A tornado like that hitting London now would be striking a city of more than 8 million, but in 1091 estimates for London's population range from as few as 10,000 to as many as 20,000. In October of 1091, actually, there were even fewer people in London than usual. Thanks to the Anglo-Saxon Chronicle, we know that King William II was up north with his retinue and army fighting King Malcolm Canmore of Scotland (1038-1093). William prevailed, and was out of town when disaster struck. All things considered, it was probably the luckiest military campaign he ever undertook.
