Here’s a Civil War Trust tour of the Thompson House, aka “General Lee’s Headquarters” at Gettysburg National Military Park. Garry Adelman and Jim Lighthizer give the tour. Of course, Gen. Lee’s actual headquarters was in the field across the Chambersburg Pike from the house, but there is considerable evidence he took some meals and held some meetings in the Thompson House.
The video’s description reads, “Jim Lighthizer and Garry Adelman gave a tour of Confederate General Robert E. Lee’s Gettysburg headquarters and talked about the property’s history and restoration. The Civil War Trust, a non-profit organization, purchased the house and surrounding land in 2015.”
