Some Jews pretended that they weren't Jewish. No one had proof that you were Jewish. Other Jews jumped over the immense wire fence, which is very dangerous. There is some people that survived the Holocaust that are still alive today, and they say that some of them jumped over the fence. Once you jumped over the fence, soldiers would start shooting at you. But if you were lucky, then you wouldnt get hurt. The Holocaust was horrible, the Jews in the Concentration Camps, and more. I dont know what Hitler did and why, but it was HORRIBLE!
