Men of Fire -- by Jack Hurst (Basic Books, 2007). I've already finished this one, and a review should be up soon.
Success Is All That Was Expected: The South Atlantic Blockading Squadron During the Civil War -- by Robert M. Browning (Potomac Books, 2005). A recent purchase. I've been meaning to read this one and its companion volume about the North Atlantic Blockading Squadron for some time.
Derelicts: An account of ships lost at sea in general commerce traffic and a brief history of blockade runners stranded along the North Carolina coast 1861 - 1865 -- by James Sprunt.
Civil War Weather in Virginia -- by Robert K. Krick (University of Alabama Press, 2007). Should be a very valuable reference work.
The Irish General: Thomas Francis Meagher by Paul R. Wylie (University of Oklahoma Press, 2007). I can't say that I've had any compelling interest in Meagher, so this one arrived out of the blue. Looks like some hefty content on his post-war career in the west. He was governor of Montana, and apparently his statue in the capital is not at all a universal source of pride there.
