Auschwitz was a cluster of camps. Some were slave labor camps with slaves from many different backgrounds worked, and where many were worked to death. Auschwitz II Birkenau was a death camp, devoted almost entirely to the slaughter of Jews.
65,000 Jews were killed.

His actions, along with those of other Soviet forces, contributed to the broader liberation of concentration camps across Europe towards the end of World War II.
