When I was in the university we did a course called Africa history it was there I knew a lot of things that happened.
We even traveled to Badagry a place in Nigeria were this slave trade was taken seriously and visited a place were this slaves were kept in a very small room they pack hundreds of slaves inside without enough space for ventilation they defecate there and they will stay there for 3 to 4 months some of them will die there, they were being kept there waiting for the arrival of the British men.
Journey of no return when you cross as a slave there's no coming back.
I will place link's you can click so you can see video of those places.
