What if after the sinking of the HMS Hood Admiral Lutjens did not permit the Prince of Wales to retreat after the battle of the Denmark Strait but instead kept attacking the PoW sinking her, and decided to port in either Brest or retreat back to Norway back up the Denmark strait?

To what extent would the British go to sinking not just the Bismarck but Tirpitz as well, and what affect would this have on German shipbuilding?
