Hanging Captain Gordon is the account of the capture, trial, conviction, and execution of Captain Nathaniel Gordon, the only man was was executed for the crime of slave trading in US history.

I recommend reading this book for several reasons:
To learn more about slave trading and what it entailed in the past.
To learn more about the history of New York City during the time of the Civil War.
To learn more about attitudes concerning slave trading as opposed to owning slaves during the period of time covered in this book.
To learn about how the slave trade law has been updated for current times and how slave trading continues right now.
