I saw the insides of the big round building back about 1963. I stood in the middle and the 360 degree wall around me had various scenes from the civil war. Stonewall Jackson was propelled upwards by his horse and got shot by accident by one of his own men. A tour guide explained the various scenes. It appeared to be all white guys in the paintings. Back then (1963) most everything was all white guys in the paintings of the civil war. Just how many black guys were there during the Battle of Atlanta?! Or other Civil War battles?!
Captured black Union troops didn’t fare well in at least one particular battle, iirc.
They moved everything to a new building at the Atlanta History Center.
Stonewall Jackson is not depicted there as he was killed during the Battle of Chancellorsville over one year prior to the Battle of Atlanta.
