My great grandfather enlisted in Union Army in 1862. On the official enlistment sheet under rank is listed "Commissary" and in the remarks column is says "Scout and Pilot for Captain Russell". All other men listed had some type of military rank. He enlisted in Westernport, MD. Up to this time he lived in Berkely County, VA. His name was David Franklin Seckman. If anyone can enlighten me as to "Scout and Pilot for Captain Russell", I would appreciate it very much.
