Sertorius

Well, then, most of the Iberians immediately went away, sent ambassadors to Pompey and Metellus, and delivered themselves up to them; but those who remained Perpenna took under his command and attempted to do something. After using the materials provided by Sertorius just enough to cut a sorry figure and make it clear that he was fitted by nature neither to command nor to obey, he attacked Pompey;

and having been quickly crushed by him and taken prisoner, he did not even endure this extreme misfortune as a leader should, but, being in possession of the papers of Sertorius, he promised to show Pompey autograph letters from men of consular rank and of the highest influence in Rome, in which they invited Sertorius to come to Italy, assuring him that there were many there who desired eagerly to stir up a revolution and change the constitution.
