On this date in 1849, Harriet Tubman began her work with the Underground Railroad, a network of antislavery activists who helped African slaves escape from the South.
On her first trip, Tubman brought her sister and her sister's two children out of slavery in Maryland. A year later, she rescued her brother and, in 1857, returned to Maryland to guide her aged parents to freedom.
Over a period of ten years, Tubman made an estimated 19 expeditions into the South and personally escorted over 300 slaves to the North. 1863, while working with the Union Army, she conducted the Combahee River Raid, emancipating several hundred more.
