strong patrols constantly moving from the terminal stations, and concentrating the mass of the troops on or rear the Mississippi, prepared for such ulterior operations as the public interests may demand.

I would be glad to have you make, as soon as possible, a personal inspection of all the important points in your department, and report the result to me. I cannot too strongly impress upon you the absolute necessity of keeping me constantly advised of the strength, condition, and location of your troops, together with all facts that will enable me to maintain that general direction of the armies of the United States which it is my purpose to exercise. I trust to you to maintain thorough organization, discipline, and economy throughout your department. Please inform me as soon as possible of everything relating to the gunboats now in process of construction, as well as those completed.

The militia force authorized to be raised by the State of Missouri for its defense will be under your orders.

I am, general, &c.,

GEO. B. McCLELLAN,

Major-General, Commanding U. S. Army.

Major General H. W. HALLECK, U. S. A., Commanding Dep't of Missouri.

HEADQUARTERS OF THE ARMY, Washington, November 7, 1861.

GENERAL: In giving you instructions for your guidance in command of the Department of the Ohio, I do not design to fetter you. I merely wish to express plainly the general ideas which occur to me in relation to the conduct of operations there. That portion of Kentucky west of the Cumberland River is by its position so closely related to the States of Illinois and Missouri, that it has seemed best to attach it to the Department of the Missouri. Your operations, then (in Kentucky), will be confined to that portion of the State east of the Cumberland River. I trust I need not repeat to you that I regard the importance of the territory committed to your care as second only to that occupied by the army under my immediate command. It is absolutely necessary that we shall hold all the State of Kentucky; not only that, but that the majority of its inhabitants shall be warmly in favor of our cause, it being that which best subserves their interests. It is possible that the conduct of our political affairs in Kentucky is more important than that of our military operations. I certainly cannot overestimate the importance of the former. You will please constantly bear in mind the precise issue for which we are fighting. That issue is the preservation of the Union and the restoration of the full authority of the General Government over all portions of our territory. We shall most readily suppress this rebellion and restore the authority of the Government by religiously respecting the constitutional rights of all. I know that I express the feelings and opinions of the President when I say that we are fighting only to preserve the integrity of the Union and the constitutional authority of the General Government.

The inhabitants of Kentucky may rely upon it that their domestic institutions will in no manner be interfered with, and that they will receive at our hands every constitutional protection. I have only to repeat that you will in all respects carefully regard the local institutions of the region in which you command, allowing nothing but the dictates of military necessity to cause you to depart from the spirit of these instructions.

So much in regard to political considerations.

The military problem would be a simple one could it be entirely separated from political influences. Such is not the case. Were the population among which you are to operate wholly or generally hostile, it is probable that Nashville should be your first and principal objective point. It so happens that a large majority of the inhabitants of Eastern Tennessee are in favor of the Union. It therefore seems proper that you should remain on the defensive on the line from Louisville to Nashville, while you throw the mass of your forces by rapid marches, by Cumberland Gap or Walker's Gap, on Knoxville, in order to occupy the railroad at that point, and thus enable the loyal citizens of Eastern Tennessee to rise, while you at the same time cut of the railway communication between Eastern Virginia and the Mississippi. It will be prudent to fortify the pass before leaving it in your rear.

Brigadier General D. C. BUELL.

HEADQUARTERS OF THE ARMY, Washington, November 12, 1861.

GENERAL: Upon assuming command of the department I will be glad to have you make as soon as possible a careful report of the condition and situation of your troops and of the military and political condition of your command. The main point to which I desire to call your attention is the necessity of entering Eastern Tennessee as soon as it can be done with reasonable chances of success, and I hope that you will, with the least possible delay, organize a column for that purpose, sufficiently guard-
