Scroll down to "google". Then type in the name of the regiment (example: 5th NC Infantry Regiment).
A book was published on each confederate unit containing the list of battles the unit fought in, detailed information about the battles, and also an alphabetical listing of all the men who served in that unit and even the company. Companies contained approximately 100 men. Regiments averaged 1,100.
I've already obtained the book covering the 35th NC Infantry Regiment, and I'm awaiting the book covering the 5th. Cost is $19.95 each. You can order with credit card.
