S. Brian Willson: It is estimated that Africa lost fifty to sixty million human beings to death and slavery during the nearly four hundred years of the transatlantic slave trade. It has been calculated that only ten to fifteen million survived the kidnapping process and the subsequent long, forced march of hundreds of miles to the African coast, during which the captives were chained to one another. If that wasn't savage enough, they were forced to endure the transport of six to ten weeks on one of 54,000 separate slave voyages, five thousand miles across the ocean. Called floating coffins, each ship held anywhere from 250 to 600 Africans. The trans-Atlantic slave trade is the largest known forced intercontinental movement of human beings in history. https://wordsmith.social/protestation/quotes#quote8079
