As late as 19 April 1945, prisoners were sent to KZ Dachau; on that date a freight train from Buchenwald with nearly 4,500 was diverted to Nammering. SS troops and police confiscated food and water, which local townspeople tried to give to the prisoners. Nearly three hundred dead bodies were ordered removed from the train and carried to a ravine over 400 metres (.25 mi) away. The 524 prisoners who had been forced to carry the dead to this site were then shot by the guards, and buried along with those who had died on the train. Nearly 800 bodies went into this mass grave.
Between the years 1933 and 1945, more than 3.5 million Germans were imprisoned in such concentration camps or prison for political reasons. Approximately 77,000 Germans were killed for one or another form of resistance by Special Courts, courts-martial, and the civil justice system. Many of these Germans had served in government, the military, or in civil positions, which were considered to enable them to engage in subversion and conspiracy against the Nazis.
As the tide of World War II turned against the Nazis, they began a systematic plan to eliminate or "liquidate" the ghettos they had established, by a combination of mass murder on the spot and transferring the remaining residents to extermination camps. When the Nazis attempted to liquidate the Warsaw Ghetto on April 13, 1943, the remaining Jews fought back in what has become known as the Warsaw Ghetto Uprising. The Jewish resistance fighters held out against the entire Nazi regime for 28 days, longer than many European countries had been able to withstand Nazi conquest.
In September 1939, Germany invaded Poland, starting World War II. Schindler left his wife and traveled to Krakow, hoping to profit from the impending war. Looking for business opportunities, he quickly became involved in the black market. By October, Schindler used his charm and doled out “gifts of gratitude” (contraband goods) to bribe high-ranking German officers. Wanting to expand his business interests, Schindler obtained a former Jewish enamelware factory to produce goods for the German military.
In 1935 the Wehrmacht began to build a large military complex close to the village of Belsen, a part of the town of Bergen, in what was then the Province of Hanover. This became the largest military training area in Germany of the time and was used for armoured vehicle training. The barracks were finished in 1937. The camp has been in continuous operation since then and is today known as Bergen-Hohne Training Area. It is used by the NATO armed forces.
