Interesting cause of death. I always wonder how the war would have been if the Bismarck had not been sunk so early.
Not sure it would have made much difference? Keeping the Bismarck in port (in Norway, for instance) would have required constant surveillance. Whenever it broke for the open ocean, the results would have been pretty much the same.
It would have tied up a lot of British naval assets checking it, but it would also have tied up a lot of German anti-aircraft assets defending it.
I wonder how the War would have gone had the Germans used their submarines (their most effective weapon) more effectively (and ruthlessly) earlier in the War.
Hitler's meddling in strategic (and tactical) decision making did the Germans an enormous amount of damage.
