Invasion of Isle de France

29 November – 3 December 1810, Grand Baie and Port Louis, Mauritius (Île de France)

British victory; the island surrendered with every French warship in its harbours

After Grand Port and the frigate actions off Réunion, Vice-Admiral Albemarle Bertie gathered about 70 ships and nearly 7,000 troops under Major-General John Abercromby. Using surveys of the reefs that ring the island, they chose a landing at Grand Baie in the north, and on 29 November the vanguard went ashore unopposed. The army pushed south on Port Louis (Port Napoléon), crossing the River Tombeau before the militia could destroy the bridge, and on 1 December broke the line of General Decaen's regulars in front of the town. Decaen asked for a ceasefire the next day and surrendered on the 3rd, on terms that sent his garrison home. Six French frigates, a corvette and a brig were taken in the harbours, with 24 merchant ships and 209 heavy guns, and the British prisoners from Grand Port and the captured Indiamen were freed. Mauritius stayed British after the war.
