First of all, go see The Golden Compass, right now. It has everything I love about the Enlightenment combined with everything I love about armored polar bears, aerial witch squadrons, steampunk technology, and Sam Elliott. Not seeing this movie would be tantamount to murdering a part of your own soul.
As to the strip, the Great Age of Fortifications had passed away by Napoleon’s time. The grand fortresses of the Thirty Years War and the wars of Louis XIV on which so much intense effort and study had been lavished were brushed aside by the wars of mobility of Frederick and Napoleon. There were attempts at larger scale fortifications later, of course: the Maginot Line, the Siegfried Line, the beaches of Normandy, and all of them failed more or less miserably.
