When the Romans were now beginning to give ground in that quarter, Marcus Valerius, brother of Publicola, having observed young Tarquin boldly parading himself at the head of his exiles, fired besides with the renown of his house, that the family, which had gained glory by having expelled the kings, might also have the glory of destroying them, put spurs to his horse, and with his javelin couched made toward Tarquin. Tarquin retreated before his infuriated foe to a battalion of his own men. As Valerius rode rashly into the line of the exiles, one of them attacked him and ran him sideways through the body, and as the horse was in no way impeded by the wound of his rider, the Roman sank to the ground expiring, with his arms falling over his body. Postumius the dictator, seeing the fall of so distinguished a man, and that the exiles were advancing boldly at a run, and his own men disheartened and giving ground, gave the signal to his own cohort, a chosen body of men which he kept for the defence of his person, to treat every Roman soldier, whom they saw fleeing from the battle, as an enemy. Upon this the Romans, in fear of the danger on both sides, turned from flight and attacked the enemy, and the battle was restored. The dictator's cohort then for the first time engaged in the fight, and with persons and courage unimpaired, fell on the wearied exiles, and cut them to pieces. There another engagement took place between the leading officers. The Latin general, on seeing the cohort of the exiles almost surrounded by the Roman dictator, hurried up some companies of reserves to the front. Titus Herminius, a lieutenant-general, seeing them advancing in a body, and recognising Mamilius, distinguished among them by his armour and dress, encountered the leader of the enemy with violence so much greater than the master of the horse had shown a little before, that at one thrust he ran him through the side and slew him. While stripping the body of his enemy, he himself received a wound with a javelin, and, though brought back to the camp victorious, died while it was being dressed. Then the dictator hurried up to the cavalry, entreating them, as the infantry were tired out, to dismount and take up the fight. They obeyed his orders, dismounted, flew to the front, and, taking the place of the first line, covered themselves with their targets. The infantry immediately recovered their courage when they saw the young nobles sustaining a share of the danger with them, the mode of fighting being now the same for all. Then at length the Latins were beaten back, and their line, disheartened, gave way. The horses were then brought up to the cavalry, that they might pursue the enemy: the infantry likewise followed. Thereupon the dictator, disregarding nothing that held out hope of divine or human aid, is said to have vowed a temple to Castor, and to have promised rewards to the first and second of the soldiers who should enter the enemy's camp.
