On July 26, 1944, the Soviet sponsored Polish Committee of National Liberation gave NKVD agents their remit in the Polish territories. Then, on September 11, 1944, Soviet forces took the town of Rembertów. The Soviet troops reopened the Rembertów prisoner of war camp in order to detain Polish and German prisoners as well as former Russian detainees, who were assumed to have collaborated with the Nazis. Over time, the Polish detainees included soldiers of the Home Army as well as those of other resistance organizations such as the Narodowe Siły Zbrojne (NSZ, the national army force) and the Bataliony Chłopskie (BCh, the peasant battalions). Rembertów camp also became a mustering point for Polish anticommunists being sent to Siberia. Russian troops tried to hide this from the local Polish townsfolk by ordering the prisoners in a broken German.
