The Carthaginian line was deprived of the cavalry on both sides, when the infantry, who were now not a match for the Romans in confidence or strength, engaged. In addition to this there was one circumstance, trifling in itself, but at the same time producing important consequences in the action. On the part of the Romans the shout was uniform, and on that account louder and more terrific; while the voices of the enemy, consisting as they did of many nations of different languages, were dissonant. The Romans used the stationary kind of fight, pressing upon the enemy with their own weight and that of their arms; but on the other side there was more of skirmishing and rapid movement than force. 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 tho 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.
