I can't recall how I found this post, which was on Lisa Voisin's web site, written late in 2012, but I thought it good enough to save to my iPad desktop. It's about things writers tend to forget when writing fight scenes. I keep mine vague, but some years ago I did take the trouble to try it out for myself by joining the Society For Creative Anachronism and let me tell you, even with a rattan sword and basic armour made with carpet, I soon learned what you can't do in a fight!
Anyway, here's the link to the post - and I should say that even the comments are valuable. I never knew most of the things said in those.
Follow, read, enjoy, and let me know what you think.
