The animals were among a group of four horses that broke free during routine exercises Wednesday near Buckingham Palace, throwing their riders and causing chaos as they galloped loose through central streets during the morning rush hour. A fifth horse that tried to bolt was not able to break free.

The loose horses from the Household Cavalry, the ceremonial guard of the monarch and a feature of state functions in London, were named as Vida, Trojan, Quaker and Tennyson. Cartlidge identified Vida as the white horse seen drenched in blood as it ran at speed down Aldwych, in between London’s historic financial center and the busy West End theater district more than 5 miles from where it bolted. Vida ran alongside a black horse named Quaker that could be seen bumping into a taxi as it turned into oncoming traffic after running through a red light at an intersection. were all captured shortly after and were taken back to barracks in Hyde Park. Cartlidge said the army trains with about 150 horses every day, so the incident was exceptionally rare. “Unfortunately we have seen what has happened, but all I can say is the crucial thing … no serious injuries to the public as far as we aware, and of course we will be keeping an eye on the situation,” he told LBC.
