History of the Peloponnesian War

When they, therefore, after staying ten days, were suffering from the severe weather, had no provisions, and found none of their plans succeed, they retired to Naxos, and having made a palisade round their encampment, took up their winter quarters there. They also sent a trireme to Athens for both money and cavalry, to join them in the spring.

The Syracusans, on their part, both built in the course of the winter a wall to their city, along the whole quarter looking towards Epipolae, including the Temenites. to prevent their being circumvallated so easily as they would with a less circuit, in case of their being defeated; and also fortified Megara as an out-post, and another in the Olympieum. They fixed palisades, too, along the edge of the sea, at all points where there were facilities for landing.
