One of the most remarkable humanitarian acts performed by Oskar and Emilie Schindler involved the case of 120 Jewish male prisoners from Goleszow, a sub-camp of Auschwitz. The men had been working there in a quarry plant that belonged to the SS-operated company “German Earth and Stone Works.”  With the approach of the Russian front in January 1945, they were evacuated from Goleszow and transported westward in sealed cattle-wagons, without food or water. At the end of a seven-day grueling journey in the dead of winter, the SS guards finally stationed the two sealed cattle-cars with their human cargo at the gates of Brunnlitz. Emilie Schindler was just in time to stop the SS camp commandant from sending the train back. Schindler, who had rushed back to the camp from some food-procuring errand outside, barely managed to convince the commandant that he desperately needed the people who were locked in the train for work.
Some prisoners—usually Aryan—were assigned positions of authority, such as Blockschreiber ("block clerk"), Funktionshäftling ("functionary"), Kapo ("head" or "overseer"), and Stubendienst ("barracks orderly"). They were considered members of the camp elite, and had better food and lodgings than the other prisoners. The Kapos in particular wielded tremendous power over other prisoners, whom they often abused.[88][89] Very few Kapos were prosecuted after the war, because of the difficulty in determining which Kapo atrocities had been performed under SS orders and which had been individual actions.[90]
Methods of mass murder evolved at local levels as well as being decreed from Nazi high command. Killing squads rounded up and shot entire Jewish communities. Over two days in Kiev, 33,771 Jews were shot. The murder of Jews rapidly escalated, in part because local Nazi leaders didn’t have enough room to place them in the ghettos. By the end of the year, plans to implement the systematic slaughter of Jews by using gas in mobile trucks and gas chambers were well underway.

German volunteers first used armour in live field conditions during the Spanish Civil War of 1936. Armour commitment consisted of Panzer Battalion 88, a force built around three companies of Panzer I tanks that functioned as a training cadre for Nationalists. The Luftwaffe deployed squadrons of fighters, dive bombers and transport aircraft as the Condor Legion.[77] Guderian said that the tank deployment was "on too small a scale to allow accurate assessments to be made."[78] The true test of his "armoured idea" would have to wait for the Second World War. However, the Luftwaffe also provided volunteers to Spain to test both tactics and aircraft in combat, including the first combat use of the Stuka.[79]
Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]
What the arms, whose charges can be partly traced in tithing seals and boundary stones back to the 16th century, mean is unclear. The charge that the German blazon describes as a “wall anchor” (Maueranker) is not accepted as such by everyone, with some saying it could have been meant to be taken as a weaver’s reel. With a document from 22 July 1926, the interior minister of the People's State of Hesse granted the community the right to bear these arms.
Yugoslavia and Greece were invaded in April 1941 and surrendered before the end of the month. Germany and Italy divided Greece into occupation zones but did not eliminate it as a country. Yugoslavia, home to around 80,000 Jews, was dismembered; regions in the north were annexed by Germany and regions along the coast made part of Italy. The rest of the country was divided into the Independent State of Croatia, nominally an ally of Germany, and Serbia, which was governed by a combination of military and police administrators.[167] According to historian Jeremy Black, Serbia was declared free of Jews in August 1942.[168] Croatia's ruling party, the Ustashe, killed the country's Jews, and killed or expelled Orthodox Christian Serbs and Muslims.[167] Jews and Serbs alike were "hacked to death and burned in barns", according to Black. One difference between the Germans and Croatians was that the Ustashe allowed its Jewish and Serbian victims to convert to Catholicism so they could escape death.[168]
^ The escapees included 396 Polish men and 10 Polish women; 164 men from the Soviet Union (including 50 prisoners of war), and 15 women; 112 Jewish men and three Jewish women; 36 Romani/Sinti men and two women; 22 German men and nine women; 19 Czech men and four women; two Austrians; one Yugoslav woman and one man; and 15 other men and one woman.[216]
The Blitzkrieg was fundamentally about moving away from the tried and tested methods of modern warfare and creating a new, more effective doctrine. To that end, Hitler had given his full backing to Guderian. Ironically, he had got his idea for Blitzkrieg from two officers – one from France and one from Britain and he had copied and broadened what they had put on paper. In Britain and France, however, the cavalry regiments ruled supreme and they were adamant that the tanks would not get any influence in their armies. The High Commands of both countries were dominated by the old traditional cavalry regiments and their political pull was great. These were the type of officers despised by Hitler and he took to his Panzer officer, Guderian, over the old officers that were in the German Army (the Wehrmacht). 
In nearly every country overrun by the Nazis, the Jews were forced to wear badges marking them as Jews, they were rounded up into ghettos or concentration camps and then gradually transported to the killing centers. The death camps were essentially factories for murdering Jews. The Germans shipped thousands of Jews to them each day. Within a few hours of their arrival, the Jews had been stripped of their possessions and valuables, gassed to death, and their bodies burned in specially designed crematoriums. Approximately 3.5 million Jews were murdered in these death camps.
In 1944, Josiah DuBois, Jr. wrote a memorandum to then-Secretary of the Treasury Henry Morgenthau, Jr. entitled “Report to the Secretary on the Acquiescence of This Government in the Murder of the Jews”, which condemned the bureaucratic interference of U.S. State Department policies in obstructing the evacuation of Holocaust Refugees from Romania and Occupied France. The Report would spur the Roosevelt administration to create the War Refugee Board later that year.
Schindler first arrived in Kraków in October 1939, on Abwehr business, and took an apartment the following month. Emilie maintained the apartment in Ostrava and visited Oskar in Kraków at least once a week.[18][19] In November 1939, he contacted interior decorator Mila Pfefferberg to decorate his new apartment. Her son, Leopold "Poldek" Pfefferberg, soon became one of his contacts for black market trading. They eventually became lifelong friends.[20]
