History of the Peloponnesian War

And the Athenians manned forty ships to send to them; thinking that so the war in that quarter would be more speedily brought to a conclusion, and at the same time wishing to practise their men in seamanship.

They despatched therefore one of their commanders, Pythodorus, with a few ships; intending to send out Sophocles son of Sostradides, and Eurymedon son of Thucles, with the larger squadron.

So Pythodorus, being now in command of Laches' ships, sailed at the close of the winter to the fort of the Locrians, which Laches had formerly taken; and returned after being defeated in battle by the Locrians.
