Time Team Special tonight at 9pm on Channel 4. As if there werent enough horrors associated with the First World War already, tonights special episode unearths a new one, a secret and horrifying British weapon deployed on the first day of the Battle of the Somme in July 1916. Called the Livens Large Gallery Flame Projector, it fired a jet of flaming diesel oil 100 metres long over the German trenches. Not a single piece of the weapon was thought to be in existence until remnants were discovered at an archaeological dig on the frontline of the Somme. Tonight, Tony Robison joins the dig and watches as Royal Engineers produce a replica Projector and fire it up for one last, terrifying blast. Flyingmonkey, who leads our WW1 tours, was involved in this project.
