Seems like half the people who have a bow on television could hit a squirrel between the eyes from a mile away. Is there any knowledge about how good the archers actually were compared to what is seen.
It would be helpful if you could narrow down what period and region you're interested in!
As a follow-up question - if we're talking about English longbow archers - did they rely on being accurate and thus hitting their targets with somewhat precise shots, or did they use large, coordinated volleys that would have a sizable death toll regardless of accuracy due to sheer volume?
