Britain's Prince William and Prime Minister Theresa May took part in commemorations today marking the centenary of the Battle of Amiens, which heralded the beginning of the end of World War I. The descendants of soldiers who took part in the Allied push, which smashed German defences and morale, travelled from across the world to Amiens for the ceremony in the city's magnificent medieval gothic cathedral.

Senior officials from Britain and France were joined by representatives from the Australian, Canadian and US governments in honour of the tens of thousands of troops killed in the four days of fighting. Former German president Joachim Gauck and Scottish leader Nicola Sturgeon also attended. The Battle of Amiens sounded the start of the Hundred Days Offensive on the Western Front, which led to the Armistice in November 1918.
