Birkenau (Auschwitz II) was established in October 1941, three kilometers from Auschwitz. Exterminations in Birkenau began in March 1942. There were four gas chambers in the camp that used Zyklon B gas. Until November 1944 the camp functioned as a factory for mass murder, receiving transports from all over Europe. Most of those brought to the camp were Jews and nearly all were immediately sent to the gas chambers. Only a small percentage was selected for labor in the camp itself, labor in munitions plants at satellite camps, or the “medical” experiments of Dr. Josef Mengele and his staff. In the spring and summer of 1944, the rate of extermination was increased as the Jews of Hungary and the Lodz ghetto were brought to the camp.
Płaszów concentration camp opened in March 1943 on the former site of two Jewish cemeteries on Jerozilimska Street, about 2.5 kilometres (1.6 mi) from the DEF factory.[49] In charge of the camp was SS-Hauptsturmführer Amon Göth, a sadist who would shoot inmates of the camp at random.[48] Inmates at Płaszów lived in constant fear for their lives.[50] Emilie Schindler called Göth "the most despicable man I have ever met."[51]
Most academic historians regard the notion of blitzkrieg as military doctrine to be a myth. Shimon Naveh wrote "The striking feature of the blitzkrieg concept is the complete absence of a coherent theory which should have served as the general cognitive basis for the actual conduct of operations". Naveh described it as an "ad hoc solution" to operational dangers, thrown together at the last moment.[112] Overy disagreed with the idea that Hitler and the Nazi regime ever intended a blitzkrieg war, because the once popular belief that the Nazi state organised their economy to carry out its grand strategy in short campaigns was false. Hitler had intended for a rapid unlimited war to occur much later than 1939, but the Third Reich's aggressive foreign policy forced the Nazi state into war before it was ready. Hitler and the Wehrmacht's planning in the 1930s did not reflect a blitzkrieg method but the opposite.[113] John Harris wrote that the Wehrmacht never used the word, and it did not appear in German army or air force field manuals; the word was coined in September 1939, by a Times newspaper reporter. Harris also found no evidence that German military thinking developed a blitzkrieg mentality.[114] Karl-Heinz Frieser and Adam Tooze reached similar conclusions to Overy and Naveh, that the notions of blitzkrieg-economy and strategy were myths.[115][116] Frieser wrote that surviving German economists and General Staff officers denied that Germany went to war with a blitzkrieg strategy.[117] Robert M. Citino argues:
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. A few Jews escaped from Birkenau, and there were recorded assaults on Nazi guards even at the entrance to the gas chambers. The 'Sonderkommando' revolt in October 1944 was the extraordinary example of physical resistance.
From 1942, members of the Bureau of Information and Propaganda of the Warsaw-area Home Army published reports based on the accounts of escapees. The first was a fictional memoir, "Oświęcim. Pamiętnik więźnia" ("Auschwitz: Diary of a prisoner") by Halina Krahelska, published in April 1942 in Warsaw.[205] Also published in 1942 was the pamphlet Obóz śmierci (Camp of Death) by Natalia Zarembina,[206] and W piekle (In Hell) by Zofia Kossak-Szczucka, founder of Żegota.[207] In March 1944, the Polish Labor Group in New York published a report in English, "Oswiecim, Camp of Death (Underground Report)", with a foreword by Florence Jaffray Harriman, which described the gassing of prisoners from 1942.[208]
A hedonist and gambler by nature, Schindler soon adopted a profligate lifestyle, carousing into the small hours of the night, hobnobbing with high ranking SS-officers, and philandering with beautiful Polish women. Schindler seemed to be no different from other Germans who had come to Poland as part of the occupation administration and their associates. The only thing that set him apart from other war-profiteers, was his humane treatment of his workers, especially the Jews.
By the end of 1934 Hitler was in absolute control of Germany, and his campaign against the Jews in full swing. The Nazis claimed the Jews corrupted pure German culture with their "foreign" and "mongrel" influence. They portrayed the Jews as evil and cowardly, and Germans as hardworking, courageous, and honest. The Jews, the Nazis claimed, who were heavily represented in finance, commerce, the press, literature, theater, and the arts, had weakened Germany's economy and culture. The massive government-supported propaganda machine created a racial anti-Semitism, which was different from the long­standing anti-Semitic tradition of the Christian churches.
Guderian argued that the tank was the decisive weapon of war. "If the tanks succeed, then victory follows", he wrote. In an article addressed to critics of tank warfare, he wrote "until our critics can produce some new and better method of making a successful land attack other than self-massacre, we shall continue to maintain our beliefs that tanks—properly employed, needless to say—are today the best means available for land attack." Addressing the faster rate at which defenders could reinforce an area than attackers could penetrate it during the First World War, Guderian wrote that "since reserve forces will now be motorized, the building up of new defensive fronts is easier than it used to be; the chances of an offensive based on the timetable of artillery and infantry co-operation are, as a result, even slighter today than they were in the last war." He continued, "We believe that by attacking with tanks we can achieve a higher rate of movement than has been hitherto obtainable, and—what is perhaps even more important—that we can keep moving once a breakthrough has been made." Guderian additionally required that tactical radios be widely used to facilitate co-ordination and command.
Prisoners received half a liter of coffee substitute or a herbal "tea" in the morning, but no food.[109] A second gong heralded roll call, when inmates had to line up outside in rows of ten to be counted. No matter how cold the weather, prisoners had to wait for the SS to arrive for the count. How long they stood there depended on the officers' mood, and whether there had been escapes or other events attracting punishment.[110] Guards might force the prisoners to squat for an hour with their hands above their heads, or hand out beatings or detention for infractions such as having a missing button or an improperly cleaned food bowl. The inmates were counted and re-counted.[111]
Information about Auschwitz became available to the Allies as a result of reports by Captain Witold Pilecki of the Polish Home Army (Armia Krajowa), who volunteered to be imprisoned there in 1940. As "Thomasz Serfiński", he allowed himself to be arrested in Warsaw and spent 945 days in the camp, from 22 September 1940[199] until his escape on 27 April 1943. Michael Fleming writes that Pilecki was instructed to sustain morale, organize food, clothing and resistance, prepare to take over the camp if possible, and smuggle information out to the Polish military.[200] Pilecki called his resistance movement Związek Organizacji Wojskowej (ZOW, "Union of Military Organization").[199]
Concentration camps began to incarcerate ‘habitual criminals’ in addition to political prisoners. Goebbels stepped up anti-Semitic propaganda with a traveling exhibition which cast Jews as the enemy. Nearly half a million people attended. Some guessed worse would come. Winston Churchill criticised British relations with Germany, warning of ‘great evils of racial and religious intolerance’, though many colleagues complained of his ‘harping on’ about Jews.
British theorists J.F.C. Fuller and Captain B. H. Liddell Hart have often been associated with blitzkrieg's development, though this is a matter of controversy. The British War Office did permit an Experimental Mechanised Force, formed on 1 May 1927, that was wholly motorized including self propelled artillery and motorised engineers. It is argued that Guderian, a critical figure in blitzkrieg's conception, drew some of his inspiration from Liddell Hart. This was based on a paragraph in the English edition of Guderian's autobiography in which he credits Liddell Hart. In opposition, it is argued that Liddell Hart, as editor of the autobiography's English edition, wrote that paragraph himself or, more broadly, that his influence on Guderian was not as significant as held. Fuller's influence is less clear. During the war, he developed plans for massive, independent tank operations and was subsequently studied by the German leadership. It is variously argued that Fuller's wartime plans and post-war writings were an inspiration, or that his readership was low and German experiences during the war received more attention.
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.
Reality is at once more limited and more complex. On one level, mobile warfare was a faute de mieux improvisation that arose from the restrictions on conventional forces stipulated by the Treaty of Versailles. The German high command in the 1920s and 1930s also sought inspiration for the future in its own past–specifically in the ideas of Helmuth Karl von Moltke and Alfred von Schlieffen. Tanks, aircraft, and motor trucks were regarded as force multipliers facilitating traditional operational approaches. The aim of German military planners in both the Weimar Republic and the Third Reich was to achieve victory by enveloping enemy armies, threatening their lines of supply and communications, and forcing them to fight in an unexpected direction. The anticipated result would be quick, decisive victories for a state that since the days of Frederick the Great had been convinced of its inability to win a drawn-out war of attrition.

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]
At the three Reinhard camps the victims were killed by the exhaust fumes of stationary diesel engines.[279] Gold fillings were pulled from the corpses before burial, but the women's hair was cut before death. At Treblinka, to calm the victims, the arrival platform was made to look like a train station, complete with fake clock.[300] Majdanek used Zyklon-B gas in its gas chambers.[301] In contrast to Auschwitz, the three Reinhard camps were quite small.[302] Most of the victims at these camps were buried in pits at first. Sobibór and Bełżec began exhuming and burning bodies in late 1942, to hide the evidence, as did Treblinka in March 1943. The bodies were burned in open fireplaces and the remaining bones crushed into powder.[303]
Hitler quickly moved to cement his power by suspending many civil liberties and allowing imprisonment without trial. By March, the first Nazi concentration camp was established at Dachau, not to imprison Jews but to hold political dissidents. Further laws targeted Jews, restricting the jobs they could hold and revoking their German citizenship. Anti-Semitic sentiment increased as the Jewish population was blamed for many of Germany's recent and historical problems.
During the war, Emilie joined Oskar in Krakow, and by the war’s end, the couple was penniless, having used his fortune to bribe authorities and save his workers. The day after the war ended, Schindler and his wife fled to Argentina with the help of the Schindlerjuden to avoid prosecution for his previous spying activities. For more than a decade, Schindler tried farming, only to declare bankruptcy in 1957. He left his wife and traveled to West Germany, where he made an unsuccessful attempt in the cement business. Schindler spent the rest of his life supported by donations from the Schindlerjuden. He was named a Righteous Gentile by Yad Vashem in 1962, and after his death in 1974, at age 66, Oskar Schindler was interred in the Catholic cemetery on Mount Zion in Jerusalem. In 1993, Steven Spielberg brought the story of Oskar Schindler to the big screen with his film, Schindler's List.
Those deemed fit enough for slave labor were then immediately registered, tattooed with a serial number, 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 will set you free”). Of approximately 2.5 million people who were deported to Auschwitz, 405,000 were given prisoner status and serial numbers. Of these, approximately 50% were Jews and 50% were Poles and other nationalities.
Initially, Schindler was mostly interested in the money-making potential of the business and hired Jews because they were cheaper than Poles—the wages were set by the occupying Nazi regime.[38] Later he began shielding his workers without regard for cost.[39] The status of his factory as a business essential to the war effort became a decisive factor enabling him to help his Jewish workers. Whenever Schindlerjuden (Schindler Jews) were threatened with deportation, he claimed exemptions for them. He claimed wives, children, and even people with disabilities were necessary mechanics and metalworkers.[39] On one occasion, the Gestapo came to Schindler demanding that he hand over a family that possessed forged identity papers. "Three hours after they walked in," Schindler said, "two drunk Gestapo men reeled out of my office without their prisoners and without the incriminating documents they had demanded."[40]
