Antiques Roadshow expert Mark Smith was tasked with valuing a Victoria Cross medal in a classic episode of the BBC show, which will air on Sunday.
As the team returned to Portchester Castle in Hampshire, Mark began: "This is a unique moment on the Antiques Roadshow. In all the years I've been on the roadshow, we have never had a Victoria Cross. The highest award for gallantry this country has. Who was this man?"
"This was my wife's grandfather. Unfortunately, I wasn't privileged enough to meet him but my wife knew him when she was a young child," the guest replied and his wife added: "I have very vague memories because I was only coming up for my fifth birthday when he passed away. I'm very proud of him obviously with what he achieved."
