I find it amazing that the Blenheim soldiered on so long as it did. After the Fall of France the Battle was shifted to other duties as soon as possible, yet the Blenheim, which fared just as badly continued on in frontline service. Once the Beaufighter was shown to be a success production should have shifted to it in place of both the Blenheim and Beaufort. It could fill the Night Fighter, light(ish) bomber and torpedo bomber roles better than either of them.
