I have a copy of his brigade's after action report for Corinth. A bit too long for including here. I can pass on to you via email @ ggmartin55@att.net
I have but limited access to Ancestry.com. I found a J. C. Capshaw, in the 1860 census for Arkansas. Age 40, located at the Mt. Moriah Post Office, household members: Louisa, 37; Louisana, 14; James D, 12; Nancy, 10; May, 8; Martha, 6, Madison , 4, Virginia, 2.
In the 1850 Arkansas census, I found a J. C. Capshaw, age 38, born about 1812 in South Carolina, home in 1850, Marion, Quachita County.
I am unable to search further into the actual census enumeration sheets to ID occupation, family members, etc.

19th Regiment, Arkansas Infantry (Dockery's)
19th (Smead's-Dockery's) Infantry Regiment was assembled at Devall's Bluff, Arkansas, in April, 1861, and moved to Memphis, then Fort Pillow, Tennessee. Its companies were recruited in the counties of Union, Lafayette, Columbia, Ouachita, and Hot Spring. The unit participated in the Battles of Corinth and Hatchie Bridge, and reported 129 casualties. Later it was attached to General M. E. Green's Brigade, Department of Mississippi and East Louisiana. It fought at Port Gibson, then was part of the garrison captured at Vicksburg in July, 1863. After being exchanged, the regiment was reorganized and mounted. It was placed in Dockery's and Roane's Brigade, Trans-Mississippi Department, and saw action at Marks' Mills. After some minor skirmishing the unit disbanded. The field officers were Colonels Thomas P. Dockery and H. P. Smead, Lieutenant Colonel William H. Dismukes, and Major H. G. P. Williams.

Nineteenth Arkansas Infantry
The Nineteenth Arkansas was organized at Devall's
Bluff, in April, 1861, with the following officers: Colonel
H. P. Smead, of Columbia county; Lieut.-Col. Ben Hale,
of Hot Springs; Maj. D. L. Kilgore, of Magnolia; Quar-
termaster T. P. Dockery, Commissary H. Bussy. The
captains were: Company A, J. G. Johnson, of Lewis-
ville; B, H. G. P. Williams, of Hillsboro; C, B. R. Mat-
thews, of Eldorado; D, John Cook, of Falcon; E, P.
Dismukes, of Columbia county; F, J. I. Kendrick, of Co-
lumbia county; G, William C. Langford, of Eldorado;
H, James Henry, of Hot Springs county Under an act
of Congress the regiment was reorganized by electing
Tom Dockery, colonel; W. H. Dismukes, lieutenant-col-
onel, and H. G. P. Williams, major. From Memphis it
was ordered to Fort Pillow. April 12, 1862, the Federal
fleet which had caused the evacuation of Island No. ro
proceeded eighty miles below to Fort Pillow, and began
a vigorous bombardment of that place and of Randolph,
about twelve miles below, on the bluffs of Tennessee.
Both places were rendered untenable, and the Confeder-
ates were withdrawn and sent to Corinth, Miss. They
took part in the battles of Iuka and Corinth, where the
Arkansas regiments bore themselves with greatest gal-
lantry. The Nineteenth earned for its colonel, Thomas
P. Dockery, of Lamartine, promotion as brigadier-general
in the Confederate army. Colonel Dockery seemed
designed for a soldier. Nothing excited him. His ap-
parent indifference to danger was such in fact that at
times it rendered him negligent of necessary precautions.
It was this defect, really, that prevented his further pro-
motion. Upon the promotion of Colonel Dockery, Lieu-
tenant-Colonel Dismukes became colonel of the regiment.
The Nineteenth and Eighth, consolidated under command
of Col. A. L. Hutchison, served in Cleburne's division at
Ringgold gap and the retreat through Georgia.
