The Battle of Crécy was one of the first major battles of the Hundred Years' War, fought in northeastern France. Edward III of England's army, composed of english soldiers and some german mercenaries, managed to defeat the numerically superior french army led by Philip VI. The battle saw the start of the decline of the knight+crossbow combination in comparison with the more successful longbow.
But what if the french army had won the battle? I hear that Philip was advised to rest in the first day instead of attacking straight up, but he declined (by pressure of other noble commanders) and did so anyway, so that could be a PoD. There's another PoD in the constable of France, Raoul II, not being captured by the english.
-How would such a victory affect military technological/tactical development? Would the knight+crossbow combo end up being seen as better than the longbow?
-What are the immediate effects on the Hundred Years' War? Can the french recapture Calais? Is such a battle capable of ending the war outright instead of dragging it through a century or are the english kings too greedy for the french throne?
-What happens to Philip VI?
