During the Holocaust, concentration camp prisoners received tattoos only at one location, Auschwitz. Incoming prisoners were assigned a camp serial number which was sewn to their prison uniforms. Only those prisoners selected for work were issued serial numbers; those prisoners sent directly to the gas chambers were not registered and received no tattoos.
Throughout the 1930s, the legal, economic, and social rights of Jews were steadily restricted.[83] On 1 April 1933, there was a boycott of Jewish businesses.[84] On 7 April 1933, the Law for the Restoration of the Professional Civil Service was passed, which excluded Jews and other "non-Aryans" from the civil service.[85] Jews were disbarred from practising law, being editors or proprietors of newspapers, joining the Journalists' Association, or owning farms.[86] In Silesia, in March 1933, a group of men entered the courthouse and beat up Jewish lawyers; Friedländer writes that, in Dresden, Jewish lawyers and judges were dragged out of courtrooms during trials.[87] Jewish students were restricted by quotas from attending schools and universities.[85] Jewish businesses were targeted for closure or "Aryanization", the forcible sale to Germans; of the approximately 50,000 Jewish-owned businesses in Germany in 1933, about 7,000 were still Jewish-owned in April 1939. Works by Jewish composers,[88] authors, and artists were excluded from publications, performances, and exhibitions.[89] Jewish doctors were dismissed or urged to resign. The Deutsches Ärzteblatt (a medical journal) reported on 6 April 1933: "Germans are to be treated by Germans only."[90]
The Soviets found 7,600 inmates in Auschwitz.[385] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division;[386] 13,000 corpses lay unburied, and another 10,000 people died from typhus or malnutrition over the following weeks.[387] The BBC's war correspondent, Richard Dimbleby, described the scenes that greeted him and the British Army at Belsen, in a report so graphic the BBC declined to broadcast it for four days, and did so, on 19 April, only after Dimbleby had threatened to resign.[388]

The gate house at Birkeanu is located three kilometers, or about two miles, from the main Auschwitz camp, known as Auschwitz I. To get to the Birkenau camp from the main camp, turn right after exiting from the parking lot. The road curves to the left and goes over the railroad overpass where Reichsführer Heinrich Himmler stood on March 1, 1941 when he selected the village of Birkenau to be the location of a new addition to the Auschwitz camp. At that time, the invasion of the Soviet Union and the plan to exterminate all the Jews in Europe was only months away.
Tactically speaking, once the weakest area of defence is identified, tactical bombers would strike at logistical, communication, and supply targets while field and self-propelled artillery units struck at defence installations. These bombardments were then pre-ceded by probing attacks and smoke screens to conceal the main armoured spearhead, and once the main armoured force broke through the designated strike area, motorized infantry would then fan out behind the armoured spearhead to capture or destroy any enemy forces encircled by panzer and mechanized infantry units or tactically important objectives like bridges, airfields, supply depots, rail yards, naval ports, anti-aircraft batteries, and radar installations.

"Blitzkrieg" is a German compound meaning "lightning war". The word did not enter official terminology of the Wehrmacht either before or during the war, even though it was already used in the military Journal "Deutsche Wehr" in 1935, in the context of an article on how states with insufficient food and raw materials supply can win a war. Another appearance is in 1938 in the "Militär-Wochenblatt", where Blitzkrieg is defined as a "strategic attack", carried out by operational use of tanks, air force, and airborne troops. Karl-Heinz Frieser in his book 'Blitzkrieg Legende', who researched the origin of the term and found the above examples, points out that the pre-war use of the term is rare, and that it practically never entered official terminology throughout the war.

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:
British theorists J.F.C. Fuller and Captain B. H. Liddell Hart have often been associated with blitzkrieg's development, though this is a matter of controversy. The British War Office did permit an Experimental Mechanised Force, formed on 1 May 1927, that was wholly motorized including self propelled artillery and motorised engineers. It is argued that Guderian, a critical figure in blitzkrieg's conception, drew some of his inspiration from Liddell Hart. This was based on a paragraph in the English edition of Guderian's autobiography in which he credits Liddell Hart. In opposition, it is argued that Liddell Hart, as editor of the autobiography's English edition, wrote that paragraph himself or, more broadly, that his influence on Guderian was not as significant as held. Fuller's influence is less clear. During the war, he developed plans for massive, independent tank operations and was subsequently studied by the German leadership. It is variously argued that Fuller's wartime plans and post-war writings were an inspiration, or that his readership was low and German experiences during the war received more attention.
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.

Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]

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]

In 1942, fifteen Nazi leaders met at a conference in Wannsee, Germany to discuss the “Jewish Question”. Their job was to decide the most efficient way to exterminate the Jews. They decided that Jews would be sent to extermination camps where they would be sent to showers. But instead of water coming out of the faucet, they faced their death when poisonous Zyklon-B gas leaked through the showerheads to suffocate them. This decision at the conference is called the “Final Solution.”
The concepts associated with the term blitzkrieg—deep penetrations by armour, large encirclements, and combined arms attacks—were largely dependent upon terrain and weather conditions. Where the ability for rapid movement across "tank country" was not possible, armoured penetrations often were avoided or resulted in failure. Terrain would ideally be flat, firm, unobstructed by natural barriers or fortifications, and interspersed with roads and railways. If it were instead hilly, wooded, marshy, or urban, armour would be vulnerable to infantry in close-quarters combat and unable to break out at full speed.[citation needed] Additionally, units could be halted by mud (thawing along the Eastern Front regularly slowed both sides) or extreme snow. Operation Barbarossa helped confirm that armour effectiveness and the requisite aerial support were dependent on weather and terrain.[68] It should however be noted that the disadvantages of terrain could be nullified if surprise was achieved over the enemy by an attack through areas considered natural obstacles, as occurred during the Battle of France when the German blitzkrieg-style attack went through the Ardennes.[69] Since the French thought the Ardennes unsuitable for massive troop movement, particularly for tanks, they were left with only light defences which were quickly overrun by the Wehrmacht. The Germans quickly advanced through the forest, knocking down the trees the French thought would impede this tactic.[70]
Initially the new facilities were "underutilized". From April 1943 to March 1944, "only" 160,000 Jews were killed at Birkenau, but from March 1944 to November 1944, when all the other death camps had been abandoned, Birkenau surpassed all previous records for mass killing. The Hungarian deportations and the liquidation of the remaining Polish ghettos, such as Lodz, resulted in the gassing of 585,000 Jews. This period made Auschwitz-Birkenau into the most notorious killing site of all time.
In fall 1941, the Nazis began transporting Jews out of the ghetto. Most of them were sent to the Bełżec extermination camp and killed.[45] On 13 March 1943, the ghetto was liquidated and those still fit for work were sent to the new concentration camp at Płaszów.[46] Several thousand not deemed fit for work were sent to extermination camps and killed. Hundreds more were killed on the streets by the Nazis as they cleared out the ghetto. Schindler, aware of the plans because of his Wehrmacht contacts, had his workers stay at the factory overnight to prevent them coming to harm.[47] Schindler witnessed the liquidation of the ghetto and was appalled. From that point forward, says Schindlerjude Sol Urbach, Schindler "changed his mind about the Nazis. He decided to get out and to save as many Jews as he could."[48]
