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.
Seldom in the history of military thought have such elaborate interpretive structures been built on a more limited foundation. The term blitzkrieg was in fact never used in the title of a German military manual or handbook. Nor is it to be widely found in the memoirs or correspondence of German generals. The word was used in the Wehrmacht during World War II but was commonly considered to be of foreign origin. Guderian wrote in Panzer Leader that “our enemies coined the word.” The first known use of the word blitzkrieg in an English publication occurred in an article in Time magazine in September 25, 1939, discussing the Polish campaign. From there the word came into general circulation as a shorthand description of a form of war that seemed to have no convenient existing frame of reference. From Western sources it expanded into German popular military literature, and from there into history. The transmission process was facilitated by the British theorists J. F. C. Fuller and Basil Liddell Hart, who insisted that their concepts of mobile war were fundamental to the German victories of 1939-1941.
In March 1941, Himmler visited Auschwitz and commanded its enlargement to hold 30,000 prisoners. The location of the camp, practically in the center of German-occupied Europe, and its convenient transportation connections and proximity to rail lines was the main thinking behind the Nazi plan to enlarge Auschwitz and begin deporting people here from all over Europe.
Blitzkrieg's immediate development began with Germany's defeat in the First World War. Shortly after the war, the new Reichswehr created committees of veteran officers to evaluate 57 issues of the war. The reports of these committees formed doctrinal and training publications which were the standards in the Second World War. The Reichswehr was influenced by its analysis of pre-war German military thought, in particular its infiltration tactics of the war, and the maneuver warfare which dominated the Eastern Front.
Schindler grew up in Svitavy, Moravia, and worked in several trades until he joined the Abwehr, the military intelligence service of Nazi Germany, in 1936. He joined the Nazi Party in 1939. Prior to the German occupation of Czechoslovakia in 1938, he collected information on railways and troop movements for the German government. He was arrested for espionage by the Czechoslovak government but was released under the terms of the Munich Agreement in 1938. Schindler continued to collect information for the Nazis, working in Poland in 1939 before the invasion of Poland at the start of World War II. In 1939, Schindler acquired an enamelware factory in Kraków, Poland, which employed at the factory's peak in 1944 about 1,750 workers, of whom 1,000 were Jews. His Abwehr connections helped Schindler protect his Jewish workers from deportation and death in the Nazi concentration camps. As time went on, Schindler had to give Nazi officials ever larger bribes and gifts of luxury items obtainable only on the black market to keep his workers safe.
