The story of Dutch boxer Leen Sanders who was spared to entertain the Nazi guards and helped others survive Auschwitz.'He had the dream again last night... He taps the gloves of his unbeaten Polish opponent. There are rumours that the loser will be sent to the gas chamber.' In 1943 Leen Sanders, Dutch champion boxer, was sent to Auschwitz. His wife and children were put to death while he was sent 'to the left' with the others fit enough for labor. 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 Sanders 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.A story of astonishing resilience and compassion, The Fighter of Auschwitz is a testament to the endurance of humanity in the face of extraordinary evil.
