The British methods induced "strategic paralysis" among the Ottomans and led to their rapid and complete collapse.[44] In an advance of 65 miles (105 km), captures were estimated to be "at least 25,000 prisoners and 260 guns."[45] Liddell Hart considered that important aspects of the operation were the extent to which Ottoman commanders were denied intelligence on the British preparations for the attack through British air superiority and air attacks on their headquarters and telephone exchanges, which paralyzed attempts to react to the rapidly deteriorating situation.[38]

The Germans turned again, fighting their way north to secure the coastal ports and annihilate the trapped armies. Miraculously, the German high command called a halt to the advance. The reprieve lasted 48 hours, long enough for the British to defend Dunkirk and evacuate what they could of the Allied armies. The Germans entered Paris on June 14. In a humiliating ceremony on June 22, France signed an armistice with Germany, leaving Britain to carry on the fight alone.

In March 1941, Himmler visited Auschwitz and commanded its enlargement to hold 30,000 prisoners. The location of the camp, practically in the center of German-occupied Europe, and its convenient transportation connections and proximity to rail lines was the main thinking behind the Nazi plan to enlarge Auschwitz and begin deporting people here from all over Europe.

Although effective in quick campaigns against Poland and France, mobile operations could not be sustained by Germany in later years. Strategies based on manoeuvre have the inherent danger of the attacking force overextending its supply lines, and can be defeated by a determined foe who is willing and able to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front (as opposed to, for example, the Dutch who had no territory to sacrifice). Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks.[75] As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing and blockade. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.[76]

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.
A major tool of the Nazis' propaganda assault was the weekly Nazi newspaper Der Stürmer (The Attacker). At the bottom of the front page of each issue, in bold letters, the paper proclaimed, "The Jews are our misfortune!" Der Stürmer also regularly featured cartoons of Jews in which they were caricatured as hooked-nosed and ape­like. The influence of the newspaper was far-reaching: by 1938 about a half million copies were distributed weekly.
The Roma refer to the genocide of the Romani people as the Pořajmos.[414] Because they are traditionally a private people with a culture based on oral history, less is known about their experience than that of any other group.[415] Bauer writes that this can be attributed to the Roma's distrust and suspicion, and to their humiliation because some of the taboos in Romani culture regarding hygiene and sex were violated at Auschwitz.[416] In May 1942, the Roma were placed under similar laws to the Jews. On 16 December 1942, Himmler issued a decree that "Gypsy Mischlinge [mixed breeds], Roma Gypsies, and members of the clans of Balkan origins who are not of German blood" should be sent to Auschwitz, unless they had served in the Wehrmacht.[417] He adjusted the order on 15 November 1943; in the occupied Soviet areas, "sedentary Gypsies and part-Gypsies are to be treated as citizens of the country. Nomadic Gypsies and part-Gypsies are to be placed on the same level as Jews and placed in concentration camps."[418] Bauer argues that this adjustment reflected Nazi ideology that the Roma, originally an Aryan population, had been "spoiled" by non-Romani blood.[419]
SS officers, including the infamous Dr. Josef Mengele, would conduct selections among these lines, sending most victims to one side and thus condemning them to death in the gas chambers. A minority was sent to the other side, destined for forced labor. Those who were sent to their deaths were killed that same day and their corpses were burnt in the crematoria. Those not sent to the gas chambers were taken to “quarantine,” where their hair was shaved, striped prison uniforms distributed, and registration took place. Prisoners’ individual registration numbers were tattooed onto their left arm.
From 1933 until 1938, most of the people held in concentration camps were political prisoners and people the Nazis labeled as "asocial." These included the disabled, the homeless, and the mentally ill. After Kristallnacht in 1938, the persecution of Jews became more organized. This led to the exponential increase in the number of Jews sent to concentration camps.

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."

Fuller and Liddell Hart were "outsiders": Liddell Hart was unable to serve as a soldier after 1916 after being gassed on the Somme and Fuller's abrasive personality resulted in his premature retirement in 1933.[149] Their views had limited impact in the British army; the War Office permitted the formation of an Experimental Mechanized Force on 1 May 1927, composed of tanks, lorried infantry, self-propelled artillery and motorised engineers but the force was disbanded in 1928 on the grounds that it had served its purpose. A new experimental brigade was intended for the next year and became a permanent formation in 1933, during the cuts of the 1932/33–1934/35 financial years.[150]

In addition to workers, Schindler moved 250 wagon loads of machinery and raw materials to the new factory.[68] Few if any useful artillery shells were produced at the plant. When officials from the Armaments Ministry questioned the factory's low output, Schindler bought finished goods on the black market and resold them as his own.[69] The rations provided by the SS were insufficient to meet the needs of the workers, so Schindler spent most of his time in Kraków, obtaining food, armaments, and other materials. His wife Emilie remained in Brünnlitz, surreptitiously obtaining additional rations and caring for the workers' health and other basic needs.[70][71] Schindler also arranged for the transfer of as many as 3,000 Jewish women out of Auschwitz to small textiles plants in the Sudetenland in an effort to increase their chances of surviving the war.[72][73]
Dr. Adelaide Hautval was a French Psychiatrist who protested against the treatment of Jews. In 1943 she was sent to Auschwitz-Birkenau where she used her medical knowledge to treat Jewish women inmates suffering typhus and other diseases. She became known as ‘The Saint’. Dr Joseph Mengele ordered Hautval to operate on Jewish twins as part of his experiments. She refused, but was given no further punishment. Adelaide Hautval was liberated in Auschwitz in January 1945.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
