On June 6, 1944, also known as D-Day, more than 150,000 Allied soldiers landed in France. In December the Germans started an unsuccessful counterattack in Belgium and northern France, known as the Battle of the Bulge. Continuing to gain momentum, the Soviets began an offensive in January 1945, liberating western Poland and then forcing Hungary to surrender.
In January 1941, Dachau was designated a Class I camp and Buchenwald became a Class II camp; Mauthausen and Gusen in Austria were the only Class III camps in the Nazi system. The Class I designation meant that treatment of the inmates was less harsh and that prisoners had a better chance of being released. Dachau was the best of the Nazis camps, as far as the treatment of the prisoners was concerned.

Though it had ancient roots, Nazi ideology was far from a primitive, medieval throwback - it was capable of appealing to intelligent and sophisticated people. Many high-ranking Nazis had doctoral degrees and early supporters included such eminent people as philosopher Martin Heidegger, theologian Martin Niemoeller, and commander-in-chief of German forces in the First World War, General Erich Ludendorff. Hitler appealed with a powerful vision of a strong, united and 'racially' pure Germany, bolstered by pseudo-scientific ideas that were popular at the time.
The Jews killed represented around one third of the world population of Jews,[398] and about two-thirds of European Jewry, based on an estimate of 9.7 million Jews in Europe at the start of the war.[399] Much of the uncertainty stems from the lack of a reliable figure for the number of Jews in Europe in 1939, numerous border changes that make avoiding double-counting of victims difficult, lack of accurate records from the perpetrators, and uncertainty about whether deaths occurring months after liberation, but caused by the persecution, should be counted.[392]
There was "practically no resistance" in the ghettos in Poland by the end of 1942, according to Peter Longerich.[305] Raul Hilberg accounted for this by evoking the history of Jewish persecution: as had been the case before, appealing to their oppressors and complying with orders might avoid inflaming the situation until the onslaught abated.[306] Henri Michel argued that resistance consisted not only of physical opposition but of any activity that gave the Jews humanity in inhumane conditions, while Yehuda Bauer defined resistance as actions that in any way opposed the German directives, laws, or conduct.[307] Hilberg cautioned against overstating the extent of Jewish resistance, arguing that turning isolated incidents into resistance elevates the slaughter of innocent people into some kind of battle, diminishes the heroism of those who took active measures to resist, and deflects questions about the survival strategies and leadership of the Jewish community.[308] Timothy Snyder noted that it was only during the three months after the deportations of July–September 1942 that agreement on the need for armed resistance was reached.[309]

When British and Canadian troops finally entered they found over 13,000 unburied bodies and (including the satellite camps) around 60,000 inmates, most acutely sick and starving. The prisoners had been without food or water for days before the Allied arrival, partially due to allied bombing. Immediately before and after liberation, prisoners were dying at around 500 per day, mostly from typhus.[18] The scenes that greeted British troops were described by the BBC's Richard Dimbleby, who accompanied them:
The camp administration did nothing to house the prisoners who were streaming in. Most of them had no roof over their heads, and were without water and food. There was now total chaos in Bergen- Belsen and a typhus epidemic broke out, in the month of March alone 18,168 prisoners perished in the camp and the number of deaths for the period from January to mid-April 1945 was 35,000.
In the aftermath of the Holocaust, many of the survivors found shelter in displaced persons  camps administered by the Allied powers. Between 1948 and 1951, almost 700,000 Jews emigrated to Israel, including 136,000 Jewish displaced persons from Europe. Other Jewish displaced persons emigrated to the United States and other nations. The last camp for Jewish displaced persons closed in 1957.
April 11 - August 14 - Eichmann on trial in Jerusalem for crimes against the Jewish people, crimes against humanity and war crimes. Found guilty and hanged at Ramleh on May 31, 1962. A fellow Nazi reported Eichmann once said "he would leap laughing into the grave because the feeling that he had five million people on his conscience would be for him a source of extraordinary satisfaction."
Dachau, located ten miles north of Munich, Germany, was the first concentration camp built by the Nazis and served as a model for all later camps. By 1937, it held 13,260 prisoners, including German communists and social democrats as well as Jehovah’s Witnesses, Roma (Gypsies), and homosexuals. Dachau also served as the central camp for Christian religious prisoners.
After the joint conquest of Poland, by Germany and the Soviet Union, in September 1939, numerous Polish resistance fighters were imprisoned, including 1,780 Catholic priests. When the Catholic Church complained about the harsh treatment the priests received in the concentration camps, all the priests were moved to Dachau because it was the mildest camp of all. Dachau was designated as the main camp for Catholic priests who had been arrested on various charges, including child molestation, and a total of 2,720 from 19 different nations were sent there. The priests did not have to work in the factories and were given special privileges.
Also in 1936, a new camp called Sachsenhausen was built to replace the former "wild camp" that had been set up in an abandoned brewery in Oranienburg in 1933. The camp in the old brewery was the place where the famous "Arbeit Macht Frei" sign was first erected. When the new Dachau gate house was finished in June 1936, this slogan was put on the iron gate. The words mean "work will set you free." According to Rudolf Hoess, who was on the Dachau staff in 1936, the slogan meant that work sets one free in the spiritual sense, not literally.
The camp of huts near Fallingbostel became known as Stalag XI-B and was to become one of the Wehrmacht's largest POW camps, holding up to 95,000 prisoners from various countries.[6] In June 1940, Belgian and French POWs were housed in the former Bergen-Belsen construction workers' camp. This installation was significantly expanded from June 1941, once Germany prepared to invade the Soviet Union, becoming an independent camp known as Stalag XI-C (311). It was intended to hold up to 20,000 Soviet POWs and was one of three such camps in the area. The others were at Oerbke (Stalag XI-D (321)) and Wietzendorf (Stalag X-D (310)). By the end of March 1942, some 41,000 Soviet POWs had died in these three camps of starvation, exhaustion, and disease. By the end of the war, the total number of dead had increased to 50,000.[6] When the POW camp in Bergen ceased operation in early 1945, as the Wehrmacht handed it over to the SS, the cemetery contained over 19,500 dead Soviet prisoners.
