Sallust Catilinae Coniuratio 45

Matters having proceeded thus far, and a night being appointed for the departure of the deputies, Cicero, being by them made acquainted with every thing, directed the prætors, ¹ Lucius Valerius Flaccus, and Caius Pomtinus, to arrest the retinue of the Allobroges, by laying in wait for them on the Milvian Bridge ; ² he gave them a full explanation of the object with which they were sent, ³ and left them to manage the rest as occasion might require. Being military men, they placed a force, as had been directed, without disturbance, and secretly invested the bridge; when the deputies, with Volturcius, came to the place, and a shout was raised from each side of the bridge, ⁴ the Gauls, at once comprehending the matter, surrendered themselves immediately to the prætors. Volturcius, at first, encouraging his companions, defended himself against numbers with his sword; but afterward, being unsupported by the Allobroges, he began earnestly to beg Pomtinus, to whom he was known, to save his life, and at last, terrified and despairing of safety, he surrendered himself to the prætors as unconditionally as to foreign enemies.
