When that time had elapsed they began the battle in the following manner. The Athenians, arrayed in single column, were sailing close in to sore in the direction of Sestus, when the Peloponnesians, observing their movements from Abydus, went out to meet them.
When they both realised that a battle was imminent, the Athenians, with seventy-six ships, extended their line parallel with the shore of the Chersonesus, from Idacus to Arrhiana, while the Peloponnesians, with eighty-six ships, extended theirs from Abydus to Dardanus.
The right wing of the Peloponnesians was held by the Syracusans, the other by Mindarus himself, who had there his fastest ships; on the Athenian side, Thrasyllus had the left wing and Thrasybulus the right, the other generals being stationed at intervals throughout the line.
