I thought most of them, with the possible exception of General Lee, had their citizenship and rights restored.
Didn't some of the Confederates go on to serve President Grant, and be elected to Congress, serve as governors, and be appointed to federal judgeships, and to serve as Generals in the U.S. army?
Yes, as an example General Longstreet served in appointed position From General Grants Presidency to Teddy Roosevelt’s Presidency. Some of the posts held, Deputy Collector of Revenue, U.S. Commissioner of Railroads, and Ambassador to the Ottoman Empire. General Gordon served as Governor of the State of Georgia and as a Senator from the state of Georgia.
