On November 8, 1942, the military forces of the United States and the United Kingdom launched an amphibious operation against French North Africa, in particular the French-held territories of Algeria and Morocco. That landing, code-named 'Torch,' reflected the results of long and contentious arguments between British and American planners about the future course of Allied strategy â?? arguments that were finally stilled by the intervention of the American president, Franklin D. Roosevelt. In both a direct and an indirect sense, Torch's impact was enormous on the course of Anglo-American strategy during the remainder of the war. It may have been the most important strategic decision that Allied leaders would make. In fact, this amphibious operation inevitably postponed the landing in France until 1944, but at the same time it allowed the United States to complete mobilization of its immense industrial and manpower resources for the titanic air and ground battles that characterized the Allied campaigns of 1944.
