Ely’s warship and its secret mission to retrieve diamonds from Holland

A researcher is piecing together the story of a remarkable operation that took place at the beginning of the Second World War - involving a warship with connections to Ely.
The mission involved HMS Walpole, the destroyer adopted by Ely after the community invested £559,000 of their own savings during “Warship Week” campaigns in 1940 and 1942. In today’s money, that’s close to £31.5 million.
But as she was introduced to the people of Ely, HMS Walpole assisted three men who had to get to Amsterdam as the Nazi’s were invading Holland.
A hub for diamond trading, their mission was to bring back industrial diamonds which could’ve been used to manufacture weapons and war machinery,
“If the Nazis managed to get hold of those diamonds it would’ve considerably strengthened their position in the war,” says Darron Wadey, who is piecing together the mission.

Darron is British and lives in the Netherlands, close to Amsterdam. He is a military history enthusiast researching ‘Operation Amsterdam’. And with no official records available about the mission, it’s certainly a challenge.
Hitler invaded Holland on Friday, May 10 1940. Winston Churchill was running the country as Prime Minister the next day, and HMS Walpole had to reach the Dutch coast at IJmuiden on the Sunday evening to transfer the men.

Darron said: “The sea lanes were very busy and HMS Walpole would’ve been travelling against the flow. Everyone was fleeing the country, including the Dutch royal family, diplomats and refugees.
“On the way over, it’s understood she had a near miss with the ship carrying the Crown Princess and her family - but we haven’t been able to confirm this in official sources.”
He added: “It certainly would’ve been chaotic in IJmuiden.
“There was no air cover and the Dutch were trying to coordinate their defence and the evacuation of people and property.
“The Dutch air force had been wiped out on the opening day of the invasion and there was the ever present menace of the German Luftwaffe in the skies.
“On the Monday morning, a passenger liner carrying 150 people fleeing also hit a mine and sunk - it was an incredibly dangerous place to be.”
Even so, the three men - Jan Smit, Willem Woltman and Lt Col. Montagu Reaney Chidson - disembarked to carry out a mission they had less than a day to complete.
Smit and Woltman were Dutch employees of JK Smit & Zonen of Amsterdam - one of the largest diamond traders - and were based in Britain. Smit’s father Johan ran the enterprise from Holland.
Lt Col. Chidson was previously with Section D of MI6 and had connections from serving in the First World War. He had also been a diplomat at The Hague.
His obituary in The Times describes the mission by saying: “... at every turn was attended by great hazards.”
It said: “A British destroyer was placed at Chidson’s disposal and got him and his companions as near to the Netherlands as was then practicable. Thence they travelled by a car provided by the Dutch government.
“Once in Amsterdam, he was able to find that his years of service in Holland had by no means been wasted.”
The trio returned to HMS Walpole “bringing with them what they sought” - and three bottles of Napoleon brandy.
Stories passed between crew members suggest the Dutch Crown Jewels were also among the diamonds - but no official sources confirm this.
The obituary continues: “It was with some difficulty that a tug master was persuaded to venture out into the mine-infested waters and with greater difficulty persuaded to wait for the destroyer, which was late for the rendezvous.
“After a delay that must’ve been as much of an ordeal as all that had gone on before, the vessel arrived and Chidson climbed the Jacob’s ladder up the side, bearing a sack upon his back rather more than £1,250,000 of diamonds.”
The mission was dramatised in a book ‘Adventure in Diamonds’ by David Walker, and further exaggerated in the film ‘Operation Amsterdam’ starring Peter Finch and Tony Britton.
While Darron is researching the real story from the Netherlands, he has come across several blocks.
Recently, for example, he made contact with JK Smit Diamond Tools and discovered their historic documents were destroyed when their predecessor company went bankrupt.
“It’s in keeping with this story that documentation is hard to come by,” Darron said.
