The Unknown Story of the Southern
Maginot Line
The wild Maritime Alps are the most remote and least
known part of this country, a chain of vertiginous, snow-capped peaks and
narrow defiles running due south along the Franco-Italian border from
Switzerland down to the Mediterranean on the Riviera.
As a military historian, I’ve come here to remember
the heroic stand against overwhelming odds in June, 1940 of Gen. RenĂ© Olry’s
Army of the Alps: a little French Thermopylae.
The German offensive in the West that erupted on 10
May, 1940 was a revolutionary kind of fluid warfare based on fast-moving armor
and mechanized units, close air support, and advanced communications.
In only six weeks – by 20 June 1940 – France’s proud
army, considered the finest in the world, was shattered; 240,000 French
soldiers were killed or seriously wounded; 2,000 French tanks were destroyed by
the German “blitzkrieg.”
Germany’s generals had learned much from the slaughter
of World War I, vowing to make their troops mobile to avoid static warfare.
France’s hidebound generals, by contrast, planned to refight World War I in a
defensive campaign based on fortified regions and massed artillery.
France’s powerful Maginot Line forts, backed by
400,000 interval troops, was not outflanked, as is wrongly believed. The Line
achieved its twin goals of defending Lorraine’s iron and steel industry from a
surprise German attack and forcing the Germans to attack through Belgium or
Switzerland’s fortress chains.
The Maginot Line was never designed to defend the
entire Franco-German frontier. Not one of its major forts was taken by German
assault.
France’s unwieldy field army was scattered by flank
and rear attacks by German armor. France’s air force proved ineffective.
Britain’s army abandoned its French ally and ran for the coast.
As France lay dying, Italy’s swaggering dictator,
Benito Mussolini, frantic he might miss out on the spoils of war, declared war
on 10 June on France and Britain. Italy demanded France return former Italian
possessions of Nice, Cannes, Marseilles, and Menton.
France’s first Maginot fort, Rimplas, was begun in
1928 after “Il Duce” intensified his irredentist demands. A score of major forts
and smaller works were built to guard the river valleys and passes leading into
Italy. Sospel, the back door into Nice, received particular attention.
France’s Army of the Alps has been denuded of men and
material to oppose the relentless German advance on its rear down the Rhone
Valley. General René Olry, had only 35,000 men. Among them were light ski units
and elite Alpine infantry in their trademark big berets known as “tartes.”
Italian troops swarmed over the high mountain passes
and ridges running at high as 2900 meters. But their main attacks concentrated
on the Col de Larche with the road leading from Turin to Grenoble, Sospel, and
Menton.
The southern Maginot forts performed perfectly. They
spotted the advancing Italians and brought down a devastating crossfire of 75mm
shells on them. Other French 155mm heavy artillery units blasted the Italian
columns, guns and armored trains, forcing the Italians to retreat in disarray.
The famed French 75mm field and fortress gun was light but it could fire up to
18 shrapnel shells a minute, producing a lethal a blizzard of steel.
