Double Envelopment is a military maneuver used to encircle an enemy force from two sides simultaneously. This tactic aims to cut off the enemy's retreat and supply lines, forcing them into a position where they can be overwhelmed. It is often employed in battles where one side seeks to exploit weaknesses in the enemy's formation. The success of Double Envelopment relies on coordination and speed. By attacking from both flanks, the encircling forces can create confusion and disrupt the enemy's command structure. Historical examples include the Battle of Cannae, where Hannibal effectively used this tactic against the Roman army.
