The document summarizes the North African campaign of World War 2 between the Allied and Axis forces from 1940 to 1943. It describes the key battles as the forces pushed back and forth across Libya and Egypt, culminating in the Allied victory at the Second Battle of El Alamein in late 1942. This turned the tide and allowed the Allies to take the offensive, invading Tunisia and forcing the surrender of Axis troops in North Africa in May 1943.
