Longbows won at Crecy, but only because the crossbowmen (a) were Genoese mercenaries, and (b)did not have their pavises(a kind of shield) to fire behind. So all they had to do was get in formation and suddenly a sky full of arrows showed why it sucks to be near the French in a war.
Otherwise, they were fucking deadly. I'm just wondering, is Ollie this arrogant? What, the arrow wouldn't dare strike him because the crossbow--at point-blank range--is old?
