How were people gassed in the holocaust?

Answer 1

About 3.5 million were gassed.

There were a few methods of gassing the Jews. One was the gas vans, which was when the Jews were forced into hermetically sealed vans, and then exhaust gas from the engine was led into the chamber. The Jews were thus suffocated. Then came the gassing at the camps which was one of the most effective killing methods was by forcing Jews into gas chambers, where they were gassed to death using Zyklon B (and to a much lesser degree exhaust fumes). The victims were forced into the gas chamber, the door was closed and either exhaust fumes-gas was fed into the room, or or Zyklon B crystals were dropped in. In the extermination camps at Belzec, Sobibor and Treblinka exhaust fumes were used, while Zyklon B was used in Majdanek and Auschwitz-Birkenau.

Answer 2

Large numbers were gassed only at the extermination camps, which were all located in Poland. They were:

1. Treblinka
2. Auschwitz-Birkenau
3. Majdanek
4. Chelmno
5. Belzec
6. Sobibor

Note that Chelmno used gassing vans and did not have fixed gas chambers.

Some camps, such as Stutthof, had small gas chambers for killing prisoners who had become unfit for work.

Answer 3

they were put into gas chambers, and the gas killed them
