As Nazi tyranny spread across Europe, the Germans and their collaborators persecuted and murdered millions of other people. Between two and three million Soviet prisoners of war were murdered or died of starvation, disease, neglect, or brutal treatment. The Germans targeted the non-Jewish Polish intelligentsia for killing, and deported millions of Polish and Soviet civilians for forced labor in Germany or in occupied Poland, where these individuals worked and often died under deplorable conditions.
Innovators such as Heinz Guderian and Erich von Manstein recognised that the protection given by tanks increased the ability of the German army to manoeuvre in the face of enemy artillery, and that this enhanced speed and mobility. However, the modern technology was merely used to enhance the capabilities that had already been provided, thanks to the army's strategic doctrine.
Himmler ordered the closure of ghettos in Poland in mid-July 1942; most inhabitants were sent to extermination camps. Those Jews needed for war production would be confined in concentration camps.[220] The deportations from the Warsaw Ghetto began on 22 July; over the almost two months of the Aktion, until 12 September, the population was reduced from 350,000 to 65,000. Those deported were transported in freight trains to the Treblinka extermination camp.[221] Similar deportations happened in other ghettos, with many ghettos totally emptied.[222] The first ghetto uprisings occurred in mid-1942 in small community ghettos.[223] Although there were armed resistance attempts in both the larger and smaller ghettos in 1943, in every case they failed against the overwhelming German military force, and the remaining Jews were either killed or deported to the death camps.[224]
Schindler’s profits were extraordinarily high because he used low-paid Jewish workers from the ghetto the Nazis established in the city. During the war, many industrialists like Schindler used the forced labor of Jews living in Nazi ghettos or concentration camps. Major German companies, including Volkswagen, Bayer, and IG Farben, the largest chemical company in the world at the time, profited handsomely from coerced labor. This labor often occurred in the worst conditions possible, and many workers died as a result of being subjected to excessively long, arduous work shifts without adequate food.
The wounds of the Holocaust–known in Hebrew as Shoah, or catastrophe–were slow to heal. Survivors of the camps found it nearly impossible to return home, as in many cases they had lost their families and been denounced by their non-Jewish neighbors. As a result, the late 1940s saw an unprecedented number of refugees, POWs and other displaced populations moving across Europe.

The Germans did not achieve surprise and were not able to outflank or break through into enemy rear areas during the operation.[103] Several historians assert that Operation Citadel was planned and intended to be a blitzkrieg operation.[i] Many of the German participants who wrote about the operation after the war, including Manstein, make no mention of blitzkrieg in their accounts.[j] In 2000, Niklas Zetterling and Anders Frankson characterised only the southern pincer of the German offensive as a "classical blitzkrieg attack".[104] Pier Battistelli wrote that the operational planning marked a change in German offensive thinking away from blitzkrieg and that more priority was given to brute force and fire power than to speed and manoeuvre.[105]
Among the key revelations in Crowe’s book: Oskar Schindler did not write out a list of people to save, he didn’t break down in tears because he thought he could have saved more people, and it is unlikely he experienced a defining moment, such as seeing a girl in a red coat, that led to his decision to save the lives of his Jewish workers. Steven Spielberg’s movie Schindler’s List, while important, impressive and admirable in many ways, took creative license on these and other issues.
According to Dr. Mordecai Paldiel, the head of the Righteous Among the Nations Department at Yad Vashem: “There was no person more deserving of Righteous Gentile status than Oskar Schindler, including Raoul Wallenberg.” Crowe agrees. “I think that Oskar Schindler’s heroism is unique because of the fact that what he did, both in Krakow and Brunnlitz, took place in the midst of the most horrible killing center in modern history. Moreover, while his most dramatic efforts took place during the last year of the war, Oskar Schindler’s efforts to help and later save Jews was a stance that evolved over three or four years.”
German volunteers first used armour in live field conditions during the Spanish Civil War of 1936. Armour commitment consisted of Panzer Battalion 88, a force built around three companies of Panzer I tanks that functioned as a training cadre for Nationalists. The Luftwaffe deployed squadrons of fighters, dive bombers and transport aircraft as the Condor Legion.[77] Guderian said that the tank deployment was "on too small a scale to allow accurate assessments to be made."[78] The true test of his "armoured idea" would have to wait for the Second World War. However, the Luftwaffe also provided volunteers to Spain to test both tactics and aircraft in combat, including the first combat use of the Stuka.[79]
In November, attacks erupted against Jewish businesses. At least 91 Jews died and 267 synagogues were destroyed in a centrally coordinated plot passed off as spontaneous violence across Germany. Thousands of Jews were sent to concentration camps and were only released if they agreed to leave the Nazi territory. Many Jews decided to flee, though options were limited. Britain agreed to house Jewish children, eventually taking in 10,000 minors, but refused to change its policy for Jewish adults.
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]
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.

The Gestapo arrested him several times and interrogated him on charges of irregularities and of favoring Jews. However, Schindler would not desist. In 1943, at the invitation of the American Jewish Joint Distribution Committee, he undertook a highly risky journey to Budapest, where he met with two representatives of Hungarian Jewry. He reported to them about the desperate plight of the Jews in Poland and discussed possible ways of relief.
For historical generals, from Alexander the Great of ancient Macedonia to Frederick II of 18th-century Prussia, their armies functioned as the centre of gravity. If the army was destroyed, the commander would be considered a failure. In smaller countries or countries engaged in internal strife, according to Clausewitz’s reasoning, the capital becomes the centre of gravity and should be identified as the Schwerpunkt. Beginning in the 20th century, technological advances such as radio, aircraft, and motorized vehicles allowed a commander to concentrate force at the Schwerpunkt so as to annihilate the opposition and achieve victory. During World War II each blitzkrieg campaign contained a Schwerpunkt that gave it meaning and substance, with doctrines of mobile warfare expounded by British military theorists J.F.C. Fuller and Sir Basil Liddell Hart providing the tactics necessary to translate the theory into action.
After their defeat in 1918, German military intellectuals began reshaping the army. Under the direction of Hans von Seeckt, commanders fashioned the doctrine that the Wehrmacht was to employ in World War Two. Repelled by the waste and indecisiveness of trench warfare, they returned to the ideas of Schlieffen, and in 1921 the army published its new doctrine, Command and Combat with Combined Arms.
The people in the houses were rudely awoken by the din of our tanks, the clatter and roar of tracks and engines. Troops lay bivouacked beside the road, military vehicles stood parked in farmyards and in some places on the road itself. Civilians and French troops, their faces distorted with terror, lay huddled in the ditches, alongside hedges and in every hollow beside the road. We passed refugee columns, the carts abandoned by their owners, who had fled in panic into the fields. On we went, at a steady speed, towards our objective. Every so often a quick glance at the map by a shaded light and a short wireless message to Divisional H.Q. to report the position and thus the success of 25th Panzer Regiment. Every so often a look out of the hatch to assure myself that there was still no resistance and that contact was being maintained to the rear. The flat countryside lay spread out around us under the cold light of the moon. We were through the Maginot Line! It was hardly conceivable. Twenty-two years before we had stood for four and a half long years before this self-same enemy and had won victory after victory and yet finally lost the war. And now we had broken through the renowned Maginot Line and were driving deep into enemy territory. It was not just a beautiful dream. It was reality."
October 16, 1946 - Göring commits suicide two hours before the scheduled execution of the first group of major Nazi war criminals at Nuremberg. During his imprisonment, a (now repentant) Hans Frank states, "A thousand years will pass and the guilt of Germany will not be erased." Frank and the others are hanged and the bodies are brought to Dachau and burned (the final use of the crematories there) with the ashes then scattered into a river.

^ 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.
On 1 August 1940, Governor-General Hans Frank issued a decree requiring all Kraków Jews to leave the city within two weeks. Only those who had jobs directly related to the German war effort would be allowed to stay. Of the 60,000 to 80,000 Jews then living in the city, only 15,000 remained by March 1941. These Jews were then forced to leave their traditional neighbourhood of Kazimierz and relocate to the walled Kraków Ghetto, established in the industrial Podgórze district.[41][42] Schindler's workers travelled on foot to and from the ghetto each day to their jobs at the factory.[43] Enlargements to the facility in the four years Schindler was in charge included the addition of an outpatient clinic, co-op, kitchen, and dining room for the workers, in addition to expansion of the factory and its related office space.[44]
