Victims usually arrived at the camps by freight train.[278] Almost all arrivals at the Operation Reinhard camps of Treblinka, Sobibór, and Bełżec were sent directly to the gas chambers,[279] with individuals occasionally selected to replace dead workers.[280] At Auschwitz, camp officials usually subjected individuals to selections;[281] about 25%[282] of the new arrivals were selected to work.[281] Those selected for death at all camps were told to undress and hand their valuables to camp workers.[283] They were then herded naked into the gas chambers. To prevent panic, they were told the gas chambers were showers or delousing chambers.[284] The procedure at Chełmno was slightly different. Victims there were placed in a mobile gas van and asphyxiated, while being driven to prepared burial pits in the nearby forests. There the corpses were unloaded and buried.[285]
These three extermination factories — with Belzec responsible for about 600,000 victims, Sobibor 200,000, Treblinka 900,000 — shared certain features. Like Auschwitz at a later stage, they were equipped with railroad terminals that the trains entered in reverse. The victims were ordered to undress and then led through a corridor to the gas chambers; the gas was composed of carbon monoxide produced by diesel motors. At first, the corpses were buried in mass graves, later they were burnt in crematoria. The similarity to the “euthanasia” program was evident here too. In August 1941, the camps inspector was SS Sturmbannfiihrer Christian Wirth who, like dozens of other specialists of “Operation T4,” was placed under Odilo Globocnik, the commander of the SS for the region of Lublin.
Not long after beginning the survey of the site, Freund and his team confirmed the existence of a previously unmarked burial pit. At 80 feet across and 15 feet deep, the scientists calculated that the grave contained the cremated remains of as many as 7,000 people. The researchers also released the preliminary results of their search for the tunnel, along with a series of ERT-generated cross sections that revealed the tunnel’s depth beneath the ground’s surface (15 feet at points) and its dimensions: three feet by three feet at the very widest, not much larger than a human torso. From the entrance inside the bunker to the spot in the forest, now long grown over, where the prisoners emerged measured more than 110 feet. At last, there was definitive proof of a story known until now only in obscure testimonies made by a handful of survivors—a kind of scientific witness that transformed “history into reality,” in the words of Miri Regev, Israel’s minister of culture, who highlighted the importance of documenting physical evidence of Nazi atrocities as a bulwark against “the lies of the Holocaust deniers.”
In order to make way for these new prisoners, the SS took many thousands of Jews from the ghettos of Kovno, Riga, Minsk, Łódź, Lvov and Lublin to be murdered by the Einsatzgruppen. Even though the SS claimed to be the hardened ‘Master Race’, quite a few of them found it ‘difficult’ to murder women and children. In addition, the shooting process used by the Einsatzgruppen was expensive.
“With respect of the Jewish Question, the Führer has decided to make a clean sweep. He prophesied to the Jews that if they again brought about a world war, they would live to see their annihilation in it. That wasn’t just a catchword… If the German people have now again sacrificed 160,000 dead on the eastern front, then those responsible for this bloody conflict will have to pay with their lives.”
After Kristallnacht, Jewish businesses were expropriated, private employers were urged to sack Jewish employees, and offices were set up to speed emigration. Imprisoned Jews could buy freedom if they promised to leave the country, abandoning their assets. By the outbreak of war in September 1939, half of Germany's 500,000 Jews had fled, as had many Jews from Austria and the German-occupied parts of Czechoslovakia.
But this week the Israeli courts waded into the process of selecting who to include on the list of righteous gentiles at the Yad Vashem Holocaust memorial in Jerusalem amid a campaign to add two Germans - one of them a convicted war criminal who was at the centre of a recent Hollywood film - and to strike off a Ukrainian who Jewish survivors say has no place among heroes.
After its defeat in World War I, Germany was humiliated by the Versailles Treaty, which reduced its prewar territory, drastically reduced its armed forces, demanded the recognition of its guilt for the war, and stipulated it pay reparations to the allied powers. With the German Empire destroyed, a new parliamentary government called the Weimar Republic was formed. The republic suffered from economic instability, which grew worse during the worldwide depression after the New York stock market crash in 1929. Massive inflation followed by very high unemployment heightened existing class and political differences and began to undermine the government.
Sprawozdanie 6/42 was sent to Polish officials in London by courier and had reached them by 12 November 1942, when it was translated into English and added to another report, "Report on Conditions in Poland". Dated 27 November, this was forwarded to the Polish Embassy in the United States.[341] 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 Sobibor; 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.[342] One in three Jews in Poland were already dead, he estimated, from a population of 3,130,000.[343] 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".[344][345]
Holocaust, Hebrew Shoʾah (“Catastrophe”), Yiddish and Hebrew Ḥurban (“Destruction”), the systematic state-sponsored killing of six million Jewish men, women, and children and millions of others by Nazi Germany and its collaborators during World War II. The Germans called this “the final solution to the Jewish question.” Yiddish-speaking Jews and survivors in the years immediately following their liberation called the murder of the Jews the Ḥurban, the word used to describe the destruction of the First Temple in Jerusalem by the Babylonians in 586 bce and the destruction of the Second Temple by the Romans in 70 ce. Shoʾah (“Catastrophe”) is the term preferred by Israelis and the French, most especially after Claude Lanzmann’s masterful 1985 motion picture documentary of that title. It is also preferred by people who speak Hebrew and by those who want to be more particular about the Jewish experience or who are uncomfortable with the religious connotations of the word Holocaust. Less universal and more particular, Shoʾah emphasizes the annihilation of the Jews, not the totality of Nazi victims. More particular terms also were used by Raul Hilberg, who called his pioneering work The Destruction of the European Jews, and Lucy S. Dawidowicz, who entitled her book on the Holocaust The War Against the Jews. In part she showed how Germany fought two wars simultaneously: World War II and the racial war against the Jews. The Allies fought only the World War. The word Holocaust is derived from the Greek holokauston, a translation of the Hebrew word ʿolah, meaning a burnt sacrifice offered whole to God. This word was chosen because in the ultimate manifestation of the Nazi killing program—the extermination camps—the bodies of the victims were consumed whole in crematoria and open fires.

Once the Nazis took over Budapest in 1944 and began deporting Jews to the death camps, Lutz negotiated a special deal with the Hungarian government and the Nazis: he had permission to issue protective letters to 8,000 Hungarian Jews for emigration to Palestine. Lutz then deliberately misinterpreted his permission for 8,000 as applying to families rather than individuals, and proceeded to issue tens of thousands of additional protective letters, all of them bearing a number between one and 8,000. He also set up some 76 safe houses around Budapest, declaring them annexes of the Swiss legation. Among the safe houses was the now well-known "Glass House" (Üvegház) at Vadász Street 29. About 3,000 Jews found refuge at the Glass House and in a neighboring building.
The mass killings of Jews in the occupied Soviet territories were assigned to four SS formations called Einsatzgruppen ("task groups"), which were under Heydrich's overall command. Similar formations had been used to a limited extent in Poland in 1939, but the ones operating in the Soviet territories were much larger.[242] The Einsatzgruppen's commanders were ordinary citizens: the great majority were professionals and most were intellectuals.[243] By the winter of 1941–1942, the four Einsatzgruppen and their helpers had killed almost 500,000 people.[244] The largest massacre of Jews by the mobile killing squads in the Soviet Union was at a ravine called Babi Yar outside Kiev,[245] where 33,771 Jews were killed in a single operation on 29–30 September 1941.[246][n] A mixture of SS and Security Police, assisted by Ukrainian police, carried out the killings.[248] Although they did not actively participate in the killings, men of the German 6th Army helped round up the Jews of Kiev and transport them to be shot.[249] By the end of the war, around two million are thought to have been victims of the Einsatzgruppen and their helpers in the local population and the German Army. Of those, about 1.3 million were Jews and up to a quarter of a million Roma.[250]
For Begin, getting to Mengele was not just a matter of the past. He equated Yasir Arafat with Hitler. “Unlike other Israelis, who saw the Holocaust as a one-time historical catastrophe,” said Shlomo Nakdimon, a prominent Israeli journalist who was close to Begin, “Begin believed with all his heart that the lesson of the Holocaust is that the Jewish people must protect themselves in their own country in order to prevent a renewed threat to their existence.”
Mengele's name was mentioned several times during the Nuremberg trials in the mid-1940s, but the Allied forces believed that he was probably already dead.[79] Irene Mengele and the family in Günzburg also alleged that he had died.[80] Working in West Germany, Nazi hunters Simon Wiesenthal and Hermann Langbein collected information from witnesses about Mengele's wartime activities. In a search of the public records, Langbein discovered Mengele's divorce papers, which listed an address in Buenos Aires. He and Wiesenthal pressured the West German authorities into starting extradition proceedings, and an arrest warrant was drawn up on 5 June 1959.[81][82] Argentina initially refused the extradition request because the fugitive was no longer living at the address given on the documents; by the time extradition was approved on 30 June, Mengele had already fled to Paraguay and was living on a farm near the Argentine border.[83]
Soon after, a Mossad surveillance team saw a man matching Mengele’s description enter a pharmacy owned by a person who was known to be in touch with him. On July 23, 1962, the Mossad operative Zvi Aharoni (who had identified Eichmann two years earlier) was on a dirt road by the farm where Mengele was believed to be hiding when he encountered a group of men — including one who looked exactly like the fugitive.

Construction work on the first killing centre at Bełżec in occupied Poland began in October 1941, three months before the Wannsee Conference. The new facility was operational by March the following year.[75] By mid-1942, two more death camps had been built on Polish lands: Sobibór operational by May 1942, and Treblinka operational in July.[76] From July 1942, the mass murder of Polish and foreign Jews took place at Treblinka as part of Operation Reinhard, the deadliest phase of the Final Solution. More Jews were killed at Treblinka than at any other Nazi extermination camp apart from Auschwitz.[77] By the time the mass killings of Operation Reinhard ended in 1943, roughly two million Jews in German-occupied Poland had been murdered.[66] The total number of people killed in 1942 in Lublin/Majdanek, Bełżec, Sobibór, and Treblinka was 1,274,166 by Germany's own estimation, not counting Auschwitz II Birkenau nor Kulmhof.[78] Their bodies were buried in mass graves initially.[79] Both Treblinka and Bełżec were equipped with powerful crawler excavators from Polish construction sites in the vicinity, capable of most digging tasks without disrupting surfaces.[80] Although other methods of extermination, such as the cyanic poison Zyklon B, were already being used at other Nazi killing centres such as Auschwitz, the Aktion Reinhard camps used lethal exhaust gases from captured tank engines.[81]
Mengele's work also involved carrying out selections, a task that he chose to perform even when he was not assigned to do so, in the hope of finding subjects for his experiments,[33] with a particular interest in locating sets of twins.[34] In contrast to most of the other SS doctors, who viewed selections as one of their most stressful and unpleasant duties, he undertook the task with a flamboyant air, often smiling or whistling a tune.[35][31] He was also one of the SS doctors responsible for supervising the administration of Zyklon B, the cyanide-based pesticide that was used for the mass killings in the Birkenau gas chambers. He served in this capacity at the gas chambers located in crematoria IV and V.[36]
