A 17.2 hand bay gelding bred in Ireland, Irish Cap was owned and trained by Bruce Davidson. Irish Cap carried Davidson to a third-place finish at the 1974 Badminton Horse Trials but he is probably best known for sweeping the medals at the 1974 European Championships held at the Burghley Horse Trials in England. Davidson and Irish Cap not only were members of the gold medal team, but they also won the individual gold medal.

Two years later, at the 1976 Olympic Games in Montreal, Irish Cap and Davidson helped the U.S. Team win the Olympic gold medal.
