Blitzkrieg tactics were used in the successful German invasions of Belgium, the Netherlands, and France in 1940, which saw audacious applications of air power and airborne infantry to overcome fixed fortifications that were believed by the defenders to be impregnable. The Kesselschlacht campaigns on the Eastern Front were staggering in scale, with Kessels that covered vast swathes of territory, enveloping hundreds of thousands of troops. Blitzkrieg tactics were also used by the German commander Erwin Rommel during the desert campaigns in North Africa.
There have been protracted disputes over the perceived Christianization of the site. Pope John Paul II celebrated mass over the train tracks leading to Auschwitz II-Birkenau on 7 June 1979, and called the camp "the Golgotha of our age", referring to the crucifixion of Jesus. More controversy followed when Carmelite nuns founded a convent in 1984 in a former theater outside the camp's perimeter, near block 11 of Auschwitz I, after which a local priest and some survivors erected a large cross—one that had been used during the pope's mass—behind block 11 to commemorate 152 Polish inmates shot by the Germans in 1941. After a long dispute, Pope John Paul II intervened, and the nuns moved the convent elsewhere in 1993. The cross remained, triggering the "War of the Crosses", as more crosses were erected to commemorate Christian victims, despite international objections. The Polish government and Catholic Church eventually agreed to remove all but the original.
At the outbreak of war, the German army had no radically new theory of war. The operational thinking of the German army had not changed significantly since the First World War or since the late 19th century. J. P. Harris and Robert M. Citino point out that the Germans had always had a marked preference for short, decisive campaigns – but were unable to achieve short-order victories in First World War conditions. The transformation from the stalemate of the First World War into tremendous initial operational and strategic success in the Second, was partly the employment of a relatively small number of mechanised divisions, most importantly the Panzer divisions, and the support of an exceptionally powerful air force.
Meanwhile, beginning in the fall of 1939, Nazi officials selected around 70,000 Germans institutionalized for mental illness or disabilities to be gassed to death in the so-called Euthanasia Program. After prominent German religious leaders protested, Hitler put an end to the program in August 1941, though killings of the disabled continued in secrecy, and by 1945 some 275,000 people deemed handicapped from all over Europe had been killed. In hindsight, it seems clear that the Euthanasia Program functioned as a pilot for the Holocaust.
In a blitzkrieg, tanks and troop-transport vehicles were concentrated, and massive attacks by dive bombers were conducted on enemy front-line positions. When these forces had broken through, they continued deep into enemy territory, encircling and cutting off the enemy. The techniques were first developed by the German army late in World War I in an effort to overcome static trench warfare, but the Germans lacked the mobility to succeed. Between the wars, armored tactics were further developed by Basil Liddell Hart and J. F. C. Fuller in Britain, Charles de Gaulle in France, and Heinz Guderian in Germany. Made chief of German mobile troops in 1938, Guderian led the drive across France in 1940.
^ Historian H.P. Willmott writes that, "Many examples of the experiences and losses suffered by German formations moving up to the front are well known. Panzer Lehr, for instance, on 7 June alone lost 84 half-tracks, prime movers and self propelled guns, 40 fuel bowsers, 90 soft-skinned vehicles and five tanks as it made its way from Le Mans to Caen.
That month, Himmler ordered the evacuation of all camps, charging camp commanders with "making sure that not a single prisoner from the concentration camps falls alive into the hands of the enemy". Beginning on 17 January, 56,000–58,000 Auschwitz detainees—over 20,000 from Auschwitz I and II, over 30,000 from subcamps, and two-thirds of them Jews—were evacuated under guard, largely on foot, in severe winter conditions, heading west. Around 2,200 were evacuated by rail from two subcamps; fewer than 9,000 were left behind, deemed too sick to move. During the marches, camp staff shot anyone too sick or exhausted to continue, or anyone stopping to urinate or tie a shoelace. SS officers walked behind the marchers killing anyone lagging behind who had not already been shot. Peter Longerich estimates that a quarter of the detainees were thus killed. Those who managed to walk to Wodzisław Śląski and Gliwice were sent on open freight cars, without food, to concentration camps in Germany: Bergen-Belsen, Buchenwald, Dachau, Flossenburg, Gross-Rosen, Mauthausen, Dora-Mittelbau, Ravensbruck, and Sachsenhausen.
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.
"Blitzkrieg" has since expanded into multiple meanings in more popular usage. From its original military definition, "blitzkrieg" may be applied to any military operation emphasizing the surprise, speed, or concentration stressed in accounts of the Invasion of Poland. During the war, the Luftwaffe terror bombings of London came to be known as The Blitz. Similarly, blitz has come to describe the " blitz" (rush) tactic of American football, and the blitz form of chess in which players are allotted very little time. Blitz or blitzkrieg is used in many other non-military contexts.
Most of the Jewish ghettos of General Government were liquidated in 1942–1943, and their populations shipped to the camps for extermination.[t] About 42,000 Jews were shot during the Operation Harvest Festival on 3–4 November 1943. At the same time, rail shipments arrived regularly from western and southern Europe at the extermination camps. Few Jews were shipped from the occupied Soviet territories to the camps: the killing of Jews in this zone was mostly left in the hands of the SS, aided by locally recruited auxiliaries.[u]
In 2017 a Körber Foundation survey found that 40 percent of 14-year-olds in Germany did not know what Auschwitz was. The following year a survey organized by the Claims Conference, United States Holocaust Memorial Museum and others found that 41 percent of 1,350 American adults surveyed, and 66 percent of millennials, did not know what Auschwitz was, while 22 percent said they had never heard of the Holocaust. A CNN-ComRes poll in 2018 found a similar situation in Europe.
After 1942, the economic functions of the camps, previously secondary to their penal and terror functions, came to the fore. Forced labor of camp prisoners became commonplace. The guards became much more brutal, and the death rate increased as the guards not only beat and starved prisoners, but killed them more frequently. Vernichtung durch Arbeit ("extermination through labor") was a policy—camp inmates would literally be worked to death, or to physical exhaustion, at which point they would be gassed or shot. The Germans estimated the average prisoner's lifespan in a concentration camp at three months, due to lack of food and clothing, constant epidemics, and frequent punishments for the most minor transgressions. The shifts were long and often involved exposure to dangerous materials.
Schindler moved to West Germany after the war, where he was supported by assistance payments from Jewish relief organisations. After receiving a partial reimbursement for his wartime expenses, he moved with his wife, Emilie, to Argentina, where they took up farming. When he went bankrupt in 1958, Schindler left his wife and returned to Germany, where he failed at several business ventures and relied on financial support from Schindlerjuden ("Schindler Jews")—the people whose lives he had saved during the war. He and his wife, Emilie, were named Righteous Among the Nations by the Israeli government in 1993. He died on 9 October 1974 in Hildesheim, Germany, and was buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way.
