Allied air superiority became a significant hindrance to German operations during the later years of the war. Early German successes enjoyed air superiority with unencumbered movement of ground forces, close air support, and aerial reconnaissance. However, the Western Allies' air-to-ground aircraft were so greatly feared out of proportion to their actual tactical success, that following the lead up to Operation Overlord German vehicle crews showed reluctance to move en masse during daylight. Indeed, the final German blitzkrieg operation in the west, Operation Wacht am Rhein, was planned to take place during poor weather which grounded Allied aircraft. Under these conditions, it was difficult for German commanders to employ the "armoured idea" to its envisioned potential.
Those prisoners capable, began forcibly marching at the moment when Soviet soldiers were liberating Cracow, some 60 kilometers from the camp. In marching columns escorted by heavily armed SS guards, these 58,000 men and women prisoners were led out of Auschwitz from January 17-21. Many prisoners lost their lives during this tragic evacuation, known as the Death March.

During the era of the Holocaust, German authorities also targeted other groups because of their perceived racial and biological inferiority: Roma (Gypsies), people with disabilities, and some of the Slavic peoples (Poles, Russians, and others). Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals.
Between April and June of 1940, Germany invaded Norway, Denmark, the Netherlands, Belgium, and Luxembourg consolidating power across neutral Western Europe. On June 22, 1940, France signed an armistice with Germany, which divided France between the German-occupied territory in the north and the Vichy regime in the south. Although officially neutral, the French state during this time was generally pro-Nazi and cooperated with Germany’s racial policies.
Some Auschwitz prisoners were subjected to inhumane medical experimentation. The chief perpetrator of this barbaric research was Josef Mengele (1911-79), a German physician who began working at Auschwitz in 1943. Mengele, who came to be known as the “Angel of Death,” performed a range of experiments on detainees. For example, in an effort to study eye color, he injected serum into the eyeballs of dozens of children, causing them excruciating pain. He also injected chloroform into the hearts of twins, to determine if both siblings would die at the same time and in the same manner.
Initially Göth's plan was that all the factories, including Schindler's, should be moved inside the camp gates.[52] However, Schindler, with a combination of diplomacy, flattery, and bribery, not only prevented his factory from being moved, but convinced Göth to allow him to build (at Schindler's own expense) a subcamp at Emalia to house his workers plus 450 Jews from other nearby factories. There they were safe from the threat of random execution, were well fed and housed, and were permitted to undertake religious observances.[53][54]
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]
With the deportations from Hungary, the role of Auschwitz-Birkenau in the German plan to murder the Jews of Europe achieved its highest effectiveness. Between late April and early July 1944, approximately 440,000 Jews were deported from Hungary. Of the nearly 426,000 Hungarian Jews deported to Auschwitz, approximately 320,000 of them were sent directly to the gas chambers in Auschwitz-Birkenau. They deployed approximately 110,000 at forced labor in the Auschwitz camp complex. The SS authorities transferred many of these Hungarian Jewish forced laborers within weeks of their arrival in Auschwitz to other concentration camps in Germany and Austria.
The Nazis used the phrase Lebensunwertes Leben (life unworthy of life) in reference to the disabled and mentally ill.[92] On 14 July 1933, the Law for the Prevention of Hereditarily Diseased Offspring (Gesetz zur Verhütung erbkranken Nachwuchses), the Sterilization Law, was passed, allowing for compulsory sterilization.[93][94] The New York Times reported on 21 December that year: "400,000 Germans to be sterilized".[95] There were 84,525 applications from doctors in the first year. The courts reached a decision in 64,499 of those cases; 56,244 were in favor of sterilization.[96] Estimates for the number of involuntary sterilizations during the whole of the Third Reich range from 300,000 to 400,000.[97]
To the Nazi regime, there would have been no doubt that a war against Bolshevism was implicitly a war against the Jewish population of the Soviet Union. A division of Hitler’s SS known as the Einsatzgruppen traveled behind the German army and acted as death squads, exterminating civilian populations in the most efficient way possible. During the early part of Operation Barbarossa these were frequently people who had fled the Nazi’s earlier invasion of Poland.
On 15 October 1944 a train carrying 700 men on Schindler's list was initially sent to the concentration camp at Gross-Rosen, where the men spent about a week before being re-routed to the factory in Brünnlitz.[66] Three hundred female Schindlerjuden were similarly sent to Auschwitz, where they were in imminent danger of being sent to the gas chambers. Schindler's usual connections and bribes failed to obtain their release. Finally after he sent his secretary, Hilde Albrecht, with bribes of black market goods, food and diamonds, the women were sent to Brünnlitz after several harrowing weeks in Auschwitz.[67]
Over the decades that followed, ordinary Germans struggled with the Holocaust’s bitter legacy, as survivors and the families of victims sought restitution of wealth and property confiscated during the Nazi years. Beginning in 1953, the German government made payments to individual Jews and to the Jewish people as a way of acknowledging the German people’s responsibility for the crimes committed in their name.

Those Jews selected for work were sent to a separate building for registration. Prisoners would be registered, before undressing, placing their clothes on a hook, together with their shoes. They would then be tattooed with a registration number, shaved of all body hair, disinfected and forced through showers that were either extremely cold or painfully hot.
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.
The gate house at Birkeanu is located three kilometers, or about two miles, from the main Auschwitz camp, known as Auschwitz I. To get to the Birkenau camp from the main camp, turn right after exiting from the parking lot. The road curves to the left and goes over the railroad overpass where Reichsführer Heinrich Himmler stood on March 1, 1941 when he selected the village of Birkenau to be the location of a new addition to the Auschwitz camp. At that time, the invasion of the Soviet Union and the plan to exterminate all the Jews in Europe was only months away.
The first such extermination camps were introduced during Operation Reinhardt, which targeted the elimination of the Jewish people within the General Government of Occupied Poland and Ukraine. After the first killing center open at Chelmno, the use of these extermination tactics spread quickly. At the height of deportations, the Birkenau killing center murdered 6,000 Jews a day.
The last part of an offensive operation was the destruction of un-subdued pockets of resistance, which had been enveloped earlier and by-passed by the fast-moving armoured and motorised spearheads. The Kesselschlacht 'cauldron battle' was a concentric attack on such pockets. It was here that most losses were inflicted upon the enemy, primarily through the mass capture of prisoners and weapons. During Operation Barbarossa, huge encirclements in 1941 produced nearly 3.5 million Soviet prisoners, along with masses of equipment.[66][f]
The Jews killed represented around one third of the world population of Jews,[398] and about two-thirds of European Jewry, based on an estimate of 9.7 million Jews in Europe at the start of the war.[399] Much of the uncertainty stems from the lack of a reliable figure for the number of Jews in Europe in 1939, numerous border changes that make avoiding double-counting of victims difficult, lack of accurate records from the perpetrators, and uncertainty about whether deaths occurring months after liberation, but caused by the persecution, should be counted.[392]
Fewer than 200 Jews escaped from the camps. Herman Shine, one of the last survivors to have escaped Auschwitz, died in July 2018. He was born in Berlin to a Polish father and they were arrested in that city in 1939. Along with 1,700 other Polish Jews, they were deported to Sachsenhausen. To survive, Shine claimed to be a roofer and learned how to build roofs before being transferred to Auschwitz in 1942.
Directive control was a fast and flexible method of command. Rather than receiving an explicit order, a commander would be told of his superior's intent and the role which his unit was to fill in this concept. The exact method of execution was then a matter for the low-level commander to determine as best fit the situation. Staff burden was reduced at the top and spread among commands more knowledgeable about their own situation. In addition, the encouragement of initiative at all levels aided implementation. As a result, significant decisions could be effected quickly and either verbally or with written orders a few pages in length.
When Germany invaded Poland in September 1939, it gained control of about 2 million Jews in the occupied territory. The rest of Poland was occupied by the Soviet Union, which had control of the rest of Poland's pre-war population of 3.3–3.5 million Jews.[141] German plans for Poland included expelling gentile Poles from large areas, confining Jews, and settling Germans on the emptied lands.[142] The Germans initiated a policy of sending Jews from all territories they had recently annexed (Austria, Czechoslovakia, and western Poland) to the central section of Poland, which they called the General Government. There, the Jews were concentrated in ghettos in major cities,[143] chosen for their railway lines to facilitate later deportation.[144] Food supplies were restricted, public hygiene was difficult, and the inhabitants were often subjected to forced labor.[145] In the work camps and ghettos, at least half a million Jews died of starvation, disease, and poor living conditions.[146] Jeremy Black writes that the ghettos were not intended, in 1939, as a step towards the extermination of the Jews. Instead, they were viewed as part of a policy of creating a territorial reservation to contain them.[147][l]
The Germans' overwhelming repression and the presence of many collaborators in the various local populations severely limited the ability of the Jews to resist. Jewish resistance did occur, however, in several forms. Staying alive, clean, and observing Jewish religious traditions constituted resistance under the dehumanizing conditions imposed by the Nazis. Other forms of resistance involved escape attempts from the ghettos and camps. Many who succeeded in escaping the ghettos lived in the forests and mountains in family camps and in fighting partisan units. Once free, though, the Jews had to contend with local residents and partisan groups who were often openly hostile. Jews also staged armed revolts in the ghettos of Vilna, Bialystok, Bedzin-Sosnowiec, krakow, and Warsaw.

After the arrival of a transport at the ramp in Birkenau, the process known as selection took place. SS officers decided who would be taken to work, and who would be sent directly to the gas chambers. Often it was mere chance or the mood of the SS officer that decided whether someone died immediately or had a hope of survival. The prisoners selected for slave labour were sent to one of the many auxiliary camps at Auschwitz or elsewhere in the Nazi concentration camp system. Their aim was „Vernichtung durch Arbeit“ - extermination through labour.

Even before the Nazis came to power in Germany in 1933, they had made no secret of their anti-Semitism. As early as 1919 Adolf Hitler had written, “Rational anti-Semitism, however, must lead to systematic legal opposition.…Its final objective must unswervingly be the removal of the Jews altogether.” In Mein Kampf (“My Struggle”; 1925–27), Hitler further developed the idea of the Jews as an evil race struggling for world domination. Nazi anti-Semitism was rooted in religious anti-Semitism and enhanced by political anti-Semitism. To this the Nazis added a further dimension: racial anti-Semitism. Nazi racial ideology characterized the Jews as Untermenschen (German: “subhumans”). The Nazis portrayed the Jews as a race and not as a religious group. Religious anti-Semitism could be resolved by conversion, political anti-Semitism by expulsion. Ultimately, the logic of Nazi racial anti-Semitism led to annihilation.
The PORT Technology personal transit management was invented in 2009 to remove many of the existing constraints on interior layouts, thereby allowing architects greater creative freedom when designing the next generation of buildings. The technology consists of a standalone terminal (installed on the wall or on a standalone pillar) with an LCD monitor that used to choose a floor destination, similar to the Miconic 10. PORT is the successor of Miconic 10 and Schindler ID.
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]

Blitzkrieg would not have been possible without modifying Germany's standing interwar military, which under the Treaty of Versailles was limited to 100,000 men, its air force disbanded, and tank development forbidden. After becoming head of state in 1933, Adolf Hitler ignored these provisions. A command for armored troops was created within the German Wehrmacht—the Panzertruppe, as it came to be known later. The Luftwaffe, or air force, was re-established, and development begun on ground-attack aircraft and doctrines. Hitler was a strong supporter of this new strategy. He read Guderian's book Achtung! Panzer! and upon observing armored field exercises at Kummersdorf he remarked "That is what I want—and that is what I will have."

Living standards were not high in the late 1930s. Consumption of consumer goods had fallen from 71 percent in 1928 to 59 percent in 1938. The demands of the war economy reduced the amount of spending in non-military sectors to satisfy the demand for the armed forces. On 9 September, Göring as Head of the Reich Defence Council, called for complete "employment" of living and fighting power of the national economy for the duration of the war. Overy presents this as evidence that a "blitzkrieg economy" did not exist.[133]
Birkenau was also home to two so-called family camps.  Inmates from the Czech ‘model ghetto’ Theresienstadt were deported in several transports to Birkenau, where they lived in the ‘family camp’, did not have their heads shaved, were better fed, and were freed from slave labour assignments.  They were also allowed far more freedom to create and continue the cultural production that had been the hallmark of life in Theresienstadt.  As was the case in Theresienstadt, however, this ‘generosity’ was solely for the sake of propaganda, only temporarily delaying the killing.  There was in the family camp a small musical group that was frequently required to play for the SS while they were drinking, as well as during public beatings.  Perhaps the cruellest freedom allowed the Czech camp was the freedom to educate their children.  Lessons were given in reading and counting. There were also singing and recorder lessons, with a focus on Jewish and Czech music.  In two major killing waves of March and July 1944, the Theresienstadt family camp was liquidated.
11 of Hitler’s deputies were given death sentences, including Goering, the most senior surviving Nazi. However he too committed suicide the night before he was due to hang. Others received prison terms. Albert Speer, Hitler's personal architect, was released in 1966 and spent his remaining years writing about the Nazi regime, donating most of his royalties to Jewish charities. Rudolph Hess committed suicide in prison in 1987. Many Nazis evaded justice altogether and were never tried.
Germany implemented the persecution of the Jews in stages. Following Adolf Hitler's appointment as German Chancellor in January 1933, the regime built a network of concentration camps in Germany for political opponents and those deemed "undesirable", starting with Dachau on 22 March 1933.[5] After the passing of the Enabling Act on 24 March,[6] which gave Hitler plenary powers, the government began isolating Jews from civil society, which included a boycott of Jewish businesses in April 1933 and enacting the Nuremberg Laws in September 1935. On 9–10 November 1938, during Kristallnacht (the "Night of Broken Glass"), Jewish businesses and other buildings were ransacked, smashed or set on fire throughout Germany and Austria, which Germany had annexed in March that year. After Germany invaded Poland in September 1939, triggering World War II, the regime set up ghettos to segregate Jews. Eventually thousands of camps and other detention sites were established across German-occupied Europe.
Pogroms occurred in several countries occupied by, or supportive of, Germany, attacks that were both encouraged by the Germans and carried out without their involvement.[225] Thousands of Jews were killed in January and June 1941 in the Bucharest pogrom and Iaşi pogrom in Romania, a German ally.[226] According to a 2004 report written by Tuvia Friling and others, up to 14,850 Jews died during the Iaşi pogrom.[227] The Romanian military killed up to 25,000 Jews in Odessa, then under Romanian control, between 18 October 1941 and March 1942, assisted by gendarmes and the police.[228] Mihai Antonescu, Romania's deputy prime minister, is reported as saying it was "the most favorable moment in our history" to solve the "Jewish problem".[229] In July 1941 he said it was time for "total ethnic purification, for a revision of national life, and for purging our race of all those elements which are foreign to its soul, which have grown like mistletoes and darken our future".[230]

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:
A symbol of innocence in the movie, the little girl in the red coat who appears during the liquidation of the ghetto in the movie was based on a real person. In the film, the little girl is played by actress Oliwia Dabrowska, who—at the age of three—promised Spielberg that she would not watch the film until she was 18 years old. She allegedly watched the movie when she was 11, breaking her promise, and spent years rejecting the experience. Later, she told the Daily Mail, “I realized I had been part of something I could be proud of. Spielberg was right: I had to grow up to watch the film.”

After the SS re-designated Plaszow as a concentration camp in August 1943, Schindler persuaded the SS to convert Emalia into a subcamp of Plaszow. In addition to the approximately 1,000 Jewish forced laborers registered as factory workers, Schindler permitted 450 Jews working in other nearby factories to live at Emalia as well. This saved them from the systematic brutality and arbitrary murder that was part of daily life in Plaszow.

The group raced to the English Channel, reaching the coast at Abbeville and cut off the BEF, the Belgian Army and some of the best-equipped divisions of the French Army in northern France. Armoured and motorised units under Guderian, Rommel and others, advanced far beyond the marching and horse-drawn infantry divisions and far in excess of that with which Hitler and the German high command expected or wished. When the Allies counter-attacked at Arras using the heavily armoured British Matilda I and Matilda II tanks, a brief panic was created in the German High Command. The armoured and motorised forces were halted by Hitler outside the port of Dunkirk, which was being used to evacuate the Allied forces. Hermann Göring promised that the Luftwaffe would complete the destruction of the encircled armies but aerial operations failed to prevent the evacuation of the majority of the Allied troops. In Operation Dynamo some 330,000 French and British troops escaped.[87]
Also that November, Schindler was introduced to Itzhak Stern, an accountant for Schindler's fellow Abwehr agent Josef "Sepp" Aue, who had taken over Stern's formerly Jewish-owned place of employment as a Treuhander (trustee).[21] Property belonging to Polish Jews, including their possessions, places of business, and homes were seized by the Germans beginning immediately after the invasion, and Jewish citizens were stripped of their civil rights.[22] Schindler showed Stern the balance sheet of a company he was thinking of acquiring, an enamelware factory called Rekord Ltd[a] owned by a consortium of Jewish businessmen that had filed for bankruptcy earlier that year.[23] Stern advised him that rather than running the company as a trusteeship under the auspices of the Haupttreuhandstelle Ost (Main Trustee Office for the East), he should buy or lease the business, as that would give him more freedom from the dictates of the Nazis, including the freedom to hire more Jews.[24]
