The Fortified Sector of the Dauphiné ("Secteur Fortifié du Dauphiné") was the French military organization that in 1940 controlled the section of the Alpine Line portion of the Maginot Line facing Italy in the vicinity of Briançon. By comparison with the integrated defenses of the main Maginot Line, or even of the Fortified Sector of the Maritime Alps to the south, the Dauphiné sector consisted of a series of distinct territories that covered two main invasion routes into France: the route from Turin over the Col de Montgenèvre to Briançon and Grenoble, and the route from Coni over the Col de Larche to Barcelonette and Gap. The sector was the scene of probing attacks by Italian forces during the Italian invasion of France in 1940, in which the French defenses successfully resisted Italian advances until the June 1940 armistice that granted Italy access to southeastern France.
