Treve (144-10) bounced back to her brilliant best to successfully defend her crown in the Qatar Prix de l'Arc de Triomphe at Longchamp. She was retired immediately after the race.
Criquette Head-Maarek's filly was a stunning winner of Europe's premier middle-distance contest 12 months ago, but had endured a largely forgettable four-year-old campaign prior to her return to Paris.
However, with Thierry Jarnet in the saddle once again, Treve looked much more like her old self, travelling powerfully into the straight towards the far rail.
The field were spread right across the track, but once Jarnet pushed the button as the gap came, Treve showed her stunning acceleration to seal a fantastic victory, becoming the first horse since Alleged in 1977 and 1978 to win back-to-back Arcs.
Andre Fabre's Flintshire (20-1) was best of the rest in second, ahead of Oaks and King George heroine Taghrooda (11-2 F) and St Leger winner Kingston Hill.
John Gosden's Taghrooda and the Roger Varian-trained Kingston Hill both emerged with plenty of credit having been drawn very wide.
Aidan O'Brien's trio Tapestry (13th), Chicquita (15th) and Ruler Of The World (ninth) all failed to place.
Harry Herbert, racing advisor to Sheikh Joaan's Al Shaqab operation, revealed Treve would now be retired.
He said: "Her work earlier this week gave Criquette confidence that she might just do this, but to do it how she's done it against a top-class field, to spreadeagle them two years running - it's absolutely phenomenal.
"It's one of the great training performances. We all know it's not easy to bring a filly back in her four-year-old year and to have the knocks along the way, there's been issues along the way.
"And for Qatar - she carries the flag of a nation with her. It was a remarkable performance, a brilliant ride and we don't see animals like this very often.
"She'll be retired now, for sure. She has nothing more to prove.
"She's proved to a few doubters that she is back and as brilliant as ever.
"I think now it's off to the Sheikh's stud farm in Normandy and deciding who will be the lucky husband, or husband number one!
"To be involved with something like this is fantastic, especially as she has come back from adversity. I don't think we can quite believe what we have just seen."
