Apparently she cannot remember the incident

Princess Anne is considered a highly experienced rider – a few days ago she was injured in a horse accident
Is Princess Anne (73) in worse shape than expected? The sister of King Charles (75) is said to have been hit on the head by a horse’s hoof on Sunday evening at her country estate Gatcombe Park and was taken to hospital. Diagnosis: concussion.
But now it comes out: The princess is in a trauma center in Bristol, is being cared for by specialists and has to cancel upcoming appointments.
How bad is Anne really?

Horse lover Anne visited the Royal Ascot, the traditional British horse race, on June 18. The princess is a professional in the saddle herself and took part in eventing at the 1976 Olympic Games
How the accident happened is unclear, as the princess does not remember it. What is certain is that she was walking through her estate in Gatcombe Park in Gloucestershire while her horses were nearby.
Anne’s medical team suspects that her injuries could have been caused by “potential impact” from “headbutts or kicks” from one or more animals.

Princess Anne is being treated at Southmead Hospital in Bristol. The clinic specialises in trauma patients. The palace said Anne is “expected to make a full and speedy recovery”
A rescue helicopter rushed to the scene and treated Anne on site before she was taken to Southmead Hospital , 45 minutes away, accompanied by her husband Sir Timothy Laurence (69) . According to Buckingham Palace, she suffered “minor injuries” and “concussion”. But the special clinic where the princess is being treated shows how seriously the incident is being taken
Is Anne suffering from trauma?
The top trauma center’s homepage explains: “A traumatic event happens unexpectedly. Due to the suddenness, a series of unusual emotional and physical reactions can occur.
The incident will have thrown the resolute princess off course, but in Bristol she is now in the best hands with experienced therapists.

Anne with brother Charles after his coronation in May 2023. According to the palace, the king will be “kept informed” of Anne’s health status while she remains in the clinic “as a precautionary measure”
Appointments cancelled
While the princess recovers, her engagements will have to wait. A palace spokesman confirmed that Charles’ sister is cancelling her appointments for next week. She had nine engagements scheduled in seven days!
Anne actually wanted to attend the state banquet for the Japanese imperial couple on Tuesday. On Thursday she would have flown to Canada for eight appointments.

Gatcombe Park is Princess Anne’s country estate. Here she took a walk through the spacious park on Sunday evening. Husband Timothy Laurence and daughter Zara Tindall were also there. It is still unclear whether the princess was accompanied when the accident happened
Following the cancer diagnoses of King Charles and Princess Kate (42), another royal must slow down, at least temporarily.
Being slowed down like this is bound to be a thorn in the side of dutiful Anne. But after the diagnoses from her relatives, she knows that her health is now a priority.
