I am under great obligations to them and to Lieutenant S. T. Davis, Seventy-seventh Pennsylvania Volunteers, brigade inspector (who was severely hurt by a spent grape-shot on Sunday), and Captain E. P. Edsall, Thirtieth Indiana Volunteers, acting assistant adjutant-general of the brigade, for their promptness and efficiency under the most trying circumstances during this most terrible battle. I feel it a duty to report also the gallant conduct of my orderlies, they being detached form their commands and having no opportunities to be noticed in any other way . Orderly Black, Seventy-seventh Pennsylvania Volunteers, was severely wounded (if not Killed) on the evening of the 19th, while accompanying Lieutenant Davis, of my staff, in collecting men that, owing to the darkness, had become separated from their commands. Richard Sloane, Thirtieth Indiana Volunteers, was severely wounded in the hand and head on Saturday, while carrying an order, and was compelled to go to the rear; but he reported again to me for duty on the morning of the 21st. Orderlies Marr, Twenty-ninth Indiana, and McCarty, Thirty-fourth Illinois, by their coolness and courage, showed that they were worthy of holding commissions. It is but an act of justice to say that the Thirty-fourth Illinois Volunteers, Lieutenant-Colonel Van Tassell, commanding, of this brigade, were detached at the crossing of the Tennessee River, and have been detained there since; so that that regiment had no opportunity to take a part with those whom they have hitherto accompanied in every fight in which this brigade has been engaged. I regret this deeply, as I know that regiment was anxious to be with us.

I have the honor to be, very respectfully, your obedient servant,

J. B. DODGE,

Colonel, Comdg. 2nd Brigade, 2nd Division, 20th Army Corps.

Lieutenant A. S. SMITH,

Acting Assistant Adjutant-General, Second Division.

P. S. - Accompanying this please find reports of regimental commanders, and of Captain Grosskopff, commanding Twentieth Ohio Battery.
