 After the gassings, the "Sonderkommando" removed the corpses from the gas chambers, then extracted any gold teeth.Initially, the victims were buried in mass graves, but were later cremated during "Sonderaktion 1005" in all camps of Operation Reinhard.The "Sonderkommando" were responsible for burning the corpses in the pits, stoking the fires, draining surplus body fat and turning over the "mountain of burning corpses ... so that the draught might fan the flames" wrote Commandant Höss in his memoir while in the Polish custody.
