The chief of construction of Auschwitz II-Birkenau was Karl Bischoff, a competent and dynamic bureaucrat who, in spite of the ongoing war, carried out the construction deemed necessary. The Birkenau camp, the four crematoria, a new reception building, and hundreds of other buildings were planned and constructed.[42] Bischoff's plans, based on an initial budget of RM 8.9 million, called for each barracks to hold 550 prisoners. He later changed this to 744 per barracks, which meant the camp could hold 125,000, rather than 97,000.[43] The SS designed the barracks not so much to house people as to destroy them.[42] There were 174 barracks, each measuring 116 by 36 ft, divided into 62 bays of 43 sq. ft. The bays were divided into "roosts", initially for three inmates and later for four. With personal space of 11 sq. ft to sleep and place whatever belongings they had, inmates were deprived, Robert-Jan van Pelt wrote, "of the minimum space needed to exist".[44]
Companies operate in a very similar fashion to military units when it comes to org structures. The army has specialized divisions. Businesses have departments. But instead of focusing on infantry, air or supplies, companies focus on engineering, product, marketing and so on. And the core thing that an executive needs to learn from the application of Blitzkrieg is that all departments need to be synchronized in order for the maneuver to succeed. It may sound obvious considering most executives are familiar with agile methodologies, and more than 70% of companies consider themselves nimble in their approach. Often, however, the actions taken by these same companies contradict how they perceive themselves.
Despite the term blitzkrieg being coined during the Invasion of Poland of 1939, historians generally hold that German operations during it were more consistent with more traditional methods. The Wehrmacht's strategy was more inline with Vernichtungsgedanken, or a focus on envelopment to create pockets in broad-front annihilation. Panzer forces were deployed among the three German concentrations without strong emphasis on independent use, being used to create or destroy close pockets of Polish forces and seize operational-depth terrain in support of the largely un-motorized infantry which followed. The Luftwaffe gained air superiority by a combination of superior technology and numbers. Common claims that the Polish Air Force was destroyed early in the campaign while it was on the ground are not true. Polish aircraft were moved to hidden airstrips approximately 48 hours before the outbreak of the hostilities.
Oskar Schindler renamed the factory Deutsche Emaillewaren-Fabrik (German Enamelware Factory) and started production with a small staff. Possessing a certain panache for business and engaging in influence peddling, Schindler secured numerous German army contracts for kitchenware. He soon met Itzhak Stern, a Jewish accountant, who connected Schindler with Krakow’s Jewish community to staff the factory.
In June 1945 the Soviet authorities took over Auschwitz I and converted it into a POW camp for German prisoners. The hospital had to move beyond the camp perimeter into former administrative buildings, where it functioned until October 1945.[253] Many of the barracks at Birkenau were taken apart by civilians, who used the materials to rebuild their own homes, which had been levelled out in the construction of Auschwitz II. The poorest residents sifted the crematoria ashes in search of nuggets from melted gold, before warning shots were fired.[254] The POW camp for German prisoners of war was used until 1947 by the Soviet NKVD (People's Commissariat for Internal Affairs).[255] The NKVD and its Polish counterpart, the MBP, used the Auschwitz Neu-Dachs sub-camp at Jaworzno to the north of Oświęcim as a concentration camp from 1945 to 1956.[256] The Soviets dismantled and exported the IG Farben factories to the USSR.[257] Meanwhile, Soviet and Polish investigators worked to document the war crimes of the SS.[258] After the site became a museum in 1947, exhumation work lasted for more than a decade.[184]

Those who arrived in Birkenau were driven out of the cattle wagons and put in rows … to this the band played, made up of the best musicians among the prisoners; they played, depending on the origins of the transport, Polish, Czech, or Hungarian folk music.  The band played, the SS pummelled, and you had no time to reflect … some were forced into the camp, the others into the crematoria.
Sometimes the mere presence of German troops in the vicinity was sufficient to spur a massacre. One example is what happened in the Polish village of Jedwabne, where neighbours murdered their Jewish neighbours. For years the massacre was blamed on the Germans, though many Poles likely knew that the local population had turned against its own Jews. In the Baltics, where the Germans were greeted as liberators by some segments of the population, the lure of political independence and the desire to erase any collaboration with the previous Soviet occupiers led nationalist bands to murder local Jews.
In 1942, fifteen Nazi leaders met at a conference in Wannsee, Germany to discuss the “Jewish Question”. Their job was to decide the most efficient way to exterminate the Jews. They decided that Jews would be sent to extermination camps where they would be sent to showers. But instead of water coming out of the faucet, they faced their death when poisonous Zyklon-B gas leaked through the showerheads to suffocate them. This decision at the conference is called the “Final Solution.”
After the war, Albert Speer claimed that the German economy achieved greater armaments output, not because of diversions of capacity from civilian to military industry but through streamlining of the economy. Richard Overy pointed out some 23 percent of German output was military by 1939. Between 1937 and 1939, 70 percent of investment capital went into the rubber, synthetic fuel, aircraft and shipbuilding industries. Hermann Göring had consistently stated that the task of the Four Year Plan was to rearm Germany for total war. Hitler's correspondence with his economists also reveals that his intent was to wage war in 1943–1945, when the resources of central Europe had been absorbed into the Third Reich.[132]
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.[103] After protests from the German Catholic and Protestant churches, Hitler ordered the cancellation of the T4 program in August 1941,[104] although the disabled and mentally ill continued to be killed until the end of the war.[102] 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."[105]
Blitzkrieg's unique and completely flexible campaign structure puts you in control of deciding how your forces will fare in each of the major engagements that comprise three central Campaigns. Hardcore vets have the option of engaging the enemy immediately in a desperate struggle for battlefield dominance, or more cautious players can choose from pre-defined or unlimited randomly generated side missions as they gain experience, promotions and weapons upgrades as well as wear down the enemy before the central conflict.

The impact of the Holocaust varied from region to region and from year to year in the 21 countries that were directly affected. Nowhere was the Holocaust more intense and sudden than in Hungary. What took place over several years in Germany occurred over 16 weeks in Hungary. Entering the war as a German ally, Hungary had persecuted its Jews but not permitted the deportation of Hungarian citizens. In 1941 foreign Jewish refugees were deported from Hungary and were shot by Germans in Kam’yanets-Podilskyy, Ukraine. After Germany invaded Hungary on March 19, 1944, the situation changed dramatically. By mid-April the Nazis had confined Jews to ghettos. On May 15, deportations began, and over the next 55 days the Nazis deported more than 437,000 Jews from Hungary to Auschwitz on 147 trains.
He went on to say that the use of tanks "left much to be desired...Fear of enemy action against the flanks of the advance, fear which was to prove so disastrous to German prospects in the west in 1940 and in the Soviet Union in 1941, was present from the beginning of the war." John Ellis further asserted that "...there is considerable justice in Matthew Cooper's assertion that the panzer divisions were not given the kind of strategic mission that was to characterize authentic armored blitzkrieg, and were almost always closely subordinated to the various mass infantry armies."
On January 20, 1942, several top officials of the German government met to officially coordinate the military and civilian administrative branches of the Nazi system to organize a system of mass murder of the Jews. This meeting, called the Wannsee Conference, "marked the beinning of the full-scale, comprehensive extermination operation [of the Jews] and laid the foundations for its organization, which started immediately after the conference ended" (Yahil, The Holocaust, p. 318).
The concentration and death-camp complex at Auschwitz-Birkenau was the largest killing center in the entire Nazi universe; the very heart of their system. Of the many sub-camps affiliated with Auschwitz, Birkenau, or Auschwitz II, was by far the largest. The main camp, Auschwitz I was on the outskirts of the Polish city Oswiecim. Birkenau was in a suiburb named Zasole.

Schindler was the eldest of two children born to a farm machinery manufacturer and his wife. Svitavy, where the family lived, was located in the Sudetenland, and, though the region passed from the Austrian Empire to Czechoslovakia in 1918, the Schindlers were ethnically German. After leaving school in 1924, Schindler sold farm equipment for his father, during which time he met his future wife, Emilie, whom he married in 1928. He took a variety of odd jobs, including running a driving school, before enlisting for a stint in the Czechoslovak army. Schindler then briefly lived in Berlin before returning to Czechoslovakia to start a poultry farm, which he soon abandoned. A self-professed sybarite, he spent much of his time drinking and philandering.

The understanding of operations in Poland has shifted considerably since the Second World War. Many early postwar histories incorrectly attribute German victory to "enormous development in military technique which occurred between 1918 and 1940", incorrectly citing that "Germany, who translated (British inter-war) theories into action...called the result Blitzkrieg." More recent histories identify German operations in Poland as relatively cautious and traditional. Matthew Cooper wrote that

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]
