27th May
In May 1941, the German battleship Bismarck set out on what was intended to be a dangerous but carefully planned raid into the Atlantic. Germany hoped that this huge, fast and heavily armed warship, accompanied by the cruiser Prinz Eugen, would break through the northern sea routes and attack the merchant convoys on which Britain depended for survival. Instead, the voyage became one of the most famous naval chases in history.
The Bismarck was a formidable ship. She carried eight 15-inch guns, had thick armour, and was fast enough to threaten Allied shipping over a wide area. Germany did not have a surface fleet large enough to challenge the Royal Navy directly, so ships like Bismarck were meant to operate as raiders. A single powerful battleship loose among Atlantic convoys could cause panic, destroy merchant vessels, and force Britain to scatter its warships across vast distances.
The operation began when Bismarck and Prinz Eugen left the Baltic and moved through Norwegian waters. British reconnaissance soon detected them, and the Royal Navy understood the danger at once. If the German ships reached the open Atlantic, they could be extremely difficult to find. British cruisers were therefore stationed along likely escape routes, especially around Iceland and the Denmark Strait between Iceland and Greenland.
On 23 May, HMS Suffolk and HMS Norfolk sighted the German force in the Denmark Strait. In poor weather and low visibility, the British cruisers used radar and careful shadowing to keep contact while avoiding Bismarck’s guns. Their reports allowed heavier British ships to move in for an interception.
The first major clash came early on 24 May. HMS Hood, the pride of the Royal Navy, and the new battleship HMS Prince of Wales approached to engage. Hood was famous throughout Britain, but she was an older battlecruiser whose protection was not equal to that of a modern battleship. Prince of Wales, though new, was still suffering from mechanical problems and had not yet fully settled into service.
The battle was brief and devastating. The British ships initially had difficulty bringing all their guns to bear, and there was confusion over which German ship was which. After several exchanges of fire, a shell from Bismarck struck Hood with catastrophic effect. The British battlecruiser exploded and sank within minutes. More than 1,400 men were lost; only three survived.
The destruction of Hood shocked Britain. A ship that had symbolised naval power for a generation had vanished almost instantly. From that moment, the hunt for Bismarck became urgent and personal. The Royal Navy was determined that she would not escape.
Yet Bismarck had not come through the encounter undamaged. HMS Prince of Wales scored important hits before withdrawing. One shell damaged fuel tanks in Bismarck’s bow, causing oil leakage and reducing her endurance. Other damage led to flooding. Admiral Günther Lütjens, commanding the German operation from aboard Bismarck, now had to abandon the idea of an extended Atlantic raid and head instead toward occupied France, where the ship could be repaired.
The chase widened across the Atlantic. Prinz Eugen was detached, leaving Bismarck to continue alone. British ships converged from different directions, while aircraft carriers prepared to launch strikes. On the evening of 24 May, Swordfish torpedo bombers from HMS Victorious attacked. These slow biplanes looked outdated beside modern warships, but they were rugged, manoeuvrable, and capable of carrying torpedoes. They scored one hit, which did little serious damage, but the attack showed that Bismarck could be reached from the air.
For a time, however, the German ship seemed to have slipped away. In the early hours of 25 May, British shadowers lost contact. Bismarck was moving toward France, and the search briefly turned in the wrong direction. Then Lütjens, believing he was still being tracked, sent a long radio message to German command. British direction-finding helped narrow the search area, and the hunt resumed.
The decisive stage came on 26 May with the involvement of Force H from Gibraltar, including the aircraft carrier HMS Ark Royal. Aircraft from Ark Royal located Bismarck, and Swordfish torpedo bombers were sent to attack. The first strike nearly ended in disaster when the aircraft mistakenly attacked HMS Sheffield, a British cruiser shadowing the enemy. Fortunately, the torpedoes failed to explode properly. The Swordfish returned, rearmed with more reliable contact detonators, and launched again into rough weather.
That second attack sealed Bismarck’s fate. In the evening gloom, the Swordfish pressed home their assault through heavy anti-aircraft fire. One torpedo hit near the stern and jammed the battleship’s rudders. This damage was not dramatic in the way Hood’s explosion had been, but it was fatal. Bismarck could still steam, fire, and resist, but she could no longer steer properly. Instead of running for France, she was trapped on an uncontrollable course.
The German crew made desperate efforts to repair the rudders. They tried to regain control by using the engines, considered ways to free the steering gear, and struggled against flooding, damage, darkness, and heavy seas. Nothing worked. The ship that had seemed so powerful was now effectively crippled by one well-placed aircraft torpedo.
During the night, British destroyers harried Bismarck with torpedo attacks. These actions did not sink her, but they kept the crew under pressure and prevented any chance of recovery. By morning, the end was close. The British battleships HMS King George V and HMS Rodney, supported by cruisers, had arrived.
The final battle began on the morning of 27 May. Bismarck opened fire, but her damaged steering made accurate gunnery difficult. The British battleships soon found the range. Shell after shell crashed into her superstructure, turrets, fire-control positions and command areas. HMS Rodney, with her heavy 16-inch guns, closed to a punishing range, while King George V added steady fire.
Before long, Bismarck was no longer able to fight effectively. Her guns fell silent, her upper works were smashed, fires burned across the ship, and many of her crew had been killed or wounded. Yet she remained afloat. Her armour and internal construction made her extremely difficult to sink by gunfire alone.
To finish the action, HMS Dorsetshire moved in and fired torpedoes at the battered battleship. Around the same time, the German crew began scuttling measures, opening valves and setting charges to ensure the ship would not be captured. This has led to a long debate over whether Bismarck was sunk by the British or scuttled by her own men.
The most balanced answer is that both were involved. British air attack had crippled her, British gunfire had destroyed her ability to fight, and British torpedoes added to the fatal damage. German scuttling probably hastened the sinking, but only after the ship had already been rendered helpless. As a fighting vessel, Bismarck had been destroyed by the Royal Navy.
At about 10:40 a.m. on 27 May 1941, Bismarck sank beneath the Atlantic. More than 2,000 German sailors died. Just over 100 were rescued by British ships before reports of possible U-boats forced the rescue effort to end. Many men were left in the water, making the aftermath as tragic as the battle itself.
The sinking had great significance. For Britain, it avenged the loss of HMS Hood and removed a serious threat to Atlantic convoys. For Germany, it showed the danger of risking major surface ships far from support. After Bismarck, Hitler became more reluctant to send large warships into the Atlantic, and Germany’s naval war increasingly centred on U-boats.
The episode also revealed how naval warfare was changing. Bismarck was one of the most powerful battleships in the world, but the decisive blow came from aircraft launched by a carrier. A slow Swordfish biplane did what battleships alone might not have achieved in time: it stopped Bismarck from escaping. The final destruction was delivered by surface ships, but air power made it possible.
The story remains compelling because it contains so many dramatic contrasts: the sudden destruction of HMS Hood, the relentless British pursuit, the unlikely success of obsolete-looking aircraft, the desperate attempts to repair the rudders, and the final battering of a doomed ship that would not easily sink. Bismarck’s voyage lasted only a few days, but it became one of the defining naval episodes of the Second World War.
