 Despite winning the Battle of Grand Port, the only French naval victory over the British during these wars, the French could not prevent the British from landing at Cap Malheureux three months later.They formally surrendered the island on the fifth day of the invasion, 3 December 1810, on terms allowing settlers to keep their land and property and to use the French language and law of France in criminal and civil matters.Under British rule, the island's name reverted to Mauritius.
