In 1759, the Diamond sailed to unspecified ports in the Americas, Jamaica, Panama, Colombia, and more unspecified destinations in what was then known as the Spanish Caribbean, embarking and disembarking human cargo as part of the slave trade. The Diamond serves as an entry point into a discussion of the movement of Africans and African-descended captives to the Pacific Ocean and Caribbean Sea-bordered regions, the ocean memory of those human cargo lost to the voyages through the Americas, and how that loss reverberates into the present.
