Pelopidas (6.1-6.2)

But when the Lacedaemonians deprived Phoebidas of his command and fined him a hundred thousand drachmas, and yet held the Cadmeia with a garrison notwithstanding, all the rest of the Greeks were amazed at their inconsistency, since they punished the wrong-doer, but approved his deed. And as for the Thebans, they had lost their ancestral form of government and were enslaved by Archias and Leontidas, nor had they hopes of any deliverance from this tyranny,

which they saw was guarded by the dominant military power of the Spartans and could not be pulled down unless those Spartans should somehow be deposed from their command of land and sea. Nevertheless, Leontidas and his associates, learning that the fugitive Thebans were living at Athens, where they were not only in favour with the common people but also honoured by the nobility, secretly plotted against their lives, and sending men who were unknown, they treacherously killed Androcleides, but failed in their designs upon the rest.
