Reading the evidence

Separate the findings of the investigations and inquest from later allegations. A disputed witness detail is not itself proof of an organised plot, and the treatment of the crash should acknowledge the other people who died or were injured.

History and reconstruction

This account uses reconstructed scenes, atmosphere, and private thoughts. These passages are storytelling, not eyewitness testimony. Dialogue without a traceable source should be read as reconstruction, not as a verbatim historical quotation. The further reading in the EPUB provides context; it is not a citation for every sentence.

Illustrated cover of The Thirteenth Pillar
Date Aug 31, 1997
Verdict Unlawful Killing
Investigations 3
INVESTIGATE

Shortly after midnight on August 31, 1997, a Mercedes carrying Diana, Dodi Fayed, Henri Paul and Trevor Rees-Jones crashed in the Alma underpass in Paris. Paul and Dodi died at the scene; Diana died in hospital. Rees-Jones survived with serious injuries.

The investigations reconstructed the journey, tested claims of a plot and examined responsibility for the deaths. In 2008, a British jury found unlawful killing through grossly negligent driving. It did not find an assassination.

The Crash

12:23 AM

The Mercedes S280 struck the thirteenth pillar of the Pont de l'Alma tunnel at over 60 mph — more than double the speed limit. Three of the four occupants were killed.

Blood Alcohol

1.87 g/L

One test recorded 1.87 grams of alcohol per litre of blood, more than three times the French driving limit. Operation Paget reviewed the toxicology and the identification of the samples.

The Inquest

250

Approximately 250 witnesses gave evidence during the British inquests, which ran from October 2007 to April 2008.

The Funeral

6 Sep 1997

Diana’s funeral at Westminster Abbey on September 6, 1997, was broadcast internationally. Crowds also gathered along the procession route and at outdoor screens in London.

The Evidence

Pont de l'Alma tunnel, Paris
PONT DE L'ALMA TUNNEL

The Thirteenth Pillar

Physical traces indicated contact with a white Fiat Uno before the Mercedes struck the pillar. Operation Paget estimated impact speed at about 65 mph. The Fiat was never conclusively identified.

A Nation in Mourning

Flowers, cards and candles accumulated outside Kensington Palace and other royal residences. The tributes made public grief visible in the days before the funeral.

FLAME OF LIBERTY

The Unofficial Memorial

The Flame of Liberty, a gold replica of the Statue of Liberty's torch, stands above the crash tunnel. It predates Diana's death but became a public shrine. The site was officially renamed Place Diana in 2019.

The Final Night

4:35 PM

Arrival at the Ritz

Diana and Dodi visit the Ritz during the afternoon. Later, while travelling to a restaurant, they change plans and return to the hotel, where they dine in the Imperial Suite.

10:08 PM

Henri Paul Returns

Henri Paul returns to the Ritz after being called back. His outward composure on hotel footage would later be compared with the toxicology evidence of impairment.

12:20 AM

The Decoy Plan

Diana and Dodi leave through the Rue Cambon exit in a Mercedes driven by Henri Paul. Trevor Rees-Jones accompanies them, without a following security car.

12:23 AM

Impact

The Mercedes crashes into the thirteenth pillar. Physical evidence indicates prior contact with a white Fiat Uno. Paul and Dodi die at the scene.

4:00 AM

Diana Pronounced Dead

After nearly two hours of emergency surgery at the Pitie-Salpetriere Hospital, Diana is pronounced dead. A torn pulmonary vein had caused massive internal haemorrhage.

APR 2008

The Verdict

The jury finds unlawful killing through grossly negligent driving by Henri Paul and the drivers of following vehicles. The absence of seatbelts and impact with the pillar also contributed to the deaths.
