Agesipolis came to the crown just about the time that the confederacy (partly brought about by the intrigues of the Persian satrap Tithraustes), which was formed by Thebes, Athens, Corinth, and Argos, against Sparta, rendering it necessary to recall his colleague, Agesilaus II, from Asia; and the first military operation of his reign was the expedition to Corinth, where the forces of the confederates were assembled.
Having procured the sanction of the Olympic and Delphic gods for disregarding any attempt which the Argives might make to stop his march, on the pretext of a religious truce, he carried his ravages still farther than Agesilaus had done in 393; but as he suffered the aspect of the victims to deter him from occupying a permanent post, the expedition yielded no fruit but the plunder.
In this expedition the Spartans were assisted by Thebes, and in a battle with the Mantineans, the Theban generals Epaminondas and Pelopidas narrowly escaped death.
Agesipolis took the town by diverting the river Ophis, so as to put the low ground at the foot of the city walls under water.
[5][6][7][8][9] Early in 382, an embassy came to Sparta from the cities of Acanthus and Apollonia, requesting assistance against the Chalkidian League, who were endeavoring to compel them to join their confederacy.
