When the Gauls drew near, about the river Anio, dragging a heavy camp after them, and loaded with infinite spoil, Camillus drew forth his forces, and planted himself upon a hill of easy ascent, and which had many dips in it, with the object that the greatest part of his army might lie concealed, and those who appeared might be thought to have betaken themselves, through fear, to those upper grounds. And the more to increase this opinion in them, he suffered them, without any disturbance, to spoil and pillage even to his very trenches, keeping himself quiet within his works, which were well fortified; till, at last, perceiving that part of the enemy were scattered about the country foraging, and that those that were in the camp did nothing day and night but drink and revel, in the night time he drew up his lightest-armed men, and sent them out before to impede the enemy while forming into order, and to harass them when they should first issue out of the their camp; and early in the morning brought down his main body, and set them in battle array in the lower round, numerous and courageous army, not, as the barbarians had supposed, an inconsiderable and fearful division. The first thing that shook the courage of the Gauls was, that their enemies had, contrary to their expectation, the honor of being aggressors. In the next place, the light-armed men, falling upon them before they could get into their usual order or range themselves in their proper squadrons, so disturbed and pressed upon them, that they were obliged to fight at random, without any order at all. But at last, when Camillus brought on his heavy-armed legions, the barbarians, with their swords drawn, went vigorously to engage them; the Romans, however, opposing their javelins, and receiving the force of their blows on those parts of the defences which were well guarded with steel, turned the edge of their weapons, beingmade of a soft and ill-tempered metal, so that their swords bent and doubled up in their hands; and their shields were pierced through and through, and grew heavy with the javelins that stuck upon them. And thus forced to quit their own weapons, they endeavored to take advantage of those of their enemies, laid hold of the javelins with their hands, and tried to pluck them away. But the Romans, perceiving them now naked and defenceless, betook themselves to their swords, which they so well used, that in a little time great slaughter was made in the foremost ranks, while the rest fled over all parts of the level country; the hills and upper grounds Camillus had secured beforehand, and their camp they knew it would not be difficult for the enemy to take, as, through confidence of victory, they had left it unguarded. This fight, it is stated, was thirteen years after the sacking of Rome; and from henceforward the Romans took courage, and surmounted the apprehensions they had hitherto entertained of the barbarians, whose previous defeat they had attributed rather to pestilence and a concurrence of mischances than to their own superior valor. And, indeed, this fear had been formerly so great, that they made a law, that priests should be excused from service in war, unless in an invasion from the Gauls.
This was the last military action that Camillus ever performed;for the voluntary surrender of the city of the Velitrani was but a mere accessory to it. But the greatest of all civil contests, and the hardest to be managed, was still to be fought out against the people; who, returning home full of victory and success, insisted, contrary to established law, to have one of the consuls chosen out of their own body. The senate strongly opposed it, and would not suffer Camillus to lay down his dictatorship, thinking, that, under the shelter of his great name and authority, they should be better able to contend for the power of the aristocracy. But when Camillus was sitting upon the tribunal, dispatching public affairs, an officer, sent by the tribunes of the people, commanded him to rise and follow him, laying his and upon him, as ready to seize and carry him away; upon which, such a noise and tumult as was never heard before, filled the whole forum; some that were about Camillus thrusting the officer from the bench, and the multitude below calling out to him to bring Camillus down. Being at a loss what to do in these difficulties, he yet laid not down his authority, but, taking the senators along with him, he went to the senate-house; but before he entered, besought the gods that they would bring these troubles to a happy conclusion, solemnly vowing, when the tumult was ended, to build a temple to Concord. Agreat conflict of opposite opinions arose in the senate; but, at last, the most moderate and most acceptable to the people prevailed, and consent was given, that of two consuls, one should be chosen from the commonalty. When the dictator proclaimed this determination of the senate to the people, at the moment pleased and reconciled with the senate, as they could not well otherwise be, they accompanied Camillus home with all expressions and acclamations of joy; and the next day, assembling together, they voted a temple of Concord to be built, according to Camillus's vow, facing the assembly and the forum; and to the feasts, called the Latin holidays, they added one day more, making four in all;and ordained that, on the present occasion the whole people of Rome should sacrifice with garlands on their heads.
In the election of consuls held by Camillus, Marcus Aemilius was chosen of the patricians, and Lucius Sextius the first of the commonalty; and this was the last of all Camillus's actions. In the year following, a pestilential sickness infected Rome, which, besides an infinite number of the common people, swept away most of the magistrates, among whom was Camillus; whose death cannot be called premature, if we consider his great age, or greater actions, yet was he more lamented than all the rest put together that then died of that distemper.
