A continuous Maginot-style barrier differed from a network of smaller fortified blocking points. Pillboxes at road junctions, bridges, and river crossings could make rapid movement harder and let small defending forces delay a larger attacker. Defensible concrete positions also gave troops a reason to hold when higher command was retreating, buying time for reinforcements. In the wider counterfactual, these land defenses matter because the feasibility of a German Channel landing depends on which routes around the fortified frontier remain open.

A discussion of Belgium and the Ardennes explains how modest forts at roads, bridges, and river crossings could delay an advance without reproducing the Maginot Line.
