He then temporarily transferred to Mittelbau-Dora concentration camp, but returned to Auschwitz in May 1944. Initially he commanded the guard company at Auschwitz main camp, then later the one at Monowitz concentration camp from August to October 1944. During his time at Auschwitz, Kollmer participated in the extermination of Jews in the Birkenau gas chambers, and carried out executions against the shooting wall between blocks 10 and 11 and at the Buna factory.
