Shelter a US general (3)
I believe the answer is:
lee
I believe this clue is a double definition.
'shelter' is the first definition.
(thesaurus)
'a us general' is the second definition.
(Other definitions for lee that I've seen before include "The sheltered side of something" , "Revolutionary general" , "Commander of the Confederate States Army in the American Civil War" , "Confederate general" , "Cork river" .)
