90 year mystery of soldier riots
They lie amongst 85 of their Canadian comrades who were buried at St Margaret's church in Bodelwyddan during World War I.
But these five soldiers were not killed battling the enemy or by the flu pandemic that claimed the lives of many of their fellow troops.
They were killed during riots in the town's Kinmel Camp in March 1919 after the war - and their deaths are still shrouded in mystery and confusion.
Despite much interest, historians still do not know exactly what happened and who killed the five men.
They also fear more people could have died in the riots than the official figures show.
But as the 90th anniversary of the riots is marked, researchers say they are still waiting for a complete answer.
George Owen, from London, who has researched the riots, said: "Ninety years on five graves at Bodelwyddan Churchyard are still the subject of some mystery.
Research into the riots has revealed that on March 4, 1919, a two-day riot kicked off in Kinmel Camp, where around 17,000 Canadian troops were being held waiting to be returned to Canada after the war.
Mr Owen said that following months of delays in being repatriated to Canada, the soldiers, who were living in overcrowded conditions, suffering a severe winter and some dying of flu, started a two-day rebellion which left the five men dead and another 28 injured.
He said a former Canadian corporal, Chester Arthur Greenfield, who was present during the riots, revisited the graves in 1978 and said that the officers kept promising the men they could go home.
The Canadians eventually became angry when they discovered that ships earmarked for them were sailing back to America with US soldiers on board, many of whom had apparently not seen action during the war.
