In fact, it was this variance between the Samnites of the plain and the Samnites of the mountains that led the Romans over the Liris. The Sidicini in Teanum, and the Campanians in Capua, sought aid from the Romans (411) against their own countrymen, who in swarms ever renewed ravaged their territory and threatened to establish themselves there. When the desired alliance was refused, the Campanian envoys made offer of the submission of their country to the supremacy of Rome: and the Romans were unable to resist the bait. Roman envoys were sent to the Samnites to inform them of the new acquisition, and to summon them to respect the territory of the friendly power. The further course of events can no longer be ascertained in detail[20]; we discover only that - whether after a campaign, or without the intervention of a war - Rome and Samnium came to an agreement, by which Capua was left at the disposal of the Romans, Teanum in the hands of the Samnites, and the upper Liris in those of the Volscians.
