Known for its popular collard greens, the 31-acre Promised Land Farm in Port Wentworth, Georgia, is steeped in history. Local lore says at the end of the Civil War, the land was given to the enslaved Roderick Steele through the “40 acres and a mule” promise, made by Union General William T. Sherman through the general’s Special Field Order No. 15, although this is unconfirmed by Atlanta Black Star.
