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, General Ushiroku made the independent decision to order Hongo to retreat to the Dairen-Hsinking line. This was where Lieutenant General Iida Shojiro’s 30th Army was already establishing defensive positions. This decision contradicted Yamada’s main strategy, which called for delaying the enemy advance at the borders. Faced with what they deemed an illegal order, the Kwantung Army Headquarters convened an urgent staff conference. During this meeting, several opinions emerged: a sudden shift from established plans would likely create confusion; any attempt to counterattack after a withdrawal would likely fail if the enemy advanced quickly; and abandoning forward airfields prematurely would enable the enemy to advance unimpeded. To most participants, General Ushiroku’s decision seemed to deliver a potentially fatal blow to the overall operational direction of the Kwantung Army Headquarters. However, since the 44th Army had already begun its withdrawal as ordered by General Ushiroku, Kwantung Army Headquarters was left with a fait accompli. Thus, they felt compelled to uphold the decision of the Third Area Army Commander, which was subsequently approved by General Yamada.

Meanwhile, General Pliyev’s cavalry-mechanized units advanced rapidly toward Kalgan and Dolonnor, reaching the foothills of the Grand Khingan Mountains. General Danilov’s 17th Army also continued to encounter weak resistance, covering an additional 40 kilometers. General Lyudnikov’s 39th Army bypassed the encircled 107th Division in the Halung-Arshaan and Wuchakou Fortified Regions. Here, the 5th Guards Rifle Corps moved toward Solun and Tepossi, while the 113th Rifle Corps advanced southeast toward Wangyemiao. The 94th Rifle Corps had to divert southward to support the 124th Rifle Division. In the east, General Luchinsky’s 36th Army launched ongoing attacks against Hailar, with the 2nd Rifle Corps bypassing it to the east. Meanwhile, General Kravchenko’s 6th Guards Tank Army reorganized its right-wing column and began crossing the Grand Khingan Mountains during the night, with both columns entering the central Manchurian plain by August 11. To the east, Meretskov continued his offensive. The 17th, 65th, and 72nd Rifle Corps of General Krylov’s 5th Army advanced swiftly west and south, ultimately securing Machiacho, Laotsaiying, Suiyang, and Suifenho. This maneuver widened the zone of penetration to 75 kilometers and forced the 126th and 135th Divisions to withdraw their main forces to Yehho. In support, General Beloborodov’s 1st Red Banner Army to the north broke through into open terrain, pushing rapidly westward to occupy parts of the cities of Pamientung and Lishuchen, along with their vital bridges across the Muleng River. Further south, General Chistyakov’s 25th Army captured Tungning and successfully reduced its fortified region. Units in that area also secured Tumentzu, Hunchun, and Wuchiatzu. Lastly, General Zakhvatayev’s 35th Army continued its operations far to the north. The 264th Rifle Division and the 109th Fortified Region seized Hutou and initiated a movement west along the railroad toward Hulin, while the 363rd and 66th Rifle Divisions pressed on with their advance northwestward.

In northern Manchuria, General Purkayev continued his main assault, with General Mamonov’s 15th Army reconnoitering key enemy strongholds south of the Amur River. After successfully crossing the river, the 34th Rifle Division and the 203rd Tank Brigade occupied Lopei and advanced through Fenghsiang to bypass the Hsingshanchen Fortified Region, leaving a force behind to reduce it. Meanwhile, the 361st Rifle Division captured Tungchiang, and the 388th Rifle Division secured Chienchingkou, preparing for an advance toward Fuchin. In support of these operations, General Pashkov’s 5th Rifle Corps cleared Japanese forces from the Jaoho Fortified Region, while General Teryokhin’s 2nd Red Banner Army was preparing to launch its offensive the following morning. On August 11, forward units landed at Heiho, Aihun, and Holomoching under the cover of artillery fire, quickly establishing a beachhead as additional forces crossed the Amur. However, due to a lack of crossing equipment, it took five days to transport all units across the river. Consequently, Teryokhin had to commit his forces piecemeal against the 123rd Division and the 135th Independent Mixed Brigade. This was not the only new offensive operation initiated by Purkayev on this day. A new target had emerged: South Sakhalin, known as Karafuto to the Japanese. As per Vasilevsky’s plans, Major-General Leonty Cheremisov’s 16th Army was deployed on North Sakhalin and along the mainland coast of the Tatar Strait, stretching from Sovetskaya Gavan to Nikolaevsk-on-Amur. If the invasion of Manchuria continued to progress favorably, this force was set to attack the Japanese-controlled portion of the island alongside the Northern Pacific Flotilla, commanded by Vice-Admiral Vladimir Andreyev, which was prepared to conduct amphibious operations against Esutoru and Maoka on the island's west coast.

Opposing the Soviet forces, General Higuchi of the 5th Area Army positioned Lieutenant General Mineki Toichiro’s 88th Division in the southern part of South Sakhalin, with only the 125th Regiment stationed to the north. Sakhalin shared many characteristics with several of the Manchukuoan border areas, presenting challenging terrain for mechanized warfare. The only viable invasion route south from the border at the 50th Parallel followed the Poronay River, located more or less in the center of the island. This river flows southward, flanked to the east and west by forested mountain ranges, as well as countless swamps and bogs. Both sides recognized the strategic importance of this potential invasion route and constructed extensive fortification networks. The Japanese fortifications were collectively known as the Koton, or Haramitog, fortified region. These defenses were built in three interlinked layers, with their western flanks anchored in the mountain range and eastern flanks in the wooded, swampy river valley. The permanent defenses spanned approximately 12 kilometers in frontage and extended up to 30 kilometers in depth, containing over 350 bunkers, pillboxes, artillery positions, and similar fortifications. These were protected by an elaborate network of infantry trenches, anti-tank ditches, minefields, and barbed wire. The heavy forest and brush made it challenging to locate these defenses. While enough vegetation had been cleared to allow for effective defensive fire, sufficient cover remained to obscure them from an attacking force. Consequently, the 16th Army would confront these formidable defenses without the advantage of surprise.

At daybreak on August 9, reports emerged that the Soviet Army had unexpectedly invaded Manchuria from multiple directions. By 8:00 AM, telegraph lines were cut near Handa, a village located at the center of the Russo-Japanese border in Sakhalin. An excellent military road connected Handa to Kamishikuks, a region known as the Central Military Road area. At the same time, reports indicated that enemy forces were attacking the observation posts in this area. On August 10, observation posts were forced to withdraw as the Soviet Army gradually advanced toward our main position in the Happo Mountains, situated about 10 kilometers south of the border. That evening, it was reported that the 125th Infantry had engaged in a skirmish, during which the Isunisawa Platoon, fighting near the Handa River bridge for over five hours, was wiped out. On that same day, the commander of the Fifth Area Army declared that not only had the Army engaged Soviet forces, but civilians in the area, including office workers and laborers, had also joined the battle in a desperate attempt to halt the advancing Soviet Army. By August 13, the National Volunteer Combat Teams were summoned. The recruitment of these volunteer combat teams from the general populace was unique to the Sakhalin campaign, aimed at creating the appearance of military readiness to deter the Soviet advance.

Additionally, the 125th Regiment executed demolitions while retreating to establish stronger defensive positions on the western flank of Happo Mountain, northwest of Furuton. Given the unexpectedly favorable developments in Manchuria, the invasion of South Sakhalin was authorized on August 10. General Yumashev further directed Vice-Admiral Andreyev’s naval forces to commence attacks on both South Sakhalin and the Kuriles. Major General Georgii Dziuba’s air forces joined the effort, conducting reconnaissance flights over key Japanese ports that revealed Toro and Esutoru were almost entirely unprotected. In the early hours of August 11, the 56th Rifle Corps crossed the border and began its main advance along the central military road but encountered resistance at Handa, where around 100 defenders held them up for an entire day. Back in northern Manchuria, the 5th Rifle Corps embarked on a challenging march southwest toward Paoching, while Mamonov launched a bombing raid followed by an attack on Fuchin, which ultimately fell after a coordinated tank-infantry assault. Concurrently, the 4th Army headquarters and the bulk of the 149th Division received orders to retreat from Tsitsihar to Harbin. To the south, the 112th Fortified Region and the 6th Field Fortified Region crossed the Muleng River south of Mishan during the night. In the following days, they collaborated with units from the 35th Army to secure the Mishan Fortified Region.

More importantly, the 26th and 59th Rifle Corps successfully secured Pamientung and Lishuchen, initiating a pursuit of withdrawing Japanese forces to the west and southwest. On August 11, the 5th Army advance continued, with reinforced forward detachments of the 65th and 72nd Rifle Corps reaching the Muleng River and preparing for an advance on Mutanchiang. At this juncture, Meretskov reassessed the situation and determined that his best opportunity for successful exploitation in the front zone lay within the 25th Army area. Consequently, he attached the 17th and 88th Rifle Corps to this command and placed the 10th Mechanized Corps in army reserve. This allowed the 17th and 39th Rifle Corps to commence a coordinated advance toward Wangching, Tumen, Tunhua, and Kirin. Looking west, Pliyev’s units continued to encounter minimal resistance. The 17th Army was finally nearing the western foothills of the Grand Khingan Mountains. The lead brigade of the 5th Guards Tank Corps reached Lupei, while the 7th Guards Mechanized Corps completed its crossing of the Grand Khingan Mountains. The 39th Army maintained its holding operations against the Halung-Arshaan and Wuchakou Fortified Regions, coupled with main advances toward Solun and Wangyemiao. The 2nd Rifle Corps and the 205th Tank Brigade advanced along the railroad to Yakoshih. The 94th Rifle Division, supported by air and artillery, launched an assault and captured the southwestern portion of Hailar city before being reinforced by the entire 86th Rifle Corps. Meanwhile, the Soviet operational group on the right flank of the 36th Army broke through Japanese resistance at Manchouli, moving eastward along the rail line to join the Soviet forces besieging Hailar.

As the Soviet armored units in the west made an unexpectedly swift advance, they were anticipated to reach Hsinking by August 15. On this same day, Yamada decided to relocate his headquarters to Tunghua. Additionally, during the night, a small naval force successfully conducted an assault landing at Yuki in North Korea, securing the port unopposed on August 12. Simultaneously, the 393rd Rifle Division pushed south into North Korea, quickly reaching Yuki before continuing toward Rashin. There, another small naval force landed on August 12, facing minimal resistance except for artillery fire. Meanwhile, the 25th Army advanced up to 40 kilometers in its main march southwest, prompting the commitment of the 10th Mechanized Corps to exploit further toward Wangching and beyond. The 5th Army had to eliminate a strong enemy position east of Taimakou before it could resume its advance to Mutanchiang. The 1st Red Banner Army pressed forward relentlessly, with the 26th Rifle Corps successfully bypassing Tzuhsingtun to advance on Hsientung, cutting the Linkou-Mutanchiang railroad line. The 363rd Rifle Division occupied Mishan while the 264th Rifle Division secured Hulin. The 171st Tank Brigade began a challenging advance southwest toward Chiamussu as the 15th Army reduced the Fuchin fortified region. Forward detachments of the 2nd Red Banner Army engaged Japanese advanced positions south of Holomoching and north of Aihun. After reducing Handa, the 56th Rifle Corps commenced an advance toward Furuton, although it faced delays from small enemy forces. Furthermore, in western Manchuria, Pliyev’s Soviet-Mongolian formations and the 17th Army continued their advance through Inner Mongolia largely unopposed for the next two days. Throughout 12 and 13 August on the Trans-Baikal Front's right flank, the Soviet-Mongolian formations of General Pliyev swept across the Inner Mongolian deserts towards Dolonnor and Kalgan at a rate of ninety to one hundred kilometers a day, rudely shunting aside local cavalry forces. Pliyev's principal concern was providing his forces in the vast desert wastes sufficient food, fuel, fodder, and water.

The 6th Guards Tank Army had to temporarily halt its advance as the 7th Guards Mechanized Corps reached Tuchuan. This pause was necessary due to severe fuel shortages, requiring an increase in fuel supplies before the offensive could resume. This situation allowed Ushiroku to withdraw the 63rd and 117th Divisions before they could be engaged. However, the 107th Division was less fortunate, as it was attacked by the 5th Guards Rifle Corps on the road to Solun. On the northern flank, the 36th Army continued its siege of the Hailar fortifications while the 2nd Rifle Corps seized Yakoshih and advanced up to Wunoerh. That day, Japan also received the initial Allied response to its surrender offer, penned by Secretary of State James Byrnes and approved by the British, Chinese, and Soviet governments. A critic of the Japanese imperial system, Byrnes insisted on an unconditional surrender but remained ambiguous regarding the future of the imperial family’s position. The response included a statement that Japan's future form of government should be “established by the freely expressed will of the Japanese people.” Thus, even though the Soviet and Chinese governments aimed for the abolition of the imperial system, the Japanese could choose to retain their emperor, and likely would. Meanwhile, Secretary Stimson urged President Truman to accept the peace offer immediately, believing that, without an organized surrender supported by the emperor, U.S. forces would face “a score of bloody Iwo Jimas and Okinawas” across China and Southeast Asia. He cautioned that without the immediate capitulation of the Imperial Japanese Army and Navy, rogue military commanders might continue to resist. Retaining Hirohito would also aid Allied efforts to achieve a swift and orderly reconstruction while maintaining a compliant populace.

The Japanese cabinet deliberated over the Allied response, with Anami and Suzuki, among other key military figures, arguing for its rejection unless an explicit guarantee for the imperial system was provided. Ultimately, however, Foreign Minister Togo and Marquess Kido Koichi succeeded in persuading Suzuki to support the acceptance of Byrnes' reply. Meanwhile, President Truman issued instructions prohibiting any further atomic weapons from being dropped on Japan without his approval, and he later ordered a complete halt to all bombings. Despite this, Halsey’s 3rd Fleet remained in the area, preparing to launch additional strikes. Admiral Rawlings’ Task Force 37 unfortunately had to retire at this point, though a token force was integrated into Admiral McCain’s Task Force 38 to ensure British support until the end.

The Olympic timetable had called for Third Fleet to retire to Eniwetok and Manus in mid-August, but late on the night of August 10 Missouri intercepted a cryptic radio transmission: “Through the Swiss government, Japan has stated that she is willing to accept Allied surrender ultimatum at Potsdam, provided they can keep their Emperor.” Halsey had long predicted an early Japanese collapse, and had accordingly kept his logistic pipeline full. The following morning, August 11, flagships Missouri and King George V refueled simultaneously alongside oiler USS Sabine. Halsey recalled, “I went across to the ‘Cagey Five’ as we called her, on an aerial trolley, just to drink a toast with Vice Admiral Rawlings.” Although Japan teetered near collapse, TF-37 lacked its own fast oilers and would have to retire immediately. With Nimitz’s permission Halsey offered to sustain a token British force with Third Fleet so that the Royal Navy would be in “at the death.” Rawlings enthusiastically accepted. After replenishment, King George V, Indefatigable, Gambia, Newfoundland, and ten destroyers were re-designated TG-38.5 and absorbed into McCain’s TF-38. The rest of TF-37, under Vian, reluctantly retired for Manus. In a truly desultory attack the following day, August 12, a single Japanese plane penetrated Buckner Bay, Okinawa undetected and torpedoed TF-95’s just-arrived battleship Pennsylvania. Twenty Americans were killed, while Oldendorf and nine others were wounded. Back off Honshu, Halsey canceled August 12 strikes due to a typhoon. Late that night Third Fleet intercepted a confusing and ambiguous radio bulletin announcing that Japan had, with qualifications, accepted Allied terms. After a heated staff conference Halsey decided that, without firmer information, the following day’s strikes were still on. Nevertheless, the prolonged negotiations were causing the Third Fleet considerable logistical problems; Halsey recalled, “Our galleys were reduced to serving dehydrated carrot salad. If the war was over, we could provision on the spot; if it was not, we would have to retire, reprovision, and return.”

That night, a group of officers led by Major Hatanaka Kenji and Colonel Arao Okikatsu approached Anami, seeking his backing for a coup d'état to prevent Japan's surrender. Anami refused, leaving Hatanaka’s conspirators to attempt the coup on their own. At the recommendation of American psychological operations experts, B-29 bombers spent August 13 dropping leaflets over Japan detailing the Japanese offer of surrender and the Allied response. In stark contrast, that same day, McCain’s newly Anglo-American TF-38 launched 1,167 sorties against Tokyo, expending 372 tons of bombs and 2,175 rockets. Only seven planes and one pilot were lost, none to combat. Airborne opposition was virtually nil, as Lieutenant-General Kanetoshi Kondo, commander of Tokyo’s defending 10th Hiko Shidan, “failed to urge his men to press the attack to the utmost, because it seemed absurd to incur additional losses with the war obviously lost and its termination due in a matter of days.” Simultaneously, Suzuki’s cabinet debated their reply to the Allied response late into the night but remained deadlocked. Back in Manchuria, on August 13, the 6th Guards Tank Army resumed its offensive by pushing reconnaissance units toward Tungliao and Taonan.

The 39th Army continued its assault on Japanese units at Halung-Arshaan, while the 5th Guards Rifle Corps attacked and captured Solun. To the north, as the battle for Hailar raged on, the 2nd Rifle Corps engaged the determined 119th Division for control of the Grand Khingan passes west of Pokotu, achieving little progress over the next two days. Looking east, the 2nd Red Banner Army gathered sufficient forces to resume its offensive, successfully penetrating the defenses of the 123rd Division at Shenwutan and Chiko. They destroyed small Japanese outposts at Huma and Santaoka, further pushing the 135th Independent Mixed Brigade toward the main fortified region at Aihun. Additionally, the 15th Army reduced the fortified positions at Fuchin, while the 171st Tank Brigade continued its advance toward Chiamussu. To the south, the 66th Rifle Division finally occupied Tungan, cutting the highway and railroad to Hutou. Meanwhile, the 59th Rifle Corps reached and secured Linkou before turning south toward Mutanchiang. Advance elements of the 26th Rifle Corps attacked and occupied the railroad station at Hualin, though they could not secure crossing sites over the Mutan River due to the fierce resistance of a single battalion. During the night, heavy Japanese counterattacks forced Soviet forces back to a hill northeast of Hualin. More importantly, while the 45th Rifle Corps continued to reduce remaining Japanese strongpoints in the Volynsk, Suifenho, and Lumintai centers of resistance, the bulk of the 5th Army advanced 30 kilometers along the road and rail line, successfully approaching the outer fortifications of Mutanchiang by nightfall. Even farther south, the 25th Army pushed southwestward, with its three formations sharing a single road along the military rail line through the mountainous, heavily wooded area from Laoheishan to Heitosai.

In South Sakhalin, the 56th Rifle Corps launched a siege attack against Furuton. However, the fierce resistance of the 125th Regiment successfully repelled Soviet assaults for the next three days. On the same day, in preparation for an amphibious invasion of Toro, two naval patrol craft reconnoitered Esutoru. Additionally, Meretskov approved the Seishin Operation in North Korea, leading to another small naval force landing successfully at Chongjin that afternoon. Soon after, they faced a strong Japanese counterattack, which drove the landing force out of the port and inflicted heavy losses on the Russians. The following morning, a naval infantry battalion was landed to retake Chongjin, but Japanese reinforcements from the Nanam Divisional District Unit arrived to contest the port. As the Russians were pushed back again, Yumashev decided to embark the 13th Naval Infantry Brigade for a third assault scheduled for August 15. To the north, the 393rd Rifle Division advanced south along the coast, reaching Kwangjuryong by August 14. Concurrently, after breaking through the 128th Division’s main defenses at Lotzukou, the 25th Army reached Heitosai and prepared to launch its main attack against Murakami’s 3rd Army. The 5th Army struck the right flank of Shimizu’s 5th Army at Ssutaoling and in the hills southeast of Mutanchiang, while the 1st Red Banner Army attacked the northern and eastern flanks of the city and the railroad station at Yehho on the eastern bank of the Mutan River. The 35th Army began a rapid advance toward Poli and Linkou, encountering negligible opposition. Meanwhile, the 5th Rifle Corps reached Paoching, drove off its garrison, and continued marching toward Poli.

In addition, the 15th Army finally reduced the Hsingshanchen Fortified Region, opening a more direct advance route toward Chiamussu. Meanwhile, the 2nd Red Banner Army succeeded in breaking through the outer Japanese defenses to besiege the Sunwu Fortified Region and surround the Aihun Fortified Region. To the west, the 36th Army continued to encounter strong resistance at Hailar and Wunoerh. The 5th Guards Rifle Corps initiated a southeastward pursuit along the railroad toward Wangyemiao, eventually catching elements of the 107th Division at Tepossi, while also engaging Japanese units retreating from the Wuchakou area. The forward detachment of the 7th Guards Mechanized Corps occupied Taonan after a march hindered by wet weather and Japanese kamikaze attacks. The 17th Army captured Taopanshin, and Pliyev's left column overcame a small Manchurian cavalry force, entering Dolonnor at the east end of the pass across the southern Grand Khingan Mountains. Back in the Pacific, the Allies grew restless as they awaited a Japanese response, ultimately interpreting the silence as a non-acceptance of the imposed peace terms. Consequently, Truman ordered a resumption of attacks against Japan at maximum intensity. More than 400 B-29 bombers launched daylight attacks, while over 300 conducted night raids, culminating in what would become the largest and longest bombing raid of the Pacific War. Furthermore, Truman began planning to drop a third atomic bomb on Tokyo. However, before he could proceed, Emperor Hirohito met with the most senior Army and Navy officers in the early hours of August 14, convincing them to cooperate in ending the war.

The cabinet immediately convened and unanimously ratified the Emperor's wishes for an unconditional surrender. They also decided to destroy vast amounts of material related to war crimes and the war responsibilities of the nation's highest leaders. Shortly after concluding the conference, a group of senior army officers, including Anami, gathered in a nearby room and signed an agreement to execute the Emperor's order of surrender. This decision would significantly impede any attempts to incite a coup in Tokyo. During this meeting, General Kawabe Torashirō, Vice Chief of the Army General Staff, proposed that the senior officers present should each sign an agreement to carry out the Emperor's order of surrender, "The Army will act in accordance with the Imperial Decision to the last." An agreement was ultimately signed by each of the most important officers present, including Minister of War Anami, Chief of the Army General Staff Umezu, commander of the 1st General Army Field Marshal Sugiyama Hajime, commander of the 2nd General Army Field Marshal Hata Shunroku and Inspector-General of Military Training Doihara Kenji. When Umezu voiced concern about air units causing trouble, Vice Minister of War Wakamatsu Tadaichi took the agreement next door to the Air General Army headquarters, where its commander Kawabe Masakazu, the brother of Torashirō also signed. The document would serve to seriously impede any attempt to incite a coup in Tokyo.

Simultaneously, the Foreign Ministry transmitted orders to its embassies in Switzerland and Sweden to accept the Allied terms of surrender, which were received in Washington at 02:49 on August 14. Anticipating difficulties with senior commanders on distant war fronts, three princes of the Imperial Family, who held military commissions, were dispatched to deliver the news personally. By 19:00, the text of the Imperial Rescript on surrender was finalized, transcribed by the official court calligrapher, and presented to the cabinet for their signatures. Around 23:00, the Emperor, with assistance from an NHK recording crew, made a gramophone record of himself reading the rescript. At long last, Japan had admitted defeat.

However at around 21:30 on 14 August, the conspirators led by Hatanaka set their plan into motion. The Second Regiment of the First Imperial Guards had entered the palace grounds, doubling the strength of the battalion already stationed there, presumably to provide extra protection against Hatanaka's rebellion. But Hatanaka, along with Lt. Col. Shiizaki Jirō, convinced the commander of the 2nd Regiment of the First Imperial Guards, Colonel Haga Toyojirō, of their cause, by telling him (falsely) that Generals Anami and Umezu, and the commanders of the Eastern District Army and Imperial Guards Divisions were all in on the plan. Hatanaka also went to the office of Tanaka Shizuichi, commander of the Eastern region of the army, to try to persuade him to join the coup. Tanaka refused, and ordered Hatanaka to go home. Hatanaka ignored the order. Originally, Hatanaka hoped that simply occupying the palace and showing the beginnings of a rebellion would inspire the rest of the Army to rise up against the move to surrender. This notion guided him through much of the last days and hours and gave him the blind optimism to move ahead with the plan, despite having little support from his superiors. Having set all the pieces into position, Hatanaka and his co-conspirators decided that the Guard would take over the palace at 02:00. The hours until then were spent in continued attempts to convince their superiors in the Army to join the coup. Hatanaka, Shiizaki, Ida, and Captain Shigetarō Uehara (of the Air Force Academy) went to the office of Lt. Gen. Takeshi Mori to ask him to join the coup. Mori was in a meeting with his brother-in-law Michinori Shiraishi. The cooperation of Mori, who was the commander of the 1st Imperial Guards Division, was vital. When Mori refused to side with Hatanaka, Hatanaka killed him, fearing Mori would order the Guards to stop the rebellion. Uehara killed Shiraishi. These were the only two murders of the night. Hatanaka then used General Mori's official stamp to authorize Imperial Guards Division Strategic Order No. 584, a false set of orders created by his co-conspirators, which would greatly increase the strength of the forces occupying the Imperial Palace and Imperial Household Ministry, and "protecting" the Emperor.

The rebels, led by Hatanaka, spent the next several hours fruitlessly searching for the recordings of the surrender speech, failing to locate them amid a blackout caused by American bombings. Around the same time, another group of Hatanaka’s rebels, led by Captain Takeo Sasaki, targeted Prime Minister Suzuki's office with the intent to kill him. When they found it empty, they opened fire with machine guns, devastating the office, and then set the building ablaze before departing for Suzuki's home. Fortunately, Hisatsune Sakomizu, the chief secretary to Suzuki's Cabinet, had warned Suzuki, enabling him to escape just minutes before the assassins arrived. After setting fire to Suzuki's residence, the rebels then proceeded to the estate of Kiichirō Hiranuma, aiming to assassinate him as well. Hiranuma managed to escape through a side gate, but the rebels torched his house too. In the aftermath, Suzuki spent the remainder of August under police protection, sleeping in a different bed each night to avoid detection. Around 03:00, Hatanaka was informed that the Eastern District Army was on its way to the palace to confront him and urged him to surrender. As Hatanaka saw his plan collapse around him, he pleaded with Tatsuhiko Takashima, the Chief of Staff of the Eastern District Army, for airtime on NHK radio to explain his intentions to the Japanese people. His request was denied. Meanwhile, Colonel Haga, commander of the 2nd Regiment of the First Imperial Guards, learned that the Army did not support Hatanaka's rebellion and ordered him to vacate the palace grounds. Just before 05:00, while his rebels continued their search, Major Hatanaka went to the NHK studios, desperately trying to secure airtime to convey his actions. However, slightly over an hour later, after receiving a phone call from the Eastern District Army, Hatanaka finally conceded defeat. He gathered his officers and left the NHK studio, feeling the weight of his failed coup. At dawn, General Tanaka learned that the palace had been invaded, so he went there to confront the rebellious officers. He berated them for acting against the spirit of the Japanese army and ultimately convinced them to return to their barracks. By 08:00 on August 15, the rebellion was entirely dismantled. Although they had held the palace grounds for much of the night, they ultimately failed to find the recordings. After his failed coup, Hatanaka took his own life before witnessing Japan’s surrender.

While TF-38 refueled on August 14, Halsey signaled McCain, stating, “I intend to strike the same general target area on the fifteenth.” McCain informed TF-38, “Our orders to strike indicate the enemy may have dropped an unacceptable joker into the surrender terms. This war could last many months longer. We cannot afford to relax. Now is the time to pour it on.” In fact, the Western Allies had sunk their last Japanese ships of the war that day, when submarines USS Torsk (SS-423) and USS Spikefish (SS-404) torpedoed I-373 and two small escort ships in the East China Sea, resulting in the death of 112 Japanese sailors. The following morning, August 15, the Third Fleet launched its first strike of 103 aircraft at 04:15 hours. At 06:14, just as the first strike was returning and the second strike was five minutes from the target, Halsey was ordered by Nimitz, “Air attack will be suspended. Acknowledge.” Shortly afterward, an officer burst in, waving a transcript—President Truman’s official peace announcement. Halsey erupted with exuberance, “pounding the shoulders of everyone within reach.” He recalled, “My first thought at the great news was, ‘Victory!’ My second was, ‘God be thanked, I’ll never have to order another man out to die.’” However, within minutes, four retiring Hancock Hellcats were attacked by seven Japanese fighters, resulting in the Hellcats shooting down four without loss. Over Tokorazawa airfield, northwest of Tokyo, 20 IJAAF Ki-84 “Franks” ambushed six VF-88 Hellcats from Yorktown. The Hellcats managed to shoot down nine Franks but lost four of their own, along with their pilots. Rawlings’ dawn strikes were intercepted by about 12 Zeros. Escorting Seafires shot down eight Zeros but lost one, while an Avenger downed a ninth Zero. Tragically, seven TF-38 flyers never returned. During the morning, Halsey launched his last strike of the war, but was soon ordered by Admiral Nimitz to suspend all air attacks. At 12:00, the Emperor's recorded speech to the nation, reading the Imperial Rescript on the Termination of the War, was finally broadcast. The war was over… or was it really?

As Prime Minister Suzuki and his cabinet debated surrender, the Emperor Hirohito finally accepted the Potsdam Declaration, conditionally ensuring the imperial family's continuity. However, conspirators attempted a coup to prevent the surrender, ultimately failing. By August 15, Japan officially surrendered, marking the end of the Pacific War.
