History of the Peloponnesian War

In the first place, then, the Athenians went out and ravaged a part of the Syracusan territory, about the Anapus, and were superior in force, as they had originally been, both by land and by sea: (for in neither way did the Syracusans come out against them, except with their cavalry and dart-men from the Olympieum.)

Afterwards, Demosthenes resolved first to make an attempt on the counter-work with engines. But when the engines, after he had brought them up, were burnt by the enemy who were making a defence from the wall, and they were beaten back when charging at many points with the rest of his forces, he determined to delay no longer; but having gained the assent of Nicias and the rest of his colleagues, according to the plan he had formed, he proceeded to the attempt on Epipolae.
