Twentieth Georgia Cavalry Battalion. They are little acquainted with the organization of the cavalry, and can only give the following information: That General Hampton is in command of all the cavalry and his headquarters are four miles below Reams' Station. They know of General Butler as commanding a brigade, and that General Young commands Hampton's old division. They speak of all these generals being in that vicinity. There is a battalion of dismounted cavalry operating near Emmit's [Emmon's] Mill under the command of Major Farley. They report that the Danville road is in running order; that it was finished last week. One of them was at Stony Creek Station about two weeks ago. There was a regiment of infantry and two pieces of artillery there at that time. Do not know what force there is at Reams' Station:think there is a small force of infantry with several pieces of artillery. Little can be made of their information, they are so unintelligent.

Very respectfully, your obedient servant,

JNumbers C. BABCOCK.
