Question

How would history change if a T-class submarine sank Bismarck before the Battle of the Denmark Strait?

Short answer

The T class and Royal Navy Submarine Service would gain lasting fame, while later arguments about Bismarck would focus on an ambush that denied her a surface battle.

Notes

The immediate operational result is less important here than the historical reputation created by the sinking. The successful T-class boat would be immortalized for destroying Bismarck, while complaints would likely follow that the German battleship never received a fair surface fight because she was caught by an ambush. The episode would also make it much harder for popular history to overlook the Royal Navy Submarine Service's wider World War II record.
