What agent was used to kill people in the gas chambers at Treblinka?
It might have been cyanide, or steam, or diesel engine exhaust, or gasoline engine exhaust, or some delayed-action mystery gas. It depends on the source consulted. Since the camp was dismantled long before the war ended, it is entirely speculation that gas chambers existed at Treblinka at all. The official version of events appears based on the reports of Gerstein and confessions of others who were either stationed at the camp, or survived it as inmates. This version centers around the use of engine exhaust. Diesel engine exhaust is most frequently alleged.
