“Over the ages, commanders have tried, mostly without success, to replicate Hannibal’s stunning double-envelopment: Frederick the Great, von Molke, and von Schlieffen, to name but a few.”

By Jim Stempel

IT’S DAWN, AUG. 2, 216 BC and lightning is about to strike the Roman Republic.

On a ridge overlooking an expansive plain in what’s now southeastern Italy, the Carthaginian general Hannibal Barca watches as a massive Roman army – eight enormous legions consisting of 87,000 infantry and cavalry – marches directly, irresistibly toward his troops arranged on the ground below. Two years earlier Hannibal had led his army over the Alps and descended into Northern Italy to harass and defeat the Romans time-and-again.

The Romans, now led by the Consul Varro, have assembled a massive force for one purpose only: to destroy the Carthaginian army. The general watches as dust swirls around the approaching Romans, their breastplates glinting in the rays of the rising the sun. He has been expecting them.

Feigning retreat for the past several days, Hannibal has drawn the weary Romans across miles of dry, barren land to the small village of Cannae in southeastern Italy where he now intends to make a stand. He has at his disposal at best 50,000 infantry and cavalry, but the odds do not bother him.

Near Cannae, he has placed his forward line in a crescent at the mouth of a small valley that rises like the letter ‘v’ from the plain. Upon each flank Hannibal has positioned his finest Carthaginian infantry, somewhat detached on small knolls. His heavy cavalry – a substantial force – waits in hiding on the sloping ground behind Cannae.

The Romans are the greatest military power of the era; their legions are well-trained, armed, and led. But Hannibal has studied their methods carefully, and because he knows precisely how they fight, he knows precisely how to defeat them. Forward crushing power is the essence of Roman tactics, and today Hannibal has decided to use that doctrine against them.

The Roman formation stretches over a mile from flank-to-flank. It’s a massive, seemingly unstoppable force. Yet Hannibal has chosen his position specifically to offset the enemy’s immense strength. The rising sun is shining directly in the Roman soldiers’ faces; the dry summer winds create a blinding cloud of grit and sand. Through the swirling dust and punishing glare, the Romans feel their way forward.

Finally spotting the Carthaginians arrayed for battle ahead, the Romans press hurriedly forward. At the mouth of the valley, both sides meet in a terrifying collision of flashing swords, flying spears, screams and horrific bloodletting.

Slowly, the Carthaginians give ground, backing into the valley – just as Hannibal has ordered. The Romans, sensing victory – expecting to overwhelm the center of the Carthaginian line – press ever forward, unaware they are being lured into a trap.

From above, the Carthaginian leader watches as the massive Roman formations crush into the ever-narrowing terrain below. Satisfied, he turns and nods. A smoke signal goes up, and the detached Carthaginian infantry sweep down upon both exposed flanks of the unsuspecting Romans. Hannibal’s cavalry thunders out from hiding, driving off the Roman cavalry then returning to attack the Romans from behind.

The legions are surrounded. Moreover, because of the narrowing constraints of the landscape the Roman units cannot maneuver, change fronts, or even bring their vast numerical superiority to bear. They have been trapped virtually shoulder-to-shoulder, like cattle in an enormous pen.

All day the Carthaginians hack away at the edges of the Roman formations, reducing it by the hour, until late in the afternoon the Romans are no more.

The historian Polybius writes that on the valley floor some 76,000 Romans and their allies lay dead; another 10,000 have been captured. The Carthaginians suffer a mere 5,700 casualties. The victory is unparalleled.

Rarely before or after has a military commander incorporated so many natural elements into a plan-of-battle – the breeze off the Adriatic, the rising sun, the dusty, hilly terrain – while luring his enemy to the site of their demise by means of a long, exhausting march.

But those tactical elements pale in comparison to the inversion of numerical superiority Hannibal achieved by trapping the vastly superior Roman legions in a valley where their enormous numbers became, no longer an advantage, but a handicap. Many Roman soldiers would accomplish little more that day than stand in the blazing sun for hours, awaiting the moment of their struggle and death.

“Hannibal excelled as a tactician,” Theodore Ayrault Dodge writes. “No battle in history is a finer sample of tactics than Cannae.”

In terms of tactical originality and sophistication, the Carthaginian victory at Cannae remains unequaled. Thus, has Hannibal’s astonishing victory over a substantially superior foe been acknowledged throughout history as perhaps the greatest military victory of all time.

According to military historian Robert L. O’Connell, Rome’s losses that day totaled “more dead soldiers than any other army on any single day of combat in the entire course of Western military history.”

Not surprisingly, Cannae has cast a long shadow over Western military thought and traditions, virtually sanctified over time as the gold standard of martial brilliance. Over the ages, commanders have tried, mostly without success, to replicate Hannibal’s stunning double-envelopment: Frederick the Great, von Molke, and von Schlieffen, to name but a few. It’s said Napoleon marched his army through numerous alpine passes just to walk in the great Carthaginian’s footprints.

More recently, General Norman Schwarzkopf readily admitted that the blueprint for Operation Desert Storm was taken fundamentally from Hannibal’s pincer movement at Cannae.

Yet, perhaps the most impressive salute to the great Carthaginian leader comes from former president and Allied Supreme Commander, Dwight Eisenhower. He wrote that every military leader “tries to duplicate in modern war the classic example of Cannae.” Dodge, Hannibal’s biographer agrees. writing, “Hannibal stands alone and unequaled.”

Hannibal Barca died in 184 BC, yet like a ghost, his achievements have haunted Western military thought and conventions for over 2,000 years. Indeed, his victory at Cannae still beckons.
