How many slaves died on the middle passage?

Between one and two million slaves died on the crossing, leaving many corpses in the bowel of the ship to rot among his companions.

10% of slaves would die on the ships. And up to 30% if it was a bad voyage!

.......

That statistic is wrong. 20 million embarked on the voyage and about half made it.

........

Once the slaves showed signs of diseases or were dead they would throw them over board to prevent diseases spreading. On average 1/8 of all slaves were lost and 1 1/2 million Africans are buried in the Atlantic Ocean between Africa and Americas.
