History of the Peloponnesian War

While Astyochus was there, the ambassadors of the Lesbians came unto him, desiring to revolt from the Athenians. And as for him, they prevailed with him; but seeing the Corinthians and the other confederates were unwilling in respect of their former ill success there, he put to sea for Chios. Whither, after a great tempest, his galleys, some from one place and some from another, at length arrived all.

After this, Pedaritus, who was now at Erythrae, whither he was come from Miletus by land, came over with his forces into Chios. Besides those forces he brought over with him, he had the soldiers which were of the five galleys that came thither with Chalcideus and were left there, to the number of five hundred, and armour to arm them.

Now some of the Lesbians having promised to revolt, Astyochus communicated the matter with Pedaritus and the Chians, alleging how meet it would be to go with a fleet and make Lesbos to revolt, for that they should either get more confederates, or failing, they should at least weaken the Athenians. But they gave him no ear; and for the Chian galleys, Pedaritus told him [plainly] he should have none of them.
