43. Matters were conducted with the same success by the other consul at Cominium: leading up his forces to the walls, at the first dawn, he invested the city on every side, and posted strong guards opposite to the gates to prevent any sally being made. [2] Just as he was giving the signal, the alarming message from his colleague, touching the march of the twenty Samnite cohorts, not only caused him to delay the assault, but obliged him to call off a part of his troops, when they were formed and ready to begin the attack. [3] He ordered Decius Brutus Scaeva, a lieutenant-general, with the first legion, ten auxiliary cohorts, and the cavalry, to go and oppose the said detachment; [4] and in whatever place he should meet the foe, there to stop and detain them, and even to engage in battle, should opportunity offer for it; at all events not to suffer those troops to approach Cominium. [5] He then commanded the scaling ladders to be brought up to the walls, on every side of the city; and, under a fence of closed shields, advanced to the gates. Thus, at the same moment, the gates were broken open, and the assault made on every part of the walls. [6] Though the Samnites, before they saw the assailants on the works, had possessed courage enough to oppose their approaches to the city, yet now, when the action was no longer carried on at a distance, nor with missile weapons, but in close fight; and when those, who had with difficulty gained the walls, having overcome the disadvantage of ground, which [p. 688]they principally dreaded, fought with ease on equal ground, against an enemy inferior in strength, they all forsook the towers and [7??] walls, and being driven to the forum, they tried there for a short time, as a last effort, to retrieve the fortune of the fight; [8] but soon throwing down their arms, surrendered to the consul, to the number of eleven thousand four hundred; four thousand three hundred and eighty were slain. [9] Such was the course of events at Cominium, such at Aquilonia. In the middle space between the two cities, where a third battle had been expected, the enemy were not found; for, when they were within seven miles of Cominium, they were recalled by their countrymen, and had no part in either battle. [10] At night-fall, when they were now within sight of their camp, and also of Aquilonia, shouts from both places reaching them with equal force induced them to halt; [11] then, on the side of the camp, which had been set on fire by the Romans, the wide-spreading flames indicating with more certainty the disaster [which had happened], prevented their proceeding any farther. [12] In that same spot, stretched on the ground at random under their arms, they passed the whole night in great inquietude, at one time wishing for, at another dreading the light. [13] At the first dawn, while they were still undetermined to what quarter they should direct their march, they were obliged to betake themselves hastily to flight, being descried by the cavalry; who having gone in pursuit of the Samnites, that left the town in the night, saw the multitude unprotected either by a rampart or advanced guard. [14] This party had likewise been perceived from the walls of Aquilonia, and the legionary cohorts now joined in the pursuit. The foot were unable to overtake them, but about two hundred and eighty of their rear guard were cut off by the cavalry. [15] In their consternation they left behind them a great quantity of arms and eighteen military standards: they reached Bovianum with the rest of their party in safety, as far as could be expected after so disorderly a rout.
