The History of the Grecian War (1.29.4-1.30.1)

The herald was no sooner returned from the Corinthians with an answer not inclining to peace but having their galleys already manned and furnished to the number of eighty sail (for forty attended always the siege of Epidamnus), they put to sea and, arranging themselves, came to a battle in which the Corcyraeans were clearly victors;

and on the part of the Corinthians there perished fifteen galleys. And the same day it happened likewise that they that besieged Epidamnus had the same rendered unto them, with conditions, that the strangers therein found should be ransomed and the Corinthians kept in bonds till such time as they should be otherwise disposed of.

The battle being ended, the Corcyraeans, after they had set up their trophy in Leucimna, a promontory of Corcyra, slew their other prisoners but kept the Corinthians still in bonds.
