While the first months were passing, Antony was besieging Dec. Brutus in Mutina. All in those parts had now declared against Antony. Modena must at that time have been of very great extent, since Brutus with all his army lay in it. Antony however, who was very much superior to him in numbers, having nine or ten legions, could have starved him out; and he was going to compel him to surrender, when Hirtius and Pansa, and C. Octavius as prætor, came up with three armies to his relief. Hirtius and Octavius first posted themselves in the neighbourhood of Bologna, whither Pansa followed with reinforcements: Octavian only had veterans; the rest were newly raised legions inferior to those of Antony. The latter having marched against the enemy to prevent the junction with Pansa, the troops of Pansa and especially the _legio Martia_ which had been sent forward to his aid, heedlessly let themselves be drawn into a sort of irregular fight in which Antony at first had the worst of it, and then the better. When he was on the point of turning this advantage into a decided victory, Hirtius came up with reinforcements, and won the day. We have still extant an official bulletin of this battle, which was sent to Rome, and of which perhaps something must be abated. Pansa was severely wounded. As Antony did not stir from his lines, and the position of Dec. Brutus was by no means improved; the armies united, and ten or fourteen days afterwards Hirtius undertook an attack upon the camp of Antony: he broke through the upper lines, and took the camp; but he himself was killed in the battle. Dec. Brutus, however, had in the meanwhile made a furious sally, and joined the troops of the senate; so that Antony was obliged to give up the siege. He might still have kept his ground; but he entirely lost his head, and resolved upon leaving Italy.
