12. The deliberation of the senate was short. They all, to a man, concurred in opinion, that a compact should be entered into with the Lucanians, and satisfaction demanded from the Samnites: accordingly, a favourable answer was returned to the Lucanians, and the alliance concluded. [2] Heralds were then sent, to require of the Samnites, that they should depart from the country of the allies, and withdraw their troops from the Lucanian territory. These were met by persons despatched for the purpose by the Samnites, who gave them warning, that “if they appeared at any assembly in Samnium, they must not expect to depart in safety.” [3] As soon as this was heard at Rome, the senate voted, and the people ordered, that war should be declared against the Samnites. The consuls, then, dividing the provinces between them, Etruria fell to Scipio, the Samnites to Fulvius; and they set out by different routes, each against the enemy allotted to him. [4] Scipio, while he expected a tedious campaign, like that of the preceding year, was met near Volaterra by the Etrurians, in order of battle. [5] The fight lasted through the greater part of the day, while very many fell on both sides, and night came on while it was uncertain to which side victory inclined. But the following dawn showed the conqueror and the vanquished; for the Etrurians had decamped in the dead of the night. [6] The Romans, marching out with intent to renew the engagement, and seeing their superiority acknowledged by the departure of the enemy, advanced to their camp; and, finding even this fortified post deserted, took possession of it, evacuated as it was, together with a vast quantity of spoil. [7] The consul then, leading back his forces into the Faliscian territory, and leaving his baggage with a small guard at Falerii, set out with his troops, lightly accoutred, to ravage the enemy's country. [8] All places are destroyed with fire and sword; plunder driven from every side; and not only was the ground left a mere waste to the enemy, but their forts and small towns were set on fire; he refrained from attacking the cities into which fear had driven the Etrurians. The consul Cneius Fulvius fought a glorious battle in Samnium, near Bovianum, attended with success by no means equivocal. [9] Then, having attacked Bovianum, and not long after Aufidena, he took them by storm. [p. 643]This year a colony was carried out to Carseoli, into the territory of the $Aequicolae. The consul Fulvius triumphed on his defeat of the Samnites.
