The Battle of Trafalgar, 21 October 1805 is an 1822 painting by British artist J. M. W. Turner. It was commissioned by King George IV as a part of a series of works to decorate three state reception rooms in St James's Palace and link the Hanoverian dynasty with military success.[1] This work was Turner's only royal commission, and was to stand as the pendant piece to Philippe-Jacques de Loutherbourg's Lord Howe's action, or the Glorious First of June.[1] This massive history painting measures 2,615 millimetres (8 ft 6+15⁄16 in) x 3,685 millimetres (12 ft 1+1⁄16 in) and is his largest work.[1] It was given to Greenwich Hospital shortly after its original installation. The painting now hangs in the National Maritime Museum, also in Greenwich, London.
