Eichmann received various levels of cooperation from each of the various occupied governments. But in countries such as Holland, Belgium, Albania, Denmark, Finland and Bulgaria, some Jews were saved from their deaths by the action of the sympathetic populace and government officials. Denmark’s government and populace were exemplary in their heroism in saving Jews. In other countries such as Poland, Greece, France, and Yugoslavia, the deportation of Jews to the death camps was facilitated by the cooperation of the government.
In the final months of the war, SS guards moved camp inmates by train or on forced marches, often called “death marches,” in an attempt to prevent the Allied liberation of large numbers of prisoners. As Allied forces moved across Europe in a series of offensives against Germany, they began to encounter and liberate concentration camp prisoners, as well as prisoners en route by forced march from one camp to another. The marches continued until May 7, 1945, the day the German armed forces surrendered unconditionally to the Allies.
Nolte's views were widely denounced. The debate between the "specifists" and "universalists" was acrimonious; the former feared debasement of the Holocaust and the latter considered it immoral to hold the Holocaust as beyond compare. In her book Denying the Holocaust (1993), Deborah Lipstadt viewed Nolte's position as a form of Holocaust denial, or at least "the same triumph of ideology over truth". Addressing Nolte's argument, Eberhard Jäckel wrote in Die Zeit in September 1986 that "never before had a state, with the authority of its leader, decided and announced that a specific group of humans, including the elderly, women, children and infants, would be killed as quickly as possible, then carried out this resolution using every possible means of state power".[h] Despite the criticism of Nolte, Dan Stone wrote in 2010 that the Historikerstreit put "the question of comparison" on the agenda. He argued that the idea of the Holocaust as unique has been overtaken by attempts to place it within the context of early-20th-century Stalinism, ethnic cleansing, and the Nazis' intentions for post-war "demographic reordering", particularly the Generalplan Ost, the plan to kill tens of millions of Slavs to create living space for Germans. The specifist position continued nevertheless to inform the views of many specialists. Richard J. Evans argued in 2015:
Sophia Litwinska made a sworn affidavit that was entered into the British trial of the SS staff at Bergen-Belsen in the fall of 1945. Some members of the SS staff at Belsen had previously worked at Birkenau and they were on trial for crimes committed at both Birkenau and Belsen. One of the men who was tried by the British was Franz Hoessler, the commander of the women's camp at Birkenau in 1942; he was transferred to Bergen-Belsen in December 1944.
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.
