Blitzkrieg, (German: “lightning war”) military tactic calculated to create psychological shock and resultant disorganization in enemy forces through the employment of surprise, speed, and superiority in matériel or firepower. Blitzkrieg is most commonly associated with Nazi Germany during World War II even though numerous combatants used its techniques in that war. Its origins, however, can be traced to the 19th century, and elements of blitzkrieg have been used in present-day conflicts.
By August 1944 there were 105,168 prisoners in Auschwitz whilst another 50,000 Jewish prisoners lived in Auschwitz’s satellite camps. The camp’s population grew constantly, despite the high mortality rate caused by exterminations, starvation, hard labor, and contagious diseases. Upon arrival at the platform in Birkenau, Jews were thrown out of their train cars without their belongings and forced to form two lines, men and women separately.
Although effective in quick campaigns against Poland and France, mobile operations could not be sustained by Germany in later years. Strategies based on manoeuvre have the inherent danger of the attacking force overextending its supply lines, and can be defeated by a determined foe who is willing and able to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front (as opposed to, for example, the Dutch who had no territory to sacrifice). Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks. As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing and blockade. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.
Although not ordered to take part, psychiatrists and many psychiatric institutions were involved in the planning and carrying out of Aktion T4 at every stage. After protests from the German Catholic and Protestant churches, Hitler ordered the cancellation of the T4 program in August 1941, although the disabled and mentally ill continued to be killed until the end of the war. The medical community regularly received bodies and body parts for research. Eberhard Karl University received 1,077 bodies from executions between 1933 and 1945. The neuroscientist Julius Hallervorden received 697 brains from one hospital between 1940 and 1944: "I accepted these brains of course. Where they came from and how they came to me was really none of my business."
To concentrate and monitor the Jewish population as well as to facilitate later deportation of the Jews, the Germans and their collaborators created ghettos, transit camps, and forced-labor camps for Jews during the war years. The German authorities also established numerous forced-labor camps, both in the so-called Greater German Reich and in German-occupied territory, for non-Jews whose labor the Germans sought to exploit.
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. 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. Schindler applied for membership in the Nazi Party on 1 November and was accepted the following year.
