In 359/8 BC Dionysius II had made peace with Carthage. Carthage probably profited from the political instability on Sicily because it weakened the military power of the Greeks. As a consequence they tried to prevent Timoleon from setting foot on Sicily in 345/4 BC, but were unsuccessful. A confusing siege of Syracuse ensued in 344/3 BC with Timoleon, Dionysius, Hicetas and his Carthaginian allies each controlling different parts of the city. The two primary sources which describe the siege, Diodorus Siculus and Plutarch, give very different accounts. According to Plutarch Dionysius surrendered the acropolis to Timoleon right away and was expelled to Corinth. Diodoros states that this happened at the end of the siege in 343/2 BC. The Carthaginians broke off the siege and retreated. Timoleon then attacked the forces of Hicetas and drove them out of Syracuse.
