The Carthaginians and the Greeks spent centuries fighting over Sicily. By the late 300s BCE, Agathocles, tyrant of Syracuse, was the undisputed master of the Sicilian Greeks. Carthage besieged his city, trapping him and his army within. However, with the bulk of their forces in Sicily, Carthage itself lay undefended. Realizing this, Agathocles snuck out of the city by ship and landed in North Africa, threatening Carthage directly. Carthage was forced to recall its army for its own defense, saving Syracuse. This strategy would later by used by Scipio Africanus to great effect against Hannibal’s Carthage, as well.
