In 1914, German strategic thinking derived from the writings of Carl von Clausewitz (June 1, 1780 – November 16, 1831), Helmuth von Moltke the Elder (26 October 1800 – 24 April 1891) and Alfred von Schlieffen (28 February 1833 – 4 January 1913), who advocated manoeuvre, mass and envelopment to create the conditions for a decisive battle (Vernichtungsschlacht). During the war, officers such as Willy Rohr developed tactics to restore manoeuvre on the battlefield. Specialist light infantry (Sturmtruppen, "storm troops") were to exploit weak spots to make gaps for larger infantry units to advance with heavier weapons and exploit the success, leaving isolated strong points to troops following up. Infiltration tactics were combined with short hurricane artillery bombardments using massed artillery, devised by Colonel Georg Bruchmüller. Attacks relied on speed and surprise rather than on weight of numbers. These tactics met with great success in Operation Michael, the spring offensive of 1918 and restored temporarily the war of movement, once the Allied trench system had been overrun. The German armies pushed on towards Amiens and then Paris, coming within 120 kilometres (75 mi) before supply deficiencies and Allied reinforcements halted the advance.[27] Historian James Corum criticised the German leadership for failing to understand the technical advances of the First World War, having given tank production the lowest priority and having conducted no studies of the machine gun prior to that war.[28]
The orders for the final evacuation and liquidation of the camp were issued in mid-January 1945. The Germans left behind in the main Auschwitz camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long; the rest, approximately 58,000 people, were evacuated by foot into the depths of the Third Reich.
The photo below shows the railroad siding inside the camp, called the ramp, where the Jews exited from the trains and the selection process took place. Those who were fit for work were allowed to live for a few months, until they inevitably died of disease or overwork. The others were sent immediately to one of the four gas chambers at the far end of the camp. The gas chambers in Krema II and Krema III were at the end of the main camp road, which is shown on the left in the photo below. The railroad tracks extend about a mile into the camp, all the way to the gas chambers II and III; some of the Hungarian Jews were immediately gassed without going through a selection process, even though the Nazis were desperately in need of workers for their munitions factories. This photo was taken in the early morning, looking west from the gate house tower.

Shortly after the outbreak of war in September 1939, thirty-one-year-old Schindler showed up in occupied Krakow. The ancient city, home to some 60,000 Jews and seat of the German occupation administration, the Generalgouvernement, proved highly attractive to German entrepreneurs, hoping to capitalize on the misfortunes of the subjugated country and make a fortune. Naturally cunning and none too scrupulous, Schindler appeared at first to thrive in these surroundings.  In October 1939, he took over a run-down enamelware factory that had previously belonged to a Jew.  He cleverly maneuvered his steps- acting upon the shrewd commercial advice of a Polish-Jewish accountant, Isaak Stern - and began to build himself a fortune. The small concern in Zablocie outside Krakow, which started producing kitchenware for the German army, began to grow by leaps and bounds. After only three months it already had a task-force of some 250 Polish workers, among them seven Jews. By the end of 1942, it had expanded into a mammoth enamel and ammunitions production plant, occupying some 45,000 square meters and employing almost 800 men and women. Of these, 370 were Jews from the Krakow ghetto, which the Germans had established after they entered the city.
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]
The influence of air forces over forces on the ground changed significantly over the course of the Second World War. Early German successes were conducted when Allied aircraft could not make a significant impact on the battlefield. In May 1940, there was near parity in numbers of aircraft between the Luftwaffe and the Allies, but the Luftwaffe had been developed to support Germany's ground forces, had liaison officers with the mobile formations, and operated a higher number of sorties per aircraft.[71] In addition, German air parity or superiority allowed the unencumbered movement of ground forces, their unhindered assembly into concentrated attack formations, aerial reconnaissance, aerial resupply of fast moving formations and close air support at the point of attack.[citation needed] The Allied air forces had no close air support aircraft, training or doctrine.[71] The Allies flew 434 French and 160 British sorties a day but methods of attacking ground targets had yet to be developed; therefore Allied aircraft caused negligible damage. Against these 600 sorties the Luftwaffe on average flew 1,500 sorties a day.[72] On May 13, Fliegerkorps VIII flew 1,000 sorties in support of the crossing of the Meuse. The following day the Allies made repeated attempts to destroy the German pontoon bridges, but German fighter aircraft, ground fire and Luftwaffe flak batteries with the panzer forces destroyed 56 percent of the attacking Allied aircraft while the bridges remained intact.[73]
The early 1950s literature transformed blitzkrieg into a historical military doctrine, which carried the signature of Liddell Hart and Guderian. The main evidence of Liddell Hart's deceit and "tendentious" report of history can be found in his letters to Erich von Manstein, Heinz Guderian and the relatives and associates of Erwin Rommel. Liddell Hart, in letters to Guderian, "imposed his own fabricated version of blitzkrieg on the latter and compelled him to proclaim it as original formula".[145][146] Kenneth Macksey found Liddell Hart's original letters to Guderian in the General's papers, requesting that Guderian give him credit for "impressing him" with his ideas of armoured warfare. When Liddell Hart was questioned about this in 1968 and the discrepancy between the English and German editions of Guderian's memoirs, "he gave a conveniently unhelpful though strictly truthful reply. ('There is nothing about the matter in my file of correspondence with Guderian himself except...that I thanked him...for what he said in that additional paragraph'.)".[147]
April 11 - August 14 - Eichmann on trial in Jerusalem for crimes against the Jewish people, crimes against humanity and war crimes. Found guilty and hanged at Ramleh on May 31, 1962. A fellow Nazi reported Eichmann once said "he would leap laughing into the grave because the feeling that he had five million people on his conscience would be for him a source of extraordinary satisfaction."
By July 1944, Germany was losing the war; the SS began closing down the easternmost concentration camps and deporting the remaining prisoners westward. Many were killed in Auschwitz and the Gross-Rosen concentration camp. Schindler convinced SS-Hauptsturmführer Amon Göth, commandant of the nearby Kraków-Płaszów concentration camp, to allow him to move his factory to Brněnec in the Protectorate of Bohemia and Moravia, thus sparing his workers from almost certain death in the gas chambers. Using names provided by Jewish Ghetto Police officer Marcel Goldberg, Göth's secretary Mietek Pemper compiled and typed the list of 1,200 Jews who travelled to Brünnlitz in October 1944. Schindler continued to bribe SS officials to prevent the execution of his workers until the end of World War II in Europe in May 1945, by which time he had spent his entire fortune on bribes and black market purchases of supplies for his workers.
