Wow, that's amazing!
Nothing to really contradict here, but I can see what you mean about the areas of Resistance activity, it looks slightly messy. Maybe use little circles with their respective symbols in? A three pointed star for the National Battalions, the double-k for the Kibbo Kift, King Edward the Confessor's cross for the Edenists?
Workin' on it, think it will look pretty good.
So, for details on the inset map: how much territory do the Nazis control on the "other side?" Do they have allies there?
