Romans were defeated also because of their odd way of electing generals who took decisions about each and everything. Each Roman consul is actually the Supreme commander of his army and both decide who will be in charge and for what days. Hannibal knows about the temperament of Sempronius thus taking advantage of that situation.  

This second Punic war happened to be so famous because of the blood oaths and vengeance, rivalry from two houses, and because of the war has passed down to father to his son. And two bloodlines were vying for the fate of world history.
