The Dishonored Medal (1914)

While with the French Foreign Legion in Algeria, Lt. Dubois seduces the lovely Zora, leaving her with a child and his medal for bravery. Sheik Achmed generously befriends Zora, and when she is killed in an accident he raises her son, El Rabb, as his own, and soon El Rabb and Achmed's biological son Bel Khan become best friends. Years later Lt. Dubois, now a general, is dispatched to Algeria to crush a revolt led by El Rabb and Bel Khan--and he doesn't know that El Rabb is his son--who wears his father's medal around his neck.
