The British military authorities ordered the construction of a permanent memorial in September 1945 after having been lambasted by the press for the desolate state of the camp.:41 In the summer of 1946, a commission presented the design plan, which included the obelisk and memorial walls. The memorial was finally inaugurated in a large ceremony in November 1952, with the participation of Germany's president Theodor Heuss, who called on the Germans never to forget what had happened at Belsen.:41
One prisoner, Aaron, son of a Bamberg attorney, died of his injuries a few days later. The official cause of death, which in every other case was agreed upon between the camp commanders and the Special Police, could not in this case be made to appear as “Shot while trying to escape,” or “Found hanged in his cell,” since the body showed no marks of shooting or hanging. The Commander, however, found a way out of this fix: that very night the shed in which the corpse was laid out was burned down. The corpse was sufficiently scorched to destroy the marks of the beating, and the official announcement read, “Died of heart disease.” The body was delivered to the parents in a sealed coffin.
Gun did not explain how these 300 prisoners died on the night of the liberation of the camp, but he did write that the prisoners had weapons and that the International Committee of Dachau had made sure that the prisoners who had cooperated with the German guards were not allowed to escape. Others may have died from eating too much of the canned food and chocolate given to them by the Americans, and undoubtedly there were deaths among the 900 prisoners sick with typhus in the infirmary.
In October 1939 Hitler signed a "euthanasia decree" backdated to 1 September 1939 that authorized Reichsleiter Philipp Bouhler, the chief of Hitler's Chancellery, and Karl Brandt, Hitler's personal physician, to carry out a program of involuntary "euthanasia"; after the war this program was named Aktion T4. It was named after Tiergartenstraße 4, the address of a villa in the Berlin borough of Tiergarten, where the various organizations involved were headquartered. T4 was mainly directed at adults, but the "euthanasia" of children was also carried out. Between 1939 and 1941, 80,000 to 100,000 mentally ill adults in institutions were killed, as were 5,000 children and 1,000 Jews, also in institutions. In addition there were specialized killing centres, where the deaths were estimated at 20,000, according to Georg Renno, the deputy director of Schloss Hartheim, one of the "euthanasia" centers, or 400,000, according to Frank Zeireis, the commandant of the Mauthausen concentration camp. Overall, the number of mentally and physically handicapped murdered was about 150,000.
On January 20, 1942, Reinhard Heydrich convened the Wannsee Conference at a lakeside villa in Berlin to organize the “final solution to the Jewish question.” Around the table were 15 men representing government agencies necessary to implement so bold and sweeping a policy. The language of the meeting was clear, but the meeting notes were circumspect:
The death marches served a dual purpose for the Nazis. On one hand, the Nazis intended for large numbers of Jewish prisoners to die on death marches. Indeed, about 250,000 prisoners, many of whom were Jews, died on death marches. On the other hand, the death marches were also an attempt to move concentration camp prisoners into Germany's borders, so that the Nazis could continue to exploit them for slave labor. Those who survived the death marches were imprisoned in concentration camps in Germany, such as Bergen Belsen, Ravensbrueck and Mauthausen.
On 26 April 1945 prisoner Karl Riemer fled the Dachau concentration camp to get help from American troops and on 28 April Victor Maurer, a representative of the International Red Cross, negotiated an agreement to surrender the camp to U.S. troops. That night a secretly formed International Prisoners Committee took over the control of the camp. Units of 3rd Battalion, 157th Infantry Regiment, 45th Infantry Division, commanded by Lieutenant Colonel Felix L. Sparks, were ordered to secure the camp. On 29 April Sparks led part of his battalion as they entered the camp over a side wall. At about the same time, Brigadier General Henning Linden led the 222nd Infantry Regiment of the 42nd (Rainbow) Infantry Division soldiers including his aide, Lieutenant William Cowling, to accept the formal surrender of the camp from German Lieutenant Heinrich Wicker at an entrance between the camp and the compound for the SS garrison. Linden was traveling with Marguerite Higgins and other reporters, as a result, Linden's detachment generated international headlines by accepting the surrender of the camp. More than 30,000 Jews and political prisoners were freed, and since 1945 adherents of the 42nd and 45th Division versions of events have argued over which unit was the first to liberate Dachau.:201:283
After 1945 the name was applied to the displaced persons camp established nearby, but it is most commonly associated with the concentration camp. From 1941 to 1945, almost 20,000 Soviet prisoners of war and a further 50,000 inmates died there. Overcrowding, lack of food and poor sanitary conditions caused outbreaks of typhus, tuberculosis, typhoid fever and dysentery, leading to the deaths of more than 35,000 people in the first few months of 1945, shortly before and after the liberation.
