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:
Auschwitz was probably chosen to play a central role in the “final solution” because it was located at a railway junction with 44 parallel tracks—rail lines that were used to transport Jews from throughout Europe to their death. Heinrich Himmler, chief of the SS, the Nazi paramilitary corps, ordered the establishment of the first camp, the prison camp, on April 27, 1940, and the first transport of Polish political prisoners arrived on June 14. This small camp, Auschwitz I, was reserved throughout its history for political prisoners, mainly Poles and Germans.
Please remember that you are essentially visiting a mass grave site, as well as a site that has an almost incalculable meaning to a significant portion of the world's population. There are still many men and women alive who survived their time here, and many more who had loved ones who were murdered or worked to death there, Jews and non-Jews alike. Please treat the site with all of the dignity, solemnity and respect it deserves. Do not make jokes about the Holocaust or Nazis. Do not deface the site by marking or scratching graffiti into structures. Do not take anything from the camp area with you "as a souvenir", and do not make Nazi salutes, even jokingly — these are considered offences under Polish law, and if you commit them, you will be placed before the court and could be subjected to a prison sentence of up to two years for propagating fascism. Pictures are permitted in outdoor areas, but remember this is a memorial rather than a tourist attraction, and there will undoubtedly be visitors who have a personal connection with the camps, so be discreet with cameras.

Auschwitz, perhaps the most notorious and lethal of the concentration camps, was actually three camps in one: a prison camp (Auschwitz I), an extermination camp (Auschwitz II–Birkenau), and a slave labour camp (Auschwitz III–Buna-Monowitz). Upon arrival, Jewish prisoners faced what was called a Selektion. A German doctor presided over the selection of pregnant women, young children, the elderly, handicapped, sick, and infirm for immediate death in the gas chambers. As necessary, the Germans selected able-bodied prisoners for forced labour in the factories adjacent to Auschwitz, where one German company, IG Farben, invested 700 million Reichsmarks in 1942 alone to take advantage of forced labour, a capital investment. The conglomerate presumed that slave labour would be a permanent part of the German economy. Deprived of adequate food, shelter, clothing, and medical care, these prisoners were literally worked to death. Periodically, they would face another Selektion. The Nazis would transfer those unable to work to the gas chambers of Birkenau.
Innovators such as Heinz Guderian and Erich von Manstein recognised that the protection given by tanks increased the ability of the German army to manoeuvre in the face of enemy artillery, and that this enhanced speed and mobility. However, the modern technology was merely used to enhance the capabilities that had already been provided, thanks to the army's strategic doctrine.
I have been to Dachau and Auschwitz and as sad as it is to see the movies and books, it is a much sadder reality to see these attrocities up close. Anyone who does not believe that this unhuman behaviour(idiot guy from last post!) took place should take a closer look at their education and spoiled life today in comparison to how it was back then to fear your life every day. It wasn't just jews and religion shouldn't have mattered,but it did. It was human beings been murdered out of pure blind hatred and ignorance.
On January 20, 1942, several top officials of the German government met to officially coordinate the military and civilian administrative branches of the Nazi system to organize a system of mass murder of the Jews. This meeting, called the Wannsee Conference, "marked the beinning of the full-scale, comprehensive extermination operation [of the Jews] and laid the foundations for its organization, which started immediately after the conference ended" (Yahil, The Holocaust, p. 318).
The concept of blitzkrieg was formed by Prussian military tactics of the early 19th century, which recognized that victory could come only through forceful and swift action because of Prussia’s relatively limited economic resources. It had its origins with the Schwerpunktprinzip (“concentration principle”) proposed by Carl von Clausewitz in his seminal work On War (1832). Having studied generals who predated Napoleon, Clausewitz found that commanders of various armies had dispersed their forces without focused reasoning, which resulted in those forces’ being used inefficiently. So as to eliminate that wasteful use of manpower, he advocated for a concentration of force against an enemy. All employment of force should have an effective concentration in a single moment, with a single action, Clausewitz argued. Clausewitz called that concentration the Schwerpunkt (“centre of gravity”) where it was most dense, identifying it as the effective target for attack.
Several protective zones surround components of the World Heritage property and function de facto as buffer zones. They are covered by local spatial development plans, which are consulted by the Regional Monuments Inspector. The management of the property’s setting is the responsibility of the local government of the Town and Commune of Oświęcim. For better management and protection of the attributes of the Outstanding Universal Value of the property, especially for the proper protection of its setting, a relevant management plan must be put into force.
Despite the continuing war with Great Britain, German forces invaded the Soviet Union in June 1941. At first, the German Blitzkrieg seemed to succeed. Soviet forces were driven back more than 600 miles to the gates of Moscow, with staggering losses. In December 1941, Hitler unilaterally declared war on the United States, which consequently added its tremendous economic and military power to the coalition arrayed against him. A second German offensive against the Soviet Union in 1942 brought German forces in the east to the shores of the Volga River and the city of Stalingrad. However, the Soviet Union launched a counteroffensive in November 1942, trapping and destroying an entire German army at Stalingrad.
Adam Tooze wrote that the German economy was being prepared for a long war. The expenditure for this war was extensive and put the economy under severe strain. The German leadership were concerned less with how to balance the civilian economy and the needs of civilian consumption but to figure out how to best prepare the economy for total war. Once war had begun, Hitler urged his economic experts to abandon caution and expend all available resources on the war effort but the expansion plans only gradually gained momentum in 1941. Tooze wrote that the huge armament plans in the pre-war period did not indicate any clear-sighted blitzkrieg economy or strategy.[134]

Revisionism must not be taken to extremes. German operational successes in the early years of World War II were by no means the product of sheer good fortune. But neither did they reflect a coherent, planned approach to the diplomatic, economic, and military challenges that after 1918 confronted a state unwilling to accept the consequences of its defeat in World War I. What are commonly called blitzkrieg operations developed out of experiences gained on the field between 1939 to 1941. In that sense blitzkrieg is best understood as a post facto construction for explaining a complex structure of events and ideas.

On the Eastern Front, the war did not bog down into trench warfare; German and Russian armies fought a war of manoeuvre over thousands of miles, which gave the German leadership unique experience not available to the trench-bound western Allies.[30] Studies of operations in the east led to the conclusion that small and coordinated forces possessed more combat power than large, uncoordinated forces. After the war, the Reichswehr expanded and improved infiltration tactics. The commander in chief, Hans von Seeckt, argued that there had been an excessive focus on encirclement and emphasized speed instead.[31] Seeckt inspired a revision of Bewegungskrieg (maneuver warfare) thinking and its associated Auftragstaktik, in which the commander expressed his goals to subordinates and gave them discretion in how to achieve them; the governing principle was "the higher the authority, the more general the orders were", so it was the responsibility of the lower echelons to fill in the details.[32] Implementation of higher orders remained within limits determined by the training doctrine of an elite officer-corps.[33] Delegation of authority to local commanders increased the tempo of operations, which had great influence on the success of German armies in the early war period. Seeckt, who believed in the Prussian tradition of mobility, developed the German army into a mobile force, advocating technical advances that would lead to a qualitative improvement of its forces and better coordination between motorized infantry, tanks, and planes.[34]
Infiltration tactics invented by the German Army during the First World War became the basis for later tactics. German infantry had advanced in small, decentralised groups which bypassed resistance in favour of advancing at weak points and attacking rear-area communications. This was aided by co-ordinated artillery and air bombardments, and followed by larger infantry forces with heavy guns, which destroyed centres of resistance. These concepts formed the basis of the Wehrmacht's tactics during the Second World War.

From this moment on, the Nazi regime adopted hundreds of laws restricting the rights and liberties of the Jewish people. Jews were expelled from the civil service and barred from entering particular professions, stripped of their citizenship, and forbidden from intermarrying or even having a relationship with anyone of “German or German-related blood”.
Blitzkrieg, as practiced by the Wehrmacht during World War II, was a tactical action executed with extreme competence. It involved the coordination of all forces and it had a very small margin of error. But this coordination that made it such a successful tactic is the main thing missed when Blitzkrieg is referenced in day-to-day conversations that focus only on the speed by which a certain position is secured. All the other items we discussed (initiative, focus and tempo) fall apart without this synchronization.
Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million.[400] Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories.[401][402] Of Poland's 3.3 million Jews, about 90 percent were killed.[369] Many more died in the ghettos of Poland before they could be deported.[403] The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews.[394] At Auschwitz-Birkenau the Jewish death toll was 1.1 million;[286][404] Treblinka 870,000–925,000;[405] Bełżec 434,000–600,000;[406][287] Chełmno 152,000–320,000;[407][288] Sobibór 170,000–250,000;[408][291] and Majdanek 79,000.[289]
The impact of the Holocaust varied from region to region and from year to year in the 21 countries that were directly affected. Nowhere was the Holocaust more intense and sudden than in Hungary. What took place over several years in Germany occurred over 16 weeks in Hungary. Entering the war as a German ally, Hungary had persecuted its Jews but not permitted the deportation of Hungarian citizens. In 1941 foreign Jewish refugees were deported from Hungary and were shot by Germans in Kam’yanets-Podilskyy, Ukraine. After Germany invaded Hungary on March 19, 1944, the situation changed dramatically. By mid-April the Nazis had confined Jews to ghettos. On May 15, deportations began, and over the next 55 days the Nazis deported more than 437,000 Jews from Hungary to Auschwitz on 147 trains.
Voldemort coming back was always a lingering danger in the early Harry Potter books and movies, as fans waited eagerly to see the Dark Lord reborn and return to full power. It was definitely worth the wait when we were finally able to watch Voldemort return toward the end of Harry Potter and the Goblet of Fire, the fourth book—and movie—in the series.
The roots of Hitler’s particularly virulent brand of anti-Semitism are unclear. Born in Austria in 1889, he served in the German army during World War I. Like many anti-Semites in Germany, he blamed the Jews for the country’s defeat in 1918. Soon after the war ended, Hitler joined the National German Workers’ Party, which became the National Socialist German Workers’ Party (NSDAP), known to English speakers as the Nazis. While imprisoned for treason for his role in the Beer Hall Putsch of 1923, Hitler wrote the memoir and propaganda tract “Mein Kampf”(My Struggle), in which he predicted a general European war that would result in “the extermination of the Jewish race in Germany.”

Shipments of Jews to the camps had priority over anything but the army's needs on the German railways, and continued even in the face of the increasingly dire military situation at the end of 1942.[355] Army leaders and economic managers complained about this diversion of resources and the killing of skilled Jewish workers,[356] but Nazi leaders rated ideological imperatives above economic considerations.[357]

Auschwitz became one of the camps used for the mass extermination of Jews. In summer 1941, Heinrich Himmler gave orders to Auschwitz commander Rudolf Höß to build a centre at Auschwitz for the mass murder of Jews. In September 1941, the lethal effects of Zyklon B - a substance normally used for pest control - were first tested and verified there. Later, four large gas chambers were built at Birkenau, capable of killing up to six thousand people each day. The gas chambers were disguised as showers, meant to persuade the victims that these were disinfection measures which they had to undergo before they were sent to work in the camp.

In order to protect the tanks, and secure the areas penetrated by the German army, motorized infantry would accompany tanks into battle. The Germans believed the only way to defeat an enemy force was to cut it off. Cutting it off required superior mobility relative to the enemy force. The introduction of mechanical means on the battlefield provided the Germans the answer to the deadlocks common in WWI. Tanks and other armored vehicles gave the German Army the ability to force the enemy to react to their new found mobility.
Peter Hayes (How Was It Possible? A Holocaust Reader, 2015): "The Holocaust, the Nazi attempt to eradicate the Jews of Europe, has come to be regarded as the emblematic event of Twentieth Century ... Hitler's ideology depicted the Jews as uniquely dangerous to Germany and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it. The threat posted by supposedly corrupting but generally powerless Sinti and Roma was far less, and therefore addressed inconsistently in the Nazi realm. Gay men were defined as a problem only if they were German or having sex with Germans or having sex with Germans and considered 'curable' in most cases. ... Germany's murderous intent toward the handicapped inhabitants of European mental institutions ... was more comprehensive ... but here, too, implementation was uneven and life-saving exceptions permitted, especially in Western Europe. Not only were some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—allotted a favored place in Hitler's New Order, but the fate of most of the other Slavs the Nazis derided as sub-humans ... consisted of enslavement and gradual attrition, not the prompt massacre meted out to the Jews after 1941."[20]
The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as millions of others, including Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler’s “final solution”–now known as the Holocaust–came to fruition under the cover of world war, with mass killing centers constructed in the concentration camps of occupied Poland.
The biggest mistakes made by most companies is that they have just one department (usually product and engineering) that puts Blitzkrieg tactics into practice. Most development teams now operate in sprints, deliver incremental customer value and use estimation methods to frequently update plans. However, very few companies have marketing or sales departments mirroring these methods, which leads to having parts of companies operating out-of-sync, at different paces and on disparate roadmaps. As demonstrated by the Germans during WWII, synchronization acts like a force multiplier, and today it can make the difference for companies competing in crowded markets.
Use of bunkers I and 2 stopped in spring 1943 when the new crematoria were built, although bunker 2 became operational again in May 1944 for the murder of the Hungarian Jews.[47] Crematorium II, which had been designed as a mortuary with morgues in the basement and ground-level incinerators, was converted by installing gas-tight doors, vents for the Zyklon B to be dropped into the chamber, and ventilation equipment to remove the gas thereafter.[48] It went into operation in March 1943. Crematorium III was built using the same design. Crematoria IV and V, designed from the start as gassing centers, were also constructed that spring. By June 1943, all four crematoria were operational. Most of the victims were killed using these four structures.[49]

The people in the houses were rudely awoken by the din of our tanks, the clatter and roar of tracks and engines. Troops lay bivouacked beside the road, military vehicles stood parked in farmyards and in some places on the road itself. Civilians and French troops, their faces distorted with terror, lay huddled in the ditches, alongside hedges and in every hollow beside the road. We passed refugee columns, the carts abandoned by their owners, who had fled in panic into the fields. On we went, at a steady speed, towards our objective. Every so often a quick glance at the map by a shaded light and a short wireless message to Divisional H.Q. to report the position and thus the success of 25th Panzer Regiment. Every so often a look out of the hatch to assure myself that there was still no resistance and that contact was being maintained to the rear. The flat countryside lay spread out around us under the cold light of the moon. We were through the Maginot Line! It was hardly conceivable. Twenty-two years before we had stood for four and a half long years before this self-same enemy and had won victory after victory and yet finally lost the war. And now we had broken through the renowned Maginot Line and were driving deep into enemy territory. It was not just a beautiful dream. It was reality."
As Nazi tyranny spread across Europe, the Germans and their collaborators persecuted and murdered millions of other people. Between two and three million Soviet prisoners of war were murdered or died of starvation, disease, neglect, or brutal treatment. The Germans targeted the non-Jewish Polish intelligentsia for killing, and deported millions of Polish and Soviet civilians for forced labor in Germany or in occupied Poland, where these individuals worked and often died under deplorable conditions.
The period between Germany's defeat of Poland in October 1939 and her invasion of Norway in April 1940 is often referred to as the "Phony War." Not much happened. The French stiffened their defenses while the British moved troops to the continent. The British wanted to send their air force to bomb targets inside Germany but were persuaded not to by the French who feared German reprisal. The major activity consisted of dueling propaganda messages blared from loud speakers across the German and French lines.
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.
In the course of the war, the camp was staffed by 7,000 members of the German Schutzstaffel (SS), approximately 12 percent of whom were later convicted of war crimes. Several, including camp commandant Rudolf Höss, were executed. The Allies did not act on early reports of atrocities at the camp, and their failure to bomb the camp or its railways remains controversial. At least 802 prisoners tried to escape from Auschwitz, 144 successfully, and on 7 October 1944 two Sonderkommando units, consisting of prisoners assigned to staff the gas chambers, launched a brief, unsuccessful uprising.

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]
You find gripping and horrifying stories of Adolf Hitler and his most ruthless henchmen - men often seen as the very personifications of evil, like Rudolf Hoess, the SS Commandant of Auschwitz, the Nazi butcher Amon Goeth at Plaszow and Josef Mengele, The Angel Of Death. You may read about Hitler's wife, Eva Braun, or Admiral Wilhelm Canaris, Chief of the German Military Intelligence who was a dedicated anti-Nazi and held Hitler in utter contempt. He tried to put a stop to the crimes of war and genocide committed by the Nazis.

As the tide of World War II turned against the Nazis, they began a systematic plan to eliminate or "liquidate" the ghettos they had established, by a combination of mass murder on the spot and transferring the remaining residents to extermination camps. When the Nazis attempted to liquidate the Warsaw Ghetto on April 13, 1943, the remaining Jews fought back in what has become known as the Warsaw Ghetto Uprising. The Jewish resistance fighters held out against the entire Nazi regime for 28 days, longer than many European countries had been able to withstand Nazi conquest.
The Gestapo arrested him several times and interrogated him on charges of irregularities and of favoring Jews. However, Schindler would not desist. In 1943, at the invitation of the American Jewish Joint Distribution Committee, he undertook a highly risky journey to Budapest, where he met with two representatives of Hungarian Jewry. He reported to them about the desperate plight of the Jews in Poland and discussed possible ways of relief.
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.
Jewish deportees arriving at Auschwitz-Birkenau immediately underwent selection. The SS staff chose some of the able-bodied for forced labor and sent the rest directly to the gas chambers, which were disguised as shower installations to mislead the victims. The belongings of all deportees were confiscated and sorted in the "Kanada" (Canada) warehouse for shipment back to Germany. Canada symbolized wealth to the prisoners.
On 2 July 1947, the Polish government passed a law establishing a state memorial to remember "the martyrdom of the Polish nation and other nations in Oswiecim".[284] The museum established its exhibits at Auschwitz I; after the war, the barracks in Auschwitz II-Birkenau had been mostly dismantled and moved to Warsaw to be used on building sites. Dwork and van Pelt write that, in addition, Auschwitz I played a more central role in the persecution of the Polish people, in opposition to the importance of Auschwitz II to the Jews, including Polish Jews.[285] An exhibition opened in Auschwitz I in 1955, displaying prisoner mug shots; hair, suitcases, and shoes taken from murdered prisoners; canisters of Zyklon B pellets; and other objects related to the killings.[286] UNESCO added the camp to its list of World Heritage Sites in 1979.[287] All the museum's directors were, until 1990, former Auschwitz prisoners. Visitors to the site have increased from 492,500 in 2001, to over one million in 2009,[288] to two million in 2016.[289]
Up to this point, Auschwitz accounted for only 11 percent of the victims of the 'Final Solution'. However, in August 1942, planning began for the construction of four large-scale gassing facilities. It appears from the plans that the first two gas chambers were adapted from mortuaries which, with the huge crematoria attached to them, were initially intended to cope with mortalities amongst the slave labor force in the camp, now approaching 100,000 and subject to a horrifying death rate. But from the autumn of 1942, it seems clear that the SS planners and civilian contractors were intending to build a mass-murder plant.
German military history had been influenced heavily by Carl von Clausewitz, Alfred von Schlieffen and von Moltke the Elder, who were proponents of maneuver, mass, and envelopment. Their concepts were employed in the successful Franco-Prussian War and attempted "knock-out blow" of the Schlieffen Plan. Following the war, these concepts were modified by the Reichswehr. Its Chief of Staff, Hans von Seeckt, moved doctrine away from what he argued was an excessive focus on encirclement towards one based on speed. Speed gives surprise, surprise allows exploitation if decisions can be reached quickly and mobility gives flexibility and speed. Von Seeckt advocated effecting breakthroughs against the enemy's centre when it was more profitable than encirclement or where encirclement was not practical. Under his command a modern update of the doctrinal system called "Bewegungskrieg" and its associated tactical system called " Auftragstaktik" was developed which resulted in the popularly known blitzkrieg effect. He additionally rejected the notion of mass which von Schlieffen and von Moltke had advocated. While reserves had comprised up to four-tenths of German forces in pre-war campaigns, von Seeckt sought the creation of a small, professional (volunteer) military backed by a defense-oriented militia. In modern warfare, he argued, such a force was more capable of offensive action, faster to ready, and less expensive to equip with more modern weapons. The Reichswehr was forced to adopt a small and professional army quite aside from any German plans, for the Treaty of Versailles limited it to 100,000 men.

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 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.
Throughout the spring and summer of 1940, the German army expanded Hitler’s empire in Europe, conquering Denmark, Norway, the Netherlands, Belgium, Luxembourg and France. Beginning in 1941, Jews from all over the continent, as well as hundreds of thousands of European Gypsies, were transported to the Polish ghettoes. The German invasion of the Soviet Union in June 1941 marked a new level of brutality in warfare. Mobile killing units called Einsatzgruppenwould murder more than 500,000 Soviet Jews and others (usually by shooting) over the course of the German occupation.

Oskar Schindler, (born April 28, 1908, Svitavy [Zwittau], Moravia, Austria-Hungary [now in the Czech Republic]—died October 9, 1974, Hildesheim, West Germany), German industrialist who, aided by his wife and staff, sheltered approximately 1,100 Jews from the Nazis by employing them in his factories, which supplied the German army during World War II.
On 15 September 1935, the Reichstag passed the Reich Citizenship Law and the Law for the Protection of German Blood and German Honor, known as the Nuremberg Laws. The former said that only those of "German or kindred blood" could be citizens. Anyone with three or more Jewish grandparents was classified as a Jew.[107] The second law said: "Marriages between Jews and subjects of the state of German or related blood are forbidden." Sexual relationships between them were also criminalized; Jews were not allowed to employ German women under the age of 45 in their homes.[108] The laws referred to Jews but applied equally to the Roma and black Germans.[107]

The Auschwitz registry (Hauptbücher) shows that 20,946 Roma were registered prisoners,[145] and another 3,000 are thought to have entered unregistered.[146] On 22 March 1943, one transport of 1,700 Polish Sinti and Roma was gassed on arrival because of illness, as was a second group of 1,035 on 25 May 1943.[145] The SS tried to liquidate the camp on 16 May 1944, but the Roma fought them, armed with knives and iron pipes, and the SS retreated. Shortly after this, the SS removed nearly 2,908 from the family camp to work, and on 2 August 1944 gassed the other 2,897. Ten thousand remain unaccounted for.[147]

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."
Schindler's ties with the Abwehr and his connections in the Wehrmacht and its Armaments Inspectorate enabled him to obtain contracts to produce enamel cookware for the military.[31] These connections also later helped him protect his Jewish workers from deportation and death.[32] As time went on, Schindler had to give Nazi officials ever larger bribes and gifts of luxury items obtainable only on the black market to keep his workers safe.[33] Bankier, a key black market connection, obtained goods for bribes as well as extra materials for use in the factory.[34] Schindler himself enjoyed a lavish lifestyle and pursued extramarital relationships with his secretary, Viktoria Klonowska, and Eva Kisch Scheuer, a merchant specialising in enamelware from DEF.[35] Emilie Schindler visited for a few months in 1940 and moved to Kraków to live with Oskar in 1941.[36][37]
