1941 May 24th.Bismark sinks HMS Hood.

• 1941 – World War II: In the Battle of the Atlantic, the German Battleship Bismarck sinks then-pride of the Royal Navy,HMS Hood, killing all but three crewmen.
• Bismarck was the first of two Bismarck-class battleships built for the German Kriegsmarine. Named after Chancellor Otto von Bismarck, the primary force behind the unification of Germany in 1871, the ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1936 and launched two and a half years later in February 1939. Work was completed in August 1940, when she was commissioned into the German fleet. Bismarck and her sister ship Tirpitz were the largest battleships ever built by Germany, and two of the largest built by any European power.
  In the course of the warship's eight-month career under its sole commanding officer, Capt. Ernst Lindemann, Bismarck conducted only one offensive operation, in May 1941, codenamed Rheinübung. The ship, along with the heavy cruiser Prinz Eugen, was to break into the Atlantic Ocean and raid Allied shipping from North America to Great Britain. The two ships were detected several times off Scandinavia, and British naval units were deployed to block their route. At the Battle of the Denmark Strait, Bismarck engaged and destroyed the battlecruiser HMS Hood, the pride of the Royal Navy, and forced the battleship HMS Prince of Wales to retreat; Bismarck was hit three times and suffered an oil leak from a ruptured tank.
  The destruction of Hood spurred a relentless pursuit by the Royal Navy involving dozens of warships. Two days later, while heading for the relative safety of occupied France, Bismarck was attacked by obsolescentFairey Swordfish biplane torpedo bombers from the aircraft carrierHMS Ark Royal; one scored a hit that rendered the battleship's steering gear inoperable. In her final battle the following morning, Bismarck was neutralised by a sustained bombardment from a British fleet, was scuttledby her crew, and sank with heavy loss of life. Most experts agree that the battle damage would have caused her to sink eventually. The wreck was located in June 1989 by Robert Ballard, and has since been further surveyed by several other expeditions.
  HMS Hood (pennant number 51) was the last battlecruiser built for theRoyal Navy. Commissioned in 1920, she was named after the 18th-century Admiral Samuel Hood. One of four Admiral-class battlecruisers ordered in mid-1916, Hood had serious design limitations, though her design was drastically revised after the Battle of Jutland and improved while she was under construction. For this reason she was the only ship of her class to be completed. Hood was involved in several showing the flag exercises between her commissioning in 1920 and the outbreak of war in 1939, including training exercises in the Mediterranean Sea and a circumnavigation of the globe with the Special Service Squadron in 1923 and 1924. She was attached to the Mediterranean Fleet following the outbreak of the Second Italo-Abyssinian War. When the Spanish Civil Warbroke out, Hood was officially assigned to the Mediterranean Fleet until she had to return to Britain in 1939 for an overhaul. By this time, advances in naval gunnery had reduced Hood's usefulness. She was scheduled to undergo a major rebuild in 1941 to correct these issues, but the outbreak of World War II in September 1939 forced the ship into service without the upgrades.
  When war with Germany was declared Hood was operating in the area around Iceland, and she spent the next several months hunting between Iceland and the Norwegian Sea for German commerce raiders andblockade runners. After a brief overhaul of her propulsion system, she sailed as the flagship of Force H, and participated in the destruction of the French Fleet at Mers-el-Kebir. Relieved as flagship of Force H, Hood was dispatched to Scapa Flow, and operated in the area as a convoy escort and later as a defence against a potential German invasion fleet. In May 1941, she and the battleship Prince of Wales were ordered to intercept the German battleship Bismarck and the heavy cruiser Prinz Eugen, which were en route to the Atlantic where they were to attack convoys. On 24 May 1941, early in the Battle of the Denmark Strait, Hood was struck by several German shells and exploded; the loss had a profound effect on the British people.
  The Royal Navy conducted two inquiries into the reasons for the ship's quick demise. The first, held very quickly after the ship's loss, concluded that Hood's aft magazine had exploded after one of Bismarck's shells penetrated the ship's armour. A second inquiry was held after complaints that the first board had failed to consider alternative explanations, such as an explosion of the ship's torpedoes. It was more thorough than the first board, and concurred with the first board's conclusion. Despite the official explanation, some historians continued to believe that the torpedoes caused the ship's loss while others proposed an accidental explosion inside one of the ship's gun turrets that reached down into the magazine. Other historians have focused on the cause of the magazine explosion. The discovery of the ship's wreck in 2001 confirmed the conclusion of both boards, although the exact reason why the magazines detonated will always be a mystery, as that area of the ship was entirely destroyed in the explosion.
