Cause

France deployed cruisers from Isle de France and Isle Bonaparte to conduct offensive operations against British merchant shipping in the Indian Ocean during the Napoleonic Wars, targeting valuable East India Company convoys as part of a concerted strategy to disrupt British trade.

Event

On 31 May 1809, the French frigate Caroline intercepted an East India Company convoy of three East Indiamen in the Bay of Bengal. Though the merchant vessels resisted with their own cannon, they were outmatched in firepower, maneuverability, and crew training, and were defeated one by one. Only the smallest ship managed to escape capture.

Consequence

The action marked the opening of a sustained French campaign against British convoys in the Indian Ocean. Subsequent attacks on other important convoys followed, exposing the structural weakness of lightly armed merchant vessels against French naval frigates operating from island bases in the region.
