Battle of Cannae

Battle of Cannae

Overview

The Battle of Cannae (216 BCE) was Hannibal Barca's masterpiece — a devastating double envelopment of a much larger Roman army during the Second Punic War. It remains one of the most studied tactical victories in military history.

Key Facts

  • Location: Cannae, Apulia (southeastern Italy)

The Battle

  • Romans: ~86,000; Carthaginians: ~50,000
