"I'm A Good Old Rebel" ("Old Unreconstructed") was also written by a parodist--an ex-Confederate officer making fun of the sympathies of poor Southerners who had served under him as enlisted men. Anyway, nobody rode with Lee--Lee was an infantry officer."....Ely

I am currently reading a history of the Ninth Texas Cavalry,and discovered that they did indeed "ride with Lee". Major General Stephen D. Lee served as Commanding Officer of Cavalry in Mississippi under Joseph E Johnston.The "good ole rebel" in the song of the same name might very well have fought with the Arkansas,Texas or Mississippi Cavalry in the west.
