Who they are

At the age of nine Hannibal was brought by his father to an altar and made to swear lifelong enmity to Rome. In 218 BC he led fifty thousand foot and horse and thirty-seven war elephants from Spain over the Alps and into Italy — a route the Romans thought impossible. Trebia, Lake Trasimene, and Cannae were all victories: at Cannae, outnumbered, he encircled and destroyed nearly seventy thousand Roman troops, the eternal textbook case of a battle of encirclement. For sixteen years afterward he ranged over Italy with no one able to beat him, and Rome adopted "Fabian tactics" of delay without battle, until Scipio struck straight at Carthage itself and, at Zama, dealt Hannibal the first defeat of his life. After the war he served as a magistrate in Carthage reforming its finances, was hunted by Rome, spent years in exile, and finally took poison: "Let us free the Romans from their long anxiety over one old man."

Key stories

The Battle of Cannae

In 216 BC Rome massed eighty thousand men for a decisive battle. Hannibal, with only fifty thousand, deliberately let his center infantry fall slowly back into a crescent, and the Roman legions packed together and charged the "retreating" center; on the wings the African heavy infantry closed in, and the Numidian cavalry, having routed the Roman horse, sealed the pocket from behind — eighty thousand men were bagged, and nearly seventy thousand died in a single day, among the fallen a consul and eighty senators. To this day it is the first lesson in the "annihilation" chapter of military academies everywhere, and the Schlieffen Plan was a magnified Cannae.

Hannibal at the gates

After Cannae the city of Rome was in daily panic, and "Hannibal ad portas" (Hannibal is at the gates) became a phrase Roman mothers used to frighten their children for centuries. But Hannibal never took the city — lacking siege engines and supplies, he counted on Rome’s alliance system collapsing, and most of the allied cities, astonishingly, did not revolt. The complaint of his cavalry commander Maharbal is famous through the ages: "Hannibal, you know how to win a victory, but you do not know how to use one."

Version differences

The exact route over the Alps (which pass) has been argued for two thousand years; the numbers and losses of the war elephants differ from source to source.

Echoes today

Below are how modern works borrow or reinterpret this name or story — not the original material. The two differ, so keep them apart.

The battle of annihilation at Cannae"Cannae" became a military term for enveloping and wiping out an enemy on both flanks; the Schlieffen Plan called itself a magnified Cannae.
