HMS Defiance, the last wooden line-of-battle ship launched for the Royal Navy, was launched on 27 March 1861. Given that wooden line-of-battle ships were effectively obsolete by the time she was fully completed, Defiance became a torpedo and mining schoolship early in her career. She was then sold to Castle's Shipbreaking Yard for breaking up in 1931. She was poignantly described as "the last of England's "Wooden Walls."
