The Queen paused to reflect as she honoured fallen troops' memories at the official opening of a garden to commemorate some of the First World War's deadliest battles.
She was joined by her husband, the Duke of Edinburgh, and her grandson, the Duke of Cambridge, at the dedication of the Flanders Fields Memorial Garden at Wellington Barracks in central London.
