History of the Peloponnesian War

The next day, the Athenians, beginning at their circular wall, built onwards to that crag over the marshes, which on that part of Epipolae looketh to the great haven, and by which the way to the haven, for their wall to come through the plain and marsh, was the shortest.

As this was doing, the Syracusians came out again and made another pallisado, beginning at the city, through the middle of the marsh, and a ditch at the side of it, to exclude the Athenians from bringing their wall to the sea.

But the Athenians, when they had finished their work as far as to the crag, assaulted the pallisado and trench of the Syracusians again. And having commanded their galleys to be brought about from Thapsus into the great haven of Syracuse, about break of day went straight down into the plain, and passing through the marsh, where the ground was clay and firmest, [and partly] upon boards and planks, won both the trench and pallisado, all but a small part, betimes in the morning, and the rest not long after.
