What strategy did Hannibal use at the Battle of Cannae?

At the Battle of Cannae in 216 BC, Hannibal executed a brilliant military tactic known as double envelopment. This strategy involved surrounding the Roman army on all sides, effectively encircling them and cutting off their escape routes. Hannibal arranged his forces with weaker troops in the center, which initially drew the Romans in. As the Roman forces attacked and penetrated the center, Hannibal's cavalry and infantry on the flanks then closed in from the sides and behind.

This double envelopment led to a catastrophic defeat for the Romans, as they became trapped and were unable to organize a coordinated retreat or effective defense. The successful implementation of this tactic showcased Hannibal's strategic genius and remains a classic example of military maneuvering. The effectiveness of double envelopment at Cannae has been studied and admired throughout military history for its decisive and comprehensive execution in battle.
