Memnon of Rhodes
In 336 BC, Philip II sent Parmenion, with Amyntas, Andromenes and Attalus, and an army of 10,000 men into Asia Minor 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 assassinated and had been succeeded as king 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 the mercenary Memnon of Rhodes.
