what was the military impact of the hundred years' war?
• battles were never fought the same way again - battles always used to be about knights charging on horseback, but the lessons of Crecy, Poitiers and Agincourt were that arrows were the most effective weapon of all.
• later longbows and guns became the main weapon
• there was an increased use of gunpowder cannons and handguns towards the end of the hundred years' war
• these new inventions made the castles useless so no new castles were really ever built
• this was the end of the 'mediaeval times
