Just read a quite interesting book on (among other things) Cross Keys. "Battlefield- Farming a Civil War Battlefield" by Peter Svenson. Overall theme of the book is the author bought a big slice of the battlefield, learned to farm it, and gradually learned about the site and the battle. Quite an unorthodox written treatment for a CW topic, but the analysis of the battle is pretty thorough. Good reading book too!
I hope this is of interest.
