History of the Peloponnesian War

That of Athens comprised the Chians, Lesbians, Plateans, the Messenians in Naupactus, most of the Acarnanians, the Corcyraeans, Zacynthians, and some tributary cities in the following countries, viz., Caria upon the sea with her Dorian neighbors, Ionia, the Hellespont, the Thracian towns, the islands lying between Peloponnese and Crete towards the east, and all the Cyclades except Melos and Thera.

Of these, ships were furnished by Chios, Lesbos, and Corcyra, infantry and money by the rest.

Such were the allies of either party and their resources for the war.
