Sulla left an able officer, Quintus Ofella, before Praeneste just as he had done in the previous year before Capua, with instructions not to expend his strength in the siege of the strong town, but to enclose it with an extended line of blockade and starve it into surrender.

He himself advanced from different sides upon the capital, which as well as the whole surrounding district he found abandoned by the enemy, and occupied without resistance.

He barely took time to compose the minds of the people by an address and to make the most necessary arrangements, and immediately passed on to Etruria, that in concert with Metellus he might dislodge his antagonists from Northern Italy.
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.
