[1] [From the Peiresc manuscript] When the Roman generals Cornelius and Corvinus, and the plebeian Decius, had overcome the Samnites they left a military guard in Campania to ward off the Samnite incursions. These guards, partaking of the luxury and profuseness of the Campanians, were corrupted in their habits and began to envy the riches of these people, being themselves very poor and owing alarming debts in Rome. Finally they took counsel among themselves to kill their entertainers, seize their property, and marry their wives.

This infamy would perhaps have been carried out at once, had not the new general Mamercus, who was marching against the Samnites, learned the design of the Roman guard. Concealing his intentions, he disarmed some of them and dismissed them, as soldiers entitled to discharge for long service. The more villainous ones he ordered to Rome on the pretense of important business, and he sent with them a military tribune with orders to keep a secret watch over them. Both parties of soldiers suspected that their design had leaked out, and they broke away from the tribune near the town of Terracina. They set free all those who were working under sentence in the fields, armed them as well as they could, and marched to Rome to the number of about 20,000.

[2] [From the Peiresc manuscript] About one day's march from the city they were met by [dictator Marcus Valerius] Corvinus who went into camp near them on the Alban mount. He remained quietly in his camp while investigating what the matter was, and did not consider it wise to attack these desperadoes. The men mingled with each other privately, the guards acknowledging with groans and tears, as among relatives and friends, that they were to blame, but declaring that the cause of it all was the debts they owed at Rome. When Corvinus understood this he shrank from the responsibility of so much civil bloodshed and advised the Senate to release these men from debt. He exaggerated the difficulty of the war if it should be necessary to put down such a large body of men, who would fight with the energy of despair. He had strong suspicions also of the result of the meetings and conferences, lest his own army, who were relatives of these men and not less oppressed with debt, should be to some extent lacking in fidelity. If he should be defeated he said that the dangers would be greatly increased; if victorious, the victory itself would be most lamentable to the commonwealth, being gained over so many of their own relatives. The Senate was moved by his arguments and decreed a cancellation of debts to all Romans, and immunity also to these revolters. The latter laid down their arms and returned to the city.
