Harriet Tubman became the most famous conductor of the Underground Railroad. She began helping to free slaves, making over 19 trips into the South bringing her passengers back safely, never losing a single one. Her diligent efforts earned her the nickname “Moses”. During her work, she met many leaders including Frederick Douglass, John Brown, and Sojourner Truth. After the break out of the Civil War in 1861, Harriet Tubman returned to the south to care for the thousands of slaves who had been abandoned as well as injured soldiers.
