It was deemed, however, more important, at that time, to occupy and fortify Columbus, in Kentucky, situated on the Mississippi river, some twenty-two miles below the mouth of the Ohio. This measure, it was thought, would protect the States lying along the Mississippi from invasion, by enabling the Confederates to hold the river, as it was by the river, only, that those States could be conveniently reached. General Pillow's forces were consequently ordered to that point. Finding that his plans were rendered impossible of execution, on account of the want of General Pillow's co-operation, Hardee returned to Pocahontas, and was shortly afterward transferred, with the greater portion of the troops under his command, to the eastern side of the river, and was ordered to Bowlinggreen as soon as that place was occupied. Up to the date of General Johnston's taking command, the chief difficulty in the way of action and decisive operations in the West (independently of the inferior number and miserable equipment of the troops) was the lack of uniformity and concert in the plans and operations of the various commanders. There was no one in supreme military control from whom the subordinate Generals could receive definite instructions, and orders which they felt obliged to obey. While an immense extent of country was included in one Department, and theoretically under one chief, yet practically every officer, no matter what was the strength or nature of his command, who happened not to be troubled with a senior immediately at his elbow, planned and acted for himself and with a perfect indifference to the operations of every one else. The President and Secretary of War were too distant to do any good, if such interference ever does any good, and a ruling mind was needed at the theater of events. It is true that General Polk, whose headquarters were at Memphis, was senior to the others, he being a Major-General, and all the rest but Brigadiers, and he was ostensibly in chief command and directed to a certain extent, the movements of all.
But, whether it was that, in a period when nothing was fairly organized, his authority was not clearly defined, or that he felt some hesitation in vigorously exercising it, it is certain that each of the Generals, who have been here mentioned, acted as if he knew himself to be, to all intents and purposes, in independent command.
This evil was completely remedied by the appointment to the chief command in the West of General Johnson, and the prompt and decided measures which he instituted. General Johnson's whole life had been one of the most thorough military training, and no officer of his years in the old army of the United States had seen more service; but more than that, he was a soldier by instinct, and Nature had intended him for military command.
He felt the full importance of careful preparation, and the establishment by order and system in every branch and department of the service. No martinet of the schools was ever more alive to the necessity of rigid method and exact discipline, for he knew that without their inauguration and strict observance, it would be impossible to even partially discharge the duties of his vast commission. But he also saw clearly the vital necessity of maintaining in tact the spirit which animated the men of his army, and which had summoned them into the field. He knew that to impair the ardor which had induced them to become soldiers was to destroy their morale; that to attempt to make them machines would result in making them worthless.
Although the troops at his disposal seriously needed instruction and more perfect organization, he did not waste precious moments in seeking to impart them then. He did not permit the high spirit of his gallant army to sink into lethargy, nor the interest which the people felt in the conduct of military affairs to abate by remaining inactive, and in a position which would reduce him, under all circumstances, to the defensive. A concentration of his forces any where upon the Tennessee border would not only have placed him at great strategic disadvantage, but would have been instantly accepted by the soldiery and the people as a signal of his intention to await the pleasure and movements of his adversary. Almost immediately after his arrival at Nashville, the troops which had collected at Camp Boone, the rendezvous of the Kentucky regiments, and the Tennessee troops which were available, were pushed into Kentucky. Kentucky's neutrality, for a time recognized provisionally, and so far as a discreet silence upon the subject amounted to recognition by the Federal Government, had already been exploded. The Government of the United States, having made the necessary preparations, was not disposed to abandon a line of invasion which led right to the vitals of the Confederacy, and promised a successful reduction of the rebellion in at least three of the seceded States, because of the partially rebellious attitude assumed by Kentucky.
Camp Dick Robinson had been organized and put into successful operation in July. General Anderson took command at Louisville on the 20th of September. The other portions of the state were occupied, and definite lines were established by the opposing forces, nearly about the same time. General Johnson advanced as far as Green river, making it his line of defense for his center, while his right rested on the Cumberland and the rugged ranges of its hills. His line might be said to extend from Columbus through Hopkinsville, Munfordsville and Somerset to the Virginia border somewhere in the vicinity of Pound Gap. The Federal forces were pushed down, almost simultaneously with General Johnson's advance to Green river, to Elizabethtown, and in a few days afterward to Nolin creek. Their line may be described as running almost directly from Paducah in the West, to Prestonburg in the East. This line gave them possession of the mouths of the Tennessee, Cumberland and Green rivers, of the Blue grass region, and of a greater share of the central and eastern portions of the State.
A single glance at the map will show the importance of Bowlinggreen as a strategic point. It will be seen that it is admirably adapted for a base of operations, offensive or defensive, in such a campaign as General Johnson was about to inaugurate at the time of its occupation. Situated upon the bank of the Barren river, it has that river and the Green river to protect it against attack from the front. The Barren river empties into the Green some twenty miles from and northwest of Bowlinggreen, and the Green flowing in a northwesterly direction, affords an admirable line of defense for many miles to the left. There are few fords and ferries of Green river after its junction with the Barren, and those which it has can be easily held. The danger of attack from the extreme left flank was guarded against, but as the result showed imperfectly, by Forts Henry and Donelson constructed respectively upon the Tennessee and Cumberland rivers. The one just upon, the other about ten miles from, the Kentucky and Tennessee border. As there was little danger to be apprehended in that direction, except from forces brought up those rivers and established in the rear of Bowlinggreen, these forts, whose strength was overrated, were thought to sufficiently protect that flank. The Cumberland river rising, in the mountains of Southeastern Kentucky, flows nearly due East and West and upon the same parallel of latitude on which Bowlinggreen is situated, until within sixty or seventy miles of that place, when it inclines to the Southwest. The Green river affords a line extending eastward, and defensible, beyond the point where the Cumberland begins to bend to the Southwest. At this point the two rivers are about thirty miles apart. The country throughout this section of the State is broken but accessible to the march of large bodies of troops. It is apparent, however, that an army, with Bowlinggreen for its base, unless immensely outnumbered, would have it in its power to take advantage of an opponent advancing upon Bowlinggreen by that route. Even if pressed in front, it could hold the river with detachments until with the bulk of its strength it struck the enemy coming from the East.
The line of march of the latter would render its communications, and concert of action with its friends, very difficult, and liable at any time to be entirely destroyed; while the General upon the defensive, if vigilant and active, could know the movements of both advancing columns, and attack either, with the mass of his army, when he pleased. Moreover, in the disposition of the Confederate forces, General Zollicoffer with some two or three thousand men, was stationed at Monticello, about ninety-five miles from Bowlinggreen, and a little to the south of east. Monticello is twenty-one miles from the Cumberland; all the neighboring fords were in Zollicoffer's possession, and his scouts explored the country for some distance beyond the river. It is plain that any hostile force moving upon Bowlinggreen by this eastern flank would have exposed itself to attack by Zollicoffer.
