Following the large numbers of Soviet prisoners-of-war captured during the Battle of Kiev, the projected capacity was subsequently increased to 50,000 and construction for that many began on October 1, 1941 (as it did also in Auschwitz-Birkenau, which had received the same order). In early November, the plans were extended to allow for 125,000 inmates and in December to 150,000.[1] It was further increased in March 1942 to allow for 250,000 Soviet prisoners of war.
