HMS Waterloo was a 120-gun first-rate ship of the line of the Royal Navy, launched on 10 June 1833 at Chatham. Waterloo was cut down to an 89-gun 2-decker and converted to steam at Chatham 1 April 1859 – 12 December 1859. Following the loss of the modern 101-gun steam 2-decker HMS Conqueror (1855) in 1861, Waterloo was renamed Conqueror in 1862. In 1864 she served on the China station under the command of Captain William Luard, and was paid off in 1866. In 1877 she was renamed HMS Warspite and served as a training ship at Greenhithe/Woolwich. She was destroyed by fire in 1918, with 250 boys embarked at the time. Three teenage boys later claimed to have started the fire deliberately. They were charged for the alleged act and ordered to three years' detention at a reformatory.
