Best known for moving elephants through high mountain passes in wintertime to the classic application of the double envelopment maneuver to surround and destroy a Roman army on the battlefield at Cannae, Hannibal's achievements have rarely been equaled and never surpassed. Not only did he grasp the importance of each of the elements of a military campaign, he mastered all of them to achieve the kinds of victories which soldiers still seek to emulate.Despite his status as a great general and his string of victories on the battlefield, Hannibal was defeated in the end. It was Rome, not Carthage that became the superpower of the ancient world. The story of Hannibal's tactical genius but strategic failure holds lessons today for those who are trying to understand why success on the battlefield does not always, or even frequently, lead to victory in war.
