History of the Peloponnesian War

The Corcyraeans were in their camp at Leukimme, when these twenty ships from Athens, under the command of Glaucon, the son of Leagrus, and Andocides, son of Leogoras, bore on through the corpses and the wrecks, and sailed up to the camp, not long after they were sighted.

It was now night, and the Corcyraeans feared that they might be hostile vessels; but they soon knew them, and the ships came to anchor.

The next day the thirty Athenian vessels put out to sea, accompanied by all the Corcyraean ships that were seaworthy, and sailed to the harbor at Sybota, where the Corinthians lay, to see if they would engage.
