[Franek Grabowski]

I repeat, it was well known years before Emmerling published his books and articles, that Mazurowski was downed by Januszewicz.
The claim that Polish reports and accounts were filed years after events is just as ridiculous as the claim that there are no period Polish documents around (interestingly Emmerling denies himself in his post). Cynk's book is about Polish Air Force and not the German one, and despite few minor flaws it is still state of the art on the subject.
