The Queen has described for the first time fighting off an attack by a man on a train ‍when she was a teenager, speaking in an interview with the BBC in ​which she recounted how furious the assault had left her.

“When I was a teenager, ⁠I was attacked on a train … I remember at the time being so angry,” she said during a discussion broadcast on Wednesday about violence against women.

“I was reading my book and you know this boy — man — attacked me, and I ‌did fight ​back.”

She said she did not know the man who attacked ‍her.

The Queen, 78, has for many years championed charities and causes that seek to end sexual and domestic violence and to support victims.

The assault was first reported in September when a book about the royal family was serialised in the Times newspaper, but ​had not previously been confirmed by ‌Buckingham Palace.

“I remember getting off the train and my mother looking at me and saying ‘Why is your ​hair standing on end and why is the button missing from your ‍coat?’,” the Queen told the BBC.

“I was so furious about it and it’s sort of lurked for many years.”

The book said the incident happened ​on ​a train to Paddington Station ​in London when the Queen was 16 ​or 17 years old, and she responded by taking off her shoe and using it to hit him in the genitals.

When she arrived at Paddington, she pointed the attacker out to an official and he was arrested, the book said.

The Queen did not confirm those details in the interview.

She is the second wife of ‍the King, who ascended the throne in 2022.
