    I cannot imagine how scary it is when you technically can&apos;t see anything in a do or die fight.

    It‘s kinda warming how the men of HMS Venturer, despite being the first submarine to sink down another submarine in combat, didn’t celebrate over the deaths of 70 fellow sailors of U-864, even when it‘s the Germans delivering top-secret blueprints and materials to Japan. It just shows that the code of conduct amongst sailors of both sides is very honorable. This is also reflected in the Laconia incident as well.

    By the way, HMS Venturer also sank U-Boat U-771 on 11 November 1944, and between &apos;44 and &apos;45, it also sank five merchant ships and three more Axis vessels. It remains the only sumbarine to sink another when both were submerged, which foiled Operation Caesar, the mission U-864 was critical for. This is actually the only entirely underwater naval engagement in history.

    Operation Caesar (U-864) was Germany&apos;s last-ditch tech transfer to Japan in early 1945. The cargo: Me 262 jet engine parts and Jumo 004 turbojet plans, V-2 missile guidance systems, and ~65 tons of mercury for weapons production — plus Messerschmitt engineers and Japanese specialists onboard to put it all to use. The Allies had cracked the codes and knew it was coming. HMS Venturer tracked it by hydrophone alone and sank it with all 73 aboard — the only time one sub ever sank another while both were submerged.

    Interesting how the torpedo managed to hit a diving sub when they are supposed to be set at a certain depth.

    This is a critical moment, not only was it historical first, it was a turning point to forbid Japan to get hold of those technology!

    Actually been following this one really closely for years, so just a small correction: capping didn&apos;t actually start in 2018. What happened in 2016 was a temporary support fill to stabilize the wreck area, and in October 2018 the Norwegian Coastal Administration decided to go ahead with capping as the chosen method. No actual capping has ever started.<br><br>As of 2026 the wreck is still just sitting there. Over 350 million NOK has been spent on studies and reports and they&apos;re still going in circles. In autumn 2025 Forsvarsmateriell published a report recommending full raising of the wreck because capping would likely cause the live torpedoes to eventually detonate and scatter mercury everywhere. Then just weeks ago FFI published a different report saying the torpedoes are fine and can tolerate capping. Two branches of the Norwegian defence establishment now contradicting each other. The Storting voted this year to force a reassessment.<br><br>23 years since the wreck was discovered and no remediation has happened. It&apos;s a bureaucratic nightmare and the mercury is still slowly leaking the whole time.

    @Yarnhub - please check this great war-time story too: &nbsp;<br>In 1939, as Germany and the Soviet Union invaded Poland, the crew of the Polish submarine ORP Orzeł chose to escape rather than surrender. After being initially attacked, they fled to Estonia, where the submarine was impounded because their captain required surgery. Refusing to give up the ship, Chief Officer Jan Grudziński staged a mutiny, took two Estonian guards hostage, and set sail for Britain. Without confiscated navigational charts or a radio, they navigated solely by lighthouses and survived fire from both sides across the North Sea. They miraculously reached Scotland, shocking the British who believed the submarine was lost. During the perilous journey, they made one brief stop in Sweden to peacefully release the hostages, giving them money to travel home first-class.
