Some writers assert that it was not against the Apulians that the campaign was undertaken, but for the protection of their allies against the wanton aggressions of the Samnites The circumstances of that people, however, who were hardly able to defend themselves, make it more probable that they had not attacked the Apulians but that both nations were united in hostilities against Rome.
Nothing noteworthy took place; the districts of both Samnium and Apulia were laid waste, but neither in the one nor the other was the enemy met with. At Rome the citizens were one night suddenly aroused from sleep by an alarm so serious that the Capitol, the Citadel, the walls, and gates were filled with troops.
The whole population was called to arms, but when it grew light neither the author nor the cause of the excitement was discovered.
