#35, Battle of Cannae: The Ancient World's Most Perfect Massacre
At Cannae on August 2, 216 BC, Hannibal Barca's 50,000-man Carthaginian army killed between 55,000 and 70,000 Roman soldiers in a single afternoon, the highest single-day death toll in Western military history until the 20th century. The Roman Republic fielded 86,000 men, the largest army it had ever assembled, and lost roughly 80% of them in approximately eight hours of fighting. An estimated 600 Roman soldiers were killed per minute at the height of the battle.
Hannibal's double envelopment at Cannae remains the most studied tactical maneuver in military history. His center deliberately gave ground, drawing the Roman legions deeper into a crescent that slowly closed around them. Numidian and Spanish cavalry routed the Roman horsemen on both flanks, then wheeled into the Roman rear. The legions were compressed into a suffocating mass where soldiers in the center couldn't raise their weapons. Roman consul Lucius Aemilius Paullus, 29 of 48 military tribunes, and 80 Roman senators died on the field. Yet Rome refused to surrender, rebuilding its legions and eventually destroying Carthage. Cannae's double envelopment was studied by Schlieffen, Schwarzkopf, and every military academy in the modern world.
