About the author

Born in Ottawa, Illinois, in 1853, Arthur Lockwood Wagner graduated from West Point and served in the infantry during campaigns against Native nations in the American West. He later became known less for battlefield fame than for the force of his ideas, building a reputation as a serious student of tactics and military education.

Wagner taught at Fort Leavenworth and was widely respected as a military instructor and writer. His books on tactics, security, and information were important professional texts for American officers, and later historians have described him as a key figure in the reform of the U.S. Army before the twentieth century’s major wars.

He also served in staff roles during the Philippine-American War and was among the early officers connected with the Army’s developing General Staff and War College system. He died in 1905, but his influence lasted through the officers he trained and the more modern, study-driven army he helped encourage.
