But this is too easy on a French Army that had bigger and more powerful tanks than the Germans in 1940 and which stratigically was utterly blind by hiding behind the Maginot Line when everyone knew that the Belgian border was wide open.

Only problem with the Maginot Line was that they defended it with too many troops. The Maginot line was well-built and a good investment.

And actually the Belgian border WASN'T wide open; the French heavily manned it and immediately dashed into Belgium when the German invasion began in 1940.

The one part that was "wide open" was a narrow area in the Ardennes across from Luxembourg; of course, the Germans shot through there behind the French forces dashing into Belgium.

I've seen accounts that the French plannned for the Ardennes as a "forced" avenue of approach and viewed it as a kill box? Is it true, and if so, where did they fail?
