Nevertheless, Plutarch relates that Timoleon managed to defeat Hicetas in the Battle of the Damurias River. Mamercus was defeated by Timoleon in the Battle of the Abolus River, in which the Carthaginian soldiers he received from Gisco made up a large part of the casualties. After this defeat Carthage decided to make peace with Timoleon, to which he agreed. The terms were that Carthage was to keep its territory within the Lycus river, to restore the family and property to anyone who wished to move to Syracuse and that it would end their alliance with the tyrants. Mamercus fled to Messana where he took refuge with the tyrant of that city, Hippo. When Timoleon besieged Messana by land and sea, Hippo tried to escape aboard a ship, but was caught and executed by the city's inhabitants. Mamercus then surrendered to Timoleon. In the account of Diodorus Siculus Hicetas is mentioned as well, but Mamercus and Hippo are not. Diodorus does mention other tyrants which Timoleon deposed: the Campanians in Aetna, Nicodemus in Centuripae and Apolloniades in Agyrium.
