ARMY CORRESPONDENCE Camp 3d O.V.C., Rosewell, Ga. 14 Miles N.E. Marietta July 16, 1864. Dear Sir: Since writing my last, we have done but little fighting. We had some skirmishing on the 4th, in which company B, had one man killed and one wounded. This Division moved to the left on the 5th, and have held a detached position since that time-guarding the crossing of the Chattahoochee, and scouting about the country in search of Guerrillas, Rc. We found the bridge near this place burned; the rebels having fired it as they retreated. No large force of rebels have been seen or heard of on this side of the river since the 5th. Finding a large cotton factory here, that had been in operation for the benefit of the Confederacy, it was burned by order of Gen. Garrard, and its 500 operators sent to Marietta, there to be disposed of in accordance with the rules of war. As company H was guarding a forage train from Marietta to this place on the 10th inst., four of the rear guard were captured rebel scouts dressed in federal uniform, came upon them suddenly-surprised and took them away-without being able to fire a shot. They attempted to take another, but did not succeed. After taking the four they charged on the remainder of the guard, which fired upon them and drove them back. The captured men were from Fulton county, and old soldiers, having been with the company since its organization. Their names are as follows: Sergt. Thomas Statesman, John S. Lawrence, William P. Rogers, Alfred Stout. Lieut. Lewis of Col, Lang's Staff CHIEF of Topographical Engineers was captured at Atlanta the same day. The 3rd left camp day before yesterday on a scout up the river about 29 miles. Returned yesterday with two prisoners, 40 or 50 horses and a lot of tobacco. We found no camps, or indications of any force of rebels in that directions. Companies I & M, being up that way same day of the scout, killed two rebels and wounded two more. They were foraging and belonged on the other side of the river. As this is good country for forage, our horses are looking much better than when I wrote before . Weather is warm and dry. Health of the command good. Marching orders- leave tomorrow morning with six days rations, and 100 rounds cartridges. Excuse the hasty letter, and believe me yours, &c., John Spencer BRYAN WEEKLY DEMOCRAT August 4, 1864.
