The German invasion of France, with subsidiary attacks on Belgium and the Netherlands, consisted of two phases, Operation Yellow (Fall Gelb) and Operation Red (Fall Rot). Yellow opened with a feint conducted against the Netherlands and Belgium by two armoured corps and paratroopers. Most of the German armoured forces were placed in Panzer Group von Kleist, which attacked through the Ardennes, a lightly defended sector that the French planned to reinforce if need be, before the Germans could bring up heavy and siege artillery.[h] There was no time for such a reinforcement to be sent, for the Germans did not wait for siege artillery but reached the Meuse and achieved a breakthrough at the Battle of Sedan in three days.
A symbol of innocence in the movie, the little girl in the red coat who appears during the liquidation of the ghetto in the movie was based on a real person. In the film, the little girl is played by actress Oliwia Dabrowska, who—at the age of three—promised Spielberg that she would not watch the film until she was 18 years old. She allegedly watched the movie when she was 11, breaking her promise, and spent years rejecting the experience. Later, she told the Daily Mail, “I realized I had been part of something I could be proud of. Spielberg was right: I had to grow up to watch the film.”
There was initially little to distinguish Schindler from the other businessmen who cooperated with the Nazis, until the liquidation of the Kraków ghetto threatened the workers he relied on. As the war dragged on and Schindler began to build personal relationships with his workers, he underwent a personal transformation. Over time, Schindler became less concerned with making a profit; soon he was spending enormous sums of money to keep his workers safe.
After examining several sites for a new plant to manufacture Buna-N, a type of synthetic rubber essential to the war effort, the German chemical cartel IG Farben chose a site near the towns of Dwory and Monowice (Monowitz in German), about 7 kilometres (4.3 mi) east of Auschwitz I. Tax exemptions were available to corporations prepared to develop industries in the frontier regions under the Eastern Fiscal Assistance Law, passed in December 1940. The site had good railway connections and access to raw materials. In February 1941, Himmler ordered that the Jewish population of Oświęcim be expelled to make way for skilled laborers; that all Poles able to work remain in the town and work on building the factory; and that Auschwitz prisoners be used in the construction work.
During this period, all the war's major combatants developed mechanized force theories. Theories of the Western Allies differed substantially from the Reichswehr's. British, French, and American doctrines broadly favored a more set-piece battle, less combined arms focus, and less focus on concentration. Early Reichswehr periodicals contained many translated works, though they were often not adopted. Technical advances in foreign countries were, however, observed and used in-part by the Weapons Office. Foreign doctrines are widely considered to have had little serious influence.
The mass killings of Jews in the occupied Soviet territories were assigned to four SS formations called Einsatzgruppen ("task groups"), which were under Heydrich's overall command. Similar formations had been used to a limited extent in Poland in 1939, but the ones operating in the Soviet territories were much larger. The Einsatzgruppen's commanders were ordinary citizens: the great majority were professionals and most were intellectuals. By the winter of 1941–1942, the four Einsatzgruppen and their helpers had killed almost 500,000 people. The largest massacre of Jews by the mobile killing squads in the Soviet Union was at a ravine called Babi Yar outside Kiev, where 33,771 Jews were killed in a single operation on 29–30 September 1941.[n] A mixture of SS and Security Police, assisted by Ukrainian police, carried out the killings. Although they did not actively participate in the killings, men of the German 6th Army helped round up the Jews of Kiev and transport them to be shot. By the end of the war, around two million are thought to have been victims of the Einsatzgruppen and their helpers in the local population and the German Army. Of those, about 1.3 million were Jews and up to a quarter of a million Roma.
After attending primary and secondary school, Schindler enrolled in a technical school, from which he was expelled in 1924 for forging his report card. He later graduated, but did not take the Abitur exams that would have enabled him to go to college or university. Instead, he took courses in Brno in several trades, including chauffeuring and machinery, and worked for his father for three years. A fan of motorcycles since his youth, Schindler bought a 250-cc Moto Guzzi racing motorcycle and competed recreationally in mountain races for the next few years.
