The Desert Fox of WWII (6)
I believe the answer is:
rommel
'the desert fox of wwii' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for rommel that I've seen before include "Hitler's general known as the Desert Fox" , "Erwin -; Ger. WW 2 field marshal" , "Ger. World War two field marshal" , "Famous German general" , "Erwin --, German general" .)
