75th anniversary of the Battle of Gettysburg, 1938. Footage of Confederate and Union veterans shaking hands over a stone wall. I don’t know if this wall contained stones used in a stone wall during the actual battle in 1863, but probably so. It starts with the old veterans shaking hands and calling “Hello Yankee” and “Hello Johnny” and things like that, then one Confederate near the camera takes up the Rebel Yell for a few seconds. Laughter is heard (source unknown, possibly a bystander), then the old old Johnny identifies it: “That’s the Rebel Yell!”
