General Albert Sidney Johnston, after his retreat from Nashville, consequent upon the fall of Fort Donelson, paused at Murfreesboro', Tennessee, for a sufficient period to receive accessions to his force, which increased it to the neighborhood of twenty thousand men. These accessions were portions of the command lately operating in South-eastern Kentucky, and remnants of the forces lately defending Fort Donelson. General Beauregard, having evacuated Columbus, which, in common with the other posts of the former Confederate line of defense in Kentucky and Tennessee, became untenable with the loss of the Tennessee and Cumberland Rivers, concentrated his forces at Corinth, in the northern part of Mississippi. The evacuation of Columbus did not necessarily give the enemy control of the Mississippi above Memphis. A strong position was taken by the Confederate forces at Island No. 10, forty-five miles below Columbus. Considerable anticipation was indulged by the Southern public, of a successful stand at this point for the control of the Mississippi. It was, however, captured by the enemy; and in the loss of two thousand men and important material of war by its surrender, the Confederacy sustained another severe blow, and the Federal Secretary of the Navy justly congratulated the North, upon a "triumph not the less appreciated because it was protracted and finally bloodless." The retirement of the forces of General Albert Sidney Johnston south of the Tennessee River, and the location of General Beauregard's command at Corinth, readily suggested the practicability of a coöperation, by those two commanders, for the defense of the valley of the Mississippi, and the extensive railroad system, of which Corinth is the centre. With the approbation of President Davis, a concentration of troops, from various quarters, ensued, and, about the first of April, an admirable army of forty thousand men was assembled in the neighborhood of Corinth, and upon the railroads leading to that point. There was no situation during the war more assuring of good fortune to the Confederates, than that presented in Northern Mississippi in the early days of April, 1862. President Davis indulged the highest anticipations from this grand combination of forces which he so cordially approved. He confidently expected a victory from the Western army, led by that officer whose capacity he trusted above all others, which should more than compensate for the heavy losses of the previous campaign. General Johnston was no less hopeful of the situation. The conjuncture was indeed rare in its opportunities. The exposed situation of General Grant, whose command lay upon the west bank of the Tennessee River, with a most remarkable want of appreciation of its precarious position by its commander, and a total absence of provision for its safety, invited an immediate attack by the Confederate commander, before the Federal column could be reinforced by Buell, then making rapid
