This terrible tidings put an end to all internal disputes. The Senate and people formed themselves into one assembly, and with one voice appointed Camillus dictator for the fifth time. He was now a very old man, being near his eightieth year; but at this pressing crisis he made none of his former excuses, but at once took the chief command and levied an army for the war. As he knew that the chief power of the Gauls lay in their swords, with which they dealt heavy blows on the heads and shoulders of their enemy, without any skill in fence, he prepared for most of his soldiers helmets made entirely of smooth iron, so that the swords would either break or glance off them, while he also had brass rims fitted to their shields, because the wood by itself could not endure a blow. He also instructed the soldiers to use long pikes, and to thrust them forward to receive the sword-cuts of the enemy. XLI. When the Gauls were encamped on the banks of the Anio, near the city, loaded with masses of plunder, Camillus led out his troops and posted them in a glen from which many valleys branched out, so that the greater part of the force was concealed, and that which was seen appeared to be clinging in terror to the hilly ground. Camillus, wishing to confirm the enemy in this idea, would not move to prevent the country being plundered before his eyes, but palisaded his camp and remained quiet within it, until he saw that the foraging parties of the Gauls straggled in careless disorder, while those in the camp did nothing but eat and drink. Then, sending forward his light troops before daybreak to be ready to harass the Gauls and prevent their forming their ranks properly as they came out of their camp, he marched the heavy-armed men down into the plain at sunrise, a numerous and confident body, and not, as the Gauls fancied, a few disheartened men. The very fact of his commencing the attack dashed the courage of the Gauls; next, the attacks of the light troops, before they had got into their wonted array and divided themselves into regiments, produced disorder. When at last Camillus led on the heavy-armed troops, the Gauls ran to meet them brandishing their swords, but the Romans with their pikes advanced and met them, receiving their sword-cuts on their armour, which soon made the Gaulish swords bend double, as they were made of soft iron hammered out thin, while the shields of the Gauls were pierced and weighed down by the pikes that stuck in them. They therefore dropped their own arms, and endeavoured to seize the pikes and turn them against their enemies. But the Romans, seeing them now defenceless, began to use their swords, and slew many of the first ranks, while the rest took to flight all over the flat country; for Camillus had taken care to guard the hills and rough ground, while the Gauls knew that they, in their over-confidence, had been at no pains to fortify their camp, and that the Romans could easily take it.
