History of the Peloponnesian War

The Lacedaemonians also issued to the states a requisition for building a hundred ships, fixing their own quota and that of the Boeotians at five and twenty each; that of the Phocians and Locrians together at fifteen; that of the Corinthians at fifteen; that of the Arcadians, Pellenians, and Sicyonians, at ten; and that of the Megareans, Troezenians, Epidaurians, and Hermionians at ten. They were also making all other preparations, with the intention of proceeding immediately to war at the very commencement of spring.

The Athenians too, as they had determined, were preparing during this same winter for building ships; having contributed towards the supply of timbers, and fortified Sunium, that their corn-ships might have a safe passage round; while they also evacuated the fort in Laconia, which they had built in that country when they were sailing by it for Sicily; and with a view to economy retrenched all their other expenses, whatever any where appeared to be useless expenditure; and, above all, kept their eye on the allies, to prevent their revolting from them.

While both parties were carrying out these measures, and engaged in preparation for the war, just as when they were commencing it, the Euboeans, first of all, sent during this winter an embassy to Agis, to treat of their revolting from the Athenians. He acceded to their proposals, and sent for Alcamenes son of Sthenelaidas, and for Melanthus, to come from Sparta and take the command in Euboea. Accordingly they came with about three hundred of the Neodamodes, and he began to prepare for their crossing over.

But in the mean time some Lesbians also came to him; for they, too, wished to revolt. And as the Boeotians supported their application, Agis was persuaded to defer acting in the cause of Euboea, and made preparations for the revolt of the Lesbians, giving them Alcamenes as a commander, who was to sail to Euboea; while the Boeotians promised them ten ships, and Agis the same number.
