I was browsing some used books this weekend and noticed a revisionist title from the early 1990s laying out the history of the Confederate Regular Army and delineating its component units and their campaign histories. My eyebrows are still a little out of joint from that find.
On this subject of units-not-previously-documented, author Fred Ray writes to draw our attention to his new Shock Troops of the Confederacy: The Sharpshooter Battalions of the Army of Northern Virginia .
He has quite a collection of blurbs, from the looks of it.
