History of the Peloponnesian War

After this, with the vessels which had joined them from Abydus and the rest, amounting in all to eighty-six, they besieged Elaeus that day, and when it did not surrender, sailed back to Abydus.

As for the Athenians, they had been deceived by their scouts, and did not imagine that the passage of the enemy's fleet could ever escape their vigilance, but were leisurely assaulting the walls of Eresus. When, how ever, they were aware of it, they immediately left Eresus, and proceeded with all haste to the defence of the Hellespont.

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.
