1945 Soviet invasion of the Imperial Japanese puppet state of Manchukuo From Wikipedia, the free encyclopedia
The Soviet invasion of Manchuria, formally known as the Manchurian Strategic Offensive Operation[14] or simply the Manchurian Operation (Маньчжурская операция) and sometimes Operation August Storm,[1] began on 9 August 1945 with the Soviet invasion of the Japanese puppet state of Manchukuo, which was situated in Japanese-occupied Manchuria. It was the largest campaign of the 1945 Soviet–Japanese War, which resumed hostilities between the Union of Soviet Socialist Republics and the Empire of Japan after almost six years of peace.

Soviet gains on the continent were Manchukuo, Mengjiang (the northeast section of present-day Inner Mongolia) and northern Korea. The Soviet entry into this theater of the war and the defeat of the Kwantung Army were significant factors in the Japanese government's decision to surrender unconditionally, as it became apparent that the Soviet Union had no intention of acting as a third party in negotiating an end of the war on conditional terms.[1][2][15][16][17][18][19][20]
As agreed with the United Kingdom and the United States (Western Allies) at the Tehran Conference in November 1943 and the Yalta Conference in February 1945, the Soviet Union entered World War II's Pacific Theater within three months of the end of the war in Europe. The invasion began on 9 August 1945, exactly three months after the German surrender on May 8 (9 May, 0:43 Moscow time).
Although the commencement of the invasion fell between the American atomic bombing of Hiroshima, on 6 August, and only hours before the Nagasaki bombing on 9 August, the timing of the invasion had been planned well in advance and was determined by the timing of the agreements at Tehran and Yalta, the long-term buildup of Soviet forces in the Far East since Tehran, and the date of the German surrender some three months earlier; on August 3, Marshal Vasilevsky reported to Premier Joseph Stalin that, if necessary, he could attack on the morning of 5 August.
At 11 p.m. Trans-Baikal (UTC+10) time on 8 August 1945, Soviet foreign minister Vyacheslav Molotov informed Japanese ambassador Naotake Satō that the Soviet Union had declared war on Japan, and that from 9 August the Soviet government would consider itself to be at war with Japan.[21] At one minute past midnight Trans-Baikal time on 9 August 1945, the Soviets commenced their invasion simultaneously on three fronts to the east, west and north of Manchuria:
Though the battle extended beyond the borders traditionally known as Manchuria—that is, the traditional lands of the Manchus—the coordinated and integrated invasions of Japan's northern territories has also been called the Battle of Manchuria.[22] It has also been referred to as the Manchurian strategic offensive operation.[23]
The Russo-Japanese War of the early 20th century resulted in a Japanese victory and the Treaty of Portsmouth by which, in conjunction with other later events including the Mukden incident and Japanese invasion of Manchuria in September 1931, Japan eventually gained control of Korea, Manchuria and South Sakhalin. In the late 1930s there were a number of Soviet-Japanese border incidents, the most significant being the Battle of Lake Khasan (Changkufeng Incident, July–August 1938) and the Battle of Khalkhin Gol (Nomonhan Incident, May–September 1939), which led to the Soviet–Japanese Neutrality Pact[24][25] of April 1941. The Neutrality Pact freed up forces from the border incidents and enabled the Soviets to concentrate on their war with Germany, and the Japanese to concentrate on their southern expansion into Asia and the Pacific Ocean.
With success at Stalingrad, and the eventual defeat of Germany becoming increasingly certain, the Soviet attitude to Japan changed, both publicly, with Stalin making speeches denouncing Japan, and covertly with the building up of forces and supplies in the Far East. At the Tehran Conference in November 1943, Stalin, Winston Churchill, and Franklin Roosevelt agreed that the Soviet Union would enter the war against Japan once Germany was defeated. Stalin faced a dilemma: he wanted to avoid a war on two fronts at almost any cost, yet he also saw an opportunity to secure gains in the Far East on top of those he expected in Europe. The only way Stalin could ensure these gains without a two-front war would be for Germany to capitulate before Japan.
Due to the Soviet–Japanese Neutrality Pact, the Soviets made it official policy to intern Allied aircraft and crews who landed in Soviet territory following operations against Japan. However, the Soviets and Western Allies soon came to informal arrangements to circumvent official policy. Under the auspices of Lend Lease, the Allies officially transferred aircraft of the same types interred by the Soviets in the Far East, the mutual understanding being that the Soviets would also be able use "interned" Allied aircraft against the Germans without revealing their true origins. In return, Allied airmen held in the Soviet Union were usually transferred to camps near Iran or other Allied-controlled territory, from where they were typically allowed to "escape" after some period of time.[26] Nevertheless, the Soviet buildup in the Far East steadily accelerated even before the defeat of Germany. By early 1945 it had become apparent to the Japanese that the Soviets were preparing to invade Manchuria, though they correctly calculated that they were unlikely to attack prior to Germany's defeat. In addition to their problems in the Pacific, the Japanese realised the need to determine when and where a Soviet invasion would occur.
At the Yalta Conference in February 1945, Stalin secured Roosevelt's acceptance of Soviet expansion in the Far East, in return for agreeing to enter the Pacific war within two or three months after the defeat of Germany. By the middle of March, things were not going well in the Pacific for the Japanese, and they had withdrawn their elite troops from Manchuria to support actions in the Pacific. Meanwhile, the Soviets continued their Far Eastern buildup, having decided that they did not wish to renew the Neutrality Pact. The terms of the Pact required a notification of expiry 12 months ahead of time, so on 5 April 1945 the Soviets ostensibly obliged, informing the Japanese that they did not wish to renew the treaty.[27] This caused the Japanese considerable concern,[28][29] but the Soviets went to great efforts to assure the Japanese that the treaty would still be in force for another twelve months, and that the Japanese had nothing to worry about.[30]
Germany surrendered just after midnight Moscow time on 9 May 1945, meaning that if the Soviets were to honour the agreement at Yalta, they would need to enter the war with Japan by 9 August. The situation continued to deteriorate for the Japanese, now the only Axis power left in the war. They were keen to stay at peace with the Soviets,[30] and ultimately to achieve an end to the war. Since Yalta, they had repeatedly tried to convince the Soviets to extend the Neutrality Pact, as well as attempting to enlist them to mediate peace negotiations with the Western Allies. The Soviets did nothing to discourage these overtures, instead happy to draw out the process for as long as possible whilst continuing to prepare their invasion forces.[30] One of the goals of Admiral Baron Suzuki's cabinet upon taking office in April was to try to secure any peace terms whatsoever short of unconditional surrender.[31] In late June, they once again approached the Soviets, inviting them to mediate with the Western Allies in support of Japan, providing them with specific proposals. In exchange, they were prepared to offer the Soviets very attractive territorial concessions. Stalin ostensibly expressed interest, and the Japanese now awaited an official Soviet response, even as the Soviets continued to deliberately avoid providing one. The Potsdam Conference was held from 16 July to 2 August; on 24 July the Soviet Union recalled all its embassy staff and families from Japan. On 26 July the conference produced the Potsdam Declaration whereby Churchill, Harry S. Truman and Chiang Kai-shek demanded Japan's unconditional surrender. The Japanese avoided responding to the declaration, instead continuing to wait on a clarifying Soviet reply.[30]
The Japanese had been monitoring Trans-Siberian Railway traffic and Soviet activity to the east of Manchuria. In conjunction with the delaying tactics, this suggested that the Soviets would not be ready to invade east Manchuria before the end of August. The Japanese did not have any concrete evidence as to when or where any invasion would occur.[16] They had estimated that an attack was not likely before the spring of 1946, but the Stavka had in fact been planning for a mid-August offensive, successfully concealing the buildup of a force of 90 divisions. Many Soviet units had crossed Siberia in their vehicles to avoid straining the rail link.[32]
The Japanese were caught completely by surprise upon receiving the Soviet declaration of war an hour before midnight on 8 August, now facing a simultaneous invasion on three fronts that began just after midnight on 9 August.
The Far East Command,[2] under Marshal of the Soviet Union Aleksandr Vasilevsky, had a plan to conquer Manchuria that was simple but huge in scale,[1] calling for a massive pincer movement over all of Manchuria. This was to be performed by the Transbaikal Front from the west and by the 1st Far Eastern Front from the east; the 2nd Far Eastern Front was to attack the center of the pocket from the north.[2] The only Soviet equivalent of a theater command that operated during the war (apart from the short-lived 1941 "Directions" in the west), Far East Command, consisted of three Red Army fronts.
The Transbaikal Front, under Marshal Rodion Malinovsky, included:[1]
The Transbaikal Front was to form the western half of the Soviet pincer movement, attacking across the Inner Mongolian desert and over the Greater Khingan mountains.[2] These forces had as their objectives firstly to secure Mukden (present day Shenyang), then to meet troops of the 1st Far Eastern Front at the Changchun area in south central Manchuria,[1] and in doing so finish the pincer movement.[1]
Amassing over one thousand tanks and self-propelled guns, the 6th Guards Tank Army was to serve as an armored spearhead, leading the Front's advance and capturing objectives 350 km (220 mi) inside Manchuria by the fifth day of the invasion.[1]
The 36th Army was also attacking from the west, but with the objective of meeting forces of the 2nd Far Eastern Front at Harbin and Qiqihar.[2]
The 1st Far Eastern Front, under Marshal Kirill Meretskov, included:[1]
The 1st Far Eastern Front was to form the eastern half of the pincer movement. This attack involved the 1st Red Banner Army, the 5th Army and the 10th Mechanized Corps striking towards Mudanjiang (or Mutanchiang).[1] Once that city was captured, this force was to advance towards the cities of Jilin (or Kirin), Changchun and Harbin.[1] Its final objective was to link up with the forces of the Transbaikal Front at Changchun and Jilin thus closing the double envelopment movement.
As a secondary objective, the 1st Far Eastern Front was to prevent Japanese forces from escaping to Korea, and then invade the Korean Peninsula up to the 38th parallel,[1] establishing in the process what later became North Korea. This secondary objective was to be carried out by the 25th Army.[1] Meanwhile, the 35th Army was tasked with capturing the cities of Boli (or Poli), Linkou and Mishan.[1]
The 2nd Far Eastern Front, under General Maksim Purkayev, included:[1]
The 2nd Far Eastern Front was deployed in a supporting attack role.[1] Its objectives were the cities of Harbin and Qiqihar,[2] and to prevent an orderly withdrawal to the south by the Japanese forces.[1] The front also included the 88th Separate Rifle Brigade, composed of Chinese and Korean guerrillas of the Northeast Anti-Japanese United Army who had retreated into the USSR in the beginning of the 1940s. The unit, led by Zhou Baozhong, was set to participate in the invasion for use in sabotage and reconnaissance missions, but was considered too valuable to be sent into the battlefield. They were thus withheld from participating in combat and instead used for leadership and administrative positions for district offices and police stations in the liberated areas during the subsequent occupation.[33] The Korean battalion of the brigade (including future leader of the DPRK, Kim Il Sung) were also sent to assist in the following occupation of Northern Korea as part of the 1st Far Eastern Front.[33]
Once troops from the 1st Far Eastern Front and Transbaikal Front captured the city of Changchun, the 2nd Far Eastern Front was to attack the Liaotung Peninsula and seize Port Arthur (present day Lüshun).[1]
Each front had "front units" attached directly to the front instead of an army.[1] The forces totaled 89 divisions with 1.5 million men, 3,704 tanks, 1,852 self propelled guns, 85,819 vehicles and 3,721 aircraft. Approximately one-third of its strength was in combat support and services.[1] The Soviet plan incorporated all of the experience in maneuver warfare that they had acquired in fighting the Germans.[1]
The Kwantung Army of the Imperial Japanese Army, under General Otozo Yamada, was the major part of the Japanese occupation forces in Manchuria and Korea, and consisted of two Area Armies and three independent armies:[1]
Each Area Army (Homen Gun, the equivalent of a Western "army") had headquarters units and units attached directly to the Area Army, in addition to the field armies (the equivalent of a Western corps). In addition, the Japanese were assisted by the forces of their puppet states of Manchukuo and Mengjiang. Manchukuo had an army of about 170,000 to 200,000 troops, while Mengjiang had around 44,000 troops, with the majority of these puppet troops being of dubious quality.[citation needed] Korea, the next target for the Soviet Far East Command, was garrisoned by the Japanese Seventeenth Area Army.[citation needed]
Including the Japanese forces in Korea, the Kwantung Army had over 900,000 men in 31 divisions and 13 brigades; there were about 400 obsolescent tanks and 2,000 aircraft (of the 1040 aircraft in Manchuria, only 230 were combat types and 55 were modern[34]).[35] However, the Kwantung Army was far below its authorized strength; most of its heavy equipment and all of its best military units had transferred to the Pacific Theater over the previous three years to contend with the advance of American forces. Some Kwantung Army units had also re-deployed south against the Nationalist Chinese in Operation Ichigo in 1944. By 1945 the Kwantung Army contained a large number of raw recruits and conscripts, with generally obsolete, light, or otherwise limited equipment. Almost all of the tanks were early 1930s models such as the Type 95 Ha-Go and Type 89 I-Go, the anti-tank units only possessed Type 1 37 mm anti-tank guns that were ineffective against Soviet armor, and the infantry had very few machine-guns and no anti-materiel rifles or submachine guns. As a result, the Japanese forces in Manchuria and Korea had essentially been reduced to a light-infantry counter-insurgency force with limited mobility and limited ability to fight a conventional land war against a coordinated enemy. In fact, only six of the Kwantung Army's divisions existed prior to January 1945. Accordingly, the Japanese regarded none of the Kwantung Army's units as combat ready, with some units being declared less than 15% ready.[36]
The Imperial Japanese Navy did not contribute to the defense of Manchuria, the occupation of which it had always opposed on strategic grounds. Additionally, by the time of the Soviet invasion, the few remnants of its fleet were stationed and tasked for the defense of the Japanese home islands in the event of an invasion by American forces.
Compounding their problems, the Japanese military made many wrong assumptions and major mistakes, most significantly:
Due to the withdrawal of the Kwantung Army's elite forces for redeployment into the Pacific Theater, the Japanese made new operational plans during the summer of 1945 for the defence of Manchuria against a seemingly inevitable Soviet attack. These called for redeploying the bulk of available forces from the border areas; the borders were to be held lightly and delaying actions were to be fought while the main force was to hold the southeastern corner in strength (so defending Korea from attack).[15]
Further, the Japanese had observed Soviet activity only on the Trans-Siberian railway and along the east Manchurian front, and accordingly prepared for an invasion from the east. They believed that when an attack occurred from the west, the redeployed forces would be able to deal with it.[15][16]
Although the Japanese redeployment in Manchukuo had begun, it was not due for completion until September 1945, and hence the Kwantung Army was in the midst of redeploying when the Soviets launched their attack simultaneously on all three fronts.
The operation was carried out as a classic double pincer movement over an area the size of the entire Western European theatre of World War II. In the western pincer, the Red Army advanced over the deserts and mountains from Mongolia, far from their resupply railways. This confounded the Japanese military analysis of Soviet logistics, and the defenders were caught by surprise in unfortified positions. The Kwantung Army commanders were engaged in a planning exercise at the time of the invasion, and were away from their forces for the first eighteen hours of conflict.
The Russians treated the Japanese with the utmost cruelty after their deadly attack on Japan's Kwantung Army in Manchuria just days before Japan's surrender.[37] Japanese forces were overwhelmed by Soviet attacks. Soviet paratroopers destroyed the Kwantung Army from behind its own lines, while Japanese anti-tank shells bounced off the sides of Soviet tanks.[38] The Japanese forces in Manchuria retreated in fear.[39]
Japanese troops and able-bodied Japanese men in Manchuria were taken prisoner by the Russians and transported to labor camps in Siberia, where many Japanese men would die.[40] From the Russians' perspective, this was seen as revenge for Russia's defeat in the Russo-Japanese War of 1905.[41] The stories of how poorly the Soviets treated the Japanese were brought to Beijing by Japanese evacuees of Manchuria, creating panic among the Japanese population; however, the Russians honored their agreement with Chiang Kai-shek by not entering China proper.[42]
Japanese communication infrastructure was poor, and the Japanese lost communication with forward units very early on. However, the Kwantung Army had a formidable reputation as fierce and relentless fighters, and even though understrength and unprepared, put up strong resistance at the town of Hailar which tied down some of the Soviet forces. The Japanese defenders held out until 18 August, when 3,827 survivors surrendered.[43] At the same time, Soviet airborne units seized airfields and city centers in advance of the land forces, and aircraft ferried fuel to those units that had outrun their supply lines.
Due to Japanese 37mm and 47mm anti-tank guns being only suitable for fighting light Soviet tanks, Japanese forces decided to use suicide bomber squads strapped with grenades and explosives as their main improvised anti-tank weapon.[44][45]
Japanese Army aviation employed several kamikaze attacks to strike Soviet armoured targets and fortifications in attempt to stop the Soviet advance.[46][47][48][49]
Nevertheless, the prospect of a quick defeat to the Japanese Army seemed far from clear. Given the fanatical and sometimes suicidal resistance put up by the Japanese forces similar in April–June 1945 Battle of Okinawa, there was every reason to believe that a long, difficult campaign for the capture of the last remaining Japanese fortified areas was expected. In some parts of the Soviet offensive these expectations were fulfilled.[50]
The Soviet pincer from the East crossed the Ussuri and advanced around Khanka Lake and attacked towards Suifenhe, and although Japanese defenders fought hard and provided strong resistance, the Soviets proved overwhelming.
After a week of fighting, during which time Soviet forces had penetrated deep into Manchukuo, Japan's Emperor Hirohito recorded the Gyokuon-hōsō which was broadcast on radio to the Japanese nation on 15 August 1945. It made no direct reference to a surrender of Japan, instead stating that the government had been instructed to accept the terms of the Potsdam Declaration fully. This created confusion in the minds of many listeners who were not sure if Japan had surrendered. The poor audio quality of the radio broadcast, as well as the formal courtly language in which the speech was composed, worsened the confusion.
The Imperial Japanese Army Headquarters did not immediately communicate the cease-fire order to the Kwantung Army, and many elements of the army either did not understand it, or ignored it. Hence, pockets of fierce resistance from the Kwantung Army continued, and the Soviets continued their advance, largely avoiding the pockets of resistance, reaching Mukden, Changchun and Qiqihar by 20 August. The cease-fire order was eventually communicated to the Kwantung Army, but not before the Soviets had made most of their territorial gains.
On the Soviet right flank, the Soviet-Mongolian Cavalry-Mechanized Group entered Inner Mongolia and quickly took Dolon Nur and Kalgan. The Emperor of Manchukuo (and former Emperor of China), Puyi, was captured by the Red Army.
On August 18, several Soviet amphibious landings were conducted ahead of the land advance: three landings in northern Korea, one landing in South Sakhalin, and one landing in the Kuril Islands. This meant that, in Korea at least, there were already Soviet soldiers waiting for the troops coming overland. In South Sakhalin and the Kurils, it meant a sudden establishment of Soviet sovereignty.
The land advance was stopped a good distance short of the Yalu River, the start of the Korean Peninsula, when even aerial supply became unavailable. The forces already in Korea were able to establish control in the peninsula's northern area. In accordance with arrangements made earlier with the American government to divide the Korean Peninsula, Soviet forces stopped at the 38th parallel, leaving the Japanese still in control of the southern part of the peninsula. Later, on 8 September 1945, American forces landed at Incheon.
The invasion of Manchuria was a factor that contributed to the surrender of Japan and the end of World War II. In addition, the Soviet occupation of Manchuria, along with the northern portions of the Korean Peninsula, allowed for parts of those regions to be transferred by the Soviet Union into the control of local communists after the Soviet withdrawal in 1946[51] in spite of a 1945 agreement signed between the Soviets and the Kuomintang.[52] The control of these regions by communist governments backed by Soviet authorities would be a factor in the rise of the Chinese Communists and shape the political conflict of the Korean War.
Several thousand Japanese who were sent as colonizers to Manchukuo and Inner Mongolia were left behind in China. The majority of Japanese left behind in China were women, and these Japanese women mostly married Chinese men and became known as "stranded war wives" (zanryu fujin).[53][54] Because they had children fathered by Chinese men, Japanese women were not allowed to bring their Chinese families back with them to Japan, so most of them stayed. Japanese nationality laws allowed only children fathered by Japanese fathers to become Japanese citizens.
In late 1949, numerous members of the former Kwantung Army who had been captured in the Soviet invasion of Manchuria were convicted in connection with the activities of Unit 731, and related units for their connections with crimes against humanity and the use of chemical and biological weapons.[55]
During the invasion of Manchuria, Soviet soldiers killed and raped Japanese civilians.[56] The most famous example was the Gegenmiao massacre, Soviet soldiers from an armoured unit massacred over one thousand Japanese women and children.[57] Property of the Japanese were also looted by the Soviet troops.[56] Soviet forces responsible for the massacre had carried out the same crimes against civilians in East Prussia.[57]
According to Soviet historian Vyacheslav Zimonin, many Japanese settlers committed mass suicide as the Red Army approached. Mothers were forced by the Japanese military to kill their own children before being killed themselves.[58] The Japanese army often took part in the killings of its civilians. The commander of the 5th Japanese Army, General Shimizu, commented that "each nation lives and dies by its own laws." Wounded Japanese soldiers who were incapable of moving on their own were often left to die as the army retreated.[58]
British and U.S. reports indicate that the Soviet troops that occupied Manchuria (about 700,000) also looted and terrorized the local people of Mukden and were not discouraged by Soviet authorities from "three days of rape and pillage." In Harbin, Soviet forces ignored protests from Chinese Communist Party leaders on the mass rape and looting.[59][60][61][62][63][64] There were several incidents in which Chinese police forces in Manchuria arrested or even killed Soviet troops for committing various crimes, leading to some conflicts between the Soviet and Chinese authorities in Manchuria.[65]
During the Soviet occupation of North Korea, it was reported that Soviet soldiers committed rape against both Japanese and Korean women alike in the northern half of the Korean peninsula.[66][67] Soviet soldiers also looted the property of both Japanese and Koreans living in northern Korea.[68] The Soviets laid claim to Japanese enterprises in Manchuria and northern Korea and took valuable materials and industrial equipment.[59][68]
Konstantin Asmolov of the Center for Korean Research of the Russian Academy of Sciences dismisses Western accounts of Soviet violence against civilians in the Far East as exaggeration and rumor and contends that accusations of mass crimes by the Red Army inappropriately extrapolate isolated incidents regarding the nearly 2,000,000 Soviet troops in the Far East into mass crimes. According to him, such accusations are refuted by the documents of the time, from which it is clear that such crimes were far less of a problem than in Germany. Asmolov further asserts that the Soviets prosecuted their perpetrators while prosecution of German and Japanese "rapists and looters" in WWII was virtually unknown.[69]
Japanese women in Manchukuo were repeatedly raped by Russian soldiers every day including underage girls from the families of Japanese who worked for the military and the Manchukuo rail at Beian airport and Japanese military nurses. The Russians seized Japanese civilian girls at Beian airport where there were a total of 1,000 Japanese civilians, repeatedly raping 10 girls each day as recalled by Yoshida Reiko and repeatedly raped 75 Japanese nurses at the Sunwu military hospital in Manchukuo during the occupation. The Russians rejected all the pleading by the Japanese officers to stop the rapes. The Japanese were told by the Russians that they had to give their women for rape as war spoils.[70][71][72][73][74][75]
Soviet soldiers raped Japanese women from a group of Japanese families that were with Yamada Tami that attempted to flee their settlements in 14 August and go to Mudanjiang. Another group of Japanese women that were with Ikeda Hiroko that on 15 August tried to flee to Harbin but returned to their settlements were raped by Soviet soldiers.[76]
