In 1943, the Dutch champion boxer, Leen Sanders, was sent to Auschwitz. His wife and children were put to death while he was sent 'to the left' with the others who were fit enough for labour. Recognised by an SS officer, he was earmarked for a 'privileged' post in the kitchens in exchange for weekly boxing matches for the entertainment of the Nazi guards. From there, he enacted his resistance to their limitless cruelty. With great risk and danger to his own life, Leen stole, concealed and smuggled food and clothing from SS nursing units for years to alleviate the unbearable suffering of the prisoners in need. He also regularly supplied extra food to the Dutch women in Dr Mengele's experiment, Block 10. To his fellow Jews in the camp, he acted as a rescuer, leader and role model, defending them even on their bitter death march to Dachau towards the end of the war.
