History of the Peloponnesian War

Oropus being in their hands, the Eretrians now came to Rhodes to invite the Peloponnesians into Euboea. The latter, however, were rather bent on the relief of the distressed Chians, and accordingly put out to sea and sailed with all their ships from Rhodes.

Off Triopium they sighted the Athenian fleet out at sea sailing from Chalce, and neither attacking the other, arrived, the latter at Samos, the Peloponnesians at Miletus, seeing that it was no longer possible to relieve Chios without a battle. And this winter ended, and with it ended the twentieth year of this war of which Thucydides is the historian.

Early in the spring of the summer following Dercyllidas, a Spartan, was sent with a small force by land to the Hellespont: to effect the revolt of Abydos, which is a Milesian colony; and the Chians, while Astyochus was at a loss how to help them, were compelled to fight at sea by the pressure of the siege.
