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 HMS Erebus.
