When this was known to Publius Vellæus who commanded the nearest army, he sent some allied cavalry and light infantry to attack those who were roaming in quest of plunder or of reinforcements, while he marched in person with the main strength of the foot to raise the siege. Every operation was at the same moment successful; the pillagers were cut to pieces; dissensions broke out among the besiegers, and the king made a well-timed sally just as the legion arrived. A battle or even a skirmish it did not deserve to be called, in which merely half-armed stragglers were slaughtered without bloodshed on our side.
