Winer described the entire extermination procedure at the camp, how people were murdered in gas vans, how their corpses were removed by the forest commando, how the inside of the vans was cleaned between loads, and how the bodies were buried in large mass graves.[4] Winer wrote:
Winer also described the brutal treatment of Sonderkommando prisoners, left alive to dispose of the corpses, and his escape from the camp.[5] Oneg Shabbat group and Winer then copied the report in both Polish and German; they sent the Polish version to the Polish Underground State, while the German copy was meant for the German people, in the hope it would evoke their compassion for the Jews.[6][7][8] It is unclear what was done with the reports at that point.
Winer subsequently escaped to Zamość where he wrote to the Warsaw Ghetto of the existence of a death camp in Bełżec.[9] A few days after writing this letter, towards the end of April 1942, he was rounded up, deported and gassed at Bełżec.[10] Another escaped inmate from Chelmno, Mordechaï Podchlebnik, managed to survive the war, and in 1961 gave testimony at the Eichmann trial in Jerusalem.[11][12]
