An interesting and parallel thread here which raises the issue of historical accounts of cavalry being 'over glossed' as well as some other interestingpoints.

the link in the article is interesting.....highlighting how a 70-90lb woman can knock over a horse + jocket weighing 7-900 lbs travelling at 35 miles per hour.

If I had the option of being the armoured infantryman behind a shield or the rider cantering at him......I know my preference. :)
