The conflict was obstinate. And here Marcus, the son of Cato, and son-in-law of Aemilius, whilst he showed all possible courage, let fall his sword. Being a young man carefully brought up and disciplined, and, son of so renowned a father, bound to give proof of more than ordinary virtue, he thought his life but a burden, should he live and permit his enemies to enjoy this spoil. He hurried hither and thither, and wherever he espied a friend or companion, declared his misfortune, and begged their assistance; a considerable number of brave men being thus collected, with one accord they made their way through their fellows after their leader, and fell upon the enemy; whom after a sharp conflict, many wounds, and much slaughter, they repulsed, possessed the place that was now deserted and free, and set themselves to search for the sword, which at last they found covered with a great heap of arms and dead bodies.
Overjoyed with this success, they raised the song of triumph, and, with more eagerness than ever, charged the foes that yet remained firm and unbroken. In the end, three thousand of the chosen men, who kept their ground and fought valiantly to the last, were all cut in pieces, while the slaughter of such as fled was also very great. The plain and the lower part of the hills were filled with dead bodies, and the water of the river Leucus, which the Romans did not pass till the next day after the battle, was then mingled with blood. For it is said there fell more than twenty-five thousand of the enemy; of the Romans, as Posidonius relates, a hundred; as Nasica, only fourscore. This battle, though so great, was very quickly decided, it being three in the afternoon when they first engaged, and not four when the enemy was vanquished; the rest of the day was spent in pursuit of the fugitives, whom they followed about thirteen or fourteen miles, so that it was far in the night when they returned.
All the others were met by their servants with torches, and brought back with joy and great triumph to their tents, which were set out with lights, and decked with wreaths of ivy and laurel. But the general himself was in great grief. Of the two sons that served under him in the war, the youngest was missing, whom he held most dear, and whose courage and good qualities he perceived much to excel those of his brothers. Bold and eager for distinction, and still a mere child in age, he concluded that he had perished, whilst for want of experience he had engaged himself too far amongst his enemies.
His sorrow and fears became known to the army; the soldiers, quitting their suppers, ran about with lights, some to Aemilius's tent, some out of the trenches, to seek him amongst such as were slain in the first onset. There was nothing but grief in the camp, and the plain was filled with the cries of men calling out for Scipio; for, from his very youth, he was an object of admiration; endowed above any of his equals with the good qualities requisite either for command or counsel. At length, when it was late, and they almost despaired, he returned from the pursuit with only two or three of his companions all covered with the fresh blood of his enemies, having been, like some dog of noble breed, carried away by the pleasure, greater than he could control, of his first victory. This was that Scipio that afterwards destroyed Carthage and Numantia, and was, without dispute, the first of the Romans in merit, and had the greatest authority amongst them. Thus Fortune, deferring her displeasure and jealousy of such great success to some other time, let Aemilius at present enjoy this victory, without any detraction or diminution.
