Mithrenes
Mithrenes was a Persian commander of the force that garrisoned the citadel of Sardis. According to Cyril Toumanoff, he was also a member of the Orontid dynasty, of Iranian origin. Waldemar Heckel, on the other hand, considers Mithrenes to be a Persian noble of unknown family background. After the battle of the Granicus Mithrenes surrendered voluntarily to Alexander the Great, and was treated by him with great distinction. Mithrenes was present in the Macedonian camp after the Battle of Issus, and Alexander ordered him to visit the captured family of Darius III and assure them that Darius was alive, before changing his mind and assigning the duty to Leonnatus instead. He fought for Alexander at Gaugamela, and ironically he was fighting against an army that included his father Orontes II. Afterwards, Alexander appointed him Satrap of Armenia.
