No. 9. reports of Brig. Gen. John M. Brannan , U. S. Army, Chief of Ar tillery.

Hdqrs. Chief of Artillery, Dept. Of the Cumberland Atlanta, Ga., September 14, 1864 .

General: I have the honor to transmit the reports of corps chiefs of artillery and battery commanders of the operations of the artillery arm of the service in your army during the campaign resulting in the capture of the city of Atlanta:

In forwarding these reports I will bear witness to the efficiency and valuable services performed by the artillery of your army during the entire campaign. Heavy losses were inflicted upon the rebels by the accuracy of our fire, the skillful and daring positions taken by our batteries, frequently on the skirmish line, within short canister range of strongly intrenched works of the enemy. That it has been most destructive, we have not only the evidence of what we ourselves witnessed, but also that of the enemy.

The chiefs of artillery of corps have shown energy, efficiency, skill, and courage equal to any officers in the service. I call your attention to the reports of corps chiefs relative to subordinates. Capt. A. Sutermeister , Eleventh Indiana Battery, being attached to your headquarters under your own supervision, you are aware of the efficient and zealous manner he and his company have performed their part in the campaign, both with the 20-pounder Parrotts and 4 1/2-inch guns. The organization of the artillery into brigades under the immediate command of the corps chiefs is, in my opinion, an improvement upon the former organization, and I recommend it be retained.

We have lost the valuable services of several officers killed in battle during the campaign, viz: Capt. Peter Simonson , Fifth Indiana Battery; Capt. S. M. McDowell , Company B, Independent Pennsylvania Artillery; Capt. William Wheeler , Thirteenth New York Battery; First Lieut. O. H. P. Ayres , Sixth Ohio Battery; Second Lieut. F. Henchen , Company I, First New York Artillery.

Our loss in guns was four 3-inch Rodmans-two belonging to the Eighteenth Indiana Battery, lost on General McCook 's raid, July 30, 1864 ; two of the Chicago Board of Trade Battery, lost on General Kilpatrick 's raid, August 20, 1864 .

I would here take the opportunity to mention the effective service of the batteries serving with the cavalry command-Tenth Wisconsin Battery, Capt. Y. V. Beebe ; Eighteenth Indiana Battery, First Lieut. W. B. Rippetoe , and the Chicago Board of Trade Battery, First Lieut. G. I. Robinson , commanding-during the entire campaign. In every instance where these batteries were engaged they did good service, and their commanding officers acted with judgment and gallantry.

Guns captured in battle: Four light 12-pounder guns by the Twentieth Army Corps at Resaca, May 15, 1864 ; six light 12-pounder guns, two 10-pounder Parrott guns by the Fourteenth Army Corps at; Jonesborough, September 1, 1864 .

Guns captured, abandoned by the enemy: Four 6-pounder iron guns at Resaca, May 16, 1864 ; 20 guns of different calibers at Atlanta, September 2, 1864 ; 10 guns of different calibers at Rome.

A consolidated report of casualties and expenditure of material and ammunition during the campaign is hereto annexed.

I am, general, very respectfully, your obedient servant,

J. M. Brannan, Brig. Gen., Chief of Artillery, Dept. of the Cumberland Maj. Gen. George H. Thomas , Commanding Army of the Cumberland.
