Mr. Pitts, I was able to find some information from the National Parks Service web site (http://www.nps.gov/civilwar/search) as to the Regiment Details of both the 9th Mississippi Cavalry and 17th Battalion as well as the Battle Detail of the fightl at Selma. Information pertaining to both of my great grandfathers was shown under the Soldier Details. This information might be general in nature, but it is more than I have seen elsewhere.
