Of the children involved, only about 200 were alive when the camp was liberated by the Soviet Army on January 27, 1945. These are the children shown so often in documentaries walking between the wires of the Auschwitz I camp. Today they reside all over the world and they seek information on what was done to them. Their files have never been located and what was done to them remains a mystery today.
Begin thought settling the score with Mengele would show Palestinian leaders (and the Israeli public) that they would have to pay a price for harming Israelis. His attitude was reflected in a message he sent to President Ronald Reagan when he sent the Israeli Army into Lebanon in 1982, saying that he felt as if “I have sent an army to Berlin to wipe out Hitler in the bunker.”
The Chelmno killing center begins operation. The Nazis later establish five other such camps: Belzec, Sobibor, Treblinka, Auschwitz-Birkenau (part of the Auschwitz complex), and Majdanek. Victims at Chelmno are killed in gas vans (hermetically sealed trucks with engine exhaust diverted to the interior compartments). The Belzec, Sobibor, and Treblinka camps use carbon monoxide gas generated by stationary engines attached to gas chambers. Auschwitz-Birkenau, the largest of the killing centers, has four large gas chambers using Zyklon B (crystalline hydrogen cyanide) as the killing agent. The gas chambers at Majdanek use both carbon monoxide and Zyklon B. Millions of Jews are killed in the gas chambers in the killing centers as part of the "Final Solution."
Anti-Jewish measures were introduced in Slovakia, which would later deport its Jews to German concentration and extermination camps.[175] Bulgaria introduced anti-Jewish measures in 1940 and 1941, including the requirement to wear a yellow star, the banning of mixed marriages, and the loss of property. Bulgaria annexed Thrace and Macedonia, and in February 1943 agreed to deport 20,000 Jews to Treblinka; all 11,000 Jews from the annexed territories were sent to their deaths, and plans were made to deport an additional 6,000–8,000 Bulgarian Jews from Sofia to meet the quota.[176] When the plans became public, the Orthodox Church and many Bulgarians protested, and King Boris III canceled the deportation of Jews native to Bulgaria.[177] Instead, they were expelled to the interior pending further decision.[176] Although Hungary expelled Jews who were not citizens from its newly annexed lands in 1941, it did not deport most of its Jews[178] until the German invasion of Hungary in March 1944. Between 15 May and 9 July 1944, 440,000 Hungarian Jews were deported to Auschwitz.[179] In late 1944 in Budapest, nearly 80,000 Jews were killed by the Hungarian Arrow Cross battalions.[180]

Methods of mass murder evolved at local levels as well as being decreed from Nazi high command. Killing squads rounded up and shot entire Jewish communities. Over two days in Kiev, 33,771 Jews were shot. The murder of Jews rapidly escalated, in part because local Nazi leaders didn’t have enough room to place them in the ghettos. By the end of the year, plans to implement the systematic slaughter of Jews by using gas in mobile trucks and gas chambers were well underway.
A German mother shields the eyes of her son as they walk with other civilians past a row of exhumed bodies outside Suttrop, Germany. The bodies were those of 57 Russians killed by German SS troops and dumped in a mass grave before the arrival of troops from the U.S. Ninth Army. Soldiers of the 95th Infantry division were led by informers to the massive grave on May 3, 1945. Before burial, all German civilians in the vicinity were ordered to view the victims. #
Wounded while on campaign, Mengele returned to Germany in January 1943. He began work at the Kaiser Wilhelm Institute (KWI) for Anthropology, Human Genetics, and Eugenics, directed by his former mentor von Verschuer. In April of 1943, he received a promotion to the rank of SS captain. This promotion shortly preceded Mengele's transfer to Auschwitz, on May 30, 1943.
Upon arrival at a camp in mates were stripped of their clothes and shaved of all their body hair. Then they were given a shower, disinfected and given a uniform. each step was used to dehumanize prisoners, both physically and emotionally. Prisoners were then given a number. At Auschwitz the number was tattooed on their arm. Those who the Nazis thought were unable to work were token to what they called showers. The Nazis said to these prisoners who were about to meet their deaths it was to freshen up a bit after their long journey. Instead of water Zyklon B, developed to kill rodents, closed in on them. Death Did not usually come quickly but rather slowly. Most of the walls of the death chambers had scratch marks to show how victims tried to dig themselves out. The purpose of these cams were to kill huge amounts of Jews a day. Camps had been in Germany for years. These were the places  were tons of Jews had been murdered. Once at the camps selected people would work the others were gassed. Before being gassed they forced to march to the sound of music. An important camp was Treblinka. It was established for slave labor In 1941, but in 1942 it became a death camp. By may 1943 the population of Warsaw had been transported to Treblinka and other camps. By July 11, 1944 800,000 Jews had been murdered in Treblinkia. Unlike Treblinkia, Chelmno, Sobibor, and Balzac which were made to kill Jews. Maidanek and Auschwitz had a work camp attached. Upon arrival at these two camps a selection was made. 10% of the new arrivals would escape immediate gassing.

Bureaucrats in the Reichsbahn performed important functions that facilitated the movement of trains. They constructed and published timetables, collected fares, and allocated cars and locomotives. In sending Jews to their death, they did not deviate much from the routine procedures they used to process ordinary train traffic.
The Germans required each ghetto to be run by a Judenrat, or Jewish council.[205] Councils were responsible for a ghetto's day-to-day operations, including distributing food, water, heat, medical care, and shelter. The Germans also required councils to confiscate property, organize forced labor, and, finally, facilitate deportations to extermination camps.[206] The councils' basic strategy was one of trying to minimize losses, by cooperating with German authorities, bribing officials, and petitioning for better conditions or clemency.[207]
Mengele was an attractive man. A perennial little smile showed the gap between his front teeth. Immaculately dressed in jodhpurs, he wore a cap bearing the SS insignia and carried the obligatory riding crop, constantly slapping it against his gleaming black boots. Whenever he spoke to me, he was very polite, giving the impression that he was interested in me. It was hard to believe that his little smile and courteous behavior were just a facade behind which he devised the most horrific murderous schemes.
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.
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]
Those who were not considered fit for work were taken immediately by truck from the Judenrampe to two make-shift gas chambers at Birkenau, which were located in two converted farm houses called "the little red house" and "the little white house." At least 75% of the Jews in each transport of 2,000 to 3,000 prisoners were deemed unfit for work and were destined for the gas chamber. The little red house, also known as Bunker 1, had a capacity of 800 people in two rooms and the little white house, called Bunker 2, had a capacity of 1,200 in four rooms.
The worst example was the pogrom in the town of Kielce in Poland on July 4th, 1946. When the 200 surviving Jews returned to their village, the local Poles who were upset to see that any had survived instigated a blood libel—accusing the Jews of the kidnap and ritual murder of Polish child. In the ensuing violence 40 of the Jews, all Holocaust survivors, were murdered by the Polish towns people.
For Kanin, this kind of rumination was “an embarrassing piece of special pleading. . . . The fact that in this play the symbols of persecution and oppression are Jews is incidental, and Anne, in stating the argument so, reduces her magnificent stature.” And so it went throughout. The particularized plight of Jews in hiding was vaporized into what Kanin called “the infinite.” Reality—the diary’s central condition—was “incidental.” The passionately contemplative child, brooding on concrete evil, was made into an emblem of evasion. Her history had a habitation and a name; the infinite was nameless and nowhere.
By the spring of 1942, the Nazis had established six killing centers (death camps) in Poland: Chelmno (Kulmhof), Belzec, Sobibor, Treblinka, Maidanek and Auschwitz. All were located near railway lines so that Jews could be easily transported daily. A vast system of camps (called Lagersystem) supported the death camps. The purpose of these camps varied: some were slave labor camps, some transit camps, others concentration camps and their sub­camps, and still others the notorious death camps. Some camps combined all of these functions or a few of them. All the camps were intolerably brutal.

The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people.[16] Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.[17]
