Engraving of the re-launch of HMS 'Windsor Castle', 140 Gun First rate warship, on 14th September 1852 at Pembroke Dockyard. HMS 'Windsor Castle' had first been launched in 1849, but was lengthened and had engines fitted in 1852, thus becoming the longest three-deck warship in the world. Later that year, she was re-named HMS 'Duke of Wellington' in memory of the famous general. She served as the Baltic flagship during the Crimean war, then as flagship of the Commander in Chief Portsmouth. She was sold and broken up in 1904.
