William Still, born in Burlington, New Jersey, in 1821 to parents who had escaped slavery on Maryland’s Eastern Shore, was shaped by the later reunion with a brother who had been sold south to Alabama and had bought his freedom before coming to Philadelphia in search of his family; that encounter led Still to keep detailed records of fugitives passing through his office in hopes of helping other separated African Americans reunite with their kin. Still later headed the Vigilance Committee of the Pennsylvania Anti-Slavery Society, assisted freedom seekers from the South, kept a detailed journal during the 1850s, and in 1872 published The Underground Railroad, a narrative account centered on the fugitives themselves. His work preserves the story of at least 42 enslaved people who fled the Cambridge area in October 1857 in a large escape that a Baltimore newspaper called a “Stampede”; they were well armed, and the “memorable twenty-eight,” joined by fourteen more from the same area, are documented through letters, reward notices, and newspaper articles. The account also connects to Samuel Green, a free black farmer and Methodist minister who lived near East New Market, whose son fled to Canada in 1854 under Harriet Tubman’s guidance and who was sentenced in 1857 to ten years in prison for possessing Uncle Tom’s Cabin before being pardoned in 1862, and to Thomas Garrett of Wilmington, Delaware, whose Underground Railroad station aided more than 2,000 enslaved people on their way to freedom.
