Apache military leader whose third surrender to an American general was his last (8)
I believe the answer is:
geronimo
(Other definitions for geronimo that I've seen before include "helicopter paratroops' departure call?" , "war-cry" , "One 15 [PLAYING] 24 33 [AT SIXES AND SEVENS]" , "he's called for the high jump?" , "C19 Apache chief" .)
