HMS Montagu was a Duncan-class pre-dreadnought battleship constructed for the British Royal Navy, notable for being one of the fastest battleships of her time, capable of reaching 19 knots. She measured 432 feet (132 meters) in overall length, with a beam of 75 feet 6 inches (23.01 meters) and a draft of 25 feet 9 inches (7.85 meters). Her displacement ranged from approximately 13,270 to 13,745 long tons normally, with a full load displacement reaching up to 15,200 long tons. The ship’s crew comprised around 720 officers and ratings. Built to counter fast Russian battleships, Montagu was launched on 5 March 1901 and commissioned in July 1903 after her sea trials. Her main armament consisted of four 12-inch (305 mm) guns mounted in twin turrets fore and aft, complemented by a secondary battery of twelve 6-inch (152 mm) guns housed in casemates, along with smaller guns for defense against torpedo boats. She was also equipped with four 18-inch (457 mm) submerged torpedo tubes. Her armor protection included an 8-inch (203 mm) thick main belt, with the turrets protected by 8 to 10 inches of armor, and a conning tower with 12-inch-thick sides. Initially serving in the Mediterranean Fleet, Montagu transferred to the Channel Fleet in 1905. In May 1906, during wireless telegraphy experiments, she ran aground off Lundy Island after a navigation error in fog, suffering extensive damage including a 91-foot (28-meter) gash on her starboard side, hull breaches, torn propeller shafts, and damage to her bilge keels and rudder. Despite efforts involving pumps and attempts to refloat her, the vessel was deemed a total loss. The wreck was subsequently broken up for scrap over the following 15 years, with some parts, including her guns, being recovered and reused. The site of her wreck, located on the seabed, has become a popular diving location and was granted protected status by the British Government in 2019. The incident was attributed to faulty navigation and fog, leading to a court martial that reprimanded her captain and navigation officer.
