High Quality Content by WIKIPEDIA articles! HMS Amfitrite was a 38-gun fifth-rate frigate of the Royal Navy. She had previously served with the Spanish Navy before she was captured during the Napoleonic Wars and commissioned into the Royal Navy. The Admiralty renamed her HMS Blanche after she had spent just over a year as Amfitrite. She was the only ship in the Navy to bear this specific name, though a number of other ships used the conventional English spelling and were named HMS Amphitrite. Her most notable feat was her capture of Guerriere in 1806. Blanche was wrecked in 1807.
