more aristocrats were killed at Crécy and Poitiers than by the Black Death.
I don't know where that stat is taken from, but assuming it's true it's pretty amazing. It took the French army 10 years to recover after Crecy, to a point where it could take the field against the English army again. And the French army at Poitiers was probably pretty small compared to what it had been at Crecy 10 years before.
I wonder why there was such carnage at Crecy? Why did so many French nobles die, and how did the French King and Prince end up as prisoners? I have read several books about that campaign, including the fairly recent ones by Curry etc, but I still don't really understand how this massacre could have occured.
