My great great grandfather, William Henry Cave, and his younger brother, Franklin Charles Cave, were both in Company I of the Ninth New York Volunteer Cavalry at Gettysburg. They had volunteered in November of 1862 for nine months. I believe they were recruited as replacements for casualties to the regiment which had been originally mustered into service in October 1861. According to their compiled service records both of them were assigned to detached duties until just before the battle at Gettysburg. I don't have any confirmation that William fought in the battle, though he was reported on the muster rolls for July as present, but I know his brother Franklin was mortally wounded there during the afternoon of 1 July 1863. His service record has documents stating that he was, "wounded in his right breast," and that he "died on 23 July 1863 at Gettysburg." I've read a couple of books about the aftermath at Gettysburg as well as the "HIstory of the Ninth New York Volunteer Cavalry" by Newel Cheney, which gives a brief account of the action where Franklin was wounded, but the number of possible aid stations and the confusion that reigned during the remaining days of the battle has made it impossible to determine much about what happened to him after he was wounded. I was wondering if there are any records available about who was cared for in the various field hospitals and what treatment they may have received.
