Yesterday’s mail brought One Continuous Fight: The Retreat from Gettysburg and the Pursuit of Lee’s Army of Northern Virginia, July 4-14, 1863. This 2008 offering from Eric Wittenberg, J. D. Petruzzi, and the blogless Mike Nugent has been re-released in paperback by publisher Savas Beatie. You can find a website set up for the original hardcover here.
You can also find any number of positive reviews for this book on the web. The paperback edition includes a lenghty interview with the three authors. Even if you have the hardcover, you may want to pick up a beater copy to use while following the fine driving tour. Perfect for highlighting and marking up any of the eighteen original maps.
