The Romans were now at war with the Volscian nation, whose principal city was Corioli; when, therefore, Cominius the consul had invested this important place, the rest of the Volscians, fearing it would be taken, mustered up whatever force they could from all parts, to relieve it, designing to give the Romans battle before the city, and so attack them on both sides. Cominius, to avoid this inconvenience, divided his army, marching himself with one body to encounter the Volscians on their approach from without and leaving Titus Lartius, one of the bravest Romans of his time, to command the other and continue the siege. Those within Corioli, despising now the smallness of their number, made a sally upon them, and prevailed at first, and pursued the Romans into their trenches. Here it was that Marcius, flying out with a slender company, and cutting those in pieces that first engaged him, obliged the other assailants to slacken their speed; and then, with loud cries, called upon the Romans to renew the battle. For he had, what Cato thought a great point in a soldier, not only strength of hand and stroke, but also a voice and look that of themselves were a terror to an enemy. Divers of his own party now rallying and making up to him, the enemies soon retreated;but Marcius, not content to see them draw off and retire, pressed hard upon the rear, and drove them, as they fled away in haste, to the very gates of their city; where, perceiving the Romans to fall back from their pursuit, beaten off by the multitude of darts poured in upon them from the walls, and that none of his followers had the hardiness to think of falling in pell-mell among the fugitives and so entering a city full of enemies in arms, he, nevertheless, stood and urged them to the attempt, crying out, that fortune had now set open Corioli, not so much to shelter the vanquished, as to receive the conquerors. Seconded by a few that were willing to venture with him, he bore along through the crowd, made good his passage, and thrust himself into the gate through the midst of them, nobody at first daring to resist him. But when the citizens on looking about saw that a very small number had entered, they now took courage, and came up and attacked them. A combat ensued of the most extraordinary description, in which Marcius, by strength of hand, and swiftness of foot, and daring of soul, overpowering every one that he assailed, succeeded in driving the enemy to seek refuge, for the most part, in the interior of the town, while those remaining submitted, and threw down their arms; thus affording Lartius abundant opportunity to bring in the rest of the Romans with ease and safety.
Corioli being thus surprised and taken, the greater part of the soldiers employed themselves in spoiling and pillaging it, while Marcius indignantly reproached them, and exclaimed that it was a dishonourable and unworthy thing, when the consul and their Fellow-citizens had now perhaps encountered the other Volscians, and were hazarding their lives in battle, basely to misspend the time in running up and down for booty, and, under a pretence of enriching themselves, keep out of danger. Few paid him any attention, but, putting himself at the head of these, he took the road by which the consul's army had marched before him, encouraging his companions, and beseeching them, as they went along, not to give up, and praying often to the gods, too, that he might be so happy as to arrive before the fight was over, and come seasonably up to assist Cominius, and partake in the peril of the action.
It was customary with the Romans of that age, when they were moving into battle array, and were on the point of taking up their bucklers, and girding their coats about them, to make at the same time an unwritten will, or verbal testament, and to name who should be their heirs, in the hearing of three or four witnesses. In this precise posture Marcius found them at his arrival, the enemy being advanced within view.
They were not a little disturbed by his first appearance, seeing him covered with blood and sweat, and attended with a small train; but when he hastily made up to the consul with gladness in his looks, giving him his hand, and recounting to him how the city had been taken, and when they saw Cominius also embrace and salute him, every one took fresh heart; those that were near enough hearing, and those that were at a distance guessing, what had happened; and all cried out to be led to battle. First, however, Marcius desired to know of him how the Volscians had arrayed their army and where they had placed their best men and on his answering that he took the troops of the Antiates in the centre to be their prime warriors that would yield to none in bravery, "Let me demand and obtain of you," said Marcius, "that we may be posted against them." The consul granted the request, with much admiration for his gallantry. And when the conflict began by the soldiers darting at each other, and Marcius sallied out before the rest the Volscians opposed to him were not able to make head against him; wherever he fell in, he broke their ranks, and made a lane through them; but the parties turning again, and enclosing him on each side with their weapons, the consul, who observed the danger he was in despatched some of the choicest men he had for his rescue. The conflict then growing warm and sharp about Marcius and many falling dead in a little space, the Romans bore so hard upon their enemies, and pressed them with such violence, that they forced them at length to abandon their ground, and to quit the field. And going now to prosecute the victory, they besought Marcius, tired out with his toils, and faint and heavy through the loss of blood, that he would retire to the camp. He replied, however, that weariness was not for conquerors, and joined with them in the pursuit. The rest of the Volscian army was in like manner defeated, great numbers killed, and no less taken captive.
