It should be noted that the British fought the Italians long before the Afrika Corps and Rommel arrived in North Africa.

Prior to WW2, Italy started a war against the British colonies around Somalia. Later, the battles were confined to the northern coastal countries of Africa. The fighting started in Somlia and Absyannia and progressed to Lybia. The Americans landed troops in Algiers in late 1942 and advanced across North Africa and converged with the British at Tunisia.
