Nivelle Offensive & French Army Mutinies

In April 1917 General Robert Nivelle launched a large French offensive on the Chemin des Dames, promising a breakthrough that would rupture the German front. The attack gained some ground but failed to deliver the rapid success expected, while casualties were severe. The gap between confident promises and battlefield reality deepened exhaustion in an army that had already endured years of attritional warfare.

Refusals of orders and collective indiscipline spread through numerous French units during the following weeks. The disturbances did not amount to an attempt to abandon the war or overthrow the government, but they forced changes in command, discipline, leave and offensive policy. Philippe Pétain replaced Nivelle and worked to restore confidence while limiting large-scale attacks until conditions improved.

Alan Bardos’s Enemies and Allies uses the Nivelle crisis alongside intelligence operations and the Mata Hari affair to show how military failure threatened the cohesion of the Allied war effort.
