Maurice Gamelin

Maurice Gamelin was a senior French Army officer who served as the Chief of the Army Staff and, ultimately, as the Supreme Commander of the Allied Armies during the opening phase of the Second World War. His strategic planning and command decisions during the Battle of France in 1940 are widely considered to have been catastrophic failures, leading to a swift and decisive German victory and his own dismissal. Gamelin's career, which had been distinguished during the First World War, ended in ignominy, and he became a central figure in the Riom Trial, a Vichy-sponsored attempt to assign blame for the French defeat.

Early life and military career

Born in Paris in 1872, he graduated from the prestigious École Spéciale Militaire de Saint-Cyr in 1893, joining the French colonial infantry. His early service included a posting with the French military mission to Brazil, where he honed his staff skills. Gamelin's intellectual prowess and political acumen were noted early, leading to an appointment to the École Supérieure de Guerre, the French war college. He served as an aide to General Joseph Joffre before the outbreak of the First World War, a connection that would prove highly influential for his future advancement within the French Army hierarchy.

World War I and interwar period

During the First World War, he served with distinction on Joffre's staff at French General Headquarters during critical battles like the First Battle of the Marne and the Battle of Verdun. Promoted to brigadier general in 1916, he later commanded a division with success. In the interwar period, his career progressed steadily; he commanded the 20th Army Corps and served as Chief of the Army Staff from 1931. Gamelin was a key figure in overseeing the construction of the Maginot Line and modernizing the army, though his advocacy for a defensive doctrine and his underestimation of armored warfare tactics later proved fatal.

Supreme Commander of the French Army

Appointed Chief of the Defence Staff in 1938 and then Supreme Commander of the French and Allied forces at the start of the Second World War, Gamelin commanded from his static headquarters at the Château de Vincennes. He orchestrated the initial, abortive Saar Offensive and was the principal architect of the Dyle Plan, which committed the best Allied mobile forces, including the British Expeditionary Force and the French First Army, to advance into Belgium. His command style was detached and bureaucratic, with poor communications to front-line commanders like General Alphonse Georges.

Battle of France and downfall

The execution of the Dyle Plan played directly into German hands during the Battle of France in May 1940. Gamelin had fatally left the Ardennes forest lightly defended, considering it impassable for major forces. The decisive German thrust through the Ardennes, culminating in the breakthrough at Sedan, outflanked the Maginot Line and trapped the Allied armies in the north. His only significant countermove, ordering a attack on the vulnerable German corridor, was too little, too late. On May 19, 1940, he was relieved of command by Prime Minister Paul Reynaud and replaced by General Maxime Weygand.

Later life and legacy

After the Armistice of 22 June 1940, he was arrested by the Vichy government and became the lead defendant in the Riom Trial, accused of responsibility for the defeat. The trial was largely a political spectacle and was suspended in 1942. He was later imprisoned by the Germans in the Buchenwald concentration camp and then the Itter Castle, where he was freed by American troops in 1945. He spent his final years writing memoirs, dying in Paris in 1958. Gamelin's legacy is that of a capable staff officer whose rigid, defensive mindset and failure to grasp the pace of modern warfare contributed significantly to one of the most stunning military defeats in modern history, the Fall of France.
