Pyrrhus added the fleet of Syracuse to his own fleet. Syracuse possessed over 120 decked ships, 20 without decks and a royal
enneres, increasing his fleet to more than 200 ships. Heracleides, the ruler of
Leontini delivered his city and army of 4,000 infantry and 500 cavalry to him as well. After receiving many other Sicilian cities in alliance, he hoped he might even conquer Libya. Pyrrhus refused Carthaginian pleas for peace and attacked their territory on Sicily. He reduced their territory to
Lilybaeum, their last stronghold on western Sicily. Pyrrhus
laid siege to Lilybaeum, but was not able to take it because Carthage still controlled the sea and supplied the city well. He lifted the siege and started preparations to invade Libya with his fleet. By this time he was despised by the Sicilian Greeks for his authoritarian behavior. The last straw for the Sicilian Greeks was his execution of Thoenon. Even though Thoenon and Sostratus cooperated with Pyrrhus, he did not trust them. When Sostratus no longer felt safe and fled, he accused Thoenon of conspiring with Sostratus and had him killed. The Sicilian Greeks became hostile to him, with some cities allying themselves with the Carthaginians and the
Mamertines. At this point he decided to return to Southern Italy to support the
Samnites and
Tarentines, who were losing the war with the Roman Republic. == References ==
