On 1 February 1942 he was transferred to Auschwitz concentration camp and was appointed as head of Department III, and named Schutzhaftlagerführer at Auschwitz I, where he remained until 16 August 1943. It was during this time at Auschwitz that Aumeier made a name for himself, responsible for many draconian methods, including torture, beatings, and executions. On 19 March 1942, 144 women were shot at the execution wall in the courtyard of Blocks 10 and 11 on Aumeier’s orders.
