However, it was not long before the party of the rebels recovered from their defeats. Agesilaues either joined them, or withdrew from the struggle, and removing to Cyrene died there at an advanced age. Tacho, deserted by his followers, quitted Egypt and fled to Sidon, whence he made his way across the desert to the court of the Great King. Ochus, who had by this time succeeded Mnemon, received him favourably, and professed an intention of embracing his cause; but nothing came of this expression of good-will. Tacho lived a considerable time at the court of Ochus, without any steps being taken to restore him to his former position. At last a dysentery carried him off, and legitimated the position of the usurper who had driven him into exile.
The end now drew nigh. Nekht-nebf, whom the Greeks called Nectanebo II., having after a time established himself firmly upon the throne, and got rid of pretenders, resumed the ambitious policy of his predecessor, and entered into an alliance with the people of Sidon and their neighbours, who were in revolt against Persia. He had the excuse that Ochus, some time previously, had sent an expedition against Egypt, which he had repulsed by the assistance of two Greek generals, Diophantus of Athens and Lamius of Sparta. But this expedition was a thing of the past; it had inflicted no injury on Egypt, and it demanded no revenge. Nekht-nebf was in no way called upon to join the rebel confederacy, which (in B.C. 346) raised the flag of revolt from Persia, and sought to enrol in its ranks as many allies as possible. But he rashly gave in his name, and sent to Sidon as his contingent towards the army that was being raised, four thousand of his Greek mercenaries, under the command of Mentor of Rhodes. With their aid, Tennes, the Sidonian king, completely defeated the troops which Ochus had sent against him, and drove the Persians out of Phoenicia.
The success, however, which was thus gained by the rebels only exasperated the Persian king, and made him resolve all the more on a desperate effort. The time had gone by, he felt, for committing wars to satraps, or sending out generals, with a few thousand troops, to put down this or that troublesome chieftain. The conjuncture called for measures of no ordinary character. The Great King must conduct an expedition in person. Every sort of preparation must be made; arms and provisions and stores of all kinds must be accumulated; the best troops must be collected from all parts of the empire; a sufficient fleet must be manned; and such an armament must go forth under the royal banner as would crush all opposition. Ochus succeeded in gathering together from the nations under his direct rule 300,000 foot, 30,000 horse, 300 triremes, and 500 transports or provision-ships. He then directed his efforts towards obtaining efficient assistance from the Greeks. Though refused aid by Athens and Sparta, he succeeded in obtaining a thousand Theban heavy-armed under Lacrates, three thousand Argives
