Harriet Tubman helps brother Moses and two others escape slavery

The following spring, she headed back into Maryland to help guide away other family members.

On this, her second trip, she brought back her brother Moses, and two other unidentified men.[54] It is likely that Tubman was by this time working with abolitionist Thomas Garrett, a Quaker working in Wilmington, Delaware.[55] Word of her exploits had encouraged her family, and biographers agree that she became more confident with each trip to Maryland.[54][56] As she led more and more individuals out of slavery, she became popularly known as "Moses" – an allusion to the prophet in the Book of Exodus who led the Hebrews to freedom.[57]
During an interview with author Wilbur Siebert in 1897, Tubman revealed some of the names of helpers and places she used along the Underground Railroad. She stayed with Sam Green, a free black minister living in East New Market, Maryland; she also hid near her parents' home at Poplar Neck in Caroline County, MD. From there, she would travel northeast to Sandtown and Willow Grove, Delaware, and onto the Camden area where free black agents William and Nat Brinkley, and Abraham Gibbs guided her north past Dover, Smyrna, and Blackbird, where other agents would take her across the Chesapeake and Delaware Canal to New Castle and Wilmington. In Wilmington, Quaker Thomas Garrett would secure transportation to William Still's office or the homes of other Underground Railroad operators in the greater Philadelphia area. Still, a famous black agent, is credited with aiding hundreds of freedom seekers escape to safer places farther north in New York, New England, and Canada.

Tubman's niece Kessiah Jolley Bowley, the daughter of Linah, would be the first relative Tubman would help escape from slavery. Then, she assisted her brother Moses, followed by her three remaining brothers, Ben, Henry and Robert.
