The Prince of Wales joined the Duke and Duchess of Cambridge for a second day of engagements acknowledging the centenary of the Battle of Passchendaele in Belgium. Today’s event was held at the Tyne Cot cemetery located just outside of Ypres, the largest Commonwealth burial ground in the world. The site contains the graves of 11,971 servicemen and is an important stop in remembering Passchendaele given the sheer volume of casualties from the summer of 1917.
