They that fled upon the losing of the first wall and put themselves into boats and into a certain ship got hardly into the camp; for whilst the Syracusians in the great haven had yet the better in the fight upon the water, they gave them chase with one nimble galley. But by that time that the other two walls were taken, the Syracusians upon the water were overcome; and the Athenians which fled from those two walls got to their camp with more ease.

For those Syracusian galleys that fought before the haven's mouth, having beaten back the Athenians, entered in disorder, and falling foul one on another, gave away the victory unto the Athenians, who put to flight not only them, but also those other by whom they had before been overcome within the haven, and sunk eleven galleys of the Syracusians and slew most of the men aboard them, save only the men of three galleys, whom they took alive.

Of their own galleys they lost only three. When they had drawn to land the wreck of the Syracusian galleys and erected a trophy in the little island over against Plemmyrium, they returned to their camp.

The Syracusians, though such were their success in the battle by sea, yet they won the fortification in Plemmyrium, and set up three trophies, for every wall one. One of the two walls last taken they demolished; but two they repaired and kept with a garrison.
