Jem Mace fought Sam Hurst for the unofficial, and illegal, bare-knuckle heavyweight boxing championship of England and a purse of £400 on an island in the River Medway in Kent. Mace won after 39 minutes of fighting when Hurst failed to "come up to scratch" in the eighth round. Mace defended his championship the following year against Tom King on January 28, 1862 and in 1870 beat Tom Kenner in Louisana to become the "last bare-knuckle champion of the world."
