Slave traders violently captured Africans and loaded them onto slave ships, where for months these individuals endured the “Middle Passage”—the crossing of the Atlantic from Africa to the North American colonies or West Indies. Many Africans did not survive the journey.
In 1807, the year the embargo was passed, the total exports for the United States reached $108 million. One year later, that number had declined to just over $22 million. This is a loss of $86 million.
Hope this helps.
