Historian Victor Davis Hanson states that Blitzkrieg "played on the myth of German technological superiority and industrial dominance," adding that German successes, particularly that of its Panzer divisions were "instead predicated on the poor preparation and morale of Germany's enemies." Hanson also reports that at a Munich public address in November 1941, Hitler had "disowned" the concept of Blitzkrieg by calling it an "idiotic word." Further, successful Blitzkrieg operations were predicated on superior numbers, air-support, and were only possible for short periods of time without sufficient supply lines. For all intents and purposes, Blitzkrieg ended at the Eastern Front once the German forces gave up Stalingrad, after they faced hundreds of new T-34 tanks, when the Luftwaffe became unable to assure air dominance, and following the stalemate at Kursk—to this end, Hanson concludes that German military success was not accompanied by the adequate provisioning of its troops with food and materiel far from the source of supply, which contributed to its ultimate failures. Despite its later disappointments as German troops extended their lines at too great a distance, the very specter or armored Blitzkrieg forces initially proved victorious against Polish, Dutch, Belgian, and French armies early in the war.
He began by turning his factory into an official subcamp of a newly constructed labor camp at Plazów. For a time, it was a haven for about 500 Jews. Then, in the fall of 1944, the Nazis ordered both camps closed and all workers shipped to Auschwitz, a killing center. Schindler refused to let that happen. He put together a list of 1,100 men, women, and children that he claimed as his workers. He then used his money and influence to transport those workers to a new factory he was building at Brinnlitz, Czechoslovakia. When the Jewish women who worked in his factory were transported to Auschwitz by mistake, he accomplished the impossible: he managed to get the women back by offering Nazi officials a fortune in bribes.
Marked by fierce close quarters combat and direct assaults on civilians in air raids, it is often regarded as the single largest (nearly 2.2 million personnel) and bloodiest (1.8–2 million killed, wounded or captured) battle in the history of warfare. It was an extremely costly defeat for German forces, and the Army High Command had to withdraw vast military forces from the West to replace their losses.
Blitzkrieg is vulnerable to an enemy that is robust enough to weather the shock of the attack and that does not panic at the idea of enemy formations in its rear area. This is especially true if the attacking formation lacks the reserve to keep funnelling forces into the spearhead, or lacks the mobility to provide infantry, artillery and supplies into the attack. If the defender can hold the shoulders of the breach they will have the opportunity to counter-attack into the flank of the attacker, potentially cutting off the van as happened to Kampfgruppe Peiper in the Ardennes.
The most ambitious uprising at Auschwitz-Birkenau involved the actions of 250 Jewish Sonderkommando on 7 October 1944. They set fire to one of the crematoria. They managed to cut through the fence and reach the outside of the camp. The SS surrounded them. In the fight that followed, they managed to kill three SS guards and wound ten of them. All 250 Jews were killed.
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.
Despite the term blitzkrieg being coined during the Invasion of Poland of 1939, historians generally hold that German operations during it were more consistent with more traditional methods. The Wehrmacht's strategy was more inline with Vernichtungsgedanken, or a focus on envelopment to create pockets in broad-front annihilation. Panzer forces were deployed among the three German concentrations without strong emphasis on independent use, being used to create or destroy close pockets of Polish forces and seize operational-depth terrain in support of the largely un-motorized infantry which followed. The Luftwaffe gained air superiority by a combination of superior technology and numbers. Common claims that the Polish Air Force was destroyed early in the campaign while it was on the ground are not true. Polish aircraft were moved to hidden airstrips approximately 48 hours before the outbreak of the hostilities.
Guderian argued that the tank would be the decisive weapon of the next war. "If the tanks succeed, then victory follows", he wrote. In an article addressed to critics of tank warfare, he wrote "until our critics can produce some new and better method of making a successful land attack other than self-massacre, we shall continue to maintain our beliefs that tanks—properly employed, needless to say—are today the best means available for land attack." Addressing the faster rate at which defenders could reinforce an area than attackers could penetrate it during the First World War, Guderian wrote that "since reserve forces will now be motorized, the building up of new defensive fronts is easier than it used to be; the chances of an offensive based on the timetable of artillery and infantry co-operation are, as a result, even slighter today than they were in the last war." He continued, "We believe that by attacking with tanks we can achieve a higher rate of movement than has been hitherto obtainable, and—what is perhaps even more important—that we can keep moving once a breakthrough has been made."[l] Guderian additionally required that tactical radios be widely used to facilitate coordination and command by having one installed in all tanks.

After Germany's failure to destroy the Soviets before the winter of 1941, the limits of German tactical superiority became apparent. Although the German invasion successfully conquered large areas of Soviet territory, the overall strategic effects were more limited. The Red Army was able to regroup far to the rear of the main battle line, and eventually defeat the German forces for the first time in the Battle of Moscow.
The logistics of the mass murder turned Germany into what Michael Berenbaum called a "genocidal state". Eberhard Jäckel wrote in 1986 that it was the first time a state had thrown its power behind the idea that an entire people should be wiped out.[h] Anyone with three or four Jewish grandparents was to be exterminated, and complex rules were devised to deal with Mischlinge ("mixed breeds": half and quarter Jews). Bureaucrats identified who was a Jew, confiscated property, and scheduled trains to deport them. Companies fired Jews and later used them as slave labor. Universities dismissed Jewish faculty and students. German pharmaceutical companies tested drugs on camp prisoners; other companies built the crematoria. As prisoners entered the death camps, they were ordered to surrender all personal property, which was catalogued and tagged before being sent to Germany for reuse or recycling. Through a concealed account, the German National Bank helped launder valuables stolen from the victims.
The first mass transport to Auschwitz I, which included Catholic prisoners, suspected members of the Polish resistance, and 20 Jews, arrived on 14 June 1940 from prison in Tarnów, Poland. They were interned in the former building of the Polish Tobacco Monopoly, adjacent to the site, until the camp was ready. By the end of 1940, the SS had confiscated land around the camp to create a 40-square-kilometre (15 sq mi) "zone of interest" surrounded by a double ring of electrified barbed wire fences and watchtowers. The inmate population grew quickly as the camp absorbed Poland's intelligentsia and dissidents. By March 1941, 10,900 were imprisoned there, most of them Poles.
Eight hundred to a thousand people were crammed into the superimposed compartments of each barracks. Unable to stretch out completely, they slept there both lengthwise and crosswise, with one man's feet on another's head, neck, or chest. Stripped of all human dignity, they pushed and shoved and bit and kicked each other in an effort to get a few more inches' space on which to sleep a little more comfortably. For they did not have long to sleep.
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.
After some time off to recover in Zwittau, Schindler was promoted to second in command of his Abwehr unit and relocated with his wife to Ostrava, on the Czech-Polish border, in January 1939. He was involved in espionage in the months leading up to Hitler's seizure of the remainder of Czechoslovakia in March. Emilie helped him with paperwork, processing and hiding secret documents in their apartment for the Abwehr office. As Schindler frequently travelled to Poland on business, he and his 25 agents were in a position to collect information about Polish military activities and railways for the planned invasion of Poland. One assignment called for his unit to monitor and provide information about the railway line and tunnel in the Jablunkov Pass, deemed critical for the movement of German troops. Schindler continued to work for the Abwehr until as late as fall 1940, when he was sent to Turkey to investigate corruption among the Abwehr officers assigned to the German embassy there.
