I wish to add a bit to the questions on Missouri Confederate Pension applications. There is a good workable index sorted alphabetically and by county that was done, I believe, by a Texas researcher. It references the microfilmed reels at the Missouri Archives for pensions and Confederate Home Applications. This finding aid is invaluable for an easy searh of the film.
Believe the Missouri Pensions began in 1913 and include all applicants whether denied or approved. The biggest obstacle to drawing a pension (short of having to be indigent) was proving service. Many veterans had no discharge or documentation fifty-five years following the War and had to rely on comrade accounts for proof. When I was researching Clardy's Battalion, I found a few instances where Clardy, himself, gave testimonials to a man's service. A truly treasure trove of data lies in these reels of film. I am not in my library at this writing but can do a name search for anybody wishing this information.
