History of the Peloponnesian War

Thus far victory was with the Peloponnesians, and the Athenian fleet destroyed; the twenty ships in the right wing being meanwhile in chase of the eleven Athenian vessels that had escaped their sudden movement and reached the more open water. These, with the exception of one ship, all out-sailed them and got safe into Naupactus, and forming close in shore opposite the temple of Apollo, with their prows facing the enemy, prepared to defend themselves in case the Peloponnesians should sail in shore against them.

After a while the Peloponnesians came up, chanting the paean for their victory as they sailed on; the single Athenian ship remaining being chased by a Leucadian far ahead of the rest.

But there happened to be a merchantman lying at anchor in the roadstead, which the Athenian ship found time to sail round, and struck the Leucadian in chase amidships and sank her.

An exploit so sudden and unexpected produced a panic among the Peloponnesians; and having fallen out of order in the excitement of victory, some of them dropped their oars and stopped their way in order to let the main body come up—an unsafe thing to do considering how near they were to the enemy's prows; while others ran aground in the shallows, in their ignorance of the localities.
