If these measures cost Tachus his popularity, they empowered him to raise 24,000 native soldiers and 10,000 Greeks to equip a fleet of two hundred sail and to hire the best generals of the period. But he was too emulative to succeed, he was not contented with Chabrias and the alliance with Athens, but he also wanted Agesilaus and the alliance of Sparta. In spite of his infirmities and his eighty years, Agesilaus was not insensible to gain and flattery; and tempted by the promise of supreme command, he set out with a thousand soldiers. On his arrival he was met by a disappointment, for Tachus only gave him the command of the mercenaries, as he kept the chief leadership for himself and put the fleet in the hands of Chabrias.
The old hero, after showing his vexation by an exhibition of Spartan temper, was appeased by the presents he was given, and he consented to accept the proffered post. However, disputes of a more serious character soon broke out between him and his allies, for he wished Tachus to remain in Egypt, and leave the conduct of the operations to his generals. But the facility with which the captains of the troops passed from one camp to another was not calculated to inspire the Egyptian with confidence, so he refused, and after nominating his brother-in-law, who also bore the name of Tachus, regent, he repaired to the camp. The Persians were not strong enough to appear in the open, so Tachus commanded his cousin Nekht-neb-ef (Nectanebo II), the son of the regent, to besiege them in their fortresses. The war then dragged along and discontent broke out among the troops, and treachery lurked in the army. The financial expedient of Chabrias had exasperated the priests and the common people, and the complaints which had been stifled by fear of the mercenaries, were voiced as soon as the expedition had crossed the frontier. The regent, instead of quelling this discontent, secretly fomented it, and wrote to tell his son to claim the crown.
Nectanebo soon won over to his side the Egyptians under his command, but they were insufficient so long as the Greeks had not declared for him. Chabrias refused to withdraw from his engagements with the king; but Agesilaus was not so scrupulous. His vanity had been deeply wounded whilst in Egypt, for not only had he been refused the command to which he considered he was entitled, but his small figure, his infirmities and his rough Lacedæmonian ways had been made fun of by the courtiers. When Tachus begged Agesilaus to take the field against the rebels, he ironically replied that he had been sent to help the Egyptians, not to fight against them. However, before finally deciding which side to take, he consulted the ephores, and, as they permitted him to do his best to advance the interests of the country, he declared himself for Nectanebo, in spite of the entreaties of Chabrias.
Tachus, thus abandoned by his allies, took refuge at Sidon, and from thence he repaired to Artaxerxes, who received him kindly and placed him at the head of a fresh expedition against Egypt in the year 361.
The news of the king’s application to Persia excited general revolt in the valley of the Nile, and as the support of the foreigner aroused the suspicion of the native races, they joined the prince of Mendes.
Nectanebo having abandoned the conquests of his predecessors brought back his forces to Egypt, and arrived at Pelusium, where he found himself at the head of a large and resolute army with which, albeit undisciplined, Agesilaus advised the king to attack the insurgents before they had time to take the field. But unfortunately the Spartan was not in favour, for the prince of Mendes had tried to corrupt him, and although he had on that occasion shown unhoped-for loyalty, he was not trusted. Nectanebo made Tanis his headquarters, and his enemies hoped to besiege him there. The circle of ditches encompassing the town was almost completed, and provisions were getting scarce, when Agesilaus received orders to attempt a sortie, but he forced the blockade under shadow of the night, and a few days later, gained a decisive victory.
Nectanebo would gladly have kept him with him, for he was in fear of a surprise by the Persians, but the Spartan, being tired of Egypt and her intrigues, left the country, and died of exhaustion on the coast of Cyrenaica [probably 360].
The onset soon followed, as Pharaoh had anticipated, but it was weak and uncertain: Tachus, who was to have led it, died before it began, and the discords of the royal family prevented the other generals from acting in concert. The old Artaxerxes had three sons by his wife Statira—Darius, Ariaspes, and Ochus. Darius the eldest had been solemnly recognised as heir presumptive, but threatened with seeing himself supplanted by Ochus, he conspired the death of his father; however, he was discovered, imprisoned, and executed in his cell. So Ariaspes became the successor-elect, but Ochus told him that his father intended to have him put to an ignominious death, and he persuaded him to commit suicide so as to escape it. Arsames, a bastard son of one of the harem ladies, still remained as an heir to the throne, but he was assassinated by Ochus, and Artaxerxes succumbed to this last misfortune and died of sorrow, after a reign of forty-six years [358].
