now had principal military responsibility for Kentucky, a border state in which the Confederates held Columbus and Bowling Green, and were also present near the Cumberland Gap. He became exceedingly pessimistic about the outlook for his command and he complained frequently to Washington about shortages, while providing exaggerated estimates of the strength of the rebel forces and requesting inordinate numbers of reinforcements. Critical press reports about Sherman began to appear after the U.S. Secretary of War, Simon Cameron, visited Louisville in October 1861. In early November, Sherman asked to be relieved of his command. He was promptly replaced by Don Carlos Buell and transferred to St. Louis. In December, he was put on leave by Henry W. Halleck, commander of the Department of the Missouri, who found him unfit for duty and sent him to Lancaster, Ohio, to recuperate. While he was at home, his wife Ellen wrote to his brother, Senator John Sherman, seeking advice and complaining of "that melancholy insanity to which your family is subject". In his private correspondence, Sherman later wrote that the concerns of command "broke me down" and admitted to having contemplated suicide. His problems were compounded when the Cincinnati Commercial described him as "insane". By mid-December 1861 Sherman had recovered sufficiently to return to service under Halleck in the Department of the Missouri. In March, Halleck's command was redesignated the Department of the Mississippi and enlarged to unify command in the West. Sherman's initial assignments were rear-echelon commands, first of an instructional barracks near St. Louis and then in command of the District of Cairo. Operating from Paducah, Kentucky, he provided logistical support for the operations of Grant to capture Fort Donelson in February 1862. Grant, the previous commander of the District of Cairo, had just won a major victory at Fort Henry and been given command of the ill-defined District of West Tennessee. Although Sherman was technically the senior officer, he wrote to Grant, "I feel anxious about you as I know the great facilities [the Confederates] have of concentration by means of the River and R[ail] Road, but [I] have faith in you—Command me in any way." Shiloh After Grant captured Fort Donelson, Sherman got his wish to serve under Grant when he was assigned on March 1, 1862, to the Army of West Tennessee as commander of the 5th Division. His first major test under Grant was at the Battle
