During closing stages of the Soviet–Japanese War in August 1945, Japanese Kwantung Army still resisted with strong fortifications in Hutou Fortress. The Red Army with the cooperation of the fighters of local Chinese forces, took the fort on August 26, 1945. As the Hutou battle ended, Japan's unconditional surrender came 11 days later. Only 53 of the 1,400 Japanese soldiers survived one of the last campaigns of the Second World War. A Study on the Hutou Fortress Battle between Japan and the Soviet Union took place in 2009, by the Social Science Academy of Heilongjiang Province, entitled "The final battle of World War II".[2][3]
