The first group of people arrived in the camp from Antwerp on 27 July 1942. Between August and December 1942, two transports, each with about 1,000 Jews, left the camp every week for Auschwitz concentration camp. Between 4 August 1942 and 31 July 1944, a total of 28 trains left Mechelen for Poland, carrying 24,916 Jews and 351 Roma; most of them went to Auschwitz. This figure represented more than half of the Belgian Jews murdered during the Holocaust. In line with the Nazi racial policy that much later became named the "Porajmos" (or "Samudaripen"), 351 Belgian Roma were sent to Auschwitz in early 1944.
