										<content:encoded><![CDATA[<p>The expedition is usually said to have ended when the Corps of Discovery reached St. Louis on September 23, 1806 &mdash; but Lorna Hainesworth documents a little-known coda. Traveling east to brief President Jefferson, Meriwether Lewis went ahead of William Clark through the Cumberland Gap, the great pass where Virginia, Kentucky, and Tennessee meet. There, on November 23, 1806, local gentlemen asked him to determine whether Dr. Thomas Walker&rsquo;s old line &mdash; by then the Kentucky&ndash;Tennessee boundary &mdash; actually lay where it was supposed to.</p>
<p>The paper reconstructs the return party (Sheheke, or Big White, and his family; the Pierre Chouteau&ndash;led Osage delegation; Clark&rsquo;s man York; privates Labiche and Frazier; and sergeants Gass and Ordway), the post roads they followed, and the long history of the Gap from Walker&rsquo;s 1750 sighting through Daniel Boone&rsquo;s Wilderness Road. It is a window onto Lewis the trained surveyor still at work, weeks after the journey west was over.</p>

										<content:encoded><![CDATA[<p>While researching connections between Maryland and the Lewis and Clark story, Lorna Hainesworth turned up a June 6, 1803 letter from Meriwether Lewis to William Linnard, the Army&rsquo;s military agent in Philadelphia &mdash; a document missing from Donald Jackson&rsquo;s standard <em>Letters of the Lewis and Clark Expedition</em> and overlooked by Ambrose, Cutright, and Dillon. The letter lays out, in exacting detail, how Lewis wanted his accumulated stores moved from Philadelphia and Harpers Ferry to Pittsburgh: the team and driver to hire, the route to follow, the schedule, the careful handling of his box of mathematical instruments, and how the expenses were to be accounted.</p>
<p>Read alongside four related 1803 letters (including the &ldquo;Portable Soup&rdquo; letter to General William Irvine), it reconstructs Lewis&rsquo;s spring-to-summer travels and introduces the cadre of quartermasters, purveyors, and armory officers &mdash; Israel Whelan, Thomas Cushing, Joseph Perkins, George Ingels, and Irvine &mdash; who outfitted the expedition. The find reveals Lewis at his logistical best: not only an explorer, but a meticulous quartermaster and project manager.</p>
<p>First published in the Lewis and Clark Trail Heritage Foundation&rsquo;s journal, <em>We Proceeded On</em> (August 2009). This summary is provided for reference on the Lewis and Clark Research archive; the full article is available at the source link.</p>

										<content:encoded><![CDATA[<p>The Corps of Discovery disbanded in 1806, but its members walked straight into the run-up to the War of 1812. Lorna Hainesworth gathers brief biographies of more than thirty expedition veterans and associates and traces what each did during the conflict. The sketches are organized into three groups: Corps military members (William Clark, John Colter, Patrick Gass, John Ordway, Nathaniel Pryor, George Shannon, William Bratton, Joseph Whitehouse, and others), Corps non-military figures (the Charbonneau family, Sacagawea, Jean Baptiste, and York), and associates ranging from Thomas Jefferson and Albert Gallatin to Pierre Chouteau, Manuel Lisa, Zebulon Pike, and William Henry Harrison.</p>
<p>Framing the sketches is a concise narrative of the war&rsquo;s origins &mdash; from the embargo years through the treaties of 1815 &mdash; along with an appendix on the presidents involved. It is a useful group portrait of where the expedition&rsquo;s people landed in the decade after the journey home.</p>

										<content:encoded><![CDATA[<p class="article-byline">Research compiled for the Lewis and Clark Research Database</p>
<h2>Lewis the Governor and Clark the Brigadier General</h2>
<p>Planning, exploration and most of the reporting phase of the Lewis and Clark expedition was over. The realities of governing the complex Upper Louisiana Territory settled in on the newly appointed Governor Lewis and Brigadier General Clark. Editing and printing of the Lewis and Clark Journals by Lewis, and returning Sheheke and his family to their home at the Mandan Villages by Clark, were the primary responsibilities outlined by President Jefferson and Secretary of War Dearborn.</p>
<p>The time between March 1807 and October 1809 has been examined by noted Lewis and Clark writers and scholars. In August 1807, Lewis returned to his mother&#8217;s home in Virginia, following his report to Jefferson and the initial work in Philadelphia to publish the Journals. Lewis then traveled to Richmond in September to observe the Burr Treason Trial.</p>
<p>A document of more than 10,500 words describing Lewis&#8217; Observations and Reflections relating to the American Indian People and the fur trade in the Upper Louisiana Territory is attributed in part to this period. This document shows that Lewis was developing a framework for governing the territory and establishing a solid economic foundation.</p>
<h2>The Journey to St. Louis</h2>
<p>Late 1807 or early 1808, Lewis departed Ivy, Virginia for St. Louis via the Great Valley Road, the Boone Trace and Wilderness Road. His traveling companions were John Pernier, his free mulatto servant, and Reuben Lewis, his younger brother. Lewis was honored at a public dinner in Lexington, Kentucky. Lewis arrived in St. Louis on 8 March 1808.</p>
<h2>Governing in a Multi-Faceted Culture</h2>
<p>In 1808, cultural changes were sweeping the country. The Spanish style of governing was still strong in the minds of the former French and Spanish citizens. General Wilkinson&#8217;s self-serving influence and Aaron Burr&#8217;s seditious followers had their own agenda. United States policy and the cultural differences with the American Indian Nations added a destabilizing factor, made even more difficult by the British efforts to influence the Tribal People.</p>
<p>During the expedition Lewis and Clark were truly military commanders without bureaucrats second-guessing every decision. Now people 1,000 miles to the East required written communications which slowed territorial governance. At the very best, it required a month of travel time to send documents or letters to Washington.</p>
<h2>Accomplishments 1807-1809</h2>
<p>Even with the challenges, a great deal was accomplished:</p>
<ul>
<li>Improved strength of Fort Bellevue (later Fort Madison) near the Iowa-Missouri border</li>
<li>Packaged and shipped the 1807 Big Bone Lick bones to Thomas Jefferson</li>
<li>Assisted in establishing the <em>Missouri Gazette</em> by editor Joseph Charless</li>
<li>Clark crossed Missouri, guided by Nathan Boone, to build Fort Osage east of present-day Kansas City</li>
<li>Negotiated a Treaty with the Osage Indians</li>
<li>Lewis wrote and published the Territorial Laws</li>
<li>Completed work on the Observations and Reflections for Secretary Dearborn</li>
<li>Organized the St. Louis Missouri Fur Company</li>
<li>Successfully returned Sheheke and his family to their home on the upper Missouri River</li>
<li>Appointed Daniel Boone to serve as Justice of the Peace</li>
</ul>
<h2>Lewis&#8217;s Death, 1809</h2>
<p>Governor Lewis&#8217;s tragic death on October 11, 1809, along the Natchez Trace near present-day Hohenwald, Tennessee, remains one of the enduring mysteries of American history. Clark would go on to ensure that the expedition journals were eventually published and continued his distinguished career as Superintendent of Indian Affairs in St. Louis until his death in 1838.</p>
