History of the Peloponnesian War

A party was to betray to them Siphae, a seaport town in the Thespian territory, on the Crisaean Bay; while Chaeronea, which was dependent on what was formerly called the Minyan, but now the Boeotian Orchomenus, was to be delivered up by another party in that city; the exiles from it also co-operating most warmly, and raising mercenary troops from the Peloponnese. Chaeronea is the frontier town too of Boeotia, near to Phanotis in Phocis, and a party of Phocians joined in the design. On the other hand, the Athenians were to seize Delium, the sanctuary of Apollo in the territory of Tanagra, looking towards Euboea;

and these measures were to be simultaneously executed on the same day; that the Boeotians might not oppose them in a body at Delium, but have to attend to their own respective neighbourhoods that were being revolutionized.
