History of the Peloponnesian War

About the same time the Peloponnesians in the twenty-five ships stationed opposite to the squadron at Naupactus to protect the passage of the transports to Sicily, had got ready for engaging, and manning some additional vessels, so as to be numerically little inferior to the Athenians, anchored off Erineus in Achaia in the Rhypic country.

The place off which they lay being in the form of a crescent, the land forces furnished by the Corinthians and their allies on the spot, came up and ranged themselves upon the projecting headlands on either side, while the fleet, under the command of Polyanthes, a Corinthian, held the intervening space and blocked up the entrance.
