La Perouse, and his second, Captain de Langle, were sent by Louis XVI, in 1785, on a voyage of circumnavigation. They embarked in the corvettes Boussole and the Astrolabe, neither of which were again heard of. In 1791, the French Government, justly uneasy as to the fate of these two sloops, manned two large merchantmen, the Recherche and the Esperance, which left Brest the 28th of September under the command of Bruni d’Entrecasteaux. Two months after, they learned from Bowen, commander of the Albemarle, that the debris of shipwrecked vessels had been seen on the coasts of New Georgia. But D’Entrecasteaux, ignoring this communication—rather uncertain, besides—directed his course towards the Admiralty Islands, mentioned in a report of Captain Hunter’s as being the place where La Perouse was wrecked. They sought in vain. The Esperance and the Recherche passed before Vanikoro without stopping there, and, in fact, this voyage was most disastrous, as it cost D’Entrecasteaux his life, and those of two of his lieutenants, besides several of his crew. Captain Dillon, a shrewd old Pacific sailor, was the first to find unmistakable traces of the wrecks. On the 15th of May, 1824, his vessel, the St. Patrick, passed close to Tikopia, one of the New Hebrides. There a Lascar came alongside in a canoe, sold him the handle of a sword in silver that bore the print of characters engraved on the hilt. The Lascar pretended that six years before, during a stay at Vanikoro, he had seen two Europeans that belonged to some vessels that had run aground on the reefs some years ago. 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.
