During the Battle of France in 1940, De Gaulle's 4th Armour Division and elements of the British 1st Army Tank Brigade in the British Expeditionary Force both made probing attacks on the German flank, actually pushing into the rear of the advancing armored columns at times (See Battle of Arras (1940) ). This may have been a reason for Hitler to call a halt to the German advance. Those attacks combined with Maxime Weygand's Hedgehog tactic would become the major basis for responding to blitzkrieg attacks in the future: deployment in depth, permitting enemy forces to bypass defensive concentrations, reliance on anti-tank guns, strong force employment on the flanks of the enemy attack, followed by counter-attacks at the base to destroy the enemy advance in detail. Holding the flanks or 'shoulders' of a penetration was essential to channeling the enemy attack, and artillery, properly employed at the shoulders, could take a heavy toll of attackers. While Allied forces in 1940 lacked the experience to successfully develop these strategies, resulting in France's capitulation with heavy losses, they characterized later Allied operations. For example, at the Battle of Kursk the Red Army employed a combination of defense in great depth, extensive minefields, and tenacious defense of breakthrough shoulders. In this way they depleted German combat power even as German forces advanced. In August 1944 at Mortain, stout defense and counterattacks by the US and Canadian armies closed the Falaise Gap. In the Ardennes, a combination of hedgehog defense at Bastogne, St Vith and other locations, and a counterattack by the US 3rd Army were employed.
At Auschwitz alone, more than 2 million people were murdered in a process resembling a large-scale industrial operation. A large population of Jewish and non-Jewish inmates worked in the labor camp there; though only Jews were gassed, thousands of others died of starvation or disease. During the summer of 1944, even as the events of D-Day (June 6, 1944) and a Soviet offensive the same month spelled the beginning of the end for Germany in the war, a large proportion of Hungary’s Jewish population was deported to Auschwitz, and as many as 12,000 Jews were killed every day.
At the end of the war, between 50,000 and 100,000 Jewish survivors were living in three zones of occupation: American, British and Soviet. Within a year, that figure grew to about 200,000. The American zone of occupation contained more than 90 percent of the Jewish displaced persons (DPs). The Jewish DPs would not and could not return to their homes, which brought back such horrible memories and still held the threat of danger from anti-Semitic neighbors. Thus, they languished in DP camps until emigration could be arranged to Palestine, and later Israel, the United States, South America and other countries. The last DP camp closed in 1957 (David S. Wyman, "The United States," in David S. Wyman, ed., The World Reacts to the Holocaust, Baltimore, MD: Johns Hopkins University Press, 1996, pp. 707­10).
Other former staff were hanged for war crimes in the Dachau Trials and the Belsen Trial, including camp leaders Josef Kramer, Franz Hössler, and Vinzenz Schöttl; doctor Friedrich Entress; and guards Irma Grese and Elisabeth Volkenrath.[268] The Frankfurt Auschwitz trials, held in West Germany from 20 December 1963 to 20 August 1965, convicted 17 of 22 defendants, giving them prison sentences ranging from life to three years and three months.[269] Bruno Tesch and Karl Weinbacher, the owner and the chief executive officer of the firm Tesch & Stabenow, one of the suppliers of Zyklon B, were executed for knowingly supplying the chemical for use on humans.[270]
The first gassings at Auschwitz took place in early September 1941, when around 850 inmates—Soviet prisoners of war and sick Polish inmates—were killed with Zyklon B in the basement of block 11 in Auschwitz I. The building proved unsuitable, so gassings were conducted instead in crematorium I, also in at Auschwitz I, which operated until December 1942. There, more than 700 victims could be killed at once.[157] Tens of thousands were killed in crematorium I.[158] To keep the victims calm, they were told they were to undergo disinfection and de-lousing; they were ordered to undress outside, then were locked in the building and gassed. After its decommissioning as a gas chamber, the building was converted to a storage facility and later served as an SS air raid shelter.[159] The gas chamber and crematorium were reconstructed after the war. Dwork and van Pelt write that a chimney was recreated; four openings in the roof were installed to show where the Zyklon B had entered; and two of the three furnaces were rebuilt with the original components.[160]
^ Now came the riposte - a counter-attack [...] from the forest of Villers-Cotterets [...]. The French had developed a light and fast-moving tank. Two generals, Debeney on the British right, and Mangin, to his right, began the tactics that were to become famous in 1940 as Blitzkrieg - tanks, fast-moving infantry, and aircraft flying low to keep the German gunners' heads down. Three hundred tanks (Renault) and eighteen divisions, two of them American, struck in open cornfield, entirely by surprise, and went five miles forward. With the whole of the German force in the Marne salient threatened by a cut-off, Ludendorff pulled back from it, back to Chemin des Dames. By 4 August the French had taken 30,000 prisoners and 600 guns.[46]

The town of Auschwitz was a major railroad hub, with many train tracks coming into it, and a large marshaling yard near the Auschwitz station. Standing on the railroad overpass in 1941, Himmler realized that Birkenau was an ideal location for transporting people by rail from all over Europe, although the plans for exterminating the Jews were not finalized until the Nazis were confident that they would win their war against the Soviet Union.

In 1933, Jews in Germany numbered around 525,000, or only 1 percent of the total German population. During the next six years, Nazis undertook an “Aryanization” of Germany, dismissing non-Aryans from civil service, liquidating Jewish-owned businesses and stripping Jewish lawyers and doctors of their clients. Under the Nuremberg Laws of 1935, anyone with three or four Jewish grandparents was considered a Jew, while those with two Jewish grandparents were designated Mischlinge (half-breeds).
^ 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.
In the 1930s, Hitler had ordered rearmament programs that cannot be considered limited. In November 1937 Hitler had indicated that most of the armament projects would be completed by 1943–45.[129] The rearmament of the Kriegsmarine was to have been completed in 1949 and the Luftwaffe rearmament program was to have matured in 1942, with a force capable of strategic bombing with heavy bombers. The construction and training of motorised forces and a full mobilisation of the rail networks would not begin until 1943 and 1944 respectively.[130] Hitler needed to avoid war until these projects were complete but his misjudgements in 1939 forced Germany into war before rearmament was complete.[131]
The orders for the final evacuation and liquidation of the camp were issued in mid-January 1945. The Germans left behind in the main Auschwitz camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long; the rest, approximately 58,000 people, were evacuated by foot into the depths of the Third Reich.

Many people ask, "Why didn't the Jews fight back?" Well, they did. With limited weapons and at a severe disadvantage, they found creative ways to subvert the Nazi system. They worked with partisans in the forests, fought to the last man in the Warsaw Ghetto, revolted at the Sobibor death camp, and blew up gas chambers at Auschwitz. Learn more about the resistance, both by Jews and non-Jews, to the Nazis.
Auschwitz Birkenau was the principal and most notorious of the six concentration and extermination camps established by Nazi Germany to implement its Final Solution policy which had as its aim the mass murder of the Jewish people in Europe. Built in Poland under Nazi German occupation initially as a concentration camp for Poles and later for Soviet prisoners of war, it soon became a prison for a number of other nationalities. Between the years 1942-1944 it became the main mass extermination camp where Jews were tortured and killed for their so-called racial origins. In addition to the mass murder of well over a million Jewish men, women and children, and tens of thousands of Polish victims, Auschwitz also served as a camp for the racial murder of thousands of Roma and Sinti and prisoners of several European nationalities.
The generally accepted definition of blitzkrieg operations include the use of maneuver rather than attrition to defeat an opponent, and describe operations using combined arms concentration of mobile assets at a focal point, armour closely supported by mobile infantry, artillery and close air support assets. These tactics required the development of specialized support vehicles, new methods of communication, new tactics, and an effective decentralized command structure. Broadly speaking, blitzkrieg operations required the development of mechanized infantry, self-propelled artillery and engineering assets that could maintain the rate of advance of the tanks. German forces avoided direct combat in favour of interrupting an enemy's communications, decision-making, logistics and of reducing morale. In combat, blitzkrieg left little choice for the slower defending forces but to clump into defensive pockets that were encircled and then destroyed by following German infantry.
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.
took unlimited advantage of their power.  They could beat us, torture us, even kill us without having to answer to anyone. Those who could not take this treatment threw themselves into the electric fence.  These suicides built up the rage of our tormentors even more.  One day, when the number of musicians who had killed themselves the night before was higher than usual, they called us all together and said 'sons of whores, I warn you all, if you keep leaping into the electric wire, I will kill you all like dogs'.
Close air support was provided in the form of the dive bomber and medium bomber. They would support the focal point of attack from the air. German successes are closely related to the extent to which the German Luftwaffe was able to control the air war in early campaigns in Western and Central Europe, and the Soviet Union. However, the Luftwaffe was a broadly based force with no constricting central doctrine, other than its resources should be used generally to support national strategy. It was flexible and it was able to carry out both operational-tactical, and strategic bombing. Flexibility was the Luftwaffe's strength in 1939–1941. Paradoxically, from that period onward it became its weakness. While Allied Air Forces were tied to the support of the Army, the Luftwaffe deployed its resources in a more general, operational way. It switched from air superiority missions, to medium-range interdiction, to strategic strikes, to close support duties depending on the need of the ground forces. In fact, far from it being a specialist panzer spearhead arm, less than 15 percent of the Luftwaffe was intended for close support of the army in 1939.[67]
The superior race was the "Aryans," the Germans. The word Aryan, "derived from the study of linguistics, which started in the eighteenth century and at some point determined that the Indo-Germanic (also known as Aryan) languages were superior in their structures, variety, and vocabulary to the Semitic languages that had evolved in the Near East. This judgment led to a certain conjecture about the character of the peoples who spoke these languages; the conclusion was that the 'Aryan' peoples were likewise superior to the 'Semitic' ones" (Leni Yahil, The Holocaust: The Fate of European Jewry, New York: Oxford University Press, 1990, p. 36).

^ Nothing appeared in Luftwaffe 'doctrine' stipulating "terror" as a major operational factor. The method of "terror", was denied to German aerial operations (and strategic bombing methods) by the Luftwaffe field manual The Conduct of Air Operations, Regulation 16, issued in 1935 (Corum 1992, pp. 167–169). Regulation 16 denied "terror" operations against civilians, and it was not until 1942 when indiscriminate "terror" operations, in which terror and civilian casualties become the primary target, took place (Corum 1997, pp. 7, 143).
When Germany invaded Poland in September 1939, triggering World War II, Adolf Hitler ordered that the Polish leadership and intelligentsia be destroyed.[16] Approximately 65,000 civilians, viewed as inferior to the Aryan master race, had been killed by the end of 1939. In addition to leaders of Polish society, the Nazis killed Jews, prostitutes, the Roma, and the mentally ill.[17][18] SS-Obergruppenführer Reinhard Heydrich, then head of the Gestapo, ordered on 21 September 1939 that Polish Jews be rounded up and concentrated into cities with good rail links. Initially the intention was to deport them to points further east, or possibly to Madagascar.[19] Two years later, in June 1941, in an attempt to obtain new territory, Hitler invaded the Soviet Union.[8]
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.

By the war’s end, approximately 1.25 million people had been killed here, more than 90 per cent of them Jewish.  Birkenau was also where the infamous Dr Josef Mengele performed many of his experiments on pregnant women, dwarves, and twins.  As was the case in the other camps of Auschwitz, there was a mass evacuation immediately before the Soviets reached the camp.  Only a few thousand prisoners remained to be liberated when the Soviets arrived on 27 January 1945.
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.
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.

After the Nuremberg war crimes trials finished, the United States spearheaded the effort to end genocide and become a champion for the prevention of crimes against humanity. The U.S. pushed for greater international effort, helping to draft the 1948 Genocide Convention. President Harry Truman addressed Congress urging the Convention’s passage. He stressed the role the United States had to play in “outlawing the world-shocking crime of genocide.”
The Germans isolated all the camps and sub-camps from the outside world and surrounded them with barbed wire fencing. All contact with the outside world was forbidden. However, the area administered by the commandant and patrolled by the SS camp garrison went beyond the grounds enclosed by barbed wire. It included an additional area of approximately 40 square kilometers (the so-called “Interessengebiet” - the interest zone), which lay around the Auschwitz I and Auschwitz II-Birkenau camps.

Birkenau was the largest camp in the Auschwitz complex. It became primarily a centre for the mass murder of Jews brought there for extermination, and of Roma and Sinti prisoners during its final period. Sick prisoners and those selected for death from the whole Auschwitz complex – and, to a smaller extent, from other camps – were also gathered and systematically killed here. It ultimately became a place for the concentration of prisoners before they were transferred inside the Third Reich to work for German industry. Most of the victims of the Auschwitz complex, probably about 90%, were killed in the Birkenau camp.

Rather than repeating the World War One Schlieffen Plan, the Germans in 1940 advanced with their main thrust through the Ardennes Forest, in order to smash the vulnerable flank of the Allies. As 29 German divisions advanced through the Netherlands and Belgium in the north, 45 further divisions, including about 2,400 tanks in 7 divisions, burst through the Allied right flank and drove towards the English Channel.
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.
After Germany invaded Poland in September 1939, sparking World War II, the Germans converted Auschwitz I from an army barracks to hold Polish political prisoners.[3] The first prisoners, German criminals brought to the camp as functionaries, arrived in May 1940,[4] and the first gassing of prisoners took place in block 11 of Auschwitz I in September 1941. Auschwitz II–Birkenau went on to become a major site of the Nazis' Final Solution to the Jewish Question. From early 1942 until late 1944, transport trains delivered Jews from all over German-occupied Europe to the camp's gas chambers. Of the estimated 1.3 million people sent to Auschwitz, at least 1.1 million died,[5] around 90 percent of them Jews.[6] Approximately one in six Jews killed in the Holocaust died at the camp.[7] Others deported to Auschwitz included 150,000 non-Jewish Poles, 23,000 Roma, 15,000 Soviet prisoners of war, 400 Jehovah's Witnesses, tens of thousands of others of diverse nationalities, and an unknown number of gay men. Many of those not killed in the gas chambers died because of starvation, forced labor, infectious diseases, individual executions, and medical experiments.
Ya know i believe this sort of thing couldn't happen in the United States... Except the fact that everyone has a gun there are enough ppl to say, 'whoa this isn't right we need to stop this'. We just watched schindler's list last week in school and then discused it, we talked about how the nazis believed they could erase history, but there is always someone that will know what happened and we will always remember what happened, we will not forget and will not let it happen again.
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]
German operational theories were revised after the First World War. The Treaty of Versailles limited the Reichswehr to a maximum of 100,000 men, making impossible the deployment of mass armies. The German General Staff was abolished by the treaty but continued covertly as the Truppenamt (Troop Office), disguised as an administrative body. Committees of veteran staff officers were formed within the Truppenamt to evaluate 57 issues of the war.[29] By the time of the Second World War, their reports had led to doctrinal and training publications, including H. Dv. 487, Führung und Gefecht der verbundenen Waffen (Command and Battle of the Combined Arms), known as das Fug (1921–23) and Truppenführung (1933–34), containing standard procedures for combined-arms warfare. The Reichswehr was influenced by its analysis of pre-war German military thought, in particular infiltration tactics, which at the end of the war had seen some breakthroughs on the Western Front and the manoeuvre warfare which dominated the Eastern Front.
Some Germans, even some Nazis, dissented from the murder of the Jews and came to their aid. The most famous was Oskar Schindler, a Nazi businessman, who had set up operations using involuntary labour in German-occupied Poland in order to profit from the war. Eventually, he moved to protect his Jewish workers from deportation to extermination camps. In all occupied countries, there were individuals who came to the rescue of Jews, offering a place to hide, some food, or shelter for days or weeks or even for the duration of the war. Most of the rescuers did not see their actions as heroic but felt bound to the Jews by a common sense of humanity. Israel later recognized rescuers with honorary citizenship and commemoration at Yad Vashem, Israel’s memorial to the Holocaust.

The first experimental gassing took place in September 1941, when Lagerführer Karl Fritzsch, at the instruction of Rudolf Höss, killed a group of Soviet prisoners of war by throwing Zyklon B crystals into their basement cell in block 11 of Auschwitz I. A second group of 600 Soviet prisoners of war and around 250 sick Polish prisoners was gassed on 3–5 September.[29] The morgue was later converted to a gas chamber able to hold at least 700–800 people.[30] Zyklon B was dropped into the room through slits in the ceiling.[28] In the view of Filip Müller, one of the Sonderkommando who worked in crematorium I, tens of thousands of Jews were killed there from France, Holland, Slovakia, Upper Silesia, Yugoslavia, and from the Theresienstadt, Ciechanow, and Grodno ghettos.[31] The last inmates to be gassed in Auschwitz I, in December 1942, were 300–400 members of the Auschwitz II Sonderkommando, who had been forced to dig up that camp's mass graves, thought to hold 100,000 corpses, and burn the remains.[32]

An inmate's first encounter with the camp, if they were being registered and not sent straight to the gas chamber, would be at the prisoner reception centre, where they were tattooed, shaved, disinfected, and given their striped prison uniform. Built between 1942 and 1944, the center contained a bathhouse, laundry, and 19 gas chambers for delousing clothes. Debórah Dwork and Robert Jan van Pelt write that inmates would then leave this area via a porch that faced the gate with the Arbeit macht frei sign. The prisoner reception center of Auschwitz I became the visitor reception center of the Auschwitz-Birkenau Memorial and Museum.[20]
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 October 1944, after the SS transferred the Emalia Jews to Plaszow, Schindler sought and obtained authorization to relocate his plant to Brünnlitz (Brnenec) in Moravia, and reopen it exclusively as an armaments factory. One of his assistants drew several versions of a list of up to 1,200 Jewish prisoners needed to work in the new factory. These lists came to be known collectively as “Schindler's List.” Schindler met the specifications required by the SS to classify Brünnlitz as a subcamp of Gross-Rosen concentration camp and thereby facilitated the survival of around 800 Jewish men whom the SS deported from Plaszow via Gross-Rosen to Brünnlitz and between 300 and 400 Jewish women from Plaszow via Auschwitz.
