The Maginot Line, a defensive string of forts with enfilading firepower, was built by France between WWI and WWII. Conceived by Minister of War Andre Maginot, it was meant to forestall another German invasion until troops could arrive. But the French began to think of the line as a substitute for manpower. When Belgium declared neutrality and exposed France's flank, Germany was able to sidestep the line. We'll visit the "impregnable" line's forts, observation turrets, and underground railroads.
