Thanks for the PDF, Nick. I've saved a copy. Might try to improve my technique the next time I put the brush to some 28mm Confederates.
In case you didn't know...the idea of a "Legion" in the black powder era, being a small brigade-sized force combining infantry, cavalry and artillery, was presented to the Enlightenment by Maurice de Saxe in his
Reveries on the Art of War. The concept was implemented in the real world by several freikorps commanders in the Seven Years War, and found to be useful in the kleine krieg. In North America, both sides in the AWI raised Legion-style units, again for irregular service. Anthony Wayne's 1794-6 Legion of the United States, the army that won Little Turtle's War, was such a unit on the scale of a strong brigade.
It is possible that the concept of the Legion as an independent all-arms force appealed to certain authoritarian personalities in the Confederacy. It's true that the Hampton and Cobb Legions that joined the Army of Northern Virginia were broken up into their component parts. However, the Legion concept was not entirely dysfunctional in the ACW. Thomas' North Carolina Legion is one such unit that served effectively in irregular warfare in the ACW:
