I want to know the answer to the following question:
Exactly who were the slaves upon the Spanish slaveship?
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?
