I want to know the answer to the following question:
Who was the leader of slaves during the New Haven anti slavery movement in 1839
All the background I'm provided with is that "New Haven was home to one of the important early events in the burgeoning anti-slavery movement when, in 1839, the trial of mutineering Mende tribesmen being transported as slaves on the Spanish slaveship Amistad was held in New Haven's United States District Court.". Is that enough to answer the question?
