Many people ask, "Why didn't the Jews fight back?" Well, they did. With limited weapons and at a severe disadvantage, they found creative ways to subvert the Nazi system. They worked with partisans in the forests, fought to the last man in the Warsaw Ghetto, revolted at the Sobibor death camp, and blew up gas chambers at Auschwitz. Learn more about the resistance, both by Jews and non-Jews, to the Nazis.
Ellis, as well as Zaloga in his study of the Polish Campaign in 1939, points to the effective use of other arms such as artillery and aerial firepower as equally important to the success of German (and later, Allied) operations. Panzer operations in Russia failed to provide decisive results; Leningrad never fell despite an entire Panzer Group being assigned to take it, nor did Moscow. In 1942 panzer formations overstretched at Stalingrad and in the Caucasus, and what successes did take place - such as Manstein at Kharkov or Krivoi Rog - were of local significance only.
The government defined a Jewish person as someone with three or four Jewish grandparents, not someone who had religious convictions. This meant that people who had never practiced, or hadn’t practiced Judaism in many years, or even converted to Christianity were subjected to persecution. Although anti-semitism was pervasive in 1930s Germany, these restrictions frequently extended to any person the Nazis considered to be “non-Aryan”.
In a blitzkrieg, tanks and troop-transport vehicles were concentrated, and massive attacks by dive bombers were conducted on enemy front-line positions. When these forces had broken through, they continued deep into enemy territory, encircling and cutting off the enemy. The techniques were first developed by the German army late in World War I in an effort to overcome static trench warfare, but the Germans lacked the mobility to succeed. Between the wars, armored tactics were further developed by Basil Liddell Hart and J. F. C. Fuller in Britain, Charles de Gaulle in France, and Heinz Guderian in Germany. Made chief of German mobile troops in 1938, Guderian led the drive across France in 1940.
By January 1945 Soviet troops were advancing towards Auschwitz. In desperation to withdraw, the Nazis sent most of the 58,000 remaining prisoners on a death march to Germany, and most prisoners were killed en route. When the Soviet army liberated Auschwitz on January 27, soldiers found only 7,650 barely living prisoners throughout the entire camp complex. In all, approximately one million Jews had been murdered there.

The political situation in Germany and elsewhere in Europe after World War I (1914–1918) contributed to the rise of virulent antisemitism. Many Germans did not accept that their country had been defeated, which gave birth to the stab-in-the-back myth. This insinuated that it was disloyal politicians, chiefly Jews and communists, who had orchestrated Germany's surrender. Inflaming the anti-Jewish sentiment was the apparent over-representation of Jews in the leadership of communist revolutionary governments in Europe, such as Ernst Toller, head of a short-lived revolutionary government in Bavaria. This perception contributed to the canard of Jewish Bolshevism.[65]

SS officers, including the infamous Dr. Josef Mengele, would conduct selections among these lines, sending most victims to one side and thus condemning them to death in the gas chambers. A minority was sent to the other side, destined for forced labor. Those who were sent to their deaths were killed that same day and their corpses were burnt in the crematoria. Those not sent to the gas chambers were taken to “quarantine,” where their hair was shaved, striped prison uniforms distributed, and registration took place. Prisoners’ individual registration numbers were tattooed onto their left arm.
His tasks for the Abwehr included collecting information on railways, military installations, and troop movements, as well as recruiting other spies within Czechoslovakia, in advance of a planned invasion of the country by Nazi Germany.[9] He was arrested by the Czech government for espionage on 18 July 1938 and immediately imprisoned, but was released as a political prisoner under the terms of the Munich Agreement, the instrument under which the Czech Sudetenland was annexed into Germany on 1 October.[10][11] Schindler applied for membership in the Nazi Party on 1 November and was accepted the following year.[12]
