Half of casualties return; the loser retreats, surrenders half its returnees as prisoners and loses abandoned guns.
How it works
Half of all casualties (rounded down) return right after the battle. Cannon abandoned or overrun become the victor's, half usable from the next map turn. A battle lasts until one side concedes; the loser gets one free retreat march and gives half its returnees as prisoners. If neither concedes after at least 24 turns before nightfall, both are treated as losers.
If neither side concedes defeat, and a minimum of 24 turns have gone b/, then night falls, both sides consider they are the losers, and take a free march away.
