History of the Peloponnesian War

When Alcibiades knew this, he again persuaded Endius and the rest of the ephors not to shrink from the expedition; telling them that they would have made their voyage before the Chians heard of the disaster which had befallen their fleet; and that he himself, when he had once reached Ionia, would easily persuade the cities to revolt, by acquainting them both with the weakness of the Athenians and the forwardness of the Lacedaemonians; for he should be thought more credible than others.

To Endius himself he also represented in private, that it would be a glorious thing to have caused by his own agency the revolt of Ionia, and to have brought the king into alliance with the Lacedaemonians, instead of that honour being earned by Agis; (for with him he happened to be at variance.)

He, then, having prevailed on the rest of the ephors, as well as Endius, put out to sea with the five ships, in company with Chalcideus the Lacedaemonian, and they proceeded on their voyage with all speed.
