"The historians all refer to the sad fact that the general population still believe the old discredited myths."

Is it just barely possible that the reason for that is that the general public are correct, or are you now claiming that the general public are too ignorant to know what is going on?

I seem to remember you having difficulty with that concept when it related to farm labourers, who made up the bulk of Haigh's cannon fodder.

Maybe those historians aren't the only ones in the army who are in step.

Maybe they are the ones who aren't, and the "discredited myths" are the truths they are trying to hide.
