HMS Ceylon had been despatched by the British authorities at Madras after the Battle of Grand Port to reinforce the remains of the squadron under Commodore Josias Rowley on Île Bourbon.
Searching for Rowley off Île de France, Ceylon was spotted by French Commodore Jacques Hamelin who gave chase in his flagship Vénus, supported by a corvette.
In 1809 and early 1810, these frigates operated with impunity along British trade routes, capturing seven valuable East Indiamen, a number of smaller merchant ships and several small warships.
[3] In August 1810, a squadron of four of Rowley's frigates, making up the majority of the forces under his command and led by Captain Samuel Pym, were despatched to Île de France to blockade Grand Port on the south-eastern coast.
Pym was unable to withdraw his remaining ships and the entire squadron was lost, leaving Rowley with only his flagship HMS Boadicea and two small brigs to conduct his campaign against six large French frigates.
Hamelin, recognising that his vessel had the advantage in size and weight of shot, did not wait for Victor but attacked immediately, passing Ceylon and turning across her bows to open a raking fire.
[11] For an hour the frigates exchanged broadsides, until 01:15 when Hamelin, who had realised that he was fighting a warship not a troopship or East Indiaman, dropped back to effect repairs after suffering damage to his rigging.
[13] As dawn broke and visibility cleared, the sailors on Ceylon, Vénus and Victor realised that they were within sight of Saint Denis on Île Bourbon, and thus vulnerable to counterattack from Rowley's flagship Boadicea.
[15] As soon as the French prize crew was removed, Lieutenant Philip Fitz Gibbon, the remaining officer on Ceylon, rehoisted British colours and assumed control of the ship.
[11] Hamelin recognised that the battered state of his flagship meant that he would not be able to adequately defend against Rowley's attack and ordered Victor to take news of his defeat back to Port Napoleon.
[17] Nearly four decades later the battle was among the actions recognised by the clasps "BOADICEA 18 SEPT. 1810", "OTTER 18 SEPT. 1810" and "STAUNCH 18 SEPT. 1810" attached to the Naval General Service Medal, awarded upon application to all British participants still living in 1847.
The French were no longer able to repair or maintain their ships due a lack of naval stores on Île de France, and so remained in port and prepared for the inevitable invasion.
Bertie was credited with the final defeat of Île de France and was made a baronet as reward for the successful campaign, sending Rowley back to Britain with despatches.
