30 years ago today the Blues and Royals were on their way to carry out the guard change on Horseguards Parade. They didn't get there, the IRA detonated a car bomb, 4 men and 7 horses were killed, more injured. This is a photos of Sefton and Echo. Sefton was a cavalry black who had nails stuck in him and Echo was a Metropolitan Police Horse who had a piece of metal embeded in his side. Both retired to the Horse Trust. There was another horse, Yeti who retired with them but no photos of him.
