HMS Terror was a specialised warship and a newly developed bomb vessel constructed for the Royal Navy in 1813. She participated in several battles of the War of 1812, including the Battle of Baltimore with the bombardment of Fort McHenry. She was converted into a polar exploration ship two decades later, and participated in George Back's Arctic expedition of 1836–1837, the successful Ross expedition to the Antarctic of 1839 to 1843, and Sir John Franklin's ill-fated attempt to force the Northwest Passage in 1845, during which she was lost with all hands along with . On 12 September 2016, the Arctic Research Foundation announced that the wreck of Terror had been found in Nunavut's Terror Bay, off the southwest coast of King William Island. The wreck was discovered south of the location where the ship was reported abandoned, and some from the wreck of HMS Erebus, discovered in 2014. Early history and military service HMS Terror was a bomb ship built over two years at the Davy shipyard in Topsham in south Devon, for the Royal Navy. Her deck was long, and the ship measured 325 tons burthen. The vessel was armed with two heavy mortars and ten cannon, and was launched in June 1813. Terror saw service in the War of 1812 against the United States, during which the ships of the North America and West Indies Station of the Royal Navy blockaded the Atlantic ports of the United States and launched amphibious raids from its base in Bermuda, leading up to the 1814 Chesapeake campaign, a punitive expedition that included the Raid on Alexandria, the Battle of Bladensburg, and the Burning of Washington. Under the command of John Sheridan, she took part in the bombardment of Stonington, Connecticut, on 9–12 August 1814. She also fought in the Battle of Baltimore in September 1814 and participated in the bombardment of Fort McHenry; the latter attack inspired Francis Scott Key to write the poem that eventually became known as "The Star-Spangled Banner". In January 1815, still under Sheridan's command, Terror was involved in the Battle of Fort Peter and the attack on St. Marys, Georgia. After the war, Terror was laid up until March 1828, when she was recommissioned for service in the Mediterranean Sea. She was removed from active service when she underwent repairs for damage suffered near Lisbon, Portugal. Early polar exploration service In the mid-1830s, Terror was
