History of the Peloponnesian War

And they took two of the Peloponnesian ships, which having on that occasion put out into the open sea more boldly than the rest, fell in with them. The next day they arrived and cast anchor at Elaeus, and bringing in from Imbros such ships as had taken refuge there, they were five days making preparations for the battle.

After this they fought in the following manner. The Athenians, drawn up in column, were sailing close along shore towards Sestos; while the Peloponnesians, observing this from Abydus, put out on their side also to meet them.

When they found that they were on the eve of an engagement, they extended their flank, the Athenians along the Chersonese, from Idacus to Arrhiana, with seventy-six ships; the Peloponnesians, on the other hand, from Abydus to Dardanus, with eighty-six.
