Talk about it here.
Corporal Nicholas Blake (PROSE: Legacies) was an officer in the British Army. He took part in the fight against the Great Intelligence and its robot Yeti in the London Underground.
While attempting to recover the Second Doctor's TARDIS, Blake, Colonel Alistair Gordon Lethbridge-Stewart and several soldiers were pinned down in a Covent Garden yard by the Yeti, where all the soldiers expect Blake and the Colonel were killed. He and the Colonel took refuge in a warehouse, where they hid on top of some boxes. However, Blake was dragged away and killed by one of the Yeti. (TV: The Web of Fear)
In an alternative timeline, Blake survived the incursion in London, and was serving under Colonel Pemberton when he was killed in Croydon. (PROSE: Legacies)
