The play who wins the game retains his original territory and selects either of the two remaining territories to add to his own. This will be his rival's territory or the new one. The loser takes the territory that is left.
If the winner takes his rival's territory the loser is assumed to have been forced back into the newly generated territory. If the winner takes the new territory then the battle has determined which side will possess this new land.
In the event of a draw both sides retain their territories and the player with the least territory gains a new one. If both players have the same amount of territory roll a dice to decide who gets the new territory.
