From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Metellus with the fleet went past Ariminum to Ravenna, and at Faventia cut off the communication between Ariminum and the valley of the Po, into which he sent forward a division along the great road to Placentia under Marcus Lucullus, the quaestor of Sulla and brother of his admiral in the Mithradatic war. The young Pompeius and his contemporary and rival Crassus penetrated from Picenum by mountain-paths into Umbria and gained the Flaminian road at Spoletium, where they defeated Carbo's legate Carrinas and shut him up in the town; he succeeded, however, in escaping from it on a rainy night and making his way, though not without loss, to the army of Carbo.
Sulla himself marched from Rome into Etruria with his army in two divisions, one of which advancing along the coast defeated the corps opposed to it at Saturnia (between the rivers Ombrone and Albegna); the second led by Sulla in person fell in with the army of Carbo in the valley of the Clanis, and sustained a successful conflict with his Spanish cavalry. But the pitched battle which was fought between Carbo and Sulla in the region of Chiusi, although it ended without being properly decisive, was so far at any rate in favour of Carbo that Sulla's victorious advance was checked.
