In December of 1847, EBB's "The Runaway Slave at Pilgrim's Point," a poem also calling for social justice, was published in The Liberty Bell in Boston, Massachusetts. The Liberty Bell was sold by the Boston Female Anti-Slavery Society to raise money for abolitionist causes, and EBB was invited to contribute partly because of the reputation for bold protest that she had attained through "Cry of the Children."  Just as "The Cry of the Children" influenced British society and law in regards to child labor, "The Runaway Slave at Pilgirm's Point" combatted slavery.

EBB lived at 50 Wimpole St. in London from 1838 -1846, meaning that she lived here when "The Cry of the Children" was published in 1843.
