Frederick Douglass based his only fictional work on the gripping true story of the biggest slave rebellion in U.S. history. The Heroic Slave was inspired by a courageous uprising led by Madison Washington in 1841. Washington rallied 18 of the 135 slaves aboard a ship bound for New Orleans, the country's primary slave-trading market. The mutineers seized control, landing the ship in the British-controlled Bahamas, where their freedom was recognized.
