Yes...a sad end indeed:

Although there were proposals to retain her as a museum ship, the Admiralty approved Warspite's scrapping in July 1946. On 19 April 1947, Warspite departed Portsmouth for scrapping at Faslane, on the River Clyde. On the way, she encountered a severe storm and the hawser of the tug Bustler parted, whilst the other tug Melinda III slipped her tow. In storm force conditions Warspite dropped one of her huge anchors in Mount's Bay, which did not hold, and the storm drove her onto Mount Mopus Ledge near Cudden Point. Later refloating herself she went hard aground a few yards away in Prussia Cove. Her skeleton crew of seven was saved by the Penlee Lifeboat W. & S. There were several attempts to refloat her but the hull was badly damaged and Warspite was partially scrapped where she lay.
An attempt to refloat her in 1950, buoyed by 24 compressors pumping air into her tanks, and watched by a large crowd, the press and the BBC, failed. There was insufficient water to float her clear of the reef in a rising south westerly gale. The salvage boat Barnet, standing guard overnight under the Warspite’s bows was holed in the engine room, towed off and eventually drifted ashore at Long Rock, a few miles to the west. By August the battleship was finally beached off St Michael's Mount and after further salvage another attempt was made to refloat her in November. The Falmouth tug Masterman spent the night on the Hogus Rocks after failing to tow Warspite; and her sister tug Tradesman had 60 foot of wire wrapped around her propeller when trying to haul Masterman off the rocks. Aided by her compressor and two jet engines from an experimental aircraft the hulk was finally moved 130 feet closer to shore and by the summer of 1955 she disappeared from view.
