From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
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.
