History of the Peloponnesian War

For certain men in the cities thereabouts, desiring to change the form of the Boeotian government and to turn it into a democracy according to the government of Athens, practised with him and Hippocrates to betray unto him the estates of Boeotia, induced thereunto principally by Ptoeodorus, a Theban outlaw; and they ordered the design thus:

Some had undertaken to deliver up Siphae (Siphae is a city of the territory of Thespiae, standing upon the seaside in the Crissaean gulf); and Chaeroneia, which was a town that paid duties to Orchomenus (called heretofore Orchomenus in Minyeia, but now Orchomenus in Boeotia), some others of Orchomenus were to surrender into their hands. And the Orchomenian outlaws had a principal hand in this and were hiring soldiers to that end out of Peloponnesus. This Chaeroneia is the utmost town of Boeotia towards Phanotis in the country of Phocis; and some Phoceans also dwelt in it.
