Memnon of Rhodes
When Mentor died in c. 340 BC, Memnon married his widow Barsine. In 339 BC, Memnon helped to defend Byzantium against an assault by Philip II. In 336 BC Philip II sent Parmenion, with Amyntas, Andromenes and Attalus, and an army of 10,000 men into Anatolia to make preparations for an invasion to free the Greeks living on the western coast and islands from Achaemenid rule. At first, all went well. The Greek cities on the western coast of Anatolia revolted until the news arrived that Philip had been murdered and had been succeeded by his young son Alexander. The Macedonians were demoralized by Philip's death and were subsequently defeated near Magnesia by the Achaemenids under the command of Memnon of Rhodes.
