Ben Knight

Captain Ben Knight, later Lieutenant, was an officer in the Special Forces Support Group (1 PARA) under Colonel Pemberton. (PROSE: The Ambush!) He took part in the fight against the Great Intelligence and its Robot Yeti in the London Underground. He later went with the Second Doctor to the surface to find several electronic components the Doctor required, but Knight was attacked and killed by a Yeti. (TV: The Web of Fear) His nickname was 'Little Spence', due to his relationship with Pemberton. (PROSE: The Ambush!)

In an alternative timeline he survived the Yeti incursion of the Underground, but died two weeks later at the hands of Yeti in Croydon, while protecting Victoria Waterfield. (PROSE: Legacies)
