Maybe ?? Adams, Blanche V. The Second Colorado Cavalry in the Civil War. Colorado Magazine, Vol. VIII, May 1931.

and FWIW (and I put this here for others as I found it an interesting read as I stumbled amongst the Col 2nd Cav) a nice article on the "Soldiers Letter" the newspaper of the 2nd Cav. http://www.kshs.org/publicat/history/1999winter_miller.pdf
