August 11, 2025. On July 2, 2025, by Royal Decree of His Majesty Willem-Alexander, King of The Netherlands, Pieter was appointed Knight of the Order of Orange-Nassau. Created on April 4, 1892, the Order of Orange-Nassau is conferred on people who have made a contribution of outstanding value. Those who are appointed Knights have rendered meritorious service of national importance to The Netherlands.

Invitation to the July 2, 2025 Ceremony.
….The knighthood was in recognition of Pieter’s ongoing military research…
Pieter received his knighthood in recognition of the military research he’s done, and continues to do, to help ensure that Canadian soldiers buried in The Netherlands are not forgotten, and that their stories are told. The Dutch have never forgotten their Canadian liberators!

The decoration was presented by Her Excellency Margriet Vonno, Ambassador of The Netherlands to Canada, in a beautiful ceremony hosted by His Honour, Dr Wassim Salamoun, Lt Governor of Prince Edward Island.
The ceremony began with greetings by Dr Wassim Salamoun, followed by Lt Colonel Mark de Wit of the Royal Netherlands Air Force, Netherlands Defence Attaché to Canada, who described the decoration to be presented to Pieter.
“…The medal itself is a blue and white cross, topped with the royal crown. In the middle of the cross is a blue medallion with the Dutch lion. Around the lion are the French words: je maintiendrai – I will maintain, ‘ik zal handhaven’.
On the back of the medallion is the letter ‘W’, representing Queen Wilhelmina. Around the ‘W’ are the words: God is met ons – God is with us….”

In her remarks just before Pieter was presented with his decoration, Her Excellency Margriet Vonno, Ambassador of The Netherlands to Canada, began by saying “…We are all here to honour a Dutchman, and I am glad to see so many of his friends and family gathered today at the Lieutenant Governor’s residence here in Charlottetown.
Pieter is one of these people that has worked endlessly and voluntarily, for over many years now, to do something for our Canadian Liberators who did not return and lie buried in The Netherlands.
Preserving their stories and literally putting faces to graves. Not a simple task, because we all know that 80 years has passed and finding the families and information about these young soldiers is not easy….”
After listing the accomplishments that led to this honour, Ambassador Vonno concluded by saying “…Pieter, you have given all your spare time to not only preserve stories of our fallen liberators but also to promote them to a wider public. I know you continue this important work to this day and I hope you will have many more years of success. I am sure that much of this was also due to the incredible support of your wife Daria.
So it is only appropriate to thank you, on behalf of all, for what you have done all those years, and to commend you.
Dear guests, His Majesty King Willem Alexander has decided to award Pieter Anthonie Valkenburg with Knight in the Order of Orange-Nassau and it is my great honour to present the insignia of the order….”

Following his investiture, an emotional Pieter was invited to say a few words, and he began with expressing his thanks. “….I am deeply humbled by this honour, and a bit overwhelmed. Many thanks are in order. First, thank you to His Honour, Dr. Wassim Salamoun, Lt. Governor of Prince Edward Island, for hosting this ceremony. Thank you to Her Excellency, Margriet Vonno, Ambassador of The Netherlands to Canada, for nominating me for this precious decoration.
I’m grateful to everyone who wrote a letter of support, and to Wendy Sewell, Assistant Defence Attaché, who coordinated this nomination.
Last, but not least, I would like to thank my wife and soulmate Daria, who says I have a tendency to hide my light under a bushel. Her support has been tremendous. Without her, no one would know about our work…”
Pieter provided a few highlights of what happened since he began researching, and how the project has grown from a modest start in Prince Edward Island. “….I never dreamed that this small scale Island research project could have grown into a pan-Canadian research project that keeps getting bigger, and has taken me down several paths….”
In conclusion, Pieter noted that “…remembrance of those who gave their lives for our continued freedom is important, and no soldier buried overseas should ever be forgotten….”

….The honour came after a very busy trip to Europe for the 80th Anniversary of the Liberation of The Netherlands…

This recognition came on top of a busy spring, which found us in Europe for commemoration events for the 80th anniversary of the liberation of The Netherlands. Over our 5 week stay, we visited 14 cemeteries in The Netherlands and Belgium, placing small Canadian and provincial flags at 383 graves of soldiers that Pieter had researched, as well as Acadian flags, where appropriate. We’d even been sent Indigenous flags by families to be placed at the graves of 3 Indigenous soldiers. The graves were of soldiers from all 10 provinces, plus Yukon Territory.
After having placed 120 flags at the Canadian War Cemetery in Groesbeek on April 28, 2025, Pieter was pleased to see the flags still in place when we attended the May 2, 2025 commemoration service for the 80th Anniversary of the Liberation of The Netherlands at the cemetery. (See https://onthewarmemorialtrail.com/2025/07/19/on-the-war-memorial-trailwe-attended-the-ceremony-at-the-canadian-war-cemetery-in-groesbeek/)
The next day, at the grave re-dedication ceremony at the Canadian War Cemetery in Holten for WWII soldier Arthur VANANCE of Kenora, Ontario, His Excellency Hugh Adsett, Ambassador of Canada to The Netherlands, commented on how much pride he’d felt in seeing so many flags of New Brunswick, his home province, the day before in Groesbeek.
We attended the grave re-dedication as we’d been recognized by the Canadian Armed Forces Casualty Identification Program for our part in finding a family member of the soldier, and for translating documents that helped in determining that the grave of an unknown soldier buried in Holten was actually the resting place of Vanance. (Note: This story is still to come, plus more stories about our 2025 European War Memorial Tour.)
….Island media interviews …
Following the July 2 ceremony, articles about Pieter’s knighthood ran in Island newspapers: County Line Courier, The Guardian, and by Josh Lewis of The Eastern Graphic. Pieter also was interviewed on CBC PEI Radio’s ‘Island Morning With Mitch Cormier’ by Taylor O’Brien.

….Previous recognition…
This was the second honour this year from The Netherlands! In May, we received a Certificate and a Faces To Graves ‘coin’ by the Faces To Graves Groesbeek Foundation for their research into Canadian soldiers buried in the Canadian War Cemetery in Groesbeek, and for finding families and sharing photos of over 100 of the soldiers.
Pieter has also been recognized here in Canada, most recently in 2024, when he received the Minister of Veterans Affairs Commendation. (See https://onthewarmemorialtrail.com/recognition/)
Now that the excitement of receiving a Knighthood is over, the research work continues for Pieter, and we’ll continue to share the highlights of our adventures on the 2025 European War Memorial Trail on our journey of remembrance.
If you have photos or information to share about soldiers buried in The Netherlands or Belgium, please email him at memorialtrail@gmail.com, or comment on the blog.
