HMS Terror was a Vesuvius-class bomb vessel constructed for the Royal Navy in 1813 at the Davy shipyard in Topsham, Devon. She measured approximately 31 meters (102 feet) in length on her deck and displaced about 325 tons burthen. The vessel was heavily armed with two large mortars and ten cannon, reflecting her original role as a specialized bomb ship designed to bombard fortifications with heavy ordnance. Launched in June 1813, Terror’s robust construction included a strong framework to withstand the recoil of her mortars. Initially, HMS Terror served during the War of 1812, participating in key battles against the United States, including the blockade of Atlantic ports and amphibious raids from Bermuda. Notably, she took part in the bombardment of Stonington and the Battle of Baltimore in 1814, during which she contributed to the attack on Fort McHenry—an event inspiring the U.S. national anthem. After the war, she was laid up but was recommissioned in 1828 for Mediterranean service, though she was later repaired due to damage near Lisbon. In the mid-1830s, Terror was refitted as a polar exploration vessel, leveraging her formidable strength. Her conversion included reinforcing her hull with iron plating and cross-planking to resist ice pressure, and installing steam engines—former railway locomotives rated at 25 horsepower—making her one of the first Royal Navy ships with steam propulsion. Under Commander George Back, she led an Arctic expedition in 1836-1837, which became trapped in ice near Southampton Island, suffering extensive damage and nearly sinking; she was ultimately beached in Ireland for repairs. Terror’s most notable service was during the Ross Antarctic expedition (1839–1843), under James Clark Ross, during which she traversed Antarctic waters multiple times. Prior to her final voyage, she was heavily modified for the ill-fated Franklin expedition of 1845, which aimed to navigate the Northwest Passage. Equipped with steam engines and reinforced hulls, Terror and Erebus set sail but became icebound in the Arctic, leading to their abandonment and the eventual loss of all crew. In 2016, her wreck was discovered in Terror Bay, Nunavut, remarkably preserved and lying close to HMS Erebus. The wreck’s discovery provided crucial insights into the Franklin expedition’s final days and was designated a Canadian National Historic Site. The vessel’s remains are now in Canadian custody, symbolizing a significant chapter in maritime exploration history.
