History of the Peloponnesian War

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.

On the side of the Peloponnesians, the right wing was held by the Syracusans, the other by Mindarus himself and the fastest sailing vessels; on that of the Athenians, the left was held by Thrasylus, the right by Thrasybulus; while the other commanders took their position as might severally happen.
