+12.+ All arrangements for the battle being complete, and the two opposing forces of Numidian cavalry having been for some time engaged in skirmishing attacks upon each other, Hannibal gave the word to the men on the elephants to charge the enemy. But as they heard the horns and trumpets braying all round them, some of the elephants became unmanageable and rushed back upon the Numidian contingents of the Carthaginian army; and this enabled Massanissa with great speed to deprive the Carthaginian left wing of its cavalry support. The rest of the elephants charged the Roman velites in the spaces between the maniples of the line, and while inflicting much damage on the enemy suffered severely themselves; until, becoming frightened, some of them ran away down the vacant spaces, the Romans letting them pass harmlessly along, according to Scipio’s orders, while others ran away to the right under a shower of darts from the cavalry, until they were finally driven clear off the field. It was just at the moment of this stampede of the elephants, that Laelius forced the Carthaginian cavalry into headlong flight, and along with Massanissa pressed them with a vigorous pursuit. While this was going on, the opposing lines of heavy infantry were advancing to meet others with deliberate step and proud confidence, except Hannibal’s “army of Italy,” which remained in its original position. When they came within distance the Roman soldiers charged the enemy, shouting as usual their war-cry, and clashing their swords against their shields: while the Carthaginian mercenaries uttered a strange confusion of cries, the effect of which was indescribable, for, in the words of the poet,[61] the “voice of all was not one”—
“nor one their cry: But manifold their speech as was their race.”

+13.+ The whole affair being now a trial of strength between man and man at close quarters, as the combatants used their swords and not their spears, the superiority was at first on the side of the dexterity and daring of the mercenaries, which enabled them to wound a considerable number of the Romans. The latter, however, trusting to the steadiness of their ranks and the excellence of their arms, still kept gaining ground, their rear ranks keeping close up with them and encouraging them to advance; while the Carthaginians did not keep up with their mercenaries nor support them, but showed a thoroughly cowardly spirit. The result was that the foreign soldiers gave way: and, believing that they had been shamelessly abandoned by their own side, fell upon the men on their rear as they were retreating, and began killing them; whereby many of the Carthaginians were compelled to meet a gallant death in spite of themselves. For as they were being cut down by their mercenaries they had, much against their inclination, to fight with their own men and the Romans at the same time; and as they now fought with desperation and fury they killed a good many both of their own men and of the enemy also. Thus it came about that their charge threw the maniples of the hastati into confusion; whereupon the officers of the principes caused their lines to advance to oppose them. However, the greater part of the mercenaries and Carthaginians had fallen either by mutual slaughter or by the sword of the hastati. Those who survived and fled Hannibal would not allow to enter the ranks of his army, but ordered his men to lower their spears and keep them back as they approached; and they were therefore compelled to take refuge on the wings or make for the open country.
