Not strictly military, but certainly an interesting insight into the weaponry available to citizens to do mayhem. The murder maps (https://medievalmurdermap.co.uk/) now include cases from York and Oxford. With a daughter living in York, I know a bit about the city centre, so interesting to see some of the criminal activities that have taken place in the past.
Oh yes, very jolly. I especially like the apparent mayhem caused by and to various scholars in Oxford. Clearly, the problem of highly strung students going off the rails is not a new one.
