I'm working on researching the 10th SC as a regiment. I'd ditto the other sources mentioned. There is also a work on C.I. Walker that will be published in the near future, an edit of his post war memoirs. I think the author has the contact with Univ. of Tennessee.
Also I understand from a source who worked with the said author that the NPS at "Stones River" does have a copy of a diary of someone in the 10th though I have never gotten up there to investigate it.
