The Sharpe author Bernard Cornwell wrote a couple of novels set in &#x2F; around Agincourt and from memory there are a few extras to throw in - but I love your last sentence&#x27;s conclusion<p>1. The extra training was enormous - thik of an army of a thousand Arnold Schwarzeneggers - these guys cold deliver hundreds of foot pounds from their arms.  Robin Hood would have been built like The Rock, not Kevin Costner.<p>2. The &quot;cheap&quot; idea is misleading - in preparation ofr agincourt a huge amount of the English economny was turned over to making arrows. During Agincourt an estimated 3&#x2F;4 million arrows were fired.  When looking at economics of ranged weapons, don&#x27;t compare Bows to guns, think RPGs<p>3. Agincourt changed everything for a generation. Thanks to mud, foolishness, and yes, longbows, France lost an entire generation of aristocracy in one day. The english were being chased out of the country and suddenly ... owned everything.<p>4. finally, crossbows really are the better weapon - once you start factory-making them, your army can be raised and trained faster,  you are not tied down to a specfific class of army recruits and you dont have to feed Arnie.
