This is a Royal Naval undress coat of the standard pattern for 1795-1812, worn by Admiral Lord Horatio Nelson when commanding the British fleet at the Battle of Trafalgar in 1805. In this major naval battle, the British defeated the combined fleets of French and Spanish navies, ending Napoleon's threat to invade Britain. However, Admiral Nelson was shot at the height of the battle and mortally wounded. Ten years later, Napoleon's defeat at Waterloo would end his threat to Britain forever.
This is one of three artificial legs made for Henry Paget, Lord Uxbridge, who commanded the British cavalry at the Battle of Waterloo. He was hit on the right knee by a canister shot, after the missile had passed over the neck of Wellington’s horse, Copenhagen.
