With favourite Radiator failing to find much for pressure once James Doyle asked her to quicken up and get after early leader Sleepy Sioux, it was left to Miss France and Lightning Thunder to fight out the finish to the Group Three contest.
Lightining Thunder stuck on bravely despite drifting left throughout the final furlong and a half, but when the pair came together a few strides before the winning post it appeared more the fault of the winner than the runner-up.
However after a brief stewards' enquiry, the results were left to remain unchanged.
An impressed Barzalona said: "She is a top-class filly. She's a great filly and does everything easily.
"She has won already over a mile so that trip won't be an issue. It was good ground today but I don't think soft ground will be a problem. Can she be a Classic filly? I hope so."
Anthony Stroud, representing owners Ballymore Thoroughbred Ltd, said: "She came here as we thought she would be suited by the stronger pace and better ground. I think they will be thinking the Guineas. It's up to Diane [Wildenstein] and Andre. I'm sure Andre will tell us where we are going. She's got a lot of talent and is an extremely nice filly."
In victory, Miss France gained a quote of 16/1 for next year's 1000 Guineas from Sky Bet.
Spokesman Michael Shinners said: "She was very impressive in the way that she travelled and could be a serious player in next year's 1000 Guineas."
Olly Stevens wasn't too disheartened with the defeat of his previously unbeaten runner-up.
He said: "I'm disappointed but not overly so - she's still a good filly. We will consider the Rockfel and she is in the (Prix Jean-Luc) Lagerdere.
"We are not worried about racing her against the colts - she beat them in a conditions race. I'd quite happily put her away for the winter as well."
