Browning also notes that the destruction of the Jews went hand-in-hand with a much wider attempt at “ethnic cleansing” throughout Eastern Europe. The Nazis had well-advanced plans, which might have been realized had they won the war, to remove by force millions of Poles and other Slavs to Siberia, with vast numbers certain to die en route. One of the major merits of Browning’s book is its detailed discussion of these plans, as well as Nazi policies towards the gypsies. Browning notes, correctly, that the Nazis killed large numbers of gypsies even though Hitler hardly ever mentioned them and certainly did not have anti-gypsy hostility at the heart of his ideology. Browning also offers a detailed consideration of the Nazi program of murdering the physically and mentally handicapped among “Aryan” Germans (the “T4 program”), which began in mid-1939 and eventually claimed seventy thousand victims before it was stopped in mid-1941, and he reports that many of the killers in the T4 program went on to be directly involved with the extermination of the Jews in Eastern Europe.
Same edition as the one I have read from my local library. This appears to be as fine an edition as you can get, and I have done a fair amount of research on that. This, the "definitive edition" has a lot of material that did not appear in the original one that was edited by Anne's father after the war. It also is on superior paper, with very readable type, and the photos are clearly rendered, compared to the other editions I have had in hand.

The industrialization and scale of the murder was unprecedented. Killings were systematically conducted in virtually all areas of occupied Europe—more than 20 occupied countries.[40] Close to three million Jews in occupied Poland and between 700,000 and 2.5 million Jews in the Soviet Union were killed. Hundreds of thousands more died in the rest of Europe.[41] Victims were transported in sealed freight trains from all over Europe to extermination camps equipped with gas chambers.[42] The stationary facilities grew out of Nazi experiments with poison gas during the Aktion T4 mass murder ("euthanasia") programme against the disabled and mentally ill, which began in 1939.[43] The Germans set up six extermination camps in Poland: Auschwitz II-Birkenau (established October 1941); Majdanek (October 1941); Chełmno (December 1941); and the three Operation Reinhard camps, Belzec, Sobibor, and Treblinka, in 1942.[44] A seventh death camp, Maly Trostenets, was established near Minsk in Belarus, then part of the Reichskommissariat Ostland.[45] Discussions at the Wannsee Conference in January 1942 made it clear that the German "final solution of the Jewish question" was intended eventually to include Britain and all the neutral states in Europe, including Ireland, Switzerland, Turkey, Sweden, Portugal, and Spain.[46]
Meanwhile, sightings of Josef Mengele were being reported all over the world. Wiesenthal claimed to have information that placed Mengele on the Greek island of Kythnos in 1960,[103] in Cairo in 1961,[104] in Spain in 1971,[105] and in Paraguay in 1978, eighteen years after he had left the country.[106] He insisted as late as 1985 that Mengele was still alive—six years after he had died—having previously offered a reward of US$100,000 in 1982 for the fugitive's capture.[107] Worldwide interest in the case was heightened by a mock trial held in Jerusalem in February 1985, featuring the testimonies of over one hundred victims of Mengele's experiments. Shortly afterwards, the West German, Israeli, and U.S. governments launched a coordinated effort to determine Mengele's whereabouts. The West German and Israeli governments offered rewards for his capture, as did The Washington Times and the Simon Wiesenthal Center.[108]
In one of the most affecting scenes from Out of the Forest, Zeidel circles the area of the old bunker, looking for the entrance. “Everything was demolished,” he tells the camera, finally, shaking his head in frustration. “Everything. Not that I care it was demolished, but I was certain there would be an opening, even if a blocked one, so I could show you the tunnel.” As it turned out, Zeidel had been standing very close to the tunnel; he just couldn’t know it.
The German skill in adapting the 20th century techniques of mass production was applied in engineering the “Final Solution.” In 1941, the engineers of the “Final Solution” utilized these same principles to cheaply and efficiently murder millions of Jews and other “undesirables.” The plants established to carry out this mass murder were the death camps.
The Roma refer to the genocide of the Romani people as the Pořajmos.[414] Because they are traditionally a private people with a culture based on oral history, less is known about their experience than that of any other group.[415] Bauer writes that this can be attributed to the Roma's distrust and suspicion, and to their humiliation because some of the taboos in Romani culture regarding hygiene and sex were violated at Auschwitz.[416] In May 1942, the Roma were placed under similar laws to the Jews. On 16 December 1942, Himmler issued a decree that "Gypsy Mischlinge [mixed breeds], Roma Gypsies, and members of the clans of Balkan origins who are not of German blood" should be sent to Auschwitz, unless they had served in the Wehrmacht.[417] He adjusted the order on 15 November 1943; in the occupied Soviet areas, "sedentary Gypsies and part-Gypsies are to be treated as citizens of the country. Nomadic Gypsies and part-Gypsies are to be placed on the same level as Jews and placed in concentration camps."[418] Bauer argues that this adjustment reflected Nazi ideology that the Roma, originally an Aryan population, had been "spoiled" by non-Romani blood.[419]

Dr. Mengele was nicknamed the "Angel of Death" by the prisoners because he had the face of an angel, yet he callously made selections for the gas chambers at Birkenau. He was nice to the children in the camp, yet he experimented on them as though they were laboratory rats. He volunteered to do the selections at Birkenau, even when it wasn't his turn, because he wanted to find subjects for his medical research on genetic conditions and hereditary diseases, which he had already begun before the war. He particularly wanted to find twins for the research that he had started before he was posted to Birkenau.
Otto Frank later described what it was like when the Nazis entered the annex in which he had been hiding. He said an SS man picked up a portfolio and asked whether there were any jewels in it. When Otto Frank said it only contained papers, the SS man threw the papers (and Anne Frank’s diary) on the floor, walking away with silverware and a candlestick in his briefcase. “If he had taken the diary with him,” Otto Frank recalled, “no one would ever have heard of my daughter.”

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]
