This short story appeared in the April, 1943 issue of Argosy. There is no mention of the Foreign Legion in this one but there is a besieged desert fort, some Méharistes, a battery of 75’s, spahis and a generic force of French regulars holding out against a German Mechanized force. This motley force is led by a French Colonel of the Reserves who gets mobilized from his civilian job as movie director.
Desert Finale was written by the the movie maker Charles Marquis Warren. It was released in 1943 at the height of the war and at this time Warren was still starting out in the movie business. He also wrote fiction for the pulps and several of his stories became best sellers. He joined the Navy and served in the Pacific Theater and returned to Hollywood after the war where he would be involved in either writing, producing or directing several movies as well as the first two seasons of the T.V. show Gunsmoke.
