The core principle behind Blitzkrieg was to concentrate the force on a single point. The German called this penetration or breakthrough, and its purpose was to rupture enemy defenses. The main objective: apply overwhelming force at a weak point in the enemy line to force an opening. This opening functions as the first stage of tactical deep battle in its Blitzkrieg form, and it was so effective that the Germans often referred to it as “the beginning of the end”.
John Ellis wrote that "...there is considerable justice in Matthew Cooper's assertion that the panzer divisions were not given the kind of strategic mission that was to characterize authentic armoured blitzkrieg, and were almost always closely subordinated to the various mass infantry armies." Steven Zaloga wrote, "Whilst Western accounts of the September campaign have stressed the shock value of the panzer and Stuka attacks, they have tended to underestimate the punishing effect of German artillery on Polish units. Mobile and available in significant quantity, artillery shattered as many units as any other branch of the Wehrmacht."
As Soviet armies advanced in 1944 and early 1945, Auschwitz was gradually abandoned. On January 18, 1945, some 60,000 prisoners were marched to Wodzisław Śląski, where they were put on freight trains (many in open cars) and sent westward to concentration camps away from the front. One in four died en route from starvation, cold, exhaustion, and despair. Many were shot along the way in what became known as the “death marches.” The 7,650 sick or starving prisoners who remained were found by arriving Soviet troops on January 27, 1945.
The Reichswehr and the Red Army began a secret collaboration in the Soviet Union to evade the Treaty of Versailles occupational agent, the Inter-Allied Commission. In 1926, War games and tests were begun at Kazan and Lipetsk. The centres were used to field test aircraft and armoured vehicles up to the battalion level and housed aerial and armoured warfare schools, through which officers were rotated.
The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...
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.
