Thanks for posting the photos, Eric. As I told you, they are quite a rarity. In my opinion, they are taken on 12 May 1940, due to the lack of badges, EKs and RKs, mainly, but also because of the bandage on the chin of the FJ in photo 8: it�s a trace of a recent wound... It seems that they are crossing the border between Holland and Germany or, perhaps, entering in K�ln barracks (difficult to say for sure...). We have to bear in mind that the men of Stab. Koch were awarded the EKII on that day; the day after, the EKI (at least for the members of Granit. As Ian does know,there are certificates of the EKI dated on 15 or 18 May...); The RK, 16 May.
As for my initial doubt, namely, the identity of the officer saluting on photo #4, I�m most convinced that he�s Olt. Kiess.
Best regards. �scar
