Every schoolchild knows of Harriet Tubman's heroic escape and resistance to slavery.But few readers are aware that Tubman went on to be a scout, a spy, and a nurse for the Union Army, because there has never before been a serious biography for an adult audience of this important woman.This is that long overdue historical work, written by an acclaimed historian of the antebellum era and the Civil War. Illiterate but deeply religious, Tubman left her family in her early 20s to escape to Philadelphia, then a hotbed of abolitionism.There she became the first and only woman, fugitive slave, and black to work as a conductor on the Underground Railroad. So successful was she in spiriting away slaves that the state of Maryland put a $40,000 bounty on her head.Within a year of starting her work, fellow slaves and Northerners began referring to Tubman as 'Moses' because of how many people she had freed. With impeccable scholarship that draws on newly available sources and research into the daily lives of slaves, HARRIET TUBMAN is an enduring work on one of the most important figures in American history.
