Explanation: In the Second Punic War, Hannibal, the leading Carthaginian ('Punic') general, invaded Italy, the heartland of the Roman Republic.
... he ultimately spent almost 15 years fighting in Italy, with some success in battle, but little progress made in reducing the Roman Republic's ability or eagerness to continue the fight. Stubborn Roman bastards!
Eventually, without the necessary success in bringing the Roman Republic to the negotiating table for peace, Hannibal had to withdraw to defend North Africa, where the Roman Republic emerged victorious and imposed a brutal peace of their own on Carthage.
