Marshall opposed any higher grade, saying he did not need one. King and Secretary of War Henry L. Stimson both suspected that as Pershing's longtime protégé, Marshall would resist any rank equivalent to General of the Armies while his mentor was still alive. Stimson did ask President Franklin D. Roosevelt to appoint Marshall as General of the Armies in September 1943 so he could command the planned invasion of France while remaining chief of staff, but Roosevelt ultimately gave the command to Dwight D. Eisenhower instead.
