Hi AOK4,
That is very interesting, because according to 'The Jasta Pilots', Jasta 36 was never part of Jagdgruppe 4. Jastas 2, 26 and 27 had just left this gruppe on Febuary 2 to form Jagdgeschwader III commanded by Oblt.
Bruno Loerzer. Jasta 36 was at various locations, but Bisseghem was not one of them (as far as what is listed in this book). Jasta 47w bounced around to many other Jagdgruppe for the rest of the war.
I would expect that your document would be accurate, as it is a period document. I wonder if anyone can explain this discrepancy?
regards
