I'm a little stuck... Click here to teach me more about this clue!

'battle' is the definition.
(I know that battle can be written as fight)

(Other definitions for fight that I've seen before include "Attack or engage in combat" , "Brawl; argue" , "Campaign against - quarrel" , "Box" , "Conflict" .)

I've seen this clue in The Guardian.
