Jim, I am writing a biography of Dan Showalter who was Lt. Col. of the 4th Rgt., Ariz. Birgade of which Baird was Col. Note that your were writing a bio of Spruce Baird was very interesting to me. Will your book soon be available? I'd like to compare and share information with you. It is 2 years since your post so I just hope we can connect. You can contact me at gca7@cox.net. I hope to hear from you.
