History of the Peloponnesian War

The same day, at a late hour, Astyochus also put out, and taking one Chian vessel in addition to his own, sailed to Lesbos, to render it whatever assistance he could. Accordingly he came to Pyrrha, and thence the next day to Eresus, where he heard that Mitylene had been taken by the Athenians on the first assault.

For the Athenians, immediately on sailing to the place, unexpectedly put into the harbour, and defeated the Chian ships; and having landed, and conquered in a battle those who opposed them, they took possession of the city.
