Nivelle promised a swift decisive breakthrough and publicised his plans widely, alarming some colleagues. The Germans learned elements of the offensive beforehand, reducing any prospect of surprise.

Premature publicity and inadequate operational secrecy.

Despite objections from Pétain, Lyautey and other commanders about readiness and risks, Nivelle pursued the major offensive scheduled for 16 April. His decision later became a central criticism of his leadership.

Disregarding warnings before a high-risk offensive.

The Chemin des Dames attack failed to break through German positions and caused heavy casualties. Nivelle did not honour his promise to halt without a breakthrough within forty-eight hours, and fighting resumed after a pause.

State of the evidence

Failure, continuation and casualties documented; numerical estimates vary.

No known personal criminal proceeding.

Continuing an unsuccessful offensive beyond the promised limit.

The failed offensive helped trigger refusals to attack and mutinies in parts of the French Army. Historians also identify deeper causes including earlier losses, exhaustion and insufficient leave.

State of the evidence

Historical link established between offensive failure and morale crisis.
