Blitzkrieg was based on speed, co-ordination and movement; the major science of this approach was the ability to get large mobile forces through weak points in the enemies defences and then cause damage when behind his static lines. With large formations cut off from communication and logistics, pressure could then be put on interior defences. Its aim was to create panic amongst the civilian population. A civil population on the move can be absolute havoc for a defending army trying to get its forces to the war front. With so much focus placed on the frontline, if this could be penetrated then the ensuing doubt, confusion and rumour were sure to paralyse both the government and the defending military.

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]
On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households.[12] The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship.[13] By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.[14][15]
Soon afterwards, the gas chambers and crematoria were destroyed on Himmler's orders, since the regime wanted to hide the traces of its murdering machine ahead of the advancing Red Army. As Soviet troops came near to the camp in January 1945, it was hurriedly evacuated and 58 000 prisoners were driven out on a death march, during which most were killed. On the 27th of January 1945, the Red Army entered the camp (link in Czech). They found 7 650 exhausted and starving prisoners and a number of pieces of evidence of crimes that the Nazis had not had time to destroy. In the camp stores they found almost eight tonnes of human hair and over a million men's suits and women's dresses.
By the spring of 1942, the Nazis had established six killing centers (death camps) in Poland: Chelmno (Kulmhof), Belzec, Sobibor, Treblinka, Maidanek and Auschwitz. All were located near railway lines so that Jews could be easily transported daily. A vast system of camps (called Lagersystem) supported the death camps. The purpose of these camps varied: some were slave labor camps, some transit camps, others concentration camps and their sub­camps, and still others the notorious death camps. Some camps combined all of these functions or a few of them. All the camps were intolerably brutal.
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.
His middle-class Catholic family belonged to the German-speaking community in the Sudetenland. The young Schindler, who attended German grammar school and studied engineering, was expected to follow in the footsteps of his father and  take charge of the family farm-machinery plant. Some of Schindler’s schoolmates and childhood neighbors were Jews, but with none of them did he develop an intimate or lasting friendship. Like most of the German-speaking youths of the Sudetenland, he subscribed to Konrad Henlein’s Sudeten German Party, which strongly supported the Nazi Germany and actively strove for the dismemberment of Czechoslovakia and their annexation to Germany . When the Sudetenland was incorporated into Nazi Germany in 1938, Schindler became a formal member of the Nazi party.

Our perception of land operations in the Second World War has...been distorted by an excessive emphasis upon the hardware employed. The main focus of attention has been the tank and the formations that employed it, most notably the (German) panzer divisions. Despite the fact that only 40 of the 520 German divisions that saw combat were panzer divisions (there were also an extra 24 motorised/panzergrenadier divisions), the history of German operations has consistently almost exclusively been written largely in terms of blitzkrieg and has concentrated almost exclusively upon the exploits of the mechanized formations. Even more misleadingly, this presentation of ground combat as a largely armored confrontation has been extended to cover Allied operations, so that in the popular imagination the exploits of the British and Commonwealth Armies, with only 11 armored divisions out of 73 (that saw combat), and of the Americans in Europe, with only 16 out of 59, are typified by tanks sweeping around the Western Desert or trying to keep up with Patton in the race through Sicily and across northern France. Of course, these armored forces did play a somewhat more important role in operations than the simple proportions might indicate, but it still has to be stressed that they in no way dominated the battlefield or precipitated the evolution of completely new modes of warfare.
Schwerpunktprinzip was a heuristic device (conceptual tool or thinking formula) used in the German army since the nineteenth century, to make decisions from tactics to strategy about priority. Schwerpunkt has been translated as centre of gravity, crucial, focal point and point of main effort. None of these forms is sufficient to describe the universal importance of the term and the concept of Schwerpunktprinzip. Every unit in the army, from the company to the supreme command, decided on a Schwerpunkt through schwerpunktbildung, as did the support services, which meant that commanders always knew what was most important and why. The German army was trained to support the Schwerpunkt, even when risks had to be taken elsewhere to support the point of main effort.[61] Through Schwerpunktbildung, the German army could achieve superiority at the Schwerpunkt, whether attacking or defending, to turn local success at the Schwerpunkt into the progressive disorganisation of the opposing force, creating more opportunities to exploit this advantage, even if numerically and strategically inferior in general. In the 1930s, Guderian summarised this as "Klotzen, nicht kleckern!" ("Kick, don't spatter them!").[62][63]
The Holocaust was a 20th Century atrocity caused by men and women who were driven by hatred, ignorance and greed, Auschwitz is a reminder of what can happen if we let for one moment the fanatics/extremists and some elected politicians tell us that our way of life is threatened, we have a duty to our children and theirs to show them what really happens when hatred and discrimination is used as a weapon against your fellow man, It is a crime in itself to even deny the holocaust, there are no words to describe the pity I feel for those who lack any emotion or lack the intelligent to absorb the truth,

In the view of Christian Gerlach, Hitler announced his decision to annihilate the Jews on or around 12 December 1941, probably on 12 December during a speech to the Gauleiters, part of the Nazi Party leadership.[259] This was one day after the German declaration of war against the United States, which followed the Japanese attack on Pearl Harbour on 7 December and the United States declaration of war on Japan on 8 December.[260] According to Deborah Dwork and Robert Jan van Pelt, Hitler had trusted American Jews, whom he assumed were all-powerful, to keep their government out of the war in the interests of German Jews. When America declared war, the Jews were blamed.[261] Joseph Goebbels, the Reich Minister of Propaganda, noted of Hitler's speech: "He warned the Jews that if they were to cause another world war, it would lead to their destruction. ... Now the world war has come. The destruction of the Jews must be its necessary consequence."[260][o]
As in the concentration camps, those prisoners selected for work faced appalling conditions and severe treatment. After being woken at dawn, they would have to stand in line for the roll call and endure many hours of hard labour. At the end of the working day, exhausted, they returned to the camp, when they would once again have to stand in line for evening roll call.

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.

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]

The possible final remnant will, since it will undoubtedly consist of the most resistant portion, have to be treated accordingly because it is the product of natural selection and would, if released, act as the seed of a new Jewish revival (see the experience of history.) In the course of the practical execution of the final solution, Europe will be combed through from west to east. Germany proper, including the Protectorate of Bohemia and Moravia, will have to be handled first due to the housing problem and additional social and political necessities. The evacuated Jews will first be sent, group by group, to so-called transit ghettos, from which they will be transported to the East.[256]
General Erwin Rommel, who would later gain fame in the African desert as the "Desert Fox", led the 7th Panzer Division as it crashed through the Belgian defenses into France, skirting the Maginot Line and then smashing it from behind. This was a new kind of warfare integrating tanks, air power, artillery, and motorized infantry into a steel juggernaut emphasizing speedy movement and maximization of battlefield opportunities. Rommel kept a journal of his experiences. In this excerpt, he describes the action on May 14 as he leads a tank attack against French forces near the Muese River on the Belgian border:
Several resistance groups were formed, such as the Jewish Combat Organization in the Warsaw Ghetto and the United Partisan Organization in Vilna.[310] Over 100 revolts and uprisings occurred in at least 19 ghettos and elsewhere in Eastern Europe. The best known is the Warsaw Ghetto Uprising of 1943, when around 1,000 poorly armed Jewish fighters held the SS at bay for four weeks.[311][q] During a revolt in Treblinka on 2 August 1943, inmates killed five or six guards and set fire to camp buildings; several managed to escape.[316][317] In the Białystok Ghetto on 16 August 1943, Jewish insurgents fought for five days when the Germans announced mass deportations.[318] On 14 October 1943, Jewish prisoners in Sobibór, including Jewish-Soviet prisoners of war, attempted an escape,[319] killing 11 SS officers and a couple of Ukrainian camp guards.[320] Around 300 escaped, but 100 were recaptured and shot.[321] On 7 October 1944, 300 Jewish members of the Sonderkommando at Auschwitz, who learned they were about to be killed, attacked their guards and blew up crematorium IV. Three SS officers were killed, one of whom was stuffed into an oven, as was a German kapo. None of the Sonderkommando rebels survived the uprising.[322]
Once a strategic target had been selected, Stuka dive bombers were sent in to ‘soften’ up the enemy, destroy all rail lines, communication centres and major rail links. This was done as the German tanks were approaching and the planes withdrew only at the last minute so that the enemy did not have time to recover their senses when the tanks attacked supported by infantry. 
When the Nazi’s rose to power they built facilities to hold and, eventually kill, their enemies. When the first concentration camps were built in 1933, this primarily meant political dissidents and opponents of the Nazi government, such as German Communists, Socialists, Social Democrats but would grow to include asocial groups – Gypsies, Jehovah’s Witnesses, the homeless, the mentally ill and homosexuals.  It was not until Kristallnacht that the prisoners became primarily Jewish.
November 4, 1943 - Quote from Nazi newspaper, Der Stürmer, published by Julius Streicher - "It is actually true that the Jews have, so to speak, disappeared from Europe and that the Jewish 'Reservoir of the East' from which the Jewish pestilence has for centuries beset the peoples of Europe has ceased to exist. But the Führer of the German people at the beginning of the war prophesied what has now come to pass."

Various other German industrial enterprises, such as Krupp and Siemens-Schuckert, built factories with their own subcamps.[68] There were around 40[69] or 50[70] such camps, 28 of them near industrial plants, each camp holding hundreds or thousands of prisoners.[71] Designated as Aussenlager (external camp), Nebenlager (extension or subcamp), or Arbeitslager (labor camp),[69] camps were built at Blechhammer, Jawiszowice, Jaworzno, Lagisze, Mysłowice, Trzebinia, and centers as far afield as the Protectorate of Bohemia and Moravia in Czechoslovakia.[72][73][74] Industries with satellite camps included coal mines, foundries and other metal works, and chemical plants. Prisoners were also made to work in forestry and farming.[75] Budy, for example, was a farming subcamp where prisoners worked 12-hour days, often in the fields, but sometimes tending animals, cleaning ponds, digging ditches, and making compost. Human ashes from the crematorium were mixed with sod and manure to make the compost.[76] Incidents of sabotage to decrease production took place in several subcamps, including Charlottengrube, Gleiwitz II, and Rajsko.[77]
Soon after he became chancellor, Hitler called for new elections in an effort to get full control of the Reichstag, the German parliament, for the Nazis. The Nazis used the government apparatus to terrorize the other parties. They arrested their leaders and banned their political meetings. Then, in the midst of the election campaign, on February 27, 1933, the Reichstag building burned. A Dutchman named Marinus van der Lubbe was arrested for the crime, and he swore he had acted alone. Although many suspected the Nazis were ultimately responsible for the act, the Nazis managed to blame the Communists, thus turning more votes their way.
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.
The economic strains of the Great Depression led some in the German medical establishment to advocate murder (euphemistically called "euthanasia") of the "incurable" mentally and physically disabled as a cost-saving measure to free up funds for the curable.[66] By the time the National Socialist German Workers' Party, or Nazi Party,[j] came to power in 1933, there was already a tendency to seek to save the racially "valuable", while ridding society of the racially "undesirable".[68] The party had originated in 1920[67] as an offshoot of the völkisch movement, and it adopted that movement's antisemitism.[69] Early antisemites in the party included Dietrich Eckart, publisher of the Völkischer Beobachter, the party's newspaper, and Alfred Rosenberg, who wrote antisemitic articles for it in the 1920s. Rosenberg's vision of a secretive Jewish conspiracy ruling the world would influence Hitler's views of Jews by making them the driving force behind communism.[70] The origin and first expression of Hitler's antisemitism remain a matter of debate.[71] Central to his world view was the idea of expansion and lebensraum (living space) for Germany. Open about his hatred of Jews, he subscribed to the common antisemitic stereotypes.[72] From the early 1920s onwards, he compared the Jews to germs and said they should be dealt with in the same way. He viewed Marxism as a Jewish doctrine, said he was fighting against "Jewish Marxism", and believed that Jews had created communism as part of a conspiracy to destroy Germany.[73]
In 1993, Steven Spielberg’s Schindler’s List brought to the screen a story that had gone untold since the tragic events of the Holocaust. Oskar Schindler, a Nazi party member, used his pull within the party to save the lives of more than 1000 Jewish individuals by recruiting them to work in his Polish factory. Here are some facts about Spielberg’s groundbreaking film on its 25th anniversary.
