How would you have treated confederate leaders?

I would have turned them and all Southern whites to the Southern blacks as slaves, in order to give them an opportunity to pay their debts and earn their freedom.

As for the question. Complete pardon and automatic citizenship back into the US. As for the planters and civilians, full and unquestioned reparations for the destruction of private property as well as the forced return of all western VA counties back to Virginia (even though this was actually done after the war and WVA decided to stay a state).

And how would you have punished the blacks?

2. Break up plantations and give land to both poor whites and blacks.
3. Permanent federal troops.
4. Anyone under the age of 12 gets sent to northern boarding schools until they come of age.

For once MasterJedi comes up with some good ideas!

I'd also institute a lifetime ban on the right to vote and own property for all Confederate veterans. I'd also send federal troops around to destroy and desecrate every Confederate graveyard, and at random select some dead veterans to be dug up, have their bodies cut to pieces and have the pile be left at their family's doorstep.

We'd still be fighting the war if those ideas above had been implemented.

I think you meant to say 'those idears'.
