History of the Peloponnesian War

When Alcibiades saw this, he dealt with Endius and the rest of the ephores again not to fear the voyage, alleging that they would [make haste, and] be there before the Chians should have heard of the misfortune of the fleet, and that as soon as he should arrive in Ionia himself, he could easily make the cities there to revolt by declaring unto them the weakness of the Athenians and the diligence of the Lacedaemonians, wherein he should be thought more worthy to be believed than any other.

Moreover to Endius he said that it would be an honour in particular to him that Ionia should revolt and the king be made confederate to the Lacedaemonians by his own means, and not to have it the mastery of Agis;

for he was at difference with Agis. So having prevailed with Endius and the other ephores, he took sea with five galleys, together with Chalcideus of Lacedaemon, and made haste.
