French Army Mutinies (1917)

The French Army mutinies of 1917 took place amongst the French troops on the Western Front in Northern France during World War I. They started just after the disastrous Second Battle of the Aisne, the main action in the Nivelle Offensive in April 1917. General Robert Nivelle had promised a decisive war-ending victory over the Germans in 48 hours; the men were euphoric on entering the battle. The shock of failure soured their mood overnight. The mutinies and associated disruptions involved, to various degrees, nearly half of the French infantry divisions stationed on the western front. The new commander, General Philippe Pétain, restored morale by talking to the men, promising no more suicidal attacks, providing rest for exhausted units, home furloughs, and moderate discipline. He held 3,400 courts martial; 554 mutineers were sentenced to death but over 90% had their sentences reprieved. The mutinies were kept secret from the Germans and their full extent was not revealed until decades later.

The immediate cause was the extreme optimism and subsequent disappointment at the Nivelle offensive in the spring of 1917. Other causes were pacificism, stimulated by the Russian Revolution and the trade-union movement, and disappointment at the non-arrival of American troops.

Nearly one million French soldiers (306,000 in 1914; 334,000 in 1915; 217,000 in 1916; 121,000 in early 1917,) out of a population of twenty million French males of all ages, had been killed in fighting by early 1917. These losses had deadened the French will to attack. In April 1917, French General Robert Nivelle promised a war-winning decisive victory. He proposed to work closely with the British Army to break through the German lines on the Western Front with a great attack against the German occupied Chemin des Dames, a long and prominent ridge running east to west just north of the Aisne River. For this General Nivelle applied a tactic which he had already inaugurated with success at Verdun in October 1916,: a creeping barrage, in which French artillery fired its shells to land just in front of the advancing infantry. This was designed to suppress the defending German troops in their trenches right up to the moment when the attackers closed in on them.
