Joe Wheeler, former Confederate Major General, was elected a U.S. congessman in 1880. In 1894 he gave this speech on the cause of the Civil War to congress.
I have been trying to read how he became a Congressman in the first place, referring to Chief Justice Chase's decision forbidding of such, and there seems to be a controversy of him being promoted to Lt. General of the AoT.
