German Schlieffen Plan: This plan, named for it's originator, Count Alfred von Schlieffen, was a reaction to the German notion of encirclement. Any war for Germany would be a two front war. This plan would ensure a quick, 42 days to be exact, victory over France before their ally, Russia, could complete its mobilization. This would allow the German army to then concentrate all forces to the east in order to crush their second enemy, Russia.
