Howze's last assignment was to preside over the
court-martial of Colonel
Billy Mitchell, who had made public comments in response to the Navy dirigible crashing in a storm. The crash killed 14 of the crew and Mitchell issued a statement accusing senior leaders in the Army and Navy of incompetence and "almost treasonable administration of the national defense." In November 1925 he was
court-martialed at the direct order of
President Calvin Coolidge. The trial attracted significant interest, and public opinion supported Mitchell. The court found Mitchell guilty of
insubordination, and suspended him from active duty for five years without pay. The generals ruling in the case wrote, "The Court is thus lenient because of the military record of the Accused during the World War." On February 1, 1926, Mitchell resigned in-lieu of accepting the courts punishment. ==Military awards==
