History of the Peloponnesian War

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.
