Thebes.—Conspiracy of Leontiades and the philo-Laconian party in Thebes, to betray the town and citadel to Phœbidas.—The opposing leaders—Leontiades and Ismenias—were both Polemarchs.—Leontiades overawes the Senate, and arrests Ismenias: Pelopidas and the leading friends of Ismenias go into exile.—Phœbidas in the Kadmeia—terror and submission at Thebes.—Mixed feelings at Sparta—great importance of the acquisition to Spartan interests.—Displeasure at Sparta more pretended than real, against Phœbidas; Agesilaus defends him.—Leontiades at Sparta—his humble protestations and assurances—the ephors decide that they will retain the Kadmeia, but at the same time fine Phœbidas.—The Lacedæmonians cause Ismenias to be tried and put to death. Iniquity of this proceeding.—Vigorous action of the Spartans against Olynthus—Teleutias is sent there with a large force, including a considerable Theban contingent. Derdas coöperates with him.—Teleutias being at first successful, and having become over-confident, sustains a terrible defeat from the Olynthians under the walls of their city.—Agesipolis is sent to Olynthus from Sparta with a reinforcement. He dies of a fever.—Polybiades succeeds Agesipolis as commander—he reduces Olynthus to submission—extinction of the Olynthian federation. Olynthus and the other cities are enrolled as allies of Sparta.—Intervention of Sparta with the government of Phlius.—Agesilaus marches an army against Phlius—reduces the town by blockade, after a long resistance. The Lacedæmonians occupy the acropolis, naming a council of one hundred as governors. 1-72 CHAPTER LXXVII.
