World War II: A death march from Dachau to the Austrian border[1] is halted by the segregated, all-Nisei 522nd Field Artillery Battalion of the U.S. Army in southern Bavaria, saving several hundred prisoners.[2]

Dachau () was the first concentration camp built by Nazi Germany, opening on 22 March 1933. The camp was initially intended to intern Hitler's political opponents which consisted of: communists, social democrats, and other dissidents. It is located on the grounds of an abandoned munitions factory northeast of the medieval town of Dachau, about 16 km (10 mi) northwest of Munich in the state of Bavaria, in southern Germany. After its opening by Heinrich Himmler, its purpose was enlarged to include forced labor, and, eventually, the imprisonment of Jews, Romani, German and Austrian criminals, and, finally, foreign nationals from countries that Germany occupied or invaded. The Dachau camp system grew to include nearly 100 sub-camps, which were mostly work camps or Arbeitskommandos, and were located throughout southern Germany and Austria. The main camp was liberated by U.S. forces on 29 April 1945.

Prisoners lived in constant fear of brutal treatment and terror detention including standing cells, floggings, the so-called tree or pole hanging, and standing at attention for extremely long periods. There were 32,000 documented deaths at the camp, and thousands that are undocumented. Approximately 10,000 of the 30,000 prisoners were sick at the time of liberation.In the postwar years, the Dachau facility served to hold SS soldiers awaiting trial. After 1948, it held ethnic Germans who had been expelled from eastern Europe and were awaiting resettlement, and also was used for a time as a United States military base during the occupation. It was finally closed in 1960.

There are several religious memorials within the Memorial Site, which is open to the public.

During the Holocaust, death marches (Todesmärsche in German) were massive forced transfers of prisoners from one Nazi camp to other locations, which involved walking long distances resulting in numerous deaths of weakened people. Most death marches took place toward the end of World War II, mostly after the summer/autumn of 1944. Hundreds of thousands of prisoners, mostly Jews, from Nazi camps near the Eastern Front were moved to camps inside Germany away from the Allied forces. Their purpose was to continue the use of prisoners' slave labour, to remove evidence of crimes against humanity, and to keep the prisoners for bargaining with the Allies.Prisoners were marched to train stations, often a long way; transported for days at a time without food in freight trains; then forced to march again to a new camp. Those who lagged behind or fell were shot. The largest death march took place in January 1945. Nine days before the Soviet Red Army arrived at the Auschwitz concentration camp, the Germans marched 56,000 prisoners toward a train station at Wodzisław, 35 miles (56 km) away, to be transported to other camps. Around 15,000 died on the way.Earlier marches of prisoners, also known as "death marches", include those in 1939 in the Lublin Reservation, Poland, and in 1942 in Reichskommissariat Ukraine.
