The firefighter who heard Princess Diana’s final words stated that the memories of that awful night will stay with him forever.

Xavier Gourmelon, 58, was one of the first responders to the tragic sight inside the Pont de l’Alma tunnel in Paris, France, in 1997.

Check out what he had to say here.

It has been nearly three decades since the fatal vehicle tragedy on August 31, 1997, which shook the royal family and the whole globe.

Diana, 36, was temporarily in Paris with Egyptian film producer Dodi Fayed, the son of Harrods owner Mohamed Al-Fayed.

The pair was driving in a black 1994 armored Mercedes-Benz S 280 sedan driven by Henri Paul, the deputy head of security of Al-Fayed’s hotel, the Hôtel Ritz Paris.

They planned to dodge cameras by enabling a fake car to go first and exiting through the hotel’s back door.

Trevor Rees-Jones, a member of the Fayed family’s personal protection squad, sat in the front passenger seat, with Diana and Dodi in the back.

None of the car’s occupants wore a seatbelt.

Eyewitnesses reported that paparazzi swarmed Diana’s vehicle as they passed through the Place de l’Alma underpass.

According to accounts, Paul lost control of his Mercedes at the tunnel’s entrance and collided with a vehicle before crashing into a pillar that held the underpass’s ceiling.

The truck whirled, collided with the tunnel’s stone wall, and eventually came to a stop, killing or critically injuring people within.

Emergency crews pronounced Dodi and Paul dead on the spot while they worked to extract the Princess of Wales from the debris.

That’s when fireman Xavier Gourmelon heard Diana’s dying words, even if he didn’t recognize her at the moment.

On the 20th anniversary of her death, the French native spoke with Good Morning Britain about what she said to him, revealing that his staff had no idea a royal was in the car.

He went on to say that Diana was asleep when he approached, but she abruptly awoke.

Gourmelon remembered, “She looked at me and said, ‘Oh my God, what’s happened?'”

He claimed that the princess appeared ‘agitated,’ so he tried to ‘calm her down,’ but she then passed out again.

When asked what happened after she was pulled from the automobile wreckage, the former firefighter replied, “At that point, the doctor said she was in cardiac arrest.”

“So, we gave her CPR, and after 20 seconds, she regained consciousness, and we transferred her to the ambulance.”

Gourmelon believed Diana would recover fully, but she died from her injuries at the Pitié-Salpêtrière Hospital in Paris.

The 36-year-old experienced another cardiac arrest in the hospital, and physicians were unable to resuscitate her.

Gourmelon told The Sun about his encounter in 2017: “To be honest, I hoped she would survive. But I discovered later that she had died in the hospital. It was quite distressing.

“I now know there were major inside injuries, yet the entire incident remains vivid in my memory.

“And the memories of that night will be with me forever.

“I had no notion that it was Princess Diana. Only after loading her into the ambulance did one of the paramedics inform me that it was Princess Diana.

A French inquiry following the collision blamed Henri Paul, whereas a British inquest found Paul and the paparazzi involved in an illegal homicide due to severely irresponsible driving.
