+110.+ Next morning the two Consuls broke up their camp, and advanced to where they heard that the enemy were entrenched. On the second day they arrived within sight of them, and pitched their camp at about fifty stades’ distance. But when Aemilius observed that the ground was flat and bare for some distance round, he said that they must not engage there with an enemy superior to them in cavalry; but that they must rather try to draw him off, and lead him to ground on which the battle would be more in the hands of the infantry. But Gaius Terentius being, from inexperience, of a contrary opinion, there was a dispute and misunderstanding between the leaders, which of all things is the most dangerous. It is the custom, when the two Consuls are present, that they should take the chief command on alternate days; and the next day happening to be the turn of Terentius, he ordered an advance with a view of approaching the enemy, in spite of the protests and active opposition of his colleague. Hannibal set his light-armed troops and cavalry in motion to meet him, and charging the Romans while they were still marching, took them by surprise and caused a great confusion in their ranks. The Romans repulsed the first charge by putting some of their heavy-armed in front; and then sending forward their light-armed and cavalry, began to get the best of the fight all along the line: the Carthaginians having no reserves of any importance, while certain companies of the legionaries were mixed with the Roman light-armed, and helped to sustain the battle. Nightfall for the present put an end to a struggle which had not at all answered to the hopes of the Carthaginians. But next day Aemilius, not thinking it right to engage, and yet being unable any longer to lead off his army, encamped with two-thirds of it on the banks of the Aufidus, the only river which flows right through the Apennines,—that chain of mountains which forms the watershed of all the Italian rivers, which flow either west to the Tuscan sea, or east to the Hadriatic. This chain is, I say, pierced by the Aufidus, which rises on the side of Italy nearest the Tuscan Sea, and is discharged into the Hadriatic. For the other third of his army he caused a camp to be made across the river, to the east of the ford, about ten stades from his own lines, and a little more from those of the enemy; that these men, being on the other side of the river, might protect his own foraging parties, and threaten those of the enemy.
