Le mercredi 15 mai 1940, dans le petit village ardennais de La Horgne à l’ouest de Sedan, les cavaliers de la 3e Brigade de Spahis (2e Régiment de Spahis Algériens de Tlemcen et 2e Régiment de Spahis Marocains de Marrakech) tentent d’arrêter une partie de la plus moderne Panzer-Division de la Wehrmacht. L’histoire commémorative a retenu que la 3e Brigade de Spahis aurait été tout simplement « anéantie » en une dizaine d’heures de combats, non sans avoir auparavant mis hors de combat un bon millier de soldats allemands. De son côté, l’histoire scientifique dénombre 50 Spahis et 31 soldats allemands tués. Plus de 76 ans après les faits, il est plus que temps d’en finir avec la légende du « massacre inutile de 700 Spahis chargeant à cheval les chars allemands à La Horgne ». / Wednesday, May 15, 1940, in the small Ardennes village of La Horgne, west of Sedan, the troopers of the 3rd [Cavalry] Brigade of Spahis (2nd Regiment of Algerian Spahis from Tlemcen and 2nd Regiment of Moroccan Spahis from Marrakech) try to stop a part of the most modern Panzer-Division of the Wehrmacht. Commemorative History has focused on a 3rd Brigade of Spahis that was simply "annihilated" in about ten hours of fighting, but not before putting out of action a thousand German soldiers. For its part, the scientific History takes into account 50 Spahis and 31 German soldiers killed in action. More than 76 years after the fact, it is more than time to put an end to the legend of the "useless slaughter of 700 Spahis charging German tanks on horseback at La Horgne".

The evolution of United States military doctrine was heavily influenced by the Wehrmacht and their early Blitzkrieg campaigns during World War II. This thesis traces the origins of this development and shows how the context of the Cold War led to a heavy influence by the Wehrmacht on American military doctrine. By analyzing studies conducted by the United States Army Historical Division from 1946-1961, I will show how these studies left a profound impact on American Military doctrine, particularly in the context of the Cold War. I will show the development of the Active Defense Doctrine and AirLand Battle during the 1970s and 1980s were largely influenced by lessons learned from the Wehrmacht. By comparing these doctrines with the Wehrmacht's Truppenführung, the influence is undeniable. Finally, I will show how the American military put these lessons into practice during Operation Desert Storm in 1991.
