This is a slightly retouched photo of Klaas Siersema, second from the bottom right, and his fellow Royal Netherlands military officers on July 15, 1940. At this time, judging by the stars on Klaas’ collar, he had achieved the rank of captain.
On the back, it says that these are the officers of the battalion that Niek commanded, according to a translation my cousin Anje Belmon graciously did.
Unfortunately, I have no way of knowing who Niek was. Update: About a week following this post, I listened to a 1980s audio interview my mother, Joy Siersema, did with my grandfather and Klaas’ son, Johan Siersema. From the interview, I learned that Klaas went by Niek, so these would have been the soldiers under his command.
As for who the other officers are, the writing on the back of the photo has some clues. The wording, as best as I can make out, reads: “n.d. Sluis – Roos – Tiele – ‘t Mannetje – van der Beek – unreadable – unreadable – van Dok – Boekholt – Schul – van Boal – unreadable – van den Tut.”
The writing on the back also notes that four men are missing from the photo. Their last names were — again as best as I can make out — Ter Hal, Nahuiser, Schiere and Meyer.
Trust me, though, the names are not easy to read! So if you see something different from what I’ve written here, please leave a note in the comments and I can update the tags so if any descendants of these gentlemen are searching for them, they may have a better chance of finding this post.
