'This reminds me very much of the myth that the British Guards were given the privilege of wearing bearskins because they defeated the Imperial Guard at Waterloo. Anyone who knows anything about uniforms knows that to be inaccurate but the myth is still encountered today.'

A myth that is even encountered on the website of the National Army Museum in London and on that of the Grenadier Guards themselves! So what is the true story of the Guards' bearskins, I wonder...?
