The Maginot Line, the massive series of fortifications built by France in the 1930s to defend its borders with Germany and Italy, is perhaps the most maligned collection of fortifications ever built.

The kind of defence we want is not something akin to the Maginot Line, but more like manoeuvre warfare.

Second, the forts of France's Maginot Line were not tactically outflanked, as myth has it.
