Uniquely at Auschwitz, prisoners were tattooed with a serial number, on their left breast for Soviet prisoners of war[97] and on the left arm for civilians.[98] Categories of prisoner were distinguishable by triangular pieces of cloth (German: Winkel) sewn onto on their jackets below their prisoner number. Political prisoners (Schutzhäftlinge or Sch), mostly Poles, had a red triangle, while criminals (Berufsverbrecher or BV) were mostly German and wore green. Asocial prisoners (Asoziale or Aso), which included vagrants, prostitutes and the Roma, wore black. Purple was for Jehovah's Witnesses (Internationale Bibelforscher-Vereinigung or IBV)'s and pink for gay men, who were mostly German.[99] An estimated 5,000–15,000 gay men prosecuted under German Penal Code Section 175 (proscribing sexual acts between men) were detained in concentration camps, of which an unknown number were sent to Auschwitz.[100] Jews wore a yellow badge, the shape of the Star of David, overlaid by a second triangle if they also belonged to a second category. The nationality of the inmate was indicated by a letter stitched onto the cloth. A racial hierarchy existed, with German prisoners at the top. Next were non-Jewish prisoners from other countries. Jewish prisoners were at the bottom.[101]
The Nazis regarded the Slavs as subhuman, or Untermenschen.[426] In a secret memorandum dated 25 May 1940, Himmler stated that it was in German interests to foster divisions between the ethnic groups in the East. He wanted to restrict non-Germans in the conquered territories to schools that would only teach them how to write their own name, count up to 500, and obey Germans.[427][y] In November 1939 German planners called for "the complete destruction" of all Poles[430] and resettlement of the land by German colonists.[431] The Polish political leadership was the target of a campaign of murder (Intelligenzaktion and AB-Aktion).[432] Between 1.8 and 1.9 million non-Jewish Polish citizens perished at German hands during the course of the war; about four-fifths were ethnic Poles and the rest Ukrainians and Belarusians.[410] At least 200,000 died in concentration camps, around 146,000 in Auschwitz. Others died in massacres or in uprisings such as the Warsaw Uprising, where 120,000–200,000 were killed.[433] During the occupation, the Germans adopted a policy of restricting food and medical services, as well as degrading sanitation and public hygiene.[434] The death rate rose from 13 per 1000 before the war to 18 per 1000 during the war.[435] Around 6 million of World War II victims were Polish citizens; half the death toll were Jews.[436] Over the course of the war Poland lost 20 percent of its pre-war population.[436] Over 90 percent of the death toll came through non-military losses, through various deliberate actions by Germany and the Soviet Union.[433] Polish children were also kidnapped by Germans to be "Germanized", with perhaps as many as 200,000 children stolen from their families.[437]
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.

Blitzkrieg also has had some influence on subsequent militaries and doctrines. The Israel Defense Forces may have been influenced by blitzkrieg in creating a military of flexible armored spearheads and close air support. The 1990's United States theorists of " Shock and awe" claim blitzkrieg as a subset of strategies which they term "rapid dominance".

Most Holocaust historians define the Holocaust as the enactment, between 1941 and 1945, of the German state policy to exterminate the European Jews.[a] In Teaching the Holocaust (2015), Michael Gray, a specialist in Holocaust education,[27] offers three definitions: (a) "the persecution and murder of Jews by the Nazis and their collaborators between 1933 and 1945", which views the events of Kristallnacht in Germany in 1938 as an early phase of the Holocaust; (b) "the systematic mass murder of the Jews by the Nazi regime and its collaborators between 1941 and 1945", which acknowledges the shift in German policy in 1941 toward the extermination of the Jewish people in Europe; and (c) "the persecution and murder of various groups by the Nazi regime and its collaborators between 1933 and 1945", which includes all the Nazis' victims. The third definition fails, Gray writes, to acknowledge that only the Jewish people were singled out for annihilation.[28]

Criterion (vi): Auschwitz Birkenau, monument to the deliberate genocide of the Jews by the German Nazi regime and to the deaths of countless others, bears irrefutable evidence to one of the greatest crimes ever perpetrated against humanity. It is also a monument to the strength of the human spirit which in appalling conditions of adversity resisted the efforts of the German Nazi regime to suppress freedom and free thought and to wipe out whole races. The site is a key place of memory for the whole of humankind for the Holocaust, racist policies and barbarism; it is a place of our collective memory of this dark chapter in the history of humanity, of transmission to younger generations and a sign of warning of the many threats and tragic consequences of extreme ideologies and denial of human dignity.
Around Birkenau are several nature conservation areas and a considerable number of hiking paths. These are found on the one hand in the woods around Birkenau, but on the other hand, the Höhenweg (“Height Way”, European walking route E1, plateau path between Birkenau and Reisen), for example, is also worth visiting, as there is a striking view over Birkenau and Nieder-Liebersbach.
To achieve a breakout, armored forces themselves would attack the enemy's defensive line directly, supported by their own infantry (Panzergrenadiers), artillery fire and aerial bombardment in order to create a breach in the enemy's line. Through this breach the tanks could break through without the traditional encumbrance of the slow logistics of a pure infantry regiment. The breaching force never lost time by 'stabilising its flanks' or by regrouping; rather it continued the assault in a towards the interior of the enemies lines, sometimes diagonally across them. This point of breakout has been labeled a "hinge", but only because a change in direction of the defender's lines is naturally weak and therefore a natural target for blitzkrieg assault.

Dan Stone, a specialist in the historiography of the Holocaust, lists ethnic Poles, Ukrainians, Soviet prisoners of war, Jehovah's Witnesses, black Germans, and homosexuals as among the groups persecuted by the Nazis; he writes that the occupation of eastern Europe can also be viewed as genocidal. But the German attitude toward the Jews was different in kind, he argues. The Nazis regarded the Jews not as racially inferior, deviant, or enemy nationals, as they did other groups, but as a "Gegenrasse: a 'counter-race', that is to say, not really human at all". The Holocaust, for Stone, is therefore defined as the genocide of the Jews, although he argues that it cannot be "properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans".[d] Donald Niewyk and Francis Nicosia, in The Columbia Guide to the Holocaust (2000), favour a definition that focuses on the Jews, Roma, and Aktion T4 victims: "The Holocaust—that is, Nazi genocide—was the systematic, state-sponsored murder of entire groups determined by heredity. This applied to Jews, Gypsies, and the handicapped."[33]
After the start of World War II, Adolf Hitler (1889-1945), the chancellor of Germany from 1933 to 1945, implemented a policy that came to be known as the “Final Solution.” Hitler was determined not just to isolate Jews in Germany and countries annexed by the Nazis, subjecting them to dehumanizing regulations and random acts of violence. Instead, he became convinced that his “Jewish problem” would be solved only with the elimination of every Jew in his domain, along with artists, educators, Gypsies, communists, homosexuals, the mentally and physically handicapped and others deemed unfit for survival in Nazi Germany.
In 1995, David Glantz stated that for the first time, blitzkrieg was defeated in summer and the opposing Soviet forces were able to mount a successful counter-offensive.[98] The Battle of Kursk ended with two Soviet counter-offensives and the revival of deep operations.[98] In the summer of 1944, the Red Army destroyed Army Group Centre in Operation Bagration, using combined-arms tactics for armour, infantry and air power in a coordinated strategic assault, known as deep operations, which led to an advance of 600 kilometres (370 mi) in six weeks.[106]
The core principle behind Blitzkrieg was to concentrate the force on a single point. The German called this penetration or breakthrough, and its purpose was to rupture enemy defenses. The main objective: apply overwhelming force at a weak point in the enemy line to force an opening. This opening functions as the first stage of tactical deep battle in its Blitzkrieg form, and it was so effective that the Germans often referred to it as “the beginning of the end”.
At this time only the main camp, later known as Auschwitz I, had been established. Himmler ordered the construction of a second camp for 100,000 inmates on the site of the village of Brzezinka, roughly two miles from the main camp. This second camp, now known as Birkenau or Auschwitz II, was initially intended to be filled with captured Russian POWs who would provide the slave labor to build the SS “utopia” in Upper Silesia. Chemical giant I G Farben expressed an interest in utilizing this labor force, and extensive construction work began in October 1941 under terrible conditions and with massive loss of life. About 10,000 Russian POWs died in this process. The greater part of the apparatus of mass extermination was eventually built in the Birkenau camp and the majority of the victims were murdered here.
There was initially little to distinguish Schindler from the other businessmen who cooperated with the Nazis, until the liquidation of the Kraków ghetto threatened the workers he relied on. As the war dragged on and Schindler began to build personal relationships with his workers, he underwent a personal transformation. Over time, Schindler became less concerned with making a profit; soon he was spending enormous sums of money to keep his workers safe.
Frieser wrote that the Heer (German pronunciation: [ˈheːɐ̯])[k] was not ready for blitzkrieg at the start of the war. A blitzkrieg method called for a young, highly skilled mechanised army. In 1939–40, 45 percent of the army was 40 years old and 50 percent of the soldiers had only a few weeks' training. The German army, contrary to the blitzkrieg legend, was not fully motorised and had only 120,000 vehicles, compared to the 300,000 of the French Army. The British also had an "enviable" contingent of motorised forces. Thus, "the image of the German 'Blitzkrieg' army is a figment of propaganda imagination". During the First World War the German army used 1.4 million horses for transport and in the Second World War used 2.7 million horses; only ten percent of the army was motorised in 1940.[130]
Although the term "concentration camps" is often used to describe all Nazi camps, there were actually a number of different kinds of camps, including transit camps, forced-labor camps, and death camps. In some of these camps there was at least a small chance to survive; while in others, there was no chance at all. When and where were these camps built? How many people were murdered in each one?

On 19 November 1942, the Red Army launched Operation Uranus, a two-pronged attack targeting the weaker Romanian and Hungarian armies protecting the German 6th Army's flanks. The Axis forces on the flanks were overrun and the 6th Army was cut off and surrounded in the Stalingrad area. Adolf Hitler ordered that the army stay in Stalingrad and make no attempt to break out; instead, attempts were made to supply the army by air and to break the encirclement from the outside. Heavy fighting continued for another two months. By the beginning of February 1943, the Axis forces in Stalingrad had exhausted their ammunition and food. The remaining units of the 6th Army surrendered. The battle lasted five months, one week and three days. Show less
In the Lviv pogroms in occupied Poland in July 1941, some 6,000 Polish Jews were murdered in the streets, on top of 3,000 arrests and mass shootings by Einsatzgruppe C.[231][m] During the Jedwabne pogrom, on 10 July 1941, a group of 40 Polish men killed several hundred Jews; around 300 were burned alive in a barn. The attack is thought to have been organized by the German Security Police (Sicherheitsdienst).[233] A long debate about who was responsible for the Jedwabne murders was triggered in 2001 by the publication of Jan T. Gross's book Neighbors: The Destruction of the Jewish Community in Jedwabne, Poland.[234] The response to the book was described as "the most prolonged and far-reaching of any discussion of the Jewish issue in Poland since the Second World War".[235]
While the labour camps at Auschwitz and Majdanek used inmates for slave labour to support the German war effort, the extermination camps at Belzec, Treblinka, and Sobibor had one task alone: killing. At Treblinka a staff of 120, of whom only 30 were SS (the Nazi paramilitary corps), killed some 750,000 to 925,000 Jews during the camp’s 17 months of operation. At Belzec German records detail a staff of 104, including about 20 SS, who killed some 500,000 Jews in less than 10 months. At Sobibor they murdered between 200,000 and 250,000. These camps began operation during the spring and summer of 1942, when the ghettos of German-occupied Poland were filled with Jews. Once they had completed their missions—murder by gassing, or “resettlement in the east,” to use the language of the Wannsee protocols—the Nazis closed the camps. There were six extermination camps, all in German-occupied Poland, among the thousands of concentration and slave-labour camps throughout German-occupied Europe.
Treatment inside the concentration camps were horrible. Prisoners were given tiny rations of food and forced into physical labor. They often slept more than three to a bed without pillows or blankets, even in the winter months. In many concentration camps, Nazi doctors conducted medical experiments on prisoners against their will, in many cases killing the prisoners in the process.

The Nuremberg trials were a series of military tribunals, held by the Allied forces after World War II in Nuremberg, Germany, to prosecute prominent members of the political, military, and economic leadership of Nazi Germany. The first of these trials was the 1945–1946 trial of the major war criminals before the International Military Tribunal (IMT).[456] This tribunal tried 22 political and military leaders of the Third Reich,[457] except for Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, all of whom had committed suicide several months before.[456]
On January 20, 1942, Reinhard Heydrich convened the Wannsee Conference at a lakeside villa in Berlin to organize the “final solution to the Jewish question.” Around the table were 15 men representing government agencies necessary to implement so bold and sweeping a policy. The language of the meeting was clear, but the meeting notes were circumspect:
"...(t)hroughout ( the Polish Campaign), the employment of the mechanized units revealed the idea that they were intended solely to ease the advance and to support the activities of the infantry....Thus, any strategic exploitation of the armored idea was still-born. The paralysis of command and the breakdown of morale were not made the ultimate aim of the ... German ground and air forces, and were only incidental by-products of the traditional maneuvers of rapid encirclement and of the supporting activities of the flying artillery of the Luftwaffe, both of which had has their purpose the physical destruction of the enemy troops. Such was the Vernichtungsgedanke of the Polish campaign."
Sometimes the mere presence of German troops in the vicinity was sufficient to spur a massacre. One example is what happened in the Polish village of Jedwabne, where neighbours murdered their Jewish neighbours. For years the massacre was blamed on the Germans, though many Poles likely knew that the local population had turned against its own Jews. In the Baltics, where the Germans were greeted as liberators by some segments of the population, the lure of political independence and the desire to erase any collaboration with the previous Soviet occupiers led nationalist bands to murder local Jews.
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.
While blitzkrieg was a tactic focused on speed, it would be wrong for any bedroom strategist (like myself) to focus on that characteristic alone and to conclude that speed is all that matters. It is definitely important, but it is important to look deeper at this tactic in order to understand why speed was important in the first place, the core principles behind the strike and how you can employ equivalent tactics in the business world.
His tasks for the Abwehr included collecting information on railways, military installations, and troop movements, as well as recruiting other spies within Czechoslovakia, in advance of a planned invasion of the country by Nazi Germany.[9] He was arrested by the Czech government for espionage on 18 July 1938 and immediately imprisoned, but was released as a political prisoner under the terms of the Munich Agreement, the instrument under which the Czech Sudetenland was annexed into Germany on 1 October.[10][11] Schindler applied for membership in the Nazi Party on 1 November and was accepted the following year.[12]
