Sobibor extermination camp
The camp closed after a prisoner revolt, which took place on 14 October 1943. The plan for the revolt had two phases. In the first phase, teams of prisoners were to discreetly assassinate each of the SS officers who ran the camp. In the second phase, all 600 prisoners would assemble for evening roll call and would walk to freedom out the front gate. However, the plan was disrupted after only 11 of the SS officers had been killed. The prisoners had to escape by climbing over barbed wire fences and running through a field of landmines while the SS tried to shoot them with machine guns. About 300 prisoners made it out of the camp. Of these, 58 are known to have survived the war.
