was on the verge of departure. The aim of the first two voyages was largely strategic: Byron was to stake a claim to the Falkland Islands, examine the coast of New Albion (California), and look for a Northwest Passage; Wallis was to search for a continent between New Zealand and Cape Horn. But the goal of the third voyage was explicitly scientific: to carry a crew of scientists to a location from which they would be able to observe a celestial event known as the transit of Venus.
A transit of Venus occurs when the planet Venus passes between the earth and the sun. It was of interest to eighteenth-century astronomers because accurate measurements of the event’s duration could be used to calculate the size of the solar system, thereby answering one of the burning astronomical questions of the age. Unfortunately, the transit of Venus occurs only infrequently: twice in a period of eight years and then not again for a century or more. It was observed for the first time in 1639 (having passed unnoticed in 1631) and did not occur again in the seventeenth century. Late-eighteenth-century astronomers knew they would have two bites at the cherry—one in 1761 and another in 1769—after which their chances would be over, since it would not come again until 1874. A major international effort to document the transit of 1761 had produced disappointing results, and in the years leading up to 1769, members of the international scientific community, including Britain’s Royal Society, mounted a major campaign to ensure that the last opportunity of their lifetimes would not be lost.
An important consideration in all of this is where on the earth the transit can be seen, since it is fully visible only from those places that are in daylight for the duration of the event. In 1761, this had included most of the Eurasian continent, but in 1769 the ideal place from which to observe it was, most inconveniently, the middle of the Pacific Ocean. The only suitable islands known to fall within the “cone of visibility” were, on the eastern end, the Marquesas, last seen in 1595 and none too securely charted, and, in the west, the islands of Tonga, last visited by Abel Tasman in 1642. Between these, so far as anyone knew, there were only low coral atolls with terrible reefs and not a single safe harbor, and no reliable sources of food or water. Still, the Royal Society was committed, and plans were drawn up for an expedition with a final destination to be determined.
The man chosen to lead this expedition was a little-known lieutenant with a solid if undistinguished naval career and a reputation for being extremely good at survey work. At forty years of age, James Cook was not young, nor was he a man of rank or birth. He was tall, strong-featured, intelligent, disciplined, and extremely hardworking. Though largely self-taught, he was known as a talented mathematician and admired for his astronomical work, including an observation of a solar eclipse made while he was surveying the coast of Newfoundland. The voyage for which he had been selected was also somewhat out of the ordinary for a Royal Naval expedition. With only one ship (and a small one at that) and a very great distance to be covered, across a vast and largely uncharted sea, there was potential for glory but also significant risk.
The commander appointed, a suitable vessel was selected and rechristened the H.M.S. Endeavour, and a complement of sailors, scientists, and supernumeraries were named. These included the lively and observant young gentleman Joseph Banks—“one of the spoilt children of fortune,” as his biographer affectionately dubs him—who traveled as a passenger at his own expense, with an entourage consisting of two artists, a secretary, four servants, and a pair of dogs. But with just two and a half months to go before the Endeavour’s departure, the expedition still had no clear destination. And then, out of the salt-stained blue, the Dolphin returned, bringing news of an unexpected discovery.
THE DOLPHIN HAD been sent out under the command of Captain Wallis to scour the southern reaches of the Pacific Ocean. Wallis’s instructions directed him to sail west from Cape Horn for 100 to 120 degrees of longitude (some four to five thousand miles), a course that, had he been able to maintain it, would have brought him all the way to New Zealand. This was plainly impossible, given the strength and direction of the prevailing winds. Emerging into the Pacific from the Strait of Magellan, he was pushed north even as he tried to sail west, and his first sight of anything at all was in the Tuamotus. There was nothing surprising about this—a landfall in the Tuamotu Archipelago was by now to be expected. But Wallis’s path intersected the island chain at a point somewhat south of the routes taken by his predecessors, and this put him on the path to one of the most significant landfalls of the eighteenth century: “The island of Tahiti, famous name, the heart of Polynesia.”
Tahiti is the largest of a group of high islands known collectively as the Society Islands. They are located in the very center of the Polynesian Triangle and consist of two clusters: a windward group, which includes Tahiti and Mo‘orea, and a leeward group, which includes Ra‘iatea and Bora Bora. While not objectively large, they are large for islands in this part of the sea; Tahiti itself, though less than forty miles long, is the largest landmass for a thousand miles in any direction. To the modern eye, the Society Islands are perhaps the most striking omission on early maps of the Pacific—the islands it is hardest to believe no one had yet found. In fact, Magellan, Mendaña, Quirós, Schouten and Le Maire, and Byron had all sailed right past them, sometimes at a distance of less than a hundred miles. Roggeveen even caught sight of the peaks of Bora Bora, assumed it was an island discovered by someone else, and inexplicably sailed on.
From the European point of view, the discovery of Tahiti was a dramatic and fortuitous event. Not only had Wallis located an island that was right in the center of the cone of visibility for the 1769 transit of Venus, it was the island of a navigator’s dreams. Tahiti is mountainous, like the Marquesas, but, with its habitable coastline, fringing reef, and long stretches of crystalline blue lagoon, its topography is considerably more congenial. Its location, about 2,500 miles due south of Hawai‘i, is also meteorologically ideal: not too hot, not too dry, not too wet, not overly subject to hurricanes or typhoons. To the modern visitor it is delightful; to the eighteenth-century voyager it was a paradise on earth.
But, of course, such an island was bound to be inhabited, as indeed it was. When the crew of the Dolphin first sighted Tahiti, it appeared to them as a great cloud-covered mountain rising out of the sea. It was still many miles away at that point and, as evening was coming on, Wallis decided to put off his approach until morning. At daybreak he steered again for the island, but when the ship had come within six or seven miles, it was suddenly engulfed in fog. This, wrote the Dolphin’s master, George Robertson, “made us all very uneasy,” for by now they were close enough to hear the sea breaking and “making a great noice, on some reefs of Rocks.” This was nothing, however, next to the shock they received when the fog suddenly lifted to reveal not just a deadly row of breakers between the ship and the land but more than eight hundred men in canoes between the breakers and the ship.
Estimates of the pre-contact populations of Pacific islands vary widely, but in Tahiti at the time of the Dolphin’s arrival, there were probably something like 60,000 to 70,000 people, with perhaps 300,000 in the archipelago as a whole. Certainly enough to supply thousands of warriors and hundreds of canoes—Robertson would later describe the ship as being surrounded by more than five hundred canoes, manned, “at a Moderate Computation,” by four thousand men. The risks of trying to land on so populous an island were obvious, and there were those who believed—rightly, as it turned out—that “nothing could be hade without blows.” At the same time, many of the crew were so debilitated by scurvy that the prospect of sailing on was unthinkable, especially when the tantalizing scent of tropical vegetation wafted out to the ship during the night.
The Tahitians in their canoes paddled round Wallis’s ship, holding up plantain branches and making speeches and throwing the fronds into the sea. The British showed trinkets and made friendly signs and tried to entice the islanders on board. The Tahitians seemed cheerful and talked a great deal in a language that sounded to Robertson like that of the Patagonians of Tierra del Fuego (with which it had no relationship whatsoever). More and more canoes continued to arrive, and eventually a “fine brisk young man” scrambled up by the mizzen chains and leapt out of the shrouds onto an awning, where he stood, laughing and looking down on the quarterdeck. Soon more Tahitians were climbing aboard, looking around at everything and snatching whatever they could. After a while—the story is familiar—the Tahitians began to be “a Little surly,” the British grew nervous, and the next thing was the firing
