The arrival of General Johnston in Richmond, early in September, was a source of peculiar congratulation to President Davis. Between these illustrious men had existed, for many years, an endearment, born of close association, common trials and triumphs, and mutual confidence, which rendered most auspicious their coöperation in the cause of Southern independence. "Albert Sidney Johnston," says Professor Bledsoe, in a recent publication, "who, take him all in all, was the simplest, bravest, grandest man we have ever known, once said to the present writer: 'There is no measuring such a man as Davis;' and this high tribute had a fitting counterpart in that which Davis paid Johnston, when discussing, in the Federal Senate, the Utah expedition. Said he ... 'I hold that the country is indebted to the administration for having selected the man who is at the head of the expedition; who, as a soldier, has not a superior in the army or out of it; and whose judgment, whose art, whose knowledge is equal to this or any other emergency; a man of such decision, such resolution that his country's honor can never be tarnished in his hands; a man of such calmness, such kindness, that a deluded people can never suffer by harshness from him.'" President Davis immediately tendered to General Johnston the command of one of the two grand military divisions of the Confederacy, and he as promptly repaired to the scene of his duties. The general features of General Johnston's policy contemplated a line of defense running from the Mississippi through the region immediately covering Nashville to Cumberland Gap--the key to the defense of East Tennessee and South-western Virginia, and thus to the most vital line of communication in the South. It is easy to conceive the large force requisite for so important and difficult a task, against the immense armies of Grant and Buell, numbering, in the aggregate, more than one hundred thousand men. Despite the earnest appeals of General Johnston, and notwithstanding that upon the successful maintenance of his position depended the successful defense of the entire southern and south-western sections of the Confederacy, his force, at the last of January, 1862, did not exceed twenty-six thousand men. Informed of his perilous situation, the Confederate Government could do no more than second the appeals and remonstrances of General Johnston. Slight accessions were made to his force from the States which were menaced, but, as results speedily demonstrated, he was unable to meet the enemy with an adequate force at any one of the vital points of his defensive line.
