The first major camp to be encountered by Allied troops, Majdanek, was discovered by the advancing Soviets on 25 July 1944.[375] Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Germans in 1943.[376] Auschwitz was liberated, also by the Soviets, on 27 January 1945;[377] Buchenwald by the Americans on 11 April;[378] Bergen-Belsen by the British on 15 April;[379] Dachau by the Americans on 29 April;[380] Ravensbrück by the Soviets on 30 April;[381] and Mauthausen by the Americans on 5 May.[382] The Red Cross took control of Theresienstadt on 4 May, days before the Soviets arrived.[383][384]
Advocacy organizations worldwide called for British Royal Air Forces to bomb concentration camps particularly at Auschwitz. Although the plan was adopted by British Prime Minister Winston Churchill poor information-sharing between parts of the British government led the order to be ignored and the plan dropped. Such calculations were hardly the low point of Allied Responses. One story has that, low on supplies, the Nazis offered the British a million Jews in exchange for 10,000 trucks, which one British diplomat promptly refused saying, “What would I do with one million Jews? Where would I put them?”

Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]

“Who has made us Jews different from all other people? Who has allowed us to suffer so terribly up until now? It is God who has made us as we are, but it will be God, too, who will raise us up again. Who knows? It might even be our religion from which the world and all peoples learn good, and for that reason and only that reason do we suffer. We can never become just Netherlanders, or just English or representatives of any country for that matter. We will always remain Jews, but we want to, too.” – April 11, 1944
But they were gradually shut out of German society by the Nazis through a never-ending series of laws and decrees, culminating in the Nuremberg Laws of 1935 which deprived them of their German citizenship and forbade intermarriage with non-Jews. They were removed from schools, banned from the professions, excluded from military service, and were even forbidden to share a park bench with a non-Jew.
On January 30, 1933, Adolf Hitler, leader of the National Socialist German Workers (Nazi) Party, was named chancellor of Germany by President Paul von Hindenburg after the Nazi party won a significant percentage of the vote in the elections of 1932. The Nazi Party had taken advantage of the political unrest in Germany to gain an electoral foothold. The Nazis incited clashes with the communists and conducted a vicious propaganda campaign against its political opponents - the weak Weimar government and the Jews whom the Nazis blamed for Germany's ills.
The first killing center set up in occupied Polish lands was the camp at Chełmno on the Ner; Jews brought in from the ghettos in the Wartheland were being killed there from December 1941. Three more camps, somewhat larger, were opened at Bełżec, Sobibor, and Treblinka (in what was known as “Aktion Reinhard”) somewhat later, between March and July 1942.
The capture, trial and execution in the early 1960s of Adolf Eichmann, the bureaucratic organizer of the Holocaust, led many people to believe that the Mossad would next want to get its hands on Mengele. Many in Israel and around the world figured that the Mossad would have no trouble doing so. But the truth was that for years, the leaders of the government and the agency were simply not all that interested.
At the same time, the Germans set about liquidating the ghettos in occupied Poland. July 22, 1942, when the deportation of Jews from Warsaw to the death camp in Treblinka began, is regarded as a symbolic date. A decided majority of the Polish Jews were killed in a little over half a year, after which the SS began liquidating the Aktion Reinhard camps. However, the last great death camp—Auschwitz—remained in existence until the beginning of 1945. It was mainly Jews from Western and Southern Europe, from the liquidated labor camps, and the ghettos in Sosnowiec and Łódź, who died in the gas chambers there.

In the decades that followed the Nuremburg Trials, in which Nazi officials, charged with crimes against peace and humanity, hid behind the excuse that they were just following orders, historians grappled with questions of blame and guilt. Had Hitler and top Nazi officials been solely responsible for the genocide? How complicit were lower-level Nazis and members of the Order Police?
While these massacres were happening, the Nazis elsewhere were laying plans for an overall 'solution to the Jewish question'. Death camp operations began in December 1941 at Semlin in Serbia and Chelmno in Poland, where people were killed by exhaust fumes in specially modified vans, which were then driven to nearby sites where the bodies were plundered and burnt. 250,000 Jews were killed this way at Chelmno and 15,000 at Semlin.

Meanwhile, Hitler continued his conquest of Europe, invading Belgium, Holland, Luxembourg and France, placing ever-increasing numbers of Jews under Nazi control. The Nazis then began carefully tallying up the actual figures and also required Jews to register all of their assets. But the overall question remained as to what to do with the millions of Jews now under Nazi control - referred to by the Nazis themselves as the Judenfrage (Jewish question).
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]
Shown in the 1944 photo above, from left to right, are Dr. Josef Mengele, Richard Baer, Karl Hoecker, and Walter Schmidetski. Richard Baer, known as the last Commandant of Auschwitz, was the commander of the main camp; his adjutant was Karl Hoecker. Dr. Josef Mengele was one of 30 SS officers at Auschwitz II, aka Birkenau, who decided who would live and who would die in the gas chambers.
The passengers had landing certificates and transit visas by the Cuban Director-General of Immigration, Manuel Benitez Gonzalez. But, a week before the ship left, Cuban President Federico Laredo Bru published a decree that overturned all recent landing certificates. For them to land in Cuba, they needed written authorization from the Cuban Secretaries of State and Labor and a $500 bond. Most of the passengers were not prepared for the bureaucratic mess they were about to face in Cuba.
From the earliest years of the Nazi regime, German authorities persecuted homosexuals and others whose behavior did not match prescribed social norms. German police officials targeted thousands of political opponents (including Communists, Socialists, and trade unionists) and religious dissidents (such as Jehovah's Witnesses). Many of these individuals died as a result of incarceration and maltreatment.
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.
When the Nazis occupied western Poland in 1939, two-thirds of Polish Jews - Europe's largest Jewish community - fell into their hands. The Polish Jews were rounded up and placed in ghettos, where it is estimated that 500,000 people died of starvation and disease. Nazi policy at this point was aimed at forced emigration and isolation of the Jews rather than mass murder, but large numbers were to die through attrition.
The Germans invaded the Netherlands, Luxembourg, Belgium, and France in May 1940. In the Netherlands, the Germans installed Arthur Seyss-Inquart as Reichskommissar, who quickly began to persecute the approximately 140,000 Dutch Jews. Jews were forced out of their jobs and had to register with the government. Non-Jewish Dutch citizens protested these measures, and in February 1941 they staged a strike that was quickly crushed.[161] After Belgium's surrender at the end of May 1940, it was ruled by a German military governor, Alexander von Falkenhausen, who enacted anti-Jewish measures against the country's 90,000 Jews, many of whom were refugees from Germany or Eastern Europe.[162]
The match was perfect. The video image of the photograph was imposed precisely over the video image of the skull. It was a face wrapped over a skull, subject over object, an image of life over an image of death. While the images helped to push the probability calculation further in the direction of a definitive identification, they did more than that, for it was the appearance of a previously unseen image that produced the potential for conviction.
But Soviet forces were hurtling toward Auschwitz, and in November the order went out to conceal all evidences of gassing and to blow up the crematoria. Tens of thousands of inmates, debilitated and already near extinction, were driven out in bitter cold on death marches. Many were shot. In an evacuation that occurred either on October 28th or on November 2nd, Anne and Margot were dispatched to Bergen-Belsen. Margot was the first to succumb. A survivor recalled that she fell dead to the ground from the wooden slab on which she lay, eaten by lice, and that Anne, heartbroken and skeletal, naked under a bit of rag, died a day or two later.
Throughout German-occupied territory the situation of the Jews was desperate. They had meagre resources and few allies and faced impossible choices. A few people came to their rescue, often at the risk of their own lives. Swedish diplomat Raoul Wallenberg arrived in Budapest on July 9, 1944, in an effort to save Hungary’s sole remaining Jewish community. Over the next six months, he worked with other neutral diplomats, the Vatican, and Jews themselves to prevent the deportation of these last Jews. Elsewhere, Le Chambon-sur-Lignon, a French Huguenot village, became a haven for 5,000 Jews. In German-occupied Poland, where it was illegal to aid Jews and where such action was punishable by death, the Zegota (Council for Aid to Jews) rescued a similar number of Jewish men, women, and children. Financed by the London-based Polish government in exile and involving a wide range of clandestine political organizations, Zegota provided hiding places and financial support and forged identity documents.

Beginning with the British air raids on Cologne in May of 1942, the Allies launched a strategic bombing campaign that would target cities and industrial plants across the Reich for the next three years. In the summer of 1942, Germany and its allies focused on the Soviet Union unsuccessfully. The Soviet Union gained the dominant role, which it would maintain for the rest of the war.
The economic strains of the Great Depression led some in the German medical establishment to advocate murder (euphemistically called "euthanasia") of the "incurable" mentally and physically disabled as a cost-saving measure to free up funds for the curable.[66] By the time the National Socialist German Workers' Party, or Nazi Party,[j] came to power in 1933, there was already a tendency to seek to save the racially "valuable", while ridding society of the racially "undesirable".[68] The party had originated in 1920[67] as an offshoot of the völkisch movement, and it adopted that movement's antisemitism.[69] Early antisemites in the party included Dietrich Eckart, publisher of the Völkischer Beobachter, the party's newspaper, and Alfred Rosenberg, who wrote antisemitic articles for it in the 1920s. Rosenberg's vision of a secretive Jewish conspiracy ruling the world would influence Hitler's views of Jews by making them the driving force behind communism.[70] The origin and first expression of Hitler's antisemitism remain a matter of debate.[71] Central to his world view was the idea of expansion and lebensraum (living space) for Germany. Open about his hatred of Jews, he subscribed to the common antisemitic stereotypes.[72] From the early 1920s onwards, he compared the Jews to germs and said they should be dealt with in the same way. He viewed Marxism as a Jewish doctrine, said he was fighting against "Jewish Marxism", and believed that Jews had created communism as part of a conspiracy to destroy Germany.[73]
Jews were forced to move, often to different cities or countries, and live in designated areas, referred to as ghettos. Most of the ghettos were “open” which meant Jews were free to come and go during the daytime. As time past, more and more ghettos became “closed” meaning that Jews were trapped and not allowed to leave. No ghettos were ever established within the borders of Germany and most were only meant as a temporary means of isolating Jews from the German population until they could be moved elsewhere.
“There is no stopping them [the Jews]. Are there no clear signs that the twilight of the Jews is setting in? No. Jewry’s control of society and politics as well as its domination of religious and ecclesiastical thought is still in the prime of its development. Yes, through the Jewish nation Germany will become a world power, a western new Palestine. And this will happen not through violent revolution but through the compliance of the people. We should not reproach the Jewish nation. It fought against the western world for 1,800 years and finally conquered it. We were vanquished. The Jews were late in their assault on Germany but once started there was no stopping them
Mengele was born on 16 March 1911 to Walburga (née Hupfauer) and Karl Mengele in Günzburg, Bavaria, Germany.[4] He was the oldest of three children; his two younger brothers were Karl Jr. and Alois. Their father was founder of the Karl Mengele & Sons company, producers of farm machinery.[5] Josef was successful at school and developed an interest in music, art, and skiing.[6] He completed high school in April 1930 and went on to study philosophy in Munich,[7] where the headquarters of the Nazi Party were located.[8] In 1931, Mengele joined the Stahlhelm, Bund der Frontsoldaten, a paramilitary organization that was absorbed into the Nazi Sturmabteilung (Storm Detachment; SA) in 1934.[7][9]
