Blitzkrieg was very effective against static defense doctrines that most countries developed in the aftermath of the First World War. Early attempts to defeat the blitzkrieg can be dated to the Invasion of Poland in 1939, where Polish general Stanisław Maczek, commander of 10th Motorized Cavalry Brigade, prepared a detailed report of blitzkrieg tactics, its usage, effectiveness and possible precautions for the French military from his experiences. However, the French staff disregarded this report (it was captured, unopened, by the German army). Later, Maczek would become one of the most successful Allied armoured forces commanders in the war.
After invading Poland, the Germans established ghettos in the incorporated territories and General Government to confine Jews. The ghettos were formed and closed off from the outside world at different times and for different reasons. For example, the Łódź ghetto was closed in April 1940, to force the Jews inside to give up money and valuables; the Warsaw ghetto was closed for health considerations (for the people outside, not inside, the ghetto), but this did not happen until November 1940; and the Kraków ghetto was not established until March 1941. The Warsaw Ghetto contained 380,000 people and was the largest ghetto in Poland; the Łódź Ghetto was the second largest, holding between 160,000 to 223,000. Because of the long drawn-out process of establishing ghettos, it is unlikely that they were originally considered part of a systematic attempt to eliminate Jews completely.
Hitler’s worldview revolved around two concepts: territorial expansion (that is, greater Lebensraum—“living space”—for the German people) and racial supremacy. After World War I the Allies denied Germany colonies in Africa, so Hitler sought to expand German territory and secure food and resources—scarce during World War I—in Europe itself. Hitler viewed the Jews as racial polluters, a cancer on German society in what has been termed by Holocaust survivor and historian Saul Friedländer “redemptive anti-Semitism,” focused on redeeming Germany from its ills and ridding it of a cancer on the body politic. Historian Timothy Snyder characterized the struggle as even more elemental, as “zoological,” and “ecological,” a struggle of the species. Hitler opposed Jews for the values they brought into the world. Social justice and compassionate assistance to the weak stood in the way of what he perceived as the natural order, in which the powerful exercise unrestrained power. In Hitler’s view, such restraint on the exercise of power would inevitably lead to the weakening, even the defeat, of the master race.
I've been to Auschwitz Birkenau. On a cold November day I stood at the spot where the "selections" were made. Large snowflakes fell out the the gray somber sky, and skeletal poplars or other similar trees stood in the distance. I was chilled to the bone with a coldness that did not leave me until long after I reboarded the heated bus that took me back to Krakow. Every civilized person should go there and see how apparently civilized people conducted the most inhumane and uncivilized rituals in all of recorded history.
The requirement for focus of this offense-oriented attack also represents the tactic’s Achilles’ heel. With Operation Barbarossa (the Nazi invasion of Russia) the Germans tried to apply Blitzkrieg on a front that was so wide that any subsequent attempt to encircle the enemy following penetration proved ineffective, leaving huge gaps for the Russian army to respond.
The Nazis considered Jews to be the main danger to Germany. Jews were the primary victims of Nazi racism, but other victims included Roma (Gypsies) and people with mental or physical disabilities. The Nazis murdered some 200,000 Roma. And they murdered at least 250,000 mentally or physically disabled patients, mainly German and living in institutions, in the so-called Euthanasia Program.
Schindler joined the separatist Sudeten German Party in 1935. Although he was a citizen of Czechoslovakia, Schindler became a spy for the Abwehr, the military intelligence service of Nazi Germany, in 1936. He was assigned to Abwehrstelle II Commando VIII, based in Breslau. He later told Czech police that he did it because he needed the money; by this time Schindler had a drinking problem and was chronically in debt.
