All prisoners underwent the same fate when they entered the camp, they lost their legal status, their remaining possessions were confiscated, their hair was shaved off, and they were dressed in striped clothes. They were allocated a number as well as a coloured triangle, indicating what type of category they belonged to. The daily routine was filled with work, hunger, exhaustion, and fear of the brutality of the sadistic SS guards.
Although not ordered to take part, psychiatrists and many psychiatric institutions were involved in the planning and carrying out of Aktion T4 at every stage.[103] After protests from the German Catholic and Protestant churches, Hitler ordered the cancellation of the T4 program in August 1941,[104] although the disabled and mentally ill continued to be killed until the end of the war.[102] The medical community regularly received bodies and body parts for research. Eberhard Karl University received 1,077 bodies from executions between 1933 and 1945. The neuroscientist Julius Hallervorden received 697 brains from one hospital between 1940 and 1944: "I accepted these brains of course. Where they came from and how they came to me was really none of my business."[105]

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.[76] 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,[77] 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.[30]:201[78]:283[79][80][81]
They built roads, worked in gravel pits, and drained marshes, reclaiming them as arable land, initially, production in the camps was directly under the control of the individual camp commandant. But as the camps continued to grow, the range of production expanded, and the SS industries that were served by the camp labour were centralised under their main office in Berlin. In the first winter of the war the Dachau camp was used to set up the SS Totenkopf Division.
I was surprised to find records, going back for two or three years, of large quantities of food cooked daily for distribution. I became convinced, contrary to popular opinion, that there had never been a policy of deliberate starvation. This was confirmed by the large numbers of well-fed inmates. Why then were so many people suffering from malnutrition? [...]
The first Jewish prisoners came as known political opponents of the Nazis. At Dachau, as elsewhere, they received even worse treatment than the other prisoners. Gradually, more and more groups were arrested and brought to Dachau, Jehovah’s Witness, Gypsies, who like the Jews were classified as racially inferior, Clergymen who resisted the Nazi coercion of the churches and Homosexuals and many others who had been denounced for making critical remarks against the Nazi regime.
When the Nazi’s rose to power they built facilities to hold and, eventually kill, their enemies. When the first concentration camps were built in 1933, this primarily meant political dissidents and opponents of the Nazi government, such as German Communists, Socialists, Social Democrats but would grow to include asocial groups – Gypsies, Jehovah’s Witnesses, the homeless, the mentally ill and homosexuals.  It was not until Kristallnacht that the prisoners became primarily Jewish.

In the aftermath of the Holocaust, many of the survivors found shelter in displaced persons  camps administered by the Allied powers. Between 1948 and 1951, almost 700,000 Jews emigrated to Israel, including 136,000 Jewish displaced persons from Europe. Other Jewish displaced persons emigrated to the United States and other nations. The last camp for Jewish displaced persons closed in 1957.

Like the network of concentration camps that followed, becoming the killing grounds of the Holocaust, Dachau was under the control of Heinrich Himmler, head of the elite Nazi guard, the Schutzstaffel (SS), and later chief of the German police. By July 1933, German concentration camps (Konzentrationslager in German, or KZ) held some 27,000 people in “protective custody.” Huge Nazi rallies and symbolic acts such as the public burning of books by Jews, Communists, liberals and foreigners helped drive home the desired message of party strength.
From 1945 until 1950, when it was finally shut down, the British maintained Belsen as a camp for displaced European Jews. During this period it achieved new notoriety as a major European black market center. The "uncrowned king" of Belsen's 10,000 Jews was Yossl (Josef) Rosensaft, who amassed tremendous profits from the illegal trading. Rosensaft had been interned in various camps, including Auschwitz, before arriving in Belsen in early April 1945. /42
The German view of the Roma as hereditary criminals and "asocials" was reflected in their classification in the concentration camps, where they were usually counted among the asocials and given black triangles to wear.[420] According to Niewyk and Nicosia, at least 130,000 died out of nearly one million in German-occupied Europe.[415] The United States Holocaust Memorial Museum calculates at least 220,000.[421] Ian Hancock, who specializes in Romani history and culture, argues for between 500,000 and 1,500,000.[422] The treatment of the Roma was not consistent across German-occupied territories. Those in France and the Low Countries were subject to restrictions on movement and some confinement to collection camps, while those in Central and Eastern Europe were sent to concentration camps and murdered by soldiers and execution squads.[423] Before being sent to the camps, the Roma were herded into ghettos, including several hundred into the Warsaw Ghetto.[219] Further east, teams of Einsatzgruppen tracked down Romani encampments and murdered the inhabitants on the spot, leaving no records of the victims.[423] After the Germans occupied Hungary, 1,000 Roma were deported to Auschwitz.[424][x]
Instead, Marcel Goldberg, a Jewish “clerk” assigned to the new Plaszow commandant Arnold Buscher, played the largest role in compiling the transport list. It is generally agreed that Buscher, an SS officer, “could not have cared, within certain numerical limits, who went on the list,” according to Thomas Keneally. It’s also agreed that Goldberg engaged in a certain amount of corruption in who he added to the list and, moreover, that there was not even one “list” but rather different lists that emerged over a series of months.
On 15 September 1935, the Reichstag passed the Reich Citizenship Law and the Law for the Protection of German Blood and German Honor, known as the Nuremberg Laws. The former said that only those of "German or kindred blood" could be citizens. Anyone with three or more Jewish grandparents was classified as a Jew.[107] The second law said: "Marriages between Jews and subjects of the state of German or related blood are forbidden." Sexual relationships between them were also criminalized; Jews were not allowed to employ German women under the age of 45 in their homes.[108] The laws referred to Jews but applied equally to the Roma and black Germans.[107]
A tablet at the camp commemorates the liberation of Dachau by the 42nd Infantry Division of the U.S. Seventh Army on 29 April 1945. Others claim that the first forces to enter the main camp were a battalion of the 157th Infantry Regiment of the 45th Infantry Division commanded by Felix L. Sparks. There is an on-going disagreement as to which division, the 42nd or the 45th, actually liberated Dachau because they seem to have approached by different routes and by the American Army’s definition, anyone arriving at such a camp within 48 hours was a liberator. General Patton visited the Buchenwald camp after it was liberated, but not Dachau.

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.
In 1988, West Germany allocated another $125 million for reparations. Companies such as BMW, Deutsche Bank, Ford, Opel, Siemens, and Volkswagen faced lawsuits for their use of forced labor during the war.[463] In response, Germany set up the "Remembrance, Responsibility and Future" Foundation in 2000, which paid €4.45 billion to former slave laborers (up to €7,670 each).[465] In 2013, Germany agreed to provide €772 million to fund nursing care, social services, and medication for 56,000 Holocaust survivors around the world.[466] The French state-owned railway company, the SNCF, agreed in 2014 to pay $60 million to Jewish-American survivors, around $100,000 each, for its role in the transport of 76,000 Jews from France to extermination camps between 1942 and 1944.[467]
The first commander of Dachau, Hilmar Wäckerle, was dismissed from his position by Heinrich Himmler after charges of murder were brought against him by a Munich court for the deaths of several prisoners who had died after being severely punished. Another Dachau Commandant, Alex Piorkowski, was also dismissed by Himmler and was expelled from the Nazi party for breaking the strict rules set by Eicke.
The ramp appeared to lead up to the crematorium ovens. I am not surprised that the commandant and the guards were not charged with gassing prisoners because the evidence had been destroyed by the British, but that was academic because they had enough evidence to hang Kramer and Grese a hundred times over. As my Dad's colonel said to him: "They'll have a legal trial and a legal hanging..."

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.[3] 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.
