History of the Peloponnesian War

The Peloponnesians and the rest, who were at the same time in the twenty-five galleys that for safeguard of the ships lay opposite to the galleys before Naupactus, having prepared themselves for battle, and with more galleys, so as they were little inferior in number to those of the Athenians, went to an anchor under Irineus of Achaia in Rhypica. The place where they rode was in form like a half moon;

and their land forces they had ready on either side to assist them, both Corinthians and their other confederates of those parts, embattled upon the points of the promontory; and their galleys made up the space between, under the command of Polyanthes, a Corinthian.
