Accordingly, on the first charge, the Romans immediately drove back the line of their opponents; then pushing them with their elbows and the bosses of their shields, and pressing forward into the places from which they had pushed them, they advanced a considerable space, as though there had been no one to resist them, those who formed the rear urging forward those in front when they perceived the line of the enemy giving way; which circumstance itself gave great additional force in repelling them.

On the side of the enemy, the second line, consisting of the Africans and Carthaginians, were so far from supporting the first line when giving ground, that, on the contrary, they even retired, lest their enemy, by slaying those who made a firm resistance, should penetrate to themselves also.

Accordingly, the auxiliaries suddenly turned their backs, and facing about upon their own party, fled, some of them into the second line, while others slew those who did not receive them into their ranks, since before they did not support them, and now refused to receive them.

And now there were, in a manner, two contests going on together, the Carthaginians being compelled to fight at once with the enemy and with their own party.

Not even then, however, did they receive into their line the terrified and exasperated troops; but, closing their ranks, drove them out of the scene of action to the wings and the surrounding plain, lest they should mingle these soldiers, terrified with defeat and wounds, with that part of their line which was firm and fresh.
