Nectanebo II
Pharaoh Nectanebo II immediately enlisted the aid of the Greek mercenary, as he expected a Persian invasion was imminent. The pharaoh sent Mentor, at the head of 4000 mercenaries, to support Sidon, which had rebelled from Persia. Although Mentor won significant victories against some of the satraps, he was unable to defeat Artaxerxes' army, and was captured in 346 BC.
