I think I might have posted too soon. From reading Lancer's post, if I understand it correctly, Mago is across the river and Hannibal is approaching. Therefore, Hannibal is still there, but he has not arrived just yet.

This is correct. The force on our side of the river needs to be defeated, before Hannibal can get his army across.
