History of the Peloponnesian War

When their preparations had been made, the Corinthians, taking provisions for three days, put off by night from Cheimerium with the intention of giving battle,

and at daybreak as they sailed along they descried the ships of the Corcyraeans out at sea and sailing to meet them.

And as soon as they saw one another, they drew up in opposing battle lines, the Attic ships on the right wing of the Corcyraeans, who themselves held the rest of the line forming three divisions, each under the command of one of the three generals.

So the Corcyraeans arrayed themselves; but the right wing of the Corinthian fleet was held by the Megarian ships and the Ambracian, in the centre were the other allies with their several contingents, while the left was held by the Corinthians themselves with their best sailing ships, opposed to the Athenians and the right wing of the Corcyraeans.
