At the Battle of Waterloo on 18 June 1815, Lord Uxbridge, commander of the Allied cavalry, was hit in the leg by one of the last cannon shots of the day. In the popular story, he was beside the Duke of Wellington and said: “By God, sir, I’ve lost my leg!” Wellington replied: “By God, sir, so you have!”
The exchange may not have happened in these words. Horace Seymour, who helped carry Uxbridge from the field, told the politician John Wilson Croker another version, which Croker wrote in his diary in 1818: “I have got it at last,” and “No? Have you, by God?”
