Embark – to board a ship
Disembark – to remove or unload cargo or passengers from a ship

Between 1724 and 1739 at least 18 vessels owned by Englishman William Gerrish engaged in the slave trade. His ships departed from London, sailed to Africa, and transported their human cargo to Antigua, St. Kitts, Montserrat, South Carolina and Virginia for disembarkment. The first ship, at least as identified in the Slave Voyages Database, was called the Negroes Nest. Others were named Flying Horse, Gaboone, Guinea Hen, Hester and Jane, London Spy, Sea Nymph, Speaker, Gally and Tryall. Over 2,933 men, women and children survived the various voyages though that is only a fraction of the original number embarked.
In 1739, one of his ships, the Black Prince, docked at the York River to sell her cargo. An advertisement in the Virginia Gazette noted that the Black Prince had lately arrived from the Gold Coast of Africa with a choice parcel of slaves to be sold at York Town along the York River. The captain, John Sibson, and crew departed London in May 1738 and arrived at their destination in Africa by September. Trade and re-outfitting was completed by March 1739. In that month the Black Prince departed Africa with 137 men, women and children shackled in the hold or maybe chained on deck. The ship reached York Town in May with 112 enslaved people remaining alive. Selling immediately commenced. By October the Black Prince had returned to London.
Between 1732 and 1739, Sibson served as captain of three slave ships, the Black Prince, the Ann and Elizabeth, and the Sarah and Elizabeth. For each four trips he made with these ships he departed London, traveled to Africa and took his cargo to Jamaica, St. Kitts, the Americas, and the York River. On these four voyages he collected 888 men, women and children. 723 survived the journey to their ports of disembarkment.
Between 1698 and 1762, the York River was a point of disembarkment for at least 163 slave ships whose captains sold 31,056 men, women and children. Again, this number represents only a fraction of the people originally boarded in Africa. One can use the Slave Voyages Database to account for some number of those who died along the Middle Passage. When the ships were emptied of their human cargo, captains sought to fill their ships with tobacco. That goal was not so easily achieved as evidenced by an ad Captain Sibson of the Black Prince placed in the Virginia Gazette:
“I find it has been industriously reported for many Years, that Ships which come from Guinea here with Slaves, are never after in Condition to take in Tobacco; which is very absurd and ungenerous, and great Discouragement to bring Negroes here: But I cannot think any Man, who has any Notion of a Ship, can ever imagine any one will venture his Life and Fortune to Sea in a Vessel that is not Sea worthy. However, to clear up all Doubts of that kind, if any Gentleman has Mind to ship any Tobacco on board me, I will cause a Survey to be made of my Vessel by whom they shall desire. and her Condition shall be reported accordingly. I am the readers most obedient servant, John Sibson.” Records indicate he was successful in his endeavor and did indeed depart with a cargo of tobacco.
William Gerrish died in 1741, a respected West India merchant. There are a number of John Sibson’s to be found in various databases one of whom died in October 1739, the month and year that Sibson returned the Black Prince to London. As for the Africans dispersed throughout the West Indies and the Americas … different methods will be needed to tell their stories by the numbers or otherwise.
