At the Treblinka extermination camp, work begins to unearth the more than 700,000 corpses which had been buried there. Heinrich Himmler had visited Treblinka earlier in the month and wasn't happy that they had been burying the dead instead of cremating them as he had previously ordered.
So exhuming and then cremating corpses would become the primary task at Treblinka during the coming months. The Nazis use large, open-air incinerators to burn as many as 1,000 bodies at a time. It takes around five hours for each group and the incinerators run 24 hours a day.
