Little is known about him, since he only appears in written historical records during the last three years of his life, primarily because of his interactions with the famous American frontiersmen Daniel Boone and Simon Kenton.
Encouraged and supplied by British officials in Detroit, Blackfish and others launched raids against American settlers in Kentucky, hoping to drive them out of the region.
Boone escaped in June 1778 when he learned that Blackfish was launching a siege of the Kentucky settlement of Boonesborough, which commenced in September of that year.
The siege of Boonesborough was unsuccessful, and the Kentuckians, led by Colonel John Bowman, counterattacked Chillicothe the following spring.
Character actors Anthony Caruso, Walter Coy and Robert F. Simon played Blackfish in segments of NBC's Daniel Boone television series, starring Fess Parker.
