 Along the hill-bordered skirts of the lake, Hannibal camped where he was in full view of anyone entering the northern defile, and spent the night arranging his troops for battle.Below the camp, he placed his heavy infantry (Iberians and Africans) upon a slight elevation.Here, they had ample ground from which they could charge down upon the head of the Roman column on the left flank, when it should reach the position.
