History of the Peloponnesian War

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.

While Astyochus was still at Rhodes they had received from Miletus, as their commander after the death of Pedaritus, a Spartan named Leon, who had come out with Antisthenes, and twelve vessels which had been on guard at Miletus, five of which were Thurian, four Syracusan, one from Anaia, one Milesian, and one Leon's own.

Accordingly the Chians marched out in mass and took up a strong position, while thirty-six of their ships put out and engaged thirty-two of the Athenians; and after a tough fight, in which the Chians and their allies had rather the best of it, as it was now late, retired to their city.
