In 1809, under Captain Mequet, she departed Lorient, France with Troude's squadron, bound for the Caribbean.

On 29 May, Polonais and Courageux reached Cherbourg, France along with seven prize ships captured on the way.

In April 1814, at the Bourbon Restoration, Polonais was renamed Lys captained by Troude.

She was briefly renamed Polonais during the Hundred Days of Napoleon, and then back to Lys again.

After the Bourbon Restoration, Lys was sent to retake possession of the island of Martinique, along with the frigate Érigone and the corvette Vésuve.
