The Hernici became aware of what was going on and warned the Romans that Ecetra had revolted to the Aequi. The colonists of Antium were also suspected, because on the capture of that town a large number of the inhabitants had taken refuge with the Aequi, and they were the most efficient soldiers throughout the war.
When the Aequi were driven into their walled towns, this body was broken up and returned to Antium.
There they found the colonists already disaffected, and they succeeded in completely alienating them from Rome. Before matters were ripe, information was laid before the senate that a revolt was in preparation, and the consuls were instructed to summon the chiefs of the colony to Rome and question them as to what was going on.
They came without any hesitation, but after being introduced by the consuls to the senate, they gave such unsatisfactory replies that heavier suspicion attached to them on their departure than on their arrival.
War was certain. Sp. Furius, the consul to whom the conduct of the war had been assigned, marched against the Aequi and found them committing depredations in the territory of the Hernici. Ignorant of their strength, because they were nowhere all in view at once, he rashly joined battle with inferior forces.
At the first onset he was defeated, and retired into his camp, but he was not out of danger there. For that night and the next day the camp was surrounded and attacked with such vigour that not even a messenger could be despatched to Rome.
