The 500th was led by "Hauptsturmführer" Kurt Rybka during its daring but unsuccessful parachute and glider-borne assault on Tito's headquarters outside Drvar on 25 May 1944. The raid was called Operation Rösselsprung (Knight's move). Two companies were dropped directly on Tito's supposed headquarters location while the other two were landed by DFS 230 glider.
