History of the Peloponnesian War

After this they engaged in the following way. The Athenians formed in column and sailed close along shore to Sestos; upon perceiving which the Peloponnesians put out from Abydos to meet them.

Realising that a battle was now imminent, both combatants extended their flank; the Athenians along the Chersonese from Idacus to Arrhiani with seventy-six ships; the Peloponnesians from Abydos to Dardanus with eighty-six.

The Peloponnesian right wing was occupied by the Syracusans, their left by Mindarus in person with the best sailors in the navy; the Athenian left by Thrasyllus, their right by Thrasybulus, the other commanders being in different parts of the fleet.
