Some other evidence of those times is the "Red sign post". There is one on the main road to Dorchester. Apparantly, after the trials at Dorchester assizes, prisoners were marched off under guard to the ships at Portsmouth and it took several days, so they slept in certain barns on the way. The red sign post pointed to the barn.
All sorts of legends grew up around it though- Grandad told us that a highwayman had been shot at the post. No matter how hard they tried, the authorities could never scrub his blood off so in the end they gave up and painted it red! I've heard similar stories from friends.
Even into the 19th century, there was a strong folk memory of Judge Jefferies and his Bloody Assizes, it caused huge resentment in the West Country.
