The battleship Bismarck was really sunk.

Let me tell you something. Brain-dead Nazi fans say Bismarck sank himself. In fact, this evidence also comes from the investigation of Bismarck's remains by the deep-sea expedition in the movie Titanic. After the detection and data analysis of the Bismarck shipwreck, they synthesized the so-called high-definition photos, saying that the main armor belt was not punctured, so it was self-sinking.

That's actually how brain-dead Nazi fans say it. I have no dispute about this expedition, but the conclusion is obviously wrong. Not to mention that the harsh seabed environment can only indirectly detect synthetic photos, which will inevitably lead to many details being ignored and distorted, and it is impossible to restore the real situation. Let's take the main armor belt. The main armor belt cannot be sunk without being penetrated by the battleship. Joke, not to mention that there are still many parts of the battleship that cannot be covered by armor belts, at least consider torpedoing the underwater part. Ten thousand steps back, even if Bismarck sank, according to the brain-dead Nazi rice. You should know that the Bismarck, which had died under British siege, was hopeless, so it sank by itself to avoid being killed by the British and breaking into pieces. What is the essential difference between the two?
