History of the Peloponnesian War

About the same time, the twenty ships of the Peloponnesians that were in Piraeus, which had been chased to land at the time we last mentioned them, and were blockaded by the Athenians with an equal number, having made a sudden sally against the Athenian squadron, and defeated it in an engagement, took four of the ships, and after sailing back to Cenchrea, proceeded to prepare again for their voyage to Chios and Ionia. Astyochus also joined them from Lacedaemon, as high admiral, to whom now belonged the command of all the naval forces.
