Departures of note

Siegfried Graetschus joined the SS in 1935 and the Nazi Party in 1936. He served at Bernburg Euthanasia Centre and Treblinka extermination camp before being posted to Sobibor in August 1942, where he succeeded Erich Lachmann as commander of about 200 Ukrainian Trawniki guards and was noted for his brutality.

At the very beginning of his tenure, Siegfried Graetschus transformed a confiscated post car into a mobile gas chamber. He used the vehicle to murder people with disabilities and the mentally ill who were searched for in nearby villages, after which the use of the car was discontinued in favor of stationary gas chambers.
