As Secretary of War, Baker presided over the American military participation in the World War I in 1917 and 1918, including the creation of a nationwide military draft. Baker selected Gen. John J. Pershing to head the American Expeditionary Forces. At Baker's insistence, Wilson made the American forces an independent fighting partner of the Allies against the Central Powers, rather than letting American troops be used to replenish British and French forces as those nations advised. At one meeting with British Prime Minister, David Lloyd George, Baker told him that "if we want advice as to who should command our armies, we would ask for it. But until then we do not want nor need it from anyone, least of all you."
