With reports swirling that retired Marine Gen. James Mattis is a leading contender to be selected as Secretary of Defense for President-elect Donald Trump, some people think it would be unprecedented for a former general to serve as Pentagon chief.
But General of the Army George C. Marshall might have something to say about that.
Marshall is perhaps best known for the "Marshall Plan" he put together as Secretary of State under President Harry S Truman to help rebuild Europe after World War II. Marshall had served two years in that post before leaving to become president of the American Red Cross.
But when the Korean War started in June 1950 and became a near-disaster, Truman fired then-Secretary of Defense Louis A. Johnson over the military's lack of readiness. He then nominated Marshall to take over.
Marshall was technically prohibited from serving as Secretary of Defense. As a General of the Army, he was by law on active duty, and per 10 USC 113, nobody who was a commissioned officer can serve as Secretary of Defense without having been retired for seven years.
Congress, though, waived that provision to allow Marshall to serve.
Marshall spent a year in the Pentagon, not only working to get the military into fighting shape for the Korean War, but also rebuilding bridges that his predecessor had burned with the Joint Chiefs of Staff (particularly the Navy), and also with the State Department.
Within two months of Marshall becoming SecDef, the United States and allied forces had nearly reached the Yalu River in Korea. When the Chinese Communists intervened and pushed the allied forces back, Marshall would play a crucial role in President Truman's decision to relieve General of the Army Douglas MacArthur as overall commander in Korea, despite his initial reluctance to see that happen.
Within a year, Marshall resigned as Secretary of Defense and was succeeded by his deputy, Roger A. Lovett. He would die eight years after leaving the Pentagon.
Famous for has program to save a war ravaged Europe, Marshall's service as Secretary of Defense is a nearly-forgotten footnote in his long career.
