5. 5 Mitchell’s Last Campaign  1922 - 1924 -- Mitchell concentrated on developing doctrine advocated strategic bombardment  1925 -- Demoted to Colonel because of his unrelenting bid for a separate air force  After the crash of the dirigible, “Shenandoah,” he accused military leaders of “incompetence and criminal negligence”  Court-martial -- October 25, 1925

6. 6 Mitchell’s Legacy  Focused attention on airpower  Forced people to accept the potential of airpower  Mentored many aviators who would carry on his work -- some became instructors at the Air Corps Tactical School (ACTS)
