By August 1945, Pernkopf is captured by United States Army forces and imprisoned at Glasenbach camp (the US called this Camp Marcus W Orr). This camp was not in Glasenbach, rather it was in Salzburg and originall run by the US military. This camp was an internment camp. Pernkopf was detained as a NSDAP member and Nazi sympathizer. Many people at Camp Marcus W Orr were awaiting trial for war crimes and the rest of the prisoners were handed over to the Austrian government in 1947.
