History of the Peloponnesian War

With this mind the people of Athens received the Corcyraeans into league, and when the Corinthians were gone, sent ten galleys not long after to their aid.

The commanders of them were Lacedaemonius the son of Cimon, Diotimus the son of Strombichus, and Proteas the son of Epicles,

and had order not to fight with the Corinthians unless they invaded Corcyra or offered to land there or in some other place of theirs, which, if they did, then with all their might to oppose them. This they forbad, because they would not break the peace concluded with the Peloponnesians. So these galleys arrived at Corcyra.
