Marshal Ferdinand Jean Marie Foch was a French general and military theorist who served as the Supreme Allied Commander during the First World War. An aggressive, even reckless commander at the First Marne, Flanders, and Artois campaigns of 1914–1916, Foch became the Allied Commander-in-Chief in 1918 and successfully coordinated the French, British, American, and Italian efforts into a coherent whole, deftly handling his strategic reserves. In November 1918, Marshal Foch accepted the German cessation of hostilities and was present at the armistice of 11 November.
