Where were the German forces defeated in north Africa?

The German forces were primarily defeated in North Africa at the Second Battle of El Alamein, which took place from October to November 1942. This decisive battle marked a turning point in the North African Campaign, as British Commonwealth forces, led by General Bernard Montgomery, successfully repelled the Axis troops under General Erwin Rommel. Following this defeat, the German and Italian forces were forced into a retreat, ultimately leading to their surrender in Tunisia in May 1943.
