~ In early 1940, the use of hydrogen cyanide produced by Zyklon B was tested on 250 Roma children from Brno at the Buchenwald concentration camp.
~On September 3, 1941, 600 Soviet POWs were gassed with Zyklon B at Auschwitz camp I; this was the first experiment with the gas at Auschwitz.
~Carbon monoxide was also used in large purpose-built gas chambers.
~Some stationary gas chambers could kill 2,500 people at once.
~Rudolf Hoess, Commandant of the Auschwitz concentration camp, attested to the use of gas chambers in the Holocaust.
~The gas chambers were dismantled or destroyed when Soviet troops got close, except at Dachau, Sachsenhausen, and Majdanek.
~The gas chamber at Auschwitz I was reconstructed after the war as a memorial, but without a door in its doorway and without the wall that originally separated the gas chamber from a washroom. The door that had been added when the gas chamber was converted into an air raid shelter was left intact.
Note: They were neacked entering the chambers !!!!! (they were foolled thing they was getting a bath / shower)
