Continuing on from previous posts (here and here) listing book scheduled for the first half of next year that I have my eye out for:
John Bankhead Magruder: A Military Reappraisal by Thomas Settles (LSU, June 2009). As a subject of a book length study, this one is somewhat surprising. I'll be keeping my eye on it, and I hope it takes a broader view of his Civil War service than simply his time on the Peninsula. I am far more interested in Prince John's Trans-Mississippi career.
A Wisconsin Yankee in the Confederate Bayou: The Civil War Reminiscences of a Union General by Halbert Eleazer Paine, Samuel C. Hyde, Jr. (ed.) (LSU, May 2009).
Flames Beyond Gettysburg: The Gordon Expedition, June 1863 by Scott Mingus (Ironclad Publishing, Q1-Q2 2009). -- according to the author, it's scheduled for limited publication around the end of the year, with a late winter or early spring general release. Nice cover art, too.
I've read two of the four volumes from Ironclad's Discovering Civil War America series and found them thoroughly satisfying. Both "No Such Army Since the Days of Julius Caesar" and A Little Short of Boats: The Fights at Ball's Bluff and Edward's Ferry, October 21-22, 1861 are fascinating and truly original military studies. From the same publisher, while not part of the series noted above, John C. Pemberton's manuscript Compelled to Appear in Print (ably edited by David M. Smith) is an essential part of understanding the Vicksburg Campaign.
