Born into slavery in Dorchester County, Maryland, around 1822, young Araminta Ross faced adversity from an early age. These hardships transformed “Minty” into Harriet Tubman, the most famous conductor of the Underground Railroad, and her childhood knowledge of the geography of the Eastern Shore played a key role in her success in ferrying more than 70 people to freedom by 1860. Historian Anthony Cohen reveals the saga of Tubman’s life by exploring significant sites in the region where she was raised—and that shaped her dreams of freedom and equality.
