Brigadier-General Don Carlos Buell to Major-General Henry W. Halleck, February 5, 1862

HEADQUARTERS DEPARTMENT OF THE OHIO,       

Louisville, Ky., February 5, 1862.

Maj. Gen. H. W. HALLECK,

Commanding Department of Missouri:

GENERAL: My plan of operations was sketched in the letter which I wrote you on the — ultimo. You have, I learn from your letter and dispatches, entered upon what would have concerned it on your side, and that is a very important part of it. I regret that we could not have consulted upon it earlier, because my work must at first be slow. Besides, since I wrote you those plans have been changed, or at least suspended, in consequence of the diversion of a large part of my efficient force for other objects, which the General-in-Chief urged as of primary importance, namely, our advance into East Tennessee. I have, however, in consequence of the want of transportation, and, more than all, the impassable condition of the roads, urged him to allow me to resume my original plan, and, if I am not restricted, shall enter upon its execution at once. My troops have, however, been thrown somewhat out of position, and it will take some days to get them into place. My progress, too, must be slow, for we are dependent upon the railroad for supplies, and that we must repair as we go, the enemy having very much damaged it between Green River and Bowling Green, 40 miles. That will take ten or twelve days. I must go provided with a siege train, because the enemy is strongly intrenched with heavy artillery behind a river, and the condition of the roads will, I fear, effectually bar any plan of attack which will depend on celerity of movement.

I think it is quite plain that the center of the enemy's line—that part which you are now moving against— is the decisive point of his whole front, as it is also the most vulnerable. If it is held, or even the bridges on the Cumberland and Tennessee Rivers destroyed and your force maintains itself near those points, Bowling Green will speedily fall and Columbus will soon follow. The work which you have undertaken is therefore of the very highest importance, without reference to the injurious effects of a failure. There is not in the whole field of operations a point at which every man you can raise can be employed with more effect or with the prospect of as important results.

Very respectfully, your obedient servant,

D.C. BUELL,

Brigadier-General.
