Stolo was much distinguished by the victory he had gained; but, not long after, was found himself to possess more than he had allowed to others, and suffered the penalties of his own law.
And now the contention about election of consuls coming on (which was the main point and original cause of the dissension, and had throughout furnished most matter of division between the senate and the people), certain intelligence arrived, that the Gauls again, proceeding from the Adriatic Sea, were marching in vast numbers upon Rome. On the very heels of the report followed manifest acts also of hostility; the country through which they marched was all wasted, and such as by flight could not make their escape to Rome were dispersing and scattering among the mountains. The terror of this war quieted the sedition; nobles and commons, senate and people together unanimously chose Camillus the fifth time dictator; who, though very aged, not wanting much of fourscore years, yet, considering the danger and necessity of his country, did not, as before, pretend sickness, or depreciate his own capacity, but at once undertook the charge and enrolled soldiers. And, knowing that the great force of the barbarians lay chiefly in their swords, with which they laid about them in a rude and inartificial manner, hacking and hewing the head and shoulders, he caused head-pieces entire iron to be made for most of his men, smoothing and polishing the outside, that the enemy's swords, lighting upon them, might either slide off or be broken; and fitted also their shields with a little rim of brass, the wood itself not being sufficient to bear off the blows. Besides, he taught his soldiers to use their long javelins in close encounter, and, by bringing them under their enemy's swords, to receive their strokes upon them.
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 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 their camp; and early in the morning brought down his main body, and set them in battle array in the lower grounds, a 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 honour 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 their defences which were well guarded with steel, turned the edge of their weapons, being made of 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 struck upon them. And thus forced to quit their own weapons, they endeavoured 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 valour. 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 Gaul.
