Major-General, Commanding Army of the Potomac.

HEADQUARTERS OF THE ARMY, WASHINGTON, January 7, 1863.

MAJOR-GENERAL BURNSIDE, Commanding, etc., Falmouth:

GENERAL:--Your communication of the 5th was delivered to me by your aide-de-camp at 12 M. to-day.

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 circ.u.mstances 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 circ.u.mstances 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 circ.u.mstances at the time may be such as to render an attempt to cross the entire army not advisable. In that case, theory suggests that, while the enemy concentrates at that point, advantages can be gained by crossing smaller forces at other points to cut off his lines, destroy his communication, and capture his rear-guards, outposts, etc. The great object is to occupy the enemy to prevent his making large detachments or distant raids, and to injure him all you can with the least injury to yourself. If this can be best accomplished by feints of a general crossing and detached real crossings, take that course; if by an actual general crossing, with feints on other points, adopt that course. There seem to me to be many reasons why a crossing at some point should be attempted. It will not do to keep your large army inactive. As you yourself admit, it devolves on you to decide upon the time, place, and character of the crossing which you may attempt. I can only advise that an attempt be made, and as early as possible.

Very respectfully, your obedient servant,

H. W. HALLECK, General-in-Chief.

GENERAL BURNSIDE:

I understand General Halleck has sent you a letter of which this is a copy. I approve this letter. I deplore the want of concurrence with you in opinion by your general officers, but I do not see the remedy. Be cautious, and do not understand that the government or country is driving you. I do not yet see how I could profit by changing the command of the Army of the Potomac; and if I did, I should not wish to do it by accepting the resignation of your commission.

GOVERNOR JOHNSON, Nashville Tenn.:

A dispatch of yesterday from Nashville says the body of Captain Todd, of the Sixth Kentucky, was brought in to-day.

Please tell me what was his Christian name, and whether he was in our service or that of the enemy. I shall also be glad to have your impression as to the effect the late operations about Murfreesborough will have on the prospects of Tennessee.

I understand there is considerable trouble with the slaves in Missouri.

Please do your best to keep peace on the question for two or three weeks, by which time we hope to do something here toward settling the question in Missouri.

EXECUTIVE MANSION, WASHINGTON, January 10, 1863

GOVERNOR JOHNSON, Nashville, Tenn.:

Yours received. I presume the remains of Captain Todd are in the hands of his family and friends, and I wish to give no order on the subject; but I do wish your opinion of the effects of the late battles about Murfreesborough upon the prospects of Tennessee.

TO THE HOUSE OF REPRESENTATIVES: The Secretary of State has submitted to me a resolution of the House of Representatives of the 5th instant, which has been delivered to him, and which is in the following words:

"Resolved, That the Secretary of State be requested to communicate to this House, if not, in his judgment, incompatible with the public interest, why our Minister in New Granada has not presented his credentials to the actual government of that country; also the reasons for which Senor Murillo is not recognized by the United States as the diplomatic representative of the Mosquera government of that country; also, what negotiations have been had, if any, with General Herran as the representative of Ospina's government in New Granada since it went into existence."
