He fought a war with Carthage from 397 BC to 392 BC with mixed success; his attempts to drive the Carthaginians entirely out of the island of Sicily failed, and at his death they were masters of at least a third of it. He also carried on an expedition against Rhegium, capturing it and attacking its allied cities in Magna Graecia. In one campaign, in which he was joined by the Lucanians, he devastated the territories of Thurii and Croton in an attempt to defend Locri.
