You say: "when you look deeper into the subject - those citations crumble when researched properly and won't stand the test of time (i.e. Macdonalds saying about Wrede at Wagram)"

But I don't think you have conclusively proven that Wrede never uttered those words. As Susan said: "we have one piece of evidence that is about as close to the event as one can expect to get against the biographer's version of events as given by an unstated source."
