"I estimate that the number of Jews gassed at Sobibor was about 350,000. In the canteen at Sobibor I once overheard a conversation between Frenzel, Stangl and Wagner. They were discussing the number of victims in the extermination camps of Belzec, Treblinka and Sobibor and expressed their regret that Sobibor "came last" in the competition."

“I was blamed for being responsible for the death of the Jewish girls Ruth and Gisela, who lived in the so-called forester house. As it is known, these two girls lived in the forester house, and they were visited frequently by the SS men. Orgies were conducted there. They were attended by Kurt Bolender, Gomerski, Karl Ludwig, Franz Stangl, Gustav Wagner, and Steubel. I lived in the room above them and due to these celebrations could not fall asleep after coming back from a journey....”

“I cannot exclude any member of the Sobibor camp staff of taking part in the extermination operation. We were a "blood brotherhood gang" in a foreign land. We were a band of "fellow conspirators" in a foreign land, surrounded by Ukrainian volunteers whom we could not trust....The bond between us was so strong that Frenzel, Stangl and Wagner had had a ring with SS runes made from five-mark pieces for every member of the permanent staff. These rings were distributed to the camp staff as a sign so that the "conspirators" could be identified. In addition the tasks in the camp were shared. Each of us had at some point carried out every camp duty in Sobibor .”

“Usually the undressing went smoothly. Subsequently, the Jews were taken through the "tube" to Camp III – the real extermination camp. The transfer through the "tube" proceeded as follows: one SS man was in the lead and five or six Ukrainian auxiliaries were at the back hastening the along. The women were taken through a barrack where their hair was cut off. In Camp III the Jews were received by SS men.... As I already mentioned, the motor was then switched on by Goringer and one of the auxiliaries whose name I don't remember. Then the gassed Jews were taken out.”
