Chaim Engel was an inmate of the Sobibór Camp. In a deposition of 19 July 1946, he claimed that the gas was fed into the gas chambers through showerheads, and that, after the murder, the floors opened, and the bodies were discharged into a space below. He claimed a total of some 800,000 victims for the camp.
His claims are rejected as false by the orthodoxy, who insists that the gas was fed through pipes rather than showerheads. These chambers did not have collapsible floors either. The corpses were instead taken out of the chamber manually, sideways through a normal door. Furthermore, only about a quarter million victims are said to have died in the camp.
