known to me. In order to relieve you from all embarassment in my case, I enclose with this my resignation of my commission of Major General of Volunteers which you can have accepted, if my movement is not in accordance with the views of yourself, and your military advisers. I have taken the liberty to write to you personally upon this subject because it was necessary as I learn from Genl Halleck for you to approve of my general plan written at Warrenton, before I could commence the movement, and I think it quite as necessary that you should know of the important movement I am about to make---particularly as it will have to be made in opposition to the views of nearly all my General Officers, & after the receipt of a dispatch from you informing me of the opinion of some of them who had visited you.
``I beg leave to say that my resignation is not sent in, in any spirit of insubordination, but as I before said simply to relieve you of any embarrassment in changing commanders where lack of confidence may have rendered it necessary.
``The bearer of this will bring me any answer, or I should be glad to hear from you by telegraph in cipher.'' (DLC-RTL).
As printed in the Official Records (I, XXI, 944-45) Burnside's letter has an additional paragraph, third from the last, which is reproduced from ``Burnside's copy of this letter, but is not in that received by the President,'' as follows:
``In conversation with you on New Year's morning, I was led to express some opinions which I afterward felt it my duty to place on paper, and to express them verbally to the gentlemen of whom we were speaking, which I did in your presence after handing you the letter. You were not disposed then, as I saw, to retain this letter, and I took it back, but I now return it to you for record, if you wish it.''
The copy of Halleck's letter to Burnside of January 7, which bears Lincoln's original endorsement, reads as follows:
``In all my communications and interviews with you since you took command of the Army of the Potomac, I have advised a forward movement across the Rappahannock. At our interview at Warrenton, I urged that you should cross by the fords above Fredericksburg rather than to fall down to that place, and, when I left you at Warrenton, it was understood that at least a considerable part of your army would cross by the fords, and I so represented to the President. It was this modification of the plan proposed by you, that I telegraphed you had received his approval. When the attempt at Fredericksburg was abandoned, I advised you to renew the attempt at some other point, either in whole or in part to turn the enemy's works, or to threaten their wings or communications; in other words, to keep the enemy occupied till a favorable opportunity offered to strike a decisive blow. I particularly advised you to use your cavalry and light artillery upon his communications, and attempt to cut off his supplies and engage him at an advantage.
``In all our interviews I have urged that our first object was, not Richmond, but the defeat or scattering of Lee's army, which threatened Washington and the line of the Upper Potomac. I now recur to these things simply to remind you of the general views which I have expressed, and which I still hold.
``The circumstances of the case, however, have somewhat changed since the early part of November. The chances of an extended line of operations are now, on account of the advanced season, much less than then. But the chances are still in our favor to meet and defeat the enemy on the Rappahannock, if we can effect a crossing in a position where we can meet the enemy on favorable or even equal terms. I therefore still advise a movement against him. The character of that movement, however, must depend upon circumstances which may change any day and almost any hour. If the enemy should concentrate his forces at the place you have selected for a crossing, make it a feint and try another place. Again, the circumstances at the time may be such as to render
