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.

Immediately after the affair at Plataea, Lacedaemon sent round orders to the cities in Peloponnese and the rest of her confederacy to prepare troops and the provisions requisite for a foreign campaign, in order to invade Attica.

The several states were ready at the time appointed and assembled at the Isthmus; the contingent of each city being two-thirds of its whole force.
