In total, 139,667 people were sent there over three-and-a-half years; of these, 16,832 were alive at the end of the war. About half of the survivors were sent in October 1944. During the camp’s operation, 63 transports, starting in October 1942, carried prisoners to the concentration and extermination camps in Poland. Others succumbed to disease and violence, and were burned in the crematorium built by prison labor and located outside the city walls.
