Another reason Jefferson decided to order him out west was Lewis’s unusually sympathetic awareness of America’s aboriginal people. Lewis already had firsthand knowledge of various Indian tribes: the Cherokee in Georgia, where he had lived as a young man; the Chickasaw and the Shawnee when he was stationed as a soldier near modern-day Memphis; the Miami when he was involved in the mighty Battle of Fallen Timbers in far western Ohio; and later the Potawatomi near his army camp in lands close to today’s Detroit.

  At the time of Jefferson’s pouting decision, the Louisiana Purchase had not yet been consummated. The drapeau tricolore still flew on the far side of the Mississippi. There was also evidence that maybe Britain was about to make some kind of claim on the territory too, leading to a certain urgency. Lewis had to leave, it was decided, and in double-quick time.

  The depth of ignorance of the soon-to-be-acquired territory was profound. Its precise borders were unknown, for a start—and the French had made it abundantly clear they were not going to give Americans any information about them. Lewis and the party he would choose would have to start essentially from scratch. Where were the land’s natural frontiers, where were the mountain ranges, and how exactly did its rivers twist and turn down from the hilltops to the sea? They would have to find out. Moreover, were there truly, as stories of the time suggested, great peaks out in the vastness that were made entirely out of salt? Where were the territory’s snowfields, its deserts, the pastures and the prairies? What kinds of flowers and trees grew there, and what species of animals, which types of birds?

  And who exactly were the peoples—the Indians, as Columbus had supposed—who had belonged to the land before? Was it true, as some said, that many of them were Welsh? Or, according to others, the Lost Tribes of Israel? And whoever they might be, where did they now live and have their being?

  By March 1803 the necessary congressional authorization for the venture was in hand. A sum of $2,500 was appropriated—with $696 set aside for gifts to the natives. A month later and the transfer papers were formally signed in Paris, and the land that had so intrigued Jefferson was now fully American owned and so could be legally explored.

  Lewis, now certain the expedition was to begin, procured a note of limitless credit signed by President Jefferson himself as a guarantee, just in case they ran out of cash. He then began assembling his gear. He found his rifles at an army arsenal in Virginia. He found builders for an iron-framed fifty-five-foot wooden keelboat in Pittsburgh. He found his ammunition, his trinket gifts, and his comestibles in Philadelphia. He had to imagine what else he might need: mosquito nets, waterproof lead tubes for holding ammunition, various bibelots and silver medallions struck with Jefferson’s profile to be handed out as marks of amity to the encountered Indians, large quantities of powdered ink, 193 pounds of dried soup, twenty-five axes, and four gross of fishhooks. He also took instruction in field medicine—mainly from a doctor of somewhat crabbed views who believed most ailments could be cured by powerful laxatives, especially one made of mercuric chloride and a ground-up Mexican purgative root named jalap.

  With the gear assembled, it was now time to gather the men. In June, shortly before the secretary of war gave formal authorization on July 2 for the corps to select volunteers for the expedition from any of his army garrisons along the Ohio, Lewis wrote to his old army friend William Clark, offering him the position of joint leader of the expedition. The latter accepted cheerfully: “This is an undertaking fraighted with many difeculties, but My friend I do assure you that no man lives whith whome I would prefur to undertake Such a Trip.”

  Clark was four years older and, in their previous encounter, had been the senior officer. Clark was more rough-hewn and both less literate and by all accounts less given to dark moods than Lewis. Clark had been tested in battle with Indians, while Lewis had not. And Lewis was very much Jefferson’s protégé, while Clark had barely a nodding acquaintance with the president. Nevertheless, the pair—who joined up in the Ohio River town of Clarksville, Indiana, in October to begin their formal collaboration—got on famously well on just about every day of the 856 they would spend away together.

  In Clarksville they assembled their full team, the soldiers chosen from the scores of fort-weary volunteers ready for an opportunity of real excitement. In the end some twenty-nine men, including Clark’s slave, York, were sworn in for the duties ahead.

  There were ten weeks of training and preparation before the team was prepared to start. History records with some precision the formal beginning of the expedition: three thirty in the afternoon of Monday, May 21, 1804.

  By now the winter was well over; the ice was gone, and the rivers were brimming with snowmelt. Having crossed the Mississippi separately, Lewis rejoined Clark some slight way along its principal tributary, the Missouri. The place he chose was the village of Saint Charles, a threadbare settlement on the river’s north bank with a population of about four hundred, most of them French Canadians.

  There was a simple topographic reason for the choice of the expedition’s starting point. Close to the junction of the two streams, there was a mess of fluvial indecision, with the tributary rivers swiveling direction at the behest of their conjoined currents, leaving a maze of swamps and oxbow lakes and blind-alley bays all across the landscape. But in Saint Charles, the Missouri seemed at last to start pulling itself firmly away to the west—the direction in which the expedition wanted to go.

  The river’s course was directed by the local geology—the same geology that also enticed the first settlers. There was a low bluff of Devonian sandstone hills on the river’s northern bank, the first elevated ground west of its junction with the Mississippi, which would both keep any settlers safe from floods and, in case of attack, offer their pickets a good view of the waters downstream. So a cluster of buildings was built along the bluff—a Catholic chapel, a hundred poorly made houses, a few shops. All of them looked southward across the deep brown stream—the Big Muddy, as it would later be widely called (Clark claimed to find a wineglassful of ooze in every pint of Missouri river water)—toward the scattering of houses in distant Saint Louis, toward the familiar and the known.

  Behind, beyond their village pale, was the true unknown—a terra incognita of brown Indian hills, expanses of lands unfamiliar and potentially hostile. Hunters and trappers ventured there—but no settlers, not yet. Saint Charles was thus for many years the most westerly European settlement, the last bastion of immigrant civilization, a town that lay at the very point of intersection between settled America and untamed native lands of the frontier. It could scarcely have been more appropriate as a departure point.

  A thunderstorm was raging when Lewis arrived from Saint Louis. He took what churchly men still charmingly called a cold collation—a snack, allowed on fast days—and then crossed the river, where he found Lieutenant Clark and his party encamped for the evening. Most of the party (except for one member, who the night before had received fifty lashes for going AWOL and then displaying “behavior unbecoming” at a party) were “in good health and sperits.” Small wonder: Clark had been royally looked after during his four-day stay: the local Gallic swells offered far better food and wine than had ever been available back east, together with invitations to balls and visits to his boats by numbers of ladies of the town.

  One could imagine that Clark would have rather liked to stay, but just after lunch the next afternoon, they set off—“under three Cheers,” wrote Clark, “from the gentlemen on the bank.”

  They headed first directly toward the west, toiling against a slow river current and the whirling of the deadly water-boils they would endure for the next fifteen months, and until they eventually crossed the unknown, unimagined wilderness of the Continental Divide after more than three thousand miles of travel.

  They spent the first six weeks journeying easily enough through what is now the state of Missouri. During the early miles, a number of limestone cliffs and sandstone bluffs rise up beside the stream—indeed, Clark fell
from one three-hundred-foot pinnacle early in the trip, saving himself only by digging his knife into a crevice and dangling there until he felt brave enough to clamber back up. But generally the countryside here is more floodplain than valley, more prairie than canyon, and the river winds and wanders irrationally, all over the place.

  The party found they were making only minimal forward progress, even though their daily distances turned out to be wearyingly long. Today the highways and the Union Pacific rail lines follow much the same exhausting path along the riverbank. They do so not because contour lines compel them to, but because if they tried to go straight where the river winds—with every single bend given a name, Bushwhacker Bend, Bootlegger Bend, Cranberry Bend—far too many costly bridges would be required. It is more prudent and economical to follow the stream than to fight it, today just as it was back in the expedition’s time.

  THE FRONTIER AND THE THESIS

  After some weeks of sailing and rowing and poling along a willow-banked river, the party reached a junction, with a river they called the Kaw, today the Kansas River. The leaders were at last quite impressed with the landscape—“the countrey about the mouth of this river is verry fine,” wrote Clark, and said it would be a good site for a future army fort.

  The army must not have agreed, but civilian settlers eventually did, in their thousands, for they later turned the spit of land between the two streams into an enormous campsite, a base for the long and heroic westward treks along the Oregon Trail, the Santa Fe Trail, and the California Trail. And the metropolis that some of their number then stayed behind to build, Kansas City, has become a classic of frontier America.

  I had been here before, some thirty years earlier. It was shortly before the bicentennial celebration of 1976, when I spent six months traveling through the Midwest, trying to understand the importance of that uniquely American phenomenon, the frontier. Along the way I had met many people and had seen many things: two of the more memorable happened to be right here, where Lewis and Clark were pressing westward through the very frontier I was studying.

  The first encounter was of rather lesser importance, though it still had some poignancy. I had been invited to visit a marble memorial to an enormous white Charolais bull. He was named Sam 951, and until 1972 he had lived on a ranch in the town of Chillicothe and had been famous for miles around as an example of bovine excellence. Sam’s frozen semen, once produced in exuberant gallons by what all agreed was an excessively jolly creature, was worth millions, and was packaged in nitrogen-cooled vials to be sent off from Chillicothe to eager customers all over the world.

  The Litton Charolais Ranch was in consequence once perhaps the most profitable cattle-breeding outfit in America. Sam 951 was primus inter pares of the large and carefully managed herd. Each bull—the best of them lived in air-conditioned barns kitted out with red carpets—weighed a ton or more, had ears the size of dinner plates, had a vast muscular body joined necklessly to an appropriately immense head, and sported dewlaps that would take two strong hands to move.

  Cattle like Sam had made a great fortune for the ranch owner, Jerry Litton, and had now brought him within a hair’s breadth of true fame. I spent two happy summer days with him—a handsome and engaging man who had married a former Miss Chillicothe (and a runner-up in the Miss Missouri pageant) and who for the previous four years had been a member of the US Congress, a Democrat. His home at the time I stayed was abuzz with political excitement: in two weeks voters were due to decide whether or not to elect him a US senator. Many, indeed, thought he would and should run for national office—President Jimmy Carter was a supporter—and in early 1976 he was sufficiently intrigued to announce that he would indeed take this obvious next step along the political glide path.

  When I turned up, his work was nearly all wrapped up. He was in the closing stages of what all agreed had been an impeccably nuanced and well-funded campaign for the primary election. And two weeks after I left, he did indeed triumph, leading a stunning upset in a twelve-man primary race. Jerry Litton was on the verge, I have long since believed, of well-deserved political greatness.

  On the night of his victory, he was to be flown back to Kansas City for a celebration. But then came calamity. The crankshaft in one of the engines sheared in half; the little plane lost power and crashed on takeoff; and Litton, his wife and children, his Beech Baron’s pilot, and the pilot’s son were all killed. Jerry Litton had been born in a house without electric power, in 1937, when this part of Missouri still had the feel of the frontier about it. He would have brought something of this spirit to Washington had fate permitted it. He was a figure of whom it can rightly be said, He could have been a contender. But fate saw to it that he never got the chance.

  My second excursion of that 1976 adventure concerned the polar opposite of a cattle farm. I spent time touring a sprawling Minuteman nuclear missile site, centered at the Whiteman US Air Force Base, an immense complex of men and their flying machines set close by a village just south of the river with the engaging name of Knob Noster. Back in the 1970s, it was quite possible to visit the immense missiles and to descend deep into the bunkers where clean-cut young officers—curiously decked out in uniforms that included starched white ascot collars—sat beside their pairs of launch switches, enduring a bleak shift of existence in air-conditioned subterranean silence, waiting to execute a world-destroying command that, mercifully, never came.

  The Cold War is now over, but America still has deployed around the country three wings of Minuteman missiles, all nuclear tipped and more powerful than ever, as ready to go as ever they were before. They are, however, no longer deployed in Missouri but in more distant and protected wilderness bases in North Dakota, Wyoming, and Montana. One can still try walking across lonely Montana meadows up to the edge of the wire-protected silo where a missile lurks beneath its concrete blast doors, to test how long it takes before a security jeep or a helicopter, with flashing blue lights and a crew of soldiers with full authority to maim, comes to find out what you are up to. Back in Missouri in the 1970s, I was invited to try and found it took no more than a couple of minutes for my breach of security to be discovered and repulsed. But it is no longer possible to play such a game at the Whiteman Base there since the men have all been stood down and their missiles dismantled and destroyed under the terms of the various treaties signed with a Russia that is no longer the Soviet Union, no longer seen as quite the threat it once was.

  Yet Whiteman Air Force Base itself still exists, and if not armed with missiles today, it still sports a title and wields an ability that sends chills down spines. It is part of a terrifying arsenal of weaponry that is now called—after numerous organizational changes and semantic alterations of title—the United States Air Force Global Strike Command.

  The command has its headquarters in Louisiana, from where it controls all of America’s air-launched atomic weapons—the three Minuteman missile wings in the northwest and a large number of B-2 stealth bombers, all of them designed to drop thermonuclear bombs. The bulk of these bombers happen to be based at Whiteman—at a site a short way from that point on the river where, in 1804, William Clark recorded hearing an “emence snake” that inhabits a small lake nearby “and which gobbles like a Turkey & may be herd several miles.”

  The planes belong to a US Air Force wing, the 509th, that proudly reminds visitors that it is the direct descendant of the only unit in history that has ever dropped live atomic bombs in wartime, on Hiroshima and Nagasaki in 1945. Today it is a battle-proven assemblage of aircraft and crew that, its commander says, can now bring massive firepower to bear, in a short time, anywhere on the globe.

  There seems a certain irony in this nuclear firebase being located so very close to the Lewis and Clark
expedition route, not least because what Jefferson’s explorers were seeking to do, even if unknowingly at the time, was tied to the unique American concept of the frontier and to the development of what to this day is known—and argued over—as the frontier thesis. The irony stems from the argument that the frontier mentality, if such a thing truly exists, still plays a nourishing—and controversial—role at the intellectual roots of much of today’s American foreign policy.

  The famous argument, put forward in an 1895 paper by a University of Wisconsin history professor, Frederick Jackson Turner, held that there was an immense social significance in the simple existence of the frontier—that ever-westward-shifting margin between civilized society in the East and the untamed savagery and wilderness to the West. Kansas City, the city that rose from one of the campsites of the Lewis and Clark Expedition, became a classic, if momentary, point of frontier contact: on its eastern side were traders, trappers, farmers, settlers, surveyors, villages, and towns; on its western side were empty prairies, nomads, lawlessness, and an unprotected and shelterless void of stony plains, tornadoes, and starvation. Between them lay the line of contact, division, and separation: the frontier.

  The rolling clash between these two extremes gave rise, Turner argued, to a peculiarly American set of character traits. The experiences suffered or enjoyed on the frontier left Americans inherently different from what they and their antecedents had been in their homelands. Those tested in the borderlands were by comparison more violent, more informal, more democratic, more imbued with personal initiative, and less hamstrung by tradition, class, and elegance. More American, Turner suggested. Strength, power, might—the ability to tame rather than to persuade, the tendency to demand rather than request, the tendency to shoot rather than to talk—these were all tendencies compounded by the frontier experience, uniquely different building blocks employed in the making of the modern American. The Western myth, the legends of the cowboy, the cinematic and entertainment-park allure of concepts like Frontierland—all of these were born from this single simple (some would say simplistic) thesis offered by Frederick Jackson Turner.
