The camp, which operated from October 1, 1941, until July 22, 1944, was captured nearly intact, because the rapid advance of the Soviet Red Army during "Operation Bagration" prevented the "SS" from destroying most of its infrastructure, and the inept Deputy Camp Commandant Anton Thernes failed in his task of removing incriminating evidence of war crimes.
