Thus the convention of Caudium did not produce the rest which the enthusiasts for peace in Samnium had foolishly expected from it, but only led to war after war with exasperation aggravated on either side by the opportunity forfeited, by the breach of a solemn engagement, by military honour disgraced, and by comrades that had been abandoned. The Roman officers given up were not received by the Samnites, partly because they were too magnanimous to wreak their vengeance on those unfortunates, partly because they would thereby have admitted the Roman plea that the agreement bound only those who swore to it, not the Roman state. Magnanimously they spared even the hostages whose lives had been forfeited by the rules of war, and preferred to resort at once to arms.

Luceria was occupied by them and Fregellae surprised and taken by assault (434) before the Romans had reorganized their broken army; the passing of the Satricans[2] over to the Samnites shows what they might have accomplished, had they not allowed their advantage to slip through their hands. But Rome was only momentarily paralyzed, not weakened; full of shame and indignation the Romans raised all the men and means they could, and placed the highly experienced Lucius Papirius Cursor, equally distinguished as a soldier and as a general, at the head of the newly formed army. The army divided; the one-half marched by Sabina and the Adriatic coast to appear before Luceria, the other proceeded to the same destination through Samnium itself, successfully engaging and driving before it the Samnite army. They formed a junction again under the walls of Luceria, the siege of which was prosecuted with the greater zeal, because the Roman equites lay in captivity there; the Apulians, particularly the Arpani, lent the Romans important assistance in the siege, especially by procuring supplies. After the Samnites had given battle for the relief of the town and been defeated, Luceria surrendered to the Romans (435). Papirius enjoyed the double satisfaction of liberating his comrades who had been given up for lost, and of requiting the yoke of Caudium on the Samnite garrison of Luceria. In the next years (435-437) the war was carried on[3] not so much in Samnium itself as in the adjoining districts. In the first place the Romans chastised the allies of the Samnites in the Apulian and Frentanian territories, and concluded new conventions with the Teanenses of Apulia and the Canusini. At the same time Satricum was again reduced to subjection and severely punished for its revolt. Then the war turned to Campania, where the Romans conquered the frontier town towards Samnium, Saticula (perhaps S. Agata de' Goti) (438). But now the fortune of war seemed disposed once more to turn against them. The Samnites gained over the Nucerians (438), and soon afterwards the Nolans, to their side; on the upper Liris the Sorani of themselves expelled the Roman garrison (439); the Ausonians were preparing to rise, and threatened the important Cales; even in Capua the party opposed to Rome was vigorously stirring. A Samnite army advanced into Campania and encamped before the city, in the hope that its vicinity might place the national party in the ascendant (440). But Sora was immediately attacked by the Romans and recaptured after the defeat of a Samnite relieving force (440). The movements among the Ausonians were suppressed with cruel rigour ere the insurrection fairly broke out, and at the same time a special dictator was nominated to institute and decide political processes against the leaders of the Samnite party in Capua, so that the most illustrious of them died a voluntary death to escape from the Roman executioner (440). The Samnite army before Capua was defeated and compelled to retreat from Campania; the Romans, following close at the heels of the enemy, crossed the Matese and encamped in the winter of 440 before Bovianum, the capital of Samnium. Nola was abandoned by its allies; and the Romans had the sagacity to detach the town for ever from the Samnite party by a very favourable convention, similar to that concluded with Neapolis (441). Fregellae, which after the catastrophe of Caudium had fallen into the hands of the party adverse to Rome and had been their chief stronghold in the district on the Liris, finally fell in the eighth year after its occupation by the Samnites (441); two hundred of the citizens, the chief members of the national party, were conveyed to Rome, and there openly beheaded in the Forum as an example and a warning to the patriots who were everywhere bestirring themselves.

Apulia and Campania were thus in the hands of the Romans. In order finally to secure and permanently to command the conquered territory, several new fortresses were founded in it during the years 440-442: Luceria in Apulia, to which on account of its isolated and exposed situation half a legion was sent as a permanent garrison; Pontiae (the Ponza islands) for the securing of the Campanian waters; Saticula on the Campano-Samnite frontier, as a bulwark against Samnium; and lastly Interamna (near Monte Cassino) and Suessa Aurunca (Sessa) on the road from Rome to Capua. Garrisons moreover were sent to Caiatia (Cajazzo), Sora, and other stations of military importance. The great military road from Rome to Capua, which with the necessary embankment for it across the Pomptine marshes the censor Appius Claudius caused to be constructed in 442, completed the securing of Campania. The designs of the Romans were more and more fully developed; their object was the subjugation of Italy, which was enveloped more closely from year to year in a network of Roman fortresses and roads.  The Samnites were already on both sides surrounded by the Roman meshes; already the line from Rome to Luceria severed north and south Italy from each other, as the fortresses of Norba and Signia had formerly severed the Volsci and Aequi; and Rome now rested on the Arpani, as it formerly rested on the Hernici. The Italians could not but see that the freedom of all of them was gone if Samnium succumbed, and that it was high time at length to hasten with all their might to the help of the brave mountain people which had now for fifteen years singly sustained the unequal struggle with the Romans.

The most natural allies of the Samnites would have been the Tarentines; but it was part of that fatality that hung over Samnium and over Italy in general, that at this moment so fraught with the destinies of the future the decision lay in the hands of these Athenians of Italy. Since the constitution of Tarentum, which was originally after the old Doric fashion strictly aristocratic, had become changed to a complete democracy, a life of singular activity had sprung up in that city, which was inhabited chiefly by mariners, fishermen, and artisans. The sentiments and conduct of the population, more wealthy than noble, discarded all earnestness amidst the giddy bustle and witty brilliance of their daily life, and oscillated between the grandest boldness of enterprise and elevation of spirit on the one hand, and a shameful frivolity and childish whim on the other. It may not be out of place, in connection with a crisis wherein the existence or destruction of nations of noble gifts and ancient renown was at stake, to mention that Plato, who came to Tarentum some sixty years before this time, according to his own statement saw the whole city drunk at the Dionysia, and that the burlesque farce, or "merry tragedy" as it was called, was created in Tarentum about the very time of the great Samnite war. This licentious life and buffoon poetry of the Tarentine fashionables and literati had a fitting counterpart in the inconstant, arrogant, and short-sighted policy of the Tarentine demagogues, who regularly meddled in matters with which they had nothing to do, and kept aloof where their immediate interests called for action. After the Caudine catastrophe, when the Romans and Samnites stood opposed in Apulia, they had sent envoys thither to enjoin both parties to lay down their arms (434). This diplomatic intervention in the decisive struggle of the Italians could not rationally have any other meaning than that of an announcement that Tarentum had at length resolved to abandon the neutrality which it had hitherto maintained. It had in fact sufficient reason to do so.  It was no doubt a difficult and dangerous thing for Tarentum to be entangled in such a war; for the democratic development of the state had directed its energies entirely to the fleet, and while that fleet, resting upon the strong commercial marine of Tarentum, held the first rank among the maritime powers of Magna Graecia, the land force, on which they were in the present case dependent, consisted mainly of hired soldiers and was sadly disorganized. Under these circumstances it was no light undertaking for the Tarentine republic to take part in the conflict between Rome and Samnium, even apart from the - at least troublesome - feud in which Roman policy had contrived to involve them with the Lucanians.  But these obstacles might be surmounted by an energetic will; and both the contending parties construed the summons of the Tarentine envoys that they should desist from the strife as meant in earnest. The Samnites, as the weaker, showed themselves ready to comply with it; the Romans replied by hoisting the signal for battle. Reason and honour dictated to the Tarentines the propriety of now following up the haughty injunction of their envoys by a declaration of war against Rome; but in Tarentum neither reason nor honour characterized the government, and they had simply been trifling in a very childish fashion with very serious matters. No declaration of war against Rome took place; in its stead they preferred to support the oligarchical party in the Sicilian towns against Agathocles of Syracuse who had at a former period been in the Tarentine service and had been dismissed in disgrace, and following the example of Sparta, they sent a fleet to the island - a fleet which would have rendered better service in the Campanian seas (440).
