Although a number of men were drowned in the heavy surf, the majority of the invasion force reached the beaches safely and marched inland, attacking French outposts as they approached the capital. Recognising that his demoralised garrison would be unable to defend Saint Denis and that the militia would take too long to mobilise, the French commander Colonel Chrysostôme de Sainte-Suzanne surrendered the island, its garrison and its stores to Rowley.

Rowley's ships had some successes: one of the East Indiamen captured by Hamelin was retaken by a blockading frigate in December 1809, but he was largely powerless to prevent the large French ships leaving their fortified anchorages at will.

 of the landing party were able to storm the defences from the landward side and rout the defenders. This allowed Rowley's squadron to enter the harbour and capture Caroline and a number of smaller ships that were docked there. The attack caused consternation on the island and its commander, Nicolas Des Bruslys, committed suicide rather than order his troops to attack the British positions. Unopposed, Rowley was able to destroy the defences and public works in the town before leaving with large quantities of captured supplies and ships. Colonel Chrysostome Sainte-Suzanne replaced Des Bruslys but was unable to effectively defend the island with the remaining garrison in the event of a concerted invasion.

Preparation

 conferred on the best method of invading and rapidly subduing the island, determining that the best plan was to land soldiers either side of the island's capital Saint Denis and defeat the garrison outside the town, forcing the new governor to surrender.

The government in Madras had augmented the garrison of Rodriguez over the previous year, so that by June 1810 it stood at over 3,650 men: 1,800 British Army regulars and 1,850 HEIC Army sepoys under Keating's overall command. To transport these troops, Rowley called up his own frigate HMS Boadicea

Invasion

Rowley's squadron and a number of supporting transport ships reached Île Bonaparte on 7 July. The main body, under Rowley, approached Sainte-Marie

s and the supplies needed for the campaign was landed without loss under the direction of Navy Lieutenant John Wyatt Watling, who had landed first and secured the beach with a party of seamen, distributing the soldiers and supplies as they came ashore. Advancing rapidly to seize the heights over the beach, Frazier drove off French outposts and snipers and cut the main road between Saint Denis and Saint Paul, hampering French communications and the movement of reinforcements.

To the east, on the other side of Saint Denis, Rowley ordered his forces to land. The first ashore was intended to be Nesbit Willoughby in a schooner

 named Estafette, to secure the beach and organise the landing forces. However as this boat approached the beach the wind strengthened and built up a powerful surf, which smashed the schooner ashore with enough force to break it apart: four of the 150-strong landing party were drowned. Realising that the smaller transports would be similarly overwhelmed by the waves, Keating ordered a small brig named Ulney driven on shore as a breakwater

. This allowed a number of additional boats to safely reach the beach but did not provide enough cover for a full landing before nightfall.

By the morning of 8 July, the French had still failed to concentrate their forces, which consisted of 576 regular French Army

 soldiers and 2,717 militia dispersed across the island. Seeing that a landing on the beach at Grande Chaloupe was still practical, Captains Rowley and Lambert successfully landed their contingents, providing Keating with sufficient force to march on Saint Denis. While Keating was landing, Frazier had advanced on the capital from the west, storming a French barricade on the road from Saint Paul and routing its defenders with minimal casualties. Brushing aside French resistance in a series of minor skirmishes, Keating and Frazier's forces closed on Saint Denis. The advancing British were met at 18:00 by representatives of Sainte-Suzanne, who later signed a capitulation that surrendered the entire island to Rowley, Keating and Farquhar with its garrison and supplies.

Offshore, Sirius had blockaded Saint Paul after landing her soldiers and, on 9 July, observed a ship attempting to break out of the harbour after hearing news of the surrender. The Sirius's barge was sent to pursue the fugitive, under the command of Lieutenant George Norman. In an exhausting twelve hour chase, Norman was able to catch and board the ship, revealed to be a privateer named Edward carrying four guns and 30 men. Norman was able to defeat the crew in a brief struggle in which three men were wounded, and discovered that she was carrying despatches from the French government for the authorities on Île de France, all of which fell into British hands.

Aftermath

The invasion cost the British a combined total of 22 dead and 79 wounded, including those drowned in the wreck of Estafette. Most of the other casualties had been incurred in the skirmishes on the road to Saint Denis and French casualties, although not known, were probably of a similar number. The French failed to put up a meaningful resistance to the British force, which rapidly established beachheads and carried French outposts without facing significant opposition. The island reverted to its pre-Revolutionary

 name of Bourbon following the invasion, and Farquhar briefly assumed the governorship before moving to Mauritius upon that island's capture in December 1810. Keating replaced him in command and remained in the position until 1814, when the island was restored to France at the end of the Napoleonic Wars.

The success allowed British forces to concentrate against the one remaining French territory in the Indian Ocean, Île de France. Bourbon provided a number of secure anchorages and plentiful supplies for the British frigate squadron, becoming Rowley and Keating's new headquarters. With a safe harbour only a short journey away, Rowley was able to despatch his frigates against French ports on Île de France more frequently and more aggressively, developing a plan to seize small offshore islands near the main harbours on Île de France to disrupt the passage of shipping and the ability of French frigates to use these ports as raiding bases. This plan ultimately led to the disastrous attempt
