Medicine: Lewis purchased fifty-five dollars worth of medicines, including Epsom salts, emetics, opium, peruvian bark (contained quinine), lancets for bleeding, a syringe for enemas, and 4 penal syringes to treat venereal disease. They took along 1300 doses of Dr. Benjamin Rush’s powerful laxative called “thunderclappers” or “thunderbolts.”  It was frequently administered, “never failing to have the desired effect.”

Native Americans: One source says forty-eight tribes, others say fifty or more. They provided the Corps food, shelter, knowledge, and friendship, except for the Teton Sioux in South Dakota and the Blackfeet in Montana.

Pacific Ocean: Clark recorded on November 7, 1805: “Great Joy in camp we are in view of the Ocian this great Pacific Octean. . .”  Actually they were looking at the Columbia River estuary; the ocean was still about twenty direct-line miles away.   Journal keeper Joseph Whitehouse on the sixteenth announced: “We are now in plain view of the Pacific Ocean.”

Personnel: From Camp Wood to the Mandan Villages, the exact figure is difficult to establish.

 Leaving Camp Wood there were two captains, three sergeants, one corporal, twenty-four privates, plus York (Clark’s slave).  In addition a number of engagés left with them.  Most were French-Canadians hired for their knowledge of the Missouri River and Indian languages.  Forty-two to forty-five or more men departed from Camp Wood, with changes along the way to the Mandan villages.

From the Mandan Villages to the ocean, the permanent party numbered thirty-three:  the two officers, three sergeants, twenty-three privates, Charbonneau and Drouillard, York, Sacagawea and her son Jean-Baptiste.

Weapons: It is often asserted that Lewis acquired at Harpers Ferry at least fifteen new model 1803 rifles, fifty-four caliber guns especially designed for the army, called short barreled (thirty-three inches long but shorter than the longer civilian "Pennsylvania" rifles).  A contrary view maintains that the rifles he acquired were in fact Model 1792 rifles, ten inches longer than the 1803 rifles. The original locks on these weapons had been replaced with locks bearing the date of 1803. Some of the men carried their own "Kentucky" or "Pennsylvania" sixty-nine caliber long rifles. In addition, both pirouges had a blunderbuss swivel gun, weapons with approximately twenty-four-inch barrels and two-inch flared muzzles. Described as scatterguns they were capable of firing about anything put into them. 

A small cannon (called the “large swivel”) was mounted on the bow of the keelboat, firing buckshot or a single ball. The iron ball weighed about one pound, fired from a bore of about two inches. The cannon was presented as a gift to a Hidatsa chief on the return trip to St. Louis.

 Lewis had an air rifle that he used to impress observers when he fired his virtually silent weapon. He also carried a six foot one inch wooded shaft with an iron blade and tip called an espontoon that he used as a walking stick, weapon, and rifle support. 

The men’s armament included large knives and tomahawks.

What Was Discovered: Jefferson’s primary instruction to Lewis was to “explore the most direct & practicable water communication across this continent, for the purposes of commerce.” The President reiterated the point in a January 1804 letter to Lewis, stressing that “The object of your mission is simple, the direct water communication from sea to sea. . . .” 

 Some two and a half years later, having returned to St. Louis, Lewis writes what first appears to be a mission accomplished report, informing the anxious President that “we have discovered the most practicable rout which does exist across the continent by means of navigable branches of the Missouri and Columbia rivers.”  Then the explorer goes on to describe that this most “practicable rout” is in fact totally impractical.

 Jefferson recognized before the expedition that there was no continual waterway to the west as he directed in his instructions that points of portage between the Missouri and waters to the Pacific should be “fixed by observation.”  In accord with geographic lore of the day, he expected portages to be short and achieved without great difficulty.  Now he learns that it is necessary to go by boat 2,575 miles up a river with caving banks and other dangers to the foot of the Great Falls. There an eighteen-mile portage waits, then two hundred not particularly difficult miles, but followed by one hundred forty miles of “tremendious” mountains, sixty miles of which “are covered with eternal snow.”  After a last leg of six hundred boat miles with additional portages and “three roaring cascades” the Pacific is finally reached. Lewis and Clark’s expedition brought to an end the time-honored search for a Northwest Passage.

 The short-term effects of the mission were negligible. The Corps of Discovery's long absence led to the assumption its members had perished during the journey.  On their way back to St. Louis, they encountered several traders and trappers on their way up the Missouri River who knew nothing about the Corps of Discovery.  As news of their return spread, Lewis and Clark were wined and dined, but they soon faded from public view.  Lewis was supposed to provide a manuscript for publication of the journals, but died without doing so.  When Nicolas Biddle’s narrative of the journals did appear eight years  after Lewis and Clark's return, its impact was slight.  Their scientific data, their botanical and animal records, were not included.  Not until  1904 was a more complete edition of the journals published, including Lewis and Clark’s scientific data and some maps.

 The pioneers who headed west did not follow in their footsteps.  Lewis and Clark's hazardous and laborious route was not suited for families in covered wagons heading for California and Oregon in the last half of the nineteenth century.  Therefore, they took the famed Oregon Trail, following the flatlands of the Platte River and crossed not the Bitteroot Mountains of The Rockies, but the manageable South Pass in Wyoming.  The movement west and the American frontier were history by the time the Corps of Discovery was discovered.  Not until the 1960s did the Lewis and Clark Expedition become a subject of widespread interest, largely because of Steven Ambrose's Undaunted Courage and the recognition of multiculturism in the American experience. Now the contributions of York, the Black slave, the Native-Americans, and the French Canadians to the success of the mission have been acknowledged.  In the early nineteenth-century, Sacagawea had emerged as an important member of the Expedition, thanks to the Progressive era and women’s activism stressing her role.

"If Lewis and Clark had died on the trail," says Notre Dame Historian Thomas Slaughter, "it wouldn't have mattered a bit."

Was the mission a failure for not having found the waterway to the Pacific?  No, because proving that it did not exist was a momentous contribution to geographic knowledge.

Although not appreciated for many years, many other achievements followed in the wake of the Corps of Discovery.  Henceforth, the United States had a primary claim to the territory from the Continental divide to the Pacific Ocean, although contested for years.   The journal’s pages recorded for the first time the manifold and detailed results of the natural and social science missions Jefferson assigned.  They reveal a geographic wonderland of mountains, rivers, and wildlife, populated with diverse peoples engaged in large-scale trade patterns, and possessed of civilizations. The Northwest was rich in human, animal, and plant life.

 They dispelled many myths about the western territories, There were no mammoths, no Welsh Indians, no active volcanoes.  Blank spaces on maps previously marked “unknown” were now known and charted.

 In 2004, the United States inaugurated its Bicentennial Commemoration of the Lewis and Clark Expedition. It acknowledges that the men and woman of the Corps of Discovery bequeathed to Americans their epic story. They confronted together months of treacherous waters, threatening animals, geographic obstacles, hunger, temptations, elation and disappointments while facing the uncertainties of the unknown.  Their voyage into the wilderness revealed qualities that came to embody the American Spirit:  courage, persistence, endurance, teamwork, admirable leaders, and the value of imagination and exploration.  The Lewis and Clark Expedition heralds what people working together can accomplish, even against great odds.

 But a high price has been paid.  Native-Americans, whose assistance made success possible, have been ill paid for their contributions.  Their numbers have been decimated, their land taken, their beliefs impugned, their dignity assaulted.  The natural resources of the territory have been despoiled and like its peoples, its once bountiful animal and plant life endangered—the fate of the buffalo tells us much about our “stewardship.”  The Bicentennial Commemoration of the Lewis and Clark Expedition highlights that  reconciliation among peoples and achieving harmony between nature and humanity are long overdue.
