Lord Uxbridge's leg was probably shattered by a piece of case shot at the Battle of Waterloo and removed by a surgeon. The amputated right limb became a tourist attraction in the village of Waterloo in Belgium, where it had been removed and interred.
Henry Paget, 2nd Earl of Uxbridge, later the 1st Marquess of Anglesey, commanded 13,000 Allied cavalry and 44 guns of the horse artillery at the Battle of Waterloo. At about 2:30 pm, at a critical stage in the battle, he led a charge of the 2,000 heavy cavalry of the Household Brigade and the Union Brigade to throw back the columns of D'Erlon's French I Corps, who were threatening to push back Picton's severely outnumbered 5th Division, with some 15,000 French infantry advancing on 3,000 British and Dutch-Belgian troops. The charge succeeded in sweeping the French infantry away in disorder, but Uxbridge was unable to rally his troops, who ran on in pursuit and were cut up by counter-attacking French cavalry. Uxbridge spent the rest of the battle leading a series of charges by British light cavalry formations, and had eight or nine horses shot from under him.
One of the last cannon shots fired on 18 June 1815 hit his right leg, necessitating its amputation above the knee. According to anecdote, which is probably apocryphal, he was close to the Duke of Wellington when his leg was hit, and exclaimed, "By God, sir, I've lost my leg!", to which Wellington replied "By God, sir, so you have!"
Perhaps a more authentic version of this exchange comes from the diary of J. W. Croker, a friend of Wellington, written on 8 December 1818, in which he recounts a conversation with Horace Seymour, the man who carried the wounded Uxbridge from the battlefield. Seymour recalled that when Uxbridge was shot he cried out, "I have got it at last," to which the Duke of Wellington responded, "No? Have you, by God?".
