Here’s Wayne Motts, the CEO of the National Civil War Museum, giving a great presentation on the defense of Cemetery Ridge during the third day of the Battle of Gettysburg. This comes from the Mosby Heritage Area’s Conference on the Art of Command in the Civil War.
The video’s description reads, “Wayne Motts talked about the third day of Gettysburg as the turning point of the battle and the Union defense of Cemetery Ridge. He described the background of some of the men involved on both sides and the Union response to Pickett’s Charge.”
This is well worth your time.
