History of the Peloponnesian War

And the Lacedaemonians imposed upon the states confederate, the charge of building one hundred galleys; that is to say, on their own state and on the Boeotians, each twenty-five; on the Phoceans and Locrians, fifteen; on the Corinthians, fifteen; on the Arcadians, Sicyonians, and Pellenians, ten; and on the Megareans, Troezenians, and Hermionians, ten. And put all things else in readiness presently with the spring to begin the war.

The Athenians also made their preparations as they had designed, having gotten timber and built their navy this same winter, and fortified the promontory of Sunium that their cornboats might come about in safety. Also they abandoned the fort in Laconia, which they had built as they went by for Sicily. And generally where there appeared expense upon anything unuseful, they contracted their charge.

Whilst they were on both sides doing thus, there came unto Agis about their revolt from the Athenians, first the ambassadors of the Euboeans. Accepting the motion, he sent for Alcamenes, the son of Sthenelaidas, and for Melanthus from Lacedaemon to go commanders into Euboea. Whom, when he was come to him with about three hundred freedmen, he was now about to send over. But in the meantime came the Lesbians, they also desiring to revolt;

and by the means of the Boeotians Agis changed his former resolution and prepared for the revolt of Lesbos, deferring that of Euboea, and assigned them Alcamenes, the same that should have gone into Euboea, for their governor; and the Boeotians promised them ten galleys and Agis other ten. Now this was done without acquainting therewith the state of Lacedaemon.
