Why Hitler's Most Powerful Battleship Ever Refused to Sink

On May 24, southwest of Iceland, Bismarck and Prinz Eugen tangled with the battleship HMS Prince of Wales and the aging battlecruiser HMS Hood. Trading armored protection for speed, Hood’s designers had left it dangerously exposed to enemy fire. Hits from the German task force ignited an ammunition fire that raged out of control on Hood. Within ten minutes a titanic explosion shook the Denmark Strait as the fire reached the aft magazine. Hood broke in half and sank, taking 1,418 men with it.

Bismarck, despite its stunning victory, had not emerged from the battle unscathed. Hit three times by Prince of Wales, it lost some of its fuel supply to seawater contamination, sustained damage to its propulsion, and suffered a nine-degree list to port. Its captain, desperate to get away from the site of the battle and a slowly coalescing Royal Navy force eager for revenge, refused to slow down to allow damage control to effect repairs.

On May 23, 1941, the Battleship Bismarck was on a roll. The largest and most powerful ship in the German Navy, the mighty Bismarck had broken out into the Atlantic Ocean, sunk a Royal Navy battlecruiser, badly damaged a battleship and was poised to add its guns to a naval blockade that threatened to strangle Great Britain.

Ninety-six hours later, heavily damaged, the battleship was on the bottom of the North Atlantic. Bismarck’s swift reversal of fortune was the result of a heroic effort by the Royal Navy to hunt down and destroy the battlewagon, and avenge the more than 1,400 Royal Navy personnel killed in the Denmark Strait.

The German battleship Bismarck was the the pride of the Kriegsmarine, Nazi Germany’s naval service. Construction began in 1936, and the ship was commissioned in April 1940. It and its sister ship, Tirpitz, were 821 feet long and displaced fifty thousand tons, making them by far the largest warships ever built by Germany. Despite its size, twelve Wagner steam boilers made it capable of a fast thirty knots.

Like any battlewagon, Bismarck’s firepower lay in its main gun batteries. Bismarck had eight fifteen-inch guns in four large turrets, each capable of hurling a 1,800-pound armor-piercing, capped projectile 21.75 miles. This gave it the ability to penetrate 16.5 inches of armor at eleven miles.

The relatively small size of Germany’s World War II navy made it incapable of taking on the British and French navies head-on. Instead, the Kriegsmarine was given a much more limited role, of shepherding invasion fleets and cutting off the flow of commerce to Great Britain. On May 18, 1941, Bismarck and its escort, the heavy cruiser Prinz Eugen, embarked on Operation Rheinübung, a campaign to sink Allied shipping in the North Atlantic and knock Britain out of the war.

Its captain, desperate to get away from the site of the battle and a slowly coalescing Royal Navy force eager for revenge, refused to slow down to allow damage control to effect repairs.

Bismarck’s captain was correct. The Royal Navy was assembling a large force to sink it, and indeed had ordered every ship in the area to join in the search to find it. The much larger Royal Navy was able to assemble a force of six battleships and battlecruisers, two aircraft carriers, thirteen cruisers, and twenty-one destroyers to hunt Bismarck. Unfortunately, many of the larger ships were of World War I vintage, and could not catch up with the wounded, but still fast Bismarck.

Although Bismarck outclassed nearly all the heavy capital ships that chased it, naval aviation was another matter. The German task force’s location was betrayed by oil leaking from the battleship and the aircraft carrier HMS Victorious was sent to slow it down. An air strike by six Fairey Fulmar carrier-based fighters and nine Fairey Swordfish carrier torpedo bombers managed a single hit on Bismarck. The torpedo explosion did minor damage, but the evasive maneuvers conducted by Bismarck’s captain to evade the torpedo attack caused even more damage, slowing the mighty battleship to sixteen knots.

Although it was eventually able to get back up to twenty-eight knots, the temporary loss of its speed advantage allowed a Royal Navy task force, Force H, to catch up to it. Established to take the place of the surrendered French Navy in the western Mediterranean, Force H was based at Gibraltar. It consisted of the aircraft carrier HMS Ark Royal, the battlecruiser Renown and a light cruiser.
