"Victory comes from movement" was Schlieffen's principle for war.[1] Hindenburg expounded on Schlieffen's ideas as an instructor and later applied them during World War I. By employing such tactics, retreats and mobile defenses commanded by Hindenburg proved effective, and his Schwerpunkt attacks broke through the trench barrier on the Western Front. However, they failed to produce decisive victories because penetrating forces proved too slow to capitalize on their breakthroughs.[citation needed]
