History of the Peloponnesian War

The Athenians themselves being Ionians went against the Dorians of Syracuse of their own free will; and the peoples still speaking Attic and using the Athenian laws, the Lemnians, Imbrians, and Aeginetans, that is to say, the then occupants of Aegina, being their colonists, went with them. To these must be also added the Hestiaeans dwelling at Hestiaea in Euboea.

Of the rest some joined in the expedition as subjects of the Athenians, others as independent allies, others as mercenaries.

To the number of the subjects paying tribute belonged the Eretrians, Chalcidians, Styrians, and Carystians from Euboea; the Ceans, Andrians, and Tenians from the islands; and the Milesians, Samians, and Chians from Ionia. The Chians, however, joined as independent allies, paying no tribute, but furnishing ships. Most of these were Ionians and descended from the Athenians, except the Carystians, who are Dryopes, and although subjects and obliged to serve, were still Ionians fighting against Dorians.

Besides these there were men of Aeolic race, the Methymnians, subjects who provided ships, not tribute, and the Tenedians and Aenians who paid tribute. These Aeolians fought against their Aeolian founders, the Boeotians in the Syracusan army, because they were obliged, while the Plataeans, the only native Boeotians opposed to Boeotians, did so upon a just quarrel.
