To meet the invader the great king had in Asia Minor an army slightly larger, it would seem, than Alexander's, gathered under the satraps of the western provinces at Zeleia.
The great provinces were divided into many smaller districts, the governors of which are also called satraps and hyparchs.
The satraps likewise made overtures to Sparta.
Effecting his escape from Nora, he raised an army, and formed a coalition with the satraps of the eastern provinces.
Mentor after the conquest of Egypt rose high in the favour of the king, and Memnon, who had taken refuge with Artabazus at the Macedonian court, became a zealous adherent of the Persian king; he assisted Mentor in subduing the rebellious satraps and dynasts in Asia Minor, and succeeded him as general of the Persian troops.
