In this quarter, then, the Peloponnesians were victorious and had disabled the Athenian ships; but the twenty ships covering their right wing were pursuing the eleven Athenian ships which had got past them as they swung round and had escaped into the open water. And all the eleven except one reached Naupactus ahead of them, and riding at anchor off the Temple of Apollo, prows outward, made ready to defend themselves if the enemy put in toward the shore to attack them.
When the Peloponnesians came up they were singing the paean as they rowed as if they were victorious already, and one Leucadian ship, far ahead of the rest, was chasing the single Athenian ship which lagged behind.
But, as it chanced, a merchantman was lying at anchor in deep water and this the Athenian ship succeeded in reaching first and, sailing round it, rammed the pursuing Leucadian vessel amidships and sank her.
At this unexpected and amazing feat consternation fell upon the Peloponnesians, who were, moreover, pursuing in disorder because they had the upper hand; on some of their ships the rowers sank their oars into the water and checked the headway of their vessels, intending to await the main body of their fleet- a serious mistake to make in the face of an enemy lying near and ready for the chargewhile others, unfamiliar with the waters there, ran aground in the shallows.
As for the Athenians, when they saw what was happening, they took courage, and at a single word of command gave a shout and dashed at them. But the Peloponnesians had made so many mistakes and were at present in such disorder, that, although they resisted a little while, they soon turned and fled to Panormus, whence they had put to sea.
The Athenians gave chase, and not only captured the six ships that were nearest, but also recovered their own ships which the enemy had disabled in the beginning of the fight near the shore and taken in tow; and of the men they killed some and took others alive.
