Oskar Schindler, (born April 28, 1908, Svitavy [Zwittau], Moravia, Austria-Hungary [now in the Czech Republic]—died October 9, 1974, Hildesheim, West Germany), German industrialist who, aided by his wife and staff, sheltered approximately 1,100 Jews from the Nazis by employing them in his factories, which supplied the German army during World War II.

Half of the German divisions available in 1940 were combat ready but less well-equipped than the British and French or the Imperial German Army of 1914. In the spring of 1940, the German army was semi-modern, in which a small number of well-equipped and "elite" divisions were offset by many second and third rate divisions".[135] In 2003, John Mosier wrote that while the French soldiers in 1940 were better trained than German soldiers, as were the Americans later and that the German army was the least mechanised of the major armies, its leadership cadres were larger and better and that the high standard of leadership was the main reason for the successes of the German army in World War II, as it had been in World War I.[136]
Overnight on November 9-10, 1938, the Nazis incited a pogrom against Jews in Austria and Germany called Kristallnacht (Night of Broken Glass, or literally translated from German, "Crystal Night"). This included the pillaging and burning of synagogues, the breaking of windows of Jewish-owned businesses and the looting of those stores. In the morning, broken glass littered the ground. Many Jews were physically attacked or harassed, and approximately 30,000 were arrested and sent to concentration camps.
The twin pairs of gas chambers were numbered II and III, and IV and V. The first opened on March 31, 1943, the last on April 4, 1943. The total area of the gas chambers was 2,255 square meters; the capacity of these crematoria was 4,420 people. Those selected to die were undressed in the undressing room and then pushed into the gas chambers. It took about 20 minutes for all the people to death. In II and III, the killings took place in underground rooms, and the corpses were carried to the five ovens by an electrically operated lift. Before cremation gold teeth and any other valuables, such as rings, were removed from the corpses. In IV and V the gas chambers and ovens were on the same level, but the ovens were so poorly built and the usage was so great that they repeatedly malfunctioned and had to be abandoned. The corpses were finally burned outside, in the open, as in 1943. Jewish sonderkommandos worked the crematoria under SS supervision.
The invasion of France consisted of two phases, Operation Yellow (Fall Gelb) and Operation Red. Yellow opened with a feint conducted against the Netherlands and Belgium by two armoured corps and paratroopers. Three days later, the main effort of Panzer Group von Kleist attacked through the Ardennes and achieved a breakthrough with air support. The group raced to the coast of the English Channel, dislodging the British Expeditionary Force, Belgian Army, and some divisions of the French Army. The motorized units initially advanced far beyond the following divisions. When the German motorized forces were met with a counterattack at the Battle of Arras (1940), British tanks with heavy armour (Matilda I & IIs) created a brief panic in the German High Command. The motorized forces were halted outside the port city of Dunkirk which was being used to evacuate the Allied forces. Hermann Göring had promised his Luftwaffe would complete the job but aerial operations did not prevent the evacuation of the majority of Allied troops (which the British named Operation Dynamo); some 330,000 French and British. Operation Red then began with XV Panzer Corps attacking towards Brest and XIV Panzer Corps attacking south, east of Paris, towards Lyon, and XIX Panzer Corps completing the encirclement of the Maginot Line. The defending forces were hard pressed to organize any sort of counter-attack. The French forces were continually ordered to form new lines along rivers, often arriving to find the German forces had already passed them.
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.[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]
