Perpenna attacked these cohorts, and was engaged in their pursuit, when Pompey appeared in force, joined battle, and won a complete victory. Most of Perpenna’s officers perished in the battle, but Perpenna himself was brought before Pompey, who ordered him to be put to death. In this he did not show ingratitude, nor that he was unmindful of what had happened in Sicily, Cf. chapter x. 2 , where there is nothing to imply that Perpenna put Pompey under any obligations to him, except that he made no resistance. as some allege against him, but exercised great forethought and salutary judgement for the commonwealth. For Perpenna, who had come into possession of the papers of Sertorius, offered to produce letters from the chief men at Rome, who had desired to subvert the existing order and change the form of government, and had therefore invited Sertorius into Italy. Pompey, therefore, fearing that this might stir up greater wars than those now ended, put Perpenna to death and burned the letters without even reading them.
