I am solely interested in the route and conduct of the Scottish army - I’m assuming standard rape and pillage but where would I find information about what happened in Derbyshire?
There's always room for more to be said, but there was an excellent AMA earlier this year by /u/FunkyPlaid about the Jacobite Rising of 1745:
I asked a similar question to yours (it's towards the bottom if you sort by best) and got a great answer, but there's plenty of other good stuff in there about the movement in general.
