For the next two years, the British raided ports and anchorages on the French islands while the French attacked trade convoys in the wider ocean.

 under Keating and Willoughby landed on Île Bonaparte and marched around the town's seaward fortifications, storming them from the rear at first light. Capturing each in succession and routing opposition from French militia, the force secured the gun batteries overlooking the port, allowing Rowley to bring his squadron directly into the harbour and bombard the shipping anchored within. The French naval officers, outnumbered and unsupported, drove their ships on shore and abandoned them, allowing the British to seize and carry off Caroline, the two captured East Indiamen and a number of smaller vessels. French attempts to recapture the town were undermined by the failure of the island's commander, General Nicolas Des Bruslys, to engage the British with his main force. Des Bruslys later committed suicide. With the garrison leaderless, a truce was agreed that granted the British five days in control of the town. In this time they were able to remove all government supplies and demolish the town's government buildings. Rowley and his force eventually departed from Saint-Paul on 28 September. As a reward for their services, Willoughby was promoted to command Nereide and Corbet sent back to Britain in Caroline, renamed HMS Bourbonaise.

With their crews now dispersed among their prizes and cyclone season rapidly approaching, Hamelin ordered his squadron back to Ile de France. En route, the convoy was struck by a storm and scattered: Vénus was especially badly damaged and at one point was only saved from sinking by the efforts of the English prisoners aboard. By 31 December, all ships had returned to Île de France except Windham, which had been recaptured by the recently arrived British frigate HMS Magicienne.

Invasion of Île Bonaparte

Although the French Navy considered 1809 to have been a success, they reinforced Hamelin with only one frigate, the Astrée, which arrived early in 1810. Hamelin was quick to act at the end of the cyclone season: Captain Guy-Victor Duperré

 and HMS Leopard arrived off Île de France to restore the blockade. Rowley subsequently increased Lambert's forces, detaching Willoughby in Nereide with instructions to raid coastal anchorages on the island. On 24 April, Willoughby sighted the recently arrived Astrée, and on 30 April attacked the protected anchorage at Jacolet. His target was a large French merchant ship protected by two batteries and a detachment of regular infantry. Landing at night under heavy fire, Willoughby's men seized one battery, drove off a French attack on their beachhead and captured the second battery despite having to advance across a river, under fire, in broad daylight. On returning to their boats, Willoughby's men were attacked by a second French force which they also routed and drove more than a mile inland. Shortly afterwards however, Willoughby was seriously wounded when a musket

 he was firing exploded, shattering his jaw. As a result, he was forced to spend several months recovering from his injuries on Rodriguez.

During the late spring, Rowley's force was shorn of Raisonnable and Leopard, sent back to Britain for refit. Although reduced to five frigates and a few smaller vessels, Rowley began preparations for the invasion of Île Bonaparte

 by increasing the number of soldiers available on Rodriguez with detachments sent from Madras. Bonaparte was the smaller of the French bases and was more weakly defended, the island's defences damaged in the raid at Saint Paul the previous year. On 24 June, Rowley withdrew Boadicea and Nereide to Rodriguez and collected Keating's force of over 3,000 soldiers. Meeting the rest of his squadron off Bonaparte, Rowley organised two landings on 7 July, either side of the island's capital Saint Denis. Advancing rapidly against weak French defences, the British landing parties forced the island's governor Chrysostôme de Sainte-Suzanne to surrender the following day. It was in the days after this operation that Commander Matthew Flinders

, an explorer who had been arrested by Decaen at Port Napoleon eight years earlier and held prisoner despite instructions from Napoleon himself to release him, was freed. Flinders was able to supply Rowley and later Bertie with detailed information about the defences on Île de France.

Battle of Grand Port

Even before the French garrison on Île Bonaparte had surrendered, Rowley had turned his attention eastwards to Île de France. The British commander had decided that the best way to eliminate the threat of Hamelin's squadron was to blockade the island's principal ports by seizing the coral islands that marked the entrances to the harbours through the complicated coral reefs that surrounded Île de France. These islands were fortified, and once in British hands could prevent French ships leaving or entering the harbours, effectively containing Hamelin's ships until Rowley was ready to launch an invasion. Detailed to lead this campaign was Captain Samuel Pym

 in Iphigenia and Lucius Curtis in Magicienne, blockaded Port Napoleon. On 20 August, sails were spotted approaching Grand Port and Willoughby determined to trick the approaching ships into entering the channel under Île de la Passe, where he could attack and capture them. The squadron was Duperré's squadron returning from the African coast with their prizes and, despite misgivings from Captain Bouvet, Duperré was determined to enter Grand Port and reassured by recognition signals flown by Willoughby, who had captured the French codes on Île de la Passe. As the French passed the fort, Willoughby sprang his trap and opened fire, but a false French tricolour flying from Île de la Passe accidentally ignited as it was lowered. The fire spread to a ready magazine in the fort, which exploded, causing severe damage and casualties. In the confusion all but one of Duperré's ships successfully entered the harbour.
Willoughby appealed to Pym for assistance and Pym brought Sirius, Iphigenia and Magicienne to support Nereide, launching an assault on Grand Port on 23 August. Pym had failed to properly reconnoitre the channel and Duperré had had the warning buoys removed, so that Pym's squadron was blindly sailing into a complicated system of reefs and channels. Sirius and Magicienne were soon irretrievably grounded while Iphigenia struggled to find a passage and was unable to close with the French squadron. Only Nereide reached Duperré's line and Willoughby's initial attack was so determined that the entire French squadron was rapidly driven ashore, only Bellone remaining in a position to exchange fire with the British frigate. A fortunate shot from Bellone cut Nereide's anchor cable and the British frigate swung around, presenting her stern to the French ships which raked

In naval warfare, raking fire is fire directed parallel to the long axis of an enemy ship. Although each shot is directed against a smaller target profile than by shooting broadside and thus more likely to miss the target ship to one side or the other, an individual cannon shot that hits will pass...

 her repeatedly. Willoughby managed to mitigate some of the effects by cutting the other anchor cable, which brought some of his guns within range of the French, but the balance of the battle had shifted. Over the next few hours his frigate was battered from the French ships and from guns ashore until she was a dismasted, battered hulk with over 220 of her crew killed or wounded.

Nereide surrendered on the morning of 24 August and over the next three days Magicienne and Sirius were abandoned and burnt to prevent their seizure by the French. On the morning of 28 August, Iphigenia, laden with survivors from the grounded frigates, was confronted by Hamelin and his main squadron, which had taken seven days to travel from Port Napoleon. Hugely outnumbered, Lambert had no choice but to surrender, ending the worst British naval defeat of the entire war. Rowley arrived in Boadicea on 29 August but was unable to influence the outcome of the battle and was chased back to Saint Denis by Hamelin on Vénus. On the defensive, Rowley sent messages to Rodriguez, Madras and the Cape of Good Hope requesting urgent reinforcements as Bouvet began a blockade of Île Bourbon in the hope of trapping Boadicea.

On 11 September the frigate HMS Africaine arrived from Rodriguez, commanded by Captain Robert Corbet who had served in the raid on Saint Paul in 1809. Corbet was a deeply unpopular commander and when his frigate was attacked and captured by Bouvet's frigates at the Action of 13 September 1810

 was captured by Hamelin's flagship Vénus. Again, Rowley was able to recapture the British frigate and on this occasion the damage done to Vénus was so severe that she was unable to outrun Boadicea and she too was captured, with Hamelin on board.

Capture of Île de France

In September, October and November 1810, British forces arrived from Madras, Bombay and the Cape of Good Hope, warships joining Rowley's squadron off Île de France and soldiers gathering at Rodriguez. The build up of forces was prompted by the defeat at Grand Port combined with the heavy losses of East Indiamen during 1809 and 1810; the British authorities were determined to end the threat posed by the French squadron on Île de France before the hurricane season made travel in the region too dangerous. In fact, the threat from Île de France was already substantially reduced: the damage suffered by the French frigates in the engagements at Grand Port and during September could not be repaired with the available naval supplies on Île de France. In addition, food supplies were running low due to the large number of British prisoners on the island and morale had collapsed in the aftermath of Hamelin's defeat.

By late November 1810, the invasion force was assembled and Vice-Admiral Albemarle Bertie assumed command at Rodriguez. Upon consultation with his commanders, Bertie decided to land at Grand Baie

. These forces would advance on Port Napoleon with subsequent reinforcement by the main force under General John Abercromby over the following days. This force, nearly 7,000 in number, was significantly larger than the reliable troops available to Decaen, which numbered approximately 1,300, and were intended to achieve a quick resolution to the campaign before the hurricane season began in December.

Sailing from Rodriguez on 22 November, the 70 vessels of the invasion fleet reached Grand Baie on 29 November. The French made no attempt to resist the landing either at sea or on land and Keating was able to rapidly advance on the capital, hastily mobilised militia units falling back before the British advance. On 30 November, Keating crossed the Rivière du Tombeau

 made a stand, forming a line on a rise outside the town that blocked Keating's advance. Engaging the centre, Keating used his superior numbers to outflank and defeat the French garrison and Port Napoleon fell. A ceasefire was agreed on 2 December and the following day Decaen surrendered, although he and his men were repatriated to France with their standards and personal weapons.

End of the campaign

The fall of Île de France marked the end of the active British campaign and saw six frigates and over 200 cannon fall into British hands, in addition to the island itself, which was returned to its original Dutch name of Mauritius and remained under British control until granted independence in 1968. The British forces in the region were scaled back, command passing to Beaver, who sent ships to eliminate French ports on Madagascar

. Due to the length of time it took for communications to travel between the Indian Ocean and Europe however, the French government were still unaware of the fall of the island in February 1811, when a squadron of reinforcements under François Roquebert, with the supplies needed to repair Hamelin's squadron, was despatched to the Indian Ocean. The squadron arrived on 6 May and was almost brought to battle by a British force off Grand Port, before escaping into the western Indian Ocean. Stopping at Tamatave on Madagascar, the French squadron was caught by a British force under Captain Charles Marsh Schomberg

 was characterised by very light winds, which left the combatants becalmed for much of the day, engaging in periodic fighting as the breeze increased.

Two French frigates were lost at Tamatave, taking the number of frigates lost by the French Navy during the campaign to ten. The defeat marked the end of the campaign and the end of French hopes of seriously disrupting British trade with India: the only remaining safe harbours in the region were a few Dutch colonies on Java, which became the next target of the Royal Navy forces in the region. The Mauritius campaign also had an effect on British post-war strategy in the Indian Ocean, demonstrated by the retention of Mauritius as a colony (although Bourbon was returned to France in 1814 after Napoleon's abdication). With strategic bases placed along their trade routes, British convoys were assured a greater degree of safety and the Royal Navy provided with the infrastructure to operate worldwide.
