Eisenhower's General-of-the-Army insignia. It was worn on epaulet of his uniform. The maker's mark stamped on the back is "Luxemburg, Sterling." On December 16, 1944, as the German army launched a counter offensive in the Ardennes Forest of Belgium and Luxemburg, Eisenhower was informed that he was to be promoted to a five-star general. His official rank would be General-of-the-Army. The other three Americans to hold that rank in World War II included George C. Marshall, who served as Chief of Staff, Douglas MacArthur in the Pacific Theater, and Henry "Hap"� Arnold, commander of the U.S. Army Air Forces.
