July 23 1862, I sent a telegram to Gen. Halleck in Washington, “Since you have left here the greatest vigilance has been kept up by our cavalry to the front, but nothing absolutely certain of the movements of the enemy has been learned. It is certain, however, that a movement has taken place from Tupelo, in what direction or for what purpose is not so certain. Deserters and escaped prisoners concur in this statement, but all concurring so nearly I doubt whether they have not been misled with the view of having information reach us. It would seem from these statements that a large force moved on the 7th of this month toward Chattanooga; that Price was at Tupelo on the 17th, and made speech to his command, promising to take them back to Missouri through Kentucky; that his ordnance and provision train had moved westward with 17 days’ rations, and he has likely followed ere this.
“I do not regard this information of special value, except as giving an idea of points to watch and see if these statements are verified.
“The changes directed by you before leaving here have all been made. Morgan’s division has relieved Thomas. Sherman and Hurlbut have reached Memphis, and the entire Charleston and Memphis road is abandoned by us west of here, except at Chewalla, and a force yet retained at Grand Junction. Should anything occur within this district of a startling or important nature I will inform you by telegraph.”
