Skorzeny joined the Nazi Party in 1933 and became a colonel in the Waffen SS during World War II. In 1944 he played a leading part in the roundup and torture of anti-Hitler conspirators after the failure of the July 20 assassination plot. On Oct. 17, 1944, he led an SS unit to the Budapest royal palace and arrested the Hungarian leader Adm. Miklos Horthy. In the course of the Germans' Ardennes offensive during Christmas week 1944, Skorzeny directed the infiltration of hundreds of English-speaking Germans clad in U.S. uniforms behind the Allied lines. After the war he was acquitted by the International Military Tribunal (1947) in Nürnberg on the testimony of a British officer who maintained that Skorzeny had done nothing that his Allied counterparts would not have attempted. While awaiting a West German denazification trial in 1949, he escaped from Darmstadt prison and spent his remaining years in Spain.
