Italian Monument at Leitenberg cemetery The bodies of 7,439 mostly unknown Dachau prisoners are buried in mass graves on a hill called Leitenberg, northwest of the camp. Starting on May 13, 1945, Dachau farmers were forced to haul the naked corpses, found in the camp by the American liberators on April 29, 1945, up to this hill for burial. The cemetery was first opened in October 1944 when the Nazis ran out of coal and could no longer cremate the bodies.
