which weapon brought significant changes to warfare during the Hundred years' war?

One of the weapons that brought significant changes to warfare during the Hundred Years' War was the longbow. The English army extensively used the longbow, which was a powerful weapon with a longer range compared to other bows of the time. It was made of yew and required considerable skill to use effectively. Longbow archers were able to unleash a rain of arrows upon their opponents from a distance, causing chaos and devastation among the enemy ranks. This new military tactic revolutionized medieval warfare and gave the English a significant advantage over the French, contributing to their successes in battles such as Crécy, Poitiers, and Agincourt. The longbow's impact on warfare during this period cannot be overstated, as it marked a shift in the importance of archers and the role of projectile weapons in medieval battles.
