full_context: Document 1: Rescue of the Danish Jews: The rescue of the Danish Jews occurred during Nazi Germany's occupation of Denmark during World War II. On October 1, 1943, Nazi leader Adolf Hitler ordered Danish Jews to be arrested and deported. Despite great personal risk, the Danish resistance movement, with the assistance of many ordinary Danish citizens, managed to evacuate 7,220 of Denmark's 7,800 Jews, plus 686 non-Jewish spouses, by sea to nearby neutral Sweden.
Document 2: Oskar Schindler: Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist, spy, and 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, which were located 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, and dedication to save the lives of his Jewish employees.
Document 3: Oster Conspiracy: The Oster Conspiracy of 1938 was a proposed plan to overthrow German "Führer" Adolf Hitler and the Nazi regime if Germany went to war with Czechoslovakia over the Sudetenland. It was led by Generalmajor (major general) Hans Oster, deputy head of the "Abwehr" and other high-ranking conservatives within the Wehrmacht who opposed the regime for its behaviour that was threatening to bring Germany into a war that they believed it was not ready to fight. They planned to overthrow Hitler and the Nazi regime through a planned storming of the Reich Chancellery by forces loyal to the plot to take control of the government, who would either arrest or assassinate Hitler, and restore the exiled Wilhelm II as Emperor.
Document 4: Reinhard Heydrich: Reinhard Tristan Eugen Heydrich (] ) (7 March 1904 – 4 June 1942) was a high-ranking German Nazi official during World War II, and a main architect of the Holocaust. He was an SS-"Obergruppenführer und General der Polizei" (Senior Group Leader and General of Police) as well as chief of the Reich Main Security Office (including the Gestapo, Kripo, and SD). He was also "Stellvertretender Reichsprotektor" (Deputy/Acting Reich-Protector) of Bohemia and Moravia. Heydrich served as president of the International Criminal Police Commission (ICPC; later known as Interpol) and chaired the January 1942 Wannsee Conference, which formalised plans for the Final Solution to the Jewish Question—the deportation and genocide of all Jews in German-occupied Europe.
Document 5: Adolf Eichmann: Otto Adolf Eichmann (] ; 19 March 1906 – 1 June 1962) was a German Nazi SS-"Obersturmbannführer" (lieutenant colonel) and one of the major organizers of the Holocaust. Eichmann was tasked by SS-"Obergruppenführer" (general/lieutenant general) Reinhard Heydrich with facilitating and managing the logistics involved in the mass deportation of Jews to ghettos and extermination camps in German-occupied Eastern Europe during World War II. In 1960, Eichmann was captured in Argentina by the Mossad, Israel's intelligence service. Following a widely publicised trial in Israel, he was found guilty of war crimes and hanged in 1962.
Document 6: Georg Ferdinand Duckwitz: Georg Ferdinand Duckwitz (29 September 1904, Bremen – 16 February 1973) was a German diplomat. During World War II he served as an attaché for Nazi Germany in occupied Denmark. He tipped off the Danes about the German's intended deportation of the Jewish population in 1943 and arranged for their reception in Sweden. It is estimated that he prevented the deportation of 95% of Denmark's Jews in the resulting rescue of the Danish Jews.
Document 7: Kurt von Plettenberg: Kurt Freiherr von Plettenberg (31 January 1891 in Bückeburg – 10 March 1945 in Berlin) was a German forester, cavalry officer and a member of the German Resistance (Widerstand). He was involved in the preparations for the 20 July plot, an attempt to assassinate Adolf Hitler, Führer of the Third Reich. Plettenberg belonged to the circle of close friends which included Claus Schenk Graf von Stauffenberg, Johannes Popitz, Ludwig Beck, Ulrich von Hassell, Carl-Hans Graf von Hardenberg and Fabian von Schlabrendorff.
Document 8: Hindu–German Conspiracy: The Hindu–German Conspiracy was a series of plans between 1914 and 1917 by Indian nationalist groups to attempt Pan-Indian rebellion against the British Raj during World War I, formulated between the Indian revolutionary underground and exiled or self-exiled nationalists who formed, in the United States, the Ghadar Party, and in Germany, the Indian independence committee, in the decade preceding the Great War. The conspiracy was drawn up at the beginning of the war, with extensive support from the German Foreign Office, the German consulate in San Francisco, as well as some support from Ottoman Turkey and the Irish republican movement. The most prominent plan attempted to foment unrest and trigger a Pan-Indian mutiny in the British Indian Army from Punjab to Singapore. This plot was planned to be executed in February 1915 with the aim of overthrowing British rule over the Indian subcontinent. The February mutiny was ultimately thwarted when British intelligence infiltrated the Ghadarite movement and arrested key figures. Mutinies in smaller units and garrisons within India were also crushed.
Document 9: Hans Oster: Hans Paul Oster (9 August 1887 – 9 April 1945) was a general in the Wehrmacht of Nazi Germany who was also a leading figure of the German resistance from 1938 to 1943. As deputy head of the counter-espionage bureau in the Abwehr (German military intelligence), Oster was in a strong position to conduct resistance operations under the guise of intelligence work; he was dismissed for helping Jews to avoid arrest.
Document 10: Heinrich Müller (Gestapo): Heinrich Müller (28 April 1900; date of death unknown, but evidence points to May 1945) was a German police official under both the Weimar Republic and Nazi Germany. He became chief of the Gestapo, the political secret state police of Nazi Germany, and was involved in the planning and execution of the Holocaust. He was known as "Gestapo Müller" to distinguish him from another SS general also named Heinrich Müller. He was last seen in the "Führerbunker" in Berlin on 1 May 1945 and remains the most senior figure of the Nazi regime who was never captured or confirmed to have died.
Document 11: Kreisau Circle: The Kreisau Circle (German: "Kreisauer Kreis") (1940–1944) was a group of about twenty-five German dissidents led by Helmuth James Graf von Moltke, who met at his estate in the rural town of Kreisau, Silesia. The circle was composed of men and a few women from a variety of backgrounds, including those of noble descent, devout Protestants and Catholics, professionals, socialists, and conservatives. Despite their differences, the members of the Kreisau Circle found common interest in their opposition to Hitler's Nazi regime on both moral and religious grounds. At their meetings, the circle discussed how they would reorganize the German government after the end of the Third Reich. Although the circle did not promote violent overthrow of the regime, their planning was considered by the Nazis to be treasonous as it rested on the assumption that Germany would lose the war. The group began to falter after Helmuth von Moltke was arrested by the Gestapo in January 1944 and eventually came to an end when most of its members were arrested following Claus von Stauffenberg's attempt on Hitler's life on July 20, 1944.

The operation was carried out in Prague on 27 May 1942 after having been prepared by the British Special Operations Executive with the approval of the Czechoslovak government-in-exile. Wounded in the attack, Heydrich died of his injuries on 4 June 1942. His death led to a wave of merciless reprisals by German SS troops, including the destruction of villages and the killing of civilians. Anthropoid was the only successful assassination of a senior Nazi leader during World War II.
Document 14: Wilm Hosenfeld: Wilhelm Adalbert Hosenfeld (] ; 2 May 1895 – 13 August 1952), originally a school teacher, was a German Army officer who by the end of the Second World War had risen to the rank of "Hauptmann" (Captain). He helped to hide or rescue several Polish people, including Jews, in Nazi-occupied Poland, and helped Polish-Jewish pianist and composer Władysław Szpilman to survive, hidden, in the ruins of Warsaw during the last months of 1944, an act which was portrayed in the 2002 film The Pianist.
