From then on the audience represented 100 Londoners marching four miles cross-country to surprise King Henry III as he slept.
A cast of six added to the immersive atmosphere, playing short scenes representing a cross-section of 750-year-old society and improvising banter as the march went on.

As the battlefield got closer the tension ratcheted up, with Michael Webber's drunken Harvey slowly sobering, and Kieron Jecchinis's guide Thomas Barliwey leading prayers before the inevitable carnage.
It was hard not to feel nervous lined up to face where the enemy slept - now a modern housing estate.
