Gamelin was appointed Supreme Commander of the French Armed Forces at the outbreak of World War II. He was responsible for implementing the Dyle Plan, which committed the main French forces to Belgium in response to a German invasion.

German forces invaded France through the Ardennes, bypassing the Maginot Line. Gamelin's command structure failed to respond effectively to the German breakthrough at Sedan. The French army was encircled and forced into retreat, leading to the fall of France.

On May 19, 1940, French Prime Minister Paul Reynaud dismissed Gamelin for his failure to stop the German offensive. He was replaced by Maxime Weygand. Gamelin was later arrested by the Vichy regime and tried at the Riom Trial.
