History of the Peloponnesian War

Meanwhile Astyochus, the Lacedaemonian admiral, sailed with four ships from Cenchreiae, as he had purposed, and arrived at Chios. And on the third day after his coming the twenty-five Athenian ships sailed to Lesbos, being under the command of Leon and Diomedon; for Leon had arrived afterwards with a reinforcement of ten ships from Athens.

On the same day, but at a later hour, Astyochus put to sea, and taking besides his own one Chian ship sailed to Lesbos, in order to give what aid he could. On that day he reached Pyrrha, and thence on the next day Eresus, where he learned that Mytilene had been taken by the Athenians at the first assault.
