I want to say, the real TIL is that George Canning, a Tory statesman who eventually became Prime Minister, wrote a poem in commemoration(?) of the leg, and it is hilarious. The full thing is on the page, but here's one verse:

>A leg and foot to speak more plain

>Lie here, of one commanding;

>Who, though his wits he might retain,

>Lost half his understanding.

Might not top what Lord Uxbridge might have said himself while he was getting amputated; he treated the fact that his active military service was probably over by saying "I've had a pretty long run."
