Prepare for conflict (8)
I believe the answer is:
embattle
'prepare for conflict' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for embattle that I've seen before include "strengthen the defence" , "Arrange in readiness for conflict" , "Make ready to fight; belt mate (anagram)" , "add strength" , "Fortify" .)
