did the 24 hour news cycle of the era report the Norman Conquest?
If by 24 hour news cycle you mean the 24 hours of town crier news over the course of the year, then yes without question much of it was devoted to local affairs and the exploits of their nearby relatives.
I’m not saying he knew the details of the going ons of the Chinese Song dynasty (though didint he have ruach hakodesh?) but it is hard to imagine he didnt know of local events. Troyes, is not far from normandy Where William ruled.
