ロワイヤルオーク賞
Prince Royal was then sent to race in France. He ran in the Prix Royal-Oak in poor racing condition and was held back, finishing last to Baron Guy de Rothschild's winning colt, Barbieri. Negotiations, which had been going on prior to the Prix Royal-Oak, saw American Rex Ellsworth purchase Prince Royal for a reported US$400,000 who turned him over to French trainer, Georges Bridgland. For his new owner and trainer, Prince Royal was next entered in the October 4th running of the Prix de l'Arc de Triomphe. Up against older horses, the three-year-old colt won the forty-third running of France's most important race.
