To the Limit and Beyond
The house lights dim, the band strikes ' Hearts of Oak' and two spotlights suddenly pierce downwards on to the sailors marching, arms interlocked, faces tensely set, into the arena. It is one of the highlights of the London season: The Royal Navy's field gun competition at the Royal Tournament
-currently celebrating its centenary.
On a fast night the race is over in 2 minutes 35 seconds. It is so fast that spectators cannot hope to comprehend the brilliance of the most violent time-and-motion action in the world. Nor could they imagine the year of discipline and blood and amputations that goes into the forging of a field-gunner. Written and narrated by Ian Wooldridge producer MICHAEL BEGG
(Highlights from this year's Royal Tournament on Friday evening)
