Ferdinand Foch (2 October 1851 - 20 March 1929) was a French soldier, military theorist, and writer. A veteran of the Franco-Prussian War, Foch published a series of analyses on French tactics. He served as a general in the French Army during World War I. In 1918, he was made Marshal of France. A few months later, he was made Supreme Allied commander. He accepted Germany's call for peace in November 1918. After the Treaty of Versailles, Foch stated that it would merely be "an armistice for 20 years."
