Several million foreigners in a condition of slavery, overworked, despised, undernourished, badly clothed, and badly cared for, cut off from all contact with their native land. They were not 'typical prisoners', they did not have integrity, on the contrary they were demoralized and depleted....For them escape was difficult and extremely dangerous; besides being demoralized, they had been weakened by hunger and maltreatment; they were and knew they were considered worth less than beasts of burden. Their heads were shaved, their filthy clothes were immediately recognizable, their wooden clogs made a swift and silent step impossible. If they were foreigners, they had neither acquaintances nor viable places of refuge in the surroundings....The particular, but numerically imposing, case of the Jews was the most tragic....In what direction could they flee? To whom could they turn for shelter? They were outside the world, men and women made of air.
