^ In his testimony, according to Polish historian Aleksander Lasik, "Höss neither protected anyone nor evaded his own responsibility. His stance came as a surprise to many, especially those who viewed him as a bloodthirsty beast. Instead, he viewed his crimes in terms of the technical obstacles and challenges with which he had to cope. Höss stated that he led the killings in Auschwitz on express orders of Reichsführer Himmler."[264]

It has been argued that blitzkrieg was not new; the Germans did not invent something called blitzkrieg in the 1920s and 1930s.[109][151] Rather the German concept of wars of movement and concentrated force were seen in wars of Prussia and the German wars of unification. The first European general to introduce rapid movement, concentrated power and integrated military effort was Swedish King Gustavus Adolphus during the Thirty Years' War. The appearance of the aircraft and tank in the First World War, called an RMA, offered the German military a chance to get back to the traditional war of movement as practised by Moltke the Elder. The so-called "blitzkrieg campaigns" of 1939 – circa 1942, were well within that operational context.[109]
From the first escape on 6 July 1940 of Tadeusz Wiejowski,[215] at least 802 prisoners (757 men and 45 women) tried to escape from the camp, according to Polish historian Henryk Świebocki. He writes that most escapes were attempted from work sites outside the camp.[216][f] Of these, 144 were successful and the fate of 331 is unknown.[217] Four Polish prisoners—Eugeniusz Bendera (a car mechanic at the camp), Kazimierz Piechowski, Stanisław Gustaw Jaster, and a priest, Józef Lempart—escaped successfully on 20 June 1942.[218] After breaking into a warehouse, the four dressed as members of the SS-Totenkopfverbände (the SS units responsible for concentration camps), armed themselves, and stole an SS staff car, which they drove unchallenged through the main gate, greeting several officers with "Heil Hitler!" as they drove past.[219] On 21 July 1944, Polish inmate Jerzy Bielecki dressed in an SS uniform and, using a faked pass, managed to cross the camp's gate with his Jewish girlfriend, Cyla Cybulska (known as Cyla Stawiska), pretending that she was wanted for questioning. Both survived the war. For having saved her, Bielecki was recognized by Yad Vashem as Righteous Among the Nations.[220]
In most ghettos, Nazis ordered the Jews to establish a Judenrat (Jewish council) to administer Nazi demands and to regulate the internal life of the ghetto. The Nazis routinely ordered deportations from the ghettos. In some of the large ghettos, 1,000 people per day were sent by rail to concentration and extermination camps. To get them to cooperate, the Nazis told the Jews they were being transported elsewhere for labor.
Norman Stone detects early Blitzkrieg operations in offensives by the French generals Charles Mangin and Marie-Eugène Debeney in 1918.[e] However, French doctrine in the interwar years became defence-oriented. Colonel Charles de Gaulle advocated concentration of armour and aeroplanes. His opinions appeared in his book Vers l'Armée de Métier (Towards the Professional Army, 1933). Like von Seeckt, de Gaulle concluded that France could no longer maintain the huge armies of conscripts and reservists which had fought World War I, and he sought to use tanks, mechanised forces and aircraft to allow a smaller number of highly-trained soldiers to have greater impact in battle. His views little endeared him to the French high command, but are claimed by some[who?] to have influenced Heinz Guderian.[47]
From 1942 onwards, the camp became the site of one of the greatest mass murders in the history of humanity, committed against the European Jews as part of Hitler's plan for the complete destruction of that people (the Final Solution). An estimated 1.1 million people were killed or died at Auschwitz-Birkenau, the vast majority of whom were Jewish men, women and children deported from their homes all over occupied Europe. They were transported to Auschwitz-Birkenau in overcrowded cattle wagons, and upon arrival sent immediately to their deaths in the Birkenau gas chambers. Their bodies were afterwards cremated in industrial furnaces in the crematoria.
Before the Nazis began their mass slaughter of Jews, they created a number of laws that separated Jews from society. Especially potent was the law that forced all Jews to wear a yellow star upon their clothing. The Nazis also made laws that made it illegal for Jews to sit or eat in certain places and placed a boycott on Jewish-owned stores. Learn more about the persecution of Jews before the death camps.
As was the case in other camps, the primary form of voluntary music-making in Birkenau was singing.  Due to its size and international composition, there were inmates from all over Europe whose voices survivors remembered.  Prisoners sang to comfort one another, to build solidarity and to express resistance.  The former inmate Kitty Hart remembered that
However, Schindler's financial woes continued, and he went bankrupt in 1958. He left his wife Emilie in Argentina to find fortune back in Germany, but despite his efforts, his various businesses repeatedly failed. Again, he had to depend on the charity of the Schindler Jews, many of whom he was still in contact with, to support his well being. In 1963, the same year he declared bankruptcy, he was honored by the State of Israel as Righteous Among the Nations, an award for non Jews who helped save Jews during the Holocaust. A year later, he had a heart attack and spent time recuperating in a hospital.
The first “bunker,” with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra “capacity” was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the “bunkers” were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open.
Ghettos were intended to be temporary until the Jews were deported to other locations, which never happened. Instead, the inhabitants were sent to extermination camps. The ghettos were, in effect, immensely crowded prisons serving as instruments of "slow, passive murder."[216] Though the Warsaw Ghetto contained 30% of Warsaw's population, it occupied only 2.5% of the city's area, averaging over 9 people per room.[217] Between 1940 and 1942, starvation and disease, especially typhoid, killed many in the ghettos.[218] Over 43,000 Warsaw ghetto residents, or one in ten of the total population, died in 1941;[219] in Theresienstadt, more than half the residents died in 1942.[216]
While there were only 23 main camps between 1933 to 1945, the Nazi regime established some 20,000 other camps used for forced labor, transit or temporary internment. During the Holocaust it is estimated that 6 million Jews were slaughtered along with, 3 million Soviet prisoners of war, 3 million Polish Catholics, 700,000 Serbians, 250,000 Gypsies, Sinti, and Lalleri, 80,000 Germans (for political reasons), 70,000 German handicapped, 12,000 homosexuals, and 2,500 Jehovah’s Witnesses.
At the end of the war, in an effort to remove the traces of the crimes they had committed, the SS began dismantling and razing the gas chambers, crematoria, and other buildings, as well as burning documents. Prisoners capable of marching were evacuated into the depths of the German Reich, and thousands of marchers died of hunger, exhaustion and exposure. Those who remained behind in the camp and survived long enough were liberated by Red Army soldiers on 27 January 1945.
In 1914, German strategic thinking derived from the writings of Carl von Clausewitz (June 1, 1780 – November 16, 1831), Helmuth von Moltke the Elder (26 October 1800 – 24 April 1891) and Alfred von Schlieffen (28 February 1833 – 4 January 1913), who advocated manoeuvre, mass and envelopment to create the conditions for a decisive battle (Vernichtungsschlacht). During the war, officers such as Willy Rohr developed tactics to restore manoeuvre on the battlefield. Specialist light infantry (Sturmtruppen, "storm troops") were to exploit weak spots to make gaps for larger infantry units to advance with heavier weapons and exploit the success, leaving isolated strong points to troops following up. Infiltration tactics were combined with short hurricane artillery bombardments using massed artillery, devised by Colonel Georg Bruchmüller. Attacks relied on speed and surprise rather than on weight of numbers. These tactics met with great success in Operation Michael, the spring offensive of 1918 and restored temporarily the war of movement, once the Allied trench system had been overrun. The German armies pushed on towards Amiens and then Paris, coming within 120 kilometres (75 mi) before supply deficiencies and Allied reinforcements halted the advance.[27] Historian James Corum criticised the German leadership for failing to understand the technical advances of the First World War, having given tank production the lowest priority and having conducted no studies of the machine gun prior to that war.[28]
“At this point in the war and in his life, I think Oskar Schindler was absolutely determined to do everything he could to save as many Jews as he could regardless of the cost, either personal or financial,” writes Crowe. “During the last two years of the war, he had undergone a dramatic moral transformation, and, in many ways, he came more and more to associate himself with his Jews than with other Germans.”
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]

In November, attacks erupted against Jewish businesses. At least 91 Jews died and 267 synagogues were destroyed in a centrally coordinated plot passed off as spontaneous violence across Germany. Thousands of Jews were sent to concentration camps and were only released if they agreed to leave the Nazi territory. Many Jews decided to flee, though options were limited. Britain agreed to house Jewish children, eventually taking in 10,000 minors, but refused to change its policy for Jewish adults.

Anti-Semitism in Europe did not begin with Adolf Hitler. Though use of the term itself dates only to the 1870s, there is evidence of hostility toward Jews long before the Holocaust–even as far back as the ancient world, when Roman authorities destroyed the Jewish temple in Jerusalem and forced Jews to leave Palestine. The Enlightenment, during the 17th and 18th centuries, emphasized religious toleration, and in the 19th century Napoleon and other European rulers enacted legislation that ended long-standing restrictions on Jews. Anti-Semitic feeling endured, however, in many cases taking on a racial character rather than a religious one.
^ Many of the German participants of Operation Citadel made no mention of blitzkrieg in their characterisation of the operation. Several German officers and commanders involved in the operation wrote their account of the battle after the war, and some of these postwar accounts were collected by the US Army. Some of these officers are: Theodor Busse (Newton 2002, pp. 3–27), Erhard Raus (Newton 2002, pp. 29–64), Friedrich Fangohr (Newton 2002, pp. 65–96), Peter von der Groeben (Newton 2002, pp. 97–144), Friedrich Wilhelm von Mellenthin (Mellenthin 1956, pp. 212–234), Erich von Manstein (Manstein 1983, pp. 443–449), and others.
Conventional wisdom traces blitzkrieg, “lightning war,” to the development in Germany between 1918 and 1939 of a body of doctrine using mobility to prevent repetition of the attritional deadlock of World War I. Soldiers such as Hans von Seeckt and Heinz Guderian allegedly perceived more clearly than their counterparts elsewhere in Europe the military potential of the internal-combustion engine combined with modern communications technology. Large formations moving on tracks and wheels, directed by radios, could rupture an enemy’s front and so disorganize its rear that countermeasures would be paralyzed. First tested in Poland, the concept reached perihelion in France and the Low Countries in 1940, when in less than six weeks the German army crushed the combined forces of four nations. Applied a year later against the Soviet Union, blitzkrieg purportedly brought the Wehrmacht to the gates of Moscow in six months. Some accounts insist that only Adolf Hitler’s incompetent interference tipped the war’s balance so far against Germany that even blitzkrieg’s most sophisticated refinements could do no more than stave off the Reich’s collapse.

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]
The prisoners' days began at 4:30 am for the men (an hour later in winter), and earlier for the women, when the block supervisor sounded a gong and started beating inmates with sticks to encourage them to wash and use the latrines quickly.[106] Sanitary arrangements were atrocious, with few latrines and a lack of clean water. Each washhouse had to service thousands of prisoners. In sectors BIa and BIb in Auschwitz II-Birkenau, two buildings containing latrines and washrooms were installed in 1943. These contained troughs for washing and 90 faucets; the toilet facilities were "sewage channels" covered by concrete with 58 holes for seating. There were three barracks with washing facilities or toilets to serve 16 residential barracks in BIIa, and six washrooms/latrines for 32 barracks in BIIb, BIIc, BIId, and BIIe.[107] Primo Levi described a 1944 Auschwitz III washroom:
As in the concentration camps, those prisoners selected for work faced appalling conditions and severe treatment. After being woken at dawn, they would have to stand in line for the roll call and endure many hours of hard labour. At the end of the working day, exhausted, they returned to the camp, when they would once again have to stand in line for evening roll call.
During the war, the Condor Legion undertook the bombing of Guernica which had a tremendous psychological effect on the populations of Europe. The results were exaggerated, and the Western Allies concluded that the "city-busting" techniques were now a part of the German way in war. The targets of the German aircraft were actually the rail lines and bridges. But lacking the ability to hit them with accuracy (only three or four Ju 87s saw action in Spain), a method of carpet bombing was chosen resulting in heavy civilian casualties.[80]
The victories of Operation Barbarossa in the summer and fall of 1941 against Hitler's new enemy, the Soviet Union, led to dramatic changes in Nazi anti-Jewish ideology and the profile of prisoners brought to Auschwitz.[37] Construction on Auschwitz II-Birkenau began in October 1941 to ease congestion at the main camp. Reichsführer-SS Heinrich Himmler, head of the Schutzstaffel (SS), intended the camp to house 50,000 prisoners of war, who would be interned as forced laborers. Plans called for the expansion of the camp first to house 150,000 and eventually as many as 200,000 inmates.[38] An initial contingent of 10,000 Soviet prisoners of war arrived at Auschwitz I in October 1941, but by March 1942 only 945 were still alive, and these were transferred to Birkenau, where most of them died from disease or starvation by May.[39] By this time the Nazis had decided to annihilate the Jewish people,[40] so Birkenau became a labor and extermination camp.[39][41]
As the Red Army drew nearer in July 1944, the SS began closing down the easternmost concentration camps and evacuating the remaining prisoners westward to Auschwitz and Gross-Rosen concentration camp. Göth's personal secretary, Mietek Pemper, alerted Schindler to the Nazis' plans to close all factories not directly involved in the war effort, including Schindler's enamelware facility. Pemper suggested to Schindler that production should be switched from cookware to anti-tank grenades in an effort to save the lives of the Jewish workers. Using bribery and his powers of persuasion, Schindler convinced Göth and the officials in Berlin to allow him to move his factory and his workers to Brünnlitz (Czech: Brněnec), in the Sudetenland, thus sparing them from certain death in the gas chambers. Using names provided by Jewish Ghetto Police officer Marcel Goldberg, Pemper compiled and typed the list of 1,200 Jews—1,000 of Schindler's workers and 200 inmates from Julius Madritsch's textiles factory—who were sent to Brünnlitz in October 1944.[62][63][64][65]
