I have no doubt what you posted is accurate and that her wartime service was a myth...but perhaps it was just the myth the English people needed at that time. When it comes to creating myths and legends to provide much needed morale and rally people to a cause, the English are hardly unique, just possibly more skilled than most.
I agree and it seems it was handled very nicely for the British war public but being realistic and truthful is more than called for long after the war and is a must for Americans and American conservatives above all.
People can’t go around thinking she was an actual WWII school trained army auto mechanic and driving around alone on the streets of wartime Britain.
