This BBC documentary hosted by Alistair Cooke, which aired in 1972, is well worth watching if you have the time. The content of the documentary reflects some of the new scholarship on slavery but overall the script is marred by the Lost Cause narrative and a problematic view of Lincoln and, especially, Reconstruction. Some of the places visited by Cooke include the Custis-Lee Mansion, Shiloh National Military Park, Boone Hall Plantation, South Carolina, and Natchez, Mississippi. Enjoy.
