History of the Peloponnesian War

The generals of the Syracusans, besides feeling confident in other respects, and intending, even without this, to make their preparations for marching to Catana, gave far too inconsiderate credence to the man, and immediately fixing a day on which they would be there, dismissed him; while they themselves (for by this time the Selinuntines and some other of their allies had also come) gave orders for all the Syracusans to march forth in a body. When their preparations were made, and the time at which they had agreed to come was near at hand, they set out for Catana, and bivouacked on the river Symaethus, in the Leontine territory.

The Athenians, on learning their approach, took the whole of their own force, with such of the Sicels, or any other people, as had joined them, and putting them on board their ships and boats, sailed by night to Syracuse.

And thus, when the morning came, the Athenians were landing on the ground opposite the Olympieum, for the purpose of securing their camp; and at the same time the Syracusan cavalry, having ridden up first to Catana, and found that the whole armament had put to sea, returned and carried the news to the infantry, when they all turned back together, and went to the aid of the city.
