The 15 men present at Wannsee included Adolf Eichmann (head of Jewish affairs for the RSHA and the man who organized the deportation of Jews), Heinrich Müller (head of the Gestapo), and other party leaders and department heads.[256] Thirty copies of the minutes were made. Copy no. 16 was found by American prosecutors in March 1947 in a German Foreign Office folder.[263] Written by Eichmann and stamped "Top Secret", the minutes were written in "euphemistic language" on Heydrich's instructions, according to Eichmann's later testimony.[264] The conference had several purposes. Discussing plans for a "final solution to the Jewish question" ("Endlösung der Judenfrage"), and a "final solution to the Jewish question in Europe" ("Endlösung der europäischen Judenfrage"),[256] it was intended to share information and responsibility, coordinate efforts and policies ("Parallelisierung der Linienführung"), and ensure that authority rested with Heydrich. There was also discussion about whether to include the German Mischlinge (half-Jews).[265] Heydrich told the meeting: "Another possible solution of the problem has now taken the place of emigration, i.e. the evacuation of the Jews to the East, provided that the Fuehrer gives the appropriate approval in advance."[256] He continued:
After the arrival of a transport at the ramp in Birkenau, the process known as selection took place. SS officers decided who would be taken to work, and who would be sent directly to the gas chambers. Often it was mere chance or the mood of the SS officer that decided whether someone died immediately or had a hope of survival. The prisoners selected for slave labour were sent to one of the many auxiliary camps at Auschwitz or elsewhere in the Nazi concentration camp system. Their aim was „Vernichtung durch Arbeit“ - extermination through labour.

Auschwitz-Birkenau was also a killing center and played a central role in the German effort to kill the Jews of Europe. Around the beginning of September, 1941, the SS at Auschwitz I conducted the first tests of Zyklon B as a mass murder agent, using Soviet POWs and debilitated Polish prisoners as victims. The “success” of these experiments led to the construction of a chamber in the crematorium of Auschwitz I that, like the subsequent gas chambers at Auschwitz, used Zyklon B to murder victims. The first transports of Jewish men, women, and children sent to Auschwitz as part of the “final solution” were murdered in this gas chamber (Crematorium I) in February and March 1942.

When he learned what had happened, Schindler at first managed to secure the release of the men from the Gross-Rosen camp.  He then proceeded to send his personal German secretary to Auschwitz to negotiate the release of the women. The latter managed to obtain the release of the Jewish women by promising to pay 7 RM daily per worker. This is the only recorded case in the history of the extermination camp that such a large group of people were allowed to leave alive while the gas chambers were still in operation.

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.
Oskar Schindler, (born April 28, 1908, Svitavy [Zwittau], Moravia, Austria-Hungary [now in the Czech Republic]—died October 9, 1974, Hildesheim, West Germany), German industrialist who, aided by his wife and staff, sheltered approximately 1,100 Jews from the Nazis by employing them in his factories, which supplied the German army during World War II.
Once Germany took over Poland in 1939, it created forced-labor camps. Thousands of prisoners died from working conditions, exhaustion, and starvation. After the outbreak of World War II, the number of concentration camps increased exponentially. The number of prisoners of war camps also rose, but after the first years of the war most were converted into concentration camps. Nazis forcibly relocated Jews from ghettos to concentration camps.
These gassing facilities soon proved inadequate for the task of murdering the large numbers of Jewish deportees being sent to Auschwitz. Between March and June 1943, four large crematoria were built within Auschwitz-Birkenau, each with a gas chamber, a disrobing area, and crematory ovens. Gassings ceased at Bunkers I and II when Crematoria II through V began operating, although Bunker II was put back into operation during the deportation of Hungary’s Jews in 1944. Gassing of newly arrived transports ceased at Auschwitz by early November 1944.
In order to protect the tanks, and secure the areas penetrated by the German army, motorized infantry would accompany tanks into battle. The Germans believed the only way to defeat an enemy force was to cut it off. Cutting it off required superior mobility relative to the enemy force. The introduction of mechanical means on the battlefield provided the Germans the answer to the deadlocks common in WWI. Tanks and other armored vehicles gave the German Army the ability to force the enemy to react to their new found mobility.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
