To try and give some structure to my ECW gaming I decided to use a map of the imaginary county I've invented. But to save me some time I'll use the county of Wiltshire in southern england, changing the names of some of the main places to match my imaginary ones (eg Wallingborough).
Since I can get detailed maps of the area I'll use these for terrain info. I'll have to generate a map for movements. Wiltshire in the period had a number of castles/manor houses so opportunities for sieges etc. The roylalists will hold the north of the county and parliament the south.
