 Caroline was a " tolerably fine frigate " and her capture was a blow to the French squadron based on Île de France under Hamelin . The recapture of the East Indiamen was also an important success , reducing the impact of French operations in the region during 1809 . The raid also provided the British forces with vital experience in conducting amphibious landings staged from Rodriguez and gave an indication of the quality of French shore defences and defensive formations throughout the islands , which would have an important effect on future operations , especially the Invasion of Île Bonaparte in 1810 .
