From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
But neither that official negotiation nor this intrigue led to the desired result. When Metellus brought forward the suggestion that the king should give himself up in person as a prisoner, the latter broke off the negotiations; Bomilcar's intercourse with the enemy was discovered, and he was arrested and executed. These diplomatic cabals of the meanest kind admit of no apology; but the Romans had every reason to aim at the possession of the person of their antagonist.
The war had reached a point, at which it could neither be carried farther nor abandoned. The state of feeling in Numidia was evinced by the revolt of Vaga,(13) the most considerable of the cities occupied by the Romans, in the winter of 646-7; on which occasion the whole Roman garrison, officers and men, were put to death with the exception of the commandant Titus Turpilius Silanus, who was afterwards--whether rightly or wrongly, we cannot tell--condemned to death by a Roman court-martial and executed for having an understanding with the enemy.
