Jamaica was one of Captain Samuel Pike's pirates. According to Pike, Jamaica "[would have made a fine skipper, but [was] short on guile".
He was placed in charge of guarding the captured First Doctor and Jacob Kewper, but they distracted him long enough for Kewper to knock him out, and the Doctor and Kewper escaped. When Pike learned that the prisoners had escaped, he stabbed and killed Jamaica for his failure. (TV: The Smugglers)
Behind the scenes[]
According to Toby Hadoke in the DVD commentary for The Tenth Planet, Jamaica was the first black character in Doctor Who history to have a significant speaking role.
