History of the Peloponnesian War

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.

For Agis, as long as he was about Deceleia with the power he had, had the law in his own hands to send what army and whither he listed and to levy men and money at his pleasure. And at this time, the confederates of him (as I may call them) did better obey him than the confederates of the Lacedaemonians did them at home; for having the power in his hands, he was terrible wheresoever he came. And he was now for the Lesbians.
