History of the Peloponnesian War

When the wind came down, the enemy's ships were now in a narrow space, and what with the wind and the small craft dashing against them, at once fell into confusion: ship fell foul of ship, while the crews were pushing them off with poles, and by their shouting, swearing and struggling with one another, made captains' orders and boatswains' cries alike inaudible, and through being unable for want of practice to clear their oars in the rough water, prevented the vessels from obeying their helmsmen properly. At this moment Phormio gave the signal, and the Athenians attacked. Sinking first one of the admirals, they then disabled all they came across, so that no one thought of resistance for the confusion, but fled for Patrae and Dyme in Achaea.

The Athenians gave chase and captured twelve ships, and taking most of the men out of them sailed to Molycrium, and after setting up a trophy on the promontory of Rhium and dedicating a ship to Poseidon, returned to Naupactus.

As for the Peloponnesians, they at once sailed with their remaining ships along the coast from Dyme and Patrae to Cyllene, the Eleian arsenal; where Cnemus and the ships from Leucas that were to have joined them, also arrived after the battle of Stratus.
