I was told at university by a professor of Canadian history that the British had been trying to figure out for some weeks how they would get up the cliffs at Quebec. (They were opposite the Quebec City, where the city of Levis now is) Some officers went for a walk and noticed women washing clothes in the river opposite. They watched how the women got back up the hill, and it was this path that they used to scale the heights. It was in fact defended, but the first troops up the path were led by a Scotsman who could speak French without an accent. He tricked the sentries into believing that French troops were coming up the path, and the next morning the British were outside the walls of the city.

(When the Americans attacked Quebec some years later they had no such luck. They attacked in a blinding snowstorm and were easily chased away. They did capture Montreal, where they introduced the first printing press into Canada.)
