In the very beginning of the next winter, when the Boeotian cities should have been delivered to Hippocrates and Demosthenes, generals of the Athenians, and Demosthenes should have gone to Siphae, and Hippocrates to Delium; having mistaken the days on which they should have both set forward, Demosthenes went to Siphae first, and having with him the Acarnans and many confederates of those parts in his fleet, [yet] lost his labour. For the treason was detected by one Nicomachus, a Phocean of the town of Phanotis, who told it unto the Lacedaemonians, and they again unto the Boeotians.

Whereby the Boeotians, concurring universally to relieve those places (for Hippocrates was not yet gone to trouble them in their own several territories), preoccupied both Siphae and Chaeroneia. And the conspirators, knowing the error, attempted in those cities no further.
