HDQRS. FIRST BATTALION ARKANSAS CAVALRY, Near Road where Shelby fought yesterday, April 16, 1864.

COLONEL: I have been near enough to see the train pass. They are moving very leisurely along, with a guard of about 6 men to the wagon, cavalry and infantry, mostly infantry. I think they are too strong for me to attack them, unless as a feint to cover some other move. I think by attacking them in two or three places at once we might destroy a large portion of their train; that is, with a sufficient force. Colonel, I will await here for orders. This road can be traveled with artillery very easily, but I think it will not be long until the rear will pass here.

Very respectfully,

RAS. STIRMAN,
Lieutenant-Colonel, Commanding Battalion.

[Indorsement.]

Respectfully forwarded, for General Marmaduke's information. I sent Colonel Stirman out after sunrise this morning. He came to the road about 8 o'clock, and saw cavalry, infantry, and their trains.

LITTLE ROCK, September 6, 1864.
Brigadier General C. C. ANDREWS:

Dispatches just received from Lewisburg by messenger. Colonel Stirman, C. S. Army, crossed at Dardanelle with 300 well-mounted men yesterday. They moved toward Dover, where Jackman is with 100. The steamers reached Lewisburg. Captain Napier beat Witt: killed 7 and captured Captain Livingston and 3 men. Rebel cavalry are probably moving to Dardanelle to cross.

Major-General.
