After the battle had gone in this way, so great a panic seized Tarquin and the Etruscans that the two armies of Veii and Tarquinii, on the approach of night, despairing of success, left the field and departed for their homes.
The story of the battle was enriched by marvels. In the silence of the next night a great voice is said to have come from the forest of Arsia, believed to be the voice of Silvanus, which spoke thus: “The fallen of the Tusci are one more than those of their foe; the Roman is conqueror.”
At all events the Romans left the field as victors; the Etruscans regarded themselves as vanquished, for when daylight appeared not a single enemy was in sight. P. Valerius, the consul, collected the spoils and returned in triumph to Rome.
