Ochus, besides his 330,000 Asiatics, had now a force of 14,000 Greeks--6000 furnished by the Greek cities of Asia Minor; 4000 under Mentor, consisting of the troops which he had brought to the aid of Tennes from Egypt; 3000 sent by Argos; and 1000 from Thebes.

He divided his numerous armament into three bodies, and placed at the head of each two generals--one Persian and one Greek.

The Greek commanders were Lacrates of Thebes, Mentor of Rhodes, and Nicostratus of Argos, a man of enormous strength, who regarded himself as a second Hercules, and adopted the traditional costume of that hero--a club and a lion's skin.
The Persians were Rhossaces, Aristazanes, and Bagoas, the chief of the eunuchs.

Nectanebo was only able to oppose to this vast array an army less than one third of the size.

Twenty thousand, however, out of the 100,000 troops at his disposal were Greeks; he occupied the Nile and its various branches with a numerous navy the character of the country, intersected by numerous canals, and full of strongly fortified towns, was in his favor; and he might have been expected to make a prolonged, if not even a successful, resistance.
