It seemed to be the policy of General Halleck and Secretary Stanton to keep any force sent there, in pursuit of the invading army, moving right and left so as to keep between the enemy and our capital; and, generally speaking, they pursued this policy until all knowledge of the whereabouts of the enemy was lost. They were left, therefore, free to supply themselves with horses, beef cattle, and such provisions as they could carry away from Western Maryland and Pennsylvania. I determined to put a stop to this. I started Sheridan at once for that field of operation, and on the following day sent another division of his cavalry.

I had previously asked to have Sheridan assigned to that command, but Mr. Stanton objected, on the ground that he was too young for so important a command. On the 1st of August when I sent reinforcements for the protection of Washington, I sent the following orders:

CITY POINT, VA.,

August 1, 1864, 11.30 A.M.

MAJOR-GENERAL HALLECK,
Washington D. C.

I am sending General Sheridan for temporary duty whilst the enemy is being expelled from the border. Unless General Hunter is in the field in person, I want Sheridan put in command of all the troops in the field, with instructions to put himself south of the enemy and follow him to the death. Wherever the enemy goes let our troops go also. Once started up the valley they ought to be followed until we get possession of the Virginia Central Railroad. If General Hunter is in the field, give Sheridan direct command of the 6th corps and cavalry division. All the cavalry, I presume, will reach Washington in the course of to-morrow.

U. S. GRANT,
Lieutenant-General.

The President in some way or other got to see this dispatch of mine directing certain instructions to be given to the commanders in the field, operating against Early, and sent me the following very characteristic dispatch:

OFFICE U. S. MILITARY TELEGRAPH,
WAR DEPARTMENT,
WASHINGTON, D. C., August 3, 1864.

Cypher. 6 P.M.,

LT. GENERAL GRANT,
City Point, Va.

I have seen your despatch in which you say, "I want Sheridan put in command of all the troops in the field, with instructions to put himself south of the enemy, and follow him to the death. Wherever the enemy goes, let our troops go also." This, I think, is exactly right, as to how our forces should move. But please look over the despatches you may have received from here, even since you made that order, and discover, if you can, that there is any idea in the head of any one here, of "putting our army south of the enemy," or of "following him to the death" in any direction. I repeat to you it will neither be done nor attempted unless you watch it every day, and hour, and force it.

A. LINCOLN.

I replied to this that "I would start in two hours for Washington," and soon got off, going directly to the Monocacy without stopping at Washington on my way. I found General Hunter's army encamped there, scattered over the fields along the banks of the Monocacy, with many hundreds of cars and locomotives, belonging to the Baltimore and Ohio Railroad, which he had taken the precaution to bring back and collect at that point. I asked the general where the enemy was. He replied that he did not know. He said the fact was, that he was so embarrassed with orders from Washington moving him first to the right and then to the left that he had lost all trace of the enemy.

I then told the general that I would find out where the enemy was, and at once ordered steam got up and trains made up, giving directions to push for Halltown, some four miles above Harper's Ferry, in the Shenandoah Valley. The cavalry and the wagon trains were to march, but all the troops that could be transported by the cars were to go in that way. I knew that the valley was of such importance to the enemy that, no matter how much he was scattered at that time, he would in a very short time be found in front of our troops moving south.

I then wrote out General Hunter's instructions. [See letter, August 5th, Appendix.] I told him that Sheridan was in Washington, and still another division was on its way; and suggested that he establish the headquarters of the department at any point that would suit him best, Cumberland, Baltimore, or elsewhere, and give Sheridan command of the troops in the field. The general replied to this, that he thought he had better be relieved entirely. He said that General Halleck seemed so much to distrust his fitness for the position he was in that he thought somebody else ought to be there. He did not want, in any way, to embarrass the cause; thus showing a patriotism that was none too common in the army. There were not many major-generals who would voluntarily have asked to have the command of a department taken from them on the supposition that for some particular reason, or for any reason, the service would be better performed. I told him, "very well then," and telegraphed at once for Sheridan to come to the Monocacy, and suggested that I would wait and meet him there.

Sheridan came at once by special train, but reached there after the troops were all off. I went to the station and remained there until he arrived. Myself and one or two of my staff were about all the Union people, except General Hunter and his staff, who were left at the Monocacy when Sheridan arrived. I hastily told Sheridan what had been done and what I wanted him to do, giving him, at the same time, the written instructions which had been prepared for General Hunter and directed to that officer.

Sheridan now had about 30,000 men to move with, 8,000 of them being cavalry. Early had about the same number, but the superior ability of the National commander over the Confederate commander was so great that all the latter's advantage of being on the defensive was more than counterbalanced by this circumstance. As I had predicted, Early was soon found in front of Sheridan in the valley, and Pennsylvania and Maryland were speedily freed from the invaders. The importance of the valley was so great to the Confederates that Lee reinforced Early, but not to the extent that we thought and feared he would.
