What was the key weapon for the English in most battles during the Hundred Years War?

The key weapon for the English during most battles of the Hundred Years War was the longbow. This powerful weapon allowed English archers to shoot arrows with great range and accuracy, often decimating enemy forces before they could engage in hand-to-hand combat. The effectiveness of the longbow was notably demonstrated in battles such as Crécy and Agincourt, where English archers played a decisive role in achieving victory against larger French armies.
