Baron Rouge
You are just convenientely forgetting the main thing : the result of that war because if the English won some battles , in the end they were booted out of France.
You're right of course, but on the way Edward III taught the French and much of the rest of Europe of a new way to fight a war. As Ian Mortimer writes in his very readable book "The Perfect King - The Life of Edward III" (pages 396 - 397).
Whether we like it or not, Edward III was to warfare what Mozart was to music. He found a new way of doing things, and it proved as good as or better than almost everything that had gone before. Until the battle of Crecy on 26 August 1346 international conflicts were not won or lost by firepower alone, they were won by feudal armies of expensively armoured knights. On that day all this changed. Groups of English peasants and yeomen’s sons came to be the breakers of the most heavily armoured noblemen. But more than that, Edward’s stroke of genius was to take the tactic of projectile warfare -which his commanders had discovered at Dupplin Moor and which he had used at Halidon Hill - and to combine it with the chevauchée: the twenty-mile-wide front destroying everything in its path as it progressed through enemy territory. Sufficient destruction forced the enemy to attack, and any enemy advancing on a well-ordered army capable of projectile warfare - whether equipped with longbows or guns - was almost certain to be torn to pieces in the crossfire. Such methods gave Edward the confidence to march across France and win his war of rivalry with Philip de Valois. It was the most effective military strategy of the middle ages, which proved just as decisive when employed by Henry V at Agincourt in 1415. When guns replaced longbows as the weapon of choice, it was not Edward’s strategy which was outdated, only the means of putting it into action.
Also in the book is a long and detailed eight-page account of Crecy, the origins of the battle, the battle itself and the aftermath which put my views of 14th Century warfare into a new and interesting context.
