Ferdinand Foch was a distinguished French general and military theorist who served as the Supreme Allied Commander during the final year of World War I. His strategic thinking and leadership were pivotal in halting the German spring offensive and launching the successful counter-offensives of 1918. Promoted to Marshal of France, he played a principal role in the armistice negotiations and the subsequent peace treaty. Remembered for his unwavering resolve and offensive doctrines, Foch remains one of the most prominent military figures of the 20th century.
