Viriathus stands as the most successful leader who ever opposed the Roman conquest in Iberia. During the course of his campaigns he was only defeated in battle against the Romans once, and from a military standpoint can be said to have been one of the most successful generals to have ever opposed Rome's expansion. Ultimately, even the Romans recognized that it was more prudent to use treachery rather than open confrontation to defeat the Lusitanian uprising. Some fifty years later, the renegade Roman general Quintus Sertorius, at the head of another insurrection in Iberia, would meet a similar fate.
