HISTORY OF MADISON COUNTY. - 499

FORTIETH REGIMENT OHIO VOLUNTEER INFANTRY.

The organization of this regiment was completed at Camp Chase, Ohio, December 7, 1861, and, on the 11th of the same mouth, it left camp for Eastern Kentucky, going by railroad to Paris, Ky.. and marching thence to Paintville, where it formed a junction with Col. Garfield, who was then moving up Sandy River. On the 10th of January, 1862, the regiment participated in the battle of Middle Creek, defeating Humphrey Marshall, and after that remained in camp at Paintville, suffering very much from sickness. In February, it moved to Piketon. where, in connection with a Kentucky regiment, it remained as an outpost until June 13, when the troops moved to Prestonburg. A month later, Prestonburg was abandoned. the Fortieth going; to Louisa, where it remained until September 13, when it left Louisa and moved to the month of the Sandy, and a few days after was ordered to Gallipolis, Ohio. On the 4th of October, it moved to Guyandotte, W. Va., and, November 14, was again ordered into Eastern Kentucky.

The regiment started for Nashville, Tenn., February 20, 1863, and, on its arrival was assigned to the First Brigade, First Division, Reserve Corps, then at Franklin, which point the regiment reached in March in time to take part in a forced march after Van Dorn. On the 10th of April, when the Fortieth was on picket south of Franklin, Van Dorn attacked the line with a large mounted force. but was repulsed by the regiment alone. The Fortieth moved to Triune. on the 2d of June, and, on the 23d, the reserve corps moved forward. forming the right of Rosecrans' army in its advance on Shelbyville. Wartrace and Tullahoma. The regiment was stationed at the two latter points until September 7, when the reserve corps pushed forward rapidly to assist in the movement on Chattanooga. The regiment participated in the battle of Chickamauga. losing quite heavily, and, after falling back to Chattanooga, encamped at Moccasin Point, opposite Lookout Mountain. and finally went into winter quarters at Shell Mound, Tenn., where four companies re-enlisted.

On the 24th of November, the regiment shared in the battle of Lookout Mountain. and behaved with great gallantry. It was in the second line of battle. and, upon reaching the rebel breastworks, was ordered to halt, by Gen. Whittaker, who was in command: but not hearing the order on account of the din of battle. kept right on alone, capturing two pieces of artillery at the " White House," several hundred yards in advance of the other troops. The right of the regiment advanced to near the Summertown road, but, receiving no support. were obliged to fall back. The gallant Fortieth felt much chagrined at the result. and claimed, that if properly supported, they would have captured the rebel guns and stores on the summit of the mountain. At the close of the campaign, the regiment returned to Shell Mound. On the 20th of January, 1864, the regiment moved, and, February 6, went into camp near Cleveland, Tenn. On the 22d of February, it started on a reconnaissance to Dalton, returning to camp on the 28th. On the 2d of May, the Fortieth marched on the Atlanta campaign, participating in many of the battles before that place, and being under fire almost constantly after reaching Dalton. Companies A, B. C and D were mustered out of service at Pilot Knob. Ga.. October 7, 1864. The remainder of the regiment shared the fortunes of the Fourth Corps in its pursuit of Hood, and in its retreat before him from Pulaski. In December, those who were not veterans were mustered out at Nashville. Tenn., and the veterans were consolidated with the Fifty-first Ohio Volunteer Infantry.

After the consolidation of the Fortieth with the Fifty-first, the combined regiment was transported, with the Fourth Army Corps, to New Orleans, thence to Texas, where, at the town of Victoria, it performed guard duty for some months. It was mustered out of the service December 3, 1865, brought home to Camp Chase, where it was finally paid and discharged.

COMPANY D.

This company, called the "Buffenburgh Boys." in honor of Peter Buffenburgh, was
also organized at London, and mustered into the Fortieth at Camp Chase on the 30th of September, 1861.
