Harriet Tubman--no-nonsense, funny, uncannily prescient, and strategically brilliant--was one of the most important conductors on the underground railroad and hid the enslaved men, women and children she rescued in the basement kitchens of Martha Wright, Quaker mother of seven, and Frances Seward, wife of Governor, then Senator, then Secretary of State William H. Seward. Harriet worked for the Union Army in South Carolina as a nurse and spy, and took part in a river raid in which 750 enslaved people were freed from rice plantations. Martha, a "dangerous woman" in the eyes of her neighbors and a harsh critic of Lincoln's policy on slavery, organized women's rights and abolitionist conventions with Susan B. Anthony and Elizabeth Cady Stanton. Frances gave freedom seekers money and referrals and aided in their education. The most conventional of the three friends, she hid her radicalism in public; behind the scenes, she argued strenuously with her husband about the urgency of immediate abolition. Many of the most prominent figures in the history books--Lincoln, Seward, Daniel Webster, Frederick Douglass, Charles Sumner, John Brown, Harriet Beecher Stowe, William Lloyd Garrison--are seen through the discerning eyes of the protagonists. So are the most explosive political debates: about women's roles and rights during the abolition crusade, emancipation, and the arming of Black troops; and about the true meaning of the Declaration of Independence and the Constitution.
