A career officer who attained the rank of colonel (1852) and served as adjutant general of the U.S. Army, Samuel Cooper forged a close friendship with Jefferson Davis during the latter’s tenure as U.S. secretary of war. In March 1861, Cooper resigned his commission and offered his services to the Confederacy and to its new president, Davis, who appointed him adjutant and inspector general of the Confederate army. Greatly prized for his administrative abilities, Cooper became the Confederacy’s highest-ranking army officer. When the Civil War ended, he ensured the preservation of Confederate War Department records by turning them over to federal authorities.
