So what if during the Battle of the Denmark Strait, the Bismarck sinks the Hood as well as the Prince of Wales.
I assume the hunt for the Bismarck goes pretty much the same, and I would also assume that this does not butterfly away the Indomitable running aground, which basically leaves Admiral Philips with the Repulse.
Do you think he would still try to sail into Malaya and try to catch the Japanese landing forces off-guard? While the Repulse was an older ship, the crew was apparently better trained and the skipper, Bill Tennant was also an extremely good officer. Could the even bigger success of the Bismarck convince Philips that he can sail out with Force Z?
