And now, the siege of the Capitol having lasted a good while, the Gauls began to be in want of provision; and dividing their forces, part of them stayed with their king at the siege, the rest went to forage the country, ravaging the towns and villages where they came, but not all together in a body, but in different squadrons and parties; and to such a confidence had success raised them, that they carelessly rambled about without the least fear or apprehension of danger. But the greatest and best ordered body of their forces went to the city of Ardea, where Camillus then sojourned, having, ever since his leaving Rome, sequestered himself from all business, and taken to a private life; but now he began to rouse up himself, and consider not how to avoid or escape the enemy, but to find out an opportunity to be revenged upon them. And perceiving that the Ardeatians wanted not men, but rather enterprise, through the inexperience and timidity of their officers, he began to speak with the young men, first to the effect that they ought not to ascribe the misfortune of the Romans to the courage of their enemy, nor attribute the losses they sustained by rash counsel to the conduct of men who had no title to victory; the event had been only an evidence of the power of fortune; that it was a brave thing even with danger to repel a foreign and barbarous invader whose end in conquering was, like fire, to lay waste and destroy, but if they would be courageous and resolute he was ready to put an opportunity into their hands to gain a victory, without hazard at all. When he found the young men embraced the thing, he went to the magistrates and council of the city, and, having persuaded them also, he mustered all that could bear arms, and drew them up within the walls, that they might not be perceived by the enemy, who was near; who, having scoured the country, and returned heavy-laden with booty, lay encamped in the plains in a careless and negligent posture, so that, with the night ensuing upon debauch and drunkenness, silence prevailed through all the camp. When Camillus learned this from his scouts, he drew out the Ardeatians, and in the dead of the night, passing in silence over the ground that lay between, came up to their works, and, commanding his trumpets to sound and his men to shout and halloo, he struck terror into them from all, quarters; while drunkenness impeded and sleep retarded their movements. A few, whom fear had sobered, getting into some order, for a while resisted; and so died with their weapons in their hands. But the greatest part of them, buried in wine and sleep, were surprised without their arms, and despatched; and as many of them as by the advantage of the night got out of the camp were the next day found scattered abroad and wandering in the fields, and were picked up by the horse that pursued them.
The fame of this action soon fled through the neighbouring cities, and stirred up the young men from various quarters to come and join themselves with him. But none were so much concerned as those Romans who escaped in the battle of Allia, and were now at Veii, thus lamenting with themselves, "O heavens, what a commander has Providence bereaved Rome of, to honour Ardea with his actions! And that city, which brought forth and nursed so great a man, is lost and gone, and we, destitute of a leader and shut up within strange walls, sit idle, and see Italy ruined before our eyes. Come, let us send to the Ardeatians to have back our general, or else, with weapons in our hands, let us go thither to him; for he is no longer a banished man, nor we citizens, having no country but what is in the possession of the enemy." To this they all agreed, and sent to Camillus to desire him to take the command; but he answered, that he would not, until they that were in the Capitol should legally appoint him; for he esteemed them, so long as they were in being, to be his country;that if they should command him he would readily obey; but against their consent he would intermeddle with nothing. When this answer was returned, they admired the modesty and temper of Camillus; but they could not tell how to find a messenger to carry the intelligence to the Capitol, or rather, indeed, it seemed altogether impossible for any one to get to the citadel whilst the enemy was in full possession of the city. But among the young men there was one Pontius Cominius, of ordinary birth, but ambitious of honour, who proffered himself to run the hazard, and took no letters with him to those in the Capitol, lest, if he were intercepted, the enemy might learn the intentions of Camillus; but, putting on a poor dress and carrying corks under it, he boldly travelled the greatest part of the way by day, and came to the city when it was dark; the bridge he could not pass, as it was guarded by the barbarians; so that taking his clothes, which were neither many nor heavy, and binding them about his head, he laid his body upon the corks, and swimming with them, got over to the city. And avoiding those quarters where he perceived the enemy was awake, which he guessed at by the lights and noise, he went to the Carmental gate, where there was greatest silence, and where the hill of the Capitol is steepest and rises with craggy and broken rock. By this way he got up, though with much difficulty, by the hollow of the cliff, and presented himself to the guards, saluting them, and telling them his name; he was taken in, and carried to the commanders. And a senate being immediately called, he related to them in order the victory of Camillus, which they had not heard of before, and the proceedings of the soldiers, urging them to confirm Camillus in the command, as on him alone all their fellow-countrymen outside the city would rely. Having heard and consulted of the matter, the senate declared Camillus dictator, and sent back Pontius the same way that he came, who, with the same success as before, got through the enemy without being discovered, and delivered to the Romans outside the decision of the senate, who joyfully received it.
