Field Marshal Schlieffen succeeded Moltke and directed German planning in the lead up to World War I. He advocated the "strategy of annihilation" but was faced by a war on two fronts against numerically superior opposition. The strategy he formulated was the Schlieffen Plan, defending in the east while concentrating for a decisive victory in the west, after which the Germans would go on to the offensive in the east. Influenced by Hannibal's success at the Battle of Cannae, Schlieffen planned for a single great battle of encirclement, thereby annihilating his enemy.
