Mauritius campaign (1810–1811) The Mauritius campaign (1810–1811) was a series of naval warfare and amphibious operations during the Napoleonic Wars fought between Royal Navy and British Army forces and the naval and colonial forces of the First French Empire around Île de France (Mauritius) and Bourbon (Réunion). The campaign included cruiser warfare, the decisive Battle of Grand Port, and British invasions that resulted in the capture of both islands, securing British control over the Indian Ocean trade routes and affecting operations related to the British East India Company, Cape Colony, and Madras Presidency.

Background

In the lead-up, French privateering and squadron operations from Île de France (Mauritius) and Bourbon (Réunion) threatened convoys between Britain, the British East India Company, and colonial possessions such as Cape Town, Madras, and Ceylon. The British government, coordinating with the Admiralty, India Office, and commanders at Cape of Good Hope, sought to suppress the threat posed by captains like Guy-Victor Duperré, officers such as Hamelin (comte de la), and shore commanders under governors including Charles Decaen. Previous actions including the Battle of Pulo Aura, cruiser actions by vessels like Bellone (1806), and convoys escorted by squadrons from Rear-Admiral Sir Josias Rowley framed the strategic imperative to seize the islands to protect East Indiaman convoys and secure lines to Australia and China.

Naval operations and engagements

Naval operations combined frigate actions, frigate squadrons, and blockade duties by commanders including Josias Rowley, Samuel Pym, and elements of the Royal Navy against French squadrons under admirals such as Guy-Victor Duperré and captains like Pierre Bouvet. Major engagements included the costly Battle of Grand Port (a French victory against a British squadron), cruiser duels involving frigates such as HMS Africaine, HMS Sirius, HMS Nereide, and French frigates like Bellone and Iphigénie. Blockade efforts were staged from Madras, Cape Town, and St. Helena with support from vessels of the Honourable East India Company and transports supplying troops from Madras Presidency and Cape Colony. Signals, convoy protection, prize captures, and actions at anchorages such as Grand Port and Riviere Noire shaped the operational tempo prior to amphibious assaults.

Invasion of Île Bourbon (Réunion)

The British invasion of Bourbon (Réunion) combined naval bombardment and landings executed by forces drawn from squadrons under Josias Rowley with troops embarked from Madras and Cape Colony transports. Coordinated actions involved marines from frigates such as HMS Boadicea and detachments of British infantry with colonial units to capture key ports including Saint-Denis and Saint-Paul. French colonial commanders attempted resistance using batteries and garrison units under colonial governors reporting to Charles Decaen, but superior British sea control and logistics led to the occupation of Bourbon (Réunion), the seizure of naval stores, and the neutralization of bases used by privateers, enabling subsequent operations against Île de France (Mauritius).

Invasion of Isle de France (Mauritius)

Following the neutralization of Bourbon (Réunion), the British assembled a larger expedition combining elements of the Royal Navy, transports of the Honourable East India Company, and British Army brigades under commanders dispatched from Cape Town and Madras. Amphibious landings were conducted near Grand Port and Port Louis with naval gunfire support from ships including HMS Boadicea, HMS Ceylon, and squadron frigates. After earlier naval setbacks such as the Battle of Grand Port, British commanders adapted tactics, securing beachheads and advancing inland against French forces under local commanders, culminating in the capitulation of Île de France (Mauritius) and the surrender of governor Charles Decaen's administration and remaining French frigates.

Aftermath and consequences

The capture of Bourbon (Réunion) and Île de France (Mauritius) eliminated French privateer threats to East Indiaman convoys, bolstered British dominance in the Indian Ocean, and influenced later operations involving the British East India Company, Cape Colony, and trade routes to China and Australia. The campaign affected diplomatic arrangements such as the broader Napoleonic Wars settlement and contributed to postwar transfers formalized in treaties including provisions at the Congress of Vienna era. Naval lessons from actions like the Battle of Grand Port informed Royal Navy doctrine on frigate operations, blockade enforcement, and amphibious coordination. The islands remained under British control, eventually leading to colonial administrative changes involving colonial governors and incorporation into the British Empire.

Order of battle and forces involved

Order of battle listings include squadrons of the Royal Navy—frigates, sloops, and transports—under Josias Rowley, detachments from the British Army including battalions raised in Madras and units from Cape Colony, and ships of the Honourable East India Company. French forces comprised frigates and corvettes under captains such as Guy-Victor Duperré and squadron leaders including Pierre Bouvet, colonial garrisons under governors appointed by the First French Empire, and privateer contingents drawn from Bourbon (Réunion) and Île de France (Mauritius). Notable vessels engaged were HMS Africaine, HMS Sirius, HMS Nereide, HMS Boadicea, Bellone (1806), and Iphigénie (1805), while supporting logistics involved transports contracted by the Honourable East India Company and supply bases at Cape Town and Madras.
