24 September 1939: GC II/4 vs JGr 152 and I./JG 53

[Laurent Rizzotti]

Several French books indicated that during the battle in the afternoon of 24 September 1939 between GC II/4 and JGr 152 and JG 53, the French shot down two Bf 109. Everyone agrees that Oblt Borth of JGR.152 was shot down by Adj Dardaine, but the Bf 109 claimed shot down by Adj Camille Plubeau is given in the above sources as from I./JG 53, pilot claimed.

Problem is that in neither of these losses this pilot is identified (while other are) and there is no JG 53 loss this day in Peter Cornwell's "Battle of France then and now".

On the other hand, depending of sources, German claimed two victories in this battle (by Lt Elstermann and Lt Grasser of JGr.152), or three (by Fw Walter Czikowsky and Uffz Albrecht Baun of 6./JG 53 and Lt Walter Rupp of 1./JG 53). One Curtiss (n°66) was shot down and two damaged.

I have the following questions:
1) can someone confirm that JG 53 did suffer a loss in this battle ?
2) did the JGr 152 claim victories in the battle against GC II/4, or in the battle against GC I/3 before the same day ?
3) do anyone know the crash place of the shot down Curtiss (in my sources, it is just indicated that the pilot, Sgt de la Chapelle, bailed out and landed 800m from German lines) ?

Thanks in advance
