The defection of a part of the Apulians, in 431, encouraged the Samnites to take arms again; defeated in the following years, they asked for the restoration of friendly relations, but the haughty refusal of Rome led, in 433, to the famous defeat of the Furcæ Caudinæ. The generosity of the Samnite general, Pontus Herennius, who granted their lives to so many thousands of prisoners on condition of restoring to force the old treaties, had no effect upon the Senate. Four legions had passed under the yoke--a circumstance in which the Senate only saw a new affront to revenge. The treaty of Caudium was not ratified, and subterfuges little excusable, although approved at a later period by Cicero,[192] gave to the refusal an appearance of justice. Meanwhile the Senate exerted itself vigorously to repair this check, and soon Publilius Philo defeated the enemies in Samnium, and, in Apulia, Papirius, in his turn, caused seven thousand Samnites to pass under the yoke. The vanquished solicited peace, but in vain; they only obtained a truce for two years (436), and it had hardly expired, when, penetrating into the country of the Volsci, as far as the neighbourhood of Terracina, and taking a position at Lautulæ, they defeated a Roman army raised hastily and commanded by Q. Fabius (439). Capua deserted, and Nola, Nuceria, the Aurunci, and the Volsci of the Liris took part openly with the Samnites. The spirit of rebellion spread as far as Præneste. Rome was in danger. The Senate required its utmost energy to restrain populations whose fidelity was always doubtful. Fortune seconded its efforts, and the allies, who had proved traitors, received a cruel chastisement, explained by the terror they had inspired. In 440,[193] not far from Caudium, a numerous army encountered the Samnites, who lost 30,000 men, and were driven back into the Apennine territory. The Roman legions proceeded to encamp before their capital, Bovianum, and there took up their winter quarters. The year following (441), Rome, less occupied in fighting, profited by this circumstance to seize upon advantageous positions, establishing in Campania and Apulia colonies which surrounded the territory of Samnium. At the same epoch, Appius Claudius transformed into a regular causeway the road which has preserved his name.[194] The Romans turned their attention to the defence of the coasts and communication by sea; a colony was sent to the isle of Pontia,[195] opposite Tarracina, and the armament of a fleet was commenced, which was placed under the command of _duumviri navales_.[196] The war had lasted fifteen years, and, although Rome had only succeeded in driving back the Samnites into their own territory, she had conquered two provinces, Apulia and Campania.
