Sobibor was a Nazi death camp run during the Second World War. It was located in Poland. On October 14, 1943, detainees at Sobibor successfully revolted. They killed 11 SS guards. About 300 of the 600 inmates escaped. Most were later found, and shot. About 50 survived until the end of the war. After the escape, the Nazis closed the camp and planted a forest, in an attempt to conceal what had taken place at Sobibor.
