Encirclement is a military strategy where forces surround an enemy, cutting off their escape routes and supplies. This tactic aims to isolate the opponent, making it difficult for them to receive reinforcements or retreat. By creating a perimeter around the enemy, the encircling forces can apply pressure and force a surrender or defeat. In history, encirclement has been used in various conflicts, such as during World War II when the Soviet Union encircled the German army at Stalingrad. This decisive maneuver led to a significant turning point in the war, showcasing the effectiveness of encirclement in warfare.
