Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]

In 1995, David Glantz stated that for the first time, blitzkrieg was defeated in summer and the opposing Soviet forces were able to mount a successful counter-offensive.[98] The Battle of Kursk ended with two Soviet counter-offensives and the revival of deep operations.[98] In the summer of 1944, the Red Army destroyed Army Group Centre in Operation Bagration, using combined-arms tactics for armour, infantry and air power in a coordinated strategic assault, known as deep operations, which led to an advance of 600 kilometres (370 mi) in six weeks.[106]

The photo below shows the railroad siding inside the camp, called the ramp, where the Jews exited from the trains and the selection process took place. Those who were fit for work were allowed to live for a few months, until they inevitably died of disease or overwork. The others were sent immediately to one of the four gas chambers at the far end of the camp. The gas chambers in Krema II and Krema III were at the end of the main camp road, which is shown on the left in the photo below. The railroad tracks extend about a mile into the camp, all the way to the gas chambers II and III; some of the Hungarian Jews were immediately gassed without going through a selection process, even though the Nazis were desperately in need of workers for their munitions factories. This photo was taken in the early morning, looking west from the gate house tower.

Guderain recognised the importance of tanks  © This doctrine integrated the operational-level ideas taught by Schlieffen with the tactical concepts developed during World War One. And as military technology, including that of tanks, motor vehicles, aircraft and radios, was developed during the 1920s and 30s, so it was grafted onto this doctrinal framework.
In fall 1941, the Nazis began transporting Jews out of the ghetto. Most of them were sent to the Bełżec extermination camp and killed.[45] On 13 March 1943, the ghetto was liquidated and those still fit for work were sent to the new concentration camp at Płaszów.[46] Several thousand not deemed fit for work were sent to extermination camps and killed. Hundreds more were killed on the streets by the Nazis as they cleared out the ghetto. Schindler, aware of the plans because of his Wehrmacht contacts, had his workers stay at the factory overnight to prevent them coming to harm.[47] Schindler witnessed the liquidation of the ghetto and was appalled. From that point forward, says Schindlerjude Sol Urbach, Schindler "changed his mind about the Nazis. He decided to get out and to save as many Jews as he could."[48]
The Nuremberg trials were a series of military tribunals, held by the Allied forces after World War II in Nuremberg, Germany, to prosecute prominent members of the political, military, and economic leadership of Nazi Germany. The first of these trials was the 1945–1946 trial of the major war criminals before the International Military Tribunal (IMT).[456] This tribunal tried 22 political and military leaders of the Third Reich,[457] except for Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, all of whom had committed suicide several months before.[456]
Another important correction to the historical record: Itzhak Stern, played in the movie by Ben Kingsley, was actually a composite of a number of people, including Mietek Pemper, who played a crucial role in putting Oskar Schindler in the position to save many people. Pemper had the unfortunate task of being forced to work as the assistant to Amon Goth, the sadistic commandant of the Krakow-Płaszow concentration camp. In that position, Pemper passed along valuable information to Oskar. As the German war effort neared collapse, Pemper told Schindler he needed to expand into armaments because only factories deemed vital to the war effort would be viewed worth saving, along with, it was hoped, the workers in those factories.
Pogroms occurred in several countries occupied by, or supportive of, Germany, attacks that were both encouraged by the Germans and carried out without their involvement.[225] Thousands of Jews were killed in January and June 1941 in the Bucharest pogrom and Iaşi pogrom in Romania, a German ally.[226] According to a 2004 report written by Tuvia Friling and others, up to 14,850 Jews died during the Iaşi pogrom.[227] The Romanian military killed up to 25,000 Jews in Odessa, then under Romanian control, between 18 October 1941 and March 1942, assisted by gendarmes and the police.[228] Mihai Antonescu, Romania's deputy prime minister, is reported as saying it was "the most favorable moment in our history" to solve the "Jewish problem".[229] In July 1941 he said it was time for "total ethnic purification, for a revision of national life, and for purging our race of all those elements which are foreign to its soul, which have grown like mistletoes and darken our future".[230]
Schindler joined the separatist Sudeten German Party in 1935.[6] Although he was a citizen of Czechoslovakia, Schindler became a spy for the Abwehr, the military intelligence service of Nazi Germany, in 1936. He was assigned to Abwehrstelle II Commando VIII, based in Breslau.[7] He later told Czech police that he did it because he needed the money; by this time Schindler had a drinking problem and was chronically in debt.[8]
