 As the Algerians matched and sometimes exceeded the strides of the American units of the VI Corps and reached the Lauter along a front, de Lattre had no difficulty pressing his ambition on the Sixth Army Group commander, General Devers.Using the 3rd Algerian Division and a combat group from the 5th French Armored Division, again to be attached to the VI Corps, the French (organized as Task Force ("Groupement") de Monsabert) were to continue northward some beyond the Lauter River, thereby gaining limited Rhine River frontage inside Germany.The subsequent French advance pushed through the Bienwald, a large forested expanse just north of the Lauter through which bunkers, trenches, and other obstacles of the Siegfried Line were emplaced.
