Silas Claborn Turnbo died in Oklahoma 1925, and is buried in Park Grove Cemetery, at Broken Arrow, Oklahoma. He also published several vignettes of life in prewar and postwar Marion County, "Silas Turnbo's Tales of the Ozarks", that are fascinating, informative and highly entertaining. It's available in reprint.

His history of the 27th Arkansas Infantry was based in part on a journal he kept during the war, which he expanded with reminiscences of the events mentioned in his diary. It's one of the few regimental histories of an Arkansas outfit in the Trans-Mississippi Department. Definitely a keeper.
