Similar conflicts probably raged in the north around Firmum, Atria, Pinna, in the south around Luceria, Beneventum, Nola, Paestum, before and while the Roman armies gathered on the borders of the insurgent country.

After the southern army under Caesar had assembled in the spring of 664 in Campania which for the most part held by Rome, and had provided Capua--with its domain so important for the Roman finances--as well as the more important allied cities with garrisons, it attempted to assume the offensive and to come to the aid of the smaller divisions sent on before it to Samnium and Lucania under Marcus Marcellus and Publius Crassus.

But Caesar was repulsed by the Samnites and Marsians under Publius Vettius Scato with severe loss, and the important town of Venafrum thereupon passed over to the insurgents, into whose hands it delivered its Roman garrison.

By the defection of this town, which lay on the military road from Campania to Samnium, Aesernia was isolated, and that fortress already vigorously assailed found itself now exclusively dependent on the courage and perseverance of its defenders and their commandant Marcellus.

It is true that an incursion, which Sulla happily carried out with the same artful audacity as formerly his expedition to Bocchus, relieved the hard-pressed Aesernians for a moment; nevertheless they were after an obstinate resistance compelled by the extremity of famine to capitulate towards the end of the year.
In Lucania too Publius Crassus was defeated by Marcus Lamponius, and compelled to shut himself up in Grumentum, which fell after a long and obstinate siege.
