As I’ve said several times before, had I been in Lincoln shoes, I would have executed Lee and Davis for high treason. Lincoln was way too gracious for that, indicating in the case of the latter that he’d prefer if JD got on the nearest boat out of the country.
Plus which, he was dead before Davis was captured, and only a few days after Lee surrendered.
The decision no execute or not, was made by Andrew Johnson.
Lincoln knew the value of martyrs, and chose not to create them. So, apparently, did his successor.
So, disHonest Abe sacrificed 600,000+ people to bring them back into the country so that they could get on the nearest boat out of the country which is metaphorically what they did to begin with.
You yanks are a confused bunch............
