23. While this battle was being fought near Antium, the Aequi had sent forward the flower of their troops, and by a surprise attack at night, had captured the Tusculan citadel. The rest of their army they stationed at a short distance from the walls of the town, in order to induce the enemy to extend his forces. [2] The news of these events being speedily carried to Rome and thence to the camp at Antium, had the same effect upon the Romans as if it had been announced that the Capitol was taken, — so fresh in their recollection was the service done them by the Tusculans, and so strongly did the similarity of the risk which their allies now ran seem to call for repayment of the assistance they had given. [3] Letting everything else go, Fabius quickly conveyed the plunder of the camp to Antium, and leaving there a moderate garrison, hastened by forced marches to Tusculum. The soldiers were allowed to take nothing but their arms and such bread as happened to be at hand;¹ supplies were sent them from Rome by the consul Cornelius. [4] The fighting at Tusculum lasted for some months. With a part of his army the consul laid siege to the camp of the Aequi; a part he had given to the Tusculans to use in recovering the citadel. [5] The place could [p. 81]never be entered by assault; but the enemy were² finally driven out by hunger. Having thus reduced them to extremities, the Tusculans took away their arms, and stripping them to the tunic, sent them under the yoke. As they were ignominiously fleeing homeward, the Roman consul overtook them on Mount Algidus, and slew them, every man. [6] The victor led his army back to Columen —this is the name of a place³ —and went into camp. The other consul too, now that the defeat of the enemy had removed all danger from the walls of Rome, set out himself from the City. [7] Thus at two points the consuls invaded the enemy's borders, and with keen rivalry devastated the lands of the Volsci on the one hand, and those of the Aequi on the other. I find in a good many writers that the Antiates revolted that same year; and that Lucius Cornelius the consul conducted the war and took the town. I should not venture to affirm it for a certainty, since there is no mention of the matter in the older historians.
