Vernichtungslager Sobibor
The Sobibór extermination camp, disguised as a railway transit camp not far from Lublin, began mass gassing operations in May 1942. As in other extermination centers, the Jews, taken off the Holocaust trains arriving from liquidated ghettos and transit camps (Izbica, Końskowola) were met by an SS-man dressed in a medical coat. "Oberscharführer" Hermann Michel gave the command for prisoners' "disinfection".
