To battle, starting with the attacker, each player alternates turns in which they declare an opposing piece to attack and roll a die. If the number rolled (including any combat advantage) equals or exceeds the attacked piece's strength, the attacked piece is removed from the board. An attacker may attack with more than one legion at a time, and from more than one direction. Only the attacking forces have the option of retreating to their original position(s) (with each general having their own option). If a force has been completely destroyed, the losing general(s) is/are captured by the ultimate winner of the battle, and the loser's triremes destroyed, although the die must be rolled for this to occur in a naval battle, and a trireme can only be attacked after all legions have been destroyed.
