There’s a very good documentary series on the English Civil War called ‘The English Civil War’ from 2005 which it looks like is available on YouTube.
The episode on the trial of the regicides (called The Trial of the King Killers) who were apprehended in England is well worth watching.
My high school, in Boston, was chartered by Charles I. I’d always assumed it was in the middle of nowhere, and perhaps it was, hence being chosen as a place to hide. But there was a lot of commmunication and legal process in place as well!
