I wonder at times if the French high command of 1940 would also have failed at 1914. In the later case, they were also caught rather red-handed, but they managed to cobble together a blocking formation that stopped the German advance. In 1940 on the other hand, one thing Marc Bloch complained about was declaring many a city an opine city and forego any resistance out of fear of the city getting damaged at the expense of the nation at large.
