There Arpinum and Frusino became subject, the latter town was deprived of a third of its domain, and on the upper Liris in addition to Fregellae the Volscian town of Sora, which had previously been garrisoned, was now permanently converted into a Roman fortress and occupied by a legion of 4000 men.

In this way the old Volscian territory was completely subdued, and became rapidly Romanized.

The region which separated Samnium from Etruria was penetrated by two military roads, both of which were secured by new fortresses.

The northern road, which afterwards became the Flaminian, covered the line of the Tiber; it led through Ocriculum, which was in alliance with Rome, to Narnia, the name which the Romans gave to the old Umbrian fortress Nequinum when they settled a military colony there (455).

The southern, afterwards the Valerian, ran along the Fucine lake by way of the just mentioned fortresses of Carsioli and Alba.
