Nell, is the day of his death known? if it is you can research the location and activities of the regiment that day, and to find out what happened to the casualties after the battle. Most were interred near by. A few, (very few) Confederates had family members to travel and remove the remains after the war taking the bodies back home. Job S. Neill and Z.P. McAlexander of the First Arkansas Mounted Rifles killed at Wilson's Creek are two that I have personal knowledge of.
