The crematorium in the Natzweiler-Struthof concentration camp as it looks today, preserved as a warning to future generations. A British Military Court, convened in June 1946 in the Zoological Garden at Wuppertal, found five men guilty of Sgt Habgood’s murder.One was given a term of imprisonment, the four others faced death sentences. Two sentences were later commuted to imprisonment and the remaining two men, whose names are known but do not deserve to be remembered, were hanged in October 1946. A year later, to the day, NE 164 was shot down, and Freddie Habgood’s voice fell silent.He speaks again now, and we remember him, through a bracelet emerging from the earth. Light shining from the darkness. In the late evening of July 28, 1944, an air armada of 494 RAF Lancaster bombers took off from eastern England to attack enemy targets on the continent.One plane, tail number NE164, launched from an air base in North Killingholme near Grimsby. The target was the industrial area of Stuttgart, but the bomber never made it through.At 01:32 on the morning of July 29, NE164 was attacked by a German Messerschmitt, piloted by Oberleutnant Gottfried Hanneck of No. 1 Night Fighter Wing.With the right wing of the aircraft on fire, Flying Officer Harry Jones steered his plane past the small town of Obernai in the Alsace region and at about 01:50 the Lancaster crashed in a forest.Of the seven crew, F/O Jones died in the crash and Sergeant Idwal Williams, one of the two Gunners, did not survive his parachute jump.The Wireless Operator Sergeant Donald Hunter, Flight Engineer Sergeant James Drury and Gunner Sergeant Roy Cumberlidge were taken prisoner and survived the war in a camp in Poland.Navigator F/O William Dinney, a Canadian, hid in a nunnery and was handed over to the Resistance who helped him escape back to Britain.Sergeant Frederic Harold Habgood, the plane’s bomber, was betrayed by a local woman to the Gestapo. On July 31 he was taken to the nearby Natzweiler-Struthof concentration camp and immediately hanged. He was 21 years old. Freddie had been survived by his brother, Ronald, older by 13 months, and younger sister, Madelene. Ronald had two children, Marilyn and Paul, but the family had rarely discussed their loss.“Growing up, all we knew was that Freddie had been killed during the war,” says Marilyn, “it wasn’t until I was quite a bit older that I realised he had actually been executed”.“It was never really spoken about. Certainly my father didn’t want to talk about it.”The Telegraph accompanied Marilyn and Paul to France to be reunited with the bracelet. Up to that point they say the story of their uncle had been part of the family fabric, but as neither had known Freddie personally, and his death had been so little talked of, there had been no direct emotional connection.That changed in France.

She had expressed a wish that the bracelet be offered to a museum in Britain. “We would like to have it back here as a family. We would like it to go to a museum for everybody to see,” Marilyn and Paul agree.Freddie had written to his parents on July 29, 1943 from Canada, saying how much he had enjoyed his time with his uncle Harry and aunt Gladys, and of how they had given him his silver bracelet.‘My dearest mum and dad,’ he wrote, ‘I was able to visit aunty Gladys and uncle Harry for a few hours. They gave me a bracelet, with RAF wings and name and number engraved, for a graduation present. I was very sorry to say goodbye and hope that I shall be able to see them again after the war.’ Freddie Habgood had trained in Canada throughout 1943. He had relatives in the country, and for his graduation they had given him a gift of a silver bracelet engraved with his name, service number and RAF wings. On the reverse was one name, Jean, Freddie’s beloved cousin. His family assumed it had been stolen by the Nazis after his murder.In July this year, as she watered the flowers at the concentration camp in France, preserved as a warning to future generations, a local girl saw something glinting in the soil. Although muddy and tarnished, some lettering was still clear and two names were visible. On one side ‘Jean’, on the other, ‘Habgood’.It had not been looted by the Nazis. It had not been consumed by fire or by earth.Incongrously, incredibly, for 74 years the ground had kept the secret of Freddie’s silver bracelet, and now the soil had offered it up.
