History of the Peloponnesian War

But the confederates of either party, which they had when they began it, were these.

The Lacedaemonians had all Peloponnesus within the isthmus except the Argives and Achaeans (for these were in amity with both, save that the Pellenians at first, only of all Achaia, took their part; but afterwards all the rest did so likewise); and without Peloponnesus, the Megareans, Locrians, Boeotians, Phoceans, Ambraciotes, Leucadians, and Anactorians. Of which the Corinthians, Megareans, Sicyonians, Pellenians, Eleians, Ambraciotes, and Leucadians found shipping;

the Boeotians, Phoceans, and Locrians, horsemen; and the rest of the cities, footmen. And these were the confederates of the Lacedaemonians. The Athenian confederates were these:

the Chians, Lesbians, Plataeans, the Messenians in Naupactus, most of the Acarnanians, Corcyraeans, Zacynthians, and other cities their tributaries among those nations; also that part of Caria which is on the seacoast and the Dorians adjoining to them; Ionia, Hellespont, the cities bordering on Thrace; all the islands from Peloponnesus to Crete on the east and all the rest of the Cyclades except Melos and Thera.

Of these the Chians, Lesbians, and Corcyraeans found galleys; the rest, footmen and money.
