The Gegenmiao massacre, also known as the Gegenmiao incident, was a massacre conducted by the Soviet Army against over half of a group of 1,800 Japanese women and children who had taken refuge in the lamasery Gegenmiao/Koken-miao (葛根廟) on August 14, 1945 during the Soviet invasion of Manchuria.
It happened in Gegenmiao/Koken-miao (present day: Gegenmiao zhen; 葛根廟鎭), a town in the Horqin Right Front Banner of the Hinggan League of Inner Mongolia. Refugees were shot, run over by tanks or trucks, and bayoneted by the Soviet Army after they raised a white flag. After two hours, well over one thousand Japanese, mostly women and children, had been killed. The Chinese also attacked them, and some Japanese were chased into a river, where they drowned. Some women were stripped and raped by soldiers. A woman was stripped and killed by the Chinese after her child was killed by the Soviet Army. They also beat mothers into submission in order to steal children. In the market a Japanese boy could sell for 300 yen, a girl for 500 yen.
