From the training field at West Point to the entrenchments at Fort Donelson, Charles Ferguson Smith was the soldier's soldier. During his nearly forty-two year career, General Smith was a teacher, mentor, and role model for many young officers who became prominent Civil War generals. He was respected and admired by his former students and future officers including Grant, Halleck, Longstreet, and Sherman. This long overdue biography reveals a man who was a faithful officer, an excellent disciplinarian, an able commander, and a modest gentleman. Smith served at the US Military Academy from 1829 to 1842 as Instructor of Tactics, Adjutant to the Superintendent, and Commandant of Cadets. However, he was more than a instructor training cadets in the art of war. He set an example to junior officers in the Mexican War leading his light battalion to victories and earning three field promotions. Smith served with Albert Johnston and other future Confederate officers in the Mormon War. He mentored Grant while serving under him in the Civil War. Smith rose to the rank of major general while refusing to solicit political favours and court journalists. He ""turned the tide"" at Fort Donelson which led to Grant's rise to fame.

The US Military Academy trained officers for both sides in the American Civil War. The Commandant of Cadets played an important role in this education by overseeing the Corps of Cadets' drills and tactical instruction. Historians criticize the tactical program as antiquated because it did not consider the impact of rifled weapons, the unique American terrain, and suitability of Napoleonic tactics and strategy. Much of this blame is due to confusion between strategy and tactics and differences between minor tactics and grand tactics. The Army assigned sixteen officers as commandants between 1817 to 1864. Their impact on cadets and tactical education varied based on the amount of time as commandant and their attitude about the assignment. These commandants made changes to the program, developed new textbooks, and taught many cadets who became Civil War generals. Historians have generally ignored the roles of the commandants despite their major influence on cadets. Readers who want a better understanding of antebellum military training will appreciate discussions about preparing cadets to become officers. The biographies of the forgotten men who influenced future officers present an account of the commandant's contributions to the Academy, notable graduates, and other military service.
