It's an interesting question and we will probably never know for sure...
But what we tend to forget is - as time goes by - historical events (like WWII) are sometimes thought of as a constant, uninterrupted chain of 'action' (invasion->war->defeat), but if you think of the actual time span in minutes, days, weeks, surely - even when it was clear that the TR was doomed - for some civil servants or military administrators it was business as usual for days, weeks and even months. The best way of denying the inevitable outcome is to concentrate on the more manageable bureaucratic job right in front of you...
