Gen. William "Billy" Mitchell was an Army officer at the beginning of the 1900s who campaigned for a separate Air Force that would revolutionize warfare. While most of his predictions about American airpower ultimately came true, Mitchell was dismissed as a radical in his day and convicted of insubordination.
The Ostfriesland was hit with armor piercing, 2,000-pound bombs specially designed for use against naval ships. Unfortunately, the Navy claimed that Mitchell overstepped the parameters of the test and Congress just ignored the results.
The friction between Mitchell and the Navy and Congress grew, until two major accidents by the Navy. In one, three planes flying from the West Coast to Hawaii were lost and in another the USS Shenandoah Airship was destroyed with the loss of 14 sailors.
Mitchell took to the press to blast the Navy and Army brass who he believed had failed their subordinates.
"These incidents are the direct result of the incompetency, criminal negligence and almost treasonable administration of the national defense by the Navy and War Departments," Mitchell said. "The bodies of my former companions in the air moulder under the soil in America, and Asia, Europe and Africa, many, yes a great many, sent there directly by official stupidity."
Mitchell was quickly brought up on Article 96 of the Articles of War which prohibits "all disorders and neglects to the prejudice of good order and discipline."
His trial was a national sensation, attended by societal elite and crowds of veterans. Mitchell's lawyer tried to argue that Mitchell's freedom of speech trumped his duties as an officer, but the defense easily ripped through the argument by pointing out allowing complete freedom of speech in the military could create anarchy.
Mitchell was sentenced to five years suspension without pay or duty, during which time he could not accept civilian employment. When the decision reached President Calvin Coolidge, Coolidge amended them to allow the general half pay and a subsistence allowance.
Mitchell opted to resign his commission instead. He launched a speaking tour that traveled around the country and promoted air power.
He died in 1936 and so was not able to see his prophecies come true in World War II. The Air Force Association tried to get his conviction overturned in 1955, but the secretary of the Air Force left it in place because Mitchell did commit the crimes. President Harry S. Truman authorized a special posthumous award for Mitchell in 1946, recognizing Mitchell's work to create modern military aviation.
