Camillus, on his arrival, found twenty thousand of them ready in arms;with which forces, and those confederates he brought along with him, he prepared to set upon the enemy.
But at Rome some of the barbarians, passing by chance near the place at which Pontius by night had got into the Capitol, spied in several places marks of feet and hands, where he had laid hold and clambered, and places where the plants that grew to the rock had been rubbed off, and the earth had slipped, and went accordingly and reported it to the king, who, coming in person, and viewing it, for the present said nothing, but in the evening, picking out such of the Gauls as were nimblest of body, and by living in the mountains were accustomed to climb, he said to them, "The enemy themselves have shown us a way how to come at them, which we knew not of before, and have taught us that it is not so difficult and impossible but that men may overcome it. It would be a great shame, having begun well, to fail in the end, and to give up a place as impregnable, when the enemy himself lets us see the way by which it may be taken; for where it was easy for one man to get up, it will not be hard for many, one after another; nay, when many shall undertake it, they will be aid and strength to each other. Rewards and honours shall be bestowed on every man as he shall acquit himself."When the king had thus spoken, the Gauls cheerfully undertook to perform it, and in the dead of night a good party of them together, with great silence, began to climb the rock, clinging to the precipitous and difficult ascent, which yet upon trial offered a way to them, and proved less difficult than they had expected. So that the foremost of them having gained the top of all, and put themselves into order, they all but surprised the outworks, and mastered the watch, who were fast asleep; for neither man nor dog perceived their coming. But there were sacred geese kept near the temple of Juno, which at other times were plentifully fed, but now, by reason that corn and other provisions were grown scarce for all, were but in a poor condition. The creature is by nature of quick sense, and apprehensive of the least noise, so that these, being moreover watchful through hunger, and restless, immediately discovered the coming of the Gauls, and, running up and down with their noise and cackling, they raised the whole camp, while the barbarians on the other side, perceiving themselves discovered, no longer endeavoured to conceal their attempt, but with shouting and violence advanced to the assault. The Romans, every one in haste snatching up the next weapon that came to hand, did what they could on the sudden occasion. Manlius, a man of consular dignity, of strong body and great spirit, was the first that made head against them, and, engaging with two of the enemy at once, with his sword cut off the right arm of one just as he was lifting up his blade to strike, and, running his target full in the face of the other, tumbled him headlong down the steep rock; then mounting the rampart, and there standing with others that came running to his assistance, drove down the rest of them, who, indeed, to begin, had not been many, and did nothing worthy of so bold an attempt. The Romans, having thus escaped this danger, early in the morning took the captain of the watch and flung him down the rock upon the heads of their enemies, and to Manlius for his victory voted a reward, intended more for honour than advantage, bringing him, each man of them as much as he received for his daily allowance, which was half a pound of bread and one eighth of a pint of wine.
Henceforward, the affairs of the Gauls were daily in a worse and worse condition; they wanted provisions, being withheld from foraging through fear of Camillus, and sickness also was amongst them, occasioned by the number of carcasses that lay in heaps unburied.
