History of Europe

When did the Nazi stop using gas chambers?

The Nazis stopped using gas chambers for mass killings in November 1944. The last major use of gas chambers occurred at the Auschwitz-Birkenau concentration camp, where approximately 437,000 Hungarian Jews were gassed to death between May and November 1944. The Nazis dismantled the gas chambers and crematoria at Auschwitz-Birkenau in order to conceal evidence of their crimes as the Soviet Red Army approached.
