Again, the aid our forces would receive from the loyal men in Tennessee would enable them soon to crush the last traitor in that region, and the _separation of the two extremes_ would do more than one hundred battles for the Union cause. The Tennessee River is crossed by the Memphis and Louisville Railroad, and the Memphis and Nashville Railroad. At Hamburg the river makes the big bend on the east, touching the north-east corner of Mississippi, entering the north-west corner of Alabama, forming an arc to the south, entering the State of Tennessee at the north-east corner of Alabama, and if it does not touch the north-west corner of Georgia, comes very near it. It is but eight miles from Hamburg to the Memphis and Charleston Railroad, which goes through Tuscumbia, only two miles from the river, which it crosses at Decatur thirty miles above, intersecting with the Nashville and Chattanooga road at Stephenson. The Tennessee never has less than three feet to Hamburg on the "shoalest" bar, and during the fall, winter, and spring months, there is always water for the largest boats that are used on the Mississippi River. It follows, from the above facts, that in making the Mississippi the key to the war in the West, or rather in overlooking the Tennessee River, the subject is not understood by the superiors in command. The War Department looked over these papers, and Col. Scott, the Assistant Secretary, possessing a knowledge of the railroad facilities and connections of the South, unequaled perhaps by any other man in the country at that time, at once saw the vital importance of Miss Carroll's plan. He declared it to be the first clear solution of the difficult problem, and was soon sent West to assist in carrying it out in detail. The Mississippi expedition was abandoned, and the Tennessee made the point of attack. Both land and naval forces were ordered to mass themselves at this point, and the country soon began to feel the wisdom of this movement. The capture of Fort Henry, an important Confederate post on the Tennessee River serving to defend the railroad communication between Memphis and Bowling Green, was the first result of Miss Carroll's plan. It fell Feb. 6, 1862, and was rapidly followed by the capture of Fort Donelson, which, after a gallant defense, surrendered to the Union forces Feb. 16th, and the name of Ulysses S. Grant, as the general commanding these forces, for the first time became known to the American people. By these victories the line of Confederate fortifications was broken, and the enemy's means of communication between the East and the West were destroyed.
