The Duke of Edinburgh, who served in the Royal Navy in World War II, was in Ypres, Belgium on November 11, 2013 where, as Colonel of the Grenadier Guards, attended The Last Post Ceremony at the Menin Gate Memorial to the Missing. The Last Post is a bugle call that is played as the final salute to the fallen. This was the latest Remembrance ceremony in the past several days in which the 92 year-old husband of Queen Elizabeth has participated. Ypres is the scene of the some of the deadliest battles held during World War I. Bags of soil had been collected by Belgian students from battlefields in Flanders. The bags of soil were brought to London where they are to be placed at the Flanders Fields Memorial Garden at the Guards Museum in London. Accompanying the Duke of Edinburgh at the ceremony of The Last Post was Prince Laurent of Belgium. The Duke and the Prince each laid a wreath of poppies at the memorial. Photos by Getty Images.
