Bartaba showed plenty of fortitude to win the Group Three Prix Belle de Nuit at Saint-Cloud.
Eleven fillies and mares took part in this 1 ¾ mile contest.
Klassique led and took the field into the home straight, where she was challenged by Bartaba.
In a real slog, the two three year-olds pulled clear and whilst Klassique fought back, Bartaba had her measure at the line, with a gap back to Against Rules in third.
The Andre Fabre trained Bartaba, is a daughter of Japanese superstar Deep Impact.
