Princess Anne suffered a bout of memory loss after being struck on the head by a horse in an unfortunate incident.

According to the Daily Mail, the Princess Royal is “unable to recall exactly what happened” that led to her to a hospital on Sunday. 

As per eyewitnesses, she sustained minor injuries and a purported concussion following the incident, which occured while she was walking around her Gatcombe Park estate in Gloucestershire.
