Gwynfor Evans

Driver Gwynfor Ivor Evans was a sapper in Royal Engineers Corp, 33 Regiment, trained in Military Engineering (Combat). His father always believed him a fool for entering military service. He took part in the fight against the Great Intelligence and its robot Yeti in the London Underground. Evans drove the ammunition truck to Holborn when 33 Regiment, and Colonel Lethbridge Stewart, were ambushed by Yeti. He was the sole survivor of the Yeti attack in Aldwych tube station, (PROSE: The Ambush!) and ran into the Underground tunnels where he got lost for a time, until finding the command centre in Goodge Street. Evans wanted to desert the Army, but the exit gate was locked. Evans always sang when scared. (TV: The Web of Fear)

He was assigned to guard the bodies of the dead, but failed to notice the resurrection of Staff Sergeant Arnold because he was too busy having a smoke outside. He was later used as a driver for the convoy that brought reinforcements to Bledoe, when the Yeti returned. (PROSE: The Forgotten Son) He was transferred to the newly-formed Fifth Operational Corps by General Hamilton, although Lethbridge-Stewart wasn't sure what to do with him, so he handed the problem to Colonel Douglas. (PROSE: The Showstoppers) He was taken to Strommach Island by Sergeant Major Ware, who could see that Evans was a problem. (PROSE: The Grandfather Infestation) Shortly after he transferred to Imber, to undergo more intensive training with Captain Younghusband. (PROSE: The Feast of Evans)

While home on leave for Christmas, he spotted an alien creature and asked Lethbridge-Stewart for help. Samson was sent to Llanfairfach to assist, and was pleased to discover the training was finally helping Evans. Evans invited Samson to his family's Christmas meal. (PROSE: The Feast of Evans)
