Not so much a secret weapon as new tactics did the trick.

Any attack that could get around it would leave it floundering like a beached whale. Blitzkrieg was the means by which Germany simply went around the whole Line. By doing this, the Maginot Line was isolated and the plan that soldiers in the Line could assist the mobilised French troops was a non-starter. The speed with which Germany attacked France and Belgium in May 1940, completely isolated all the forts. The German attack was code-named “cut-of-the-sickle” (Sichlschnitt) – an appropriate name for the attack.
