Another aspect of ancient warfare was the importance of the leader in the battles. It was not unusual for Alma to engage with Amlici. It is probable that they were distinguished by battle flags or clothing so that their own armies, and also their enemies, would know where they were. It is also not unusual that the victor in this individual battle would be considered the victor in the overall battle.
Thus, Alma and Amlici face each other directly. Although this sounds like a battle of champions, it appears that the battle continued around them. They were the important focus, but not the sole combatants.
