Last battle of Bismarck

• 1. Operation Rheinübung Prelude

  ›

  The German battleship Bismarck and the heavy cruiser Prinz Eugen attempted to break out into the Atlantic Ocean on the 19th of May 1941. Fleet Commander Günther Lütjens led this operation with a clear goal: disrupt convoys traveling from North America to the United Kingdom. The ships faced immediate interception by British forces from the Home Fleet during the Battle of the Denmark Strait on May 24. Damage sustained in that battle included flooded machinery compartments and damaged fuel tanks. Captain Lütjens intended to reach the port of Brest for repairs but found his path blocked. Fuel became a major concern as the ship failed to refuel in Norway or via tanker while underway. Lütjens chose an economical speed of 21 knots to conserve remaining fuel reserves. On May 25, he broke radio silence to send a coded message to Germany. This decision proved critical because British forces overheard the communique and triangulated the Bismarcks approximate position. They deduced the German battleship had set course for France rather than returning to Norway. By early evening on May 26, a Coastal Command Catalina reconnaissance aircraft spotted the ship. Flying Officer Dennis Briggs piloted the plane from its base at Lough Erne in Northern Ireland. Ensign Leonard B. Smith served as co-pilot and US Navy observer. He spotted the vessel through a trailing oil slick from the damaged fuel tank. The American reported her position to the Admiralty shortly after detection.

• 2. The Critical Swordfish Strike

  ›

  At 14:50 on May 26, HMS Ark Royal launched fifteen Swordfish torpedo bombers under poor weather conditions. These aircraft were not warned that the light cruiser Sheffield shadowed the Bismarck nearby. Initial attacks targeted the wrong ship due to confusion about available assets. Torpedoes with defective magnetic pistols exploded upon impact with the sea surface. Remaining torpedoes could be evaded by the German battleship. At 19:10, the same aircraft were relaunched for a second sortie using contact pistol torpedoes instead. First contact occurred at 20:00 when the Swordfish vectored toward the target via the shadowing cruiser. Despite having ASV II radar systems, they failed to locate the enemy initially. Half an hour later, they recontacted the Sheffield which finally directed them correctly. The attack began at 20:47 and lasted approximately thirty minutes. Three aircraft had to recontact the Sheffield for a third time before finding their mark. A first hit midships produced little effect but a second strike astern jammed the rudders twelve degrees to port. This resulted in the ship being forced into large circles rather than straight lines. Repair efforts by the crew to free the rudder failed completely. Bismarck attempted steering by alternating power among three propeller shafts. In prevailing force eight wind and sea state conditions, this maneuver drove her directly toward pursuing British battleships. At 23:40 on May 26, Admiral Lütjens delivered a signal stating Ship unmanoeuvrable We will fight to the last shell Long live the Führer.

• 3. Night Harassment Tactics

  ›

  One hour after the Swordfish attack, destroyers Maori and Piorun made contact with Bismarck at 22:38. Polish destroyer Piorun attacked immediately while signaling identity as a Polish vessel. She approached close enough to engage with guns but lost contact shortly thereafter. Deteriorating weather prevented any concentrated attacks throughout that night. Throughout the darkness between 22:38 and 06:56, Cossack, Maori, Zulu, and Sikh fired sixteen torpedoes total without scoring hits. One of Bismarcks shells sheared off Cossacks antenna while three others straddled Zulu wounding three men. Between 02:30 and 03:00, destroyers fired starshell upon Toveys request to make position visible for incoming battleships. Constant harrying tactics wore down German morale significantly. Fatigue deepened among an already exhausted crew during these hours. Between 05:00 and 06:00, Lütjens ordered an Arado 196 floatplane launched toward French coast. The mission aimed to secure war diary documents footage from engagement with Hood and other important materials. Discovery revealed catapult had been rendered inoperative due to damage received on May 24 by Prince of Wales. Fully fuelled aircraft was pushed overboard to reduce fire risk during upcoming battle. At 07:10, Lütjens radioed U-boat U-556 to rendezvous fetching documents. U-556 missed signalled order because it remained submerged at that moment. It was subsequently revealed U-556 lacked sufficient fuel to carry out assigned task. Task passed to another unit but Bismarck had already sunk before arrival.

• 4. The Final Surface Engagement

  ›

  Morning Tuesday May 27 brought heavy grey sky rising sea tearing northwest wind. Gale force conditions made final attack undesirable until clear daylight arrived. Norfolk became first ship sighting Bismarck on morning of May 27. Cruiser stumbled upon unidentified vessel flashing recognition signals before realizing target was German battleship. Norfolk quickly turned away making contact with British battleships before joining final phase. Lookouts aboard King George V spotted Bismarck approximately ten miles distant at 08:43. Rodney opened fire first at 08:47 followed quickly by King George V. Unable to steer properly due to torpedo damage rudders created unpredictable motions making gunnery extremely difficult. Gale force storm further complicated shooting accuracy despite efforts. Bismarck returned fire at 08:50 using forward guns second salvo straddled Rodney closest hit scored during entire engagement. At 09:02 a twelve-inch salvo from Rodney struck forward superstructure damaging bridge main fire control director killing most senior officers present. Forward main battery turrets also damaged by same impact. Aft fire control station took over direction aft turrets receiving three salvos then neutralized completely. With both stations out action shooting became increasingly erratic allowing British close range safely. Around 09:10 Norfolk fired four torpedoes Rodney six more from distance exceeding ten kilometers none observed hitting target. By around 09:31 all four main battery turrets were out of action entirely. First Officer Hans Oels issued order scuttling ship ceasing damage control measures opening watertight doors preparing charges ordering crew abandon ship. Shell from King George V penetrated upper citadel belt exploding aft canteen killing Oels about hundred others around 10:00. Gerhard Junack senior surviving engineering officer ordered men set demolition charges nine minute fuse intercom system broken down sending messenger confirm orders never returned. Junack primed charges ordering engineering crew abandon ship immediately.

• 5. Scuttling and Sinking Mechanics

  ›

  Once all four main battery turrets disabled around 09:31 Rodney closed within point blank range firing guns directly into Bismarck superstructure. King George V maintained greater distance increasing possibility plunging shells strike decks vertically penetrating interior spaces. At 10:05 Rodney launched four torpedoes claiming one hit confirmed later examination. By 10:20 British battleships running low fuel reserves while Bismarck settling stern taking twenty degree list port side. Tovey ordered Dorsetshire close torpedo crippled vessel allowing King George V Rodney disengage safely. Torpedo attacks took place when deck partly awash due to severe listing. Dorsetshire fired pair torpedoes starboard side one hitting successfully moved around port side firing another also striking home. Last torpedo appears detonated against port side superstructure already underwater based subsequent wreck examination. Beginning capsizing approximately 10:35 slipping beneath waves stern first by 10:40. During engagement two British battleships fired some seven hundred large caliber shells total collectively fired around four thousand shells scoring approximately four hundred hits. Progressive uncontrolled flooding caused ship settle rapidly despite attempts save her. Damage control measures ceased after orders issued by First Officer Hans Oels. Engine room personnel prepared scuttling charges but messenger sent confirm orders never returned. Junack primed charges ordering engineering crew abandon ship immediately without waiting confirmation. Final sequence led directly to submersion within minutes following last torpedo impact.

  Dorsetshire picked up eighty five survivors Maori rescued twenty five others from water. At 11:40 lookout aboard Dorsetshire thought spotted periscope abandoning rescue effort leaving hundreds still floating. Midshipman Joe Brooks jumped over side helping wounded Germans scramble up ships side. One sailor lost both arms hanging rope teeth Brooks tried saving him failed. Nearly left behind when U boat alarm given pulling away while still in water thrown line shipmates pulled aboard safely. After battle British warships returned United Kingdom carrying one hundred nine Bismarck survivors. One survivor Gerhard Lüttich died wounds day after rescue buried sea the 28th of May 1941 full military honours crew HMS Dorsetshire. That evening nineteen thirty picked three survivors dinghy Herzog Höntzsch Manthey next day twenty two forty five German weather ship Lorenzen Maus picked two raft survivors neutral Spanish heavy cruiser arrived scene finding none. Out crew over two thousand men only one hundred fourteen survived total loss life among German ranks devastating blow morale. Rescue efforts halted prematurely due apparent submarine threat sighting causing abandonment many still struggling water surface. Tragic outcome reflected broader strategic failure experienced by German navy during operation Rheinübung.
