History of the Peloponnesian War

Here they persuaded their allies the Metapontines, to send with them three hundred darters and two galleys, and with this reinforcement coasted on to Thurii, where they found the party hostile to Athens recently expelled by a revolution,

and accordingly remained there to muster and review the whole army, to see if any had been left behind, and to prevail upon the Thurians resolutely to join them in their expedition, and in the circumstances in which they found themselves to conclude a defensive and offensive alliance with the Athenians.

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.

The Athenians under Diphilus now sailed out against them with thirty-three ships from Naupactus,

and the Corinthians, at first not moving, at length thought they saw their opportunity, raised the signal, and advanced and engaged the Athenians.
