That's interesting. I wonder how effective chain mail armour was at protecting against arrows though. It doesn't seem to be very effective, and as bows and arrows "evolved", maybe the material used and type of armour had to as well?
I read somewhere that bodkin arrows would pierce armour more than they broader arrowhead type, and as a result plate armour changed shape slightly to better deflect incoming arrows. I don't know if it's true, though. This would have happened more or less around the time of Henry V's victory at Agincourt.
