26. Immediately afterwards a fresh alarm was created at Rome by the Sabines, but it was more a sudden raid than a regular war. News was brought during the night that a Sabine army had advanced as far as the Anio on a predatory expedition, and that the farms in that neighbourhood were being harried and burnt. [2] A. Postumius, who had been the Dictator in the Latin war, was at once sent there with the whole of the cavalry force; the consul Servilius followed with a picked body of infantry. [3] Most of the enemy were surrounded by the cavalry while scattered in the fields; the Sabine legion offered no resistance to the advance of the infantry. Tired out with their march and the nocturnal plundering-a large proportion of them were in the farms full of food and wine —they had hardly sufficient strength to flee.

[4] The Sabine war was announced and concluded in one night, and strong hopes were entertained that peace had now been secured everywhere. The next day, however, envoys from the Auruncans came with a demand for the evacuation of the Volscian territory, otherwise they were to proclaim war. [5] The army of the Auruncans had begun their advance when the envoys left home, and the report of its having been seen not far from Aricia created so much excitement and confusion amongst the Romans that it was impossible either for the senate to take the matter into formal consideration, or for a favourable reply to be given to those who were commencing hostilities, since they were themselves taking up arms to repel them. [6] They marched to Aricia; not far from there they engaged the Auruncans and in one battle finished the war.
