Skorzeny, in a daring "snatch" codenamed Operation Panzerfaust (known as "Operation Eisenfaust" in Germany), kidnapped Horthy's son Miklós Horthy Jr. and forced his father to resign as head of state. A pro-Nazi government under dictator Ferenc Szálasi was then installed in Hungary. In April 1945, after German and Hungarian forces had already been driven out of Hungary, Szálasi and his Arrow Cross Party-based forces continued the fight in Austria and Slovakia. The success of the operation earned Skorzeny promotion to Obersturmbannführer.
