 The mass deportation of Jews from the Warsaw Ghetto began on 22 July 1942 with the first shipment of 6,000 people. The gas chambers started operation the following morning. For the next two months, deportations from Warsaw continued on a daily basis via two shuttle trains (the second one, from 6 August 1942), each carrying about 4,000 to 7,000 people crying for water. No other trains were allowed to stop at the Treblinka station. The first daily trains came in the early morning, often after an overnight wait, and the second, in mid-afternoon. All new arrivals were sent immediately to the undressing area by the Sonderkommando squad that managed the arrival platform, and from there to the gas chambers. According to German records, including the official report by SS Brigadeführer Jürgen Stroop, 265,000 Jews were transported in freight trains from the Warsaw Ghetto to Treblinka during the period from 22 July to 12 September 1942.
