By mid-morning, the crowds are lining Meensestraat several deep to get a glimpse of the veterans' parade and service beneath the Gate. Joining the townsfolk and the largely British visitors are the immaculately turned out veterans. Hundreds of bereted Brits, Belgians, Kiwis and Canadians, as well as Indians in yellow turbans. Medals glimmer and helmets shine in the oozing rain. Waxed moustaches bristle to attention. Those unable to get near the Gate gather under umbrellas in front of a giant screen in Grote Markt.

Benoît Mottrie is chairman of the Last Post Association, which organises the town's daily honouring of the war dead. Every evening at 8 o'clock, the traffic is stopped beneath the Menin Gate to allow the buglers to sound their mournful tribute.

The clock sounds 11 o'clock. Mottrie gives a moving speech in which he rebuffs recent suggestions that with the Great War receding from personal experience into distant history, it may be time to review the daily act of remembrance. They have sounded the Last Post 27,569 times since 1928, he reminds the crowds. Were they to sound it for every life lost, they would be busy until 2610.

"It is only right and proper that sacrifice on this scale should be remembered," he says. "Our debt of honour to the past has not yet been paid." It will be properly discharged "only when people learn to resolve their differences peaceably".

One by one, suited dignitaries lay wreaths in the heart of the memorial. The Gate is flanked by an expanse of sodden, scarlet poppies, a "Flanders Field" organised by the Royal British Legion. The famous lines from Laurence Binyon's Ode to the Fallen - "At the going down of the sun, and in the morning / We will remember them" - are written on the petals, with messages of support on the back. "May we never forget your sacrifice and hope that men soon cease to wage war," a typical one reads.
