My great great grandfather was 2 Lieutenant, WilliamC Clouse of Co D, Ala 6th Infantry. I know he lost an arm at the Battle of Sharpsburg and was retired. He later re-enlisted for the duration. I know little else other than the fact that he is buried in Marion County, Tennessee. He lived until 1908. Are there any known photos of Co. D and if so where should I look. Thank you, Shirley
