Lieutenant John Pritchard and Private Christopher Elphick, of The Honourable Artillery Company (HAC), were re-interred in the HAC Cemetery at Ecoust-St Mein near Arras in France.



Relatives of both men – who were killed on May 15, 1917, during an enemy attack near Bullecourt, while serving with the HAC's 2nd Battalion – travelled to France for the ceremony.



The men, along with two unidentified comrades, were buried with full military honours today just two miles from where they fell in Bullecourt next to the Hindenburg Line.



More than 300 people proudly attended the ceremony, including Prince Michael of Kent in his capacity as HAC Royal Honorary Colonel.



Lt Pritchard, who survived the Battle of the Somme and a gunshot wound to the neck, was killed alongside Pte Elphick when their battalion was attacked in the early hours of May 15, 1917 during the second Battle of Bullecourt.



Their remains were found in 2009 by elderly farmer Didier Guerle, along with those of two other unidentified HAC soldiers.



Lt Pritchard was identified by a silver identity bracelet, and Pte Elphick by a gold signet ring which bears his initials, but it took three years to trace their relatives.



Two further sets of remains could not be identified, but they were re-interred at the same time as "HAC soldiers known unto God".



Lt Pritchard's nephew John "Harold" Shell today laid a wreath on behalf of the family during the ceremony.



The 89-year-old, from Winchester, said it was an "incredible" experience.



"I can hardly put it into words," he said.



He said despite knowing about his uncle's death in the First World War, they never expected his remains to be found, until 18 months ago when they were informed.



"It never entered your head, after all these years why should it?



"It seems silly to say it but the feeling I had was that he is coming home. He isn't of course, but that was the feeling."



Mr Shell, who was among more than 30 members of the Pritchard family, said it was particularly emotional visiting Bullecourt, where the soldiers were killed.



"Unexpectedly to me I was completely overwhelmed, my emotions just took charge.



"I envisaged my mother who died some years ago standing there with me. It is a very strange feeling, even talking about it affects me now."
