PARMENIO (c. 400-330 B.C.)  , Macedonian general in the service of Philip II. and Alexander the Great . During the reign of Philip Parmenio obtained a great victory over the Illyrians (356); he was one of the Macedonian delegates appointed to conclude peace with Athens (346), and was sent with an army to uphold Macedonian influence in Euboea (342) . In 336 he was sent with Amyntas and Attalus to make preparations for the reduction of Asia . He led the left wing in the battles of the Granicus, Issus and Gaugamela . After the conquest of Drangiana, Alexander was informed that Philotas, son of Parmenio, was involved in a conspiracy against his life . Philotas was condemned by the army and put to death . Alexander, thinking it dangerous to allow the father to live, sent orders to Media for the assassination of Parmenio . There was no proof that Parmenio was in any way implicated in the conspiracy, but he was not even afforded the opportunity of defending himself . See Arrian, Anabasis; Plutarch, Alexander; Diod . Sic. xvii.; Curtius vii .
