The Athenians themselves, as Ionians, went of their own free will against the Syracusans, who were Dorians, and with them went as members of the expedition the Lemnians, the Imbrians,cf. 4.28.4. The occupation of Lemnos was effected by Miltiades a few years after the battle of Marathon (Herod. VI. 137-140), that of Imbros probably about the same time; of Aegina in 431 B.C. (2.27.1); of Hestiaea in 446 B.C. (1.114.5). and the Aeginetans, who at this time held Aegina, as also the Hestiaeans who inhabit Hestiaea in Euboea, all these being colonists of the Athenians and having the same language and institutions as they had.
Of the rest, some took part in the expedition as subjects, others in consequence of an alliance, although independent, and some were mercenaries.
