Planning The initial landing mission was organised in secrecy by a group of five people: the four British Chagossians
Misley Mandarin, his father Michel Mandarin, Antoine LeMettre, and Guy Castel, and former British MP
Adam Holloway. Michel was born in the islands and was 14 when he was expelled in the
expulsion of the Chagossians, the déraciné, or uprooting, and put on to boats by the British colonial authorities. Michel said there are 322 people who were born in the islands and still living that wish to return home before they die, in addition to a far larger number of descendants born elsewhere post-expulsion. The group received funding from British-Thai billionaire
Christopher Harborne, and bought a boat in
Thailand. The boat was then loaded with provisions in
Galle,
Sri Lanka, from where the group embarked on a five-day sail to Île du Coin, entering the exclusion zone of the
British Indian Ocean Territory unannounced without seeking permission.
Arrival The landing party set foot on Île du Coin on Monday 16 February 2026 at 08.52 local time (02.52 GMT), with the four Chagossians staying there to reestablish a permanent settlement. The news of the mission only became public following the landing. Mandarin sought to reassure the United States that the settlement did not threaten the military base on
Diego Garcia. On 18 February 2026, they were served a removal order in the name of
Royal Marines Major Pete Goddard, as Acting Principal Immigration Officer of the
British Indian Ocean Territory, stating that if they did not leave they could face imprisonment of three years or a fine of £3,000, or both. On 19 February 2026, the Chagossians' lawyer, James Tumbridge, successfully applied for an injunction, which was granted by Chief Justice of the British Indian Ocean Territory,
James Lewis, who stated "there is no doubt the balance of convenience falls on the side of the claimants (the islanders). They are 120 miles from
Diego Garcia and pose no threat to national security on the evidence before me". On 26 February two more Chagossians arrived on the islands, Clifford Aglae and Andy Antanika, bringing the islands' population up to six. ==Legal status==
