Just then Captain Nemo asked me what I knew about the shipwreck of the Count de La Pérouse.

"What everybody knows, captain," I answered him.

"And could you kindly tell me what everybody knows?" he asked me in a gently ironic tone.

"Very easily."

I related to him what the final deeds of Captain Dumont d'Urville had brought to light, deeds described here in this heavily condensed summary of the whole matter.

In 1785 the Count de La Pérouse and his subordinate, Captain de Langle, were sent by King Louis XVI of France on a voyage to circumnavigate the globe. They boarded two sloops of war, the Compass and the Astrolabe, which were never seen again.

In 1791, justly concerned about the fate of these two sloops of war, the French government fitted out two large cargo boats, the Search and the Hope, which left Brest on September 28 under orders from Rear Admiral Bruni d'Entrecasteaux. Two months later, testimony from a certain Commander Bowen, aboard the Albemarle, alleged that rubble from shipwrecked vessels had been seen on the coast of New Georgia. But d'Entrecasteaux was unaware of this news--which seemed a bit dubious anyhow--and headed toward the Admiralty Islands, which had been named in a report by one Captain Hunter as the site of the Count de La Pérouse's shipwreck.

They looked in vain. The Hope and the Search passed right by Vanikoro without stopping there; and overall, this voyage was plagued by misfortune, ultimately costing the lives of Rear Admiral d'Entrecasteaux, two of his subordinate officers, and several seamen from his crew.

It was an old hand at the Pacific, the English adventurer Captain Peter Dillon, who was the first to pick up the trail left by castaways from the wrecked vessels. On May 15, 1824, his ship, the St. Patrick, passed by Tikopia Island, one of the New Hebrides. There a native boatman pulled alongside in a dugout canoe and sold Dillon a silver sword hilt bearing the imprint of characters engraved with a cutting tool known as a burin. Furthermore, this native boatman claimed that during a stay in Vanikoro six years earlier, he had seen two Europeans belonging to ships that had run aground on the island's reefs many years before.

Dillon guessed that the ships at issue were those under the Count de La Pérouse, ships whose disappearance had shaken the entire world. He tried to reach Vanikoro, where, according to the native boatman, a good deal of rubble from the shipwreck could still be found, but winds and currents prevented his doing so.

Dillon returned to Calcutta. There he was able to interest the Asiatic Society and the East India Company in his discovery. A ship named after the Search was placed at his disposal, and he departed on January 23, 1827, accompanied by a French deputy.

This new Search, after putting in at several stops over the Pacific, dropped anchor before Vanikoro on July 7, 1827, in the same harbor of Vana where the Nautilus was currently floating.

There Dillon collected many relics of the shipwreck: iron utensils, anchors, eyelets from pulleys, swivel guns, an eighteen-pound shell, the remains of some astronomical instruments, a piece of sternrail, and a bronze bell bearing the inscription "Made by Bazin," the foundry mark at Brest Arsenal around 1785. There could no longer be any doubt.

Finishing his investigations, Dillon stayed at the site of the casualty until the month of October. Then he left Vanikoro, headed toward New Zealand, dropped anchor at Calcutta on April 7, 1828, and returned to France, where he received a very cordial welcome from King Charles X.

But just then the renowned French explorer Captain Dumont d'Urville, unaware of Dillon's activities, had already set sail to search elsewhere for the site of the shipwreck. In essence, a whaling vessel had reported that some medals and a Cross of St. Louis had been found in the hands of savages in the Louisiade Islands and New Caledonia.

So Captain Dumont d'Urville had put to sea in command of a vessel named after the Astrolabe, and just two months after Dillon had left Vanikoro, Dumont d'Urville dropped anchor before Hobart. There he heard about Dillon's findings, and he further learned that a certain James Hobbs, chief officer on the Union out of Calcutta, had put to shore on an island located in latitude 8 degrees 18' south and longitude 156 degrees 30' east, and had noted the natives of those waterways making use of iron bars and red fabrics.

Pretty perplexed, Dumont d'Urville didn't know if he should give credence to these reports, which had been carried in some of the less reliable newspapers; nevertheless, he decided to start on Dillon's trail.

On February 10, 1828, the new Astrolabe hove before Tikopia Island, took on a guide and interpreter in the person of a deserter who had settled there, plied a course toward Vanikoro, raised it on February 12, sailed along its reefs until the 14th, and only on the 20th dropped anchor inside its barrier in the harbor of Vana.

On the 23rd, several officers circled the island and brought back some rubble of little importance. The natives, adopting a system of denial and evasion, refused to guide them to the site of the casualty. This rather shady conduct aroused the suspicion that the natives had mistreated the castaways; and in truth, the natives seemed afraid that Dumont d'Urville had come to avenge the Count de La Pérouse and his unfortunate companions.
