La Perouse

[john sefton]

Jean-François de Galaup was born near Albi, France. La Pérouse was the name of a family property that he added to his name. He studied in a Jesuit college and entered the naval college in Brest when he was fifteen. He fought against the British off North America in the Seven Years' War. In the beginning of the war he was wounded in a naval engagement off the French coast and was briefly imprisoned.
Following the Franco-American alliance, he fought against the Royal Navy off the American coast, and victoriously led the frigate Astree in the Naval battle of Louisbourg, 21 July 1781. He was promoted to rank of commodore when he defeated the English frigate Ariel in the West Indies. In August 1782 he made his name by capturing two English forts (Prince of Wales Fort and York Fort) on the coast of Hudson Bay, but allowed the survivors, including Governor Samuel Hearne of Prince of Wales Fort, to sail off to England in exchange for a promise to release French prisoners held in England. The next year his family finally consented to his marriage of Louise-Eléonore Broudou, a young creole of modest origins whom he met on Ile de France (present-day Mauritius).
After the Treaty of Paris, La Pérouse was appointed in 1785 by Louis XVI and his minister of marine, the Marquis de Castries, to lead an expedition around the world. Louis XVI and his court had been stimulated by a proposal from the merchant adventurer William Bolts, who had earlier tried unsuccessfully to interest Louis’s brother-in-law, the Austrian Emperor Joseph II (brother of Queen Marie Antoinette), in a similar voyage. The French court adopted the concept (though not its author, Bolts) leading to the dispatch of the La Pérouse expedition. Charles Pierre Claret de Fleurieu, Directeur des Ports et Arsenaux, stated in the draft of the memorandum on the expedition he submitted to the King: “the utility which may result from a voyage of discovery … has made me receptive to the views put to me by Mr. Bolts relative to this enterprise”. But, Fleurieu explained to the King: “I am not proposing at all, however, the plan for this voyage as it was conceived by Mr. Bolts”. Its aims were to complete the Pacific discoveries of James Cook (whom La Pérouse greatly admired), correct and complete maps of the area, establish trade contacts, open new maritime routes and enrich French science and scientific collections. His ships were the Astrolabe (under Fleuriot de Langle) and the Boussole, both 500 tons. They were storeships, reclassified as frigates for the occasion. Their objectives were geographic, scientific, ethnological, economical (looking for possibilities of whaling or fur trading), and political (the eventual establishment of French bases or colonial cooperation with their Spanish allies in the Philippines). They were to explore both the north and south Pacific, including the coasts of the Far East and of Australia, and send back reports through existing European outposts in the area.
As early as March 1785, La Pérouse proposed that Paul Monneron, who had been chosen as the expedition's chief engineer, go to London to find out about the latest conclusions on the anti-scurvy measures recommended by Cook and the exchange items used by Cook in his dealings with the native peoples, and to buy scientific instruments of English manufacture.
The best-known figure on Cook's mission, Joseph Banks, intervened at the Royal Society to obtain him two inclining compasses that had belonged to Cook, and Monneron also bought scientific instruments figuring on a list produced by Fleurieu, having recourse to the largest English firms, particularly Ramsden. He even surpassed Fleurieu's directives by acquiring two sextants of a new type.
La Pérouse tried to get on well with the Pacific islanders, and was well-liked by his men. Among his 114-man crew there were ten scientists: Dagelet, an astronomer and mathematician; Robert de Lamanon, a geologist; La Martinière, a botanist; a physicist; three naturalists; and three illustrators, Gaspard Duché de Vancy and an uncle and nephew named Prévost. Another of the scientists was Jean-André Mongez. Even both chaplains were scientifically schooled.
One of the men who applied for the voyage was a 16-year-old Corsican named Napoléon Bonaparte. Bonaparte, a second lieutenant from Paris's military academy at the time, made the preliminary list but he was ultimately not chosen for the voyage list and remained behind in France. At the time Bonaparte was interested in serving in the navy rather than army because of his proficiency in mathematics and artillery, both valued skills on warships. (One can only speculate on the course history might have taken had La Pérouse selected young Napoleon for the trip.)
Copying the work methods of Cook's scientists, the scientists on this voyage would base their calculations of longitude on precision watches and the distance between the moon and the sun followed by theodolite triangulations or bearings taken from the ship, the same as those taken by Cook to produce his maps of the Pacific islands. As regards geography, Lapérouse decisively showed the rigour and safety of the methods proven by Cook. From his voyage, the resolution of the problem of longitude was evident and mapping attained a scientific precision. Impeded (as Cook had been) by the continual mists enveloping the northwestern coast of America, he nevertheless did not succeed any better in producing complete maps, though he managed to fill in some of the gaps.
Alaska and California
He and his 20 men left Brest on 1 August 1785, rounded Cape Horn, investigated the Spanish colonial government in Chile, and, by way of Easter Island (where he arrived on 9 April 1786) and Hawaii (where he became the first European to set foot on the island of Maui), sailed on to Alaska, where he landed near Mount St. Elias in late June 1786[] and explored the environs. On 13 July 1786 a barge and two longboats, carrying 21 men, were lost in the heavy currents of the bay called Port des Français by La Pérouse, but now known as Lituya Bay. Next, he headed south, exploring the northwest coast all the way to Monterey. Along the way, he explored the outer islands of British Columbia (August 10-30) and reportedly observed the only historical eruption of Mount Shasta on 7 September 1786. He arrived in Monterey on 14 September 1786. where he examined the Spanish settlements and made critical notes on the treatment of the Indians in the Franciscan missions.
He again crossed the Pacific Ocean in 100 days, arriving at Macau, where he sold the furs acquired in Alaska, dividing the profits among his men. The next year, on 9 April 1787, after a visit to Manila, he set out for the northeast Asian coasts. He saw the island of Quelpart (Cheju), which had been visited by Europeans only once before when a group of Dutchmen shipwrecked there in 1635. He visited the mainland coast of Korea, then crossed over to Oku-Yeso (Sakhalin).
Japan and Russia
The inhabitants had drawn him a map, showing their country, Yeso (also Yezo, now called Hokkaidō) and the coasts of Tartary (mainland Asia). La Pérouse wanted to sail through the channel between Sakhalin and Asia, but failed, so he turned south, and sailed through La Pérouse Strait (between Sakhalin and Hokkaidō), where he met the Ainu, explored the Kuriles, and reached Petropavlovsk (on Kamchatka peninsula) on 7 September 1787. Here they rested from their trip, and enjoyed the hospitality of the Russians and Kamchatkans. In letters received from Paris he was ordered to investigate the settlement the British were to erect in New South Wales. Barthélemy de Lesseps, the French vice consul at Kronstadt, who had joined the expedition as an interpreter, disembarked to bring the expedition's letters and documents to France, which he reached after a year-long, epic journey across Siberia and Russia.
Pacific
His next stops were in the Navigator Islands (Samoa), on 6 December 1787. Just before he left, the Samoans attacked a group of his men, killing twelve of them, among whom were Lamanon and de Langle, commander of the Astrolabe. Twenty men were wounded. The expedition continued to Tonga and then to Australia, arriving at Botany Bay on 24 January 1788, just as Captain Arthur Phillip was attempting to move the colony from there to Sydney Cove in Port Jackson. The First Fleet was unable to leave until 26 January because of a tremendous gale, which also prevented La Pérouse's ships from entering Botany Bay. The British received him courteously, and each captain, through their officers, offered the other any assistance and supplies he may need. He and Phillip did not meet personally. La Pérouse sent his journals and letters to Europe with a British ship, the Sirius, obtained wood and fresh water, and on 10 March left for New Caledonia, Santa Cruz, the Solomons, the Louisiades, and the western and southern coasts of Australia. Although he wrote that he expected to be back in France by June 1789, neither he nor any of his men were seen again. Fortunately, before he set sail, La Pérouse had sent the valuable written details of his expedition to Paris where they were published posthumously.
