(1840 - 1907)
Home State: Virginia
Branch of Service: Artillery
Before Antietam
In 1860 he was a 20 year old farmer on his parent's place in Oakland, Allegany County, MD. He was appointed 2nd Lieutenant, 3rd United States Artillery on 24 October 1861 and First Lieutenant two days later.
On the Campaign
He commanded a section (2 guns) of the combined Batteries C and G, 3rd US Artillery on the Maryland Campaign of September 1862 and was afterward mentioned by Captain Gibson "as worthy of commendation and reward." From 13 to 16 September he was detached with the Sixth Pennsylvania Cavalry but they saw no action. He was with the rest of the battery near the Middle Bridge over the Antietam on 17-18 September, but was not with them at Boteler's Ford on the 19th; he'd suffered a broken nose and palate near Sharpsburg.
The rest of the War
By 30 October 1862 he was on leave for disability from his injury and disease. He was granted leave in June 1864, but failed to return by September, and was dismissed on 14 October 1864 "for absence without leave and failing to account for public money in his possession."
After the War
He was reinstated as First Lieutenant on 12 November 1867, but that was revoked 9 July 1868.
By 1870 he was well-to-do (farming?), and lived near his brother Clayton and parents at Berkley Springs, Morgan County, WV, and was "a man of leisure" there in 1880. He was a boarder with the Allen family in Berkeley Springs in 1900.
