Soviet invasion of Manchuria

Soviet invasion of Manchuria. The Soviet Union, led by Joseph Stalin, launched a massive invasion of Manchuria, a region of Northeast China, in August 1945, as part of its declaration of war against Imperial Japan. This operation, also known as Operation August Storm, involved the Soviet Army, including the Transbaikal Front and the 1st Far Eastern Front, and was supported by the Mongolian People's Army. The invasion was a key factor in the Allied victory in World War II, and it led to the Japanese surrender and the occupation of Japan by the Allied Powers, including the United States, the United Kingdom, and the Soviet Union.

Background

The Soviet Union had been negotiating with the United States and the United Kingdom at the Yalta Conference and the Potsdam Conference regarding its potential entry into the war against Imperial Japan. The Soviet Union had been bound by the Soviet–Japanese Neutrality Pact since 1941, but it had been making preparations for an invasion of Manchuria since 1944, with the Soviet General Staff and the Stavka planning the operation. The Soviet Union saw an opportunity to gain control of Manchuria and other territories in Northeast Asia, including Korea and Sakhalin Island, and to limit the influence of the United States and the United Kingdom in the region. The Soviet Union also sought to avenge its defeat in the Russo-Japanese War and to gain access to the Pacific Ocean and the Sea of Japan.

The Invasion

The invasion of Manchuria began on August 8, 1945, with a massive artillery barrage by the Soviet Army against the Imperial Japanese Army and the Manchukuo National Army. The Soviet Air Forces provided air support, with Tupolev Tu-2 and Petlyakov Pe-2 bombers attacking Japanese airfields and troop concentrations. The Soviet Navy also played a key role, with the Pacific Fleet and the Amur Flotilla providing naval gunfire support and transporting troops and supplies. The Mongolian People's Army also participated in the invasion, with its Mongolian Cavalry Corps advancing into Inner Mongolia and linking up with the Soviet Army. The Chinese Communist Party and the Chinese Nationalist Party also supported the Soviet Union in its invasion of Manchuria, with the Chinese Red Army and the National Revolutionary Army fighting against the Imperial Japanese Army.

Major Operations

The Soviet Army launched several major operations during the invasion of Manchuria, including the Khingan–Mukden Operation and the Harbin–Girin Operation. The Soviet Army also advanced into Korea and Sakhalin Island, with the 25th Army and the 16th Army capturing the cities of Seoul and Yuzhno-Sakhalinsk. The Soviet Navy also launched several amphibious assaults, including the Invasion of South Sakhalin and the Invasion of the Kuril Islands. The Soviet Air Forces provided close air support to the Soviet Army and the Mongolian People's Army, with Ilyushin Il-2 and Yakovlev Yak-3 aircraft attacking Japanese troop concentrations and airfields. The Soviet Union also used partisans and guerrilla warfare to disrupt Japanese supply lines and communication networks.

Aftermath

The invasion of Manchuria ended with the Japanese surrender on September 2, 1945, and the occupation of Japan by the Allied Powers. The Soviet Union gained control of Manchuria and other territories in Northeast Asia, including Korea and Sakhalin Island. The Soviet Union also established a puppet state in Manchuria, with the Northeast Democratic Federation and the Northeast People's Government being established. The Chinese Communist Party and the Chinese Nationalist Party also gained control of China, with the Chinese Civil War breaking out in 1946. The Soviet Union and the United States also established a division of Korea along the 38th parallel, with the Soviet Union controlling the north and the United States controlling the south.
