In reply to mockerkin:
The story about the battle with the Normans at Rannerdale was written in 1929 by Nicholas Size, who was the landlord of the Victoria Hotel (now called the Bridge Hotel) in Buttermere.
The valley that runs up behind Rannerdale Knotts is known locally as "the Secret Valley" and was supposed to be the site of England's last stand against the Normans. Whether the story is true, no-one seems to know. The Rannerdale bluebells are unusual in that that they grow on the open fellside. Whether that is because they are indeed growing on the blood of the defeated army, or is because a woodland originally stood where the bluebells now grow, remains a mystery.
