A similar idea to the Schlieffen Plan was used by Hitler's generals Erich von Manstein and Heinz Guderian in World War II. In that war, Germany invaded France by attacking Belgium and The Netherlands. Because in the Schlieffen Plan Germany attacked mostly through northern Belgium, France thought Germany would do this again. France put most of her soldiers in north Belgium. But Germany invaded mostly through "South" Belgium. German troops marched to the sea and trapped half of the French Army in northern Belgium. Because the trapped French troops were starving and could not get any more food, they surrendered. France tried to continue fighting but was too weak to resist and surrendered.
