In February 1944, a satellite camp to Auschwitz was set up in Günthergrube (polish Ledziny). The prisoners were used as slave workers in an existing coal mine and the expansion of coal mines. The prisoners were housed in inadequate barracks. The majority of the prisoners were Jews from France, Holland, Poland and Hungary. Initially there were about 300 prisoners in the camp, but during the summer the number of prisoners doubled. Between February and May, more than 100 prisoners who were too sick were sent to work back to Auschwitz. Almost twenty prisoners died in the camp itself. When the camp was evacuated in January 1945, about 600 prisoners were forced to march toward Gliwice.
