Members of The Royal Family joined the Belgian Royal Family in Ypres to mark the centenary of Passchendaele - the bloodiest battle of World War I.
While today's Scottish ceremony was taking place, royalty, politicians and relatives were gathering in Ypres for a ceremony at the Menin Gate, which is etched with the names of thousands of missing soldiers.
Prince William attended the event with his wife, the Duchess of Cambridge, as did the British prime minister Theresa May and many other dignitories. "Today, said with gravity, the future king of England in power, the Menin Gate lists the almost 54,000 names of men who had not returned, the missing who have no known grave".
In remembrance of these valiant disappeared, petals of poppies, the famous "poppies" symbolic of the memory of the soldiers fallen on the field of honour in the United Kingdom, fell in rain from the top of the Menin Gate.
Here they heard the Last Post, which has been played at the gate by a bugler nearly every evening since 1928, and the commemorations continue today with a special service held at Tyne Cot cemetery, where thousands of soldiers are buried. Joining them will be 4,000 descendants of those who fought, who won tickets from a government run ballot.
Total Solar Eclipse 2017
Weather permitting, anyone standing within the path of totality will experience the moon entirely blocking out the sun. On the bottom left is Boise, the state capital, which is about 20 miles outside the path of totality.
A service will be held in Ypres, where the King of Belgium and Prince William will lay wreaths at the Menin Gate.
Monday's poignant Last Post was the 30,752nd time it has been played in Ypres since 1928.
The Allied campaign, fought by British and Commonwealth forces from July to November 1917 in mud-caked battlefields, barely moved the front line against the Germans.
About 275,000 Allied troops and 220,000 Germans died.
