History of the Peloponnesian War

And such was the result; for the Syracusans no longer came against them on account of the fire, but withdrew again. Indeed, by this time succours had gone up to the lines from the Athenians below, who had repulsed the enemy in that part; and at the same time their ships from Thapsus were sailing, as they had been ordered, into the great harbour.

At the sight of this, those on the heights retreated with all speed, and the whole army of the Syracusans retired into the city, thinking that they would no longer be able with their present force to prevent the building of the wall down to the sea.

After this, the Athenians erected a trophy, restoring their dead to the Syracusans under a truce, and receiving back those who had fallen with Lamachus, as well as himself. And as they now had with them their whole force, both naval and military, they began from Epipolae and the cliffs, and circumvallated the Syracusans down to the sea with a double wall.
