Nick Lloyd, Professor of Modern Warfare at King's College London and author of 'The Eastern Front: A History of the Great War, 1914-1918,' dives into the critical yet often overlooked Eastern Front of World War I. He discusses the significance of the Battle of Tannenberg, revealing its strategies and the chaos within the Russian army. Lloyd explores the impact of munitions shortages on Russia's war effort, the collapse of their forces leading to revolution, and Lenin's dramatic return, challenging the very fabric of the war and reshaping geopolitics.
