After the German surrender on May 7, 1945, the American Army took over the barracks of the SS garrison and set up a command post called Eastman which they occupied until 1973. On the orders of General Dwight D. Eisenhower, all available American soldiers were brought to Dachau so that they could be eye-witnesses to the existence of the homicidal gas chamber, disguised as a shower room.
When British and Canadian troops finally entered they found over 13,000 unburied bodies and (including the satellite camps) around 60,000 inmates, most acutely sick and starving. The prisoners had been without food or water for days before the Allied arrival, partially due to allied bombing. Immediately before and after liberation, prisoners were dying at around 500 per day, mostly from typhus. The scenes that greeted British troops were described by the BBC's Richard Dimbleby, who accompanied them:
September 26, 1942 - SS begins cashing in possessions and valuables of Jews from Auschwitz and Majdanek. German banknotes are sent to the Reichs Bank. Foreign currency, gold, jewels and other valuables are sent to SS Headquarters of the Economic Administration. Watches, clocks and pens are distributed to troops at the front. Clothing is distributed to German families. By February 1943, over 800 boxcars of confiscated goods will have left Auschwitz.
Since March 1945, around 15,000 new prisoners had been accommodated in a camp that was originally designed for 5,000 men. By the time the liberators arrived, there were over 30,000 prisoners in the camp. There was a typhus epidemic in the camp but the Germans had no DDT, nor typhus vaccine, available to stop it. Up to 400 prisoners per day were dying of typhus by the time that the Americans arrived. There was no coal to burn the bodies in the ovens and the staff could not keep up with burying the bodies in mass graves on a hill several miles from the camp.
Georg Elser, who was imprisoned at Dachau as a suspect in the attempted assassination of Hitler on November 8, 1939, was allegedly shot around the time that an Allied bomb hit the camp on April 9, 1945 and his death was blamed on the bombing. General Charles Delestraint, a Dachau prisoner who had been the leader of the French Secret Army in the Resistance, was allegedly executed at Dachau on April 19, 1945, although no execution order from Berlin was ever found. Four female British SOE agents were also allegedly executed Dachau, although the execution order was never found.
After this night, the German government supported dozens of laws and decrees that took away Jews property and livelihood. By the end of the year, Jews were prohibited from attending school. One billion reichsmarks of Jewish property was seized as collective punishment against the nation’s Jews for the murder of von Rath. Those able to flee the country did. In the year after Kristallnact, more than 100,000 Jews left Germany as the situation deteriorated.
On April 21, 1945, the evacuation of the camp began. The prisoners were first deloused and then moved into the barracks of the German Army Training Center next to the camp. Two days later, 6 detachments of the Red Cross arrived to help. The epidemics had yet to be brought under control and 400 to 500 prisoners were still dying each day, but by April 28, the German guards had caught up with the burial of the bodies and the mass graves were completed.
With the invasion of the Soviet Union on June 22 1941, the Nazis launched a crusade against 'Judaeo-Bolshevism', the supposed Jewish-Communist conspiracy. Behind the front lines, four police battalions called Einsatzgruppen (operations groups) moved from town to town in the newly occupied Soviet territories, rounding up Jewish men and suspected Soviet collaborators and shooting them. In subsequent sweeps, making heavy use of local volunteers, the Einsatzgruppen targeted Jewish women and children as well. In total, the Einsaztgruppen murdered some two million people, almost all Jews.
On April 29, 1945, SS 2nd Lt. Heinrich Wicker surrendered the camp to the 42nd Rainbow Division of the US Seventh Army, which had found the camp on its way to take the city of Munich, 18 kilometers to the south. Accompanied by Red Cross representative Victor Maurer, 2nd Lt. Wicker surrendered the Dachau concentration camp to Brigadier General Henning Linden, commander of the 42nd Rainbow Division, under a white flag of truce. The 45th Thunderbird Division of the US Seventh Army also participated in the liberation of Dachau, arriving at the nearby SS garrison before the 42nd Division approached the installations's main entrance on the south side of the Dachau complex where 2nd Lt. Wicker was waiting to surrender the camp.
On 24 April 1945, just days before the U.S. troops arrived at the camp, the commandant and a strong guard forced between 6,000 and 7,000 surviving inmates – on a death march from Dachau south to Eurasburg, then eastwards towards the Tegernsee; liberated two days after Hitler's death by a Nisei-ethnicity U.S. Army artillery battalion. Any prisoners who could not keep up on the six-day march were shot. Many others died of exhaustion, hunger and exposure. Months later a mass grave containing 1,071 prisoners was found along the route.
The camp of huts near Fallingbostel became known as Stalag XI-B and was to become one of the Wehrmacht's largest POW camps, holding up to 95,000 prisoners from various countries. In June 1940, Belgian and French POWs were housed in the former Bergen-Belsen construction workers' camp. This installation was significantly expanded from June 1941, once Germany prepared to invade the Soviet Union, becoming an independent camp known as Stalag XI-C (311). It was intended to hold up to 20,000 Soviet POWs and was one of three such camps in the area. The others were at Oerbke (Stalag XI-D (321)) and Wietzendorf (Stalag X-D (310)). By the end of March 1942, some 41,000 Soviet POWs had died in these three camps of starvation, exhaustion, and disease. By the end of the war, the total number of dead had increased to 50,000. When the POW camp in Bergen ceased operation in early 1945, as the Wehrmacht handed it over to the SS, the cemetery contained over 19,500 dead Soviet prisoners.
