Like some battles (6)
I believe the answer is:
uphill
'like some battles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for uphill that I've seen before include "Towards a slope's top" , "Ascending - arduous" , "Difficult situation" , "Sloping upwards" , "This going is tough, but climb on" .)
