19. After an interval of two years, Pyr'rhus, having increased his army by new levies, sent one part of it to oppose the march of Len'tulus, while he, with the other, went to attack Cu'rius Denta'tus, before his colleague could come up. 20. His principal aim was to surprise the enemy by night; but unfortunately, passing through woods, and the light failing him, his men lost their way; so that at the approach of morning, he saw himself in sight of the Roman camp, with the enemy drawn out ready to receive him. The vanguard of both armies soon met, in which the Romans had the advantage. 21. Soon after, a general engagement ensuing, Pyr'rhus, finding the balance of the victory turning still against him, had once more recourse to his elephants. 22. These, however, the Romans were now too well acquainted with, to feel any vain terrors from; and having found that fire was the most effectual means to repel them, they caused a number of balls to be made, composed of flax and rosin, which were lighted and thrown against them as they approached the ranks. 23. The elephants, rendered furious by the flame, and boldly opposed by the soldiers, could no longer be brought on; but ran back on their own army, bearing down their ranks, and filling all places with terror and confusion: thus victory, at length, declared in favour of Rome. 24. Pyr'rhus, in vain, attempted to stop the flight and slaughter of his troops; he lost not only twenty-three thousand of his best soldiers, but his camp was also taken. 25. This served as a new lesson to the Romans, who were ever open to improvement. They had formerly pitched their tents without order; but, by this new capture, they were taught to measure out their ground, and fortify the whole with a trench; so that many of their succeeding victories are to be ascribed to their improved method of encamping. 26. Pyr'rhus, thus finding all hopes fruitless, resolved to leave Italy, where he found only desperate enemies, and faithless allies; accordingly, calling together the Taren'tines, he informed them that he had received assurances from Greece of speedy assistance, and desiring them to await the event with tranquillity, the night following he embarked his troops, and returned, undisturbed, into his native kingdom, with the remains of his shattered forces, leaving a garrison in Taren'tum merely to save appearances: and in this manner ended the war with Pyr'rhus, after six years' continuance.
