Monday, in position first on Gen. McClernand's right, then on his centre, and then on the left, they everywhere fulfilled their duty. I specially recommend this officer for promotion. Capt. Mann of this battery was unable to be in action. I recommend that the officers of the Thirteenth Ohio battery be mustered out of service, and that the men and material remaining may be applied to filling up the ranks of some battery which has done honor to the service. My personal thanks are due to my personal staff. Capt. S. D. Atkins, A. A. A. General, who rose from a sick-bed and was with me until I ordered him to the rear. He was absent about three hours and returned and remained throughout the battle. Lieut. J. C. Long, Ninth Regular infantry, my Aid, was peculiarly active, energetic, and daring in conveying my orders under a heavy fire. He was fortunate in receiving no wound, although one ball passed through his cap, and one through his sleeve. Lieut. Beaver, my acting A. Q. M., acted as Aid with great coolness and courage, and had his horse killed under him. Lieut. W. H. Dorchester joined me as a volunteer Aid on Sunday, and rendered valuable aid on Monday. Very respectfully, your obedient servant,
A. S. Hurlbut, Brigadier-Gen. Commanding Fourth Division.
