From the back cover:
In 1940 a British offensive in the Western Desert provoked a major Italian military disaster. By early February 1941 the whole of Cyrenaica had been lost, and German help became necessary to avoid the loss of the entire of Libya. On 14 February 1941 the first echelons of German troops hurriedly arrived at the port of Tripoli, starting the 27-month German engagement in Northern Africa. This book covers the complex and oft-changing organisation and structure of German forces in North Africa from their first deployment through to the conclusion of the battle of El Alamein, an engagement that irrevocably changed the strategic situation in the Western Desert.
