User:Acroterion/SF Alpes Maritimes

The Fortified Sector of the Maritime Alps (Secteur Fortifié des Alpes-Maritimes) 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 Nice.

Command
The Alpes-Maritimes sector was under the overall command of the French Army of the Alps, headquartered at Valence, under the command of General Olry. Subordinate to the Army of the Alps was the 15th Army Corps under General Montagne. The SF Alpes-Maritimes itself was commanded by General Magnien at Nice. The interval troops, the army formations that were to provide the mobile defense for the sector, to support and be supported by the fixed defenses, were the 65th Infantry Division, having succeeded the 29th Infantry Division in October 1939. Artillery support for the sector was provided by the 157th, 158th and 167th Position Artillery Regiments (Régiment d'Artillerie de Position (RAP)), which controlled both fixed and mobile artillery, commanded by Lt. Colonel Charnasson, Lt. Colonel Fournial and Colonel Carrour, respectively. The 29nd ID was made up of Class B reservists, not suited for sustained combat.

Description
The sector includes, in order from west to east, the following major fortified positions, together with the most significant casemates and infantry shelters in each sub-sector:
