Rather than Alex, nor even James Arnold, it is most likely such phrases fall from a publicist at the publishing house whose knowledge of history doubtless stops with Fox.

It is a requirement of any new book that it claims to overturn myths and offer a radical new view or re appraisal of events - even when there are no myths nor re-appraisal needed.
Usually it also has to be done 'through the eyes of the common soldier' too, even when its a book about strategy, seems we have been spared that this time in favour of multiple myths.
I'll wait to see what the author actually says.

Perhaps shoot the publishers not the messenger.
