Dillon guessed that he meant La Perouse, whose disappearance had troubled the whole world. He tried to get on to Vanikoro, where, according to the Lascar, he would find numerous debris of the wreck, but winds and tides prevented him. Dillon returned to Calcutta. There he interested the Asiatic Society and the Indian Company in his discovery. A vessel, to which was given the name of the Recherche, was put at his disposal, and he set out, 23rd January, 1827, accompanied by a French agent. The Recherche, after touching at several points in the Pacific, cast anchor before Vanikoro, 7th July, 1827, in that same harbour of Vanou where the Nautilus was at this time. There it collected numerous relics of the wreck—iron utensils, anchors, pulley-strops, swivel-guns, an 18 lb.-shot, fragments of astronomical instruments, a piece of crown work, and a bronze clock, bearing this inscription—“Bazin m’a fait,” the mark of the foundry of the arsenal at Brest about 1785. There could be no further doubt. Dillon, having made all inquiries, stayed in the unlucky place till October. Then he quitted Vanikoro, and directed his course towards New Zealand; put into Calcutta, 7th April, 1828, and returned to France, where he was warmly welcomed by Charles X. But at the same time, without knowing Dillon’s movements, Dumont d’Urville had already set out to find the scene of the wreck.
