Shiloh is not distinguished by outstanding generalship on either side, but it is interesting as a battle fought by raw volunteers—young men without previous experience in a major engagement and with little or no military training. _Preliminary Campaign_ War activity west of the Appalachian Mountains in 1861 was confined chiefly to the States of Kentucky and Missouri. Toward the end of the year when loyalty, or at least the neutrality, of the governments of these border States seemed assured, the Federals began making plans for the invasion of the South by way of the western rivers and railroads. Each side began to maneuver for strategic positions. The Confederate General, Leonidas Polk, believing that the Southern States were about to be invaded through Kentucky, moved up quickly from his position at Union City, Tenn., and seized Columbus, Ky., the northern terminus of the Mobile and Ohio Railroad. Gen. Ulysses S. Grant, recently appointed commander of the Federal troops in and around Cairo, Ill., had made preparations to occupy that important river port and railway center on the following day. Thwarted at Columbus, Grant retaliated by taking Paducah, Ky., located at the junction of the Tennessee and Ohio Rivers. It now became apparent to the Confederate high command in Richmond that a strong line would have to be established along the northwestern border of the Confederacy before the Union armies had time to occupy more of the strategic points. They believed that the task could be performed more effectively if all troops in that theater of operation were placed under one commander. Accordingly, Confederate President Jefferson Davis sent Gen. Albert Sidney Johnston to the West with the imposing title of “General Commanding the Western Department of the Army of the Confederate States of America.” Arriving in Nashville on September 14, 1861, General Johnston studied his difficult assignment. The line he was supposed to occupy extended from the mountains of eastern Tennessee westward across the Mississippi to the Kansas boundary. Only two points on the proposed line were then in Confederate hands: Columbus, which he considered the natural key to the Confederate defense of the Mississippi, and Cumberland Gap, Ky., which he had previously ordered Gen. Felix K. Zollicoffer to occupy. One of Johnston’s first official acts upon arriving at Nashville was to order Gen. Simon B. Buckner to secure Bowling Green, Ky., one of the most important railroad centers south of the Ohio. He also ordered garrisons to the incomplete works at Fort Henry, on the Tennessee, and Fort Donelson, on the Cumberland, hoping to prevent a Union advance up either of these natural highways. A Federal offensive up the Tennessee or the Cumberland would endanger the important railroad and industrial center of Nashville, Tenn.
