Gordon Lord Byron came with a late rattle under William Buick to win the Qatar Prix de la Foret for Tom Hogan for Irish success at Longchamp.
Stepped back up to seven furlongs, the distance over which the Irish challenger won the City of York Stakes, the four-year-old looked to have plenty to do a furlong out as David O'Meara's Penitent, also supplemented, made a bold bid for home.
But Gordon Lord Byron picked up well and powered home to give Hogan his first Group One success.
Delzangles made it an afternoon to remember as Molly Malone saw out the gruelling Prix du Cadran best of all.
Jamie Spencer attempted to make all on Vadamar, a stablemate of the winner, and for a brief moment he looked to have slipped the field.
Molly Malone stayed on relentlessly under Umberto Rispoli, though, and ended up winning going away.
The Gold Cup winner Colour Vision was handy throughout but was denied second close home by Graham Lee on James Fanshawe's High Jinx, who looked one of the first beaten before staying on strongly.
Saddler's Rock made some progress from the back but was never on terms.
