Cato, perceiving the danger, commanded all the rest to halt, and stay where they were, whilst he himself, taking along with him one Lucius Manlius, a most expert man at climbing mountains, went forward with a great deal of labour and danger, in the dark night, and without the least moonshine, among the wild olive-trees and steep craggy rocks, there being nothing but precipices and darkness before their eyes, till they struck into a little pass which they thought might lead down into the enemy's camp. There they put up marks upon some conspicuous peaks which surmount the hill called Callidromon, and, returning again, they led the army along with them to the said marks, till they got into their little path again, and there once made a halt; but when they began to go further, the path deserted them at a precipice, where they were in another strait and fear; nor did they perceive that they were all this while near the enemy. And now the day began to give some light, when they seemed to hear a noise, and presently after to see the Greek trenches and the guard at the foot of the rock. Here, therefore, Cato halted his forces, and commanded the troops from Firmum only, without the rest, to stick by him, as he had always found them faithful and ready. And when they came up and formed around him in close order, he thus spoke to them: "I desire,"he said, "to take one of the enemy alive, that so I may understand what men these are who guard the passage; their number; and with what discipline, order, and preparation they expect us; but this feat," continued he, "must be an act of a great deal of quickness and boldness, such as that of lions, when they dart upon some timorous animal." Cato had no sooner thus expressed himself, but the Firmans forthwith rushed down the mountain, just as they were, upon the guard, and, falling unexpectedly upon them, affrighted and dispersed them all. One armed man they took, and brought to Cato, who quickly learned from him that the rest of the forces lay in the narrow passage about the king; that those who kept the tops of the rocks were six hundred choice Aetolians. Cato, therefore, despising the smallness of their number and carelessness, forthwith drawing his sword, fell upon them with a great noise of trumpets and shouting. The enemy, perceiving them thus tumbling, as it were, upon them from the precipices, flew to the main body, and put all things into disorder there.
In the meantime, whilst Manius was forcing the works below, and pouring the thickest of his forces into the narrow passages, Antiochus was hit in the mouth with a stone, so that his teeth being beaten out by it, he felt such excessive pain, that he was fain to turn away with his horse; nor did any part of his army stand the shock of the Romans. Yet, though there seemed no reasonable hope of flight, where all paths were so difficult, and where there were deep marshes and steep rocks, which looked as if they were ready to receive those who should stumble, the fugitives, nevertheless, crowding and pressing together in the narrow passages, destroyed even one another in their terror of the swords and blows of the enemy. Cato (as it plainly appears) was never oversparing of his own praises, and seldom shunned boasting of any exploit; which quality, indeed, he seems to have thought the natural accompaniment of great actions; and with these particular exploits he was highly puffed up; he says that those who saw him that day pursuing and slaying the enemies were ready to assert that Cato owed not so much to the public as the public did to Cato; nay, he adds, that Manius the consul, coming hot from the fight, embraced him for a great while, when both were all in a sweat; and then cried out with joy that neither he himself, no, nor all the people together, could make him a recompense equal to his actions. After the fight he was sent to Rome, that he himself might be the messenger of it: and so, with a favourable wind, he sailed to Brundusium, and in one day got from thence to Tarentum; and having travelled four days more, upon the fifth, counting from the time of his landing, he arrived at Rome, and so brought the first news of the victory himself; and filled the whole city with joy and sacrifices, and the people with the belief that they were able to conquer every sea and every land.
