Hasdrubal's elephants were ten in number. We have no trustworthy information as to the amount of his infantry, but it is quite clear that he was greatly outnumbered by the combined Roman forces.

The tactic of the Roman legions had not yet acquired that perfection which it received from the military genius of Marius, and which we read of in the first chapter of Gibbon. We possess, in that great work, an account of the Roman legions at the end of the commonwealth, and during the early ages of the empire, which those alone can adequately admire who have attempted a similar description. We have also, in the sixth and seventeenth books of Polybius, an elaborate discussion on the military system of the Romans in his time, which was not far distant from the time of the battle of the Metaurus. But the subject is beset with difficulties; and instead of entering into minute but inconclusive details, I would refer to Gibbon's first chapter as serving for a general description of the Roman army in its period of perfection, and remark, that the training and armor which the whole legion received in the time of Augustus was, two centuries earlier, only partially introduced.

The sword was carried on the right thigh, and was a short cut-and-thrust weapon, like that which was used by the Spaniards. Thus armed, the Hastati formed
