IIRC, the Union Army’s band played “Dixie” as the surrendered Rebel soldiers filed past. Ulysses Grant had opened his commissary to the famished Confederates, & specified that their officers were to retain side arms (Lee did not have to surrender his sword).
There are a lot of Lincolnphobes here, but had he survived the occupation of the South would have been far milder, IMO. In fact, Lincoln would have been appalled at the ongoing PC purge of any & all reminders of the Confederacy.
Lincoln really meant his “with charity for all, with malice towards none” line from his second innaugural.
Not only would the post-war occupation been milder with Lincoln, the lack of an assasinated President would have robbed the Radicals of a martyr for which to punish the South into subservience.
