History of the Peloponnesian War

Now the Athenians were at Sestos with eighteen ships; and when their friends gave them notice by fire signals, while they also observed the fires on the hostile shore suddenly appear numerous, they were aware that the Peloponnesians were entering the Hellespont. Accordingly that same night, sailing as quickly as they could, and keeping close under the shore of the Chersonese, they coasted along towards Elaeus, wishing to escape from the enemy's fleet into the open sea.

And they eluded the observation of the sixteen ships at Abydus, although orders for keeping guard had been before given by their friends who went to them, that they might be on the alert against the Athenians in case they should sail out. But descrying those with Mindarus in the morning, and being immediately chased by them, they had not all time to escape, but the greater part of them did, to Imbros and Lemnus; while four of the ships, which were sailing last, were overtaken off Elaeus.

One of these, which was stranded opposite the temple of Protesilaus, they took together with its crew, and two others without their crews; while the remaining one they burnt, after it had been deserted, close to Imbros.

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.

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.
