In 1942 the Allies launched Operation Torch, which was a compromise operation that met the British objective of securing victory in North Africa, while allowing American armed forces the opportunity to engage in the fight against Nazi Germany on a limited scale.
After the Allied landings in North-West Africa, and subsequent battles against the Vichy France forces (who then changed sides), the Allies finally encircled the Axis forces in northern Tunisia and forced their surrender.
