Last time we spoke about the atomic bombing of Nagasaki. In the summer of 1945, Japan faced its most devastating siege, characterized by an aerial campaign called "Starvation" that crippled its industrial capabilities. As resources dwindled and chaos reigned, the Allies intensified their firebombing efforts, targeting major cities. By July, Japan was on the brink of collapse, culminating in the atomic bombing of Hiroshima, where over 140,000 lives were altered or lost in a blinding flash. As the nation reeled from the destruction, the Japanese leadership was torn between surrender and continuing the fight. They faced not just the threat of American bombs, but also a Soviet invasion looming on the horizon. Days after Hiroshima, the atomic bomb "Fat Man" was dropped on Nagasaki on August 9, resulting in catastrophic casualties and extensive industrial losses. This attack further devastated an already weakened Japan, leaving the Emperor and his government grappling with the dire consequences.

August 9 stands as a catastrophic day in Japanese history. On this day, the nation faced the devastating impact of a second atomic bomb dropped on Nagasaki, along with the relentless Soviet invasion of Manchuria. Admiral Ivan Yumashev’s Pacific Fleet moved to disrupt Japan's maritime communications in the Sea of Japan and provide support for offensive operations. At the same time, Soviet air forces targeted cities across Northeast Asia, striking both Manchuria and North Korea, as well as Japanese convoys in the Sea of Japan. General Twinning led a diversionary B-29 raid on Amagasaki, followed by a significant attack involving 108 aircraft on the rail yards at Marifu. In addition, Admiral Halsey’s 3rd Fleet launched more strikes against airfields in northern Honshu and Hokkaido, where U.S. intelligence suspected a large Japanese air fleet and commando force was preparing for a desperate mission to Okinawa. Japanese paratroopers were gearing up for a new mission, codenamed Ken-go, but this time their target wasn’t Okinawa. Similar to the earlier May 24 Raid on Yontan Airfield, Lieutenant General Sugawara Michio's Giretsu Kuteitai, also known as the “Heroic Paratroopers,” set their sights on the B-29 complex in the Mariana Islands for nighttime suicide raids. This operation marked the second planned assault on bases within the Mariana Islands, specifically aimed at destroying B-29 bombers. The plan involved deploying 60 transport aircraft to deliver 900 commandos during the nights of August 19 to 23. Around 300 personnel from Lieutenant Commander Daiji Yamaoka’s 1st Kure Special Naval Landing Force initiated preparations at the end of June. Originally established for submarine-delivered raids on U.S.-held islands, these forces were now adapted to be flown in 30 Mitsubishi G4M 'Betty' twin-engine bombers, which had the necessary range for an unrefueled, one-way trip to the Marianas. The raid was initially scheduled for July 24. However, ten days earlier, U.S. carrier-based warplanes had attacked Misawa naval air base on Honshu Island, damaging or destroying many of the operation's bombers. Consequently, the raid was postponed to August 19, with the addition of 30 transport planes and 300 paratroopers from the army’s 1st Raiding Regiment. Ultimately, however, on August 15, Japan surrendered, and Operation Ken-go was cancelled.

Meanwhile, Admiral Shafroth's Bombardment Group unleashed heavy damage on the Kamaishi steel mill. The day after, to assist the Soviets, Halsey ordered additional airstrikes on northern Japanese airfields, causing extensive destruction. However, these were not isolated incidents; they were part of a sustained air-sea siege that had been intensifying for several months. The Allied blockade of Japan had severely impacted food imports, and industrial activity had nearly ground to a halt due to the ongoing blockade and bombings. By this point, six of Japan's ten largest cities had been completely destroyed, and over sixty smaller cities had been reduced to ashes from relentless incendiary raids. This scenario was a powerful manifestation of War Plan Orange in action. More critically, with the reality of Hiroshima's destruction echoing loudly, the Japanese government now grappled with the impending threat of complete annihilation, a grim reality they had never faced before in this war. Though they had recognized their defeat with the loss of Saipan and the initial Yawata raid, the stubborn resolve of the Japanese leadership had pushed them to prolong the conflict for an agonizing 14 months, clinging to the hope of a different outcome.

Many now believed that peace was the only path to survival for the Japanese nation. As the crisis intensified, Prime Minister Suzuki and his cabinet engaged in heated discussions. He sought to persuade War Minister General Anami Korechika and Chief of the Army General Staff General Umezu Yoshijiro to accept the Potsdam Declaration on August 9. However, Suzuki and the militants could only agree that if there were any surrender, then it should ensure that the "national polity" or imperial family would continue in any postwar settlement. Anami and Umezu pushed for further, more favourable conditions. First, Japan would demobilize and disarm any IJA or IJN forces overseas. Second, Japanese courts would prosecute any war criminals. Third, after surrender the Allies would not occupy Japan. Chief of the Navy General Staff, Admiral Toyoda Soemu, agreed with Anami and Umezu.

To break this deadlock, it became necessary to involve the Emperor directly. Around 2:00 AM on August 10, the cabinet convened with Emperor Hirohito, who ultimately agreed to accept the Potsdam Declaration and ordered an end to all military efforts, initiating the surrender process. Faced with no viable alternatives, all present reached a unanimous agreement. That morning, the Japanese government, through Swedish and Swiss intermediaries, sent an offer to accept the Potsdam Declaration, stipulating one condition: there would be no change to Japan's government structure, with Hirohito retaining his title as Emperor and sovereign ruler. Months afte the war Hirohito said this about his decision to surrender “The main motive behind my decision at that time was that if we . . . did not act, the Japanese race would perish and I would be unable to protect my loyal subjects [sekishi—literally, “children”]. Second, Kido agreed with me on the matter of defending the kokutai. If the enemy landed near Ise Bay, both Ise and Atsuta Shrines would immediately come under their control. There would be no time to transfer the sacred treasures [regalia] of the imperial family and no hope of protecting them. Under these circumstances, protection of the kokutai would be difficult. For these reasons, I thought at the time that I must make peace even at the sacrifice of myself.”

Simultaneously, a new military campaign was underway, and several units of General Yamada’s Kwantung Army were unexpectedly caught off-guard in Manchuria. In response, he implemented emergency measures and ordered commands to proceed with their plans for delaying operations. Upon learning of the Soviet declaration of war and the subsequent invasion led by Marshal Vasilevsky’s Far East Command, Tokyo decided to place General Kozuki’s 17th Area Army under the Kwantung Army. Furthermore, they instructed General Okamura Yasuji’s China Expeditionary Army to transfer one army headquarters, along with six divisions and six brigades, to support this effort.

As directed by Tokyo, the primary objective of the Kwantung Army was to defend Japanese territory in Korea. However, by the end of the first day of conflict, several border observation units had been completely destroyed while attempting to defend their positions. In the east, Lieutenant General Shimizu Noritsune’s 5th Army, supported by the reinforced 128th Division, was confronting the main assault by Marshal Meretskov’s 1st Far Eastern Front. To the south, Lieutenant General Murakami Keisaku’s 3rd Army was engaged in defending against multiple penetrations along the border. In the northern sector, the 134th Division at Chiamussu was withdrawing towards Fangcheng, as planned, while flames engulfed Japanese houses in the city. General Uemura’s 4th Army was preparing to face what they expected to be the main assault from General Purkayev’s 2nd Far Eastern Front. Meanwhile, the 119th Division had already departed Hailar for Wunoerh, leaving only the 80th Independent Mixed Brigade behind. To the west, Lieutenant General Hongo Yoshio’s 44th Army was confronting the formidable armored spearhead of Marshal Malinovsky’s Transbaikal Front. Southwest of their position, the 108th Division was redeploying to the Chinhsien area. On August 10, the offensive led by Vasilevsky continued, as Colonel General Ivan Managarov’s 53rd Army began crossing the border behind the now distant 6th Guards Tank Army. Recognizing that the 44th Army was not prepared to engage the overwhelming enemy armor in guerrilla warfare across the expansive terrain of western Manchuria, Gener
