WAR DEPARTMENT,

Richmond, February 8, 1862.

SIR: The condition of your department in consequence of the largely superior forces of the enemy has filled us with solicitude, and we have used every possible exertion to organize some means for your relief.

With this view the following orders have been issued to-day and the following measures adopted:

1st. We have ordered to Knoxville three Tennessee regiments---Vaughn's, Maney's, and Bate's--the First Georgia Regiment and four regiments from General Bragg's command to be forwarded by him. This will give you in East Tennessee the following force, viz: As above, eight regiments. Add Gillespie's Tennessee, one regiment; Vaughn's North Carolina, one regiment; one regiment cavalry; Stovall's battalion and another from North Carolina, together one regiment--total, twelve regiments, besides Churchwell's command at Cumberland Gap, the other forces stationed at different passes by General Zollicoffer, and a number of independent companies.

The whole force in East Tennessee will thus amount, as we think, to at least fifteen regiments, and the President desires that you assign the command to General Buckner.

2d. The formation of this new army for Eastern Tennessee will leave General Crittenden's army (augmented by Chalmers' regiment and two or three batteries of field pieces already sent to him) free to act with your center.

Colonel Chalmers will be nominated to-morrow brigadier-general. You might assign a brigade to him at once.

The President thinks it best to break up the army of General Crittenden, demoralized by its defeat, and that you should distribute the forces composing it among other troops. You can form a new command for General Crittenden, connected with your own corps, in such manner as you may deem best.

General Crittenden has demanded a court of inquiry, and it has been ordered; but from all the accounts which now reach us we have no reason to doubt his skill or conduct in his recent movements, and feel convinced that it is not to any fault of his that the disaster at Somerset is to be attributed.

3d. To aid General Beauregard at Columbus I send orders to General Lovell to forward to him at once five or six regiments of his best  troops at New Orleans.

4th. I have sent to Memphis arms for Looney's regiment; to Knoxville 800 percussion muskets; to Colonel Chalmers 800 Enfield rifles for his regiment, and to you 1,200 Enfield rifles. The Enfield rifles will be accompanied by a full supply of fixed ammunition. They form part of a small cargo recently received by us, and of the whole number (6,000) one-third is thus sent to you, besides which we send 1,600 to Van Dorn.

5th. We have called on all the States for a levy of men for the war, and think that in very few weeks we shall be able to give you heavy re-enforcements, although we may not be able to arm them with good weapons. But we have another small cargo of Enfield rifles close by, and hope to have some 10,000 or 12,000 safe in port within the next two or three weeks.

I forgot to say that the rifles already received may not reach you for eight or ten days, as they were introduced at a port quite far south.

I am, your obedient servant,

 Secretary of War.
