History of the Peloponnesian War

Afterwards, when the fleet had rounded the promontory, it took up these men, abandoned Pheia, and put out to sea, for meanwhile the main body of the Eleans had come to the rescue. The Athenians now resumed their voyage along the coast, and visiting other places made depredations.

About this same time the Athenians sent out thirty ships to operate around Locris and at the same time to serve as a guard for Euboea.

These were under the command of Cleopompus son of Clinias, who made descents upon various places along the seaboard and ravaged them, captured Thronium, some of whose inhabitants he took as hostages, and at Alope defeated in battle the Locrians who came to the defence of the town.
