" In a series of engagements in Tunisia during World War II that reached a climax near the Algerian border at the Kasserine Pass, combined Italian and German forces in February 1943 drove American and French troops back about fifty miles from the Eastern to the Western Dorsale mountains. These events grew out of two actions: the British victory at El Alamein on 23 October 1942, which precipitated the retreat of German General Erwin Rommel's army across Libya and into southern Tunisia; and the Anglo-American invasion of French North Africa on 8 November 1942, which prompted the Axis nations to dispatch troops from Italy to northern Tunisia. By January 1943, Rommel's troops, pursued by Lieutenant General Bernard L. Montgomery's Eighth Army, were settling into the Mareth positions. At the same time, General D. Juergen von Arnim held Bizerte and Tunis against Lieutenant General Kenneth Anderson's First Army, composed of British, French, and American units." Dictionary of American History
