I have read the book "Carrying the Flag" by Gordon Rhea. In the book he tells a story of an ancestor of mine "Joe Brunson" at the Wilderness. I was fortunate enough to hear Gordon Rhea speak about Charles Whilden on May 8th at the Chancellorsville Visitor Center and at the McGowan's Brigade Monument dedication on May 9th at the Bloody Angle. Another great book is "A colonel at Gettysburg and Spotsylvania" by Varina D. Brown. It's about Col. Joseph Newton Brown and his accounts of what happened at the Bloody Angle and Gettysburg. It is out of print ,but you can still find it if you search on the internet.
