They call it the Honour Run. Each year serving and former soldiers from different countries visit war cemeteries in the Netherlands and Germany to pay their respects to those who died in the Second World War.
However, it is a separate ceremony from Remembrance Sunday, held earlier in the year and also strikingly different.
A convoy of more than 100 leather-clad bikers from the Army Vets Motorcycle Club visit Reichswald Forest, the largest Commonwealth war graves cemetery in Germany, every year.
More than 7,500 Second World War servicemen are buried there.
