Frankie Dettori sported the royal colours of the Queen aboard the William Haggas-trained Call To Mind, who was a leading contender for this one-mile-seven-furlong Group Two having impressed in a Goodwood Listed event at the end of August.
The three-year-old raced on the speed throughout and managed to see off Darbuzan in the final furlong, but Pascal Bary's Ice Breeze came through a gap on the rail to get up and score narrowly in the hands of Vincent Cheminaud.
Bary said: "We beat the Queen! He was given a masterful ride, but I think our horse was a little bit better than Dettori's horse.
"I think this horse can be a very good stayer next year. I was quite confident he would run a good race today.
"I think for this year he will be finished now and we will wait for the spring. He will be a nice horse for the Prix Vicomtesse Vigier and maybe the Gold Cup (at Royal Ascot)."
