Les enceintes, les barbelés, les miradors, les baraquements, les potences, les chambres à gaz et les fours crématoires de l'ancien camp de concentration et d'extermination d'Auschwitz-Birkenau, le plus vaste du IIIe Reich, attestent les conditions dans lesquelles fonctionnait le génocide hitlérien. Selon des recherches historiques, 1,1 à 1,5 million de personnes – dont de très nombreux Juifs – furent systématiquement affamées, torturées et assassinées dans ce camp, symbole de la cruauté de l'homme pour l'homme au XXe siècle.
Tens of thousands of Jews held in the eastern territories were marched towards the heart of Germany so they could not bear witness to the Allies. Aware that the world had been alerted to the horrors of the camps, the Nazis sought to destroy evidence. In June, Soviet forces liberated the first major camp, known as Majdanek, in Lublin, Poland. The Nazis had burned down the crematorium chimney but had failed to destroy the gas chambers and barracks. Only a few hundred inmates were still alive.
Entering conquered Soviet territories alongside the Wehrmacht (the German armed forces) were 3,000 men of the Einsatzgruppen (“Deployment Groups”), special mobile killing units. Their task was to murder Jews, Soviet commissars, and Roma in the areas conquered by the army. Alone or with the help of local police, native anti-Semitic populations, and accompanying Axis troops, the Einsatzgruppen would enter a town, round up their victims, herd them to the outskirts of the town, and shoot them. They killed Jews in family units. Just outside Kiev, Ukraine, in the ravine of Babi Yar, an Einsatzgruppe killed 33,771 Jews on September 28–29, 1941. In the Rumbula Forest outside the ghetto in Riga, Latvia, 25,000–28,000 Jews were shot on November 30 and December 8–9. Beginning in the summer of 1941, Einsatzgruppen murdered more than 70,000 Jews at Ponary, outside Vilna (now Vilnius) in Lithuania. They slaughtered 9,000 Jews, half of them children, at the Ninth Fort, adjacent to Kovno (now Kaunas), Lithuania, on October 28.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
