In early February, the Polish Red Cross hospital opened in blocks 14, 21, and 22 at Auschwitz I, headed by Dr. Józef Bellert and staffed by 30 volunteer doctors and nurses from Kraków, along with around 90 former inmates. The critically injured patients—estimated at several thousands—were relocated from Birkenau and Monowitz to the main camp. Some orphaned children were adopted by Oświęcim residents, while others were transferred to Kraków, where several were adopted by Polish families, or placed in an orphanage at Harbutowice.[253] The hospital cared for more than 4,500 patients (most of them Jews) from 20 countries, suffering from starvation, alimentary dystrophy, gangrene, necrosis, internal haemorrhaging, and typhoid fever. At least 500 died. Assistance was provided by volunteers from Oświęcim and Brzeszcze, who donated money and food, cleaned hospital rooms, delivered water, washed patients, cooked meals, buried the dead, and transported the sick in horse-drawn carts between locations. Securing enough food for thousands of former prisoners was a constant challenge. The hospital director personally went from village to village to collect milk.[253]
Policies differed widely among Germany’s Balkan allies. In Romania it was primarily the Romanians themselves who slaughtered the country’s Jews. Toward the end of the war, however, when the defeat of Germany was all but certain, the Romanian government found more value in living Jews who could be held for ransom or used as leverage with the West. Bulgaria deported Jews from neighbouring Thrace and Macedonia, which it occupied, but government leaders faced stiff opposition to the deportation of native Bulgarian Jews, who were regarded as fellow citizens.
In 2017 a Körber Foundation survey found that 40 percent of 14-year-olds in Germany did not know what Auschwitz was.[280][281] The following year a survey organized by the Claims Conference, United States Holocaust Memorial Museum and others found that 41 percent of 1,350 American adults surveyed, and 66 percent of millennials, did not know what Auschwitz was, while 22 percent said they had never heard of the Holocaust.[282] A CNN-ComRes poll in 2018 found a similar situation in Europe.[283]
Blitzkrieg   (German, literally lightning war or flash war) is a popular name for an offensive operational-level military doctrine which involves an initial bombardment followed by employment of mobile forces attacking with speed and surprise to prevent an enemy from implementing a coherent defense. The founding principles of these types of operations were developed in the 19th Century by various nations, and adapted in the years after World War I, largely by the German Wehrmacht, to incorporate modern weapons and vehicles as a method to help prevent trench warfare and linear warfare in future conflicts. The first practical implementations of these concepts coupled with modern technology were instituted by the Wehrmacht in the opening battles of World War II. While operations in Poland were rather conventional, subsequent battles — particularly the invasions of France, The Netherlands and initial operations in the Soviet Union — were effective owing to surprise penetrations, general enemy unpreparedness and an inability to react swiftly enough to German offensive operations. That the German Army quickly defeated numerically and technically superior enemies in France led many analysts to believe that a new system of warfare had been invented.

The soldiers also found warehouses containing 836,525 items of women clothing, 348,820 items of men clothing, 43,525 pairs of shoes and vast numbers of toothbrushes, glasses and other personal effects. They found also 460 artificial limbs and seven tons of human hair shaved from Jews before they were murdered. The human hairs were used by the company “Alex Zink” (located in Bavaria) for confection of cloth. This company was paying the Nazi’s 50 pfennig per kilo of human hair.

In reality, the way in which the Wehrmacht fought, their 'doctrine' in today's parlance, was based more upon ideas than technology. And the ideas that shaped how Hitler's army fought were influenced by the fighting methods German soldiers had used since the 1870s. The so-called blitzkrieg of 1940 was really the German doctrine of 1914 with technology bolted on.
Auschwitz, the largest and arguably the most notorious of all the Nazi death camps, opened in the spring of 1940. Its first commandant was Rudolf Höss (1900-47), who previously had helped run the Sachsenhausen concentration camp in Oranienburg, Germany. Auschwitz was located on a former military base outside OÅ›wiÄ™cim, a town in southern Poland situated near Krakow, one of the country’s largest cities. During the camp’s construction, nearby factories were appropriated and all those living in the area were forcibly ejected from their homes, which were bulldozed by the Nazis.
A parallel system operated later at Birkenau in 1942-43, except that for the majority the 'showers' proved to be gas chambers. Only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the 'central sauna' before being assigned barracks. In May 1944, a spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944.
^ These are some of the many notable historians that have casually used the term blitzkrieg—including some who have written on its misconception—to describe several Wehrmacht military operations that were spearheaded by a dense concentration of armoured and motorised formations with the aim of delivering a breakthrough, and exploiting it with speed to paralyse and encircle the enemy: David Glantz (Glantz 2010, p. 14; Glantz 2009, p. 164; Glantz 2001), Jonathan House (Glantz & House 1999, pp. 254, 269; Glantz & House 1995, pp. 61, 125, 167, 226, 274, 286, 288), Lloyd Clark (Clark 2012, pp. 22–27, 187), Antony Beevor (Beevor 1999, pp. 13, 148; Beevor 2006, p. 157), Mungo Melvin (Melvin 2011, pp. 46, 79–80, 199), John Erickson (Erickson 2001, pp. 558, 567) and Steven Mercatante (Mercatante 2012, pp. 65, 77, 91, 301).
Sanitary facilities for prisoners at Auschwitz-Birkenau were extremely poor. It was impossible for inmates to keep clean or have a change of clothes.  For the first two years of the camp’s existence, the prisoners had no access to water for washing. When there was later water, it was not clean. Prisoners, therefore, spent their existence in the camp dirty and in filthy clothes, which increased the likelihood of them contracting infections and diseases.

^ Some of the military historians who consider Operation Citadel, or at least the southern pincer, as envisioning a blitzkrieg attack or state it was intended as such are: Lloyd Clark (Clark 2012, p. 187), Roger Moorhouse (Moorhouse 2011, p. 342), Mary Kathryn Barbier (Barbier 2002, p. 10), David Glantz (; Glantz & House 2004, pp. 63, 78, 149, 269, 272, 280), Jonathan House (Glantz & House 2004, pp. 63, 78, 149, 269, 272, 280), Hedley Paul Willmott (Willmott 1990, p. 300), Oscar Pinkus (Pinkus 2005, p. 35) and others.

Political dissidents, trade unionists, and Social Democrats were among the first to be arrested and incarcerated in concentration camps. Under the Weimar government, centuries-old prohibitions against homosexuality had been overlooked, but this tolerance ended violently when the SA (Storm Troopers) began raiding gay bars in 1933. Homosexual intent became just cause for prosecution. The Nazis arrested German and Austrian male homosexuals—there was no systematic persecution of lesbians—and interned them in concentration camps, where they were forced to wear special yellow armbands and later pink triangles. The goal of persecuting male homosexuals was either for reeducation—what might now be called conversion therapy—or punishment. Jehovah’s Witnesses were a problem for the Nazis because they refused to swear allegiance to the state, register for the draft, or utter the words “Heil Hitler.” As a result, the Nazis imprisoned many of the roughly 20,000 Jehovah’s Witnesses in Germany. They could be released from concentration camps if they signed a document renouncing their faith and promising not to proselytize. Few availed themselves of that option, preferring martyrdom to apostasy. Germans of African descent—many of whom, called “Rhineland bastards” by the Nazis, were the offspring of German mothers and French colonial African troops who had occupied the Rhineland after World War I—were also persecuted by the Nazis. Although their victimization was less systematic, it included forced sterilization and, often, internment in concentration camps. The fear was that they would “further pollute” and thereby diminish the race. The Nazis also singled out the Roma and Sinti, pejoratively known as Gypsies. They were the only other group that the Nazis systematically killed in gas chambers alongside the Jews. For the Roma and Sinti, too, racial pollution and their depiction as asocials was the justification for their persecution and murder.

Eventually, Birkenau held the majority of prisoners in the Auschwitz complex, including Jews, Poles, Germans, and Gypsies. Furthermore, it maintained the most degrading and inhumane conditions–inclusive of the complex’s gas chambers and crematoria. A third section, Auschwitz III, was constructed in nearby Monowitz, and consisted of a forced labor camp called Buna-Monowitz.
The prisoners put up various forms of resistance to the tyranny of the camp. Resistance organisations helped inmates to obtain medicine and food, documented Nazi crimes, supported attempts to escape and sabotage, tried to put political prisoners into positions of responsibility, and prepared for an uprising. A total of 667 prisoners escaped from Auschwitz, but 270 of them were caught in the vicinity of the camp and immediately executed. The best-known escape was that of two Slovak Jews, Alfred Wetzler and Walter Rosenberg (Rudolf Vrba) (link in Czech). They managed to cross into Slovakia and to tell Jewish leaders - and through them the world - about the terrible reality of Auschwitz, about which they wrote an extensive report. On the 7th of October 1944, there was an uprising by the Sonderkommando working in the gas chambers. The prisoners managed to destroy one of the gas chambers, and thus to hinder the extermination process. All the rebels died. A group of young female prisoners was also executed for having smuggled gunpowder to the rebels from the factory in Monowitz.
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 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.
Beginning in late 1941, the Germans began mass transports from the ghettoes in Poland to the concentration camps, starting with those people viewed as the least useful: the sick, old and weak and the very young. The first mass gassings began at the camp of Belzec, near Lublin, on March 17, 1942. Five more mass killing centers were built at camps in occupied Poland, including Chelmno, Sobibor, Treblinka, Majdanek and the largest of all, Auschwitz-Birkenau. From 1942 to 1945, Jews were deported to the camps from all over Europe, including German-controlled territory as well as those countries allied with Germany. The heaviest deportations took place during the summer and fall of 1942, when more than 300,000 people were deported from the Warsaw ghetto alone.
German communists, socialists and trade unionists were among the earliest opponents of the Nazis[443] and among the first to be sent to concentration camps.[444] Before the invasion of the Soviet Union, Hitler issued the Commissar Order, which ordered the execution of all political commissars and Communist Party members captured.[445] Nacht und Nebel ("Night and Fog") was a directive of Hitler in December 1941, resulting in the disappearance of political activists throughout the German-occupied territories.[446]
Auschwitz II, located in the village of Birkenau, or Brzezinka, just outside OÅ›wiÄ™cim, was constructed in 1941 on the order of Heinrich Himmler (1900-45), commander of the “Schutzstaffel” (or Select Guard/Protection Squad, more commonly known as the SS), which operated all Nazi concentration camps and death camps. Birkenau, the biggest of the Auschwitz facilities, could hold some 90,000 prisoners. It also housed a group of bathhouses where countless people were gassed to death, and crematory ovens where bodies were burned. The majority of Auschwitz victims died at Birkenau.More than 40 smaller facilities, called subcamps, dotted the landscape and served as slave-labor camps. The largest of these subcamps, Monowitz, also known as Auschwitz III, began operating in 1942 and housed some 10,000 prisoners.

In Birkenau, which was built anew on the site of a displaced village, only a small number of historic buildings have survived. Due to the method used in constructing those buildings, planned as temporary structures and erected in a hurry using demolition materials, the natural degradation processes have been accelerating. All efforts are nevertheless being taken to preserve them, strengthen their original fabric and protect them from decay.
In 1944, Plaszow transitioned from a labor camp to a concentration camp and all Jews were to be sent to the death camp at Auschwitz. Schindler requested Göth allow him to relocate his factory to Brnĕnec, in the Sudetenland, and produce war goods. He was told to draw up a list of workers he wanted to take with him. With Stern’s help, Schindler created a list of 1,100 Jewish names he deemed “essential” for the new factory. Permission was granted and the factory was moved. Not wanting to contribute to the German war effort, Schindler ordered his workers to purposefully make defective products that would fail inspection. The employees spent the remaining months of the war in the factory.
The Nuremberg Laws, issued on Sept. 15, 1935, was designed to exclude Jews from public life. The Nuremberg Laws stripped German Jews of their citizenship and prohibited marriages and extramarital sex between Jews and Gentiles. These measures set the legal precedent for anti-Jewish legislation that followed. Nazis issued numerous anti-Jewish laws over the next several years. Jews were banned from public parks, fired from civil service jobs, and forced to register their property. Other laws barred Jewish doctors from treating anyone other than Jewish patients, expelled Jewish children from public schools, and placed severe travel restrictions on Jews.
Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]
Blitzkrieg (German: "lightning war") is a method of fast-moving, air-and-land warfare first used extensively during World War II. German armies invading Poland in 1939 used tanks, armored trucks, self-propelled guns, and dive bombers to break through opposing forces and penetrate far behind their lines. During the invasion of the Low Countries and France in 1940, the German armored columns again used these tactics to shock and disorganize the defenders. On the Allied side, U.S. general George S. Patton exhibited (1944) particular skill in mobile warfare in Europe.
The government defined a Jewish person as someone with three or four Jewish grandparents, not someone who had religious convictions. This meant that people who had never practiced, or hadn’t practiced Judaism in many years, or even converted to Christianity were subjected to persecution. Although anti-semitism was pervasive in 1930s Germany, these restrictions frequently extended to any person the Nazis considered to be “non-Aryan”.
In nearly every country overrun by the Nazis, the Jews were forced to wear badges marking them as Jews, they were rounded up into ghettos or concentration camps and then gradually transported to the killing centers. The death camps were essentially factories for murdering Jews. The Germans shipped thousands of Jews to them each day. Within a few hours of their arrival, the Jews had been stripped of their possessions and valuables, gassed to death, and their bodies burned in specially designed crematoriums. Approximately 3.5 million Jews were murdered in these death camps.
Oskar Schindler renamed the factory Deutsche Emaillewaren-Fabrik (German Enamelware Factory) and started production with a small staff. Possessing a certain panache for business and engaging in influence peddling, Schindler secured numerous German army contracts for kitchenware. He soon met Itzhak Stern, a Jewish accountant, who connected Schindler with Krakow’s Jewish community to staff the factory.
^ After the invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory.[147][148][149] Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation.[150] Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April.[151] By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau.[152] Resettlement continued until January 1941 under Odilo Globocnik,[153] and included both Jews and Poles.[154] By that time 95,000 Jews were already concentrated in the area,[155] but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.[156]
Having achieved a breakthrough into the enemy's rear areas, German forces attempted to paralyze the enemy's decision making and implementation process. Moving faster than enemy forces, mobile forces exploited weaknesses and acted before opposing forces could formulate a response. Guderian wrote that "Success must be exploited without respite and with every ounce of strength, even by night. The defeated enemy must be given no peace."
Marked by fierce close quarters combat and direct assaults on civilians in air raids, it is often regarded as the single largest (nearly 2.2 million personnel) and bloodiest (1.8–2 million killed, wounded or captured) battle in the history of warfare. It was an extremely costly defeat for German forces, and the Army High Command had to withdraw vast military forces from the West to replace their losses.
When he learned what had happened, Schindler at first managed to secure the release of the men from the Gross-Rosen camp.  He then proceeded to send his personal German secretary to Auschwitz to negotiate the release of the women. The latter managed to obtain the release of the Jewish women by promising to pay 7 RM daily per worker. This is the only recorded case in the history of the extermination camp that such a large group of people were allowed to leave alive while the gas chambers were still in operation.
The education system in America does a very good job regarding the issue of WW2. I think the problem with some American student is that there is still a very deep rooted assumption that this kind of thing could never happen on our soil. Even with the civil war and slave history in this country, people fail to look for similarites in experience. The more people focus on the difference between us and them, the less likely one is to truly undertand HOW such history CAN happen.

Throughout the Middle Ages in Europe, Jews were subjected to antisemitism based on Christian theology, which blamed them for killing Jesus. Even after the Reformation, Catholicism and Lutheranism continued to persecute Jews, accusing them of blood libels and subjecting them to pogroms and expulsions.[60][61] The second half of the 19th century saw the emergence in the German empire and Austria-Hungary of the völkisch movement, which was developed by such thinkers as Houston Stewart Chamberlain and Paul de Lagarde. The movement embraced a pseudo-scientific racism that viewed Jews as a race whose members were locked in mortal combat with the Aryan race for world domination.[62] These ideas became commonplace throughout Germany,[63] with the professional classes adopting an ideology that did not see humans as racial equals with equal hereditary value.[64] Although the völkisch parties had support in elections at first, by 1914 they were no longer influential. This did not mean that antisemitism had disappeared; instead it was incorporated into the platforms of several mainstream political parties.[63]

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]
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]

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]
