Where I would start with Civil War research is the Cornell "Making of America" website, which has many of the official books about the war along with countless journal articles published during the 19th Century (like Harpers). Go to http://cdl.library.cornell.edu/moa/ And then do a Boolean search for Fauquier and artillery -- just to start. The first book page listed was the index to other entries in the book, which showed: Virginia Troops. Mentioned. Artillery, Light—Batteries: Fauquier, 797, 799, 869, 870 When you get tired of browsing the Cornell collection -- say, about two years from now -- try the Michigan Making of America site. http://www.hti.umich.edu/m/moagrp/
