The longbow was a battle winning weapon because it was a force multiplier: it enabled a small number of men to create a kinetic effect far greater
than their number. Whilst Agincourt is the most famous example of the Longbow's effect (thanks to Bill "Shakey" Shakespeare), the outcomes of the
battles of Crecy and Poitiers prove that a well disciplined force of longbowmen was a devastating force on the medieval battlefield. So much so that
it influenced British military doctrine for nearly 4 centuries.
On a point of order, the longbow, culverin and arbalest hardly classify as ancient weapons, being medieval in their origin. There is also a world of
difference between "badass" weapons and decisive weapons: the former are to be considered cool, the latter can be considered to wield a strategic
effect.



Coming from first hand experience I can say with all confidence that a Medieval longbowman did Not have the weapon experience of a Knight!
