Many thanks Salzburg Surf Scene for the info, much appreciated. Such a shame that more hasn't been written.
With regard to the supposed inaccuracies, I imagine each author (including Mark Moore) is convinced that their work is 'the definitive story' based on the understanding that they think they have. However the 'real' definitive story is with those that were involved and this may never be revealed, unless it comes from them 1st hand, and even then who can say what they reveal is true?
When it comes to writing history, nothing is ever "definitive" . . . That's a tired cliche and falsehood that writers, publishers, reviewers, and critics perpetuate.
And this is inclusive of "professional historians" . . . meaning people who obtain Master's Degrees and Ph.D.s in History, who then teach for a living, and who are then pressured to publish in their fields of study, in an effort to gain "tenure" with their respective employers (universities).
Nevertheless, contemporary documentation (in all its many forms), will always trump the decades-old memories and stories of primary players in any story . . . which, taken by themselves, are always skewed and embellished to present the story-teller in the best possible light (while sometimes disparaging others).
The best approach is to study period documentation (in all its forms), while interviewing as many living witnesses as possible, and then comparing it all to see what adds up and what doesn't. That's the key, and there will always be unanswered questions.
Sometimes, you can cite period documentation that will jog the memories of key players . . . and you can strike gold in the process.
At the same time, you can also debunk a lot of falsehoods and cut closer to the heart of the matter. But it takes perusing and studying many sources to get there. Not just accepting the filtered and biased memories of those who were "there."
