History of the Peloponnesian War

The next day the Syracusans remained quiet, without showing at all what were their plans for the future. Nicias, on the other hand, seeing that the battle had been a drawn one, and expecting that they would attack them again, compelled the captains to refit their ships, whichever of them had at all suffered; and stationed merchantmen before the stockade which had been fixed in the sea in front of their ships, to serve the purpose of an enclosed harbour.

These vessels he placed at intervals of two hundred feet from each other, that if any ship were hard pressed, it might have means of retreating in safety and sailing out again at leisure. The Athenians, then, continued to make these preparations during the whole day until the night.
