At the end of the war, in an effort to remove the traces of the crimes they had committed, the SS began dismantling and razing the gas chambers, crematoria, and other buildings, as well as burning documents. Prisoners capable of marching were evacuated into the depths of the German Reich, and thousands of marchers died of hunger, exhaustion and exposure. Those who remained behind in the camp and survived long enough were liberated by Red Army soldiers on 27 January 1945.

^ Jump up to: a b Dan Stone (Histories of the Holocaust, 2010): "Europe's Romany (Gypsy) population was also the victim of genocide under the Nazis. Many other population groups, notably Poles, Ukrainians, and Soviet prisoners of war were killed in huge numbers, and smaller groups such as Jehovah's Witnesses, Black Germans, and homosexuals suffered terribly under Nazi rule. The evidence suggests that the Slav nations of Europe were also destined, had Germany won the war, to become victims of systematic mass murder; and even the terrible brutality of the occupation in eastern Europe, especially in Poland, can be understood as genocidal according to the definition put forward by Raphael Lemkin in his major study, Axis Rule in Occupied Europe (1944), the book that introduced the term 'genocide' to our vocabulary. Part of the reason for today's understanding, though, is a correct assessment of the fact that for the Nazis the Jews were regarded in a kind of 'metaphysical' way; they were not just considered as racially inferior (like Romanies), deviants (like homosexuals) or enemy nationals standing in the way of German colonial expression (like Slavs). ... [T]he Jews were to some extent outside of the racial scheme as defined by racial philosophers and anthropologists. They were not mere Untermenschen (sub-humans) ... but were regarded as a Gegenrasse: "a 'counter-race', that is to say, not really human at all. ... 'Holocaust', then, refers to the genocide of the Jews, which by no means excludes an understanding that other groups—notably Romanies and Slavs—were victims of genocide. Indeed ... the murder of the Jews, although a project in its own right, cannot be properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans."[32]

According to David A.Grossman, by the 12th Battle of Isonzo (October-November 1917), while conducting a light-infantry operation, Rommel had perfected his maneuver-warfare principles, which were the very same ones that were applied during the Blitzkrieg against France in 1940 (and repeated in the Coalition ground offensive against Iraq in the 1991 Gulf War).[56] During the Battle of France and against his staff advisor's advice, Hitler ordered that everything should be completed in a few weeks; fortunately for the Führer, Rommel and Guderian disobeyed the General Staff's orders (particularly General von Kleist) and forged ahead making quicker progress than anyone expected, and on the way, "inventing the idea of Blitzkrieg."[57] It was Rommel who created the new archetype of Blitzkrieg, leading his division far ahead of flanking divisions.[58] MacGregor and Williamson remark that Rommel's version of Blitzkrieg displayed a significantly better understanding of combined-arms warfare than that of Guderian.[59] General Hoth submitted an official report in July 1940 which declared that Rommel had "explored new paths in the command of Panzer divisions".[60]
To achieve a breakout, armored forces themselves would attack the enemy's defensive line directly, supported by their own infantry (Panzergrenadiers), artillery fire and aerial bombardment in order to create a breach in the enemy's line. Through this breach the tanks could break through without the traditional encumbrance of the slow logistics of a pure infantry regiment. The breaching force never lost time by 'stabilising its flanks' or by regrouping; rather it continued the assault in a towards the interior of the enemies lines, sometimes diagonally across them. This point of breakout has been labeled a "hinge", but only because a change in direction of the defender's lines is naturally weak and therefore a natural target for blitzkrieg assault.
Oskar Schindler was born April 28, 1908, in the city of Svitavy [Zwittau], in the Sudetenland, now part of the Czech Republic. The eldest of two children, Oskar’s father, Hans Schindler, was a farm-equipment manufacturer, his mother, Louisa, was a homemaker. Oscar and his sister, Elfriede, attended a German-language school where he was popular, though not an exceptional student. Forgoing the opportunity to attend college, he went to trade school instead, taking courses in several areas.
The understanding of operations in Poland has shifted considerably since the Second World War. Many early postwar histories incorrectly attribute German victory to "enormous development in military technique which occurred between 1918 and 1940", incorrectly citing that "Germany, who translated (British inter-war) theories into action...called the result Blitzkrieg." More recent histories identify German operations in Poland as relatively cautious and traditional. Matthew Cooper wrote that
From 1933 until 1938, most of the people held in concentration camps were political prisoners and people the Nazis labeled as "asocial." These included the disabled, the homeless, and the mentally ill. After Kristallnacht in 1938, the persecution of Jews became more organized. This led to the exponential increase in the number of Jews sent to concentration camps.
In the first phase of World War II in Europe, Germany sought to avoid a long war. Germany's strategy was to defeat its opponents in a series of short campaigns. Germany quickly overran much of Europe and was victorious for more than two years by relying on a new military tactic called the "Blitzkrieg" (lightning war). Blitzkrieg tactics required the concentration of offensive weapons (such as tanks, planes, and artillery) along a narrow front. These forces would drive a breach in enemy defenses, permitting armored tank divisions to penetrate rapidly and roam freely behind enemy lines, causing shock and disorganization among the enemy defenses. German air power prevented the enemy from adequately resupplying or redeploying forces and thereby from sending reinforcements to seal breaches in the front. German forces could in turn encircle opposing troops and force surrender.

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.
