Why Prince of Wales should not ram Bismarck

Should Prince of Wales have tried to ram Bismarck after her gun problems at Denmark Strait?

No. It might destroy Bismarck, but probably at the cost of Prince of Wales, turning the battle into an unnecessary two-capital-ship loss.

A successful ram might disable or sink Bismarck, but it would probably destroy Prince of Wales as well. After Hood's loss, that would turn the action into a two-for-one capital-ship exchange. Britain could afford a one-for-one trade more readily than the loss of both British ships. The tactically decisive act would therefore be strategically unsound.
