Recognising that battlefield conditions changed rapidly and that orders often became overtaken by events, the German army encouraged its commanders to make decisions without waiting for orders from above, thus allowing them to take advantage of fleeting opportunities as they arose. Above all else, this doctrine created aggressive and flexible leaders.
Meanwhile, beginning in the fall of 1939, Nazi officials selected around 70,000 Germans institutionalized for mental illness or disabilities to be gassed to death in the so-called Euthanasia Program. After prominent German religious leaders protested, Hitler put an end to the program in August 1941, though killings of the disabled continued in secrecy, and by 1945 some 275,000 people deemed handicapped from all over Europe had been killed. In hindsight, it seems clear that the Euthanasia Program functioned as a pilot for the Holocaust.
Known as block 13 until 1941, block 11 of Auschwitz I was the prison within the prison, where violators of the numerous rules were punished. To extract information from them, guards would hold inmates' heads held against the stove, burning their faces and eyes. Some prisoners were made to spend the nights in standing cells. Measuring 1.5 m2 (16 sq ft), the cells held four men who could do nothing but stand, and who were forced the following day to work as usual.[136] In other cells, inmates were subjected to hanging with their hands behind their backs, thus dislocating their shoulder joints. In the basement were the "dark cells", which had only a 5 x 5 cm opening and a solid door. Prisoners placed in these cells gradually suffocated as they ran out of oxygen; sometimes the SS lit a candle in the cell to use up the oxygen more quickly.[137]
By Guderian's account he single-handedly created the German tactical and operational methodology. Between 1922 and 1928 Guderian wrote a number of articles concerning military movement. As the ideas of making use of the combustible engine in a protected encasement to bring mobility back to warfare developed in the German army, Guderian was a leading proponent of the formations that would be used for this purpose. He was later asked to write an explanatory book, which was titled Achtung Panzer! (1937). In it he explained the theories of the tank men and defended them.
David M. Crowe’s book Oskar Schindler: The Untold Account of His Life, Wartime Activities and the True Story Behind The List should be considered a classic in investigative and historical research. Based on interviews with dozens of Holocaust survivors saved by Oskar Schindler and with access to documents unavailable to Schindler’s List author Thomas Keneally, Crowe sheds light on one of the most dramatic and important stories to come out of World War II.
The Auschwitz I main camp was a place of extermination, effected mainly by depriving people of elementary living conditions. It was also a centre for immediate extermination. Here were located the offices of the camp’s administration, the local garrison commander and the commandant of Auschwitz I, the seat of the central offices of the political department, and the prisoner labour department. Here too were the main supply stores, workshops and Schutzstaffel (SS) companies. Work in these administrative and economic units and companies was the main form of forced labour for the inmates in this camp.

Thus although the Nazi 'Final Solution' was one genocide among many, it had features that made it stand out from all the rest as well. Unlike all the others it was bounded neither by space nor by time. It was launched not against a local or regional obstacle, but at a world-enemy seen as operating on a global scale. It was bound to an even larger plan of racial reordering and reconstruction involving further genocidal killing on an almost unimaginable scale, aimed, however, at clearing the way in a particular region – Eastern Europe – for a further struggle against the Jews and those the Nazis regarded as their puppets. It was set in motion by ideologues who saw world history in racial terms. It was, in part, carried out by industrial methods. These things all make it unique.
Later manifestations of blitzkrieg tactics were the combined air and ground attacks by Israeli forces on Syria and Egypt during the Six-Day War (June 1967) and the Israeli counterattacks and final counteroffensive of the Yom Kippur War (October 1973). The “left hook” flanking maneuver executed by U.S. Gen. Norman Schwarzkopf during the Persian Gulf War also utilized elements of blitzkrieg tactics, with a combined arms offensive that destroyed the Iraqi army in Kuwait in a period of just three days.
Those deported to Auschwitz arrived at the nearby train station and were marched or trucked to the main camp where they were registered, tattooed, undressed, deloused, had their body hair shaven off, showered while their clothes were disinfected with Zyklon-B gas, and entered the camp under the infamous gateway inscribed 'Arbeit Macht Frei' ("Labor make you free")
With the deportations from Hungary, the role of Auschwitz-Birkenau in the German plan to murder the Jews of Europe achieved its highest effectiveness. Between late April and early July 1944, approximately 440,000 Jews were deported from Hungary. Of the nearly 426,000 Hungarian Jews deported to Auschwitz, approximately 320,000 of them were sent directly to the gas chambers in Auschwitz-Birkenau. They deployed approximately 110,000 at forced labor in the Auschwitz camp complex. The SS authorities transferred many of these Hungarian Jewish forced laborers within weeks of their arrival in Auschwitz to other concentration camps in Germany and Austria.
In 1980, Australian author Thomas Keneally by chance visited Pfefferberg's luggage store in Beverly Hills while en route home from a film festival in Europe. Pfefferberg took the opportunity to tell Keneally the story of Oskar Schindler. He gave him copies of some materials he had on file, and Keneally soon decided to make a fictionalised treatment of the story. After extensive research and interviews with surviving Schindlerjuden, his 1982 historical novel Schindler's Ark (published in the United States as Schindler's List) was the result.[94]
The Blitzkrieg was fundamentally about moving away from the tried and tested methods of modern warfare and creating a new, more effective doctrine. To that end, Hitler had given his full backing to Guderian. Ironically, he had got his idea for Blitzkrieg from two officers – one from France and one from Britain and he had copied and broadened what they had put on paper. In Britain and France, however, the cavalry regiments ruled supreme and they were adamant that the tanks would not get any influence in their armies. The High Commands of both countries were dominated by the old traditional cavalry regiments and their political pull was great. These were the type of officers despised by Hitler and he took to his Panzer officer, Guderian, over the old officers that were in the German Army (the Wehrmacht). 

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]
