Smith's troops were returned the same day. The enemy were trying to get away from Nashville and not to return to it.

At this time General Albert Sidney Johnston commanded all the Confederate troops west of the Alleghany Mountains, with the exception of those in the extreme south. On the National side the forces confronting him were divided into, at first three, then four separate departments. Johnston had greatly the advantage in having supreme command over all troops that could possibly be brought to bear upon one point, while the forces similarly situated on the National side, divided into independent commands, could not be brought into harmonious action except by orders from Washington.

At the beginning of 1862 Johnston's troops east of the Mississippi occupied a line extending from Columbus, on his left, to Mill Springs, on his right. As we have seen, Columbus, both banks of the Tennessee River, the west bank of the Cumberland and Bowling Green, all were strongly fortified. Mill Springs was intrenched. The National troops occupied no territory south of the Ohio, except three small garrisons along its bank and a force thrown out from Louisville to confront that at Bowling Green. Johnston's strength was no doubt numerically inferior to that of the National troops; but this was compensated for by the advantage of being sole commander of all the Confederate forces at the West, and of operating in a country where his friends would take care of his rear without any detail of soldiers. But when General George H. Thomas moved upon the enemy at Mill Springs and totally routed him, inflicting a loss of some 300 killed and wounded, and forts Henry and Heiman fell into the hands of the National forces, with their armaments and about 100 prisoners, those losses seemed to dishearten the Confederate commander so much that he immediately commenced a retreat from Bowling Green on Nashville. He reached this latter place on the 14th of February, while Donelson was still besieged. Buell followed with a portion of the Army of the Ohio, but he had to march and did not reach the east bank of the Cumberland opposite Nashville until the 24th of the month, and then with only one division of his army.

The bridge at Nashville had been destroyed and all boats removed or disabled, so that a small garrison could have held the place against any National troops that could have been brought against it within ten days after the arrival of the force from Bowling Green. Johnston seemed to lie quietly at Nashville to await the result at Fort Donelson, on which he had staked the possession of most of the territory embraced in the States of Kentucky and Tennessee. It is true, the two generals senior in rank at Fort Donelson were sending him encouraging dispatches, even claiming great Confederate victories up to the night of the 16th when they must have been preparing for their individual escape. Johnston made a fatal mistake in intrusting so important a command to Floyd, who he must have known was no soldier even if he possessed the elements of one. Pillow's presence as second was also a mistake. If these officers had been forced upon him and designated for that particular command, then he should have left Nashville with a small garrison under a trusty officer, and with the remainder of his force gone to Donelson himself. If he had been captured the result could not have been worse than it was.

Johnston's heart failed him upon the first advance of National troops. He wrote to Richmond on the 8th of February, "I think the gunboats of the enemy will probably take Fort Donelson without the necessity of employing their land force in cooperation." After the fall of that place he abandoned Nashville and Chattanooga without an effort to save either, and fell back into northern Mississippi, where, six weeks later, he was destined to end his career.

From the time of leaving Cairo I was singularly unfortunate in not receiving dispatches from General Halleck. The order of the 10th of February directing me to fortify Fort Henry strongly, particularly to the land side, and saying that intrenching tools had been sent for that purpose, reached me after Donelson was invested. I received nothing direct which indicated that the department commander knew we were in possession of Donelson. I was reporting regularly to the chief of staff, who had been sent to Cairo, soon after the troops left there, to receive all reports from the front and to telegraph the substance to the St. Louis headquarters. Cairo was at the southern end of the telegraph wire. Another line was started at once from Cairo to Paducah and Smithland, at the mouths of the Tennessee and Cumberland respectively. My dispatches were all sent to Cairo by boat, but many of those addressed to me were sent to the operator at the end of the advancing wire and he failed to forward them. This operator afterwards proved to be a rebel; he deserted his post after a short time and went south taking his dispatches with him. A telegram from General McClellan to me of February 16th, the day of the surrender, directing me to report in full the situation, was not received at my headquarters until the 3d of March.

On the 2d of March I received orders dated March 1st to move my command back to Fort Henry, leaving only a small garrison at Donelson. From Fort Henry expeditions were to be sent against Eastport, Mississippi, and Paris, Tennessee. We started from Donelson on the 4th, and the same day I was back on the Tennessee River. On March 4th I also received the following dispatch from General Halleck:

MAJ.-GEN. U. S. GRANT,
Fort Henry:

You will place Maj.-Gen. C. F. Smith in command of expedition, and remain yourself at Fort Henry. Why do you not obey my orders to report strength and positions of your command?

H. W. HALLECK,
Major-General.

I was surprised. This was the first intimation I had received that General Halleck had called for information as to the strength of my command. On the 6th he wrote to me again. "Your going to Nashville without authority, and when your presence with your troops was of the utmost importance, was a matter of very serious complaint at Washington, so much so that I was advised to arrest you on your return." This was the first I knew of his objecting to my going to Nashville. That place was not beyond the limits of my command, which, it had been expressly declared in orders, were "not defined." Nashville is west of the Cumberland River, and I had sent troops that had reported to me for duty to occupy the place. I turned over the command as directed and then replied to General Halleck courteously, but asked to be relieved from further duty under him.

Later I learned that General Halleck had been calling lustily for more troops, promising that he would do something important if he could only be sufficiently reinforced. McClellan asked him what force he then had. Halleck telegraphed me to supply the information so far as my command was concerned, but I received none of his dispatches. At last Halleck reported to Washington that he had repeatedly ordered me to give the strength of my force, but could get nothing out of me; that I had gone to Nashville, beyond the limits of my command, without his authority, and that my army was more demoralized by victory than the army at Bull Run had been by defeat. General McClellan, on this information, ordered that I should be relieved from duty and that an investigation should be made into any charges against me. He even authorized my arrest. Thus in less than two weeks after the victory at Donelson, the two leading generals in the army were in correspondence as to what disposition should be made of me, and in less than three weeks I was virtually in arrest and without a command.
