The victory of Rome was complete; and she turned it to full account. It was not from magnanimity in the conquerors - for the Romans knew nothing of the sort - but from shrewd and far-seeing calculation that terms so moderate were granted to the Samnites, the Tarentines, and the more distant peoples generally. The first and main object was not so much to compel southern Italy as quickly as possible to recognize formally the Roman supremacy, as to supplement and complete the subjugation of central Italy, for which the way had been prepared by the military roads and fortresses already established in Campania and Apulia during the last war, and by that means to separate the northern and southern Italians into two masses cut off in a military point of view from direct contact with each other. To this object accordingly the next undertakings of the Romans were with consistent energy directed.  Above all they used, or made, the opportunity for getting rid of the confederacies of the Aequi and the Hernici which had once been rivals of the Roman single power in the region of the Tiber and were not yet quite set aside. In the same year, in which the peace with Samnium took place (450), the consul Publius Sempronius Sophus waged war on the Aequi; forty townships surrendered in fifty days; the whole territory with the exception of the narrow and rugged mountain valley, which still in the present day bears the old name of the people (Cicolano), passed into the possession of the Romans, and here on the northern border of the Fucine lake was founded the fortress Alba with a garrison of 6000 men, thenceforth forming a bulwark against the valiant Marsi and a curb for central Italy; as was also two years afterwards on the upper Turano, nearer to Rome, Carsioli - both as allied communities with Latin rights.

The fact that in the case of the Hernici at least Anagnia had taken part in the last stage of the Samnite war, furnished the desired reason for dissolving the old relation of alliance. The fate of the Anagnines was, as might be expected, far harder than that which had under similar circumstances been meted out to the Latin communities in the previous generation. They not merely had, like these, to acquiesce in the Roman citizenship without suffrage, but they also like the Caerites lost self-administration; out of a portion of their territory on the upper Trerus (Sacco), moreover, a new tribe was instituted, and another was formed at the same time on the lower Anio (455). The only regret was that the three Hernican communities next in importance to Anagnia, Aletrium, Verulae, and Ferentinum, had not also revolted; for, as they courteously declined the suggestion that they should voluntarily enter into the bond of Roman citizenship and there existed no pretext for compelling them to do so, the Romans were obliged not only to respect their autonomy, but also to allow to them even the right of assembly and of intermarriage, and in this way still to leave a shadow of the old Hernican confederacy. No such considerations fettered their action in that portion of the Volscian country which had hitherto been held by the Samnites. 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. 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].

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. The Celts in northern Italy were just beginning to bestir themselves again after a long suspension of warfare; moreover several Etruscan communities there were still in arms against the Romans, and brief armistices alternated in that quarter with vehement but indecisive conflicts. All central Italy was still in ferment and partly in open insurrection; the fortresses were still only in course of construction; the way between Etruria and Samnium was not yet completely closed. Perhaps it was not yet too late to save freedom; but, if so, there must be no delay; the difficulty of attack increased, the power of the assailants diminished with every year by which the peace was prolonged.  Five years had scarce elapsed since the contest ended, and all the wounds must still have been bleeding which the twenty-two years' war had inflicted on the peasantry of Samnium, when in the year 456 the Samnite confederacy renewed the struggle. The last war had been decided in favour of Rome mainly through the alliance of Lucania with the Romans and the consequent standing aloof of Tarentum. The Samnites, profiting by that lesson, now threw themselves in the first instance with all their might on the Lucanians, and succeeded in bringing their party in that quarter to the helm of affairs, and in concluding an alliance between Samnium and Lucania. Of course the Romans immediately declared war; the Samnites had expected no other issue. It is a significant indication of the state of feeling, that the Samnite government informed the Roman envoys that it was not able to guarantee their inviolability, if they should set foot on Samnite ground.

The war thus began anew (456), and while a second army was fighting in Etruria, the main Roman army traversed Samnium and compelled the Lucanians to make peace and send hostages to Rome. The following year both consuls were able to proceed to Samnium; Rullianus conquered at Tifernum, his faithful comrade in arms, Publius Decius Mus, at Maleventum, and for five months two Roman armies encamped in the land of the enemy. They were enabled to do so, because the Tuscan states had on their own behalf entered into negotiations for peace with Rome. The Samnites, who from the beginning could not but see that their only chance of victory lay in the combination of all Italy against Rome, exerted themselves to the utmost to prevent the threatened separate peace between Etruria and Rome; and when at last their general, Gellius Egnatius, offered to bring aid to the Etruscans in their own country, the Etruscan federal council in reality agreed to hold out and once more to appeal to the decision of arms. Samnium made the most energetic efforts to place three armies simultaneously in the field, the first destined for the defence of its own territory, the second for an invasion of Campania, the third and most numerous for Etruria; and in the year 458 the last, led by Egnatius himself, actually reached Etruria in safety through the Marsian and Umbrian territories, with whose inhabitants there was an understanding.
