1. CSS Alabama vs USS Kearsarge: Cherbourg 1864 by Mark Lardas (Osprey, 2011).
Vol. 40 in Osprey's Duel series.
2. Gettysburg's Forgotten Cavalry Actions: Farnsworth's Charge, South Cavalry Field, and the Battle of Fairfield, July 3, 1863 by Eric J. Wittenberg (Savas Beatie, 2011).
This is a newly revised and updated edition. In addition to the main text discussions of the three major actions named in the book's subtitle, the appendices include OBs, walking/driving tours, and the full text of Wittenberg and Petruzzi's rebuttal of Gettysburg licensed tour guide Andie Custer's theory on where Farnsworth's charge occurred. Petruzzi has a nice post about the new edition here.
