Otto Johann Anton Skorzeny was an Austrian-born German SS-Standartenführer in the Waffen-SS during World War II. During the war, he was involved in a number of operations, including the removal from power of Hungarian Regent Miklós Horthy and the Gran Sasso raid that rescued Benito Mussolini from captivity. Skorzeny led Operation Greif in which German soldiers infiltrated Allied lines wearing their enemies' uniforms. As a result, he was charged in 1947 at the Dachau Military Tribunal with breaching the 1907 Hague Convention, but was acquitted.
