After the Polen-campaign in 1939 the Germany began the systematic extention of the jews. In the beginning the jews where killed by massexetjusions and borrowd in mass. When the world war II began, the Germans built many concentrations camps in Poland. And there they sent the jews, and all the others who they ment not should live, like homophiles and the handicapped. The strong people did work, but those who was not so strong was directly sent in to the gas chamber.
Those gas chamber could hall 2000 peoples, and the gas came out of false showers. The jews was told to get a shower, so they all took of their clothes and went in. It almost took 5 to 30 minuts before they died because the Germans didn`t care to find the right dose with gas. When everybody was dead, they cut the hair, and they took out the teeth and the organ to the people who was dead. The organs was used to research. And the germans gave the clothes to the other prisoners.
