In the year 428 the war began within the Samnite land itself: some towns on the Campanian frontier, Rufrae (between Venafrum and Teanum) and Allifae, were occupied by the Romans.

In the following years the Roman armies penetrated Samnium, fighting and pillaging, as far as the territory of the Vestini, and even as far as Apulia, where they were received with open arms; everywhere they had very decidedly the advantage.
The courage of the Samnites was broken; they sent back the Roman prisoners, and along with them the dead body of the leader of the war party, Brutulus Papius, who had anticipated the Roman executioners, when the Samnite national assembly determined to ask the enemy for peace and to procure for themselves more tolerable terms by the surrender of their bravest general.

But when the humble, almost suppliant, request was not listened to by the Roman people (432), the Samnites, under their new general Gavius Pontius, prepared for the utmost and most desperate resistance.

The Roman army, which under the two consuls of the following year (433) Spurius Postumius and Titus Veturius was encamped near Calatia (between Caserta and Maddaloni), received accounts, confirmed by the affirmation of numerous captives, that the Samnites had closely invested Luceria, and that that important town, on which depended the possession of Apulia, was in great danger.

They broke up in haste.
