During the Hundred Days he was appointed cavalry commander in Belgium, under the still resentful eye of Wellington. He fought at the Battle of Quatre Bras on 16 June 1815 and at the Battle of Waterloo two days later, when he led the spectacular charge of the British heavy cavalry against Comte d'Erlon's column which checked and in part routed the French Army.  One of the last cannon shots fired that day hit Paget in the right leg, necessitating its amputation. According to anecdote, he was close to 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!" According to his aide-de-camp, Thomas Wildman, during the amputation Paget smiled and said, "I have had a pretty long run. I have been a beau these 47 years and it would not be fair to cut the young men out any longer." While Paget had an articulated artificial limb fitted, his amputated leg meanwhile had a somewhat macabre after-life as a tourist attraction in the village of Waterloo in Belgium, to which it had been removed and where it was later interred.  Paget was created Marquess of Anglesey on 4 July 1815. A 27-metre (89 ft) high monument to his heroism (designed by Thomas Harrison) was erected at Llanfairpwllgwyngyll on Anglesey, close to Paget's country retreat at Plas Newydd, in 1816. He was also appointed a Knight of the Garter on 13 March 1818 and promoted to full general on 12 August 1819.
