"When Thomas Jefferson sent a team of explorers to discover a way to the Pacific Ocean two hundred years ago, the western border of the United States was the Mississippi River. It was Jefferson's dream to uncover the mysteries of the distant lands beyond. In 1803, the president sent a team of thirty men, lead by Meriwether Lewis and William Clark, up the Missouri River, across the Rocky Mountains, down the Columbia River to the Pacific, and back home again. During this monumental, two-and-a-half-year expedition, Lewis and Clark gathered samples of plants, animals, and Indian crafts. Into the Wilderness describes the difficult yet successful journey that made these men the celebrated heroes they are today. James J. Holmberg, curator of special collections at the Filson Historical Society, is the author of Dear Brother: Letters of William Clark to Jonathan Clark.

For two centuries the question has persisted: Was Meriwether Lewis's death a suicide, an accident, or a homicide? By His Own Hand? is the first book to carefully analyze the evidence and consider the murder-versus-suicide debate within its full historical context. The historian contributors to this volume follow the format of a postmortem court trial, dissecting the case from different perspectives. A documents section permits readers to examine the key written evidence for themselves and reach their own conclusions.

Over the course of his career, American explorer William Clark (1770-1838) wrote at least forty-five letters to his older brother Jonathan, including six that were written during the epic Lewis and Clark Expedition. This book publishes many of these letters for the first time, revealing important details about the expedition, the mysterious death of Meriwether Lewis, the status of Clark's slave York (the first African American known to have crossed the continent from coast to coast), and other matters of historical significance. There are letters concerning the establishment of the Corps of Discovery's first winter camp in December 1803, preparations for setting out into the country west of Fort Mandan in 1805, and Clark's 1807 fossil dig at Big Bone Lick, Kentucky. There are also letters about Lewis's disturbed final days that shed light on whether he committed suicide or was murdered. Still other letters chronicle the fate of York after the expedition; we learn the details of Clark and York's falling out and subsequent alienation. Together the letters and the richly informative introductions and annotations by James J. Holmberg provide valuable insights into the lives of Lewis and Clark and the world of Jeffersonian America.
