There is a book by William Heartsill, a member of the Rangers, "Fourteen Hundred And Ninety-One Days", available at Broadfoot Publishing. A reprint of the book costs $30. I have a copy and it reads very well. The story of how Heartsill printed the original edition of the book is amazing. http://www.broadfootpublishing.com/IndividualTitles/FOURTEEN_HUNDRED_AND_NINETY_ONE_DAYS_IN_THE_CONFEDERATE_ARMY.htm
