The folly that was Maginot, 78 years on.
Built over two decades at the expense of huge portions of the French defense budget, the brainchild of French Minister of War André Maginot– some 5,000 interconnected concrete and steel blockhouses arrayed against Germany– was to provide a huge defensive line for “la Guerre de longue durée” (the war of the long duration) just in case the Germans ever came back.

Of course, the Germans ran around the wall through the Low Country and Ardennes and the vaunted line was rolled up largely intact after the Battle of France, some 78 years ago today.
Something kinda like this:
The Franco-German Armistice of 22 June 1940 was signed at 18:36 near Compiègne, France, knocking the French ostensibly out of WWII after just nine months of campaigning. Of course, the Vichy regime was non-viable from the start and by November 1942 the Germans went ahead and occupied the whole of metropolitan France as De Gaulle grew in power from London, but that is a whole different story.

Nonsense. The Germans had to go round the line rather than assault it. It did everything it promised it could and would do. The fatal flaws were French strategic planning; inability to learn from the lessons of WW1; a failure to adept to a changing world.
The Germans did not and defeated a numerically superior enemy in a breath taking 6 week campaign. The world will probably never see such a victory again, remember the French army was considered the best in Europe and actually had more tabnks than the Germans.

IIRC the French had had strong forces at Sedan up until a couple of days before the Germans appeared.
