Allied air superiority became a significant hindrance to German operations during the later years of the war. By June 1944 the Western Allies had complete control of the air over the battlefield and their fighter-bomber aircraft were very effective at attacking ground forces. On D-Day the Allies flew 14,500 sorties over the battlefield area alone, not including sorties flown over north-western Europe. Against this on 6 June the Luftwaffe flew some 300 sorties. Though German fighter presence over Normandy increased over the next days and weeks, it never approached the numbers the Allies commanded. Fighter-bomber attacks on German formations made movement during daylight almost impossible. Subsequently, shortages soon developed in food, fuel and ammunition, severely hampering the German defenders. German vehicle crews and even flak units experienced great difficulty moving during daylight.[g] Indeed, the final German offensive operation in the west, Operation Wacht am Rhein, was planned to take place during poor weather to minimize interference by Allied aircraft. Under these conditions it was difficult for German commanders to employ the "armoured idea", if at all.[citation needed]

In the summer of 1942, Germany launched another offensive in the southern USSR against Stalingrad and the Caucasus, the Soviets again lost tremendous amounts of territory, only to counter-attack once more during winter. German gains were ultimately limited by Hitler diverting forces from the attack on Stalingrad and driving towards the Caucasus oilfields simultaneously. The Wehrmacht became overstretched, although winning operationally, it could not inflict a decisive defeat as the durability of the Soviet Union's manpower, resources, industrial base and aid from the Western Allies began to take effect.[95]
In 1988, West Germany allocated another $125 million for reparations. Companies such as BMW, Deutsche Bank, Ford, Opel, Siemens, and Volkswagen faced lawsuits for their use of forced labor during the war.[463] In response, Germany set up the "Remembrance, Responsibility and Future" Foundation in 2000, which paid €4.45 billion to former slave laborers (up to €7,670 each).[465] In 2013, Germany agreed to provide €772 million to fund nursing care, social services, and medication for 56,000 Holocaust survivors around the world.[466] The French state-owned railway company, the SNCF, agreed in 2014 to pay $60 million to Jewish-American survivors, around $100,000 each, for its role in the transport of 76,000 Jews from France to extermination camps between 1942 and 1944.[467]
Conventional wisdom traces blitzkrieg, “lightning war,” to the development in Germany between 1918 and 1939 of a body of doctrine using mobility to prevent repetition of the attritional deadlock of World War I. Soldiers such as Hans von Seeckt and Heinz Guderian allegedly perceived more clearly than their counterparts elsewhere in Europe the military potential of the internal-combustion engine combined with modern communications technology. Large formations moving on tracks and wheels, directed by radios, could rupture an enemy’s front and so disorganize its rear that countermeasures would be paralyzed. First tested in Poland, the concept reached perihelion in France and the Low Countries in 1940, when in less than six weeks the German army crushed the combined forces of four nations. Applied a year later against the Soviet Union, blitzkrieg purportedly brought the Wehrmacht to the gates of Moscow in six months. Some accounts insist that only Adolf Hitler’s incompetent interference tipped the war’s balance so far against Germany that even blitzkrieg’s most sophisticated refinements could do no more than stave off the Reich’s collapse.
Soon after his marriage, Schindler quit working for his father and took a series of jobs, including a position at Moravian Electrotechnic and the management of a driving school. After an 18-month stint in the Czech army, where he rose to the rank of Lance-Corporal in the Tenth Infantry Regiment of the 31st Army, Schindler returned to Moravian Electrotechnic, which went bankrupt shortly afterwards. His father's farm machinery business closed around the same time, leaving Schindler unemployed for a year. He took a job with Jarslav Simek Bank of Prague in 1931, where he worked until 1938.[4]
