Among the cavalry in Caesar's camp were two brothers, Allobrogians by birth, named Roscillus and Aegus, the sons of Adbucillus, who had long held the chief sway in his own state; men of singular bravery, and who had been of signal service to Caesar in all his Gallic wars. For these reasons he had raised them to the highest offices in their own country, got them chosen into the senate before they were of age, given them lands in Gaul taken from the enemy, besides pecuniary rewards to a great value, insomuch that from very moderate beginnings they had risen to vast wealth. These men were not only highly honoured by Caesar on account of their bravery, but in great esteem with the whole army. But presuming on Caesar's friendship, and foolishly elated with their prosperity, they used the troopers ill, defrauded them of their pay, and secreted all the plunder to their own use. The Gaulish cavalry, offended at these proceedings, went in a body to Caesar, and openly complained of the two brothers; adding, among other accusations, that, by giving in false musters, they received pay for more men than they had.
