During World War II the main camp was supplemented by about 150 branches scattered throughout southern Germany and Austria, all of which collectively were called Dachau. (This southern system complemented the camps for central and northern Germany, at Buchenwald and Sachsenhausen.) In the course of Dachau’s history, at least 160,000 prisoners passed through the main camp, and 90,000 through the branches. Incomplete records indicate that at least 32,000 of the inmates died there from disease, malnutrition, physical oppression, and execution, but countless more were transported to the extermination camps in German-occupied Poland.
The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as millions of others, including Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler’s “final solution”–now known as the Holocaust–came to fruition under the cover of world war, with mass killing centers constructed in the concentration camps of occupied Poland.

The Commander enters the room where prisoners are mending boots and reads aloud an article on the situation in the concentration camp in Dachau, taken from the Vienna Arbeiter Zeitung. The paper states the prisoners are beaten with oxtails and shot “when caught in the attempt to escape” or are found “hanging in their cells.” Every prisoner knows that the report is true. The Commander asks: “Are you now convinced of the lies published by this Marxist Jewish press?” No one answers.
Demographic statistics vary but they are in the same general range. History will likely never know how many people were interned or died there, due to periods of disruption. One source gives a general estimate of over 200,000 prisoners from more than 30 countries for the Third Reich's years, of whom two-thirds were political prisoners, including many Catholic priests, and nearly one-third were Jews. 25,613 prisoners are believed to have died in the camp and almost another 10,000 in its subcamps,[16] primarily from disease, malnutrition and suicide. In late 1944, a typhus epidemic occurred in the camp caused by poor sanitation and overcrowding, which caused more than 15,000 deaths.[17] It was followed by an evacuation, in which large numbers of the prisoners died. Toward the end of the war, death marches to and from the camp caused the deaths of numerous unrecorded prisoners. After liberation, prisoners weakened beyond recovery by the starvation conditions continued to die.[18] Two thousand cases of "the dread black typhus" had already been identified by 3 May, and the U.S. Seventh Army was "working day and night to alleviate the appalling conditions at the camp".[19] Prisoners with typhus, a louse-borne disease with an incubation period from 12 to 18 days, were treated by the 116th Evacuation Hospital, while the 127th would be the general hospital for the other illnesses. There were 227 documented deaths among the 2,252 patients cared for by the 127th.[18]
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.
For the first time, camps were created specifically for Jews. Their conditions were far worse than other camps. The implicit intention was that the inmates would die there. Increasing numbers of Jews in Poland were relocated in ghettos. Non-Jewish Poles were also deported from their farms and villages to make room for ‘pure’ ethnic Germans to populate the new territory.
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.[6] 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.[6] 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.
