Immediately upon arriving at Dachau, the process of dehumanizing prisoners began. Men and women were stripped of all possessions including their clothes which were replaced with striped uniforms. Their hair was shaved and they were given an identification number with a colored triangle to show their category.13 Dachau was a labor camp, most of the many sub-camps of Dachau were built with slave labor. The Nazis exploited the cheap labor by hiring out prisoners to private firms. Prisoners never received their wages, as the private firms paid the Nazis directly for the labor. The work was often heavy labor and the weakened and malnourished prisoners were given little food and lived in unsanitary conditions.
The camp was liberated on April 15, 1945, by the British 11th Armoured Division. The soldiers discovered approximately 60,000 prisoners inside, most of them half-starved and seriously ill, and another 13,000 corpses, including those of Anne and Margot Frank, lying around the camp unburied. The horrors of the camp, documented on film and in pictures, made the name "Belsen" emblematic of Nazi crimes in general for public opinion in many countries in the immediate post-1945 period. Today, there is a memorial with an exhibition hall at the site.
