawled in their bellies, trying to get just far enough to throw their grenades upon the enemy positions. By 6.15, it was all over, the retreat was called. Calvert summoned US airstrikes. Mustangs swooped in, bombing and machine-gunning the enemy emplacements, but one Mustang mistakenly bombed a group of Fusiliers unloading mules.
Because of the unexpected opposition, Calvert would instead direct his forces to ford the Wettauk Chaung and take Mahaung and Ywathitgale, which successfully fell on June 9. The following morning, a Gurkha company attacked towards Kyaingyi and the railway to create the impression that the main attack would come from this direction while the bulk of the 3/6th Gurkhas made a wide right flank advance to attack the bridge from the rear. At dawn on the 10th, Shaw’s Gurkhas moved forward, waist deep in marsh water and mud. The bridge assault party was under the command of Captain Michael Allmand, a one-time cavalryman commissioned into the Indian Army in 1942 after escaping from Singapore. Allmand moved his men forward warily. The approaches to the bridge were narrow with the road up on a high embankment with swampy, tree-heavy low-ground flanking both sides. Coming in from the marsh, the Gurkhas set upon the bunkers at the bridge with grenades and small-arms fire, but the Japanese held their ground. At 10 am, they tried again, shooting and hurling grenades from amid waist-deep mud of the Wettauk. Allmand, who was close to shore charged. Throwing grenades to scatter the enemy, he closed in to kill three with his kukri. Rallied by his heroism, the Gurkhas rushed the remaining defenders, capturing the bridge. About 35 Japanese were killed at the bridge and the Gurkhas captured one medium machinegun and two light machineguns. In return, Chindit casualties in the encirclement and capture of the Pinhmi Bridge came to about 130 killed and wounded. By mid-afternoon, Calvert had deployed two battalions up on the Mogaung-Pinhmi Road, while a third occupied the bridge area. Conquering the brigade saw the Chindits suffer 130 casualties, while Okada’s troops had also suffered heavy casualties, yet they had successfully delayed the Chindit advance for four days, which allowed Takeda to bring the bulk of his forces back into Mogaung.
Knowing full well that the Japanese had been able to reinforce Mogaung, Calvert decided to wait for the arrival of the Chinese troops that Stilwell had sent to reinforce him; but in the meantime, he launched a successful attack against the courthouse on June 11, followed by a failed advance towards the river. To secure his right flank, Calvert had decided to send a company of South Staffords under a new replacement officer, Major “Archie” Wavell Jr, son of the venerable Viceroy, to secure the area between the road and the Mogaung River. The Staffords made good headway, but near the river, they came under heavy fire from entrenched Japanese. Wavell was hit in the wrist, the bullet almost taking the hand off; and he was then pulled out of the line and walked back to the field hospital near Gurkha village, clutching onto his hand, which was now hanging on by a sinew. That night, the surgeons at Gurkha Village were to remove the hand entirely. Wavell Jr’s war was over. In the end, the Staffords also had to pull back towards the road after the loss of their commanding officer. By June 15th, the Chinese had still not appeared, thus the Chindits ultimately had to withdraw to Pinhmi.
Back over at Myitkyina artillery was arriving by air. Two batteries plus one platoon of 75-mm. howitzers; two 105-mm., and two 155-mm. howitzers, were landed. All except two pieces with GALAHAD were kept under headquarters control. During the siege they fired 600 tons of ammunition, very rarely with massed fire. Boatner renewed his offensive on June 13th, sending almost all his forces to attack the town from all directions. The American-Chinese forces would struggle to make much progress against General Minakami’s defenses. Utilizing a system of night attack and daylight defense, heavy casualties were consequently inflicted on the enemy and large supplies of weapons and ammunition were captured and used in the defense of the city. On June 12th the Japanese hit a platoon of K Company, New GALAHAD, so hard that the company broke and re-formed on the L Company line. The portion of the Japanese thrust that hit the perimeter next to the river made most of the men "take off," but two stayed in place and repelled the Japanese with an automatic rifle and a machine gun. To the west of this little break the Japanese worked their way in close but were stopped by grenades and small arms fire.
As a result of the attacks, however, the 3rd Galahad Battalion had cut the Maingna ferry road and reached the Irrawaddy north of Myitkyina by June 17th, with the 150th and 88th Regiments also gaining up to 200 yards. The allies needed to capture the Myitkyina-Mogaung-Sumprabum road junction; but for such few gains, Boatner had lost many men and thus had to stop his attacks on June 18th. Stilwell ordered the end of all infantry attacks. Boatner replied that he would stop attacking Japanese positions until ". . . our troops are steadied and a favorable opportunity presents itself." There was reason for the troops to need steadying. A and B companies, 209th Engineers, were cut off from their main body by infiltrating Japanese. Trying to close in on them, Company C and Headquarters and Service Companies were in turn halted by Japanese. The condition of A and B Companies became critical during June 14th, for they had only one meal with them. Two of their men managed to work their way back to the block on the Sumprabum Road with news of their plight, but enemy small arms fire prevented airdrops. The isolated companies finally made their way back in small groups to the rest of the battalion over 15 and 16 June. The 3rd Battalion of GALAHAD reported trouble in effecting reorganization and enforcing orders. The Americans were not alone in their problems. Two companies of the Chinese 2/42nd which had made a small penetration into the Japanese lines on 14 June were wiped out by counterattack that night. These setbacks emphasized the nature of the Myitkyina fighting. The Allies held a ring of battalion and regimental strongpoints enclosing a similar Japanese system. Though the Allied strongpoints were close enough for the troops in one to sortie to the aid of another should that be needed, they were not so close that interlocking fire could be put down to close the gaps. Consequently, there was plenty of room for maneuver and ambush, and the inexperienced engineers and New GALAHAD troops often suffered at the hands of General Minakami's veterans. On the other hand, the Myitkyina Garrison did not emerge entirely unscathed, as they too suffered heavily, losing approximately 1000 men during the month of June alone. But that is all for today with the CBI theater as we now need to head over to New Guinea to start the Battle of Lone Tree Hill.
After the fall of Wakde, General Tagami had sent Colonel Yoshino Naoyasu’s 223rd Regiment to cross the Tor River inland to attack Arare while Colonel Matsuyama Soemon’s 224th Regiment attacked the Toem area from the other side. In the meantime, General Doe’s 163rd Regiment patrolled across Tementoe Creek and the Tor River, encountering heavy Japanese resistance at Maffin but successfully repelling some enemy counterattacks. While the 163rd strengthened its defenses on the Tor and at Arare, Doe would also see the arrival of Colonel Prugh Herndon’s 158th Regiment on May 21. General Krueger’s plan was to use this regiment in a vigorous overland drive toward Sarmi, aimed at throwing the enemy into the defensive and therefore securing the Wakde area. This decision was based upon scanty and incomplete information concerning Japanese strength and dispositions. The Japanese had no intention of abandoning Sarmi and the two airstrips between the town and the Tor without a desperate struggle.
The Americans were also finalizing their plans for an operation against Biak, codenamed Hurricane. General Fuller’s plan was to land the 186th Regiment in the Bosnek area at 7:45 on May 27th to secure the Green Beaches and its two jetties. Once the two jetties were secured, LCI's bearing the 162nd Infantry, supporting troops, and the task force reserve were to move inshore and unload. LST's were also to move to the jetties when the beach area surrounding them had been cleared by the 186th Infantry. LCM's bearing artillery, tanks, and engineering equipment were to move to the beaches as soon as channels through the coral were found or made, or to the jetties in waves following the 186th Infantry's assault companies. As soon as it reorganized ashore, the 162nd Infantry was to advance rapidly west along the coast from Bosnek to seize the three airdromes. This drive was to be supported by eight tanks of the 603rd Tank Company and the 146th Field Artillery Battalion. The fields were to be repaired quickly to accommodate one fighter group and then expanded to receive an additional fighter group, a heavy bomber group, a reconnaissance group, a night fighter squadron, and one photo reconnaissance squadron. Mokmer Drome was to be the first field developed. Brigadier-General Edwin Patrick would also replace Doe in command of the Tornado Task Force, as the latter would resume its duties as assistant commander of the 41st Division.
Admiral Fechteler’s Task Force 77 was to provide naval support and cover the assault shipping. Naval fire support was to begin at H minus 45 minutes, 6:30. From that time until H Hour, cruisers and destroyers were to expend 400 rounds of 8-inch, 1,000 rounds of 6-inch, 3,740 rounds of 5-inch, and 1,000 rounds of 4.7-inch ammunition on targets in the airfield area west of the landing beaches. After H Hour the cruisers were to continue intermittent fire on the airfields, bombard targets of opportunity, and respond to calls for support from the forces ashore. Because there were many known or suspected Japanese gun emplacements along the south shore of Biak, counterbattery fire was to take precedence over all other types of fire. Bombardment of the landing beaches was also to begin at H minus 45 minutes. Five destroyers were to bombard the beaches and adjacent areas until H minus 30 minutes, when they were to move westward to join the cruisers firing on the airfield area. Then four other destroyers were to continue beach bombardment until H minus 3 minutes. Total ammunition allowance for beach bombardment was 4,900 rounds of 5-inch and 4.7-inch shells, while 40-mm. and 20-mm. ammunition was to be expended at the discretion of individual ship commanders. Rocket and automatic weapons fire from three rocket-equipped LCI's and two SC's was to provide close support for the assault waves. This fire was to begin at H minus 5 minutes and was to last until H Hour or until the initial wave was safely ashore.
Meanwhile General Kenney would toss 52 B-24’s to bomb the beaches just before the landings. Additionally, medium bombers and fighters from 5th Air Force would cover the force from the air; and from May 17th onwards, the bombings on Biak’s airfields would increase sharply in violence to soften up its defenses. As elsewhere along the absolute defense zone perimeter, primary emphasis was laid upon the construction of airfields. Between December 1943 and the enemy invasion of Hollandia in April 1944, two of three projected fields on southern Biak were completed and put into operational use by planes of the Navy's 23rd Air Flotilla. Their usefulness ended almost immediately, however, when the enemy's vastly superior air forces began operating from Hollandia bases. As in the Wakde-Sarmi sector, the concentration of effort on airfield construction until the Hollandia invasion resulted in dangerously delaying the preparation of ground defenses against enemy amphibious attack. In the five weeks which elapsed between the Hollandia and Biak invasions, the Biak garrison forces, under able leadership and by dint of desperate effort, succeeded in organizing a system of strong cave positions, which proved highly effective after the enemy landing. However, time, equipment and manpower were so short that defensive preparations could not entirely be completed. Some 15-cm naval guns, brought to Biak immediately after the Hollandia invasion to strengthen the coast defenses, were still unmounted when the island was attacked.
On May 23rd, the 158th advanced west from the Tor River Bridgehead. The advance of Company L met increasingly strong resistance. Japanese defenses were centered around three small, brush-bordered lakes near the beach about 1,800 yards west of the Tor. The rest of the 3rd Battalion, 158th Infantry, across the Tor before 1130, quickly moved forward to assist Company L, which had been pinned down along the main coastal track west of the lakes by Japanese machine gun and rifle fire. Company K pushed up to the left flank of Company L, while Company I moved toward L's rear. With the aid of mortar fire from the 81-mm. weapons of Company M, Companies K and L were able to push gradually forward during the afternoon, advancing on a front about 400 yards wide. Finding that the attack was not progressing as rapidly as he had expected, Colonel Herndon ordered his 1st Battalion across the Tor. The 1st Battalion did not start moving until 1400 and could not get far enough forward to join the attack before dark. Tanks would probably have been of great help to the 3rd Battalion, but by the time the mediums of the 1st Platoon, 603rd Tank Company, moved across the Tor, the forward infantry troops had already halted for the night. In the end, Companies L and K would dig in for the night across the main coastal track about 400 yards east of Maffin.
The following morning, after an ineffective mortar and artillery bombardment, Herndon resumed the attack. Despite the lack of extended artillery support, Companies K and L moved out as planned at 7:30. Company L, on the right, advanced along the beach encountering only scattered rifle fire but Company K, on the main road, had hardly started when Japanese machine gun and rifle fire from concealed positions in a wooded area on the left front halted its advance. Unable to gain any ground, Company K called for tank support. Two tanks, together with a flamethrower detachment from Company B of the 27th Engineers, arrived at Company K's lines about 1000. With the flamethrowers and tanks blasting the way, the infantrymen overran the Japanese defenses, killing ten of the enemy and capturing two machine guns. The remainder of the Japanese force, probably originally some forty men strong, disappeared into the jungle south of the road, whence scattered rifle fire continued to harass Company K. Company L reached the outskirts of Maffin No. 1 about 1400. The movement had been slow, not as a result of Japanese opposition but because the battalion commander did not believe it prudent for Company L to advance far beyond Company K. Despite the return of two companies, most of Colonel Kato’s engineers would have to withdraw behind the Tirfoam River against such heavy firepower. Captain Saito’s reconnaissance unit, meanwhile, retreated to the jungles south of Maffin alongside one engineer company, which was under Kato himself.
Over the Tirfoam River, however, the Americans were again stopped by the tenacious engineers, which again forced Herndon to request tank support. As the tanks moved into position elements of the Right Sector Force, comprising Captain Saito's men of the 1st Battalion, 224th Infantry and an engineer company, charged out of the jungle. The Japanese were under Colonel Kato, Right Sector Force commander, who was killed as he personally led a small detachment against the American tanks. The enemy was quickly thrown back with heavy losses by the combined fire of the four tanks and Company L's riflemen and machine gunners. However, under cover of their infantry attack, the Japanese had dragged a 37-mm. anti-tank gun forward out of the jungle. As the enemy infantrymen withdrew to the southwest after the death of Colonel Kato, the anti-tank gun opened fire. It was soon destroyed and its crew killed, but not before three of the American tanks had been so damaged that they had to be withdrawn for repairs.
Facing such heavy resistance, Herndon then sent his 1st Battalion to carry out a deep envelopment to the south across the Tirfoam, yet these troops would similarly be unable to break through by nightfall. After killing 28 men and wounded 75 others, Kato’s force allowed Tagami to dispatch the 2nd Battalion, 223rd Regiment to reinforce the Ilier Mountains line. On the morning of May 25, Major Matsuoka Yasake also arrived there with an infantry company to assume command of the remainder of Kato’s forces. Meanwnhile Yoshino had crossed the Tor River, 3 days behind schedule and to the east, Matsyuama was assembling on the right bank of the Tementoe River. Herndon relieved his 1st Battalion with the 3rd and then pushed west with the 2nd Battalion following behind them. The next objective for the 158th was Long Tree Hill.
Lone Tree Hill, known to the Japanese as Mt. Ilier, had been named for a single tree which was depicted on its crest by the map then employed by the Americans. Actually, the hill's coral mass was covered with dense rainforest and jungle undergrowth. Lone Tree Hill was about 175 feet high, 1200 yards long north to south, and 1100 yards wide east to west. The north side dropped steeply to a rocky shore on Maffin Bay. The hill's eastern slope was fronted by a short, violently twisting stream which was promptly dubbed the "Snaky River" by the 158th Regiment. The main road curved away from the beach to pass south of the Snaky River and Lone Tree Hill through a narrow defile. The southern side of this defile was formed by two noses of Mt. Saksin , a terrain feature about 100 feet higher than Lone Tree Hill. The more westerly of these noses was named "Hill 225", known to the Japanese as Mt. Sento after its height in feet. No name was given to the eastern ridge line, which pointed toward Lone Tree Hill from the southeast. There was a small native village at the eastern entrance to the defile and another at the pass's western outlet. Mt. Saksin was a name given to an indefinitely outlined hill mass which forms the northern extremity of the Irier Mountains, extending inland from the coast at Lone Tree Hill. The name Saksin was specifically applied to a prominent peak about 2,000 yards due south of Lone Tree. On or about May 23rd General Tagami had moved his headquarters into the Mt. Saksin area, apparently on the southwest side of the central peak.
Herndon forces continued the advance through the abandoned enemy positions, albeit without tank support, for they could not cross the fragile Tirfoam bridge. In the afternoon, the Americans were finally halted below the southernmost bend of the Snaky River, subjected to heavy machine-gun fire and an intermittent artillery bombardment. General Patrick, who had succeeded to the command of the TORNADO Task Force during the morning, was informed of the opposition encountered by the 1st Battalion. He ordered the advance stopped for the night and instructed the 158th Infantry to remain well east of the Snaky River so that American artillery could register on the native village and the defile without endangering the forward troops. Harassed by a few artillery shells, which by now had been recognized as originating from Japanese 70-mm. or 75-mm. weapons, the 1st Battalion pulled back about 500 yards east of the Snaky. A perimeter was set up with the battalion's left resting on the road and its right on the beach. The 2nd Battalion established a series of company perimeters back along the road to the east. Casualties for the day had been 22 men killed and 26 wounded, almost all in the 1st Battalion, while about 50 Japanese had been killed. When the attack orders for the day had been issued, it had been hoped that the 1st Battalion could reach the top of Lone Tree Hill before nightfall. Since the unexpectedly strong enemy opposition had prevented the realization of this hope, plans were made to continue the advance westward on the 26th. The ultimate objective was the east bank of the Woske River, 2,000 yards west of Lone Tree Hill, and the intermediate objective was the native village at the eastern entrance to the defile. The advance was to be preceded by naval shelling of the northern slopes of Lone Tree Hill from 6:30 to 7:00. A fifteen-minute artillery preparation was also to precede the advance, and the infantry was to start moving at 8:45.
The next morning, naval fire started ten minutes late. Two destroyers lying offshore shelled the northern slopes of Lone Tree Hill and the Maffin Bay area, firing on known or suspected enemy defensive positions and assembly points. After a twenty-minute bombardment the two support vessels withdrew. Artillery fire did not begin until 8:30. The time lag gave the Japanese ample opportunity to prepare for the infantry attack which had been heralded by the destroyer fire. The artillery, aiming its shells into the defile and against the eastern slopes of Lone Tree Hill, ceased firing about 8:45. A few moments later the 1st Battalion, 158th Infantry, Company B again leading, started moving westward. The infantry's line of departure was nearly 1,000 yards east of the village at the southeast foot of Lone Tree Hill, and the advance had to be slow because the road ran through heavily jungled terrain. The enemy therefore had sufficient time to reoccupy positions in the defile and on Lone Tree Hill which might have been vacated during the American artillery barrage. The value of both the naval and artillery bombardment had been lost.
Herndon’s 1st Battalion moved once again against Lone Tree Hill. Company B moved forward to the point at which it had been held up the previous afternoon and was again stopped--this time by fire from the southeastern corner of Lone Tree Hill. Company D's heavy machine guns were brought up to spray a densely wooded area in front of the point rifle platoon. The fire dispersed the Japanese riflemen, and Company B moved forward again. Less than 100 yards of ground had been gained when the company again encountered machine gun and mortar fire originating in the native village. Company A, initially off the road to the right rear of Company B, turned north to the mouth of the Snaky River. One platoon crossed at the river mouth at 1030 but was quickly forced back to the east bank by Japanese machine gun fire from the rocky beach below the north face of Lone Tree Hill. Artillery support was called for, supplied, and proved successful in stopping the enemy fire, and about 1:50 all Company A crossed the Snaky. Orders were to move down the west side of that stream to establish contact with Company B and to send one platoon up the eastern slope of Lone Tree Hill to probe enemy positions. Other efforts were meanwhile being made to scatter the Japanese opposing Company B. Company E moved up to the left flank of Company B and on the south side of the main road. The combined efforts of the two rifle companies proved insufficient to dislodge the Japanese from their positions at the eastern entrance to the defile, and the enemy fire forced the American units to seek cover. Company F was therefore ordered to pass through B's left flank and proceed to Hill 225 to take the Japanese positions from the rear. Company F's attack could not be started before dark and Company A, moving up the west side of the Snaky, was unable to relieve much of the pressure on Company B. Finally, Company A was forced for a second time to withdraw to the east bank of the river as a result of enemy fire from Lone Tree Hill. Tanks would have been of great help to Company B, but the bridge over the Tirfoam could not bear their weight, and the road west of the stream was in such disrepair that tanks probably could not have negotiated it.
Only Company A would manage to cross the Snaky River through much effort, yet it would be unable to relieve the pressure from Company B’s front and would have to retreat by the end of the day. To prevent further casualties from being inflicted by Japanese patrols, which were expected to roam around the flanks of the forward elements during the night, a semicircular perimeter was ultimately established. Although Herndon’s attacks on May 26th had been completely unsuccessful, the 158th Regiment had located and probed some of the principal Japanese defenses in the area and could now be ready to launch a more effective assault.

General Vinegar Joe was experiencing some major setbacks, but it looked like Myitkyina was as good as his. However the American officers' reports of how difficult the going was for the Chinese was quite disheartening. Over in New Guinea, the allies were yet again faced with a great obstacle, now in the form of One Tree Hill.
