Antonius marched by the Via Flaminia, and arrived at Saxa Rubra, when the night was far spent, too late to give any help. There he received nothing but gloomy intelligence, that Sabinus was dead, that the Capitol had been burnt to the ground, that Rome was in consternation, and also that the populace and the slaves were arming themselves for Vitellius. And Petilius Cerialis had been defeated in a cavalry skirmish. While he was hurrying on without caution, as against a vanquished enemy, the Vitellianists, who had disposed some infantry among their cavalry, met him. The conflict took place not far from the city among buildings, gardens, and winding lanes, which were well known to the Vitellianists, but disconcerting to their opponents, to whom they were strange. Nor indeed were all the cavalry one in heart, for there were with them some who had lately capitulated at Narnia, and who were anxiously watching the fortunes of the rival parties. Tullius Flavianus, commanding a squadron, was taken prisoner; the rest fled in disgraceful confusion, but the victors did not continue the pursuit beyond Fidenæ.
