Prince William joined his father, King Charles, for a Remembrance reception at Windsor Castle on Tuesday, marking 107 years since the end of the First World War — a conflict that claimed more than 886,000 British military lives.

Honouring veterans at Windsor Castle

In a video shared on Instagram, the Prince of Wales, 43, could be seen alongside the King meeting veterans of the Second World War during the evening event. Wearing his military medals, William greeted servicemen and women from across the UK and Commonwealth.

“Honoured to be at Windsor Castle this evening to mark 80 years since the end of the Second World War in the Far East with Their Majesties,” the prince captioned the post. “It was deeply moving to meet veterans from across the UK and Commonwealth who served in the Pacific and Indian Ocean territories — a generation whose courage and sacrifice brought peace to millions, and whose legacy continues to inspire us today.”

He ended with a simple tribute: “Lest We Forget.”

Royal followers quickly filled the comment section with messages of gratitude and admiration. “They were young men, very courageous,” one wrote. Another added, “God bless King Charles, Prince William, and all these wonderful veterans.” Many praised the event as “a lovely engagement” that “meant so much to the veterans and their families.”

William’s message to the next generation

Earlier in the day, Prince William appeared in a special video for schoolchildren aged nine to fourteen, encouraging them to wear poppies for Remembrance Day.

“Armistice Day is an important time for us to stop and reflect; it is a reminder that Remembrance is for everyone,” he said. “When we remember, we connect with service in a personal way. We learn from the courage of others, and we carry their stories forward so they are not forgotten. It’s not just about the past — it’s about shaping who we become in the future.”

He added that Remembrance “teaches empathy, resilience, and responsibility,” noting that wearing a red poppy or taking a moment of silence is a way of saying: “Thank you. We have not forgotten, and we will not forget.”

Concluding his message, William said: “Coming together for Remembrance is a vital way to honour those whose service keeps us safe. Even today, as we continue to face conflicts across the world, we honour those who have gone before us and those who are serving now. Their memories matter, their lives matter, and they remind us to be respectful, kind, brave, and thoughtful every day.”
