In fact, it was this variance between the Samnites of the plain and the Samnites of the mountains that led the Romans over the Liris. The Sidicini in Teanum, and the Campanians in Capua, sought aid from the Romans (411) against their own countrymen, who in swarms ever renewed ravaged their territory and threatened to establish themselves there. When the desired alliance was refused, the Campanian envoys made offer of the submission of their country to the supremacy of Rome: and the Romans were unable to resist the bait.
Roman envoys were sent to the Samnites to inform them of the new acquisition, and to summon them to respect the territory of the friendly power. The further course of events can no longer be ascertained in detail;(20) we discover only that--whether after a campaign, or without the intervention of a war--Rome and Samnium came to an agreement, by which Capua was left at the disposal of the Romans, Teanum in the hands of the Samnites, and the upper Liris in those of the Volscians.
20. Perhaps no section of the Roman annals has been more disfigured than the narrative of the first Samnite-Latin war, as it stands or stood in Livy, Dionysius, and Appian. It runs somewhat to the following effect. After both consuls had marched into Campania in 411, first the consul Marcus Valerius Corvus gained a severe and bloody victory over the Samnites at Mount Gaurus; then his colleague Aulus Cornelius Cossus gained another, after he had been rescued from annihilation in a narrow pass by the self-devotion of a division led by the military tribune Publius Decius.
The third and decisive battle was fought by both consuls at the entrance of the Caudine Pass near Suessula; the Samnites were completely vanquished--forty thousand of their shields were picked up on the field of battle--and they were compelled to make a peace, in which the Romans retained Capua, which had given itself over to their possession, while they left Teanum to the Samnites (413). Congratulations came from all sides, even from Carthage. The Latins, who had refused their contingent and seemed to be arming against Rome, turned their arms not against Rome but against the Paeligni, while the Romans were occupied first with a military conspiracy of the garrison left behind in Campania (412), then with the capture of Privernum (413) and the war against the Antiates.
But now a sudden and singular change occurred in the position of parties. The Latins, who had demanded in vain Roman citizenship and a share in the consulate, rose against Rome in conjunction with the Sidicines, who had vainly offered to submit to the Romans and knew not how to save themselves from the Samnites, and with the Campanians, who were already tired of the Roman rule. Only the Laurentes in Latium and the -equites- of Campania adhered to the Romans, who on their part found support among the Paeligni and Samnites. The Latin army fell upon Samnium; the Romano-Samnite army, after it had marched to the Fucine lake and from thence, avoiding Latium, into Campania, fought the decisive battle against the combined Latins and Campanians at Vesuvius; the consul Titus Manlius Imperiosus, after he had himself restored the wavering discipline of the army by the execution of his own son who had slain a foe in opposition to orders from headquarters, and after his colleague Publius Decius Mus had appeased the gods by sacrificing his life, at length gained the victory by calling up the last reserves. But the war was only terminated by a second battle, in which the consul Manlius engaged the Latins and Campanians near Trifanum; Latium and Capua submitted, and were mulcted in a portion of their territory.
The judicious and candid reader will not fail to observe that this report swarms with all sorts of impossibilities. Such are the statement of the Antiates waging war after the surrender of 377 (Liv. vi. 33); the independent campaign of the Latins against the Paeligni, in distinct contradiction to the stipulations of the treaties between Rome and Latium; the unprecedented march of the Roman army through the Marsian and Samnite territory to Capua, while all Latium was in arms against Rome; to say nothing of the equally confused and sentimental account of the military insurrection of 412, and the story of its forced leader, the lame Titus Quinctius, the Roman Gotz von Berlichingen.
Still more suspicious perhaps, are the repetitions. Such is the story of the military tribune Publius Decius modelled on the courageous deed of Marcus Calpurnius Flamma, or whatever he was called, in the first Punic war; such is the recurrence of the conquest of Privernum by Gaius Plautius in the year 425, which second conquest alone is registered in the triumphal Fasti; such is the self-immolation of Publius Decius, repeated, as is well known, in the case of his son in 459. Throughout this section the whole representation betrays a different period and a different hand from the other more credible accounts of the annals. The narrative is full of detailed pictures of battles; of inwoven anecdotes, such as that of the praetor of Setia, who breaks his neck on the steps of the senate-house because he had been audacious enough to solicit the consulship, and the various anecdotes concocted out of the surname of Titus Manlius; and of prolix and in part suspicious archaeological digressions.
In this class we include the history of the legion--of which the notice, most probably apocryphal, in Liv. i. 52, regarding the maniples of Romans and Latins intermingled formed by the second Tarquin, is evidently a second fragment, the erroneous view given of the treaty between Capua and Rome (see my Rom. Munzwesen, p. 334, n. 122); the formularies of self-devotion, the Campanian -denarius-, the Laurentine alliance, and the -bina jugera- in the assignation (p. 450, note). Under such circumstances it appears a fact of great weight that Diodorus, who follows other and often older accounts, knows absolutely nothing of any of these events except the last battle at Trifanum; a battle in fact that ill accords with the rest of the narrative, which, in accordance with the rules of poetical justice, ought to have concluded with the death of Decius.
