Following the collapse of the French Indian Ocean squadron in 1799, Britain dominated East Indies sea lanes. To disrupt British ships supplying a Royal Navy squadron in the Red Sea—which was pressuring French forces in Egypt—Napoleon dispatched the frigate Chiffonne under Captain Pierre Guiyesse to operate from the French colony of Mahé in the Seychelles.
On 19 August 1801, British Captain Charles Adam carefully navigated HMS Sibylle through the coral reefs protecting Mahé harbour, where Chiffonne lay undergoing repairs. He brought his frigate alongside and fought a brief but intense engagement, forcing Guiyesse to surrender. The French ship, despite the protection of a hastily built shore battery, could not resist the assault.
With Chiffonne captured and the brig Flèche subsequently intercepted and sunk by HMS Victor, France's attempt to menace British Red Sea operations was completely neutralised. These engagements were the final significant naval actions in the Indian Ocean theatre of the French Revolutionary Wars, and the Peace of Amiens took effect in October 1801, ending the conflict.
