The Duke of York’s peaceful ride quickly turned wild when his horse grew agitated. The mare thrashed about and reared its head, throwing King Charles’ younger brother off balance as he struggled to hold onto his reins and avoid a fall.

On Nov. 18, the Duke of York, 64, was photographed riding in Windsor, where his horse seemingly got spooked. The dramatic photos show the black horse throwing up its head and Prince Andrew pulling back on the reins while up in the stirrups, reacting to get the animal under control.

Prince Andrew nearly fell off his horse amid the Duke of York's bitter feud over Royal Lodge. During a Monday morning ride through the Windsor Estate, the Duke of York's black mare began showing signs of distress.
