[excerpt] ” While oysters were being shucked in the kitchen, and distinguished crowds of diners from New York’s business and political establishment feasted at Thomas Downing’s Oyster House at the corner of Wall and Broad Streets, the proprietor’s son, George, led fugitive slaves down into the basement. Amid bottles of wine and molasses, they found shelter from the bands of blackbirders, bounty hunters roaming the streets in search of runaways.”

Transatlantic Slave Trade – United Nations Organization for Education, Science and Culture (UNESCO)
“The transatlantic slave trade, often known as the triangular trade, connected the economies of three continents. It is estimated that between 25 to 30 million people, men, women and children, were deported from their homes and sold as slaves in the different slave trading systems. In the transatlantic slave trade alone the estimate of those deported is believed to be approximately 17 million. These figures exclude those who died aboard the ships and in the course of wars and raids connected to the trade.”
