This year’s Festival of Remembrance marks the first month of Remembrance Day events since the Sept. 8 death of Queen Elizabeth. Last year, the late monarch was unable to attend the Remembrance Sunday service at the Cenotaph war memorial due to a sprained back. She rarely missed the annual event, which she considered one of the most sacred in her calendar, only having missed a handful throughout her 70-year reign, such as during times when she was pregnant or out of the country on a royal tour.
