History of the Peloponnesian War

For though the Syracusans were masters by land, yet seeing they hindered them but with few galleys from the liberty of the sea, they made preparation, and were gathering together a fleet with intention to resist them.

And the Athenians furnished out forty galleys to send into Sicily, conceiving that the war there would the sooner be at an end and desiring withal to train their men in naval exercise.

Therefore Pythodorus, one of the commanders, they sent presently away with a few of those galleys, and intended to send Sophocles, the son of Sostratides, and Eurymedon, the son of Thucles, with the greatest number afterwards.
