Schlieffen Plan Failures

The Schlieffen Plan, initially a strategic blueprint for a swift victory, faltered due to inflexibility and unexpected obstacles, leading to a prolonged conflict. The failure at the Battle of the Marne marked a turning point, forcing Germany into a two-front war. Interestingly, a variation of this plan was later employed in World War II, demonstrating both the adaptability and the pitfalls of military strategy.
