History of the Peloponnesian War

To this extent then the Peloponnesians had the advantage, and destroyed the Athenian ships; while their twenty vessels in the right wing were in pursuit of those eleven of the enemy that had just escaped their turn into the open gulf. They, with the exception of one ship, got the start of them and fled for refuge to Naupactus; and facing about, opposite the temple of Apollo, prepared to defend themselves, in case they should sail to shore against them.

Presently they came up, and were singing the paean as they sailed, considering that they had gained the victory; and the one Athenian vessel that had been left behind was chased by a single Leucadian far in advance of the rest.

Now there happened to be a merchant-vessel moored out at sea, which the Athenian ship had time to sail round, and struck the Leucadian in pursuit of her amid-ship, and sunk her.

The Peloponnesians therefore were panic-stricken by this sudden and unlooked for achievement; and moreover, as they were pursuing in disorder, on account of the advantage they had gained, some of the ships dropped their oars, and stopped in their course, from a wish to wait for the rest—doing what was unadvisable, considering that they were observing each other at so short a distance—while others even ran on the shoals, through their ignorance of the localities.
