The peace with the Samnites lasted five years (464-469). Rome extended her frontiers, and fortified those of the peoples placed under her protectorate; and at the same time established new military forts.
The right of city without suffrage was accorded to the Sabines, and prefects were given to some of the towns of the valley of the Vulturnus (Venafrum and Allifæ).[208] A Latin colony, of twenty thousand men, was sent to Venusia to watch over Southern Italy.[209] It commanded at the same time Samnium, Apulia, and Lucania. If, owing to the treaty concluded with the Greek towns, the Roman supremacy extended over the south of the peninsula, to the north the Etruscans could not be reckoned as allies, since nothing more than truces had been concluded with them. In Umbria, the small tribe of the Sarsinates remained independent, and all the coast district from the Rubicon to the Æsis was in the power of the Senones; on their southern frontier the Roman colony of Sena Gallica (Sinigaglia) was founded; the coast of Picenum was watched by that of Castrum Novum and by the Latin fortress of Hatria (465).[210]
Third coalition of the Etruscans, Gauls, Lucanians, and Tarentines (469-474).
VIII. The power of Rome had increased considerably. The Samnites, who hitherto had played the first part, were no longer in a condition to plan further coalitions, and one people alone could hardly be rash enough to provoke the Republic. Yet the Lucanians, always hesitating, gave this time the signal for a general revolt.
The attack on Thurium, by the Lucanians and Bruttians, became the occasion of a new league, into which entered successively the Tarentines, the Samnites, the Etruscans, and even the Gauls. The north was soon in flames, and Etruria again became the battle-field. A Roman army, which had hastened to relieve Arretium, was put to rout by the Etruscans united with Gaulish mercenaries. The Senones, to whom these belonged, having massacred the Roman ambassadors sent to expostulate on their violation of the treaty with the Republic, the Senate sent against them two legions who drove them back beyond the Rubicon. The Gaulish tribe of the Boians, alarmed by the fate of the Senones, descended immediately into Umbria, and, rallying the Etruscans, prepared to march to renew the sack of Rome; but their march was arrested, and two successive victories, at Lake Vadimo, (471) and Populonia (472), enabled the Senate to conclude a convention which drove back the Boians into their old territory. Hostilities continued with the Etruscans during two years, after which their submission completed the conquest of Northern Italy.
Pyrrhus in Italy. Submission of Tarentum (474-488).
IX. Free to the north, the Romans turned their efforts against the south of Italy; war was declared against Tarentum, the people of which had attacked a Roman flotilla. While the consul Æmilius invested the town, the first troops of Pyrrhus, called in by the Tarentines, disembarked in the port (474).
This epoch marks a new phase in the destinies of Rome, who is going, for the first time, to measure herself with Greece. Hitherto the legions have never had to combat really regular armies, but they have become disciplined in war by incessant struggles in the mountains of Samnium and Etruria; henceforth they will have to face old soldiers disciplined in skilful tactics and commanded by an experienced warrior. The King of Epirus, after having already twice lost and recovered his kingdom, and invaded and abandoned Macedonia, dreamt of conquering the West. On the news of his arrival at the head of twenty-five thousand soldiers and twenty elephants,[211] the Romans enrolled all citizens capable of bearing arms, even the proletaries; but, admirable example of courage! they rejected the support of the Carthaginian fleet with this proud declaration: “The Republic only entertains wars which it can sustain with its own forces.”[212] While fifty thousand men, under the orders of the consul Lævinus, march against the King of Epirus, to prevent his junction with the Samnites, another army enters Lucania. The consul Tiberius Coruncanius holds Etruria, again in agitation. Lastly, an army of reserve guards the capital.
Lævinus encountered the King of Epirus near Heraclea, a colony of Tarentum (474). Seven times in succession the legions charged the phalanx, which was on the point of giving way, when the elephants, animals unknown to the Romans, decided the victory in favour of the enemy. A single battle had delivered to Pyrrhus all the south of the Peninsula, where the Greek towns received him with enthusiasm.
