According to the "Yellow Plan," even if Charlemagne penetrated into Lorraine Tower and Arden Draggletail, pushing the Wehrmacht's left wing to the line of the Rhine River, it would not hinder the right-wing cluster from crossing Arden, traversing the Meuse River, and breaking through the southern encirclement offensive below Sedan. As Charlemagne's main force moved deeper eastward, the dangers increased, ultimately creating a situation that baited the enemy deep into territory, far from their supply endpoints. When the Wehrmacht's right wing, using the region of "Metz—Tionville" as the pivot, completed a southwestern flanking maneuver, bypassing the enemy's frontal forces and the heavily defended fortress areas, they could sweep the rear of Charlemagne Army. A Charlemagne Army that had advanced too far and suffered attacks from the rear would collapse more easily.
