"Your ancestor was in the same company as mine. A person has letters from an ancestor who was also in the same compnay. These letters will be published in book form by the University of Tennessee Press in 2006. I am going to check to see if your ancestor is mentioned in any of the letters."

Are the letters mentioned here the letters of Pvt. David Cook of Company K? I've seen these letters referenced before, but I can't find the actual letters themselves. Any idea where these letters are?
