me I have not deemed it proper to attack until I heard from either General Crook or yourself. If I do not hear from you before dark i shall retire some little distance to go into camp. I learned from a deserter belonging to Mahone's division that a large part of the rebel army is in the immediate vicinity of Amelia Court-House. Please let me hear from you as soon as possible of your own position, that of General Devin, and that of the infantry.

I have the honor to be, very respectfully, your obedient servant,

R. S. MACKENZIE,

Brigadier-General, U. S. Volunteers, Commanding Cavalry.
