HDQRS. FIRST BRIG., THIRD DIV., 23D ARMY CORPS,
In the Field, Ga., July 8, 1864.
SIR: In compliance with orders, I have the honor to submit report of part taken by the First Brigade, Third Division, Twenty-third Army Corps--composed of the Sixteenth Regiment Kentucky Volunteer Veteran Infantry, Col. James W. Gault; Eighth Regiment Tennessee Volunteer Infantry, Col. Felix A. Reeve; One hundred and twelfth Regiment Illinois Volunteer Infantry, Lieut. Col. Emory S. Bond; One hundred Regiment Ohio Volunteer Infantry, Col. Patrick S. Slevin, and One hundred and fourth Regiment Ohio Volunteer Infantry, Lieut. Col. Oscar W. Sterl--in operations of said corps from 16th day of May, 1864, to the 8th day of July, both days inclusive:
May 16, brigade marched in advance of the division from the position occupied by them on the flank and rear of Twentieth Corps on the 15th instant on Tilton road, and forded the Connesauga River, some ---- miles southeast of Tilton, and marched to the old Federal road and bivouacked for the night.
May 17, marched about 10 a.m. to the Coosawattee River at Field’s Mill; were detained at this point by the crossing of parts of other corps until dark, when brigade crossed over river in rear of Second Brigade, and marched some eight miles to Big Spring, where we bivouacked for the night.
May 18, moved in southeasterly direction until we caught up to part of Twentieth Corps, near ----- Mills, where we bivouacked for the night,
May 19, moved out this morning toward Cassville, formed line, threw out skirmishers in front, and advanced to within short distance of Cassville and to the left and rear of part of Twentieth Corps.
May 20, moved out this morning on Cassville Station road; when within short distance of the station discovered the cavalry of enemy in front. The command was formed in line, with skirmishers in advance; moved forward skirmishing continually, occasionally heavy, to Cartersville, where the command was camped. Captain Bratton, of Sixteenth Kentucky Volunteer Veteran Infantry, was severely wounded during the advance; some few privates were wounded during the day. I cannot refrain from speaking in the highest terms of the efficiency and bravery of Maj. John S. White, of Sixteenth Kentucky Veteran Infantry, who was in charge of and conducted the skirmish line of brigade during the day.
May 21, brigade remained in camp during the day, except the One hundred and fourth Ohio Volunteer Infantry; the latter regiment made a reconnaissance on the Allatoona road to the Etowah River in evening, losing 2 wounded and burning station-house at river.
May 22, the One hundredth Ohio Volunteer Infantry, Sixteenth Kentucky Volunteer Infantry, Eighth Tennessee Volunteer Infantry were ordered to and did proceed to the Etowah Mills, some five miles from camp, and destroyed the mills containing large quantities of corn, flour, &c., and other buildings connected therewith, skirmishing slightly with the enemy while in vicinity of river; command reached camp about 8 p.m. May 23, brigade moved out this morning and marched to Etowah Cliffs, on north bank of Etowah River, and bivouacked for the night. May 24, crossed river on pontoon bridge of Twentieth Corps and marched to Burnt Hickory Ridge and camped for the night.  May 25, moved about 2 p.m. and marched to Burnt Hickory, when command halted until about 1 a.m. May 26, marched to and across Pumpkin Vine Creek, and were placed in position on extreme left of the division and connecting on right with Second Division of corps. The brigade advanced some distance in line in an easterly direction until ------- Creek was crossed at ------- cotton-mill, near which the skirmishers of enemy were met by our skirmish line; skirmishing continued during the day and night, the brigade losing 1 killed and 2 or 3 wounded. May 27, the command occupying the same relative position to the other portion of the division and corps, was advanced some distance to the crest of ridge immediately opposite crest occupied by enemy's fortifications, which were held by apparently a very strong force. The brigade fortified this position during the night. The command remained in this position until dark on the evening of June 1. During almost the whole time a constant fire was kept by the enemy upon our lines. I regret to report that Capt. M. C. Horton, Company D, One hundred and fourth Ohio Volunteers, was killed by a musket-ball while in rear of our first line on 28th of May. Capt. William Bishop. One hundredth Ohio Volunteers, was severely wounded; since dead; and also Second Lieut. H. Sherbondy, One hundred and twelfth Illinois Volunteers, wounded on skirmish line of the 29th, and Lieutenant Taylor, of Sixteenth Kentucky Volunteers, wounded on 27th while reconnoitering enemy's position. While in this position the enemy daily made demonstrations upon our skirmish line, the command suffering in either killed or wounded <ar73_702> every day, the majority of days in both. Brigade was relieved by a portion of Brig. Gen. Jeff. C. Davis division, of Fourteenth Corps, and moved a short distance to the rear and left, and bivouacked for the night. June 2, brigade moved this morning with the division to Brownlow's Hill, near where they were formed in line on right of Second Division. Covering front with line of skirmishers, advanced a short distance, when our skirmishers became warmly engaged. Line advanced and found enemy in position on east side of ------- Creek in edge of timber. The One hundred and twelfth Illinois Volunteers, Sixteenth Kentucky Volunteers, and Eighth Tennessee Volunteers, composing first line, charged across the creek and field and drove the enemy into their works on crest of hill, occupying and holding possession of the position from which enemy were driven, constructing temporary works during the night. June 3, brigade remained in same position; One hundredth Ohio Volunteers taken from second line, and, in connection with a brigade of Second Division, occupied works evacuated by the enemy during the day. June 4, the remainder of brigade moved into works evacuated by enemy and commenced fortifying. June 5, brigade was ordered to make a reconnaissance to the front. A section of Battery D, First Ohio Light Artillery, were ordered to proceed with brigade. The command advanced about one mile and a half, crossing a very heavy line of works evacuated by the enemy but a short time previous to our arrival; brigade returned to camp, meeting no enemy whatever. June 6, 7, 8, and 9 no change in position or otherwise. June 10, brigade marched with division to the left of Twentieth Corps. The One hundred and fourth Ohio Volunteers crossed Allatoona Creek, driving the enemy's skirmishers over the ridge; held the position until balance of brigade came up, and was placed in position. June 11, 12, 13, and 14, remained in this position, having thrown up works. While in this position our skirmish line was constantly engaged with the enemy--some few men wounded. June 15, skirmish line advanced to the works of enemy in our front and found them evacuated; brigade moved up and occupied the works. The One hundred and fourth Ohio Volunteers sent forward to occupy right of Twentieth Corps. June 16, no change in position. June 17, the enemy having evacuated their works in front during the night, brigade was moved forward and over them. After advancing short distance south of enemy's works our skirmishers met those of the enemy, and drove them rapidly to their works on east of creek, near Darby's plantation. The brigade moved up to the crest of the ridge on west side of creek. While moving into position were met with a heavy artillery fire, but owing to the protection of the crest no injury was sustained. The brigade fortified the crest during the night. Adjt. J. S. Reeve, Eighth Tennessee Volunteers, was mortally wounded by a musket-ball. June 18, no change. June 19, rebel works again evacuated, and occupied by brigade. About 5 o'clock this morning Sixteenth Kentucky Volunteers, supported by One hundredth and One hundred and fourth Ohio Volunteers, made a reconnaissance on Marietta road some two and a half miles, driving enemy's skirmishers rapidly across Noyes'  Creek on that road, capturing some 19 prisoners. Brigade was then ordered to return to Sandtown road; followed road on east of Noyes' Creek to Sandtown road, and marched in rear of Second Brigade to near the crossing of said creek. Bivouacked and threw up some temporary works between road and creek. Some 2 or 3 wounded from brigade on skirmish line. June 20, brigade did not change position <ar73_703> excepting One hundredth Ohio Volunteers crossed creek as support to Second Brigade. June 21, no change in position. June 22, moved across Noyes' Creek and past works put up by Second Brigade, and was ordered in advance of division; deployed a line of skirmishers supported by One hundred and fourth Ohio Volunteers, One hundred and twelfth Illinois Volunteers, and Eighth Tennessee Volunteers, in line, and drove the enemy's skirmishers to and past Cheney's house, on Atlanta and Marietta road, and were placed in position on crest north of Cheney's house, and fortified the same. June 23, 24, and 25, no change; our skirmish line constantly engaged with those of the enemy. June 26, moved out of works on Atlanta road and drove the enemy's skirmishers into works on the east side of Olley's Creek. Leaving the One hundredth and One hundred and fourth Ohio Volunteers in position at this point, moved the Sixteenth Kentucky Volunteers, One hundred and twelfth Illinois Volunteers, Eighth Tennessee Volunteers on Powder Springs road to country or private road, passing farm owned by Mr. Cox, for the purpose of crossing Olley's Creek at this point and turning the position of enemy, but was prevented from so doing by an almost impassable swamp. Command bivouacked for the night. June 27, moved Eighth Tennessee Volunteers to the right of swamp this morning, after a heavy and well-directed artillery fire from Fifteenth Indiana Battery, Lieutenant Harvey, and a section of Twenty-third Indiana Battery, Lieutenant Wilber commanding, where they crossed. At about same time One hundredth and One hundred and fourth Ohio Volunteers crossed on Atlanta road, and One hundred and twelfth Illinois Volunteers and Sixteenth Kentucky Volunteers on farm road before referred to, and drove enemy out of their works. The brigade is indebted for their success in a great measure to the movement of the Second Brigade, in threatening and pushing the right flank of the enemy during the time and previous to crossing. After crossing, brigade moved up Atlanta road about one mile to a favorable position and commenced fortifying same. June 28, 29, and 30, no change. July 1, 2, 3, and 4, no change in position. The right of the skirmish line was engaged more or less during our stay here; 2 or 3 men wounded. July 5, moved this morning some two miles to cross-roads at Moss' house and bivouacked for the night. July 6, moved this morning in advance of division on road to Ruff's Station, passing through one strong line of enemy's evacuated works; camped on east side of railroad. July 7, marched to near Poplar Branch of Rottenwood Creek and went into camp. July 8, marched in rear of ------ brigade in easterly direction on Soap Creek road to a point about three-fourths of a mile from the Chattahoochee River, where brigade was halted until about 5 p.m., when they were moved down to the river, crossing about 8 p.m. on pontoon bridge at mouth of Soap Creek, and bivouacked upon first ridge on east side of river, in rear of Second and Fourth Brigades. A detailed list of the casualties occurring in the brigade during the time herein reported is hereto attached.(*) I am pleased to be able to state that during all of the skirmishing, marching, and fatigue duty herein detailed the officers and men at all times faithfully and promptly performed their full duty, notwithstanding the unfavorable weather the greater part of the time, without murmur or complaint. <ar73_704> My staff officers were prompt in attending to their various duties and performed all required of them efficiently and cheerfully. It is proper for me to say that I was in temporary command of the division from morning of the 26th of May to morning of the 28th of same month, Col. J. W. Gault, of the Sixteenth Kentucky Volunteers, being in command during that time. The Sixteenth Kentucky Volunteers, owing to the continued ill health of Colonel Gault, has been commanded by Maj. J. S. White since the 29th of May. The Eighth Tennessee Volunteers, in command of Captain Ragan, during latter portion of June, and to this date. I have the honor to be, very respectfully, your obedient servant,
 J. W. REILLY,
 Colonel, Commanding Brigade.
