The small tribes within whose bounds these colonies were instituted, the Umbrians who obstinately defended Nequinum, the Aequians who once more assailed Alba, and the Marsians who attacked Carsioli, could not arrest the course of Rome: the two strong curb-fortresses were inserted almost without hindrance between Samnium and Etruria.

We have already mentioned the great roads and fortresses instituted for permanently securing Apulia and above all Campania: by their means Samnium was further surrounded on the east and west with the net of Roman strongholds.

It is a significant token of the comparative weakness of Etruria that it was not deemed necessary to secure the passes through the Ciminian Forest in a similar mode--by a highway and corresponding fortresses.

The former frontier fortress of Sutrium continued to be in this quarter the terminus of the Roman military line, and the Romans contented themselves with having the road leading thence to Arretium kept in a serviceable state for military purposes by the communities through whose territories it passed.( 4) Renewed Outbreak of the Samnite-Etruscan War-- Junction of the Troops of the Coalition in Etruria The high-spirited Samnite nation perceived that such a peace was more ruinous than the most destructive war; and, what was more, it acted accordingly.
