The Allied offensive in central France, spearheaded by armored units from George S. Patton's Third Army, used breakthrough and penetration techniques that were essentially identical to Guderian's prewar "armoured idea." Patton acknowledged that he had read both Guderian and Rommel before the war, and his tactics shared the traditional cavalry emphasis on speed and attack. A phrase commonly used in his units was "haul ass and bypass."
Born in Baden-Baden in 1900, SS Obersturmbannführer Rudolf Höss became the first commandant of Auschwitz when the camp was founded in April 1940, living with his wife and children in a villa just outside the camp grounds. Appointed by Heinrich Himmler, he served until 11 November 1943, when he became director of Office DI of the SS-Wirtschafts-und Verwaltungshauptamt (SS Business and Administration Head Office or WVHA) in Oranienburg. This post made Höss deputy of the Concentration Camps Inspectorate, under SS-Gruppenführer Richard Glücks. He returned to Auschwitz between 8 May and 29 July 1944 as commander of the SS garrison (Standortältester) to oversee the arrival of Hungary's Jews, a post that made him the superior officer of all the commandants of the Auschwitz camps.
Allied air superiority became a significant hindrance to German operations during the later years of the war. Early German successes enjoyed air superiority with unencumbered movement of ground forces, close air support, and aerial reconnaissance. However, the Western Allies' air-to-ground aircraft were so greatly feared out of proportion to their actual tactical success, that following the lead up to Operation Overlord German vehicle crews showed reluctance to move en masse during daylight. Indeed, the final German blitzkrieg operation in the west, Operation Wacht am Rhein, was planned to take place during poor weather which grounded Allied aircraft. Under these conditions, it was difficult for German commanders to employ the "armoured idea" to its envisioned potential.
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.
His tasks for the Abwehr included collecting information on railways, military installations, and troop movements, as well as recruiting other spies within Czechoslovakia, in advance of a planned invasion of the country by Nazi Germany. He was arrested by the Czech government for espionage on 18 July 1938 and immediately imprisoned, but was released as a political prisoner under the terms of the Munich Agreement, the instrument under which the Czech Sudetenland was annexed into Germany on 1 October. Schindler applied for membership in the Nazi Party on 1 November and was accepted the following year.
