What was the military result of the Hundred Years War?

Answer 1

After the Hundred Years War in Europe, Kings and other national leaders started to depend on standing armies or even mercenary troops rather than depending

on their nobility (aristocracy) to provide armed troops to protect their nation or wage war.

Also, after the Hundred Years War, soldiers with either long bows, cross bows, or

eventually gun powder weapons became more effective in open field battles than medieval knights with lances or swords on horseback. In sieges, cannons became

the preferred weapon as opposed to ancient siege machines (battering rams,

covered siege towers, and such).

Answer 2

Despite many English victories in the War's early years, in the end the King of England had lost all the lands in France that he held in fief before the start of the war, keeping only a toehold by occupying the city of Calais. So the military result was in France's favor; not by any crushing defeats of the English on the battlefield, but because England simply lacked the resources to annex or keep France occupied by itself. Its early strong position - including even the occupation of Paris itself - could only be maintained through its alliances with the Duke of Burgundy and the King of Navarre. Once these decided to switch sides and side with the French king, the French could gradually retake all the lands held before by the English.
