Explanation:

The war of the hundred years represented a great technological leap, in the first phase with the perfection of the English cavalry and archers, and, after proving the primacy of the latter, the development of alternative weapons, such as the crossbow and the lance, and arms of efficient siege, which made it possible to take cities faster, such as cannons and trebuchets (a kind of catapult with counterweight).
