Sorry, I live on the Far Left Coast, in Sparks, NV, adjacent to Reno.

You will find a 20 page write up of the regiment in John Berrion Lindsley's Military Annals of Tennessee, Vol. 1, p. 155-174.

If not in your local library, it is available at the Tennessee State Library and Archives, Nashville, which also holds a lot of good
CW information.

Good hunting,

George Martin
