According to Dietrich's plan, LXVII Armeekorps would secure 6th Panzer Army's northern flank. By sidestepping Monschau to seize the area of poor roads, forested hills, and upland moors of the Hohe Venn, LXVII's divisions would block the main roads leading into the breakthrough area from the north and west. Simultaneously, I SS Panzer Corps to the south would use its three infantry divisions to punch holes in the American line and swing northwest to join the left flank of LXVII Corps. Together, the infantry divisions would form a solid shoulder, behind which the tanks of I and II SS Panzer Corps would advance along 6th Panzer Army's routes leading west and northwest.
