Chełmno extermination camp
While in Poznań, Damzog was actively involved in the mass expulsions of Poles from Reichsgau Wartheland to General Government, including after the 1941 German attack across the Soviet zone of occupation. He personally selected staff for the killing centre in Chełmno extermination camp and supervised its daily operation. The first victims there came from the local villages, and the mass killings with the use of gas vans started on 8 December 1941.
