Mark Eickhoff is currently a part-time graduate student and a full-time civilian human resources specialist with a Department of Defense agency in Indianapolis, Indiana. He has a B.A. in History and International Studies from Wayne State College in Wayne, Nebraska, and is a graduate of the U.S. Air Force Squadron Officer School and the Air Command and Staff College. In his thesis, Mark examines the life and career of MG Charles D. Rhodes, a U.S. Army cavalry officer who served between 1889-1929 and was an active participant in the Pine Ridge campaign against the Sioux, the Spanish-American War, the Boxer Rebellion, the Philippine War, and World War I. An accomplished military historian and intellectual in his own right, Rhodes was an early mentor to George S. Patton and an important figure in the Army's early 20th century transformation. Mark tests and applies historian Brian McAllister Linn's American way of war theory in analyzing Rhodes' published works and personal diary to determine whether Rhodes fits within any of the military traditions of the Linn model, how Rhodes' writing reflected that tradition, and Rhodes' subsequent contributions to developing the American way of war.
