It was a shock that was barely descriptive even for the combat-tested soldiers of the US Army when on May 5, 1945 in a forest south of the municipality of Gunskirchen came into a concentration camp that had not been known until then: the forest floor was covered with hundreds of corpses. Of the over 5000 living prisoners, some of which were next to the corpses, more than 1000 should die in the next few days. The Gunskirchen concentration camp was also freed, an outer warehouse in Mauthausen.
