History of the Peloponnesian War

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.

[On the other side], the Athenians were to seize on Delium, a place consecrated to Apollo in the territory of Tanagra, on the part toward Euboea. All this ought to have been done together upon a day appointed, to the end that the Boeotians might not oppose them with their forces united, but might be troubled every one to defend his own.
