In the manuscript, her original diaries are written over three extant volumes. The first volume (the red-and-white checkered autograph book) covers the period between June 14 and December 5, 1942. Since the second surviving volume (a school exercise book) begins on December 22, 1943, and ends on April 17, 1944, it is assumed that the original volume or volumes between December 1942 and December 1943 were lost - presumably after the arrest, when the hiding place was emptied on Nazi instructions. However, this missing period is covered in the version Anne rewrote for preservation. The third existing volume (which was also a school exercise book) contains entries from April 17 to August 1, 1944, when Anne wrote for the last time before her arrest.:2

After 1942, the economic functions of the camps, previously secondary to their penal and terror functions, came to the fore. Forced labor of camp prisoners became commonplace. The guards became much more brutal, and the death rate increased as the guards not only beat and starved prisoners, but killed them more frequently. Vernichtung durch Arbeit ("extermination through labor") was a policy—camp inmates would literally be worked to death, or to physical exhaustion, at which point they would be gassed or shot. The Germans estimated the average prisoner's lifespan in a concentration camp at three months, due to lack of food and clothing, constant epidemics, and frequent punishments for the most minor transgressions. The shifts were long and often involved exposure to dangerous materials.
In October 1941 the Nazis began turning the concentration camp at Majdanek into a death camp as well. They then began the construction of killing centres at Bełżec, Treblinka, near Warsaw, and at Sobibór. The first mass gassing of Jews began in Chelmno on 8 December 1941, when the Nazis used gas vans to murder people from the Łódź ghetto. The Nazis also ordered the expansion of the Auschwitz camp complex to increase the capacity for murder.
The next year, 1942, marked the beginning of mass murder on a scale unprecedented in all of human history. In January, fifteen top Nazis led by Reinhard Heydrich, second in command of the SS, convened the Wannsee Conference in Berlin to coordinate plans for the Final Solution. The Jews of Europe would now be rounded up and deported into occupied Poland where new extermination centers were being constructed at Belzec, Sobibor, Treblinka, and Auschwitz-Birkenau.
Hitler targeted the Jews for a specific reason, which was not just racial. The elimination of the Jews had a unique “status” in Hitler’s master plan. While he certainly killed millions of others (gypsies, communists, homosexuals, etc.) he made exceptions for all these groups. The only group for which no exception was made was the Jews—they all had to die.
In June 1941, Mengele was posted to Ukraine, where he was awarded the Iron Cross 2nd Class. In January 1942, he joined the 5th SS Panzer Division Wiking as a battalion medical officer. After rescuing two German soldiers from a burning tank, he was decorated with the Iron Cross 1st Class, the Wound Badge in Black, and the Medal for the Care of the German People. He was declared unfit for further active service in mid-1942, when he was seriously wounded in action near Rostov-on-Don. Following his recovery, he was transferred to the headquarters of the SS Race and Settlement Main Office in Berlin, at which point he resumed his association with von Verschuer, who was now director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmführer (captain) in April 1943.
