On the news of Sulla's landing he went to Picenum, where he had extensive possessions and the best municipal connections derived from his father and the Social war, and set up the standard of the Optimate party in Auximum (Osimo).
The district, which was mostly inhabited by old burgesses, joined him; the young men, many of whom had served with him under his father, readily ranged themselves under the courageous leader who, not yet twenty-three years of age, was as much soldier as general, sprang to the front of his cavalry in combat, and vigorously assailed the enemy along with them.

The corps of Picenian volunteers soon grew to three legions; divisions under Cloelius, Gaius Carrinas, Lucius Junius Brutus Damasippus,( 13) were despatched from the capital to put down the Picenian insurrection, but the extemporized general, dexterously taking advantage of the dissensions that arose among them, had the skill to evade them or to beat them in detail and to effect his junction with the main army of Sulla, apparently in Apulia.

Sulla saluted him as -imperator-, that is, as an officer commanding in his own name and not subordinate but co-ordinate, and distinguished the youth by marks of honour such as he showed to none of his noble clients--presumably not without the collateral design of thereby administering an indirect rebuke to the lack of energetic character among his own partisans.

The main force of the enemy also proceeded thither, and it seemed as if the matter could not but there be brought to a decision.

The army of the consul Gaius Norbanus was already at Capua, where the new colony had just established itself with all democratic pomp; the second consular army was likewise advancing along the Appian road.
