Ian not question that he is very, very fast. and he can do some impressive things.
But he use Modern arrows and a modern bow,
It is too weak compared to bows used for warfare,
(In one movie he tries to disprove this… by firing modern arrows at a mailshirt made for larping… pretty irrelevant when both bow, arrows and target is not correct)
Using the Beaux tapestry as the sourc for his Idea that shooting with a halfdrawn bow was common, is very problematic.
The Tapestry was made by people who knew nothing about archery and during a time where illustrations was symbolic. and its not a realistic picture.
So yes, it show a norman with a bow. But you can’t conclude that he use a shortbow or that is is fired halfdrawn.
Actually there is no evidence of the use of wood shortbows in western Europe… an idea that is easy to find in books. Longbows was in use long before and long after 1066. (1)
Archery in the game should be based on the types of bows, arrows and the Technichs used in Bohemia at this point. (and not based on what they did elswhere)
