Five years ago the Chantilly trainer’s Six Perfections suffered a nightmare passage in the race before eventually going down by a rapidly diminishing margin to Russian Rhythm.
There were no such hard luck stories this time as Christophe Lemaire bounced the grey out of the stalls and made a beeline for the stands rail.
Winner of the Cheveley Park Stakes here last autumn, the well-backed 11-4 favourite strode out majestically in front and responded through the closing stages to collect by half a length.
Spacious stayed on to be second, with Saoirse Abu third, Infallible fourth and the unlucky-in-running Nahoodh an agonising fifth.
“She has done something fantastic. They all came to her, but she ran to the end,” said Bary.
“She is a fantastic filly. I have dreamed about this since last October.
“She is very brave and she moves very well, even when she is in front she doesn’t pull or anything like that.”
A winner over five and six furlongs last term, the daughter of Divine Light tackled seven furlongs for the first time when successful in last month’s Prix Imprudence and Bary always thought the mile trip would be in her range.
“I was quite confident she would stay a mile after the Prix Imprudence,” he said.
“We would have preferred to have a couple of horses in front of us, but she has plenty of speed and was able to make the running.
“She is in the Irish Guineas, but with the way she has won today she may need a bit of time.
“She has done all of the work from the front, so I may look to Ascot with her. She has done everything right, so I don’t want to do something wrong. She will tell me when she is ready to race.”
Reflecting on his past experience of the race, he added: “Six Perfections was very unlucky but after that she went on to win the Marois and Breeders’ Cup so we forgot about the Guineas. But this filly is not the same kind as Six Perfections.
“Six Perfections had to wait behind and run a very fast final furlong, but this filly can do it either way and has less chance of being unlucky.”
The charismatic Lemaire is no stranger to success on the Rowley Mile with wins in the Queen Elizabeth II Stakes and Champion Stakes also to his name, but he was elated after securing his first English Classic.
He said: “She has done it beautifully and has given me my first Classic success in England which is very special.
