On June 8, an exploration and research vessel of the British navy, HMS Blossom (captained by Frederick W. Beechey), arrived at the uninhabited Islands. They discovered Futami harbor on June 9, where he made landfall and explored the island.
 
There the crew were most surprised to find two European settlers.
 
Beechey named Futami harbor where he had anchored Port Lloyd, giving Chichijima the name Peel Island, Hahajima the name Bailey Island, as well as naming the Mukojima Islands as the Parry Group. He also erected a bronze plaque claiming formal possession of the islands for King George IV of Great Britain. (Ref. 1)
