Quick Summary

Treblinka II was a Nazi extermination camp in occupied Poland, established in July 1942 as part of Operation Reinhard. Its primary purpose was the mass murder of Jews as part of the Holocaust.12

Upon arrival by train, victims were separated, stripped, and led to buildings where they were gassed with carbon monoxide from diesel engines. Those unable to walk were killed in a ditch. Treblinka II was second only to Auschwitz in the number of Jews killed, with an estimated 750,000 to 900,000 deaths. The camp was closed in October 1943.12
