Dachau Camp was officially described as "the first concentration camp for political prisoners" by Heinrich Himmler. Behind its fences the murderous SS policies, epidemics and starvation claimed thousands of lives. This program, the first of two focusing on the Dachau camp, shows the true horrors of the Nazi regime, from the infamous shower rooms to the crematorium that ran day and night disposing of human remains.

The Dachau concentration camp was established in 1933 and operated continuously until the end of the war in 1945. It was the first concentration camp of the Nazi regime and it is estimated that at least 188,000 prisoners were incarcerated there between 1933 and 1945.

As Allied and Soviet troops moved across Europe in a series of offensives against Nazi Germany, they encountered concentration camps, mass graves, and numerous other sites of Nazi crimes. American soldiers witnessed evidence of the Holocaust and Nazi atrocities as they marched into the interior of Germany, liberating the major concentration camps such as Buchenwald, Dachau, and Mauthausen as well as hundreds of subcamps, including Ohrdruf (a subcamp of Buchenwald). Though the liberation of Nazi camps was not a primary objective of the Allied military campaign, U.S, British, Canadian, and Soviet troops freed prisoners from their SS guards, provided them with food and badly needed medical support, and collected evidence for war crimes trials.
