Encased in medieval armour and resembling an armed dustbin, Terry Jones sets out on the 1000-mile walk from the Bosporus to the Holy City - a journey that took the Crusaders two years.

Terry recounts how four in five Crusaders died on the road trying to cross a mountain in torrential rain wearing 200 pounds of iron, and how they became religious fanatics and cannibals who slaughtered a defenceless population.
