German volunteers first used armor in live field conditions during the Spanish Civil War of 1936. Armor commitments consisted of Panzer Battalion 88, a force built around three companies of PzKpfw I tanks that functioned as a training cadre for Nationalists. The Luftwaffe deployed squadrons of fighters, dive-bombers, and transports as the Condor Legion. Guderian called the tank deployment "on too small a scale to allow accurate assessments to be made." The true test of his "armored idea" would have to wait for the Second World War. However, the German Air Force also provided volunteers to Spain to test both tactics and aircraft in combat, including the first combat use of the Stuka.
The gate house was built in 1943, long after the Birkenau camp was first opened. The first inmates, who were Soviet Prisoners of War, arrived at Birkenau on October 7, 1941. At first, the gate shown in the photo above was for trucks and pedestrians. Railroad tracks were not laid through the gate until the Spring of 1944, just before transports of Hungarian Jews began to arrive. According to the Auschwitz Museum, 434,351 of these Hungarian Jews were not registered at Birkenau; instead, they were gassed immediately upon arrival. At the height of the deportation of the Hungarian Jews, during a 10 week period, up to 12,000 Jews were gassed and burned each day.

On 7 November 1938, Herschel Grynszpan, a Polish Jew, shot the German diplomat Ernst vom Rath in the German Embassy in Paris, in retaliation for the expulsion of his parents and siblings from Germany.[118][k] When vom Rath died on 9 November, the government used his death as a pretext to instigate a pogrom against the Jews throughout the Third Reich. The government claimed it was spontaneous, but in fact it had been ordered and planned by Hitler and Goebbels, although with no clear goals, according to David Cesarani; the result, he writes, was "murder, rape, looting, destruction of property, and terror on an unprecedented scale".[120][121]

Several SS personnel oversaw the killings at each gas chamber, while the bulk of the work was done by the mostly Jewish prisoners known as Sonderkommandos (special squads).[91][92] Hungarian doctor Miklós Nyiszli reported that the Sonderkommando numbered around 860 prisoners when the Hungarian Jews were being killed in May–July 1944.[93] Their responsibilities included removing goods and corpses from the incoming trains, guiding victims to the dressing rooms and gas chambers, and working in the "Canada" barracks, where the victims' possessions were stored.[94] Housed separately from other prisoners, in somewhat better conditions, their quality of life was further improved by access to the goods taken from murdered prisoners, which they were sometimes able to steal and trade on Auschwitz's black market.[95] Many Sonderkommandos committed suicide in response to the horrors of their work; others were generally shot by the SS in a matter of weeks. New Sonderkommando units were formed from incoming transports. Almost none of the 2,000 prisoners placed in these units survived to the camp's liberation.[96]

In October 1944, the 'Sonderkommando' crew crematoria IV revolted and destroyed the crematories. In November Himmler ordered gassings to stop, and a 'cleanup' operation was inaugurated to conceal traces of the mass murder. In January 1945, the Germans evacuated 58,000 prisoners who could walk. They left behind in the main camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long.
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
On January 20, 1942, Reinhard Heydrich convened the Wannsee Conference at a lakeside villa in Berlin to organize the “final solution to the Jewish question.” Around the table were 15 men representing government agencies necessary to implement so bold and sweeping a policy. The language of the meeting was clear, but the meeting notes were circumspect:
On November 9-10, 1938, the attacks on the Jews became violent. Hershel Grynszpan, a 17-year-old Jewish boy distraught at the deportation of his family, shot Ernst vom Rath, the third secretary in the German Embassy in Paris, who died on November 9. Nazi hooligans used this assassination as the pretext for instigating a night of destruction that is now known as Kristallnacht (the night of broken glass). They looted and destroyed Jewish homes and businesses and burned synagogues. Many Jews were beaten and killed; 30,000 Jews were arrested and sent to concentration camps.

In 1988, West Germany allocated another $125 million for reparations. Companies such as BMW, Deutsche Bank, Ford, Opel, Siemens, and Volkswagen faced lawsuits for their use of forced labor during the war.[463] In response, Germany set up the "Remembrance, Responsibility and Future" Foundation in 2000, which paid €4.45 billion to former slave laborers (up to €7,670 each).[465] In 2013, Germany agreed to provide €772 million to fund nursing care, social services, and medication for 56,000 Holocaust survivors around the world.[466] The French state-owned railway company, the SNCF, agreed in 2014 to pay $60 million to Jewish-American survivors, around $100,000 each, for its role in the transport of 76,000 Jews from France to extermination camps between 1942 and 1944.[467]

Military trucks loaded with bread arrived on 28 January, and volunteers began to offer first aid and improvised assistance the following week.[249] The liberation of the camp received little Western press attention at the time. Laurence Rees attributes this to three factors: the previous discovery of similar crimes at the Majdanek concentration camp, competing news from the Allied summit at Yalta, and the Soviet Union's Marxist presentation of the camp "as the ultimate capitalist factory where the workers were dispensible", combined with its interest in minimizing attention to Jewish suffering.[252]
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 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.

As you walk about the camp it is not difficult to picture the squalor and anguish that victims had to endure. The living accommodation tended to be built like makeshift barns. There were no foundations, and little defense against the elements. Unsurprisingly, inmates were plagued by ill-health - the bitterness of the Polish winter must have been unbearable.

At the outbreak of war, the German army had no radically new theory of war. The operational thinking of the German army had not changed significantly since the First World War or since the late 19th century. J. P. Harris and Robert M. Citino point out that the Germans had always had a marked preference for short, decisive campaigns – but were unable to achieve short-order victories in First World War conditions. The transformation from the stalemate of the First World War into tremendous initial operational and strategic success in the Second, was partly the employment of a relatively small number of mechanised divisions, most importantly the Panzer divisions, and the support of an exceptionally powerful air force.[152]
The number of Afro-Germans in Germany when the Nazis came to power is variously estimated at 5,000–25,000.[454] It is not clear whether these figures included Asians. Although blacks, including prisoners of war, in Germany and German-occupied Europe were subjected to incarceration, sterilization, murder, and other abuse, there was no programme to kill them all as there was for the Jews.[455]

Of the 430,000 sent to the first death camp at Bełżec in Poland, there were only two survivors. 700,000 were killed at Treblinka in just five months. In July, Himmler ordered that all Jews in key areas of Poland, except for those needed for essential labour, were to be killed by the end of the year. Most were. Despite Allied intelligence receiving detailed reports of the mass murders in Europe, the public reaction in Britain was largely a mixture of apathy and disbelief.
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.
