Transport trains arrived at Westerbork every Tuesday from July 1942 to September 1944, and deported an estimated 97,776 Jews during the period. Jewish inmates were deported in waves to Auschwitz concentration camp (65 train-loads totaling 60,330 people), Sobibor (19 train-loads; 34,313 people), Theresienstadt ghetto, and Bergen-Belsen concentration camp (9 train-loads; 4,894 people). Almost all of the 94,643 persons deported to Auschwitz and Sobibor in German-occupied Poland were killed upon arrival.
