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.

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.
