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.
Its historical significance makes the term Final Solution the most important example of the ability of Nazi language to integrate potentially different if not divergent approaches towards the so-called Jewish question into a conceptual frame of reference that helped facilitate systematic mass murder and to hide the Third Reich's genocidal policies behind technocratic abstractions, thus providing legitimization for perpetrators and enabling bystanders to claim not to know what was going on. Despite its inherent problems, most notably in evoking the illusion of coordinated planning and systematic implementation, the term Final Solution remains crucial for recognizing the process character of the Holocaust as a key element in a broader history of state-sponsored mass murder during the Nazi era.

The unstoppable Allied military advance continued and on July 24, 1944, Soviet troops liberated the first camp, Majdanek in eastern Poland, where over 360,000 had died. As the Soviet Army neared Auschwitz, Himmler ordered the complete destruction of the gas chambers. Throughout Hitler's crumbling Reich, the SS now began conducting death marches of surviving concentration camp inmates away from outlying areas, including some 66,000 from Auschwitz. Most of the inmates on these marches either dropped dead from exertion or were shot by the SS when they failed to keep up with the column.
To those whose knowledge of the Holocaust consists, essentially, of the fact that Hitler killed the Jews, it often comes as a surprise to learn that, in the first seven and a half years of Nazi rule in Germany, he did no such killing: Jews were not deliberately murdered by the Nazi regime until the invasion of the Soviet Union in June 1941. In Karl Schleunes’ famous phrase, there was a “twisted road to Auschwitz,” with a gradual but by no means direct path to continental genocide. For the first few years of Nazi rule in Germany”Hitler came to power in January 1933 as chancellor and consolidated his rule after the death of President von Hindenburg a year later”Nazi policy aimed “merely” at the removal of Jews from positions of authority, especially in the state sector, with such removal constantly reinforced by the totalitarian regime’s propaganda and its police terrorism. 

In the photo below, Captain Franz Hoessler is standing in front of a load of corpses of prisoners who died from typhus at Bergen-Belsen. He is speaking into a microphone for a documentary film made by the British after the Bergen-Belsen camp was turned over to them by Heinrich Himmler on April 15, 1945. He is wearing his SS uniform, but the insignia of his military rank has been removed. Hoessler was convicted by the British and hanged on December 13, 1945 for war crimes that he had committed at Auschwitz-Birkenau, including his participation in the selection of prisoners to be gassed.
Similar smaller rescue operations occurred in Greece, where Jews were hidden in the mountains or on islands. Later, Greek Jews were smuggled into Turkey. Similar popular aid to the Jews was rendered in Finland and in Holland there was a protest strike in February 1941, against the deportation of Dutch Jews. The Italian army also helped Jews in their occupation zones in France and Yugoslavia, and they played an important role in rescuing Italian Jews before the Germans occupied Italy in September 1943.

Browning’s account of the evolution of the Nazi genocide is the most comprehensive that has yet appeared, and it is no exaggeration to say that the author, who offers here 110 pages of endnotes, has read and absorbed every available document of relevance. Yet one must continue to wonder whether Hitler really waited until August-October 1941 to decide on a policy of genocide. Hitler habitually thought in demographic and social-Darwinist terms, and from 1939 onwards, he was confronted by a new demographic reality”that he now had many millions of Jews under his thumb, far more than the mere five hundred thousand in Nazi Germany in 1933, a figure itself ever-diminishing through emigration. With the conquest of western Poland in mid-1939, over two million Jews came under his rule, while the invasion and conquest of the Soviet Union would add another five million, entirely apart from the many Jews in Nazi satellite states such as Hungary and Romania. It is very difficult to believe that Hitler did not contemplate genocide along with the invasion of the Soviet Union, given the fact that he would soon have the ability to get rid of all of Europe’s Jews in one fell swoop. As Browning carefully notes, as early as February 1941 Hitler remarked to a number of other top Nazis that towards the Jews “he was thinking of many things in a different way, not exactly more friendly.”

Mengele fled Germany to Argentina in 1948, using false documents given to him by the Red Cross. (According to the Mossad’s file, the organization was aware that it was helping a Nazi criminal escape justice.) In Buenos Aires, he lived at first under an assumed name, but later reverted to his own name. He even had a nameplate on his door: Dr. Josef Mengele.

In Lithuania: 34,000. In Latvia: 3,500. In White Russia (excluding Bialystok): 446,484, and in USSR: 5,000,000. Estonia was listed in the minutes as being already Judenfrei (see Wannsee Protocol, Nuremberg).

The vehicle that has most powerfully accomplished this almost universal obtuseness is Anne Frank’s diary. In celebrating Anne Frank’s years in the secret annex, the nature and meaning of her death has been, in effect, forestalled. The diary’s keen lens is helplessly opaque to the diarist’s explicit doom—and this opacity, replicated in young readers in particular, has led to shamelessness.

In France Jews under Fascist Italian occupation in the southeast fared better than the Jews of Vichy France, where collaborationist French authorities and police provided essential support to the understaffed German forces. The Jews in those parts of France under direct German occupation fared the worst. Although allied with Germany, the Italians did not participate in the Holocaust until Germany occupied northern Italy after the overthrow of Fascist leader Benito Mussolini in 1943.
“You want to know about my motivation, don't you? Well. It is the kind of sentiments anyone would have when he actually sees refugees face to face, begging with tears in their eyes. He just cannot help but sympathize with them. Among the refugees were the elderly and women. They were so desperate that they went so far as to kiss my shoes, Yes, I actually witnessed such scenes with my own eyes. Also, I felt at that time, that the Japanese government did not have any uniform opinion in Tokyo. Some Japanese military leaders were just scared because of the pressure from the Nazis; while other officials in the Home Ministry were simply ambivalent.

For the most part, these individuals did not plan to become heroes; the names of the rescuers are largely unrecorded, and their good deeds remain anonymous and unrewarded, except in the emotions of those they saved. They helped by providing hiding places, false papers, food, clothing, money, contact with the outside world, underground escape routes and sometimes even weapons.
^ French Jews were active in the French Resistance.[328] Zionist Jews formed the Armee Juive (Jewish Army), which participated in armed resistance under a Zionist flag, smuggled Jews out of the country,[329] and participated in the liberation of Paris and other cities.[330] As many as 1.5 million Jewish soldiers fought in the Allied armies, including 500,000 in the Red Army, 550,000 in the U.S. Army, 100,000 in the Polish army, and 30,000 in the British army. About 200,000 Jewish soldiers serving in the Red Army died in the war, either in combat or after capture.[331] The Jewish Brigade, a unit of 5,000 Jewish volunteers from the British Mandate of Palestine, fought in the British Army.[332]
 In October 1942, Jan Karski met clandestinely with Jewish leaders at the height of the destruction of Polish Jewry. As a courier for the underground, he delivered their dire message to the Polish government-in-exile in London. “The Jews were abandoned by governments, by church hierarchies, by existing societal structures. But they were not abandoned by all of humanity,” said Karski. “There were thousands upon thousands of people in Europe who risked their life for the Jews. They were priests, nuns, workers, peasants, enlightened ones, simpletons, from all walks of life. They were good people, very simply. We have more good people than probably we think we have in humanity.” Karski was recognized by Yad Vashem as a Righteous Gentile among the Gentiles on June 2, 1982
On May 19th, 1939, the S.S. St. Louis sailed from Hamburg, Germany to Havana, Cuba with 937 passengers; almost all of them were Jews escaping with their lives. This was one of the last ships that left Germany before the outbreak of World War II. Most of the passengers had applied for U.S. visas and were only planning on staying in Cuba until they could enter into the United States. The U.S. State Department in Washington, the U.S. consulate in Havana, and the owner of the St. Louis were aware that they might not be able to enter Cuba, but the passengers were never told.

On September 21, 1939, Reinhard Heydrich ordered the establishment of the Judenräte (“Jewish Councils”), comprising up to 24 men—rabbis and Jewish leaders. Heydrich’s order made these councils personally responsible in “the literal sense of the term” for carrying out German orders. When the Nazis sealed the Warsaw Ghetto, the largest of German-occupied Poland’s 400 ghettos, in the fall of 1940, the Jews—then 30 percent of Warsaw’s population—were forced into 2.4 percent of the city’s area. The ghetto’s population reached a density of more than 200,000 persons per square mile (77,000 per square km) and 9.2 per room. Disease, malnutrition, hunger, and poverty took their toll even before the first bullet was fired.

Bartoszewski was a founder of the Polish resistance who organized an underground organization, comprised mostly of Catholics, to help save Jews. He worked to provide false documents to Jews living outside the Warsaw ghetto. In the fall of 1942, he helped found an organization (Council for Aid to Jews) which successfully saved many Jews from the gas chambers. Bartoszweski was actually imprisoned in the Auschwitz Concentration Camp between 1940 and 1941, and after his release was secured by the Red Cross he reported on the camp.

In May, Nazis under the direction of SS Lt. Colonel Adolf Eichmann boldly began a mass deportation of the last major surviving population of European Jews. From May 15 to July 9, over 430,000 Hungarian Jews were deported to Auschwitz. During this time, Auschwitz recorded its highest-ever daily number of persons killed and cremated at just over 9000. Six huge open pits were used to burn the bodies, as the number of dead exceeded the capacity of the crematories.

Over the next two years, Anne wrote faithfully in the diary, which she came to consider a friend, addressing many of the entries to “Dear Kitty.” In the journal and later notebooks, Anne recounted the day-to-day life within the annex. The close quarters and sparse supplies led to various arguments among the inhabitants, and the outgoing Anne came to find the conditions stifling. Heightening tensions was the ever-present concern that they would be discovered. However, many entries involve typical adolescent issues—jealousy toward her sister; annoyance with others, especially her mother; and an increasing sexual awareness. Anne wrote candidly about her developing body, and she experienced a brief romance with Peter van Pels. She also discussed her hopes for the future, which included becoming a journalist or a writer. In addition to the diary, Anne penned several short stories and compiled a list of “beautiful sentences” from other works.
David Cesarani emphasises the improvised, haphazard nature of Nazi policies in response to changing war time conditions in his overview, Final Solution: The Fate Of The European Jews 1933–49 (2016). "Cesarani provides telling examples", wrote Mark Roseman, "of a lack of coherence and planning for the future in Jewish policy, even when we would most expect it. The classic instance is the invasion of Poland in 1939, when not even the most elementary consideration had been given to what should happen to Poland's Jews either in the shorter or longer term. Given that Poland was home to the largest Jewish population in the world, and that, in a couple of years, it would house the extermination camps, this is remarkable."[118]

Mengele sailed to Argentina in July 1949, assisted by a network of former SS members. He initially lived in and around Buenos Aires, then fled to Paraguay in 1959 and Brazil in 1960, while being sought by West Germany, Israel, and Nazi hunters such as Simon Wiesenthal who wanted to bring him to trial. He eluded capture in spite of extradition requests by the West German government and clandestine operations by the Israeli intelligence agency Mossad. He drowned in 1979 after suffering a stroke while swimming off the Brazilian coast, and was buried under a false name. His remains were disinterred and positively identified by forensic examination in 1985.
