History of the Peloponnesian War

The Athenians, upon advertisement that they were set forth, rising with their whole army, both themselves and such of the Siculi and others as went with them, and going aboard their galleys and boats, in the beginning of the night set sail for Syracuse.

In the morning betimes the Athenians disbarked over against Olympieium to make their camp. And the Syracusian horsemen, who were at Catana before the rest, finding the camp risen, came back to the foot and told them; whereupon they went all together back to the aid of the city.

In the meantime, the way the Syracusians had to go being long, the Athenians had pitched their camp at leisure in a place of advantage, wherein it was their own power to begin battle when they list, and where both in and before the battle the Syracusian horsemen could least annoy them. For on one side there were walls and houses and trees and a lake that kept them off; on the other side steep rocks;

and having felled trees hard by and brought them to the seaside, they made a pallisado both before their galleys and towards Dascon. And on that part that was most accessible to the enemy, they made a fort with stone (the best they could find, but unwrought) and with wood, and withal pulled down the bridge of the river Anapus.
