Commencement of the War - The Fortresses - Caesar in Campania and Samnium - Aesernia Taken by the Insurgents - As also Nola - Campania for the Most Part Lost to the Romans
The first assault, as a matter of course, fell on the fortresses adhering to Rome in the insurgent districts, which in all haste closed their gates and carried in their moveable property from the country. Silo threw himself on the fortress designed to hold in check the Marsians, the strong Alba, Mutilus on the Latin town of Aesernia established in the heart of Samnium: in both cases they encountered the most resolute resistance. 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.
