Mt. Pleasant Plains Cemetery was the final resting place for some of the passengers and conductors of the largest Underground Railroad operation in history: the escape on the sailing ship Pearl. In April 1848, after months of planning, 77 enslaved residents of the Washington area boarded the ship in darkness at the Southwest waterfront, setting sail for the Chesapeake Bay and then north to freedom.

But armed enslavers seized the Pearl where the Potomac River meets the Bay. Crew members were tried and jailed. Many of the enslaved passengers were taken to New Orleans to be sold.

Amelia Edmonson and her sons, Ephraim and Richard—who had been aboard the Pearl—were buried at Mt. Pleasant Plains Cemetery, along with Luke Carter, who hid passengers in his home before the escape. Many members of the Colored Union Benevolent Association, which established the cemetery in 1870, had family and friends on
