Auschwitz originally was conceived as a concentration camp, to be used as a detention center for the many Polish citizens arrested after Germany annexed the country in 1939. These detainees included anti-Nazi activists, politicians, resistance members and luminaries from the cultural and scientific communities. Once Hitler’s Final Solution became official Nazi policy, however, Auschwitz was deemed an ideal death camp locale. For one thing, it was situated near the center of all German-occupied countries on the European continent. For another, it was in close proximity to the string of rail lines used to transport detainees to the network of Nazi camps.
Auschwitz became a significant source of slave labor locally and functioned as an international clearing house. Of 2.5 million people who were deported to Auschwitz, 405,000 were given prisoner status and serial numbers. Of these, approximately 50 percent were Jews and 50 percent were Poles and other nationalities. Of those who received numbers, 65,000 survived. It is estimated that about 200,000 people passed through the Auschwitz camps and survived.
The Theresienstadt family camp, which existed between September 1943 and July 1944, served a different purpose. A group of around 5,000 Jews had arrived in Auschwitz in September 1943 from the Theresienstadt ghetto in Czechoslovakia. The families were allowed to stay together, their heads were not shaved, and they could wear their own clothes. Correspondence between Adolf Eichmann's office and the International Red Cross suggests that the Germans set up the camp to cast doubt on reports, in time for a planned Red Cross visit to Auschwitz, that mass murder was taking place in Auschwitz. A second group of 5,000 arrived from Theresienstadt in December 1943. On 7 March 1944, the first group was sent to the gas chamber at crematorium III; before they died, they were asked to send postcards to relatives, postdated to 25 March.[148] This was the largest massacre of Czechoslovak citizens in history. News of the liquidation reached the Czechoslovak government-in-exile, which initiated diplomatic manoeuvers to save the remaining Jews. After the Red Cross visited Theresienstadt in June 1944 and were persuaded by the SS that no deportations were taking place from there, about 3,500 Jews were removed from the family camp to other sections of Auschwitz. The remaining 6,500 were murdered in the gas chambers between 10 and 12 July 1944.[149][150]
By mid-1942, the majority of those being sent by the Nazis to Auschwitz were Jews. Upon arriving at the camp, detainees were examined by Nazi doctors. Those detainees considered unfit for work, including young children, the elderly, pregnant women and the infirm, were immediately ordered to take showers. However, the bathhouses to which they marched were disguised gas chambers. Once inside, the prisoners were exposed to Zyklon-B poison gas. Individuals marked as unfit for work were never officially registered as Auschwitz inmates. For this reason, it is impossible to calculate the number of lives lost in the camp.
^ Jump up to: a b Dan Stone (Histories of the Holocaust, 2010): "Europe's Romany (Gypsy) population was also the victim of genocide under the Nazis. Many other population groups, notably Poles, Ukrainians, and Soviet prisoners of war were killed in huge numbers, and smaller groups such as Jehovah's Witnesses, Black Germans, and homosexuals suffered terribly under Nazi rule. The evidence suggests that the Slav nations of Europe were also destined, had Germany won the war, to become victims of systematic mass murder; and even the terrible brutality of the occupation in eastern Europe, especially in Poland, can be understood as genocidal according to the definition put forward by Raphael Lemkin in his major study, Axis Rule in Occupied Europe (1944), the book that introduced the term 'genocide' to our vocabulary. Part of the reason for today's understanding, though, is a correct assessment of the fact that for the Nazis the Jews were regarded in a kind of 'metaphysical' way; they were not just considered as racially inferior (like Romanies), deviants (like homosexuals) or enemy nationals standing in the way of German colonial expression (like Slavs). ... [T]he Jews were to some extent outside of the racial scheme as defined by racial philosophers and anthropologists. They were not mere Untermenschen (sub-humans) ... but were regarded as a Gegenrasse: "a 'counter-race', that is to say, not really human at all. ... 'Holocaust', then, refers to the genocide of the Jews, which by no means excludes an understanding that other groups—notably Romanies and Slavs—were victims of genocide. Indeed ... the murder of the Jews, although a project in its own right, cannot be properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans."[32]
When the Nazi’s rose to power they built facilities to hold and, eventually kill, their enemies. When the first concentration camps were built in 1933, this primarily meant political dissidents and opponents of the Nazi government, such as German Communists, Socialists, Social Democrats but would grow to include asocial groups – Gypsies, Jehovah’s Witnesses, the homeless, the mentally ill and homosexuals.  It was not until Kristallnacht that the prisoners became primarily Jewish.
Never one to miss a chance to make money, he marched into Poland on the heels of the SS. He dived headfirst into the black-market and the underworld and soon made friends with the local Gestapo bigwigs, softening them up with women, money and illicit booze. His newfound connections helped him acquire a factory which he ran with the cheapest labor around: Jewish.
“I suddenly see Steinlauf, my friend aged almost fifty, with nude chest, scrub his neck and shoulders with little success (he has no soap) [He] sees me and asks me severely why I do not wash. Why should I wash? Would I be better off than I am? Would I please someone more? Would I live a day longer?…. Does Steinlauf not know that after half an hour with the coal sacks every difference between him and me will have disappeared?….

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]
On April 16, 1945 Soviets surrounded Berlin, Germany’s capital. When the Soviets began advancing towards the Reich Chancellery, Hitler committed suicide on April 30, 1945. Then on May 7th, Germany surrendered to the Western Allies in Reims, France and a few days later to the Soviets in Berlin. All told more than 60 million people, or about 3% of the world’s population at the time, were killed during the course of the Second World War.

The prosecution entered indictments against 24 major war criminals[z] and seven organizations—the leadership of the Nazi party, the Reich Cabinet, the Schutzstaffel (SS), Sicherheitsdienst (SD), the Gestapo, the Sturmabteilung (SA) and the "General Staff and High Command". The indictments were for: participation in a common plan or conspiracy for the accomplishment of a crime against peace; planning, initiating and waging wars of aggression and other crimes against peace; war crimes; and crimes against humanity. The tribunal passed judgements ranging from acquittal to death by hanging.[458] Eleven defendants were executed, including Joachim von Ribbentrop, Wilhelm Keitel, Alfred Rosenberg, and Alfred Jodl. Ribbentrop, the judgement declared, "played an important part in Hitler's 'final solution of the Jewish question'".[459]
Blitzkrieg was based on speed, co-ordination and movement; the major science of this approach was the ability to get large mobile forces through weak points in the enemies defences and then cause damage when behind his static lines. With large formations cut off from communication and logistics, pressure could then be put on interior defences. Its aim was to create panic amongst the civilian population. A civil population on the move can be absolute havoc for a defending army trying to get its forces to the war front. With so much focus placed on the frontline, if this could be penetrated then the ensuing doubt, confusion and rumour were sure to paralyse both the government and the defending military.
Other historians wrote that blitzkrieg was an operational doctrine of the German armed forces and a strategic concept on which the leadership of the Third Reich based its strategic and economic planning. Military planners and bureaucrats in the war economy appear rarely, if ever, to have employed the term blitzkrieg in official documents. That the German army had a "blitzkrieg doctrine" was rejected in the late 1970s by Matthew Cooper. The concept of a blitzkrieg Luftwaffe was challenged by Richard Overy in the late 1970s and by Williamson Murray in the mid-1980s. That the Third Reich went to war on the basis of "blitzkrieg economics" was criticised by Richard Overy in the 1980s and George Raudzens described the contradictory senses in which historians have used the word. The notion of a German blitzkrieg concept or doctrine survives in popular history and many historians still support the thesis.[110]
The Allies believed that 'blitzkrieg' was dependent on new technology, such as tanks and dive-bombers  © Shocked by their experience, the Allied military observers who had survived the fall of France attributed their defeat to the completely new form of warfare pioneered by the Wehrmacht - the blitzkrieg. Blitzkrieg seemed to be based around the pervasive use of new technology. After all, during the disastrous campaign in Belgium and France, it had seemed as if German tanks and aircraft were everywhere.
Use of armoured forces was crucial for both sides on the Eastern Front. Operation Barbarossa, the German invasion of the Soviet Union in 1941, involved a number of breakthroughs and encirclements by motorised forces. Its goal according to Führer Directive 21 (18 December 1940) was "to destroy the Russian forces deployed in the West and to prevent their escape into the wide-open spaces of Russia."[90] The Red Army was to be destroyed west of the Dvina and Dnieper rivers, which were about 500 kilometres (310 mi) east of the Soviet border, to be followed by a mopping-up operation. The surprise attack resulted in the near annihilation of the Voyenno-Vozdushnye Sily (VVS, Soviet Air Force) by simultaneous attacks on airfields,[91] allowing the Luftwaffe to achieve total air supremacy over all the battlefields within the first week.[92][93] On the ground, four German panzer groups outflanked and encircled disorganised Red Army units, while the marching infantry completed the encirclements and defeated the trapped forces.[94] In late July, after 2nd Panzer Group (commanded by Guderian) captured the watersheds of the Dvina and Dnieper rivers near Smolensk, the panzers had to defend the encirclement, because the marching infantry divisions were still hundreds of kilometres to the west.[91]
Yugoslavia and Greece were invaded in April 1941 and surrendered before the end of the month. Germany and Italy divided Greece into occupation zones but did not eliminate it as a country. Yugoslavia, home to around 80,000 Jews, was dismembered; regions in the north were annexed by Germany and regions along the coast made part of Italy. The rest of the country was divided into the Independent State of Croatia, nominally an ally of Germany, and Serbia, which was governed by a combination of military and police administrators.[167] According to historian Jeremy Black, Serbia was declared free of Jews in August 1942.[168] Croatia's ruling party, the Ustashe, killed the country's Jews, and killed or expelled Orthodox Christian Serbs and Muslims.[167] Jews and Serbs alike were "hacked to death and burned in barns", according to Black. One difference between the Germans and Croatians was that the Ustashe allowed its Jewish and Serbian victims to convert to Catholicism so they could escape death.[168]
The Germans isolated all the camps and sub-camps from the outside world and surrounded them with barbed wire fencing. All contact with the outside world was forbidden. However, the area administered by the commandant and patrolled by the SS camp garrison went beyond the grounds enclosed by barbed wire. It included an additional area of approximately 40 square kilometers (the so-called “Interessengebiet” - the interest zone), which lay around the Auschwitz I and Auschwitz II-Birkenau camps.
Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]
The Reichswehr and the Red Army began a secret collaboration in the Soviet Union to evade the Treaty of Versailles occupational agent, the Inter-Allied Commission. In 1926, War games and tests were begun at Kazan and Lipetsk. The centres were used to field test aircraft and armoured vehicles up to the battalion level and housed aerial and armoured warfare schools, through which officers were rotated.[50]

After their defeat in 1918, German military intellectuals began reshaping the army. Under the direction of Hans von Seeckt, commanders fashioned the doctrine that the Wehrmacht was to employ in World War Two. Repelled by the waste and indecisiveness of trench warfare, they returned to the ideas of Schlieffen, and in 1921 the army published its new doctrine, Command and Combat with Combined Arms.

I have only ever seen this film once, I only ever want to see this film once and I will only ever need to see this film once. It is etched on my mind. I, like many others, left in silence. I could not imagine inventing a critical analysis of this film, picking small points of detail or of style, or even scoring points off the Director. It stands alone as a monumental piece of cinema, a magnificent accomplishment.
The influence of air forces over forces on the ground changed significantly over the course of the Second World War. Early German successes were conducted when Allied aircraft could not make a significant impact on the battlefield. In May 1940, there was near parity in numbers of aircraft between the Luftwaffe and the Allies, but the Luftwaffe had been developed to support Germany's ground forces, had liaison officers with the mobile formations, and operated a higher number of sorties per aircraft.[71] In addition, German air parity or superiority allowed the unencumbered movement of ground forces, their unhindered assembly into concentrated attack formations, aerial reconnaissance, aerial resupply of fast moving formations and close air support at the point of attack.[citation needed] The Allied air forces had no close air support aircraft, training or doctrine.[71] The Allies flew 434 French and 160 British sorties a day but methods of attacking ground targets had yet to be developed; therefore Allied aircraft caused negligible damage. Against these 600 sorties the Luftwaffe on average flew 1,500 sorties a day.[72] On May 13, Fliegerkorps VIII flew 1,000 sorties in support of the crossing of the Meuse. The following day the Allies made repeated attempts to destroy the German pontoon bridges, but German fighter aircraft, ground fire and Luftwaffe flak batteries with the panzer forces destroyed 56 percent of the attacking Allied aircraft while the bridges remained intact.[73]
Oskar Schindler was born into a German Catholic family on April 28, 1908. After attending trade schools, he worked for his father’s farm machinery company. He worked for German intelligence and later joined the Nazi Party. An opportunist businessman with a taste for the finer things in life, he seemed an unlikely candidate to become a wartime hero. During the war, however, he operated a factory that employed more than 1,000 Polish Jews, saving them from concentration camps and extermination. In 1993 his story was made into the Steven Spielberg feature film Schindler's List.
"The persecution of Jews in occupied Poland meant that we could see horror emerging gradually in many ways. In 1939, they were forced to wear Jewish stars, and people were herded and shut up into ghettos. Then, in the years '41 and '42 there was plenty of public evidence of pure sadism. With people behaving like pigs, I felt the Jews were being destroyed. I had to help them. There was no choice."
Blitzkrieg tactics were used in the successful German invasions of Belgium, the Netherlands, and France in 1940, which saw audacious applications of air power and airborne infantry to overcome fixed fortifications that were believed by the defenders to be impregnable. The Kesselschlacht campaigns on the Eastern Front were staggering in scale, with Kessels that covered vast swathes of territory, enveloping hundreds of thousands of troops. Blitzkrieg tactics were also used by the German commander Erwin Rommel during the desert campaigns in North Africa.

German doctors performed a variety of experiments on prisoners at Auschwitz. SS doctors tested the efficacy of X-rays as a sterilization device by administering large doses to female prisoners. Carl Clauberg injected chemicals into women's uteruses in an effort to glue them shut. Prisoners were infected with spotted fever for vaccination research and exposed to toxic substances to study the effects.[125] In one experiment Bayer, then part of IG Farben, paid RM 150 each for 150 female inmates from Auschwitz (the camp had asked for RM 200 per woman), who were transferred to a Bayer facility to test an anesthetic. A Bayer employee wrote to Rudolf Höss: "The transport of 150 women arrived in good condition. However, we were unable to obtain conclusive results because they died during the experiments. We would kindly request that you send us another group of women to the same number and at the same price." The Bayer research was led at Auschwitz by Helmuth Vetter of Bayer/IG Farben, who was also an Auschwitz physician and SS captain, and by Auschwitz physicians Friedrich Entress and Eduard Wirths.[126]
Germany invaded Norway and Denmark on 9 April 1940, during Operation Weserübung. Denmark was overrun so quickly that there was no time for an organized resistance to form. Consequently, the Danish government stayed in power and the Germans found it easier to work through it. Because of this, few measures were taken against the Danish Jews before 1942.[157] By June 1940 Norway was completely occupied.[158] In late 1940, the country's 1,800 Jews were banned from certain occupations, and in 1941 all Jews had to register their property with the government.[159] On 26 November 1942, 532 Jews were taken by police officers, at four o'clock in the morning, to Oslo harbour, where they boarded a German ship. From Germany they were sent by freight train to Auschwitz. According to Dan Stone, only nine survived the war.[160]

Schindler moved to West Germany after the war, where he was supported by assistance payments from Jewish relief organisations. After receiving a partial reimbursement for his wartime expenses, he moved with his wife, Emilie, to Argentina, where they took up farming. When he went bankrupt in 1958, Schindler left his wife and returned to Germany, where he failed at several business ventures and relied on financial support from Schindlerjuden ("Schindler Jews")—the people whose lives he had saved during the war. He and his wife, Emilie, were named Righteous Among the Nations by the Israeli government in 1993. He died on 9 October 1974 in Hildesheim, Germany, and was buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way.
