The crematoria consisted of a dressing room, gas chamber, and furnace room. In crematoria II and III, the dressing room and gas chamber were underground; in IV and V, they were on the ground floor. The dressing room had numbered hooks on the wall to hang clothes. In crematorium II, there was also a dissection room (Sezierraum).[171] SS officers told the victims they were to take a shower and undergo delousing. The victims undressed in the dressing room and walked into the gas chamber, which was disguised as a shower facility; signs in German said "To the baths" and "To disinfection". Some inmates were even given soap and a towel.[172]

According to Polish historian Andrzej Strzelecki, the evacuation of the prisoners by the SS in January 1945 was one of the camp's "most tragic chapters".[234] In mid-1944, about 130,000 prisoners were in Auschwitz when the SS moved around half of them to other concentration camps.[235] In November 1944, with the Soviet Red Army approaching through Poland, Himmler ordered gassing operations to cease. The crematorium IV building was dismantled,[236] and the Sonderkommando was ordered to remove evidence of the killings, including the mass graves.[237] The SS destroyed written records, and in the final week before the camp's liberation, burned or demolished many of its buildings.[238] The plundered goods from the "Canada" barracks at Birkenau, together with building supplies, were transported to the German interior. On 20 January, the overflowing warehouses were set ablaze. Crematoria II and III at Birkenau were blown up on 20 January and crematorium V six days later, just one day ahead of the Soviet attack.[236]
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]
German volunteers first used armour in live field conditions during the Spanish Civil War of 1936. Armour commitment consisted of Panzer Battalion 88, a force built around three companies of Panzer I tanks that functioned as a training cadre for Nationalists. The Luftwaffe deployed squadrons of fighters, dive bombers and transport aircraft as the Condor Legion.[77] Guderian said that the tank deployment was "on too small a scale to allow accurate assessments to be made."[78] The true test of his "armoured idea" would have to wait for the Second World War. However, the Luftwaffe also provided volunteers to Spain to test both tactics and aircraft in combat, including the first combat use of the Stuka.[79]
On May 8, 1945, the war in Europe ended, and the next day Schindler and his wife fled the country with the help of several of the Schindlerjuden, as the Jews he saved came to be known. Schindler was wanted for war crimes in Czechoslovakia due to his earlier espionage activities. In 1949 they settled in Argentina with several of the Jewish families they had saved. Having spent the bulk of his profiteering fortune on bribes, Schindler unsuccessfully attempted to farm. He went bankrupt in 1957 and the next year traveled alone to West Germany, where he made an abortive entry into 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 was interred in the Catholic cemetery on Mount Zion in Jerusalem.
The SS: The SS was a military-style group of Nazis, founded in 1925, who were like Hitler's personal bodyguards. They were in charge of overseeing the killing of people in the camps. Part of the SS called the Einsatzgruppen were put in charge of killing many people, before the extermination camps were opened to carry this out on a much greater scale. The SS also took control of intelligence, security and the police force.
By the end of the war, Schindler had spent his entire fortune on bribes and black market purchases of supplies for his workers.[80] Virtually destitute, he moved briefly to Regensburg and later Munich, but did not prosper in postwar Germany. In fact, he was reduced to receiving assistance from Jewish organisations.[39] In 1948 he presented a claim for reimbursement of his wartime expenses to the American Jewish Joint Distribution Committee, and received $15,000.[81] He estimated his expenditures at over $1,056,000, including the costs of camp construction, bribes, and expenditures for black market goods, including food.[82] Schindler emigrated to Argentina in 1949, where he tried raising chickens and then nutria, a small animal raised for its fur. When the business went bankrupt in 1958, he left his wife and returned to Germany, where he had a series of unsuccessful business ventures, including a cement factory.[83][84] He declared bankruptcy in 1963 and suffered a heart attack the next year, which led to a month-long stay in hospital.[85] Remaining in contact with many of the Jews he had met during the war, including Stern and Pfefferberg, Schindler survived on donations sent by Schindlerjuden from all over the world.[84][86] He died on 9 October 1974 and is buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way.[39][84] For his work during the war, on 8 May 1962, Yad Vashem invited Schindler to a ceremony during which a carob tree planted in his honor on the Avenue of the Righteous.[87] He and his wife, Emilie, were named Righteous Among the Nations, an award bestowed by the State of Israel on non-Jews who took an active role to rescue Jews during the Holocaust, on 24 June 1993.[88] Other awards include the German Order of Merit (1966).[89]

Dynatron was Schindler's elevator drive system launched in 1965. It is based on Schlieren's Monotron drive which was developed in 1958. These drive systems are particularly distinguished by direct stopping, regulated electronically as a function of the distance to the floor level. Dynatron should not be confused with Schindler's Dynator (Ward Leonard) drive, which was introduced in 1945.
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.
The crematoria consisted of a dressing room, gas chamber, and furnace room. In crematoria II and III, the dressing room and gas chamber were underground; in IV and V, they were on the ground floor. The dressing room had numbered hooks on the wall to hang clothes. In crematorium II, there was also a dissection room (Sezierraum).[171] SS officers told the victims they were to take a shower and undergo delousing. The victims undressed in the dressing room and walked into the gas chamber, which was disguised as a shower facility; signs in German said "To the baths" and "To disinfection". Some inmates were even given soap and a towel.[172]
Hitler’s worldview revolved around two concepts: territorial expansion (that is, greater Lebensraum—“living space”—for the German people) and racial supremacy. After World War I the Allies denied Germany colonies in Africa, so Hitler sought to expand German territory and secure food and resources—scarce during World War I—in Europe itself. Hitler viewed the Jews as racial polluters, a cancer on German society in what has been termed by Holocaust survivor and historian Saul Friedländer “redemptive anti-Semitism,” focused on redeeming Germany from its ills and ridding it of a cancer on the body politic. Historian Timothy Snyder characterized the struggle as even more elemental, as “zoological,” and “ecological,” a struggle of the species. Hitler opposed Jews for the values they brought into the world. Social justice and compassionate assistance to the weak stood in the way of what he perceived as the natural order, in which the powerful exercise unrestrained power. In Hitler’s view, such restraint on the exercise of power would inevitably lead to the weakening, even the defeat, of the master race.
In 1939, shortly after the war began, the Germans initiated the T4 Program—framed euphemistically as a “euthanasia” program—for the murder of intellectually or physically disabled and emotionally disturbed Germans who by their very existence violated the Nazi ideal of Aryan supremacy. They were termed “life unworthy of life.” An economic justification was also employed as these Germans were considered “useless eaters.” The Nazis pioneered the use of gas chambers and mass crematoria under this program. The murder of the disabled was the training ground for key personnel who were to later staff the death camps of Aktion Reinhard. The German public protested these murders. The Roman Catholic bishop of Münster, Clemens August, Graf von Galen, preached against them, and the T4 program was formally halted. Nonetheless, the murder and sterilization of these German “Aryans” continued secretly throughout the war.
In general, subcamps that produced or processed agricultural goods were administratively subordinate to Auschwitz-Birkenau. Subcamps whose prisoners were deployed at industrial and armaments production or in extractive industries (e.g., coal mining, quarry work) were administratively subordinate to Auschwitz-Monowitz. This division of administrative responsibility was formalized after November 1943.
Moreover, one of the key successes of the Blitzkrieg was its use of FM radios – these enabled the forces that had broken through the lines to inform support units as to their progress and relay information on what was behind enemy lines. This superior intelligence was a crucial tool at the German’s disposal and allowed them to perform far more organised assaults on the enemy. The communication technology promoted quick, decentralised decision-making that was key to this speed focused approach.
Ellis, as well as Zaloga in his study of the Polish Campaign in 1939, points to the effective use of other arms such as artillery and aerial firepower as equally important to the success of German (and later, Allied) operations. Panzer operations in Russia failed to provide decisive results; Leningrad never fell despite an entire Panzer Group being assigned to take it, nor did Moscow. In 1942 panzer formations overstretched at Stalingrad and in the Caucasus, and what successes did take place - such as Manstein at Kharkov or Krivoi Rog - were of local significance only.
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]
In the Lviv pogroms in occupied Poland in July 1941, some 6,000 Polish Jews were murdered in the streets, on top of 3,000 arrests and mass shootings by Einsatzgruppe C.[231][m] During the Jedwabne pogrom, on 10 July 1941, a group of 40 Polish men killed several hundred Jews; around 300 were burned alive in a barn. The attack is thought to have been organized by the German Security Police (Sicherheitsdienst).[233] A long debate about who was responsible for the Jedwabne murders was triggered in 2001 by the publication of Jan T. Gross's book Neighbors: The Destruction of the Jewish Community in Jedwabne, Poland.[234] The response to the book was described as "the most prolonged and far-reaching of any discussion of the Jewish issue in Poland since the Second World War".[235]
Between 1942 and 1944, the SS authorities at Auschwitz established 44 subcamps. Some of them were established within the officially designated “development” zone, including Budy, Rajsko, Tschechowitz, Harmense, and Babitz. Others, such as Blechhammer, Gleiwitz, Althammer, Fürstengrube, Laurahuette, and Eintrachthuette were located in Upper Silesia north and west of the Vistula River. Some subcamps, such as Freudenthal and Bruenn (Brno), were located in Moravia.
In his 1983 book, Popular Opinion and Political Dissent in the Third Reich, Ian Kershaw examined the Alltagsgeschichte (history of everyday life) in Bavaria during the Nazi period. The most common viewpoint of Bavarians was indifference towards what was happening to the Jews, he wrote. Most Bavarians were vaguely aware of the genocide, but they were vastly more concerned about the war.[472] Kershaw argued that "the road to Auschwitz was built by hate, but paved with indifference".[473] His assessment faced criticism from historians Otto Dov Kulka and Michael Kater. Kater maintained that Kershaw had downplayed the extent of popular antisemitism. Although most of the "spontaneous" antisemitic actions of Nazi Germany had been staged, Kater argued that these had involved substantial numbers of Germans, and therefore it was wrong to view the extreme antisemitism of the Nazis as coming solely from above.[474] Kulka argued that "passive complicity" would be a better term than "indifference".[475] Focusing on the views of Germans opposed to the Nazi regime, the German historian Christof Dipper, in his essay "Der Deutsche Widerstand und die Juden" (1983), argued that the majority of the anti-Nazi national-conservatives were antisemitic. No one in the German resistance supported the Holocaust, but Dipper wrote that the national conservatives did not intend to restore civil rights to the Jews after the planned overthrow of Hitler.[474]
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.
Overy wrote that blitzkrieg as a "coherent military and economic concept has proven a difficult strategy to defend in light of the evidence".[127] Milward's theory was contrary to Hitler's and German planners' intentions. The Germans, aware of the errors of the First World War, rejected the concept of organising its economy to fight only a short war. Therefore, focus was given to the development of armament in depth for a long war, instead of armament in breadth for a short war. Hitler claimed that relying on surprise alone was "criminal" and that "we have to prepare for a long war along with surprise attack". During the winter of 1939–40, Hitler demobilised many troops from the army to return as skilled workers to factories because the war would be decided by production, not a quick "Panzer operation".[128]
Although she struggled with resentment towards her late husband for his womanizing and marital neglect, Emilie still had profound love for Schindler. Revealing her internal dialogue when she visited his tomb almost 40 years after his passing, she had said to him: "At last we meet again . . .I have received no answer, my dear, I do not know why you abandoned me . . . But what not even your death or my old age can change is that we are still married, this is how we are before God. I have forgiven you everything, everything. . ."
In March 1951, the government of Israel requested $1.5 billion from the Federal Republic of Germany to finance the rehabilitation of 500,000 Jewish survivors, arguing that Germany had stolen $6 billion from the European Jews. Israelis were divided about the idea of taking money from Germany. The Conference on Jewish Material Claims Against Germany (known as the Claims Conference) was opened in New York, and after negotiations, the claim was reduced to $845 million.[463][464]
Birkenau was the largest of the more than 40 camps and sub-camps that made up the Auschwitz complex. During its three years of operation, it had a range of functions. When construction began in October 1941, it was supposed to be a camp for 125 thousand prisoners of war. It opened as a branch of Auschwitz in March 1942, and served at the same time as a center for the extermination of the Jews. In its final phase, from 1944, it also became a place where prisoners were concentrated before being transferred to labor in German industry in the depths of the Third Reich.
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]
