Scipio and the Carthaginians

When Scipio deployed his troops, he concentrated the core of the legions in the center and placed his Spanish allies on the wings. The opposing Carthaginian general got used to this formation and placed his strongest troops in the center with weaker Spanish mercenaries on the wing. But when Scipio decided to fight, however, he switched things up. He ordered out his cavalry early in the morning to attack the Carthaginian camp. In a reverse of the previous battle, it was the Carthaginians who were roused from their beds and forced to charge without a good breakfast.
