Interesting to watch people today more consumed civil war hate than people from that era. After the war Grant, Lee, Sherman, Nathan Bedford Forrest etc... went out of their way to offer the hand of reconciliation.
There were various reunions at battlefields, including Gettysburg, where veterans from both sides met and shoot hand and had giant picnics.
Now we are treated to have some NYU millennial chick SJW. or some chubby race studies graduate, more outraged about the men of the civil war than people who lived through it.
It was more of a mixed bag. Some people didn't forgive and forget. Some Southerners who were willing to keep quiet about the North still held grudges against Southerners didn't support their cause.

Not very often. Most reunions and commemorations were of one side or the other. The big Gettysburg reunions were organized by the state and federal governments to be symbols of national unity and happened when most veterans were already quite old.
