At this point in the race, with some of the horses having passed her, she ducked under the guard rail and ran onto the course. She reached up to the reins of Anmer—King George V's horse, ridden by Herbert Jones—and was hit by the animal, which would have been travelling at around per hour, four seconds after stepping onto the course. Anmer fell in the collision and partly rolled over his jockey, who had his foot momentarily caught in the

Because horses can be ridden and controlled without bits by using a noseband or a hackamore, and such tools are used even today, the absence of bit wear on horse teeth is not conclusive evidence against domestication, but such materials do not produce significant physiological changes nor are they apt to be preserved
