From Tardis Wiki, the free Doctor Who reference
Christopher Whyte was an Englishman.
He was born in 1615. He served as a captain for the royalist cause and was wounded at the Battle of Edgehill. When Polly was separated from the Second Doctor, Jamie and Ben in 1648 London, he and Sir John Copper convinced her to help them break King Charles I out of prison in exchange for finding her companions. He saved Polly when Sir Copper tried to kill her after she fulfilled her end of the bargain. (PROSE: The Roundheads)
