Henry W. Halleck to Ulysses S. Grant, January 6, 1862

Saint Louis, January 6, 1862.

Brig. Gen. U. S. GRANT, Cario, Ill. : I wish you to make a demonstration in force on Mayfield and in the direction of Murray. Forces from Paducah and Fort Holt should meet at Mayfield and threaten Camp Beauregard and Murray, letting it be

understood that Dover is the object of your attack. But do not advance far enough to expose your flank and rear to an attack from Columbus, and by all means avoid a serious engagement.

Make a great fuss about moving all your forces towards Nashville, and let it-be so reported by the newspapers.

Take proper precaution to deceive your own men as well as the enemy. Let no one, not even a member of your own staff, know the real object. I will send you some forces from this place to increase the deception. Let it be understood that 20,000 or 30,000 men are expected from Missouri, and that your force is merely the advanced guards to the main column of attack. The object is to prevent re-enforcements from being sent to Buckner. Having accomplished this, you will slowly retire to your tormer positions, but, if possible, keep up the idea of a general advance. :

Be very eareful, however, to avoid a battle; we are not ready for that; but cut off detached parties and give your men a little experience in skirmishing.

If Commodore Foote can make a gunboat demonstration at the same time it will assist in carrying out the deception.

Very respectfully, your obedient servant,

Major-General.
