context_page_description: The Holocaust, also known as the Shoah, was the World War II genocide of the European Jews. Between 1941 and 1945, across German-occupied Europe, Nazi Germany and its collaborators systematically murdered some six million Jews, around two-thirds of Europe's Jewish population. The murders were carried out in pogroms and mass shootings; by a policy of extermination through work in concentration camps; and in gas chambers and gas vans in German extermination camps, chiefly Auschwitz, Bełżec, Chełmno, Majdanek, Sobibór, and Treblinka in occupied Poland.
  Germany implemented the persecution in stages. Following Adolf Hitler's appointment as Chancellor on 30 January 1933, the regime built a network of concentration camps in Germany for political opponents and those deemed "undesirable", starting with Dachau on 22 March 1933. After the passing of the Enabling Act on 24 March, which gave Hitler plenary powers, the government began isolating Jews from civil society; this included boycotting Jewish businesses in April 1933 and enacting the Nuremberg Laws in September 1935.
context_section_description: The Polish government-in-exile in London learned about Auschwitz from the Polish leadership in Warsaw, who from late 1940 "received a continual flow of information" about the camp, according to historian Michael Fleming. This was in large measure thanks to Captain Witold Pilecki of the Polish Home Army, who allowed himself to be arrested in September 1940 and sent there. An inmate until he escaped in April 1943, his mission was to set up a resistance movement (ZOW), prepare to take over the camp, and smuggle out information about it.
  On 6 January 1942, the Soviet Minister of Foreign Affairs, Vyacheslav Molotov, sent out diplomatic notes about German atrocities. The notes were based on reports about mass graves and bodies surfacing from pits and quarries in areas the Red Army had liberated, as well as witness reports from German-occupied areas. The following month, Szlama Ber Winer escaped from the Chełmno concentration camp in Poland and passed information about it to the Oneg Shabbat group in the Warsaw Ghetto. His report, known by his pseudonym as the Grojanowski Report, had reached London by June 1942. Also in 1942, Jan Karski sent information to the Allies after being smuggled into the Warsaw Ghetto twice. By late July or early August 1942, Polish leaders in Warsaw had learned about the mass killing of Jews in Auschwitz, according to Fleming. The Polish Interior Ministry prepared a report, Sprawozdanie 6/42, which said at the end:
  There are different methods of execution. People are shot by firing squads, killed by an "air hammer" /Hammerluft/, and poisoned by gas in special gas chambers. Prisoners condemned to death by the Gestapo are murdered by the first two methods. The third method, the gas chamber, is employed for those who are ill or incapable of work and those who have been brought in transports especially for the purpose /Soviet prisoners of war, and, recently Jews/.
  Sprawozdanie 6/42 was sent to Polish officials in London by courier and had reached them by 12 November 1942, where it was translated into English and added to another, "Report on Conditions in Poland", dated 27 November. Fleming writes that the latter was sent to the Polish Embassy in the United States. On 10 December 1942, the Polish Foreign Affairs Minister, Edward Raczyński, addressed the fledgling United Nations on the killings; the address was distributed with the title The Mass Extermination of Jews in German Occupied Poland. He told them about the use of poison gas; about Treblinka, Bełżec and Sobibór; that the Polish underground had referred to them as extermination camps; and that tens of thousands of Jews had been killed in Bełżec in March and April 1942. One in three Jews in Poland were already dead, he estimated, from a population of 3,130,000. Raczyński's address was covered by the New York Times and The Times of London. Winston Churchill received it, and Anthony Eden presented it to the British cabinet. On 17 December 1942, 11 Allies issued the Joint Declaration by Members of the United Nations condemning the "bestial policy of cold-blooded extermination".
  The British and American governments were reluctant to publicize the intelligence they had received. A BBC Hungarian Service memo, written by Carlile Macartney, a BBC broadcaster and senior Foreign Office adviser on Hungary, stated in 1942: "We shouldn't mention the Jews at all." The British government's view was that the Hungarian people's antisemitism would make them distrust the Allies if their broadcasts focused on the Jews. The US government similarly feared turning the war into one about the Jews; antisemitism and isolationism were common in the US before its entry into the war. Although governments and the German public appear to have understood what was happening, it seems the Jews themselves did not. According to Saul Friedländer, "[t]estimonies left by Jews from all over occupied Europe indicate that, in contradistinction to vast segments of surrounding society, the victims did not understand what was ultimately in store for them." In Western Europe, he writes, Jewish
