History of the Peloponnesian War

And this number on both sides, against Sicily and for it, some to help win and some to help save it, came to the war at Syracuse, not on any pretence of right nor as kindred to aid kindred, but as profit or necessity severally chanced to induce them. The Athenians, being Ionic, went against the Syracusians, that be Doric, voluntarily.

With these, as being their colonies, went the Lemnians and Imbrians, and the Aeginetae that dwelt in Aegina then, all of the same language and institutions with themselves; also the Hestiaeans of Euboea. Of the rest, some went with them as their subjects and some as their free confederates and some also hired.

Subjects and tributaries: as the Eretrians, Chalcideans, Styrians, and Carystians, from Euboea; Ceians, Andrians, Tenians, from out of the islands; Milesians, Samians, and Chians, from Ionia.

Of these the Chians followed them as free, not as tributaries of money, but of galleys. And these were almost all of them Ionians, descended from the Athenians, except only the Carystians, that are of the nation of the Dryopes. And though they were subjects and went upon constraint, yet they were Ionians against Dorians. Besides these there went with them Aeolians, namely, the Methymnaeans, subjects to Athens, not tributaries of money but of galleys; and the Tenedians and Aenians, tributaries. Now here, Aeolians were constrained to fight against Aeolians, namely, against their founders the Boeotians, that took part with the Syracusians.
