How Hitler hide the death camps?
many Jews believed they were only being deported and that death camps were simply refugee camps until new home was found. They also did not believe the rumours aout the camps as they were a big economic force in Gemany, especially with the war. Hitler disguised the camps as factories (often rubber factories) saying the Jews were forced labourers (also explains the smell). Allies only heard rumours and could not really retaliate anyway. They could not go by sea, or risk the swarms of U-boats. They could not bomb the camps or risk more death. Land was only option and they were doing that anyway.
