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.
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
