Custer's last stand (6,7)

I believe the answer is:
little bighorn
'custer's last stand' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for little bighorn that I've seen before include "native American success" , "Scene of Custer's Last Stand, 1876" , "Site of Custer's defeat" , "Custer's final battle" .)
