HMS Windsor 
            Castle was a triple-decker, 116 gun first-rate Royal Navy ship of 
            the line. She was renamed HMS Cambridge in 1866 or 1869, when she 
            replaced a ship of the same name as gunnery ship off Plymouth. Laid 
            down at Pembroke Dockyard as HMS Victoria, she was converted from 
            sail to steam screw whilst on the stocks, renamed Windsor Castle on 
            6 January 1855 and launched 26 August 1858. 204 feet long, and of 
            4971 tons displacement, she had a crew of 930, but almost immediately 
            entered the first-class steam reserve - The Times reported on 13 September 
            1860 reported her as among the "ships and gunboats in the first-class 
            steam reserve which could be got ready for the pennant at a short 
            notice". She was renamed HMS Cambridge in 1866 or 1869, when 
            she replaced a ship of the same name as gunnery ship off Plymouth. 
            She was later joined by HMS Calcutta as her tender, with a wooden 
            bridge between the bow of HMS Cambridge and the stern of the Calcutta. 
            Other of her tenders included HMS Gorgon, Plucky and Sabrina (around 
            1877) and HMS Bonetta, Bulldog, Cuckoo, Hecate, Plucky, Sabrina and 
            Snap (around 1890). In 1890, some of her officers were listed as bound 
            for Foudroyant and Perseus. She was towed on October 30th 1907 to 
            No. 5 Basin of the Royal Dockyard to enable the gunnery school to 
            move ashore into the Naval Barracks, paid off on November 4th that 
            year and sold to Cox on 24 June 1908 for breaking up at Falmouth.

          HMS Calcutta 
            was an 84-gun second-rate ship-of-the-line of the Royal Navy, built 
            in teak to a draught by Sir Robert Seppings and launched on 14 March 
            1831 in Bombay. She was the only ship ever built to her draught. She 
            carried her complement of smooth-bore, muzzle-loading guns on two 
            gundecks. Her complement was 720 men (38 officers, 69 petty officers, 
            403 seamen, 60 boys and 150 marines). In 1855 the ship had been in 
            reserve, but was recommissioned for the war between Russia and Britain 
            and sailed for the Baltic. After two months she was sent home again, 
            as being useless for modern naval actions. She saw action in the Second 
            Opium War as the flagship of Rear Admiral Sir Michael Seymour, under 
            the command of Captain William King-Hall. In 1858 Calcutta visited 
            Nagasaki where she stayed for one week, becoming the first ship-of-the-line 
            to visit Japan. In 1865, she was converted to a gunnery ship, moored 
            at Devonport, Devon, with HMS Cambridge.[4] She was sold to breakers 
            in 1908. Her figurehead was acquired by Admiral Lord Fisher, then 
            First Sea Lord, as she had been his first seagoing ship. [Source:
