article: It was one of the most horrific disasters of the First World War, which still haunts the descendants of those who died. Yesterday, as commemorations were held all over the world to mark the 100th anniversary of the Gallipoli campaign, the Royal Family led tributes to those who fought and fell in the ill-fated offensive. The day began in London with a dawn ceremony at Wellington Arch on Hyde Park Corner, attended by Princess Anne. Later the Queen, joined by the Duke of Edinburgh, Prince William and political leaders, led the nation during a ceremony at the Cenotaph in Whitehall, while Prince Charles was in Turkey with Prince Harry.

The national flags of Australia, New Zealand, Turkey and the UK were carried through the Abbey and placed close to the high altar as a sign of reconciliation between old enemies. Earlier, Charles and Harry joined more than 10,000 people in a dawn pilgrimage at Gallipoli to honour the bravery of the Allied troops who stormed the peninsula's beaches in 1915. The landings were supposed to be a decisive blow that would knock the Turks out of the war. But eight months of bloody fighting later, after an estimated 145,000 lives on both sides had been lost, the Allies pulled out, having failed in their objective. Around 58,000 Allied troops were killed, many from Australia and New Zealand. Almost 36,000 Commonwealth servicemen are buried or commemorated on Gallipoli. Prince Charles gave a moving reading about troops weeping as they left their dead comrades behind when they left Gallipoli. He read the words of a soldier, who wrote: 'The hardest feature of the evacuation was in leaving those dead comrades behind. They had bequeathed us a sacred trust.'
