This thesis (https://www.academia.edu/31904875/Image_and_reality_in_medieval_weaponry_and_warfare_Wales_1100_1450?email_work_card=title) may be of value to those with an interest in medieval Welsh warfare. Don't think it is particularly radical reinterpretation but covers a lot of evidence.Unfortunately, most of the images are missing (I assume for copyright reasons).
Yes, thank you it is very interesting.
