Entering conquered Soviet territories alongside the Wehrmacht (the German armed forces) were 3,000 men of the Einsatzgruppen (“Deployment Groups”), special mobile killing units. Their task was to murder Jews, Soviet commissars, and Roma in the areas conquered by the army. Alone or with the help of local police, native anti-Semitic populations, and accompanying Axis troops, the Einsatzgruppen would enter a town, round up their victims, herd them to the outskirts of the town, and shoot them. They killed Jews in family units. Just outside Kiev, Ukraine, in the ravine of Babi Yar, an Einsatzgruppe killed 33,771 Jews on September 28–29, 1941. In the Rumbula Forest outside the ghetto in Riga, Latvia, 25,000–28,000 Jews were shot on November 30 and December 8–9. Beginning in the summer of 1941, Einsatzgruppen murdered more than 70,000 Jews at Ponary, outside Vilna (now Vilnius) in Lithuania. They slaughtered 9,000 Jews, half of them children, at the Ninth Fort, adjacent to Kovno (now Kaunas), Lithuania, on October 28.
In the fall of that year the Płaszów work camp opened nearby, and by February 1943 it was under the command of the notoriously sadistic SS officer Amon Göth, who would be executed after the war. Capitalizing on the officer’s appetite for drink and other luxury items available mainly on the black market, Schindler cultivated his friendship by ensuring a constant stream of them to the villa from which he oversaw the camp. Schindler thus managed to prevail upon Göth to create a separate camp for his Jewish workers, where they were free of the abuses suffered at Płaszów. Though Schindler’s motivations prior to this point are unclear, many scholars interpret his efforts to extricate his workers from Płaszów as indication that his concern for them was not purely financial.
The 40-year-old Eicke was a veteran of World War I who had earned the Iron Cross 2nd Class. After the war he became involved in police work but had lost various jobs because of his strong opposition to Germany's democratic republic. He joined the Nazi Party in December 1928 and was then taken into the SS. Himmler appointed him as a full SS colonel in November 1931. Four months later, he fled to Italy on Himmler's orders after being sentenced to jail for participating in Nazi political bombings. Himmler brought him back to Germany in February 1933. But more trouble occurred after Eicke clashed with a local Gauleiter who had him hauled off to a psychiatric clinic as a "dangerous lunatic." Himmler had him released from the psychiatric lock-up on June 26, then immediately handed him the task of running Dachau.
Bergen-Belsen [ˈbɛʁɡn̩.bɛlsn̩], or Belsen, was a Nazi concentration camp in what is today Lower Saxony in northern Germany, southwest of the town of Bergen near Celle. Originally established as a prisoner of war camp, in 1943, parts of it became a concentration camp. Initially this was an "exchange camp", where Jewish hostages were held with the intention of exchanging them for German prisoners of war held overseas. The camp was later expanded to accommodate Jews from other concentration camps.
