In June 1863, Harriet Tubman ventured into the heart of slave territory in South Carolina to carry out one of the most daring and extraordinary missions of the Civil War. In her new book Combee: Harriet Tubman, the Combahee River Raid, and Black Freedom during the Civil War, Dr. Edda L. Fields-Black—a descendent of one of the raid’s participants—shows how Tubman commanded a ring of spies, scouts, and boat pilots and played a central role in military expeditions behind Confederate lines, including the raid on June 2, 1863, which liberated 756 people. It was the largest slave rebellion in US history. Last month, Dr. Fields-Black spoke at the Watkins Museum about her research and writing.
