Pyrrhus, king of Epirus, Macedonia's western neighbour, was a general of mercurial ability, widely renowned for his bravery, but he did not apply his talents sensibly and often snatched after vain hopes, so that Antigonus used to compare him to a dice player, who had excellent throws, but did not know how to use them. When the Gauls defeated Ptolemy Ceraunus and the Macedonian throne became vacant, Pyrrhus was occupied in his campaigns overseas. Hoping to conquer first Italy and then Africa, he got involved in wars against Rome and Carthage, the two most powerful states in the western Mediterranean. He then lost the support of the Greek cities in Italy and Sicily by his haughty behaviour. Needing reinforcements, he wrote to Antigonus as a fellow Greek king, asking him for troops and money, but Antigonus politely refused. In 275 BC, the Romans fought Pyrrhus at the Battle of Beneventum which ended inconclusively, although many modern sources wrongly state that Pyrrhus lost the battle. Pyrrhus had been drained by his recent wars in Sicily, and by the earlier "Pyrrhic victories" over the Romans, and thus decided to end his campaign in Italy and return to Epirus.
