Chancellorsville's Forgotten Front: The Battles of Second Fredericksburg and Salem Church, May 3, 1863 by Chris Mackowski and Kristopher D. White
2nd Fredericksburg and the Battle of Salem Church get overlooked in Civil War history because they were part of the more famous Chancellorsville campaign. This battle is of special interest to me because I live about a mile from Salem Church, and my backyard was a Confederate campground the night preceding the battle.
So I definitely feel like I have a much better understanding of what happened at this battle, and why it was important. It's your typical Civil War book in that the level of detail on troop placements and movements can be a little dense, and often more than the casual reader like me really wants to know. I enjoyed reading it, and I'm smarter for having done so, even if I did skim over some of the more detailed sections. I'm sure my son loved it though. It is his book.
