Well, it's true that Lee was not an infanty officer and neither were his sons (arg, their names are on tbe tip o' my tongue!), he was STILL the commander of The Army of Northern Virginia. Any one who was part of the A of NV, be they cavalry, artillery, infantry, or engineers, were still under his command. I don't think we should get so picky as "I marched with Lee", "I rode with Lee", "I fired cannons with Lee", or "I built earthworks with Lee." Man, this reminds me of a game my sister invented, called "Picking Apart Plebian Phrases."
