Metellus against Carbo in Northern Italy - Carbo Assailed on Three Sides of Etruria
Metellus had meanwhile encountered and defeated Carbo's lieutenant Carrinas at the river Aesis (Esino between Ancona and Sinigaglia), which separated the district of Picenum from the Gallic province; when Carbo in person came up with his superior army, Metellus had been obliged to abstain from any farther advance. But on the news of the battle at Sacriportus, Carbo, anxious about his communications, had retreated to the Flaminian road, with a view to take up his headquarters at the meeting-point of Ariminum, and from that point to hold the passes of the Apennines on the one hand and the valley of the Po on the other.
In this retrograde movement different divisions fell into the hands of the enemy, and not only so, but Sena Gallica was stormed and Carbo's rearguard was broken in a brilliant cavalry engagement by Pompeius; nevertheless Carbo attained on the whole his object. The consular Norbanus took the command in the valley of the Po; Carbo himself proceeded to Etruria. But the march of Sulla with his victorious legions to Etruria altered the position of affairs; soon three Sullan armies from Gaul, Umbria, and Rome established communications with each other.
