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.”
