This historical analysis of the ill-fated Franco-British operation reveals how it nearly spelled defeat for the Triple Entente in WWI.   In December of 1916, General Robert Nivelle was appointed Commander-in-Chief of the French armies fighting the Germans on the Western Front. A national hero, he had enjoyed a meteoric rise to high command and public acclaim since the beginning of the Great War. In return, he proclaimed he 'had the formula' that would ensure victory and end the conflict in 1917. But his offensive was a bloody and humiliating failure for France, one that could have opened the way for French defeat. Historian David Murphy presents a penetrating, in-depth analysis of The Nivelle Offensive, demonstrating why it failed and underscoring its importance in the course of the First World War. Murphy describes how the charismatic officer used his charm and intelligence to win the support of French and British politicians, but also how his vanity and braggadocio displayed no sense of operational security. By the opening of the campaign, his plan was an open secret and he had lost the ability to critically assess the operation as it developed. The result was disaster.
