The Entella War was a conflict between Carthage and the Greek city-states of Sicily which occurred amid the Sicilian Wars of the 4th century BC. While the Carthaginians and the Greek poleis of central and eastern Sicily had been in a state of incessant war since the early 5th century BC, the Carthaginian ruler Himilco II escalated the conflict in 399 BC by ordering an offensive in Sicily. His general Medur captured Entella (Contessa Entellina) from the Greek city-state of Acragas, provoking an Acragantine counterattack led by Archon Hermolaos himself. The Acragantines were successful in retaking Entellina after Medur's army withdrew to the Carthaginian stronghold of Motya (Marsala), but, over the next few years, Entellina would change hands several times as both occupying armies took turns leaving, losing, and retaking the town. Himilco responded by dispatching his general Batza to Sicily with a reinforcement army including large numbers of Carthaginian hoplites, while his admiral Surulio stalked the northern coast of Sicily. By 397 BC, this Carthaginian counterattack had succeeded in recapturing Entellina. In 396 BC, Hermolaos and his general Hyakinthos led their armies in an invasion of Entella, aiming to drive back the Carthaginians. They recaptured Entella in 395 BC, and, in 394 BC, the Syracusan tyrant Dionysius I persuaded the Acragantines to join him in a two-pronged attack against Carthage: an Acragantine naval expedition would be sent to attack the Carthaginian port town of Kerkouane in North Africa, while the Syracusan general Hipparinus would march overland from Kephaloidion (Cefalu) to attack the Carthaginian stronghold of Motya (Marsala) on Sicily's western coast. In 394 BC, the Syracusans and Carthaginians both suffered heavy losses in a failed Syracusan attack on Motya, but, the following winter, the Syracusan army - bolstered by mercenaries - succeeded in taking the weakened city by storm. At the same time, the two Acragantine fleets sent against Kerkouane were destroyed by Himilco and Surulio's fleets in a naval battle off the coast of Tunisia, but, by then, the Carthaginians had been driven from Sicily, ending the Entella War. However, Carthage remained at war with the Greek cities of Sicily, and the Syracusans would launch their own invasion of Africa in 382 BC.
