History of the Peloponnesian War

This news of Chios was quickly brought to the Athenians, who, conceiving themselves to be now beset with great and evident danger, and that the rest of the confederates, seeing so great a city to revolt, would be no longer quiet, in this their present fear decreed that those thousand talents, which through all this war they had affected to keep untouched, forthwith abrogating the punishment ordained for such as spake or gave their suffrages to stir it, should now be used, and therewith galleys not a few manned. They decreed also to send thither out of hand, under the command of Strombichides, the son of Diotimus, eight galleys of the number of those that besieged the enemy at Peiraeus; the which, having forsaken their charge to give chase to the galleys that went with Chalcideus, and not able to overtake them, were now returned; and shortly after also to send Thrasycles to help them with twelve galleys more, which also had departed from the same guard upon the enemy.

And those seven galleys of Chios, which likewise kept watch at Peiraeus with the rest, they fetched from thence, and gave the bondmen that served in them their liberty, and the chains to those that were free. And instead of all those galleys that kept guard upon the galleys of the Peloponnesians, they made ready other with all speed in their places, besides thirty more, which they intended to furnish out afterwards. Great was their diligence; and nothing was of light importance that they went about for the recovery of Chios.
